Self-Assessment
Take the dread out of the January tax deadline. Whether you are self-employed, a company director, or earning income from property, our seamless Self-Assessment service ensures your personal tax return is filed accurately and on time.
Service Process
Meticulous preparation and digital submission of your personal tax return.
Ensuring all personal allowances, deductions, and expenses are claimed.
Clear, upfront calculations so you know exactly how much tax to pay and when.
1. What happens if I don’t file my Self-Assessment tax return?
If you miss the deadline, HMRC will issue an automatic £100 penalty, even if no tax is due. Further penalties apply after 3, 6, and 12 months, plus interest on unpaid tax. Continued non-filing can lead to estimated assessments and enforcement action.
2. Do I need to file a Self-Assessment if I am employed full-time?
Yes, if you have any additional untaxed income such as:
• rental income
• dividends or investments
• crypto gains
• side self-employment (Uber, freelancing, etc.)
HMRC does not automatically tax these through PAYE.

3. How do I know if HMRC already has my income information?
HMRC receives data from:
• employers (PAYE)
• banks (interest)
• platforms like Uber, Deliveroo, eBay
• crypto exchanges (increasingly)
However, HMRC does NOT automatically calculate your final tax liability — that is still your responsibility.

7. How long does it take to complete my tax return?
Most returns are completed within 3–7 working days once all documents are provided. Complex cases (crypto, foreign income, property portfolios) may take longer.
8. Will HMRC investigate me if I use an accountant?
No. Using an accountant does not increase your chance of an investigation. In fact, accurate filings reduce risk.
