Becoming a teacher is indeed a rewarding job, but it comes with self-employed tax responsibilities. In the UK, teachers must understand tax obligations to pay self-employed teacher tax accurately. Whether you are a teacher or a private tutor, you need to pay tax.
Self-employed teachers have vastly different incomes and are required to pay income tax and National Insurance (NI) on their profits. The tax rules are the same as they are for sole traders.
This guide will clarify aspects of tax for self-employed teachers, tax rates, and tax deductibles for teachers.

Do Teachers Have to File a Tax Return?
In the UK, most teachers are employed, and they pay tax on their income. Teachers pay tax through Pay As You Earn (PAYE), where NI and income tax are automatically deducted from their salaries.
Yes, teachers do not have to file a self-assessment tax return unless they have an extra income and it is more than £1,000 (trading allowance) in a tax year. For instance, if you are earning from private tutoring and your income exceeds £1,000, you must file a self-assessment tax return.
You may be classified as self-employed if you earn extra money by running independent classes or private tutoring. Then, you have to report your income to HM Revenue and Customs (HMRC) to stay tax compliant.

Who Are Self-Employed Teachers?
You are considered self-employed when:
- You run your business for yourself and are responsible for your business’s success and failures.
- You are responsible for supplying your own materials.
- You decide how, where, and when you work
- You have multiple clients
If you are working in a school and meet any of the above criteria, you are a self-employed teacher. Working incorrectly as self-employed can lead to HMRC action to recover unpaid tax.

How Much Tax Does a Self-Employed Teacher Pay?
The tax bill of self-employed teachers consists of income tax and Class 4 National Insurance. Remember, when it comes to self-employed teacher tax, you pay tax on profit, not your total income. The income tax rates and bands for 2024/25 are:

- You pay 20% of tax if your income is between £12,571 and £50,270
- You pay 40% of tax if your income is between £50,271 and £125,140
- You pay 45% of tax if your income is more than £125,141
Moreover, the Small Profit Threshold (SPT) for Class 2 NI contributions is £6,845 as per 2025/26 data. On the other hand, for Class 4 NI contributions, the threshold is £12,570.
Note: The self-employed need to pay NI as it benefits the state and builds entitlement to the state pension.
Are Supply Teachers Self Employed?
Supply teachers temporarily fill vacancies to cover urgent absences in schools for a day or for the long term. Their employment status is a critical consideration.
Generally, if a supply teacher works through an agency and covers for absent staff, they are considered employees, not self-employed individuals. Also, supply teachers operate through an umbrella company or PAYE, and they do not need to worry about the self-Employed Teacher Tax.
