Key takeaways
- Amazon Flex drivers are self-employed and responsible for their own tax — nothing is deducted at source.
- You must register for Self Assessment once your Flex income (before expenses) passes £1,000 in a tax year.
- Block payments and any tips or bonuses both count as taxable income.
- Mileage between blocks, phone data, and safety equipment are all allowable expenses.
- If Flex is a side income alongside employment, it's still taxed and reported separately through Self Assessment.
Amazon Flex pays you per delivery block, with no tax taken off before it reaches your bank account. That means the responsibility for registering with HMRC, tracking your income, and paying the right tax sits entirely with you as a self-employed driver — this guide walks through exactly what that involves.
Quick answer: how is Amazon Flex income taxed?
As an Amazon Flex driver you're self-employed, not an employee of Amazon. You're paid gross for each block you complete, and you're responsible for registering with HMRC, filing a Self Assessment return, and paying your own Income Tax and National Insurance on your profit after allowable expenses.
How Amazon Flex pay works
You're paid per delivery block you accept and complete, sometimes with additional tips or surge/boost pay during busy periods. None of this has tax deducted before it reaches you — the amount that lands in your bank account is your gross income, not your take-home pay.
Registering for Self Assessment
Once your self-employed income (including Flex, before any expenses) passes £1,000 in a tax year, you need to register with HMRC and file an annual Self Assessment return. It's worth registering as soon as you start driving regularly rather than waiting until you're close to the threshold.
What counts as income
All block payments, tips, and any bonus or incentive pay from Amazon Flex count as business income. If you also drive for other platforms alongside Flex, that income is combined into the same Self Assessment return, not filed separately.
Expenses specific to Flex driving
- Mileage or actual vehicle costs for driving to warehouses and between delivery stops
- Phone data and app usage for accepting and navigating blocks
- Parking at or near delivery locations
- Safety equipment, delivery bags, or trolleys if you use them
- A share of vehicle insurance, or dedicated Goods in Transit cover if applicable
Record keeping for Flex drivers
Amazon Flex's app shows a history of completed blocks and payments — keep screenshots or exports of this alongside your bank statements, since it's the clearest evidence of your income for the year. Keep a simple mileage log for journeys to and from warehouses and between drop-offs.
National Insurance and Payments on Account
As a self-employed driver you pay Class 4 National Insurance on your profits, in addition to Income Tax. If your tax bill is over £1,000, HMRC will usually ask for Payments on Account — advance instalments towards next year's bill — so it's worth setting money aside rather than being caught out.
Flex as a side income
If you drive for Flex alongside employed work, your Flex profit is still reported through Self Assessment and taxed on top of your employment income, potentially at a higher marginal rate. Registering and reporting it properly avoids a much larger, unexpected bill later.

Frequently asked questions
Does Amazon take tax off my Flex payments?
No. You're paid gross for every block, and you're responsible for registering with HMRC and paying your own Income Tax and National Insurance.
Do I need to register if Flex is only a side income?
Yes, once your self-employed income from Flex (and any other self-employed work) passes £1,000 in a tax year, before expenses.
Can I claim mileage to the warehouse before my first delivery?
Generally yes, if it's part of your delivery round rather than a fixed daily commute to one location — we can help you work through your specific pattern.
What if I drive for Flex and another platform?
All your self-employed delivery income is combined into a single Self Assessment return, with expenses claimed across the whole business, not per platform.
