Amazon Flex Mileage Tracker - Claim Every Delivery Mile
Amazon Flex drivers in the UK cover serious mileage. A four-hour block in a suburban area can mean 40 to 80 miles of delivery routes. MileClear tracks every mile automatically, groups them into blocks that match how Flex actually works, and calculates your HMRC deduction in real time.

Why Mileage Tracking Matters for Amazon Flex Drivers
Amazon Flex drivers are classified as self-employed in the UK. That means you file a self-assessment tax return each year, and you are responsible for recording your own business expenses. Mileage is almost always the single largest deductible expense for Flex drivers.
HMRC's Approved Mileage Allowance Payment (AMAP) rate lets you claim 45p per mile for the first 10,000 business miles in a tax year, and 25p per mile after that. For a driver running two or three blocks per day, five days a week, that mileage can reach 25,000 to 35,000 miles per year - giving a tax deduction worth over £9,000 in some cases.
The problem is that HMRC requires a contemporaneous mileage log. You cannot estimate at the end of the year. You need a dated record of each journey with its purpose, start point, end point, and distance. Most Flex drivers do not keep one - and the ones who do often find that a rough spreadsheet is challenged by an accountant or rejected by HMRC.
MileClear records everything automatically using GPS. Every time you drive, MileClear is building the mileage log you need for self-assessment.
Block-Based Shifts - How MileClear Mirrors How Flex Works
Amazon Flex operates in blocks - typically two, three, or four hours. You accept a block, drive to the depot at the block start time, collect your packages, and begin deliveries. Some drivers do one block per day; others do multiple consecutive blocks or shift between stations in the same session.
MileClear's shift mode mirrors this pattern perfectly. Start a shift when you leave the depot with your first load. Every delivery trip within that shift is tracked and grouped under that single block session. When you return to the depot or complete your last drop, end the shift. You get a scorecard with the total miles for that block and - if you have entered your block earnings - your earnings per mile for that session.
This makes it easy to compare block types - Prime Now blocks versus standard delivery, grocery blocks versus parcels, city-centre dense routes versus suburban long-distance runs. Over time, the data shows you which blocks are actually worth your time once fuel is factored in.
What Amazon Flex Drivers Can and Cannot Claim
Business miles you CAN claim
- Depot to each delivery address
- Between delivery stops on your route
- Return trip from last delivery back to depot (if applicable to your block type)
- Positioning miles - driving to a different station or zone at Amazon's direction
- Any detour required due to access issues at a delivery address
Miles you CANNOT claim
- Home to depot at the start of your block - this is ordinary commuting in HMRC's view
- Depot to home after your final block of the day
- Personal errands between blocks
- Any non-Flex driving done in the same vehicle on the same day
The commute rule is important and frequently misunderstood. HMRC considers travel from a permanent place of work (including a depot you regularly report to) to be ordinary commuting, not a business journey. For most Amazon Flex drivers who consistently use the same station, the home-to-depot leg is not claimable. MileClear lets you mark that segment as personal so your records accurately reflect what is and is not a business mile.
How MileClear Fits Into Your Amazon Flex Routine
Automatic Detection at the Depot
Set your Amazon depot as a saved location in MileClear. When you leave the depot, MileClear can detect that you are starting a delivery run and prompt you to begin tracking. No need to unlock your phone before heading out.
Amazon Flex Platform Tag
Tag every shift and trip with Amazon Flex so your records are separated from personal driving. If you also do other delivery work, each platform stays in its own category.
Multi-Stop Route Tracking
Each delivery address is a stop within your shift. MileClear records the full route including inter-stop distances. At the end of the block, you have a complete mileage record for the entire route.
Return-to-Depot Miles
If your block includes returning to the depot after the last delivery, that return trip is also tracked as a business mile. MileClear does not cut off your record at the last drop.
Earnings Per Mile by Block Type
Enter your block earnings when you end the shift. MileClear calculates your effective earnings per mile and per hour for each block, so you can compare which block types are most profitable for the fuel you use.
