Employer of record vs payroll provider: 8 key differences


Contents
Key takeaways
- Identify the employer first. In an EOR arrangement, the EOR is the legal employer. A payroll provider administers agreed tasks for an employer; under US payroll service provider rules, the buyer remains the employer. That EOR role is described by the UK Office of Tax Simplification.
- Set out who does each payroll task. A US employer using a payroll service provider remains liable for federal employment tax; a UK employer remains responsible for PAYE tasks it outsources. Specify filing roles and the records you can inspect. See IRS Publication 15 and GOV.UK payroll guidance.
- Check registration before assuming you need an EOR. Employer registration and incorporation are separate questions. A foreign employer can obtain a German business number without a German seat or branch when social insurance reporting requires one. EU guidance also requires an employer hiring in another member state to register locally. Check the full rules for your hire.
- Test the actual arrangement. Ask for the employing entity, payroll identifiers, written duty allocation, any required local authority and the transition terms before signing. Compare quotes against the same scope of service.
What each model means
An EOR and a payroll provider can appear in the same hiring plan, but they answer different questions. Begin with the legal person named as employer. Then work through registration, payroll duties and the local rules that apply to the proposed arrangement.
Employer of record
An EOR is the legal employer of the workforce in the model described by the UK Office of Tax Simplification. The practical starting point is therefore simple: identify the exact legal entity that will employ the worker and appear in the employment documentation (The Office of Tax Simplification’s definition of an EOR).
That label does not answer every operating question. Before relying on an EOR arrangement, you still need the proposed contract and local rules to show how employment duties, payroll work, benefits, leave, reporting and any required authority apply to the actual hire.
Payroll provider
A payroll provider performs tasks that the employer delegates. In US guidance, a payroll service provider may prepare paychecks, employment-tax returns and Forms W-2, and make federal tax deposits or other federal payments for the employer. It performs those functions using the employer’s EIN (IRS Publication 15).
The service scope can be broader or narrower than calculations and filings. In the UK, a provider may also keep employee records, issue payslips and make HMRC payments, depending on the service purchased. Read the schedule of duties before treating any of those tasks as included, and ask which employer or payer identifier will be used for each filing or deposit (GOV.UK’s payroll guidance).
Related models that should not be conflated
Third-party payer, co-employer, agency and EOR describe different parts of a workforce arrangement. Identify the specific structure before carrying conclusions about employer status or tax liability from one model into another.
Professional employer organization
In US federal-tax guidance, a professional employer organization (PEO) is a type of third-party payer. A PEO may claim to share control over employees as a co-employer, but the Internal Revenue Code does not define the term “co-employer” or recognize it as a federal tax-law classification. That is why a PEO should not be treated as a simple synonym for either a payroll service provider or an EOR (IRS guidance on PEO arrangements).
Staffing or temporary-work agency
A staffing or temporary-work agency is another structure that requires its own review. EU temporary-agency-work rules apply to contracts or relationships connecting a worker with a temporary agency, and they set a principle of nondiscrimination in essential work and employment conditions compared with workers recruited by the user company. Whether those rules apply to a proposed arrangement depends on its actual contracts and local law (European Commission guidance on temporary agency workers).
Eight differences that change the decision
Compare the proposed arrangements across eight points, starting with the legal employer. The answers to registration, payroll and local-law questions follow from that choice.
1. Who is named as the employer
An EOR is the legal employer in the model described by the UK Office of Tax Simplification. That makes the identity of the employing entity the first item to settle in an EOR proposal. That employer role appears in the Office of Tax Simplification’s EOR definition.
Payroll support does not by itself change that identity. In the US, a payroll service provider performs its functions using the employer’s EIN. Ask the provider to name the legal employer in writing and show which employer or payer identifier applies to the payroll activities in scope. The IRS distinguishes this US arrangement from other third-party payer categories.
2. Whether the buyer needs to be able to register as employer
When your company intends to employ directly, payroll support follows your ability to meet the employer requirements for that hire. Employer registration and incorporation are separate questions, and the answer depends on the country and facts.
For example, an employer based abroad can obtain a German business number when it must report German-employed workers to social insurance, even without a German seat or branch. In the EU cross-border context, an employer hiring in another member state must register with local authorities to meet local labour, social-security and tax rules (German Federal Employment Agency guidance and Your Europe guidance).
