Hiring contractors in Spain

A foreign business can engage a Spain-based contractor for genuinely autonomous services, but employee status depends on who organises and directs the work, whatever the agreement or autónomo registration says. 4dev.com is a global contractor platform working with contractors in Spain; its Contractor Platform handles contracts and documents, with any IP assignment depending on the agreement. Once the working arrangement is clear, check whether TRADE status and the invoice rules apply.

Where the line runs between employment and autónomo work

Start with who directs the work. Paid services performed within the client’s organisation and direction fall on the employment side; autónomo services are carried out on the provider’s own account, outside that direction. The Workers’ Statute also presumes an employment contract where a person provides paid services under another party’s organisation and direction. The service agreement should therefore reflect the real arrangement, rather than try to rename it.

Feature	Employee pattern	Autonomous service pattern
Direction of the work	The client directs the work within its organisation.	The provider carries out an economic or professional activity outside the client’s direction and organisation.
Hours and methods	The client determines how the individual performs the role as part of its working structure.	The client agrees the service output; the provider retains control over how to perform it.
Place in the organisation	The individual supplies work within the client’s business structure.	The provider delivers a service on their own account, separate from that structure.

Read these patterns together; they are not a points test. A client may specify the result, quality standard and delivery date, but daily supervision, prescribed methods or a place within the client’s team point toward employment. Scope the service and record the deliverables and acceptance standard at the outset. Revisit the arrangement if the client starts directing hours or methods; only a genuinely autonomous service calls for the separate TRADE analysis.

Where contractor status breaks: TRADE and false autónomo

TRADE is a further test for a genuinely self-employed provider. At least 75% of relevant income must come from one client, and all other statutory conditions must hold; that income share cannot turn client-directed work into autonomous work. The Self-Employed Workers Statute sets the status; it does not create a percentage-only safe harbour.

The 75% calculation is a second test

The denominator includes income from work and economic or professional activities, including employee wages; it excludes capital returns, gains from personal assets and proceeds from transferring business assets. In a hypothetical example, €60,000 from Client A, €15,000 from other clients and €5,000 of employee wages produce €60,000 ÷ (€60,000 + €15,000 + €5,000) = 75%; the calculation illustrates the denominator only and does not establish TRADE status.

Income test	At least 75% of work, economic and professional income must come from one client. Employee wages enter the denominator; the specified capital and asset proceeds do not.	BOE Self-Employed Statute; BOE TRADE regulation
Independence	The provider must independently organise the activity, use their own economically relevant infrastructure, perform work differentiated from the client’s employees, and be paid for the result while bearing commercial risk. All conditions apply together.	BOE Self-Employed Statute
Staff and subcontracting	A TRADE provider generally may not employ staff or subcontract the activity. Narrow exceptions allow one employee for specified pregnancy, birth/adoption or family-care circumstances.	BOE Self-Employed Statute
Exclusions	Holders of commercial or industrial premises or public-facing offices, and professionals practising jointly in a corporate or other legal form, cannot be TRADE. This is separate from the income test.	BOE Self-Employed Statute
Annual interruption	18 working days, which the contract or a professional-interest agreement may improve.	BOE Self-Employed Statute

The route below starts with the working relationship, then moves through income share, the remaining conditions and formalities.

All TRADE conditions and the client notice

The provider must tell the client that they consider themselves economically dependent; without that communication, they cannot use the TRADE legal regime. The contract must be in writing, expressly record the dependent status and be registered, and the status can attach to only one client. The client may ask for evidence of the conditions when the agreement is made and later, normally no more often than every six months.

The TRADE implementing regulation sets the filing handoff. The provider has 10 working days after signing to register the agreement and five more working days to notify the client; if the client has received no registration notice within 15 working days of signature, the client must register it in the following 10 working days. Keep the written notice, registration confirmation and agreed evidence with the agreement, then reassess the arrangement when the client’s direction or the provider’s income mix changes.

How a Spanish contractor registers before work

An autonomous provider registers with the tax authority and Social Security before starting activity. The buyer can request evidence of those registrations, while the provider remains responsible for the filings.

