Self Assessment Tax Return Accountants for the Self-Employed
Stress-free tax returns for sole traders, drivers, landlords, contractors and company directors.
A tax return should not keep you up at night. At WPC Accountants, we take the whole job off your hands, from working out what you owe to claiming every allowable expense and filing on time. Whether you drive for a living, let out property, run your own trade or earn income on the side, we make sure your return is accurate, your bill is as low as the law allows and you never miss a deadline.

You usually need to send a return if any of the situations below apply. If you are not sure, we will check for you.

Tax returns for delivery and private-hire drivers
If you drive for Uber, Bolt, Deliveroo, Just Eat, Amazon Flex or as a taxi or private-hire driver, you are self-employed in the eyes of HMRC. That means you need to register and file a Self Assessment on the money you earn. It sounds daunting, but this is one of our most common jobs and we make it simple.
We help drivers:
- Register with HMRC and get your UTR set up (see our self-employment registration service)
- Work out your profit from your earnings summaries and statements
- Claim mileage and running costs correctly (45p/mile for the first 10,000 miles, then 25p), so you do not overpay
- Claim other allowable costs such as your phone, insurance and platform fees
- File on time and tell you exactly what to pay and when
