Self Assessment Accountant in Richmond

Your Self Assessment tax return prepared, checked and filed by a local accountant in Richmond — fixed fee from £150, no surprises in January.

If you're looking for a Self Assessment accountant in Richmond, I can take the whole thing off your plate. I'm Marcin Rusiecki, an accounting and finance graduate and a tax agent who deals with HMRC for you based right here in Richmond, London (TW9). I prepare, check and file Self Assessment tax returns for employed people, landlords and the self-employed — with the fee agreed in writing before any work begins.

HMRC has told you to file, or you know you need to — but the forms, the allowances and the deadlines are someone else's specialty. That's exactly what I do, and once you authorise me as your agent, we deal with HMRC for you, so you don't have to.

Who this service is for

Employed (PAYE) with extra income

You have a P60 plus a side gig, dividends, savings interest or foreign income — and HMRC wants a return.

Landlords

Rental income from a property in Richmond or anywhere in the UK — with every allowable cost properly claimed.

Self-employed & freelancers

Sole trader income and business expenses — if you need accounts too, my Sole Trader package covers both from £200.

First-time or late filers

Never filed before, or missed previous years? I can help with late and first-time returns — filing now is always better than waiting.

What's included — from £150, fixed fee

The Self Assessment deadline is 31 January. Returns filed late mean automatic HMRC penalties — starting at £100 even if you owe no tax. Send your documents early and your return is typically ready within 3–7 working days.

Based in Richmond — for clients anywhere in the UK

I'm based in Richmond (TW9), so if you're in Richmond, Twickenham, Kingston, East Sheen or anywhere in south-west London, you're dealing with a genuinely local accountant. Everything can also be done fully remotely — documents by email, signatures online — so wherever you are in the UK, the process is the same: simple, fixed-fee and on time. I also speak Polish — mówimy po polsku.
