What Is a Self-Assessment Tax Return?
It’s the method HMRC uses to collect income tax from individuals and businesses whose tax isn’t automatically deducted, such as self-employed professionals, landlords, and company shareholders. You’re required to file one if you:
- Are self-employed or a sole trader
- Receive rental income
- Earn dividends or investment income
- Are a company director
- Have other untaxed income
The return includes details about your income, expenses, tax already paid, and what you owe. It must be submitted annually, and errors or missed deadlines can result in fines.
That’s where Brywel Associates comes in, taking the pressure off and ensuring your tax filing is timely, correct, and maximised to your benefit.
Our Services for Self-Assessment Tax Returns Include:
- Completion and submission of your HMRC tax return, including income, expenses and taxable profit
- Guidance on available tax relief and allowable deductions
- Liaising with HMRC on your behalf, including any follow-up questions
- Tailored advice for sole traders, landlords, and limited company directors
- Digital filing compliant with Making Tax Digital regulations
- Support for accounting systems such as Sage, Xero, and QuickBooks
- Integrated assistance with your bookkeeping, payroll and VAT returns if needed
Whether you’re behind on last year’s return or want to get ahead for the next deadline, our team is ready to help.

How We Help You Maximise Tax Relief

We’ll help you:
- Claim the correct proportion of home office or vehicle expenses
- Include pension contributions, charitable donations, or investment relief
- Avoid overpaying on income that qualifies for tax-free thresholds
We don’t just fill out forms; we ensure you get the best result possible.
Who needs to complete self-assessment tax returns?
Anyone who earns untaxed income, such as self-employment, rental properties, dividends, or freelancing, must submit a return. Company directors may also need to file one, even if they don’t take a salary.
What documents do I need to provide?
We’ll need details of all your income, expenses, P60s or P45s (if applicable), bank statements, and supporting invoices or receipts. We can also work directly with your digital records if you use software like Xero, Sage or QuickBooks.
Can you help if I’ve missed the tax return deadline?
We can help you file late, manage penalties, and get back on track for future submissions.
Do you offer HMRC support if they ask questions about my return?
Absolutely. We liaise directly with HMRC on your behalf and offer Fee Protection Cover in case of formal investigations.
