How IR35 off-payroll rules affect UK copywriting contracts and pricing

What to take away

What IR35 off-payroll rules mean for copywriting contracts

IR35 is the set of tax rules that apply when a worker provides services through an intermediary, usually a limited company, but would have been an employee of the client if engaged directly. The off-payroll working rules extend that logic to the client's payroll for medium and large organisations.

HMRC calls the test one of employment status, and it looks at the reality of the working relationship rather than the label on the contract.

For a copywriter, the practical question is simple. Do you work like a business, with your own equipment, your own risk and control over how the work is done? Or do you work like an employee, taking instructions, working set hours and being treated as part of the client's team?

If the second description fits, the engagement is inside IR35.

The rules apply to copywriting contracts when the writer operates through a personal service company, a partnership or another intermediary. Sole traders are outside the off-payroll rules because they are already taxed as self-employed, but they still face the same employment status questions if HMRC challenges their self-employment.

Copywriting is a mixed occupation. A retained writer who attends daily editorial meetings, uses the client's laptop and writes only for that client looks like an employee. A project writer who prices by the job, uses their own software and can send a substitute looks like a business.

Most real contracts sit between those two, which is why the paperwork matters.

A contract that says 'outside IR35' proves nothing on its own. HMRC and tribunals look at what happens in practice. If the contract says the writer controls the work but the client's marketing director sets every deadline and reviews every sentence, the contract is weak evidence. The working relationship usually decides the case.

Who decides employment status and when

Since April 2021, the end client decides employment status for contracts with public sector bodies and medium or large private sector clients. The client must take reasonable care and issue a Status Determination Statement to the worker and any agency in the chain. The reasons behind the decision have to be set out in the statement.

A client counts as small if it meets two or more of these tests: annual turnover of no more than £10.2 million, a balance sheet total of no more than £5.1 million, or no more than 50 employees. Small clients are exempt from the off-payroll rules.

For those engagements, the contractor's own company decides status and accounts for tax through the deemed payment rules.

When a client is exempt, the risk sits with the contractor. A copywriter working for a small agency or a start-up should not assume the client has checked anything. The writer may need to run their own status test and keep the evidence.

Agencies in the chain have duties too. If an agency supplies the copywriter, the agency must pass on the Status Determination Statement and may become responsible for deducting tax if the client fails to provide one. Agencies that ignore this can end up liable for the tax that should have been withheld.

Disagreement is possible. A worker who disagrees with a determination can ask the client for the reasons and use the client's disagreement process. If that fails, the worker can ask HMRC to review the decision. The process is slow, so most disputes are settled by changing the working arrangements rather than by formal challenge.

Public sector clients, including government departments, councils and the NHS, have applied the off-payroll rules since 2017. A copywriter with a public sector contract should expect a determination and a payroll route from the start.

Documentation for copywriting freelancers and agencies

The strongest IR35 documentation shows that the client buys a service, not a person. The contract should describe the deliverable, the fee and the writer's control over how the work is done. It should allow substitution, avoid exclusivity and avoid notice periods that look like employment.

A well-drafted contract is not a guarantee, but it is the first thing an HMRC officer reads.

Acas publishes useful guidance on employment contracts and the difference between employees and other workers. The same principles help when writing a copywriting contract: state the services, the payment terms and who controls the work. Employment contracts | Acas is a sensible reference for clients who are unsure where the line sits.

A statement of work is often more useful than a long overarching agreement. It should list each project, the fee, the deadline and the acceptance criteria. If the writer can choose when and where to work, say so. If the client provides equipment or software, explain why and whether the writer could use their own.

Working practice evidence matters as much as the contract. Keep emails that show you declined work, set your own hours or sent a substitute. Keep invoices that show project fees rather than monthly salary-like payments. Keep a record of other clients and your own marketing activity. These details support the business-like picture.

Agencies should keep a determination file for each contractor. It should include the Status Determination Statement, the reasons for it, the contract and any changes to working practice. If HMRC enquires, the agency can show it took reasonable care. Without that file, the agency may be treated as the fee-payer and face the tax bill.

