Self-Employed Musician Tax: The Complete UK Guide

I put off doing my first tax return for so long that I nearly missed the deadline. Not because I didn't earn enough to file one — I'd been gigging regularly for over a year — but because nobody had sat me down and explained how self-employed musician tax actually works in the UK. Every guide I found was written for consultants or plumbers. None of them mentioned agency commission, cash-on-the-night payments, or what happens when three different agencies are all deducting different amounts from your fee.

This is the guide I wish I'd had.

Do you need to file a tax return as a musician?

If you earn more than £1,000 in a tax year from performing — and that includes everything from pub gigs to weddings to corporate events — you need to register as self-employed with HMRC and file a Self Assessment tax return.

That £1,000 figure is your trading allowance. It's the total amount you can earn from self-employment before you're required to register. If you're earning less than that, you usually don't need to register or file — unless you want to claim expenses against that income or have another reason to be in Self Assessment. But if you're doing more than a handful of gigs a year, you'll almost certainly be over it.

You need to register with HMRC by 5 October following the end of the tax year in which you started. So if you started gigging in September 2025, you'd need to register by 5 October 2026. Don't leave it until the last minute — registering late can mean a penalty, and it takes time to get your Unique Taxpayer Reference (UTR) through the post.

If you're not sure whether you count as self-employed, the short version is: if you're booking your own gigs, choosing when you work, providing your own equipment, and getting paid a fee rather than a salary, you're self-employed. Most gigging musicians are. Even if you also have a day job.

Understanding the UK tax year (6 April – 5 April)

This trips up more musicians than almost anything else. The UK tax year doesn't run January to December — it runs from 6 April to 5 April the following year. So the 2025/26 tax year started on 6 April 2025 and ends on 5 April 2026.

Why does this matter? Because if you're tracking your income and expenses by calendar year, your figures won't match what HMRC expects. That December gig and that January gig might feel like they belong together, but if one falls before 5 April and the other falls after, they're in different tax years.

Get into the habit of thinking in tax years, not calendar years. It makes everything easier when January rolls around and you're staring at the Self Assessment form.

What income to declare

You need to declare all your self-employed income from performing. Everything. This includes:

• Fees from agencies (we'll come back to how commission affects this in a moment)

• Direct bookings where the client pays you

• Cash payments at venues

• Tips, if you receive them

• Any other performing income — session work, recording fees, teaching if it's part of your self-employed activity

The question that catches most singers out is whether to declare the gross fee (before the agency takes their cut) or the net amount (what actually lands in your bank). The answer depends on how your agency works.

If the agency pays you your fee minus their commission — say the gig pays £200 and you receive £170 after their 15% — then you declare £170 as your income. The commission never reached you, so it's not your income to declare.

If, however, the client pays you the full £200 and you then pay the agency their £30 separately, you declare the full £200 as income and claim the £30 commission as a business expense.

The distinction matters because it changes how your income and expenses appear in your records, even though your taxable profit ends up the same either way. Getting it right keeps things clean if HMRC ever reviews your return. If you're working with multiple agencies that handle commission differently, you need to know which model each one uses. It's worth checking your contracts or simply asking — most agencies will tell you straight. And once you know how your agency handles commission, make sure you're invoicing them correctly too.

For cash payments, you're legally required to declare them even though there's no paper trail. Keep a record of every cash gig: the date, the venue, and the amount. It doesn't need to be complicated — a note on your phone works — but it does need to exist.

Allowable expenses for musicians

This is where you start reducing your tax bill. HMRC lets you deduct "allowable expenses" from your income before calculating your tax. The rule is that the expense must be "wholly and exclusively" for your business — but in practice, quite a lot qualifies.

Here's a quick overview of what most performers can claim:

Equipment and instruments — microphones, PA systems, speakers, stands, cables, in-ear monitors. If you buy it to perform, it's an expense.

Music and backing tracks — subscriptions to backing track services, purchasing individual tracks, music licensing fees.

Performance clothing — this is specific to costumes or stage outfits that you wouldn't wear day-to-day. A sequinned gown you only wear on stage? Claimable. A black dress you also wear to dinner? Probably not.

