Self Assessment for musicians: the plain-English guide
If you earn money from music outside PAYE, gigs, DJ sets, teaching, royalties, merch, production work, Self Assessment is how you declare it. Here is the whole shape of it, in plain English.
Do you need to file at all?
If your gross self-employment income (money in, before any expenses) was more than £1,000 in the tax year, you need to register and file. Under £1,000, the trading allowance usually covers it and you may not need to file for that income at all, though registering can still be worth it if you made a loss or want to pay voluntary National Insurance. The tax year runs 6 April to 5 April.
The dates that matter
- 5 October: deadline to register for Self Assessment for the tax year that ended the previous April, if you have not filed before.
- 31 January: online filing deadline and the day the tax is due. This is the January everyone means.
- 31 October: the earlier deadline if you file on paper.
- 31 July: the second payment on account, if payments on account apply to you.
Payments on account catch people out: once your bill is over £1,000, HMRC asks for advance payments towards next year, half in January and half in July. The first year this happens, you effectively pay one and a half years of tax at once. Budget for it.
What counts as income
All of it. Gig and set fees, teaching, session work, production and mixing, royalties from PRS and PPL, distributor and Bandcamp payouts, merch, Patreon, sync fees, tips. Cash counts exactly like a bank transfer, and money that arrived through PayPal or a card reader is still income. Where a platform deducted its fee before paying you, the usual position is that the full amount is your income and the fee is a business expense, which keeps your turnover honest.
The expenses musicians actually claim
You pay tax on profit, not turnover, so expenses matter. In musician terms, the common ones:
- Equipment and instruments: decks, controllers, interfaces, mics, cables, repairs and insurance.
- Travel: trains and mileage to gigs, sessions and rehearsals, plus accommodation for out-of-town shows.
- Software and subscriptions: your DAW, plugins, Splice, sample libraries, website hosting.
- Fees and commission: agent and manager cuts, PayPal and card-reader fees, platform commission.
- Phone, internet and home studio: the business share of bills, not the whole thing.
- Promotion: ads, photos, videos, press.
The rule of thumb is "wholly and exclusively" for the business, with mixed-use items claimed at a fair business share. Alternatively, if your expenses are tiny, you can claim the flat £1,000 trading allowance instead of itemising, but never both.
What filing actually involves
For most musicians it is the main return plus the self-employment pages (SA103), which want your income and expenses summarised into set categories. That mapping, from a year of messy bank statements into SA103 boxes, is the real work of Self Assessment, and it is exactly the part software should do for you.

Keep the statements, invoices and receipts behind your figures for at least five years after the filing deadline. A digital record with the paper trail attached beats a shoebox every time HMRC has a question.
Common questions
I have a day job and gig on the side. Do I need to file?
If the gigging side grossed more than £1,000 in the tax year, yes: register by 5 October and file, with your PAYE job going on the employment pages of the same return. Under £1,000 gross, the trading allowance usually means no return is needed for that income.
Do I have to declare cash gigs?
Yes. Cash income is taxed identically to bank transfers, and unexplained deposits are exactly what HMRC enquiries dig into. Record cash gigs as they happen and the question never arises.
Do I report what a platform paid me, or the amount before its fees?
Where you were entitled to the full amount and the platform took its cut before paying out, the usual position is gross income and the fee as an expense. Your profit is the same either way, but turnover-based thresholds care about the difference. If in doubt, ask your accountant.
What records do I need for my first return?
Your bank statements for the tax year, a note of any cash income, receipts for expenses, and your registration details (UTR). If you sort the statements into income and expense categories first, the return itself is mostly copying totals into boxes.
