How to hire independent contractors, from scope to closeout

Key takeaways

Hiring an independent contractor starts with the work, the working relationship and the places connected to it. The decisions continue through candidate selection, agreement, acceptance and access removal. A contractor title alone does not settle status.

• Check the planned working relationship and the relevant jurisdiction before you source. US federal tax, UK employment-status and off-payroll questions, and EU national routes use different frameworks. Get local advice when the arrangement is unclear or crosses borders.
• Define the result you need, how you will accept it, who owns the internal decision and what changes require a new agreement. Build in time and budget for review, rework and administration alongside the contractor’s rate.
• Assess candidates through work that matches the assignment: relevant samples, references, a focused conversation and, where appropriate, a paid first milestone. Give clear feedback and do not treat a recommendation or trial as a guarantee of project quality.
• Put the working terms in writing before work begins. Cover scope, deadlines, changes, confidentiality, data roles, payment terms and the intended rights in the finished work. Keep the signed rights record with the accepted deliverable.
• Collect the documents that fit the person and payment, give only the access required for the work, and keep a usable record of decisions, agreements, invoices, acceptance and changes. A platform can organise parts of this work, but the business still needs to understand its own responsibilities.
• Revisit the arrangement when the work, contract or day-to-day practice changes. At closeout, confirm acceptance and rights, settle open obligations, retain the necessary record and remove access that the contractor no longer needs.

Is an independent contractor right for this work?

An independent engagement starts with the work you need done, not with the title you plan to use. A defined result, room for the contractor to organise their own work and a clear end point often make the arrangement practical. If the role will instead become part of your day-to-day organisation, pause before you source and assess the working relationship under the rules that apply to it.

When a defined project suits an independent engagement

Start with an outcome you can describe and assess: a design system, a security review, a set of translated materials or a migration completed to an agreed standard. Write down the deliverables, acceptance criteria, budget, deadline and the person on your side who can make decisions. That gives both sides a working basis before messages, revisions and invoices start to scatter across tools.

The arrangement is easier to manage when the contractor can propose how to reach the agreed result and when you can review work against the outcome rather than supervise every hour. A short, bounded assignment may be a useful first engagement. A longer project can still have phases, each with its own result, review point and record of acceptance.

When an employee or another route may fit better

Reconsider the arrangement when the work looks like an ongoing role inside your business: you expect the person to follow your daily direction, fit a fixed internal schedule, use your processes as a standing team member or take on work with no defined endpoint. Those facts do not produce one answer everywhere, but they are a reason to assess the actual relationship before describing it as independent work.

Location matters as much as the job design. US, UK and EU status frameworks differ, and a cross-border engagement can involve more than one relevant regime. Ask where the work is performed, which parties are contracting and how the work will operate in practice. Seek local review when those answers are uncertain or the engagement changes shape.

What the contractor needs from the arrangement

The contractor needs enough information to decide whether the work fits and to deliver it without guessing. Share the required result, the agreed rate or milestone terms, the review process, who can approve decisions, the access needed and the handling of confidential information or personal data. Put the agreed terms and the intended rights in the finished work in writing before work starts.

Do not presume that every candidate wants the same arrangement. In the US Bureau of Labor Statistics’ July 2023 survey of employed independent contractors aged 16 and over whose sole or main job was independent contracting, 80.3% preferred that arrangement. The remaining responses included 8.3% who preferred a different arrangement, 8.9% who said it depended and 2.5% whose preference was unavailable. Those figures describe incumbent US workers, not applicants, other countries or legal classification.

Use that range as a prompt for a direct conversation, not as a prediction about any individual. Confirm the practical terms before either side commits: what success looks like, how changes are handled, when payment is due, where records will live and what happens when the assignment closes.

Check status and location before you source

Check the actual engagement before you begin a candidate search. The name “independent contractor” does not determine status on its own, and there is no single global test. Map the work, the parties and where they connect, then use the route that applies to that engagement.

What the working relationship actually looks like

Write down how the work will happen before you describe the role externally. Identify who decides the result and the method, who sets the working pattern and which entity signs the agreement and pays for the work. Record whether the person runs a distinct project or takes continuing direction inside your organisation. These details make the status inquiry more useful than a job title or a standard template.