The UK illustrates the same need to separate the questions: an overseas company with no UK base does not need Companies House overseas-company registration solely for that reason, while Corporation Tax registration may still arise. That point does not exempt an employer from PAYE obligations. (GOV.UK overseas-company guidance). Ask local advisers whether direct employer registration is available and appropriate for your actual hire before selecting a model.
3. Employment agreement and day-to-day direction
The employment agreement should identify the employing entity. Day-to-day direction is a separate part of the working relationship, and the proposed division of duties needs to fit the relevant local rules as well as the contract.
US federal tax guidance shows why the practical arrangement matters: a worker is generally an employee when the business has the right to control what work is done and how it is done, even where the worker has freedom of action. That is a US rule, not a universal allocation of responsibility between an EOR and the buyer. Review the actual management relationship and the local classification rules for the hire (IRS Publication 15).
4. Payroll calculation, filings and statutory deposits
Payroll providers can take on substantial administrative work. Under US guidance, a payroll service provider may prepare paychecks, employment-tax returns and Forms W-2, as well as make federal tax deposits and other federal tax payments for the employer. The provider performs those functions under the employer’s EIN (IRS Publication 15).
Delegation does not make the buyer’s responsibility disappear. A US employer using a payroll service provider remains liable for federal employment-tax obligations, and the IRS advises the employer to confirm federal deposits through EFTPS. In the UK, an employer remains legally responsible for PAYE tasks even when it pays another party to perform them (IRS Publication 15 and GOV.UK payroll guidance).
For each country, ask who calculates the payroll, who files, who makes the statutory deposit, which identifier is used and what confirmation you can access after payment. The answer may differ by payer category and contract, so keep the duty schedule with your employment and payroll records.
5. Benefits, leave and HR administration
Benefits, leave and HR administration require a different comparison from payroll calculations. With an EOR, begin with the entity named as legal employer and ask that entity to set out its duties. With direct employment and payroll support, begin with your company’s employer duties and identify the limited tasks you are delegating. The provider label does not establish a universal allocation in either arrangement.
Put these questions into the contract review:
- For an EOR arrangement, which legal entity administers each benefit and leave process, which records does it maintain, and what information or approvals stay with your company?
- For direct employment with payroll support, which records, payslips and payments will the provider administer, and which benefit and leave duties will your company retain?
- If the arrangement falls under EU temporary-agency-work rules, how will the proposed terms meet the requirement for nondiscrimination in essential work and employment conditions compared with workers recruited by the user company?
The UK illustrates the second comparison: a payroll provider may keep employee records, issue payslips and make HMRC payments, depending on the service purchased (GOV.UK payroll guidance). Where the EU temporary-agency-work framework applies, the nondiscrimination check in the final question is required (European Commission guidance on temporary agency workers).
6. Employment-law and worker-classification responsibilities
Employment-law and classification duties depend on the actual relationship, local law and the parties’ agreement. A service label cannot settle the allocation.
The US payroll rules illustrate why the payer category matters. An employer using a payroll service provider remains liable for its federal employment-tax obligations. An authorized Form 2678 agent and the employer are jointly liable for the duties the agent is authorized to perform; a section 3504 designated payer uses its own EIN and also shares liability for its designated tax duties. IRS Publication 15 distinguishes those arrangements.
Worker classification needs the same fact-specific review. For US federal tax purposes, employee status generally follows the right to control what work is done and how it is done. In the UK, an employer remains legally responsible for PAYE tasks even when another party performs them (IRS Publication 15 and GOV.UK payroll guidance). Ask for a written allocation of duties, but do not treat it as a substitute for the local rule that governs the relationship.
7. Local labour-supply rules and provider authority
The proposed country may regulate the arrangement through which a third party employs a worker who performs work for your company. An EOR label alone does not establish whether a particular labour-supply rule applies.
Germany provides a clear example. A business that lends employees to another business generally needs a permit under the German Employee Leasing Act (AÜG). Request the provider’s relevant permit or a written, country-specific explanation of why the proposed structure does not require one (German Federal Employment Agency guidance on employee leasing).
EU temporary-agency-work rules apply to contracts or relationships connecting a worker with a temporary agency and include protections for the worker. That framework reinforces the need to review the actual contracts and local authority for the proposed hire, rather than relying on a country-wide permission for EOR services (European Commission guidance on temporary agency workers).
8. Transition, scale and exit planning
Plan a change of employer before you sign the first arrangement. A move from an EOR to direct employment, or a switch between employer arrangements, may require contract, payroll and local-law work. Do not assume it automatically transfers employment terms, continuity or leave.
