Built for UK Drivers, by People Who Get It

Why We Built This

The UK has over 300,000 licensed taxi and private hire drivers, plus hundreds of thousands more delivery drivers working for platforms like Amazon Flex, Deliveroo, and Uber Eats. The vast majority are self-employed — and many overpay tax simply because they don't know what expenses they're entitled to claim, or they underestimate the power of HMRC's Approved Mileage Allowance.

We built Driver-Tax.co.uk to fix that. Our calculator applies the exact HMRC 2025/26 rules — the 45p/25p mileage tiers, the £12,570 personal allowance, the Class 4 NI thresholds — and shows you your real estimated take-home pay in seconds, for free.

Our Commitment to Privacy

We made a deliberate architectural decision: your financial data never leaves your device. Every number you type into the calculator is processed entirely in your browser's JavaScript engine. Nothing is sent to a server. Nothing is logged. Nothing is stored. When you close the tab, it's gone.

We earn revenue through non-intrusive advertisements (Google AdSense) so that we can keep the tool free. Ads are the only way we monetise — your data is not, and never will be, a product.

What the Calculator Covers

• Conversion of weekly or monthly earnings to annual gross income
• HMRC Approved Mileage Allowance Payments (AMAP) — 45p/mile (first 10,000), 25p/mile (above)
• Income Tax at the basic rate (20%) and higher rate (40%)
• Class 4 National Insurance at 6% and 2%
• Net take-home pay (monthly and annual)
• A step-by-step breakdown of every calculation stage

Our Tax Guides section provides free, in-depth articles on UK driver tax topics — from filing your Self Assessment return to understanding which expenses you can legitimately claim.

What the Calculator Does Not Replace

We are transparent about the limitations of an online estimator. Our tool does not account for student loan repayments, pension contributions, Gift Aid donations, multiple income sources, the personal allowance taper above £100,000, or capital allowances on vehicles. It is a planning tool, not a substitute for professional advice.

For your Self Assessment tax return, we strongly recommend using a registered accountant or HMRC's free online filing service at gov.uk/log-in-file-self-assessment-tax-return.