HMRC-Ready Exports
Pro users get a PDF mileage log and self-assessment summary. Every trip is dated, timestamped, and distance-verified. Share it with your accountant or attach it directly to your HMRC online return.
Typical Savings for a UK Amazon Flex Driver
Amazon Flex drivers typically cover high mileage compared to other gig economy work. Delivery routes in suburban areas can involve 40 to 70 stops spread across 50 to 80 miles per block. Full-time Flex drivers running two blocks per day, six days a week, can accumulate 30,000 to 40,000 delivery miles per year.
Example: 25,000 Business Miles Per Year
At 40% tax (higher rate), that same 25,000 miles produces a saving of £3,300 per year from mileage alone. Even a part-time Flex driver doing 12,000 business miles per year would have a deduction of £4,900 - worth £980 in tax at the basic rate.
The question is not whether the deduction is worth claiming. It clearly is. The question is whether you have the records to claim it. MileClear provides those records automatically, every time you drive.
Fuel Costs and Amazon Flex Profitability
Fuel is the most significant running cost for Amazon Flex drivers, and it eats directly into your block earnings. A driver covering 60 miles in a block at 35 mpg uses approximately 1.7 gallons - around 7.7 litres. At current UK petrol prices of around 140p per litre, that is roughly £10.80 in fuel per block. On a four-hour block paying £50 to £60, fuel alone is 18 to 22% of gross earnings.
MileClear shows live fuel prices from over 8,300 UK stations using the government-mandated price reporting database. You can see which stations near you have the cheapest fuel before you start a block. Saving 5p per litre on a regular fill-up adds up to real money across a working week.
The fuel log feature also lets you log every fill-up with the cost, litres, and odometer reading. Over time, MileClear calculates your actual cost per mile from real data - not estimates - so you know exactly what your vehicle costs to run.
Amazon Flex Alongside Other Delivery Work
Many Amazon Flex drivers supplement their income with other delivery work - DPD, Yodel, Evri, or even Uber during quiet Amazon periods. From a tax perspective, all of this mileage is business miles and can be claimed under the same HMRC AMAP rules. But you need to be able to show which miles were for which employer, especially if HMRC queries your return.
MileClear tags every trip with the platform. Amazon Flex blocks are tagged separately from DPD days or Uber shifts. The business insights comparison then shows you which platforms deliver the best earnings per mile and per hour from your own real data - not industry averages.
If you drive for Uber or Deliveroo alongside Flex, see the dedicated guides: Uber mileage tracker and Deliveroo mileage tracker.
Frequently Asked Questions
Does Amazon Flex track mileage automatically?
No. The Amazon Flex app shows the route to each delivery, your block earnings, and package counts, but it does not record your driving distance for tax purposes. To claim HMRC mileage relief on Self Assessment you need a separate tracker that keeps a contemporaneous log of every block. MileClear records each block automatically using GPS - depot to last drop, plus the return trip - and produces an HMRC-ready mileage log.
Can Amazon Flex drivers claim mileage on their UK tax return?
Yes. Amazon Flex drivers are self-employed and can claim 45p per mile for the first 10,000 business miles and 25p per mile after that. Business miles include the full delivery route from depot to each drop, including inter-stop miles and any required return to depot.
Does driving to the Amazon depot count as a business mile?
No. The journey from home to the depot at the start of your block is ordinary commuting in HMRC's view and is not claimable. Miles from the depot onwards - to each delivery and back - are business miles.
How much can an Amazon Flex driver save on tax with mileage tracking?
A Flex driver covering 25,000 business miles per year has a deduction of £8,250. At a 20% tax rate that is a £1,650 saving directly from mileage allowance. At 40%, it is £3,300.
Does Amazon report Flex earnings to HMRC?
Yes. Amazon is required to report Flex driver payments under UK tax rules. Accurate expense records including a contemporaneous mileage log are essential to ensure you are only taxed on net profit, not gross earnings.
What format should a mileage log be in for Amazon Flex?
HMRC requires a record of each journey's date, start and end point, purpose, and distance. MileClear's Pro export produces a PDF mileage log in an accepted format, suitable for attaching to your self-assessment return or sharing with an accountant.