Before you sign copywriting services commercial contracts, check who owns the words and who carries the risk if the status decision changes. Ownership clauses and indemnities interact with IR35 because they show who controls the output and the commercial risk. commercial contracts should be reviewed together with the status position, not separately.

Pricing implications of inside and outside IR35

Inside IR35, the client or agency deducts income tax and National Insurance from the fee before paying the contractor's company. The contractor then takes the net amount as salary or dividends, but the tax has already been paid at employee-like rates. The take-home pay is lower than the same gross fee outside IR35.

Most inside IR35 contractors use an umbrella company or the client's payroll. Umbrella companies charge a margin, often a weekly or monthly fee, and they process the deductions. The contractor should compare the net pay, not the headline rate, before accepting an inside IR35 contract.

Outside IR35, the contractor's company invoices the full fee and pays corporation tax on its profits. The contractor can choose a salary and dividends, and can claim legitimate business expenses. The difference in net income between inside and outside can be substantial, which is why day rates for inside IR35 work are often higher.

The client's budget also changes. An inside IR35 engagement costs the client more in employer National Insurance and apprenticeship levy if the client payrolls the worker. Some clients pass that cost on by reducing the day rate. Others absorb it. The negotiation should start from the net pay the contractor needs.

Corporation tax rates affect the outside IR35 calculation. A copywriter's company pays corporation tax on profits, so the rate matters when comparing routes. The published rates are on Rates and allowances for Corporation Tax - GOV.UK. Accountants use those rates to model the net pay from a given day rate.

Business costs also feed into pricing. Software, insurance, accountancy fees and marketing are deductible for an outside IR35 company. Inside IR35, many of those costs are no longer tax-deductible in the same way. The GOV.UK money and tax section covers the wider tax picture for business costs and pricing at Money and tax - GOV.UK.

When you compare copywriting services pricing models, model the net pay under both routes. A higher inside IR35 day rate can still leave less money than a lower outside IR35 rate. pricing models should include the tax treatment, not just the headline fee.

Checklist for contract reviews and status tests

Use this checklist before signing a copywriting contract or renewing a retainer. It is not legal advice, but it covers the points HMRC and clients usually examine.

Run the status test as a set of steps.

A worked example helps. A copywriter charges £500 a day outside IR35 for a six-month project. The client is a large retailer, so the off-payroll rules apply.

The client determines the role inside IR35 because the writer attends daily stand-ups and uses the client's laptop. The agency deducts tax and National Insurance, and the umbrella fee is £25 a week.

The writer's net pay falls by roughly a third. The writer then renegotiates the day rate to £650 to reach the same net figure. The contract is redrafted to remove the daily stand-up and the client laptop, but the client still determines inside IR35 because the role is part of the team.

The writer accepts the inside rate for the project and reviews the arrangement at renewal.

Common IR35 mistakes in copywriting engagements

One common mistake is assuming a limited company automatically means outside IR35. The company structure is the reason the rules apply, not a defence against them. HMRC looks at the working relationship, not the incorporation certificate.

Another mistake is relying on a contract clause that says 'outside IR35' while the working practice says otherwise. Tribunals give more weight to what actually happens. If the client controls the work, the clause will not save the engagement.

A third mistake is ignoring the client's size. A copywriter working for a small client may be responsible for the status decision and the tax. Many freelancers do not check whether the client is exempt, and they assume the client has handled it.

A fourth mistake is pricing inside IR35 work at the same rate as outside IR35 work. The net pay is lower, so the day rate should reflect the deductions and the umbrella fee. Writers who skip this step can lose a large part of their income.

A fifth mistake is poor record keeping. Without contracts, statements of work and working practice evidence, a writer cannot show that the engagement was outside IR35. HMRC can then treat the income as inside IR35 and issue a tax bill.

A sixth mistake is ignoring the agency chain. Agencies that fail to pass on a Status Determination Statement can become liable for the tax. Clients and agencies should keep the determination file and review it when the contract changes.

Different copywriting services business models differ on risk, headcount and cash flow, and IR35 interacts with each of them. business models differ explains how a solo writer, a studio and an agency carry different status risks.
