Why Most Sole Traders & Uber Drivers Overpay Tax (and How to Keep More of Your Money)

Self-employed workers are some of the most overtaxed people in the UK — not because they earn more, but because their bookkeeping is often incorrect.

Every year thousands of drivers and sole traders lose money to missed expenses, mileage mistakes, VAT errors, and incorrect HMRC reporting.

Here is where the money is leaking.

Mistake 1 – Not Tracking Mileage

Mileage alone can save £2,000 – £6,000 per year

Missing this = lost money.

Fix:

Set up mileage tracking inside your accounting system.

Mistake 2 – Missing Allowable Expenses

Drivers often miss:

• Phone & data
• Car repairs
• Fuel
• Insurance
• Equipment
• Home office use

Fix:

Set proper expense categories in Xero / QuickBooks.

Mistake 3 – Mixing Personal & Business Money

This causes:

• Lost expenses
• Wrong profits
• HMRC risk

Fix:

Separate business accounts and automated bank feeds.

Mistake 4 – Late Bookkeeping

Late records = surprise tax bills.

Fix:

Monthly bookkeeping & early tax forecasting.

Mistake 5 – No Professional Review

Drivers without professional oversight consistently overpay tax.