In the UK, TUPE can transfer employment contracts, including terms, holiday entitlement and continuity of employment, where that regime applies. The rule does not apply automatically to every EOR conversion. That limitation is explicit in GOV.UK guidance on transfers and takeovers.
As the arrangement expands, check whether the provider can repeat the handoff for every affected worker without losing records or filings. Request a worker-level transition schedule. For a UK move under a different employer reference, it should name the old and new references, the record handoff and the submissions required at each payroll cutoff.
The UK provides a concrete test. In the circumstances covered by HMRC guidance, moving employees to a payroll under a different employer reference requires payroll-record transfer and separate old- and new-employer submissions. Where EU temporary-agency-work rules apply, member states must void or allow voiding clauses that prevent the user undertaking from employing the agency worker. (GOV.UK guidance on payroll changes and European Commission guidance on temporary agency workers). Request the exit terms and country-specific transition steps before committing to either model.
Use a two-gate decision process
Choose the employer model in order. First decide whether your company can and should employ the worker directly. Then, if another party will employ the worker, test the proposed arrangement under the rules of that country.
Gate one: can and should your company be the employer?
Start with the direct-employment route for the actual country and hire. A local entity is not the whole answer: employer registration, incorporation and tax presence are separate questions. In Germany, an overseas employer can obtain a business number when it must report German-employed workers to social insurance, even without a German seat or branch. Across the EU, an employer hiring in another member state must register with local authorities (German Federal Employment Agency guidance and Your Europe guidance).

Use this gate to map the registrations and employer duties that apply before comparing payroll support. It does not answer whether your company may employ directly in every case. The UK example is similarly narrow: an overseas company with no UK base does not need Companies House registration solely for that reason, though other registration obligations may still arise (GOV.UK’s overseas-company guidance).
Start by deciding whether your company is prepared to be the employer for this hire, then assess the payroll support or third-party employment structure that follows. That order keeps a service label from standing in for the country-specific registration, contract and labour-supply questions that still need answers.
— Mike Smirnov
If your company can and chooses to employ directly, define the registration plan and the payroll tasks you will delegate. If it cannot or should not take that role for this hire, move to the second gate and examine the third-party arrangement itself.
Gate two: if a third party employs the worker, is the arrangement documented and permitted?
If a third party will employ the worker, identify that legal entity and obtain the employment documentation that names it. An EOR is the legal employer in the model described by the UK Office of Tax Simplification, but the label does not establish the labour-supply rules that apply in a specific country. The Office of Tax Simplification’s EOR definition answers the employer-identity part of the question.
Next, check the actual arrangement against local rules. In Germany, a business that lends employees to another business generally needs an AÜG permit. EU temporary-agency-work rules apply to contracts or relationships connecting a worker with a temporary agency and include a principle of nondiscrimination in essential work and employment conditions (German Federal Employment Agency guidance on employee leasing and European Commission guidance on temporary agency workers).
Ask the provider for the proposed employer entity, the relevant contract, any required permit or a written explanation of why none is required, and the transition terms. Resolve any gap in those documents before relying on the arrangement.
Questions to put to a provider before signing
Request documents you can inspect: the employing entity and contract, the payroll duty schedule, local authority and exit plan. Keep the answers together for the hire.
Employer and contract proof
Request the full legal name of the entity that will employ the worker and the employment documentation that names it. An EOR is the legal employer in the model described by the UK Office of Tax Simplification, so the proposed employing entity must be clear before you approve the arrangement (The Office of Tax Simplification’s EOR definition).

Ask the provider to explain the working relationship as well as the contract party. In US federal-tax guidance, employee status generally follows the right to control what work is done and how it is done. Review the actual management arrangement with the relevant local rules in mind (IRS Publication 15).
Ask the provider to document one pay cycle from employment agreement to statutory payment: name the employing entity, the filing or payer identifier, the delegated tasks and the records you can inspect. A clear answer gives the buyer a practical way to test the proposed arrangement before relying on a broad promise of payroll or compliance support.
— Mike Smirnov
Keep the entity name, contract and duty allocation together in your approval record. Those documents give finance, HR and counsel a common starting point for the later registration and payroll checks.
Registration, filing and deposit proof
Ask for the employer, agent or payer identifier that applies to each payroll activity. In a US payroll service provider arrangement, the provider performs its functions under the employer’s EIN. The identifier should match the proposed duty schedule and the records you receive (IRS Publication 15).
Request written answers to these questions:
- Which party prepares and files each return?
- Which party makes each statutory deposit, and under whose identifier?
