Keeping your music teaching income ready for Self Assessment

The tax year runs 6 April to 5 April

This is the first thing that trips up a teacher moving from PAYE, because it matches neither the calendar year nor the school year. Your teaching year runs September to July; your tax year runs 6 April to 5 April and cuts straight through the summer term.

The practical effect is that a single academic year is split across two tax returns, and the split falls in the middle of exam season and summer invoicing. A term you taught in March and a term you taught in May sit in different tax years even though they are the same cohort, the same rate, and quite possibly the same invoice if you bill termly. Record income by the date it was received, and the split takes care of itself.

The £1,000 trading allowance, and when you must register

If your gross teaching income for a tax year is £1,000 or less, the trading allowance covers it and you do not need to register for Self Assessment or report it. This is genuinely useful for a teacher with two or three students alongside a day job.

Once gross income passes £1,000 you must tell HMRC, and the deadline is 5 October following the end of that tax year. Note that the test is on gross income, not profit: £1,400 of tuition with £600 of expenses is still over the threshold, even though the profit is not.

You can also choose to claim the £1,000 allowance instead of deducting your actual expenses, which is worth doing in any year your real expenses came to less than £1,000. You cannot do both. A teacher with £3,000 of income and £400 of expenses is better off taking the allowance.

VAT: private music tuition is usually exempt

Generic self-employment advice tells you to watch the £90,000 VAT registration threshold. For a private music teacher that advice is usually beside the point, and it is worth understanding why.

Private tuition in a subject ordinarily taught in a number of schools or universities is exempt from VAT when it is supplied by a sole proprietor or a partner in a partnership. Music is plainly such a subject, so one-to-one and small-group music lessons from a sole trader are exempt supplies.

That matters twice over. You do not charge VAT on those lessons — and exempt turnover does not count toward the £90,000 threshold, which is measured on taxable turnover only. A sole trader teaching £95,000 of lessons has not missed a registration deadline.

Two conditions do real work here, and both catch people out. The exemption is tied to the individual teaching: a limited company cannot supply exempt private tuition, so incorporating your studio changes the VAT answer. And if you grow by taking on other teachers, the lessons you personally deliver stay exempt while the lessons your employees deliver are standard-rated — at which point you have a mixed business and a threshold that suddenly matters.

Things sold alongside tuition are a separate question. Selling instruments, books or merchandise is a taxable supply and does count toward the threshold.

National Insurance, which is not the same as your tax bill

Self-employed National Insurance comes in two classes and is settled through the same Self Assessment return, which is why it tends to arrive as a surprise on top of the income tax you were expecting.

Class 4 is the one most teachers pay: 6% on profits between £12,570 and £50,270, and 2% on profits above £50,270 (2026-27 rates). Class 2 is no longer charged in the way it once was — if your profits are at or above £7,105 your record is treated as though Class 2 had been paid, and below that you can pay voluntarily at £3.65 a week to protect entitlement to the State Pension and other contributory benefits.

That voluntary option matters more than its size suggests. A teacher with a small studio and a gap year can lose a qualifying year on their NI record for the sake of about £190, and will not find out until decades later.

What you can claim

The test is that the expense is wholly and exclusively for the business. Where something is used privately as well, you claim only the business proportion, on a basis you could explain.

• Instruments and equipment. A piano, amplification, recording gear or an iPad for scores is normally a capital item claimed through capital allowances rather than as a running cost — the Annual Investment Allowance usually lets you claim the full cost in the year of purchase, which is a different answer from most other countries.
• Tuning, servicing, strings, reeds and repairs. Ordinary running costs, claimed in full.
• Sheet music, method books, exam entry fees you pay and are not reimbursed for, and licence fees.
• Working from home. You can either apportion your actual costs (rent, mortgage interest, council tax, utilities, insurance) by rooms and time used, or use HMRC's simplified flat rate based on hours worked from home each month. The flat rate is less generous but far less argument.
• Travel to teach. Mileage to a pupil's home or a school you visit. Simplified mileage rates are the usual approach for a car. Travel between home and a single regular place of work is commuting and is not allowable.
• Software and subscriptions. Studio management, notation software, video lesson platforms, accounting tools, website and domain.
• Professional costs. Association membership (ISM, MU, EPTA and similar), insurance, DBS checks, continuing professional development.
• Payment and bank charges on tuition you collect.

Deadlines and payments on account

The date most teachers know is 31 January. The one that does the damage is 31 July.

If your Self Assessment bill is more than £1,000, HMRC asks for payments on account towards next year's bill: two payments, each half of last year's tax, due 31 January and 31 July. The exception is if more than 80% of your tax was already deducted at source — relevant if you also have a PAYE job.

So a first profitable year does not produce one bill. It produces last year's tax plus the first payment on account, both on 31 January, which in practice means around 150% of what the teacher had budgeted for. Then a second payment lands in July, out of term, when tuition income is at its lowest point of the year. This is the single most common cash-flow failure in a private teaching practice, and it is entirely predictable.

• 5 October — deadline to register for Self Assessment, following the end of the tax year in which you passed £1,000.
• 31 October — deadline for a paper return.
• 30 December — file online by this date if you want tax under £3,000 collected through your PAYE tax code.
• 31 January — online filing deadline, payment of the balance, and the first payment on account.
• 31 July — second payment on account.

A worked example: a studio of 20 pupils

Twenty weekly pupils at £30 a lesson across a 36-week teaching year is £21,600 of scheduled tuition. Assume £700 was lost to families who left mid-term without paying notice. Gross income is £20,900.

On £16,963 of profit, Class 4 NI is 6% of the amount above £12,570 — about £264 — and that sits on top of income tax. Because the total bill here is likely to be over £1,000, the following 31 January brings the bill plus a payment on account of half of it again.

The digital piano is claimed in full under the Annual Investment Allowance, which is why the profit in a year you buy an instrument can look artificially low and the following year artificially high. Plan the July payment on account around that, not around the profit you last saw.

Keeping records

You must keep your records for at least five years after the 31 January submission deadline for the relevant tax year. In practice that means a 2026-27 return, due 31 January 2028, needs its records until early 2033.

The records that go missing are almost never the invoices. They are the bank-transfer receipts that say only a parent's name and an amount, the cash a pupil handed over at the door, and the mileage that was never written down at the time. Capture what a payment was for when it arrives, and the return becomes transcription rather than reconstruction.

How it works

1. 1Invoice from your lessons through the year and record each payment against its invoice so income is captured as you earn it.
2. 2Scope billing and reporting to the UK tax year — Note & Key uses the 6 April–5 April boundaries automatically.
3. 3Export a tax-year income summary labelled for the self-employment pages (SA103) to use for Self Assessment or pass to your accountant.
