What are simplified expenses for the self-employed? Simplified expenses are flat rates you can use instead of actual costs for three things: vehicles (55p a mile for the first 10,000 business miles in 2026-27), working from home, and living at your business premises. No. GOV.UK says they are optional, and HMRC's manual says you can use them whether or not you also use the cash basis. You can work out actual costs instead. No. HMRC's Business Income Manual says there is no business income limit. They are open to sole traders and to partnerships with no company as a partner. Yes.
