UK · Self Assessment
Prepare your UK self assessment with less stress. FinnAccountings organises your income and expenses, applies HMRC rules, and produces an SA100 draft ready for your review and qualified sign-off.
HMRC self-assessment covers trading profits, employment, dividends, and property income on SA100 and supplementary pages. Payments on account split liability across January and July if prior-year tax exceeded £1,000.
FinnAccountings estimates income tax and Class 4 National Insurance using current UK bands, and tracks allowable expenses against Making Tax Digital record-keeping rules.
Making Tax Digital for Income Tax Self Assessment will require quarterly digital updates for qualifying traders. Starting with digital books now reduces friction when thresholds apply.