Tax census and Social Security

An autónomo files Modelo 036 before starting business or professional activity, carrying out the relevant transactions, or incurring a withholding obligation. Modelo 037 was abolished on 3 February 2025; its simplified census route now sits within Modelo 036. Registration in the Special Regime for Self-Employed Workers (RETA) must be communicated before activity starts and may be filed up to 60 calendar days beforehand through Seguridad Social.

Incorporation does not by itself settle RETA coverage for an owner who works in the company. Effective control includes holding at least half of the capital; the statute also has rebuttable presumptions at one third, or one quarter together with management functions, and for specified family holdings. Ask the supplier for the registration evidence that matches its form, rather than treating a company certificate as a universal answer.

Can a non-EU resident work as an autónomo in Spain?

Permission depends on the person’s current residence and work rights and the proposed own-account activity; Modelo 036 or RETA registration is not itself immigration authorisation. For an initial own-account route, authorisation becomes effective only after the required visa and timely Social Security alta, and its initial scope is limited to one year, one autonomous community and one activity sector. A long-term resident may have work rights on the same conditions as Spaniards, while a non-lucrative residence authorisation does not permit professional activity, so verify the individual status rather than infer permission from residence alone.

What RETA bands actually mean

For 2026, the provider chooses a contribution base within the minimum and maximum attached to their forecast net-earnings band. These figures are base choices for Social Security contributions, not a fixed contribution amount, a tax rate, an exemption threshold or a test of whether the activity is independent.

Forecast net earnings up to €670 / month	Available contribution base: €653.59–€718.94 / month, the first reduced-table band. The provider chooses within the range.	Seguridad Social 2026 RETA table
Forecast net earnings above €6,000 / month	Available contribution base: €1,928.10–€5,101.20 / month, the highest published general-table band. The provider chooses within the range.	Seguridad Social 2026 RETA table

The forecast is provisional. Seguridad Social’s 2026 base table is later regularised against annual earnings data: a shortfall is due by the end of the month after notification without late interest or surcharge when paid in that period, while an overpayment above the final band maximum is refunded on the statutory timetable. This later reconciliation is the provider’s duty; the buyer needs evidence of registration.

What the Spanish services contract needs

The services agreement should define the result, the provider’s discretion in delivering it and any rights the client needs in the work. Actual conduct still determines whether the arrangement is autonomous.

Scope, autonomy, data and intellectual property

Specify deliverables, acceptance criteria and the provider’s control over methods. If the work involves confidential information or personal data, set out the handling obligations in the agreement. The client can set the required output and quality standard while leaving day-to-day methods to the provider.

For copyright created through the service, a written exploitation-rights assignment should name the rights, modes of exploitation, time and territory being assigned. If the agreement omits the time, the assignment is limited to five years; if it omits territory, it is limited to the country in which the assignment is made. If it does not specifically identify the modes of exploitation, it extends only as far as is necessary to fulfil the contract’s purpose.

The statutory presumption that an employer owns exploitation rights in software created by an employee within assigned duties applies to employees. It does not settle rights in contractor-created software, so those rights need their own analysis and, where intended, a written assignment.

Ending the contract

An ordinary autonomous commercial agreement ends under the terms the parties have agreed. A TRADE agreement has a more specific written framework: it identifies the parties and economic dependence, describes the work and result-linked consideration, and addresses interruption and activity time. The statutory 18-working-day annual interruption remains part of that framework, subject to improvements in the agreement or a professional-interest agreement.

There is no universal contractor notice period. A TRADE contract may set notice and termination compensation, while the statutory rule otherwise looks to the agreed notice or relevant trade custom. If the client ends a TRADE contract without justified cause, damages may be due; where the amount is not set, the assessment considers the remaining term, seriousness of the breach, the provider’s advance investments and expenses, and the notice given. A TRADE agreement that specifies neither a term nor a particular service is presumed indefinite unless rebutted.