Keep the record of that inquiry with the agreement. If the project grows, the reporting line changes or a new contract replaces the old one, revisit the facts. A classification decision that matched a short assignment may need a fresh look when the work changes in practice.

Which location and legal tests apply

Start with the places that have a real connection to the work: where the contractor performs it, where the client is established and which entity contracts with them. Then identify the specific tax, employment-rights, social-security or off-payroll question you need to answer. Use the applicable test for each question.

Place and question	What to establish	Limit of the answer
United States: federal employment tax	Gather evidence of behavioural control, financial control and the parties’ relationship under the IRS common-law inquiry.	This inquiry does not settle separate state or local questions.
United Kingdom: status and off-payroll working	Assess rights and tax status separately; check whether services are supplied through an intermediary and whether the client rules apply.	The off-payroll rules are conditional, not a step for every UK contractor.
European Union: national status	Identify the relevant Member State’s route for the status question. Germany offers a status-determination procedure for its national context.	EU social-security coordination does not supply one EU-wide labour-status test.

Whatever you do, do not use your US form independent contractor agreement without adjustments.

— Yana Zubareva

The agreement should follow the engagement and the applicable law. That may mean local review before signature. A familiar form is not automatically portable across countries.

United States: federal tax status and other tests

For US federal employment-tax common-law classification, the IRS says the substance of the relationship governs rather than its label. Its guidance groups relevant evidence into behavioural control, financial control and the type of relationship between the parties. Use those categories to collect facts about the planned work; they do not turn a job title into an answer.

Other US rules can use their own tests. Keep the federal tax inquiry in its proper scope and obtain advice on any separate state or local question that applies to your engagement.

United Kingdom: rights status and conditional off-payroll rules

UK guidance recognises that a contractor can be self-employed, a worker or an employee in the circumstances it describes. Tax status and employment-law status may also differ for the same person, so one label does not resolve every rights or tax question.

The off-payroll working rules concern services supplied through a worker’s intermediary under the conditions in the UK guidance. They are not a universal step for every contractor engagement. For covered public-sector clients and medium or large private or voluntary-sector clients, the client has specified responsibilities; small private clients are treated differently. A wholly overseas organisation without a UK connection is outside the client rules described by HMRC, with the intermediary responsible for determining whether the rules apply.

European Union: national status rules

The European Commission’s social-security coordination guidance does not create an EU-wide contractor labour-status test. Member States determine who is treated as pursuing an employed activity for national social-security purposes, and that category need not match the national labour-law definition of an employee.

Use the relevant national route instead of treating “EU contractor” as a legal category. In Germany, the pension insurance authority’s status-determination procedure can clarify whether a contract relationship involves self-employed activity or dependent employment. Its Clearingstelle assesses each case from the documents and facts provided.

When to seek local review

Seek local review when the facts point in more than one direction, the contractor will work across borders, the client and contracting entity are in different places, or the role changes after you have started. It is also sensible to ask for advice before relying on a status determination to make tax, rights, social-security or off-payroll decisions outside the framework that produced it.

Bring the practical record with you: the proposed scope, reporting arrangements, control over the work, locations, parties, payment structure and any intermediary. That gives the reviewer something concrete to assess and gives your team a record to revisit if the engagement changes.

Define the project and its full cost

Define the work before you compare rates. A low quoted rate does not make an engagement predictable if nobody has agreed what the contractor will deliver, who accepts it or how changes will be priced. Your project brief should turn the business need into a result, a review path and a record your finance and delivery teams can use.

Deliverables, acceptance and an internal owner

Describe the required result and the standard you will use to assess it. US federal performance-based procurement guidance offers a useful private-project model: specify the result and measurable performance standards rather than prescribing every step of the method. It is a drafting approach, not a rule that governs a private contractor agreement.

For each phase, name the deliverable, the evidence that shows it is complete, the date for review and the person authorised to accept it. A software migration might require a tested release and handover notes; a design assignment might require agreed files, formats and approval against the brief. Record acceptance when it happens, because an accepted output is easier to connect to an invoice, a rights record and a later closeout check.

Give the contractor one internal owner who can answer questions and make timely decisions. If a steering group needs to approve major choices, say who collects that decision and how long it normally takes. Otherwise, a contractor can be waiting for input while the deadline and budget continue to move.

