Self Assessment

Self Assessment tax returns for sole traders, directors, freelancers, landlords and other self-employed individuals, with consideration of allowable expenses and available reliefs.

Overview

How we help with Self Assessment

Self Assessment catches out more people than any other part of the UK tax system. We prepare and file your return, tell you exactly what you owe and when, and make sure you are not paying more than you need to.

We work through your income from all sources — self-employment, employment, dividends, rental property, savings, pensions and capital gains — and apply the allowances and reliefs that actually apply to your circumstances. That includes trading allowances, capital allowances, pension contributions, Gift Aid, marriage allowance and the reliefs that are commonly missed.

Before anything is submitted you see a summary showing your total income, the tax due, the payment dates and how each figure was arrived at. Once you approve it, we file with HMRC and confirm receipt.

FAQs

Self Assessment — common questions

What is the Self Assessment deadline?

The online filing deadline is 31 January following the end of the tax year, and any balancing payment is due on the same date. Payments on account, where they apply, fall due on 31 January and 31 July.

I have missed a deadline — can you help?

Yes. We can bring late returns up to date, calculate what is owed and deal with HMRC over penalties and interest. Acting quickly usually reduces the total cost.

How is your fee worked out?

Fixed fee, agreed before we start. Pricing depends on the size and complexity of your business, so get in touch for a free, no-obligation quote.

Can you help if we're switching from another accountant?

Yes. We handle professional clearance with your previous accountant and update the agent authorisations with HMRC and Companies House, so you don't have to manage the handover.