What should appear on the first invoice

A full invoice identifies the parties and service, but its tax treatment also depends on the business customer’s status and the establishment that receives the service. For ordinary B2B services, settle those customer facts before deciding the Spanish VAT and withholding treatment.

Invoice identity and fields

A business or professional service generally requires an invoice, and a full invoice needs a sequential number and, where used, series; the issue date and transaction date when different; the supplier’s and customer’s names and tax identifiers where required; and a description sufficient to determine the taxable amount. It also states the tax rate and tax amount, or the relevant exemption or reverse-charge wording. Use the AEAT invoice-content guidance to check the fields before issue, rather than building the document around a generic cross-border template.

Spain, another EU country or outside the EU

For ordinary B2B services, the customer’s seat or the establishment receiving the service determines the place-of-supply analysis. The matrix below is a starting point for those ordinary services; specific territorial rules and service exceptions can change the answer.

Business customer	Spanish VAT treatment for ordinary B2B services	ROI/Modelo 349	Spanish IRPF withholding check
Spanish business or receiving establishment in Spain	Assess Spanish VAT. The standard rate is 21% where Spanish VAT applies, subject to reduced rates, exemptions and territorial rules.	Not an intra-EU service report.	Check whether this payer is among the parties obliged to withhold.
Qualifying EU business customer	The customer is normally the VAT taxable person under the ordinary B2B rule.	The Spain-based provider may need ROI/NIF-IVA registration and must report qualifying services on Modelo 349.	Check the payer’s Spanish withholding status; do not infer it from EU location alone.
Business customer outside the EU	The ordinary B2B rule generally places the service outside Spanish VAT when the customer is abroad.	No intra-EU ROI/Modelo 349 route for that customer.	Check the payer’s Spanish withholding status rather than assuming a foreign client withholds.

The AEAT guidance on international services sets the ordinary customer-location rule. Spanish professional income is generally subject to 15% withholding when the payer is obliged to withhold; a qualifying new professional activity can use 7% in its start year and the following two years. That rate does not answer whether a particular overseas client is a Spanish withholding payer.

Two different electronic-invoicing clocks

Spain’s B2B electronic-exchange rule and the SIF/VERI*FACTU invoicing-software rules have different gates and dates. The B2B rule applies where the business customer has a Spanish seat, a Spanish establishment receiving the service, or, failing that, qualifying Spanish residence; a Spain-based supplier does not put every foreign-client invoice inside that scope. Ordinary simplified invoices are excluded unless they are qualified simplified invoices under the regulation.

The B2B clock began with the implementing order effective on 6 October 2026. Subject to later amendment, businesses with prior-year turnover above €8 million reach the practical obligation on 6 October 2027, while the rest reach it on 6 October 2028. This turnover-based timetable does not decide the separate SIF software requirement.

SIF/VERI*FACTU concerns the records generated by covered invoicing software: compliant systems keep those records or transmit them to AEAT in VERI*FACTU mode. Corporate income taxpayers covered by the rule need adapted systems before 1 January 2027; other covered taxpayers, including IRPF economic-activity taxpayers, need them before 1 July 2027. Check both tracks independently before changing an invoice process.

How the money reaches a Spanish contractor

Settlement normally follows the agreed bank-transfer route, currency and account details in the contract and invoice. Spain uses the euro, and a Spanish IBAN has 24 characters; confirm the account identifier and beneficiary details before initiating the transfer.

Set out four matters in the agreement and invoice instructions:

• Set the invoice currency in the agreement and show it consistently on the invoice and bank instructions.
• Use the supplier’s confirmed IBAN and the agreed bank-transfer route; a Spanish account uses the 24-character IBAN format described by the Banco de España.
• State how the parties will deal with bank charges. Transfer and conversion charges depend on the relevant bank or service terms, so there is no universal Spanish amount to add to an invoice.
• Treat any currency-conversion choice as a commercial and banking decision. A multi-currency account can hold foreign currency without automatic euro conversion, but it remains subject to the provider’s terms and exchange-rate risk.

