Are Amazon Flex Drivers Employed or Self-Employed in the UK?
Amazon Flex drivers in the UK are classified as self-employed independent contractors. Amazon pays gross earnings without deducting tax, National Insurance, or making pension contributions. You must report all Flex income on a Self Assessment tax return and pay your own tax and NI.
This classification applies regardless of how many hours you work or how many blocks you complete each week. If you drive for multiple platforms simultaneously — such as Amazon Flex and Uber Eats — all income is combined and reported together on a single Self Assessment return. See our Amazon Flex tax calculator to estimate your bill instantly.
- No PAYE deduction: Amazon Flex does not withhold income tax or NI at source
- No employer pension: You are not automatically enrolled in a workplace pension
- Trading allowance: If total Flex income is under £1,000, no tax is due and no return needed
- Multiple income sources: Flex income is added to any other self-employment income for tax
"Workers who are self-employed are responsible for paying their own Income Tax and National Insurance. They must register with HMRC and submit a Self Assessment tax return each year."

How Do Amazon Flex Drivers Claim Mileage in the UK?

| Annual Delivery Miles | AMAP Rate | Total Deduction | Tax Saving (20% band) |
|---|---|---|---|
| 8,000 miles | 45p/mile | £3,600 | £720 + NI saving |

| 20,000 miles | 45p first 10k, 25p after | £7,000 | £1,400 + NI saving |
| Most Flex drivers | Standard AMAP | £3,600–£7,000 | Largest single deduction |
- Log every delivery block: Record date, start postcode, end postcode, and total miles for each shift
- Include all business miles: Driving from home to first delivery, between drops, and returning counts
- Apps to track mileage: MileIQ, Driversnote, or manual logbook — all accepted by HMRC
- Cannot combine AMAP with actual costs: Choose one method per vehicle per tax year
What Expenses Can Amazon Flex Drivers Claim in the UK?
Beyond mileage, Amazon Flex drivers can deduct phone costs, vehicle insurance (business proportion), parking and tolls, delivery equipment, and accountant fees. Claiming all available expenses typically reduces net profit by £1,500–£3,000 beyond mileage alone.
- Vehicle mileage: 45p/mile first 10,000 miles, 25p/mile after — the largest deduction
- Mobile phone: Business-use proportion of your bill (70–90% for most full-time drivers)
- Vehicle insurance: Business-use proportion if you added courier cover to your policy
- Parking and tolls: Any parking fees or toll charges incurred during delivery blocks
- Delivery bags and equipment: Thermal bags, phone mounts, chargers used for deliveries
- Accountant fees: Cost of professional tax advice and Self Assessment filing
- Data plan: Mobile data used for the Amazon Flex app during deliveries
For the full list of HMRC-approved expenses see our self-employed expenses guide. You cannot claim clothing, personal food, or commuting from home to a regular workplace.
Do Amazon Flex Drivers Need to Register for Self Assessment?
Yes — register by 5 October following the end of the tax year in which your Flex income exceeds £1,000. For the 2025/26 tax year (ending 5 April 2026), the registration deadline is 5 October 2026. File your return and pay by 31 January 2027.

Do Amazon Flex Drivers Pay Tax Quarterly in the UK?
HMRC does not require quarterly tax payments in the UK — tax is paid annually by 31 January. However, if your tax bill exceeds £1,000, HMRC requires payments on account — two advance payments of 50% of last year's bill, due 31 January and 31 July.
Unlike the US quarterly system, UK Self Assessment tax is settled once per year. However, setting aside 25–30% of each payment from Amazon Flex into a separate savings account ensures you have funds available when your tax bill is due. See our HMRC Self Assessment guide for full payment deadlines and how payments on account work.
- 31 January 2027: Pay tax for 2025/26 + first payment on account for 2026/27
- 31 July 2027: Second payment on account for 2026/27
- Set aside 25–30%: Of every Amazon Flex payment to cover your annual bill
- Late payment penalty: 5% of unpaid tax after 30 days, then escalating surcharges