- What access or confirmation will you receive after a payment or filing?
For US federal deposits, the IRS advises an employer using a payroll service provider to confirm payments through EFTPS. In the UK, an employer remains legally responsible for PAYE tasks even when another party performs them (IRS Publication 15 and GOV.UK payroll guidance). Save the replies with the agreement so finance can reconcile the work that was promised with the work that occurred.
Local arrangement and transition proof
Ask the provider to explain in writing how the proposed arrangement is authorized in the worker’s country. Where the structure requires a permit, request it; where it does not, request the country-specific reasoning. In Germany, a business that lends employees to another business generally needs an AÜG permit, but an EOR label alone does not establish that the rule applies to every arrangement (German Federal Employment Agency guidance on employee leasing).
Request the exit terms before the first worker starts. Where EU temporary-agency-work rules apply, member states must void or allow voiding clauses that prevent the user undertaking from employing the agency worker. For a UK move to a new employer reference in the circumstances covered by HMRC guidance, payroll records must transfer and the old and new employers make separate submissions (European Commission guidance on temporary agency workers and GOV.UK guidance on payroll changes).
The file for each country should contain the local-authority basis, the employment and payroll handoff steps, and the party responsible for each action. That record gives you a starting point if the arrangement changes later.
When an EOR is usually the stronger fit
An EOR is usually the stronger fit when your company decides it cannot or should not be the direct employer for a particular hire, and the provider can document a lawful, workable third-party employment arrangement in that country. In this model, the EOR is the legal employer of the workforce (The UK Office of Tax Simplification’s EOR definition).
Use that conclusion only after reviewing the proposed country and structure. The provider should identify the employing entity, supply the relevant contract, explain the allocation of duties and show the required local authority or why it is unnecessary. In Germany, for example, a business that lends employees to another business generally needs an AÜG permit; the EOR label alone does not decide whether that rule applies. That conditional requirement comes from the German Federal Employment Agency.
An EOR proposal is ready for comparison when you can trace one hire from employment agreement through payroll and statutory tasks to an eventual exit. If the provider cannot show those documents and steps for the country concerned, resolve that gap before treating the EOR route as the stronger option.
When direct employment with payroll support is usually the stronger fit
Direct employment with payroll support is usually the stronger fit when your company can and chooses to be the employer for the hire, then delegates defined payroll tasks. The decision turns on the registration, tax, employment and operational requirements for the actual country; it does not follow from a generic entity or headcount rule.
Check the direct-registration route first. An employer based abroad can obtain a German business number when it must report German-employed workers to social insurance, even without a German seat or branch. In the EU cross-border context, an employer hiring in another member state must register with local authorities. Those examples do not establish direct-employer eligibility in every case (German Federal Employment Agency guidance and Your Europe guidance).
Once your company takes the employer role, set out the payroll duties you want the provider to perform and retain the evidence needed to oversee them. In the US, a payroll service provider performs its functions under the employer’s EIN, while the employer remains liable for federal employment-tax obligations. In the UK, an employer remains legally responsible for PAYE tasks even when another party performs them (IRS Publication 15 and GOV.UK payroll guidance).
Country examples that show why labels are not enough
The same provider label can cover different legal and administrative arrangements across countries. These examples show why you need to identify the employer, payer category, registration path and local authority for the actual hire.
United States: payroll service provider duties and EINs
In the US, a payroll service provider may prepare paychecks, employment-tax returns and Forms W-2, and make federal tax deposits or other federal tax payments for the employer. It performs those functions using the employer’s EIN. The employer remains liable for federal employment-tax obligations, so delegated administration does not remove the need for oversight (IRS Publication 15).
The payer category can change the details. A reporting agent is a type of payroll service provider and performs authorized functions using the employer’s EIN. An agent authorized on Form 2678 and the employer are jointly liable for the tax duties the agent performs. A section 3504 designated payer uses its own EIN and shares liability with the employer for the federal tax duties designated under the service agreement.
Ask which category the provider uses, whose EIN appears in the workflow, who files each return, and how you can confirm deposits. The IRS advises employers using a payroll service provider to confirm federal tax deposits through EFTPS. Keep those answers in the approval record with the provider’s duty schedule.
United Kingdom: outsourced PAYE tasks and employer responsibility
In the UK, an employer remains legally responsible for completing PAYE tasks even when it pays someone else to perform them. That rule makes payroll outsourcing a delegation of work, not a complete handoff of the employer’s PAYE responsibility (GOV.UK guidance on running payroll).
