The details that decide your bill — done properly.
We track the 20% contractors take at source, so it lands as the refund you're owed the moment your return is filed.
Win the job with a quote, turn it into an invoice in a tap, mark it paid — and it's already in your books.
Actual running costs or mileage — whichever's bigger — with capital allowances on the vehicle worked out for you.
We file the right way for how you trade, and your accountant can log in to review and certify before it goes to HMRC.
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.
Less than a tank of fuel a month — and it pays for itself in the costs it helps you claim.

Because ours is right. Self-employed drivers pay Class 4 National Insurance on top of Income Tax, and often payments on account too. Free calculators usually leave those out, so the bill looks smaller than it really is — until HMRC's does. We'd rather you saw the true number early.
Whichever gives you the bigger deduction — and we compute both for you. For high-mileage vans, real fuel, insurance, servicing and repair costs often beat the flat mileage rate. You pick one method per vehicle and we keep you to it, as HMRC requires.
It phases in by income: over £50,000 from April 2026, over £30,000 from April 2027, and over £20,000 from April 2028. Even if you're not in yet, keeping clean digital records now means you claim every cost and switch over painlessly.
Your call — same books either way. If you're confident, file straight to HMRC from the app. If you'd rather have it checked, your accountant logs into the same portal, reviews the numbers we've prepared, certifies them, and it's filed. You never export to another tool.
Log what your contractor paid you and the CIS they deducted (or let us work it out from your labour and status). We total it up, set it against your real tax bill once your costs are in, and show the refund you're owed — ready to file.
Your records are yours. Everything is stored securely, nothing is sold, and you can export or delete your data whenever you like.
Set up in minutes. Your first 90 days are free, and you approve everything before it counts.