Rates, milestones and payment terms

Choose a payment structure that matches the work you can inspect. A short, defined outcome may suit a fixed milestone; open-ended specialist support may need a time-based arrangement with an agreed review rhythm. In either case, write down what triggers an invoice, who approves it, when payment is due and how a disputed item is handled.

Break longer work into milestones when that gives you and the contractor a real decision point. Each milestone should identify the work covered, its amount or rate basis, the expected evidence of completion and the next action after review. Do not leave a change request to a chat thread: document its effect on scope, timing and price before it becomes a source of disagreement.

Budget for review, rework and administration

Plan for the work around the deliverable as well as the work that creates it. Your internal owner needs time to prepare the brief, answer questions, review outputs and approve invoices. Legal or local advisers may need to review the proposed arrangement; finance may need the correct documents; security or IT may need to provision and later remove access.

Set aside a decision path for rework and new requests. Ask at the start whether a correction falls within the agreed acceptance standard or creates a change to the assignment. That distinction keeps the cost discussion tied to the work you asked for and gives both sides a record when the scope grows.

Keep an engagement record that connects the scope, approved changes, acceptance, invoice and payment. It gives your team a practical basis for the next milestone, a renewal decision or a clean closeout without reconstructing the project from scattered messages.

Find and assess candidates

Choose candidates against the work you have defined, then give each person a fair way to show relevant capability. A referral, marketplace profile or polished portfolio can create a useful shortlist, but none replaces a conversation about the actual deliverable, working terms and evidence of comparable work.

Referrals, specialist communities and talent marketplaces

Use more than one sourcing route when the role is specialised or time-sensitive. Referrals can surface people who have worked in a similar setting; specialist communities can reach a narrower discipline; talent marketplaces can give you a structured place to receive proposals. Decide in advance what information every candidate must provide, so the first source does not set a lower standard than the next.

Recommendations deserve the same scrutiny as any other lead. In John Joseph Horton’s historical randomised oDesk experiment, recommendations increased the rate at which technical vacancies were filled, but the study found no detectable hiring effect for nontechnical vacancies and could not determine whether recommended matches had better project quality. Treat a recommendation as a reason to look closely, not proof that the person fits your assignment.

Relevant work samples, references and interviews

Ask for evidence that resembles the work you need completed. A portfolio is more useful when you can identify the contractor’s contribution, the constraints of the project and the result they delivered. For a technical assignment, discuss a comparable implementation or review a focused example. For a creative or research assignment, ask how the person developed, revised and handed over similar work.

References can clarify how the contractor communicates, handles changes and meets agreed deadlines. Ask questions tied to the assignment and the reference’s direct experience. In the interview, explain the scope, decision-maker, review rhythm and access constraints, then make space for the candidate to identify assumptions or dependencies you have missed.

Compare candidates against the same written criteria. That makes the decision easier to explain internally and gives you a sound basis for choosing a first milestone.

A paid first milestone and fair feedback

A short paid milestone can test a bounded part of the work when a sample alone cannot answer the practical question. Agree the result, time frame, fee, review standard and ownership terms first. The work should be proportionate to the decision you need to make; it should not become unpaid production work disguised as an assessment.

A paid trial is fine, but don’t ask anyone to do work for free.

— Katherine Plumhoff

Amanda Pallais’s 2014 randomised oDesk experiment gave 952 hired workers short paid data-entry jobs and public evaluations, then measured their later platform employment and earnings. It did not measure whether hiring clients made better selections. Use a paid first milestone because it gives both sides a clear, fair way to inspect a defined piece of work, not because it guarantees a better project outcome.

Give timely, specific feedback after the milestone, whether you continue or not. Record the acceptance decision and any agreed next scope so the following engagement starts from the same understanding.

Put the agreement and rights in order

Put the core operating decisions into the agreement before work begins: the result, how changes are approved, who handles confidential information and data, and what rights you intend to receive in the finished work. Keep the subsequent decisions with the agreement so the record matches the work.

Scope, changes, deadlines and termination

Begin with the required result and a practical acceptance standard. Add the timeline, milestones, dependencies, the decision-maker and the point at which either side can end the work.

State how a change becomes part of the assignment. A new feature, different format, delayed input or extra review cycle can affect the date, price and acceptance standard. Ask for the change in writing, identify its effect and have the authorised people agree it before the contractor begins the added work.

It can't hurt to say in the contract that if the scope of work changes, your deadline is also subject to change, and vice versa.

