This is an estimate using HMRC-confirmed rates for 2026/27, not your official tax calculation. TapTax is MTD-compatible, so you can connect to HMRC and file the real figures in a couple of taps.
- Tutoring is a low-overhead trade, so for most tutors the tax due is driven by income tracking rather than expenses: every cash lesson, bank transfer and platform payout must be captured.
- If your tutoring income tops £1,000 you must register for Self Assessment; below that the trading allowance covers you, and you can deduct the flat £1,000 instead of expenses if it gives a lower profit.
- Private one-to-one tuition in a school subject is generally VAT-exempt, so a solo maths tutor usually never charges or registers for VAT whatever the turnover.
- Many tutors also hold a PAYE teaching job, so the personal allowance is often already used and tutoring profit is taxed from the basic rate up.
- MTD for Income Tax applies from April 2026 above £50,000, April 2027 above £30,000, and April 2028 above £20,000, tested on gross income not profit.
The tax picture for a self-employed maths tutor is refreshingly simple on the expenses side and surprisingly easy to get wrong on the income side. Overheads are tiny: a laptop, some textbooks, a subscription or two and a corner of a spare room. The trap is the income itself. A typical tutor might take cash for a Tuesday evening session, a bank transfer from one parent, a card payment through a tutoring platform that pays out weekly minus a fee, and a lump sum for a block of half-term revision sessions. Money lands in several places at irregular times, and the temptation to treat the odd cash lesson as invisible is exactly what gets tutors into difficulty with HMRC.
This guide is built around how tutors actually earn: the trading allowance for those starting out, the handful of genuinely allowable costs, the VAT exemption that means most tutors never touch VAT at all, and how a tutoring trade sits alongside a teaching salary. Capture every lesson fee as it comes in and the annual return becomes a formality.
How Tax Works for a Self-Employed Tutor
As a sole trader you pay Income Tax on profit, which is your total tutoring income minus allowable expenses. For 2026/27 the personal allowance covers the first £12,570, then you pay 20% to £50,270, 40% to £125,140 and 45% above, with the personal allowance tapering away between £100,000 and £125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between £12,570 and £50,270 and 2% above, with Class 2 NIC settled through Self Assessment.
Scottish tutors pay Scottish Income Tax on their profit through six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, while National Insurance stays UK-wide. Welsh tutors have a C-coded tax code at rates currently matching the rest of the UK. If your code looks wrong, often because a teaching salary or other PAYE work is distorting it, run it through the tax code checker.
The Trading Allowance and Starting Out
Almost every tutor begins as a side hustle: a teacher taking on a couple of evening students, a graduate building a client base, a retired educator helping local families. The £1,000 trading allowance is built for exactly this. If your gross tutoring income from all sources is £1,000 or less in a tax year, it is tax-free and you do not need to register for Self Assessment for it. Cross £1,000 and you must register and report the full amount, not just the bit above the threshold.
Once you are over the line you have a choice each year. You can deduct the flat £1,000 trading allowance from your income instead of working out actual expenses, which suits a tutor with almost no costs. Or you can deduct your real allowable expenses if they come to more than £1,000. You cannot do both, so total your costs and pick whichever leaves the lower profit. A tutor working online from a laptop they already owned often does better claiming the £1,000; one who bought a new device, a graphics tablet, exam packs and pays platform commission usually does better claiming actuals. Our guide to side hustle income covers the threshold in more detail for tutors juggling other work.
Allowable Expenses for Maths Tutors
An expense is allowable when it is incurred wholly and exclusively for the business. A tutor's list is short but worth claiming in full where the costs are real.
| Expense | What qualifies | Notes |
|---|---|---|
| Teaching resources | Textbooks, GCSE and A-level workbooks, past papers, printed worksheets, manipulatives | Must relate to subjects you teach |
| Computer and devices | Laptop, tablet, second monitor, webcam, headset for online lessons | Usually claimed in full via the Annual Investment Allowance |
| Graphics tablet and stylus | Writing equations on screen for online tutoring | Genuinely business kit for a maths tutor |
| Whiteboard and stationery | Whiteboard, pens, paper, printer ink and printing | Fully deductible consumables |
| Software and platforms | Tutoring marketplace fees, video calling, interactive whiteboard, lesson-booking subscriptions | Subscriptions and commission are deductible |
| Home-office costs | HMRC flat-rate working-from-home allowance, or a fair proportion of heat, light, broadband, rent or mortgage interest | Choose the larger fair deduction |
| DBS check | Enhanced disclosure for working with children | Allowable where required for the trade |
| Professional membership | The Tutors' Association or relevant subject bodies | Allowable where relevant to tutoring |
| Advertising | Listing fees, flyers, website, social posts to find students | Fully deductible marketing |
| Travel and mileage | Driving to students' homes or a hired room | 45p per mile for the first 10,000 business miles, then 25p |
| Training and CPD | Courses updating your existing subject or teaching skills | Training into a brand-new trade is not allowable |
| Accountancy and bank fees | Bookkeeping, Self Assessment, business banking | Fully deductible |
Home-Office and Travel in Detail
Most tutors teach either online from home or in person at the student's house, so the two costs that matter most are home-office running costs and mileage. For home working you can use HMRC's simplified flat rate based on the hours you work at home each month, which needs no receipts, or claim an actual proportion of household running costs (heat, light, broadband and a share of rent or mortgage interest) based on rooms used and time spent. Do the sum both ways once and use the larger result.
For in-person tutoring, mileage to and from a student's home is allowable at 45p per mile for the first 10,000 business miles in the year, then 25p, provided you keep a simple log of dates, destinations and distances. The catch is the line between business travel and ordinary commuting: travelling to a regular fixed place you treat as your base can be caught as non-allowable commuting, so most tutors are safer claiming each trip to a student as the business journey it is and keeping the record to prove it.
