How to use this tutor tax calculator uk
Use this tutor tax calculator to estimate UK tax on private tutoring income, online tutoring, coaching or exam-prep work alongside PAYE employment.
Enter tutoring income before expenses, then model allowable costs such as platform fees, teaching materials, travel, software or the trading allowance.
Tutoring income is commonly self-employed trading income unless it is paid through PAYE. Keep records of students, sessions, platform statements and expenses.
- Use Side Hustle Income for gross income before expenses or allowances.
- Use Side Hustle Expenses for allowable expenses, or for the deduction you want to model, such as the trading allowance.
- Use Annual Salary for your PAYE salary before tax.
Trading Allowance vs Actual Expenses
The trading allowance can exempt up to £1,000 of gross trading income. If your gross trading income is £1,000 or less, you may not need to tell HMRC, although some circumstances still require a tax return.
If gross trading income is more than £1,000, you can usually choose between deducting the £1,000 trading allowance or deducting actual allowable expenses. You cannot claim both for the same trade.

FAQs
Do tutors need to pay tax in the UK?
Private tutors may need to pay tax if tutoring income is taxable trading income. PAYE salary and tutoring profit are considered together for Income Tax.
When should a tutor register for Self Assessment?
You normally register if gross tutoring income is over £1,000 in a tax year or if HMRC otherwise requires a tax return.
What expenses can private tutors claim?
Allowable costs may include teaching materials, platform fees, software, business-use phone or internet, and travel where they are incurred for the tutoring trade.
Can I claim DBS checks, travel or materials?
Business-related checks, travel and materials may be allowable where they are necessary for your tutoring work and not private costs.
Does PAYE income affect tutoring tax?
Yes. Your tutoring profit is added to PAYE income, so the marginal tax rate depends on your combined taxable income.
Can tutors use the trading allowance?
If eligible, you can use the £1,000 trading allowance instead of actual expenses for the same trade. If actual expenses are higher, modelling actual costs may be better.
