Per-diem and meals
Free meals providedEach meal provided free of charge reduces the per-diem by the percentage shown. The base is the per-diem due for the day on which the meal was provided — for a part-day that is half or a third of the rate, so the deduction is proportionately smaller.
Documented costs
How you travelledTrain, plane, bus, taxi — no cap, at the amount on the document.
Enter the amounts from your invoices and receipts. These are not flat-rate allowances — a sole trader is not entitled to those, and accommodation is settled at the amount actually spent, without the cap that binds an employee. There has been no mileage allowance for sole traders since 2019, which is why spending on a passenger car goes into costs only in part.
This tool works out the per-diem and assembles the document — it does not replace an accountant's judgement. Whether a given trip is business travel depends on its connection with your business.
