**TL;DR:** Step-by-step tutorial to issue an HMRC-friendly mileage receipt with the dedicated UK calculator.

- Gather: - Origin and destination (postcodes improve accuracy). - Journey date. - Business purpose (client visited, off-site training, etc.). - Vehicle make/model and registration plate. - Per-mile rate (45p / 25p AMAP, or your company's rate).
- The page renders in British English with miles and pounds, and the AMAP rates table is visible at the top.
- The calculator uses OpenStreetMap and returns real driving distance, not as the crow flies.
- Enter 45p for the first 10,000 business miles in the tax year, 25p above.
- Be specific: "Client visit Acme Ltd", "Off-site training, Manchester office".

## Before you start

Gather:

- Origin and destination (postcodes improve accuracy).
- Journey date.
- Business purpose (client visited, off-site training, etc.).
- Vehicle make/model and registration plate.
- Per-mile rate (45p / 25p AMAP, or your company's rate).

## Step 1: Open the UK calculator

Go to /mileage-calculator-uk.[^hmrc-amap] The page renders in British English with miles and pounds, and the AMAP rates table is visible at the top.

## Step 2: Enter origin and destination

The calculator uses OpenStreetMap and returns real driving distance, not as the crow flies. Toggle "return journey" to double the mileage automatically.

## Step 3: Apply the AMAP rate

Enter 45p for the first 10,000 business miles in the tax year, 25p above. The system multiplies miles × rate and shows the total in pounds. If you're unsure how many of the year's 10,000 miles you've already used, the dashboard tracks the running total automatically.

## Step 4: Add business purpose and vehicle

Be specific: "Client visit Acme Ltd", "Off-site training, Manchester office". Vague entries ("meeting") are the first thing HMRC challenges. Vehicle plate goes in the dedicated field.

## Step 5: Generate the PDF

The PDF includes date, origin, destination, route map, miles, rate, amount, business purpose, plate and a SHA-256 integrity hash. It satisfies HMRC's contemporaneous-log requirement and supports both employer reimbursement and a personal MAR claim.

## Step 6: Submit and archive

Submit through the company expense system (typically within the 30-day policy window). The company retains the receipt for 6 years. Quilometragem keeps a copy in your account for re-download at any time.

## Tips

- **Track passengers.** If a colleague was with you on a business journey, your employer can reimburse 5p/mile/passenger tax-free.
- **Mind the 24-month rule.** A "temporary workplace" stops being temporary if you expect to spend more than 24 months there. Trips to it then become commuting (not eligible).
- **Keep VAT fuel receipts.** Even though they're not part of the receipt itself, if your employer reclaims VAT on the fuel element, you'll need them.

## For finance

Export monthly receipts to CSV. Each row carries date, origin, destination, miles, rate, amount, business purpose, plate and integrity hash. Ready for payroll, the auditor and a P11D check at year-end.