— Vinay Jain

Keep the change record alongside the original scope. It gives both sides a reference when a milestone is reviewed and prevents the final invoice from carrying work that was never clearly agreed.

Confidentiality, data roles and access terms

Describe the information the contractor may receive, the purpose for using it, the people who may access it and how access ends. Use the actual data flow to determine whether the contractor processes personal data for your organisation or acts in another role. Do not rely on a generic confidentiality clause to answer a data-protection question it does not address.

Under UK GDPR guidance, a controller that uses a processor to process personal data needs a binding written contract or qualifying legal arrangement for that processing. EU GDPR Article 28 likewise requires a binding contract or legal act when a processor acts on a controller’s behalf, with specified details about the processing; the agreement can be electronic. Those requirements apply when the relevant roles and law apply, so confirm them against the real engagement.

Set the access terms in the same record: which systems or materials the contractor needs, who approves access, what may be copied or retained and what happens when the assignment ends. Your security process can then remove or change access without guessing what the contractor was authorised to use.

Intellectual property and the signed rights chain

Delivery of a file and ownership of the rights in that work are separate questions. Under US copyright law, owning a physical or digital copy does not itself transfer copyright in the work embodied in it. If you need a US copyright ownership transfer, the law generally requires a writing signed by the rights owner or an authorised agent.

Use a record chain that connects the requested result, the acceptance evidence and the intended rights instrument.

For a specially commissioned work made for hire under US law, the Copyright Office identifies specific eligible-work categories and signed written-agreement conditions. Do not assume that commissioning a work, paying an invoice or receiving the files establishes the rights you intended to receive. Other jurisdictions have their own rules, so obtain local advice where the work, parties or rights are connected outside the US.

Retain the signed rights document with the final accepted deliverable and any applicable change records. That makes the rights position easier to check when you reuse the work, renew the engagement or close it.

Prepare the contractor to start

Prepare the record and access path before the first day of work. The goal is not to collect every possible document. It is to identify the contracting party, obtain the documents that fit the person and payment, give the contractor the access needed for the assignment and preserve a record that your team can use later.

Identity, eligibility and tax documents

Confirm who will sign the agreement and receive payment, then match your document request to that person and the applicable rules. For US tax documentation, the IRS requester instructions use Form W-9 to request a US person’s taxpayer identification number and certifications. They direct foreign persons to the appropriate Form W-8 or Form 8233 where applicable. A W-9 is not a universal form for every international contractor.

Treat work eligibility and local tax questions as jurisdiction-specific. Where the location, nationality, entity structure or nature of the assignment creates a question, identify the relevant local route before work begins. Keep only the information your process and applicable obligations require, and make clear who can access it.

Tools, access and a clear point of contact

Give the contractor access that matches the agreed scope: the systems, files, workspace or accounts needed to complete the defined work. Name one point of contact for practical questions and a decision-maker for approval. The contractor should know how to request missing access, report a problem and submit work for review.

Record who approved each access grant and when it should end. NIST’s access-control catalog describes disabling accounts when they are no longer associated with a user; outside its federal context, that is a useful operational model for your exit process. Set the owner and removal path when you grant access. At closeout, the team can use that record to confirm what to remove.

Avoid giving a contractor broad credentials because they may prove useful later. Start with what the assignment requires, change access through a recorded request and review it when the scope changes.

What to record before work begins

Create one engagement record that your delivery, finance and security teams can find. It should connect the signed agreement, scope and acceptance criteria, approved rate or milestone terms, tax or payment documents that apply, access approvals, the internal owner and the communication route for changes.

Add the date work may begin and the first review point. If a contractor will process personal data, record the role assessment and the contract terms that apply to it. That gives you a clear starting position for the first invoice, a change request, a status review or the final removal of access.

Keep the record current as facts change. A new scope, intermediary, contracting entity or access need should update the same file set, so the next person who reviews the engagement sees the current arrangement and its approval history.

Manage the work without losing the record

Manage the engagement against the agreed result, and keep the decisions close to the documents they affect. A clear record makes routine delivery easier to review and gives you a reliable history when the scope, status or relationship changes.

Deliverable reviews and changes in practice

Review each deliverable against the acceptance standard in the agreement. Record whether you accepted it, requested a correction or agreed a change in scope. Put the decision, date and responsible approver where finance and the project owner can find them; a chat message alone is easy to lose when a later invoice or rights question arises.

