If your situation is more complex than a calculator can handle — director and sole trader income mixed, multiple properties, pension contributions, tapering at £100k — book a free 20-minute call and we'll work through it together.
Book a free 20-min callThe calculators use current 2026/27 UK tax rates verified against HMRC publications: personal allowance £12,570, basic rate 20%, higher rate 40%, additional rate 45%, new dividend rates of 10.75%/35.75%/39.35% effective 6 April 2026. They produce indicative figures for typical scenarios. Edge cases (Scottish taxpayers, pension contributions, Marriage Allowance transfers, salary sacrifice, student loans, child benefit charge) require professional advice.
No. All calculations run entirely in your browser. Nothing is sent to our server, nothing is stored, nothing is shared. You can use these calculators completely anonymously. We've deliberately avoided gating them with an email signup.
Not currently. The income tax bands used apply to England, Wales and Northern Ireland. Scottish taxpayers have different bands and rates (starter, basic, intermediate, higher, top, advanced). If you're a Scottish taxpayer, the figures will be approximate only. Get in touch for exact Scottish calculations.
Whenever rates change. The current versions reflect tax year 2026/27 (6 April 2026 — 5 April 2027) including the new dividend rates that took effect on 6 April 2026. We'll update again at the next Budget or April 2027 rate change, whichever comes first.
That's exactly when you need a real conversation, not a calculator. Pension contributions, Marriage Allowance, salary sacrifice, Scottish residence, mixed sole-trader and director income, dividend timing across tax years, capital gains, EIS/SEIS, R&D credits — these all interact in ways calculators can't capture. Book a free 20-min call and we'll work through your specific position.
