Self-Employed Delivery Driver Tax: The Basics

Join us to uncover essential tips and tricks for paying tax as a self-employed courier, ensuring a hassle-free tax filing process.

Knowing how to handle your own taxes is a big part of being self-employed in the UK. The process revolves around a system called Self Assessment, which is how HM Revenue & Customs (HMRC) collects Income Tax and National Insurance from people who don’t have it taken directly from their wages.

Registering and Understanding the System

You need to tell HMRC you’re self-employed and will be filing a tax return. The system assigns a unique number to each person, known as a Unique Taxpayer Reference (UTR). You will need to register by 5 October in the second tax year of your business. For instance, if you started your business in the tax year that ran from 6 April 2024 to 5 April 2025, you must register by 5 October 2025. It’s important to register on time to avoid a fine.

Your tax bill is based on your taxable profit, which is calculated by subtracting your allowable business expenses from your total business income. The amount of tax you pay on that profit depends on which tax band your income falls into. The Personal Allowance lets you earn a certain amount of income without paying any tax at all. For the 2024/25 tax year, the personal allowance is £12,570. Once you earn more than that, you will pay tax at the introductory rate, then the higher rate, and so on.

Making Tax Digital (MTD)

The way people submit their tax returns is changing. A new system called Making Tax Digital (MTD) for Income Tax is being introduced. From April 2026, sole traders with an income over £50,000 will be required to keep digital records and submit quarterly tax updates to HMRC through approved software. This means they will stop using the traditional yearly Self Assessment tax return. For those with an income between £30,000 and £50,000, the new rules will apply from April 2027.

Finding and Claiming Business Expenses

The money you spend on items that are wholly and exclusively for your business can be claimed as a business expense. This helps lower your taxable profit. You can claim for a wide variety of costs.

  • Office and Equipment Costs include stationery, computers, printers, software and phone bills.
  • Travel Costs cover business travel, like fuel, train fares, bus tickets, parking fees and accommodation if you stay overnight for work. You cannot claim for commuting.
  • Legal and Financial Costs include fees for accountants or solicitors, bank charges and interest on business loans.
  • Marketing Expenses cover things like website costs, advertising and promotional materials.
  • Business Premises Costs can include rent, heating, electricity and insurance for your office or warehouse. If you work from home, you can claim a portion of household bills.

Some costs are not allowable. For example, you cannot claim for personal items, fines for breaking the law, or the cost of preparing your tax return itself.

Filing Your Tax Return and Payments

The deadlines for filing your Self Assessment tax return are critical.

  • 31 January is the deadline for submitting your online tax return and paying any tax you owe for the previous tax year.
  • 31 October is the deadline for filing a paper tax return, which is earlier.

You may also have to make Payments on Account. These are advance payments towards your next tax bill, made in two instalments on 31 January and 31 July. Each payment is half of your previous year’s tax bill. This can often be a surprise for people in their first year of trading, as their first tax bill can be much larger due to a combination of the first year’s tax and the first Payment on Account.
