Amazon Flex tax guide in the United Kingdom

Amazon Flex drivers in the UK typically operate as self-employed contractors. Understanding how taxable profit is calculated and how Self Assessment works is essential for compliant reporting.

Are Amazon Flex drivers self-employed?

Amazon Flex drivers generally operate as self-employed contractors rather than employees.

This means drivers are responsible for managing their own tax reporting and National Insurance contributions.

Income is typically reported through the Self Assessment system.

The £1,000 trading allowance

The UK trading allowance allows up to £1,000 of gross trading income in a tax year without registering for Self Assessment.

If Amazon Flex income exceeds this threshold, drivers generally need to register as self-employed and report earnings.

How taxable profit is calculated

Taxable profit is calculated by subtracting allowable business expenses from gross income.

For many drivers, the most common allowable expense is mileage under HMRC’s approved mileage allowance rules.

  • Taxable profit = Gross block pay − allowable expenses.
  • HMRC mileage allowance is 45p per mile for the first 10,000 miles.
  • After 10,000 miles, the rate reduces to 25p per mile.

Mileage allowance vs real running cost

HMRC mileage allowance reduces taxable profit but does not represent your actual fuel or vehicle cost.

Real cash earnings may differ from taxable profit because mileage allowance is a tax mechanism rather than a direct expense reimbursement.

Understanding this distinction prevents confusion when reviewing earnings.

Self Assessment deadlines

The UK tax year runs from 6 April to 5 April the following year.

Online Self Assessment tax returns are typically due by 31 January following the end of the tax year.

Late filing or payment may result in penalties.

Payments on account

If your tax bill exceeds a certain threshold, HMRC may require payments on account towards the next tax year.

These are advance payments based on the previous year's tax liability.

Keeping accurate records

Drivers should maintain records of income, mileage and allowable expenses throughout the year.

Accurate record-keeping simplifies tax reporting and reduces the risk of errors.
