Self Assessment tax return service

We calculate, optimise and file Self Assessment tax returns for UK sole traders, company directors, landlords and higher earners — every allowable expense claimed, filed before the 31 January deadline.

Who needs to file a Self Assessment?

You generally need to file if you’re self-employed, a company director, a landlord, a higher earner, or have untaxed income. The online return and any tax due are filed by 31 January, with a second payment on account due 31 July. Miss it and HMRC charges an automatic £100 penalty even if no tax is owed.

We handle the whole thing — gathering your figures, claiming every expense and relief, and telling you exactly what to pay and when.

File early, sleep easy

Filing early doesn’t mean paying early — it just means you know your bill by Christmas instead of panicking in January. We file ahead of the deadline so you can budget with confidence.

Online returns and any balancing tax are due by 31 January; a second payment on account (if applicable) is due 31 July. We file early so you're never caught out.

For sole traders it's included in your monthly plan from £45. One-off returns are also available — get a quote for your exact price.

We can still file quickly to limit penalties and interest, and help you appeal if you have a reasonable excuse.
