Income Tax Return in England (Self Assessment)
We handle your personal tax return with accuracy and confidence.

What is Self Assessment in the UK?
Self Assessment is the system used by HMRC for individuals to report their income tax.
If you are self-employed, a company director, receive rental income, dividends, or have any income outside the PAYE system, you must file an annual tax return with HMRC.
Unlike some countries, in the UK the responsibility for submitting the return lies entirely with the taxpayer, and any mistakes can result in penalties and interest. That’s why working with an experienced accountant is essential.
Who needs to file a Self Assessment tax return in the UK?
You must file if, in the last tax year (6 April to 5 April), you:
- Worked as a self-employed individual
- Served as a director of a Limited Company
- Received rental income
- Earned profits from investments or dividends
- Received income from abroad
- Earned over £100,000 in the year
- Were requested by HMRC to file a return
What does the income tax return process involve?
The process includes:
- Gathering and organising all income and expense documents
- Correct calculation of taxable income
- Completing the full Self Assessment tax return
- Submitting the return by the deadline (31 January)
- Paying any tax owed
Filing errors, late submissions, or income omissions may lead to automatic fines.

Frequently Asked Questions (FAQ)
When is the Self Assessment deadline?
The final deadline is 31 January following the end of the tax year (6 April to 5 April).

Yes. If you are registered as self-employed, you must file a tax return, even if you earned little or nothing.
Can I receive a tax refund?
Yes. If you have paid more tax than you owe during the year, you may be entitled to a refund. We handle these calculations for you.
Can I file on my own through the HMRC website?
Yes, you can file yourself, but errors in completion or submission are common. An accountant helps avoid issues and ensures your tax affairs are secure.