Marketing and promotion — your website, business cards, professional photos, social media advertising, demo recordings.

Insurance — public liability insurance, equipment insurance.

Phone and broadband — the business proportion. If you use your phone 50% for gig-related calls, emails, and admin, you can claim 50% of the bill.

Software and subscriptions — anything you use for your business. Accounting software, gig management tools, cloud storage for setlists and contracts.

Training — vocal coaching, music courses, workshops that maintain or improve your professional skills.

Agent commission — if you pay it separately from your fee (see the income section above). See the complete guide to invoicing as a freelance singer for how this works in practice.

I've written a full breakdown of every expense musicians can claim with specific examples and edge cases. It's worth reading if you're not sure whether something qualifies.

Mileage allowance (simplified expenses)

If you drive to gigs — and most of us do — mileage is one of the biggest deductions you can claim. HMRC's simplified expenses system lets you claim 45p per mile for the first 10,000 business miles, and 25p per mile after that, without needing to keep fuel receipts or work out your actual running costs.

I covered this in detail in my guide to claiming mileage as a musician, including what counts as a business journey, worked examples, and common mistakes. The short version: if you're driving to 50 gigs a year with an average 60-mile round trip, that's £1,350 straight off your taxable profit.

Most performers I know were either guessing their mileage or not claiming it at all. Either way, they were leaving hundreds of pounds on the table.

How much tax will you actually pay?

This is the question everyone wants answered, and the reason most people's eyes glaze over is that tax guides just list the rates without showing what they mean in practice. So let's walk through a real example.

The 2025/26 rates:

Your personal allowance — the amount you can earn before paying any income tax — is £12,570. After that:

• 20% (basic rate) on income between £12,571 and £50,270

• 40% (higher rate) on income between £50,271 and £125,140

• 45% (additional rate) on income above £125,140

These bands apply in England, Wales, and Northern Ireland. If you're based in Scotland, different rates and bands apply — check the Scottish income tax rates on GOV.UK. Most gigging musicians fall into the basic rate band wherever they are. Let's use a realistic example.

Worked example: a singer earning £28,000 from gigs

Say you earn £28,000 in gross performing income during the 2025/26 tax year. You've tracked your expenses and mileage properly, and they come to £4,200 (£1,800 in mileage, £900 in equipment, £500 in backing tracks and music, £400 in insurance and phone, £600 in marketing and other costs).

Your taxable profit is £28,000 − £4,200 = £23,800.

Income Tax: £23,800 − £12,570 (personal allowance) = £11,230 taxable at 20% = £2,246

National Insurance (Class 4): Self-employed people pay Class 4 National Insurance on profits above £12,570. The rate is 6% on profits between £12,570 and £50,270, then 2% on anything above that.

£23,800 − £12,570 = £11,230 × 6% = £673.80

Total tax and NI: approximately £2,920

That leaves you with about £20,880 from your £28,000 — an effective tax rate of around 12.3%. Not bad. And without claiming those £4,200 in expenses, your tax bill would have been roughly £840 higher.

This is why tracking expenses and mileage properly isn't optional — it directly affects how much of your earnings you keep.

A quick note on Class 2 National Insurance: from April 2024, this is no longer mandatory for most self-employed people. If your profits are above £6,845, you're automatically credited for State Pension purposes without paying anything. If your profits are lower than that, you can choose to pay £3.50 per week voluntarily to protect your pension entitlement.

Payments on account

One thing that catches first-time filers off guard is payments on account. If your tax bill is over £1,000, HMRC will usually ask you to make advance payments towards next year's bill — unless at least 80% of your tax was already collected at source (for example, through PAYE from a day job). These are two instalments — one on 31 January and one on 31 July — each equal to half of your previous year's bill.

It's not extra tax. It's HMRC's way of collecting tax in advance based on the assumption you'll earn roughly the same next year. But it does mean your first Self Assessment payment can feel like a double hit, because you're paying last year's bill plus the first instalment for this year. Budget for it.