When working practice changes, revisit the engagement as well as the schedule. A new reporting pattern, different control over the work, continuing responsibilities or a replacement contract can alter the facts you considered at the start. For covered UK off-payroll cases, HMRC says a change in working practices or a new contract requires the rules to be rechecked. Keep that obligation within its UK scope, but use the same habit of reassessment whenever a material change alters your arrangement.

Acceptance, invoices and payment records

Connect an invoice to the milestone or time period it covers, the approved rate or price basis and the acceptance or review record. If part of the work is disputed, record what was accepted, what needs correction and what both sides agreed about the next action. That prevents a payment discussion from becoming a reconstruction of the project.

Give your finance team the agreed payment terms, the relevant contracting party and the supporting documents before payment is due. Keep the invoice and payment record with the agreement, scope and change history. The complete set is more useful than a single “paid” status when you need to explain what the business received.

Records to retain for renewal or a dispute

Retain a record that follows the engagement from decision to closeout: status inquiry where applicable, signed agreement, scope, approved changes, access approvals, deliverables, acceptance evidence, invoices, payments and the rights documents that apply to the work. Maintain a version that reflects the current arrangement when the practical work changes.

Covered UK off-payroll clients have specific recordkeeping duties. HMRC requires detailed records of status determinations and their reasons, fees paid, and the contractors and intermediaries engaged. Those are UK requirements for the covered cases, not a universal list, but they show why a reasoned decision and its supporting facts should remain available.

Set a review point before renewal and before a dispute forces the issue. The person who approved the original engagement should be able to see what changed, what was accepted and which obligations are still open without searching across individual inboxes.

Decide whether an administrative platform helps

Choose the operating model that matches the part of the engagement you need to manage. Finding talent, signing and administering an engagement, and retaining its records are related jobs, but they do not always come from the same service. Start by identifying where your team is losing time or control: candidate discovery, agreement administration, invoice handling, document history or closeout.

Direct contracts, talent marketplaces and administration

A direct contract gives your business a close working relationship with the contractor and leaves your team to run the records and process. A talent marketplace can structure proposals, project communication and marketplace payment for work arranged through that marketplace. These are useful options when the immediate decision is how to discover and assess candidates.

Administrative support becomes relevant after you have chosen the contractor and need a repeatable way to handle the engagement. 4dev.com’s Contractor Platform covers post-selection contractor administration, including document and status checks, an agreement, invoices, tasks, closing documents and engagement history. That scope answers a different question from where you find the person to hire.

Map your own process before choosing a provider. If candidate sourcing works well but agreements, approval records and closeout documents are scattered, administration may be the gap. If you have no suitable candidate, solve the sourcing question first instead of expecting an administrative workflow to supply one.

Which responsibilities remain with the business

Keep ownership of the decisions that only your business can make about the work: who to engage, what result is required, who accepts it and when the practical arrangement has changed. Document the handoff between your team and any provider so an invoice, status question or closeout task has a named owner.

For covered UK off-payroll cases, outsourcing responsibilities does not remove the organisation’s accountability for operating the rules effectively. That is a specific UK example, but it is a useful prompt for every operating model: understand what the provider performs, what evidence it keeps and what decision your business still needs to make.

Do not assume a provider takes on classification risk, local legal review, tax filing, immigration verification or a particular data-protection role unless its actual service terms state that scope. The agreement with the provider should make the division of work clear before you rely on it.

What to verify in a provider's service terms

Read the service terms with the same attention you give the contractor agreement. Ask who signs which agreement, who collects and retains documents, how invoicing and payment records work, what you can export, and how the record is handed back at closeout. If the provider handles personal data, identify the controller and processor roles and the contract terms that apply to that processing.

Also ask what happens when the engagement changes: a new scope, different contracting entity, extension, dispute or exit. Confirm who updates the record, who removes access and who provides the documents your finance, legal or security teams may need. A clear answer at the start is more useful than trying to assign responsibility after a record is missing.

Compare terms against your own operating gaps and the provider’s stated responsibilities. The right model is the one that gives your team a usable agreement, decision trail and closeout record for the contractors you have already chosen.