Invoice currency does not decide VAT or the due date. The recipient analysis determines VAT; the agreement and applicable commercial-payment rules determine the deadline.

Payment terms and late payment in Spain

Spain’s commercial late-payment rules apply to covered business-to-business and business-to-administration transactions for goods or services, not every unpaid invoice. They exclude consumer transactions, insolvency debts, certain cheque, promissory-note and bill-of-exchange interest, and insurance-damage payments. Check that the service falls within Ley 3/2004 before relying on its deadlines or remedies.

No agreed date or period	Payment is due 30 calendar days after the service.	BOE commercial-payment rules
Contractual extension	The parties may agree a longer period, but not more than 60 calendar days.	BOE commercial-payment rules
Acceptance or verification	A contractual or legal check of the service may last up to 30 calendar days; the statutory payment period is then 30 calendar days after acceptance or verification.	BOE commercial-payment rules
Late interest	It accrues automatically without a demand where the creditor has performed and the debtor is responsible for the delay. The contractual rate applies first; otherwise the statutory rate applies.	BOE commercial-payment rules
Statutory rate	The rate is the ECB main refinancing rate plus eight percentage points, set for each half year. The published rate was 10.15% for the first half of 2026 and 10.40% for the second half of 2026.	BOE first-half 2026 interest notice; BOE second-half 2026 interest notice
Recovery compensation	The creditor may add €40 and documented additional collection costs above that amount. No compensation is due where the debtor is not responsible for the delay.	BOE commercial-payment rules

Put the due date, any acceptance process and the commercial contact for invoice queries in the agreement and on the invoice record. The 30-day default does not allow an acceptance process to run indefinitely, and the 60-day ceiling does not convert an out-of-scope invoice into a covered commercial debt.

What breaks between the contract and invoice

Each step needs an owner: the client knows how the work is directed and where it receives the service; the provider controls its registration, rights grant and invoice. The documents should describe the same arrangement.

Step	Failure	Who fixes it
Role and autonomy	The client directs hours, methods or the person’s place in its organisation while the agreement calls the service independent.	The engagement owner must reassess the route; a label cannot resolve client direction.
Modelo 036 and RETA	The provider starts activity without the required census or self-employed registration.	The provider files the required registrations. The buyer may request evidence but does not file for the provider.
TRADE notice and registration	An economically dependent provider does not notify the client, sign a written TRADE agreement or complete the filing sequence.	The provider communicates the status and registers the agreement; if no registration notice arrives within the statutory window, the client has the follow-on registration duty.
Rights to work output	The contract names a service but leaves exploitation rights, modes, time or territory unspecified.	The parties document the intended written rights assignment; the provider can assign only the rights covered by that agreement.
First invoice	The invoice lacks the required identity, date, service or tax treatment information.	The provider issues the invoice; the customer supplies the recipient details needed for the treatment.
Receiving establishment	The parties use the supplier’s location instead of identifying the customer seat or establishment that receives the service.	The customer confirms the receiving establishment; the provider applies the ordinary B2B analysis to the documented facts.
Electronic-invoicing and software rules	A team treats the B2B exchange timetable as the same rule as SIF/VERI*FACTU software records.	The provider checks both recipient scope and its own taxpayer/software status; the customer provides the location facts relevant to the B2B route.
Acceptance and due date	The contract has no usable acceptance point or payment date, or an acceptance process is used to postpone the statutory timetable.	The parties set the process in the agreement and apply the commercial-payment rules where the transaction is covered.
Ongoing records	The arrangement changes from an independently delivered service into client-directed work, or the provider’s income mix changes.	The engagement owner and provider reassess classification and, where relevant, the TRADE position before relying on earlier documentation.

Keep the agreement, registration evidence, any TRADE notice and confirmation, written rights grant, invoice and receiving-establishment information together. Recheck the file if a new manager directs the work, methods become fixed, the receiving establishment changes or the provider’s income sources shift materially.

What a classification or filing error costs, and who pays

First identify the breached duty. A missed employee registration, a provider’s own RETA omission and prohibited worker supply arise on different facts and carry different consequences.

