Keep a mileage log in 20 seconds a trip
You drive for work but never record it, then guess at tax time. Set up a phone form that logs each trip into a spreadsheet and adds up the miles for you.
The prompt · ChatGPT
Help me set up a quick mileage log. My trips: [e.g. jobs, supplier runs, site visits] Vehicle: [car, van, motorbike, bike] How I'd like to log: [phone form at the end of each trip] First ask me up to 3 short questions. Wait for my answers. Then: 1. The form questions: date, from, to, purpose, miles, with the type of answer for each. 2. A spreadsheet layout with monthly and tax-year totals, and the formulas. 3. Look up the GOV.UK pages on vehicle expenses and simplified expenses for the self-employed. Name them, and tell me which choice I need to ask my accountant about. 4. A weekly check routine. Not tax advice. Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English. For GOV.UK vehicle and simplified expenses pages, use web search and name the page you used. If it doesn't search on its own, open View all tools and choose Search. Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.
A short example
Fill the blanks, then paste. e.g. jobs, supplier runs, site visits: a short note you already have. car, van, motorbike, bike: a short note you already have. Leave the rest of the prompt as written.
This does not give tax advice. The books stay in the accounting system.