Renew, convert or close the engagement

Treat renewal, conversion and closeout as new operating decisions, not as automatic extensions of the first agreement. Review what the contractor actually did, what remains open and whether the next phase still matches the arrangement you assessed at the start.

Recheck status when work changes

Recheck the practical relationship when the work becomes ongoing, the contractor takes on a different role, a new intermediary or entity is introduced, or the way you direct and review the work changes. Bring forward the original status record, compare it with the current facts and seek local review where the change raises a new question.

For covered UK off-payroll cases, HMRC requires a recheck when working practices change or a new contract is negotiated. That is a UK-specific obligation, but it captures a useful general discipline: a renewal should test the present arrangement on its current facts.

If an ongoing role points to a different engagement route, pause before extending the contractor agreement. The appropriate conversion process depends on the relevant jurisdiction, parties and facts, so obtain the local advice needed for that decision.

Confirm final acceptance and rights

Before the final payment or renewal decision, confirm which deliverables were accepted, what correction or handover remains and which records support the decision. Tie each accepted output to the scope, any approved changes and the invoice or payment record. This gives you and the contractor a clear account of what the engagement produced.

Check the rights record separately from delivery. Under US copyright law, receiving a physical or digital copy does not by itself transfer copyright in the work. A US copyright ownership transfer generally requires a written instrument signed by the rights owner or an authorised agent. Where US law applies, retain that signed instrument with the accepted work; other jurisdictions require their own rights review.

If you renew, make the next scope and rights position explicit for the new deliverables. If you close, identify who holds the final files, acceptance evidence and signed documents so your business can retrieve them later.

Remove access and settle open obligations

Close access in a deliberate sequence. List the accounts, repositories, shared folders, devices or other resources associated with the assignment, identify their owners and confirm removal or adjustment after the contractor no longer needs them. NIST’s access-control catalog describes disabling accounts when they are no longer associated with a user; outside its federal context, it provides a useful model for an access-exit check.

Settle outstanding obligations alongside the access review: unaccepted work, agreed corrections, invoices, reimbursement or expense questions where applicable, return or deletion of information under the agreement, and any final documents. Record the closeout date and the person who confirmed each item.

Keep the closeout record with the agreement and engagement history. The team can then see what ended, what was accepted and what access was removed if a later audit or dispute arises.

Frequently asked questions

Can a small business hire an independent contractor?

Yes, provided the actual engagement fits the applicable rules and your business can run the agreement and recordkeeping process. Start with the work, the working relationship, the parties and the location before you source. A small team can keep the process proportionate by defining the result, naming an internal owner and retaining the agreement, acceptance and payment record in one place.

How long can a contractor work for one client?

Treat duration as one fact to assess alongside the actual working relationship, location and applicable regime. Recheck the arrangement when it continues, changes in practice or moves to a new contract. The original status inquiry may no longer describe the work.

Does every contractor need a W-9 or a 1099-NEC?

No. The IRS requester instructions use Form W-9 to request a US person’s taxpayer identification number and certifications; they direct foreign persons to the appropriate Form W-8 or Form 8233 where applicable. Whether a 1099-NEC is required depends on the relevant US reporting rules and the facts of the payment. Confirm the applicable requirement instead of treating either form as a universal contractor document.

Does IR35 apply to every UK contractor?

No. The UK off-payroll working rules concern services supplied through a worker’s intermediary under the conditions in the guidance. Covered public-sector clients and medium or large private or voluntary-sector clients have specified responsibilities, while small private clients are treated differently. A wholly overseas organisation without a UK connection is outside the client rules described by HMRC. Check the intermediary, client and connection facts before deciding whether the rules are in scope.

Do contractors need benefits or fixed hours?

Do not use a label alone to answer the question. Assess the actual work, the degree of control, the jurisdiction and the status framework that applies to the engagement. In the UK, for example, tax and employment-law status can differ for the same person.

Can a hiring platform make a contractor compliant?

A platform can organise parts of the engagement, such as documents, agreements, invoices and records, but its actual service terms determine the work it performs. Your business still needs to understand the working relationship and the responsibilities it retains. For covered UK off-payroll cases, HMRC says outsourcing responsibilities does not remove the organisation’s accountability for operating the rules effectively.

Before relying on any provider, confirm who determines status, who signs and retains records, how personal-data roles are addressed, and whether the contract states any assumed responsibility for local review, tax, classification or other obligations.
