Self Assessment is the system HMRC uses to collect Income Tax from people whose tax isn't automatically deducted at source. If you're a sole trader, freelancer, landlord, or company director with dividends — you probably need to file one.
Each year, you report your income and expenses to HMRC. They calculate what you owe, and you pay by the deadline. Sounds simple, but the details matter.
From April 2026, self-employed individuals and landlords earning over £50,000 must keep digital records and file quarterly updates with HMRC. This is a major change to how Self Assessment works.

Self Assessment is for individuals — not companies. If you have personal income that isn't taxed at source, this is the service you need.
We don't wait until January to look at your numbers. We review your income and expenses throughout the year so you can make decisions that reduce your tax bill and not scramble at the last minute like everyone else.
We prepare your tax return and file it with HMRC. We check every income source, apply all allowable expenses, and make sure you're claiming everything you're entitled to. No nasty surprises.
If your tax bill is over £1,000, HMRC will ask for payments on account, advance payments towards next year's bill. We help you understand what's coming and plan your cashflow so you're not caught off guard.
Let's have a conversation — we'll get to know you, your income sources, your challenges, and where you want to go.
We'll propose a plan, provide a clear quote, and outline the next steps — no surprises, just a smooth setup.
If you decide to come onboard, we'll gather your data, prepare your return, and handle HMRC. If you're switching accountants, we'll contact your previous accountant and take care of the transfer.
At GenTax, we turn tax return season into a streamlined, data-driven process tailored to your financial picture.
If meeting in person is a hassle? We work with you over video call and give you secure, GDPR-compliant ways to upload your documents when it suits you—saving you time and making the whole process fit around your schedule.