Filing your return — step by step

Self Assessment doesn't need to be terrifying. Here's the process, stripped of jargon:

1. Register as self-employed (if you haven't already). You'll get a UTR — a 10-digit number you'll use for all tax correspondence.

2. Keep records throughout the year. Income, expenses, mileage. You don't need to submit receipts with your return, but HMRC requires you to keep records for at least five years after the 31 January submission deadline, so keep everything. A spreadsheet works. An app that tracks it automatically works better.

3. Log in to HMRC's online portal (or use commercial software). The Self Assessment form has a section specifically for self-employment income. You'll enter your total income, total expenses (broken down by category), and your mileage claim.

4. Check the calculation. HMRC will show you what you owe. Review it. If the numbers look wrong, go back and check your figures before submitting.

5. Submit and pay. The deadline for online filing is 31 January following the end of the tax year. So for the 2025/26 tax year (ending 5 April 2026), your return is due by 31 January 2027. You can file earlier — and there's no advantage to leaving it late.

Apps like Gigflow generate tax-year-aligned reports (April to April) that you can export as CSV or PDF for your accountant or to cross-reference with your return. It won't file your return for you, but it means the numbers are already done.

Key dates and deadlines

• 6 April 2025 — 2025/26 tax year starts

• 5 April 2026 — 2025/26 tax year ends

• 5 October 2026 — Deadline to register as self-employed (if you started during 2025/26)

• 31 October 2026 — Deadline for paper tax returns (if anyone still does those)

• 31 January 2027 — Deadline for online Self Assessment filing and payment

• 31 July 2027 — Second payment on account due (if applicable)

Don't wait until January to start gathering your figures. If you've been tracking income and expenses throughout the year, filing takes an afternoon. If you haven't, it takes a weekend of digging through bank statements and trying to remember which gig was where.

What about Making Tax Digital?

From April 2026, HMRC is rolling out Making Tax Digital for self-employed people in stages. If your qualifying income was above £50,000 in 2024/25, you'll need to start keeping digital records and submitting quarterly updates from 6 April 2026. If it was above £30,000, you'll join from April 2027. You'll still file an end-of-year finalisation — it's not replacing Self Assessment entirely, but it does change how and when you report.

I've written a separate guide on what Making Tax Digital means for musicians — it's worth reading now rather than scrambling to understand it in March. The short version: if you're already keeping digital records of your gigs, expenses, and mileage, you're most of the way there.

FAQ

Do I need an accountant as a self-employed musician?

Not necessarily. If your tax affairs are straightforward — performing income, standard expenses, mileage — you can file your own return using HMRC's online system. Many performers do. But if you have multiple income sources, complex expenses, or you'd simply rather have a professional handle it, an accountant is worth the investment. A good one will usually save you more than they cost.

What happens if I don't declare cash payments?

HMRC can usually go back four years, up to six years if they think you were careless, and up to twenty years if they think it was deliberate. If they find undeclared income, you'll owe the tax plus interest and potentially a penalty. It's not worth the risk. Declare everything and claim your expenses properly — that's how you legally reduce your bill.

Can I claim expenses if I also have a day job?

Yes. Your self-employment is assessed separately from your employment income. You claim self-employed expenses against your self-employed income only — they can't be used to reduce the tax on your day job salary. But your personal allowance is shared across both income sources, so be aware that your day job may already use up most or all of it.

How much should I set aside for tax?

A common rule of thumb is 25–30% of your profit (income minus expenses). This covers Income Tax and National Insurance for most basic rate taxpayers. If you're not sure, use HMRC's ready reckoner tool online — it gives you a rough figure based on your estimated profit.

Do I need to register for VAT?

Only if your taxable turnover exceeds £90,000 in a 12-month period. Very few gigging musicians hit this threshold, so it's unlikely to apply. If you're getting close, speak to an accountant before registering — once you're VAT-registered, you'll need to add VAT to your invoices, which can complicate things with agencies.

What's the difference between turnover and profit?

Turnover is your total income from performing before any deductions. Profit is what's left after you've subtracted your allowable expenses. You pay tax on your profit, not your turnover. This is exactly why tracking expenses matters — every legitimate deduction reduces the amount you're taxed on.
