Private Tutoring Side Income Tax — A UK Guide for 2026/27
Whether you tutor a few hours a week alongside a full-time job or run a growing tutoring business, here's how UK tax applies to private tutoring income in 2026/27.
Combining Employment and Self-Employment Income
Many tutors are also employed elsewhere — teachers tutoring in the evenings, graduates tutoring alongside a full-time job, or parents tutoring around other work. The key principle to understand is that your Personal Allowance and Income Tax bands apply to your total income across all sources combined, not separately to each source. This means tutoring income is effectively taxed "on top of" your employment income, at whatever marginal rate applies once your combined income is totalled.
| Combined income scenario | Effective tax rate on additional tutoring income |
|---|---|
| Employment income already uses full Personal Allowance, combined total stays within basic rate | 20% |
| Combined total pushes into higher-rate band | 40% on the portion above £50,270 |
| Combined total exceeds £100,000 | Personal Allowance taper may also apply, increasing effective rate further |
The £1,000 Trading Allowance for Occasional Tutoring
If your tutoring is genuinely occasional and gross income stays under £1,000 a year, the trading allowance means no registration or declaration is needed. Above £1,000, Self Assessment registration is required, with a choice between deducting the £1,000 allowance or your actual allowable expenses (whichever produces a better outcome) against your tutoring income.
Allowable Expenses for Tutors
- Travel to pupils' homes: mileage (45p/mile up to 10,000 miles, 25p thereafter) or actual public transport costs
- Teaching materials and resources: books, worksheets, subscriptions to educational platforms
- DBS check costs: generally allowable as a cost incurred for the business
- A proportion of home costs: if you tutor pupils at your own home, a reasonable proportion of relevant household costs
- Professional development: courses or qualifications directly relevant to your tutoring subject
Online Tutoring: A Slightly Different Expense Profile
Tutors working online rather than travelling to pupils' homes have a different expense profile — travel costs largely disappear, replaced by costs like video conferencing software subscriptions, a reliable internet connection (proportionate business use), and any online tutoring platform fees, all of which are similarly allowable if genuinely incurred for the business.
Registering and Filing
Once registration is required, tutoring income (alongside any other self-employment income) is declared through Self Assessment, due by 31 January following the end of the relevant tax year for online filing, with any tax owed on top of what has already been correctly deducted from employment income via PAYE.

Frequently asked questions
I'm a full-time employed teacher who tutors privately in the evenings — how is this taxed?
Your tutoring income is treated as self-employment income, entirely separate from your employed teaching salary, and is taxed additionally on top of your employment income once combined income pushes into higher tax bands. You'll need to register for Self Assessment (if not already registered) and declare tutoring income above the £1,000 trading allowance, with the tax rate applied depending on your total combined income from both sources.
Does tutoring income affect my Personal Allowance if I already use it all against my main salary?
Yes, effectively — the £12,570 Personal Allowance is a single allowance across all your income sources combined, not a separate allowance per job or income type. If your employed salary already uses your full Personal Allowance, additional tutoring income is taxed starting at your marginal rate (commonly 20% or 40% depending on your total income), with no further tax-free amount available specifically for the tutoring income.
Can I claim travel costs for tutoring pupils at their homes?
Yes, generally — mileage or public transport costs for travelling to pupils' homes for tutoring sessions are typically an allowable business expense, using either actual costs or the standard HMRC mileage rate (45p per mile for the first 10,000 business miles in a tax year, 25p thereafter, for a car) if you keep a mileage log. Travel from your home to a regular single tutoring location might be treated differently from travel between multiple different pupils' homes — the specific pattern matters.
Do I need a DBS check for tax purposes as a tutor?
No — a DBS (Disclosure and Barring Service) check relates to safeguarding requirements, often expected or required by parents, schools or tutoring agencies, and is entirely separate from tax registration requirements. The cost of obtaining a DBS check specifically for your tutoring business is, however, generally an allowable business expense for tax purposes, since it is a cost incurred wholly for the business.
