Your estimate includes Income Tax, Class 4 National Insurance and payments on account — the figures free calculators leave out. If wyse.tax ever miscalculates your tax from the records you approved, we'll fix it and work with you to put it right with HMRC.
- Every estimate includes National Insurance and payments on account — not just Income Tax.
- We show actual-cost vs simplified-mileage and claim the larger, so you never over-pay by under-claiming.
- You approve every figure before anything is prepared for HMRC — nothing is filed behind your back.
- If we get the maths wrong on records you approved, we'll correct it and help you amend with HMRC.