Party	Risk	Amount
Client or employer	A person is in substance an employee but was not enrolled in Social Security. Failure to register is a serious Social Security infringement for each affected worker.	€3,750–€12,000 per infringement across the statutory severity grades.
Self-employed provider	The provider fails a required RETA enrolment or permitted number of altas under the self-employed filing rule. This is a different Article 22.7(a) ground, attaching to the self-employed worker.	The serious-infringement scale is €3,750–€12,000 where that provision applies.
Supplying and receiving employers	The facts establish prohibited worker supply under Article 43: the arrangement is more than a contractor-status error and meets the statutory supply conditions.	Joint and several employment and Social Security obligations; the worker may choose permanent employment with either employer. The separate very-serious infringement range is €7,501–€225,018.

The Workers’ Statute permits temporary worker supply only through an authorised ETT and identifies the factual routes to prohibited supply. That route does not arise automatically whenever an autónomo is wrongly classified. Where it does apply, the supplying and receiving employers face joint obligations and the worker has the statutory choice of permanent status; the €7,501–€225,018 range is tied to the distinct very-serious infringement.

Past periods need their own calculation. Social Security’s power to determine and collect unpaid contributions generally prescribes after four years, while the tax administration’s assessment and collection rights also generally prescribe after four years. Both periods are subject to statutory interruptions and exceptions, so neither is a universal lookback figure for a particular engagement.

Models and when each fits in Spain

Use a services route for work the provider performs autonomously. If the business needs to direct and integrate the person, assess employment under the actual arrangement.

Model	Documents and workflow	Classification responsibility and boundary
Direct independent contract	The client and provider agree the service scope, acceptance, rights and invoice record directly. The provider keeps its own registration and tax obligations.	Fits a genuinely autonomous service. The client must not turn the relationship into directed work through its day-to-day operating model.
Contractor platform	The parties can administer the services agreement and documents through a platform. Any IP grant depends on the contract.	It supports the contractor workflow, but the real organisation and direction of the service still determine the appropriate route.
Direct employment through the foreign employer or a Spanish entity	The employer holds the employment documentation and registration workflow. A foreign employer without a Spanish work centre can register directly, subject to the applicable corporate documents and a Spain-domiciled legal representative.	Use this route when the business will organise and direct the work as employment. See Hiring in Spain for the employer-registration and cost detail.
Employment through a lawful EOR or ETT arrangement	The employment provider and client need documents that reflect the actual employment and, where relevant, temporary-supply arrangement.	The employer of record label alone is not decisive. Temporary worker supply is restricted to authorised ETTs and the statutory grounds; see Employer of Record in Spain for that model.

For a direct foreign-employer route, Social Security registration uses the employer’s corporate documents, a Spain-domiciled legal representative where there is no Spanish work centre, and the relevant tax and Social Security registrations. An ETT route has a different legal basis: it needs prior administrative authorisation, and temporary supply follows the circumstances in which the user company could lawfully use the matching temporary or training employment route. The Ministry’s public ETT search can be used to check an authorisation number, NIF or legal name.

The permanent-establishment question has its own test. Under domestic Spanish law, a continuous or habitual place of business, or an agent habitually authorised to contract for the nonresident, can create a permanent establishment; an applicable treaty can change the analysis. Assess those facts for the foreign company before relying on a contracting model.

One Spanish contractor versus ten

More contractors mean more individual files, while the autonomy test stays the same. Reuse a sound company template and workflow, then check each role, provider and invoice on its own facts.

