Self Assessment Tax Returns made simple
If HMRC expects a tax return from you, it has to be right and it has to be on time. Our accountants prepare and file your Self Assessment tax return, check you've claimed every allowance and expense you're entitled to, and tell you exactly what to pay and when — well before the 31 January deadline.
We work with sole traders, company directors, landlords, people with investment or foreign income, and anyone who has received a letter from HMRC asking them to file. Whether it's your first return or you're catching up on several years, we'll make it straightforward.
What's included
- Preparation and online filing of your SA100 tax return
- Self-employment, rental, dividend, savings, foreign and capital gains income
- Review of allowable expenses and reliefs to reduce your bill
- Payments on account checked and explained
- HMRC correspondence handled as your authorised agent
- Making Tax Digital for Income Tax set-up and quarterly updates
Who it's for
Sole traders, landlords, company directors, higher earners, people with side income and anyone HMRC has asked to file. We regularly help sole traders, e-commerce & online sellers, doctors, dentists & locums, tradespeople & CIS.
What we'll need from you
Getting started is straightforward. Typically we'll ask for:
- Your UTR number and Government Gateway details (or we can register you)
- P60/P45 and any P11D from employment
- Income and expense records for self-employment or property
- Bank interest, dividend and pension statements
- Details of any assets sold during the year
Don't worry if something's missing — we'll tell you exactly what's needed and help you find it.

Self Assessment Tax Returns FAQs
When is the Self Assessment deadline?
Online tax returns must be filed by 31 January following the end of the tax year on 5 April, and any tax owed is due the same day. A second payment on account, if you make them, is due by 31 July.
Do I need to file a Self Assessment tax return?
You'll usually need to file if you're self-employed, receive rental income, are a company director taking dividends, have untaxed income over certain limits, earn over the High Income Child Benefit Charge threshold, or have capital gains to report. We can confirm this for you.
What happens if I file my tax return late?
HMRC charges an automatic £100 penalty for a late return, with further daily and percentage-based penalties the longer it remains outstanding, plus interest on late payment. We can help bring overdue returns up to date and appeal penalties where you have a reasonable excuse.
