Driving instructors are self-employed sole traders, so you pay Income Tax and National Insurance on your profit through Self Assessment. Register with HMRC as self-employed, keep records of income and expenses, and file your return and pay by 31 January after the tax year ends. For 2025/26 the first £12,570 of profit is tax-free, then Income Tax is 20% up to £37,700 of taxable income, with Class 4 NI at 6% on profits from £12,570 to £50,270.
This guide walks through registering, the deadlines, payments on account and the current bands. It is general guidance, not tailored advice; for anything complex, speak to an accountant.
Do driving instructors have to pay tax?
Yes. As a qualified ADI you are self-employed, which makes you responsible for calculating and paying your own tax rather than having it deducted at source like an employee. You pay tax on your profit, meaning your turnover minus your allowable business expenses, not on everything you invoice.
That distinction matters. If you turn over £45,000 but have £9,000 of genuine business costs, you are taxed on £36,000, not £45,000. Keeping good records and claiming every allowable expense is therefore not optional admin; it directly lowers your bill. Our allowable expenses guide lists what you can claim as a driving instructor.
How do you register as self-employed?
You register with HMRC for Self Assessment as a sole trader. Do it as soon as you start teaching for payment; the legal backstop is 5 October in the second tax year you trade, but earlier is always better.
When you register, HMRC sends you a Unique Taxpayer Reference (UTR) and sets up your online account, which you use to file returns and pay. You will also be enrolled for Class 2 and Class 4 National Insurance through the same system. Registering late, or not at all, can lead to penalties, so treat it as one of the first jobs when you go on the ADI register. Keep your UTR safe; you will need it every year.
What records do you need to keep?
You must keep records of all your business income and expenses, and keep them for at least five years after the 31 January filing deadline for that tax year. HMRC can ask to see them, and you need them to complete an accurate return.
In practice, that means logging every lesson payment you receive and keeping evidence of every cost you claim (receipts, invoices, mileage logs, bank statements). You do not send these with your return, but you must be able to produce them. This is far easier if you track income and payments as you go rather than reconstructing a year at the deadline. Passly’s finances and expense tracking records lesson income, credits and payments and exports to CSV, giving you and your accountant a clean starting point. Note that Passly tracks your figures; it does not file your return with HMRC.
When are the tax deadlines?
The UK tax year runs 6 April to 5 April. The key deadline is 31 January after the tax year ends: that is when your online return must be filed and any tax paid. Miss it and there is an automatic penalty, even if no tax is due.
| Deadline | What is due |
|---|---|
| 5 October (after you start) | Register for Self Assessment |
| 31 October | Paper tax return deadline |
| 31 January | Online return filed + balancing payment + first payment on account |
| 31 July | Second payment on account |
For the 2025/26 tax year (6 April 2025 to 5 April 2026), you file online and pay by 31 January 2027. Do not leave it to January: filing earlier tells you your bill months ahead, so you can budget for it, while still paying on the deadline.
What are payments on account?
Payments on account are advance instalments towards next year’s tax, and they catch a lot of new instructors off guard. If your Self Assessment bill is more than £1,000, HMRC generally asks you to make two payments on account, each equal to 50% of the previous year’s tax bill.
The first is due on 31 January (alongside your balancing payment for the year just gone) and the second on 31 July. This is why your first January as an instructor can feel brutal: you pay the tax for your first year plus the first 50% instalment towards the next, effectively 150% of your bill in one go. It is not extra tax overall, just paid earlier, and it evens out in later years, but you must budget for it. If your income falls, you can apply to reduce your payments on account, though you should be careful not to underpay.
What are the 2025/26 tax and NI rates?
For 2025/26 in England, Wales and Northern Ireland, the rates below apply to your profit. Scotland sets its own Income Tax bands, so Scottish instructors should check the Scottish rates.
| Band | Rate | Applies to |
|---|---|---|
| Personal Allowance | 0% | First £12,570 of income |
| Basic rate | 20% | Taxable income up to £37,700 |
| Higher rate | 40% | Taxable income £37,701 to £125,140 |
| Additional rate | 45% | Taxable income above £125,140 |
| Class 4 NI (main) | 6% | Profits £12,570 to £50,270 |
| Class 4 NI (upper) | 2% | Profits above £50,270 |
Two extra points for the self-employed: the Personal Allowance tapers away once income tops £100,000 (reduced by £1 for every £2 over), and Class 2 National Insurance is treated as paid once your profits exceed £6,725, so most instructors pay nothing extra for it.

How much should you set aside for tax?
A practical rule of thumb is to set aside 20% to 30% of your profit for tax and National Insurance, moving it into a separate savings account every time a pupil pays you. That way the January bill is already covered.
The right percentage depends on your total profit and which bands it falls into: a part-time instructor well within the basic rate needs to save less than a busy full-timer nudging the higher-rate band. The habit matters more than the exact figure. Instructors who ring-fence tax money as they earn rarely get into difficulty; those who spend everything and hope to find the bill in January often do. Automating a transfer each week makes it painless.
When should you get an accountant?
You are not required to use an accountant, and many instructors file their own straightforward returns. But if your affairs get more complex (buying a car through the business, capital allowances, VAT, taking on other work, or simply wanting peace of mind) a good accountant usually saves more than they cost.
An accountant can make sure you claim everything you are entitled to, handle capital allowances correctly, and keep you the right side of HMRC’s rules. Their fee is itself an allowable expense. If you are ever unsure how a rule applies to your situation, speak to an accountant rather than guessing. This guide gives you the framework; a professional gives you advice tailored to your numbers. Once your record-keeping is in order, Passly keeps your income and payments organised all year, so whether you file yourself or hand it to an accountant, the figures are ready.