Check	One contractor	Ten contractors
Service scope and autonomy	Test who directs the work and record the deliverable, acceptance point and provider discretion for that role.	Apply the same test to every role; a common template does not make differently managed services autonomous.
Provider registration	Obtain the relevant Modelo 036 and RETA evidence from the individual provider where applicable.	Keep the evidence with each provider record; the buyer does not take over the provider’s filing duty.
TRADE	Check the provider’s own income position, notice and written-registration steps if economic dependence is relevant.	Review each provider separately because their income mix, client notice and one-client position can differ.
Contract and IP	Record the scope, ending terms and any written rights assignment for that service.	Use a controlled template, then make each rights grant match the work, rights, modes, time and territory actually intended.
First invoice	Identify the business customer and receiving establishment before applying invoice treatment.	Keep that receiving-establishment check with each invoice stream; different customers or establishments can produce different VAT and e-invoice questions.
Software and payment terms	Check the provider’s covered software status and the agreement’s acceptance and due-date terms.	Keep the same workflow fields across the portfolio, while applying the applicable SIF and B2B exchange gates to each supplier and customer fact pattern.

Reopen an individual file when supervision, the provider’s income mix, the work output or the receiving establishment changes. Those facts can alter classification, TRADE status, rights or invoice treatment even when the contractor count stays the same.

4dev.com

4dev.com’s Contractor Platform covers Spain with standardized agreements, closing documents and IP documentation for distributed teams. Its public materials do not specify a Spanish entity, local documents or Spain-specific IP terms. The Spanish service still needs an independent scope; 4dev.com is not an Employer of Record.

Deel

Deel has a dedicated Spain contractor route and says local legal specialists approve its contracts. Its country material centres classification on autonomy. For a team seeking a localized agreement within a wider platform, the proposed supervision still needs to leave the Spanish provider in control of the work.

G-P

G-P discusses Spanish autónomos, TRADE, direction and integration alongside a services agreement and local invoicing. For an ongoing engagement, its Spain-focused guidance is useful when the buyer needs to establish how independence will work in practice.

WorkMotion

WorkMotion lists contractors on a Spain country page centred largely on employment. Teams weighing both routes need the Spanish contractor agreement and document workflow to assess its contractor option.

Rippling

Rippling’s Spain guide covers contractor onboarding and distinguishes contractors from employees. Existing Rippling users can bring that process to a Spanish engagement, then review the local contract, documents and actual direction of the role.

Boundless

Boundless describes a Spain Agent of Record route with contractor agreements and a classification component. Its discussion of autónomo and outcome-based work makes the proposed project scope central to evaluating that route.

Skuad

Skuad offers an Agent of Record route for Spanish contractors. Its Spain page calls for an agreement under Spanish contract law addressing IP and classification, which makes the exact agreement terms material when comparing it with direct engagement.

Remote

Remote lists contractor management in Spain alongside employment and discusses misclassification in its country guidance. A team considering a later move to employment can compare both routes, starting with the agreement and assessment process for the present contractor role.

Jackson & Frank

Jackson & Frank names Spain among its Contractor of Record markets and describes engagement through local entities. Before choosing it for a Spanish assignment, a Europe-focused buyer needs the entity, governing law and local review details, plus the agreement’s indemnification clause to see how responsibility is allocated.

Rise

Rise’s Spain checklist asks for independently delivered services, a false-self-employment review, a services agreement and registration evidence. Confirm that its coverage reaches the planned assignment and that the deliverables can be performed independently.

Remote People

Remote People discusses Spanish autónomos, written services agreements and false-self-employment review, including when an engagement may need conversion to employment. Its route suits a buyer considering contractor and recruitment support together; the review should respond to the actual degree of direction and integration.

Contra

Contra provides a discovery route for freelancers located in Spain and available for work. For a creative or digital project sourced there, the business and chosen freelancer still need to settle the Spanish service scope, documents and contract terms directly.

PeoplePerHour

PeoplePerHour lists professionals in Spain and lets buyers request proposals, including for language and creative work. The buyer and selected specialist must establish the independent project terms; a Spanish contracting-party role for the marketplace is not published.

FreelanceConnect

FreelanceConnect has company accounts and active projects connecting companies with senior technology freelancers in Spain; it says their conversations and contracts remain direct. It is a sourcing option for a Spanish technology project whose client is prepared to document the operating facts in its own agreement.