What You Cannot Claim
The private share of dual-use broadband, phone and a family laptop must be excluded. Everyday clothing is never allowable. A maths degree or initial teacher training that qualified you in the first place is not deductible because it created the skill rather than maintaining it. And ordinary commuting, plus any lunch you buy on a normal working day, falls outside the rules.
Worked Example: A Maths Tutor on £28,000
Take a tutor running a mix of online GCSE and A-level maths sessions plus a few in-person students, billing £28,000 of fees across the year.
Income: £28,000 (online lessons £19,000, in-person lessons £6,000, half-term revision courses £3,000)
Allowable expenses:
- Laptop, graphics tablet and webcam (AIA, claimed in full): £900
- Textbooks, past papers and printed worksheets: £350
- Tutoring platform commission and software subscriptions: £1,400
- Home-office actual-cost proportion: £1,100
- Mileage to in-person students (1,200 miles at 45p): £540
- DBS check and professional membership: £110
- Accountancy fees: £300
- Total expenses: £4,700
Taxable profit: £28,000 minus £4,700 = £23,300
Income Tax: £23,300 minus £12,570 = £10,730 at 20% = £2,146
Class 4 NIC: £10,730 at 6% = £644
Total tax and NIC: £2,790 for the year. This assumes the tutoring is the only income and the full personal allowance is available. A tutor who also draws a teaching salary would have that allowance used up by the job, so every pound of this profit would be taxed from the basic rate up. Run your own figures through the sole trader tax calculator to check, and the multiple-income calculator if you also have a salary.
For a tutor, the money you forget to record costs more than any expense you forget to claim. Log every lesson, cash payment and platform payout as it lands, and the return writes itself.
Tutoring Alongside a Teaching Job
A large share of tutors also teach in a school, which means two income types on one tax return. Your salary is taxed under PAYE and your personal allowance is usually applied through your tax code against that job. Your tutoring is a separate self-employed trade. Because the £12,570 allowance is typically already used by the salary, your tutoring profit is generally taxed from the basic rate up, and at 6% Class 4 NIC on top, so a sensible rule of thumb is to set aside 25 to 30 percent of tutoring profit for the tax bill.
- Trading allowance
- A £1,000 tax-free allowance for casual or self-employed income. If your gross self-employed income for the year is £1,000 or less, it is tax-free and you do not need to register for Self Assessment for it. If you go over £1,000 you must register and report all of the income, then choose to deduct either the flat £1,000 allowance or your actual allowable expenses, whichever produces the lower taxable profit. You cannot claim both the allowance and actual expenses on the same income.
The common error here is assuming the first slice of tutoring income is tax-free because everyone gets a personal allowance. The allowance is one per person across all income, and if PAYE has already absorbed it, there is none left for the tutoring trade.
VAT for Tutors: Usually Nothing to Do
This is the area where tutors get good news. Private tuition in a subject ordinarily taught in a school or university, given by a sole proprietor or a partner teaching personally, is exempt from VAT under the private tuition exemption. A self-employed maths tutor teaching GCSE, A-level or undergraduate maths is squarely within this. In practice that means you do not charge VAT on your lessons and you do not register for VAT, regardless of how high your turnover climbs, so the £90,000 registration threshold that bites other trades simply does not apply to your tuition income.
The nuance is who is doing the teaching. The exemption attaches to the individual teaching in person. If you grow into an agency that engages other tutors and bills clients for their lessons, that supply is treated differently and the standard VAT rules can apply to the agency fee. A solo tutor teaching their own students has nothing to worry about; one building a tutoring business with a roster of staff should take advice before assuming the exemption still covers everything.
MTD for Income Tax: What Changes for Tutors
Making Tax Digital for Income Tax Self Assessment replaces the once-a-year return with quarterly digital submissions and a year-end finalisation. The thresholds are based on gross income, not profit:
- April 2026: Combined trading and property income over £50,000
- April 2027: Over £30,000
- April 2028: Over £20,000
For a tutor the practical shift is habit. Instead of reconstructing a year of lesson payments from memory, bank statements and a platform dashboard each January, you record each lesson fee digitally as it is paid and send HMRC a quarterly summary using compatible software. Given how scattered tutoring income is across cash, transfers and marketplace payouts, the continuous record is the part that actually saves you stress. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.
Common Mistakes Maths Tutors Make
Not declaring cash lessons. A cash payment for a Tuesday evening session is taxable income exactly like a bank transfer. Treating cash as invisible is the single most common and most serious tutoring error.
Missing the £1,000 registration trigger. The trading allowance is a threshold, not a free pass at any level. Once gross tutoring income tops £1,000 you must register for Self Assessment, even if you also have a salaried job.
Forgetting platform fees and commission. Marketplace and booking platforms often pay you net of their cut. Record the gross fee as income and claim the commission as an expense so your figures reconcile.
Assuming the teaching salary's allowance covers tutoring. If PAYE has used your personal allowance, your tutoring profit is taxed from the basic rate up, so set aside more than you might expect.
Claiming the original qualification. The degree or teacher training that qualified you is not allowable; only training that updates skills you already use in the trade can be claimed.

Quarterly expenses under MTD: the £90,000 rule
If your annual business turnover is £90,000 or less, HMRC lets you report a single consolidated expenses total in each Making Tax Digital quarterly update instead of breaking expenses down into itemised categories. Most self-employed maths tutor businesses are under this threshold, so a quarterly update can be as simple as two figures: total income and total expenses. You still need to keep digital records of each individual expense - the relaxation only changes how much detail goes into the quarterly update itself.
