Self Assessment Tax Returns
We prepare, check and file your Self Assessment tax return with HMRC before the deadline. It is accurate, stress-free and makes sure no allowances are missed.
What our Self Assessment service covers
A Self Assessment tax return takes time to get right, and mistakes or missed deadlines can cost you in penalties. Whether you are self-employed, a landlord, a director or a higher earner, we take the return on and make sure it is correct.
We gather what we need, prepare the return, claim everything you are entitled to and file it with HMRC. Then we tell you clearly what to pay and when.

How we help with your Self Assessment
We make Self Assessment simple. Send us your information and we handle the rest: checking for allowances and reliefs you might otherwise miss, working out your bill accurately, and filing well ahead of the deadline, so you are never caught short.
Key Self Assessment deadlines
For a typical tax year, the deadline for paper returns is 31 October and for online returns 31 January. Any tax owed is normally due by 31 January, with payments on account where applicable. These figures reflect the position as of October 2026 (2026/27 tax year) and can change at future fiscal events. Always confirm current rates, thresholds and deadlines on GOV.UK or ask us before acting.

Common questions about Self Assessment
Common reasons include being self-employed, receiving rental income, being a company director with untaxed income, having significant savings or investment income, or being a higher earner. If you are unsure, we can check whether you need to file.
Online returns and any tax due are generally due by 31 January following the end of the tax year, with paper returns due earlier by 31 October. We file well ahead of time.
These are advance payments towards your next tax bill, usually required where your liability is above a certain level. We calculate them and explain how they affect your cash flow.
