Self Assessment

Straightforward, fixed-fee self-assessment returns for sole traders, landlords, directors and PAYE clients with side income.

Fixed fees

From £199 all-in — no hourly billing.

Around a third of our new personal-tax clients arrive after a bad experience with an online-only firm: hidden add-ons, delayed responses, or a bill that inflated once the return got started. We do it differently.

Every self-assessment engagement starts with a 30-minute call — usually free — during which we walk through your income sources and quote a fixed, all-in fee. No add-ons for extra schedules. No hourly rate. No surprise invoice in January.

  • Sole trader (turnover under £85k) — from £199
  • Rental income (up to 2 properties) — from £245
  • Rental portfolio (3+ properties) — from £395
  • Capital gains & disposal reporting — from £150 additional
  • Non-dom or split-year residence — POA