RemoFirst

RemoFirst offers a Spain contractor route with locally compliant agreements and treats classification as a route-selection question. For a consulting or project role, ask how its review handles the supervision and integration the client plans.

Playroll

Playroll describes contractor management for independent professionals living in Spain, including local agreement drafting and classification-risk review. Its agreement for a consultant or project specialist needs to reflect the planned deliverables and supervision.

Malt

Malt’s Spanish company marketplace creates contracts from project conditions and stores confidentiality, IP and other legal documents; it also publishes a Madrid address. For digital, technical or creative sourcing, review whether the generated terms contain the rights and autonomy provisions the particular Spanish project needs.

Arc

Arc’s Spain marketplace lists vetted remote developers available for freelance or contractor work. Engineering teams can use it to source technical talent, then document a distinct project scope and independent working method after selection.

Freelancer

Freelancer’s Spain-filtered marketplace lists data analysts with profiles available for hire. It can source data or AI work; the buyer and selected professional still set the Spanish agreement and operating model.

freelancermap

freelancermap lists Spain-based IT, SAP and technology specialists with skills and availability filters. A company needing that expertise can search the directory, then request the candidate’s business documentation and proposed independent-services terms.

Workana

Workana’s Spain route lets a company post a project and choose among freelancer proposals. For digital, design, marketing or technology work, the selected professional and client need project terms that describe the independent service they will actually perform.

Contractor questions about Spain

Can a US company hire an independent contractor in Spain?

Yes, a US company may engage genuinely autonomous services from a Spain-based contractor, but the working arrangement decides the classification. If the company organises and directs paid work as an employer would, the employment test can apply despite the contract title or the company’s location. The customer’s receiving establishment and status must also be identified before applying the invoice rules.

Does autónomo registration prove someone is independent?

No. An autónomo registration does not replace the test of whether the person works outside the client’s organisation and direction. The contract, registration and daily operating facts should point in the same direction; where they do not, the factual relationship governs the analysis.

Does 75% from one client automatically make a freelancer TRADE?

No. The 75% test is only one requirement for economically dependent self-employed worker (TRADE) status, and it applies after genuine autonomy has been established. The worker must also meet the statutory conditions, communicate the status, and use a written, registered agreement; the relationship may concern only one dependent client.

Does a Spanish contractor charge VAT to a foreign business?

For ordinary B2B services, the starting point is the establishment of the business customer that receives the service, rather than the contractor’s address alone. A Spain-based provider’s service to a business customer abroad will generally not carry Spanish VAT, but special territorial rules can apply. For a qualifying customer in another EU Member State, the provider should also check ROI and Modelo 349 requirements.

Does an overseas client withhold Spanish IRPF?

Spanish IRPF withholding depends on the payer’s status. Specified payers include Spanish businesses and certain non-residents with a Spanish permanent establishment, so an overseas client must check its position. Where withholding applies to professional income, the general rate is 15%, with a qualifying 7% rate for the start year and the next two years.

When do the B2B e-invoice and SIF rules apply?

The B2B electronic-invoice rule is recipient-location based: it covers qualifying business customers whose Spanish seat, receiving establishment, or qualifying residence receives the service, with an exception for ordinary simplified invoices. Its rollout is 6 October 2027 for businesses above €8 million prior-year turnover and 6 October 2028 for others, provided the timetable is not amended. SIF is a separate software-record rule, with covered corporate taxpayers due before 1 January 2027 and other covered taxpayers before 1 July 2027.

Can I receive monthly invoices from a Spanish contractor?

Monthly invoicing can be a practical commercial arrangement when it accurately documents the services supplied and the agreed billing cycle. Each full invoice still needs its sequential number or series, issue date, service date where different, party details, description and applicable tax information. A monthly billing cycle does not remove those invoice requirements.

When should a contractor become an employee?

Move to employment analysis when the client begins to organise and direct the person’s paid work, such as by controlling how the service is performed or integrating the person into its organisation. A contractor’s registration or a services agreement does not cure those facts. Reassess when the role, supervision or operating model changes instead of waiting for a particular headcount or duration.