The provider’s scope may extend beyond calculations and filings. Depending on the service, a UK payroll provider may keep employee records, provide payslips and make payments to HMRC. Put the included tasks, the responsible party and the records you can inspect into the agreement before you rely on that scope (GOV.UK’s payroll guidance).
Germany and the EU: employer registration and employee-leasing questions
For a German-employed worker, an employer based abroad can obtain a business number when it must report the worker to social insurance, even without a German seat or branch. More broadly, an employer hiring in another EU country must register with local authorities to comply with local labour, social-security and tax rules. Those registration paths do not establish that every overseas employer may directly employ in every fact pattern (German Federal Employment Agency guidance and Your Europe guidance).
Employee leasing is a separate question. In Germany, a business that lends employees to another business generally needs an AÜG permit. The EOR label alone does not determine whether that rule applies, so review the actual contracts and working arrangement (German Federal Employment Agency guidance on employee leasing).
Where EU temporary-agency-work rules cover the relationship, they apply to contracts or relationships connecting a worker with a temporary agency and require nondiscrimination in essential work and employment conditions. Get country-specific advice on the proposed structure; the service label alone cannot determine which rules apply (European Commission guidance on temporary agency workers).
Frequently asked questions
These answers address the employer role, registration and transition questions that usually determine the choice.
Do you need a local entity to use a payroll provider?
Not always, but a payroll provider does not decide the question for you. Whether your company needs a local entity, employer registration or another step depends on the country and the facts of the hire.
For example, an overseas company with no UK base does not need Companies House overseas-company registration solely on that basis, although Corporation Tax registration may still arise; that point is not a PAYE exemption. In Germany, an employer based abroad can obtain a business number when it must report German-employed workers to social insurance, even without a German seat or branch (GOV.UK’s overseas-company guidance and German Federal Employment Agency guidance).
Across the EU, an employer hiring in another member state must register with local authorities to comply with local labour, social-security and tax rules. Ask local advisers about the specific employer, worker and country before choosing direct employment with payroll support or an EOR (Your Europe guidance).
Who is the legal employer with an EOR?
In the EOR model described by the UK Office of Tax Simplification, the EOR is the legal employer of the workforce. Ask the provider for the full legal name of the entity that will employ the worker and ensure that entity appears in the employment documentation (The Office of Tax Simplification’s EOR definition).
The employer name alone does not settle payroll, benefits, management direction or local authority requirements. Review the proposed contract and country-specific rules for the actual arrangement.
Does outsourcing payroll remove employer responsibility?
No, not in the US federal and UK PAYE rules covered here. A US employer using a payroll service provider remains liable for federal employment-tax obligations. In the UK, an employer remains legally responsible for PAYE tasks even when it pays someone else to perform them (IRS Publication 15 and GOV.UK payroll guidance).
Outsourcing can delegate calculations, filings, payments and records within the agreed scope. Ask who performs each task, which identifier is used and how you will confirm the filings and deposits. The applicable country rules and contract determine the responsibility for your arrangement.
Is an EOR permitted in every country?
Do not treat an EOR label as a country-wide permission. Whether a third-party employment arrangement is permitted depends on the actual structure, the worker’s country and the local rules that apply.
Germany shows why the distinction matters. A business that lends employees to another business generally needs a permit under the German Employee Leasing Act (AÜG). The EOR label alone does not establish that employee-leasing rule applies to every EOR arrangement. That conditional requirement comes from the German Federal Employment Agency.
Where EU temporary-agency-work rules apply, they cover contracts or relationships connecting a worker with a temporary agency and include protections for the worker. Ask the provider to document the proposed employer, arrangement and required authority for the actual country before proceeding (European Commission guidance on temporary agency workers).
Can a company move an employee from an EOR to direct employment?
Yes, but the process depends on the country, the contracts and the payroll arrangement. Do not assume the employee’s terms, service continuity, holiday entitlement or benefits will transfer automatically.
In the UK, TUPE can transfer employment contracts, including prior terms, holiday entitlement and continuity of employment, where it applies. It does not automatically apply to every EOR conversion. If employees move to payroll under a different employer reference in the circumstances covered by HMRC guidance, payroll records must transfer and the old and new employers make separate submissions (GOV.UK guidance on transfers and takeovers and GOV.UK guidance on payroll changes).
Plan the move with the named employer, payroll provider and local advisers before setting a payroll cutoff. Confirm the contract steps, consent or transfer requirements, accrued entitlements, registrations and records that apply to the worker’s country.
