Understanding your results
Gross Income: Your total earnings from Amazon Flex blocks before any expenses or taxes are deducted.
Total Expenses: The sum of your mileage allowance (or vehicle costs) and other allowable expenses. This amount is deducted from your gross income to find your taxable profit.
Taxable Profit: The amount you actually pay tax on. It's your Gross Income minus your Total Expenses.
Income Tax: Calculated using the 2025/2026 UK tax bands (20% basic rate, 40% higher rate, 45% additional rate) after your £12,570 Personal Allowance.
National Insurance: Calculated based on Class 4 NI rates for self-employed individuals (6% on profits between £12,570 and £50,270, and 2% above that).
Common Allowable Expenses
- Vehicle Costs: You can either claim a flat rate for mileage (45p/25p) OR actual costs (fuel, insurance, repairs, MOT, road tax). You cannot claim both.
- Mobile Phone: The business use percentage of your phone bill, essential for the Flex app.
- Delivery Gear: High-visibility clothing, trollies, or phone mounts.
- Insurance: Hire and reward insurance for parcel delivery.
