Self Assessment Tax Returns

We take care of your self-assessment tax return from start to finish — accurately, on time, and at a fixed fee. No stress, no jargon, no nasty surprises.

Do you need to do a self-assessment return?

If you're self-employed, a sole trader, a freelancer, a landlord, or you earn more than £100,000 a year, you almost certainly need to complete a self-assessment tax return each year. It's how HMRC collects tax on income that isn't taxed automatically through PAYE.

Many people find self-assessment confusing, time-consuming and stressful — especially the first time. That's where we come in. We handle the whole thing on your behalf, so you can get on with running your business.

What we do for you

When you come to us for self-assessment, here's what we take care of:

  • Review all of your income sources for the tax year
  • Identify all allowable expenses you can claim
  • Prepare your SA100 tax return accurately
  • Calculate your exact tax liability
  • Submit your return to HMRC digitally, well before the deadline
  • Explain your tax bill in plain English so you know what you owe and when
  • Set up a payment plan with HMRC if needed

We also flag payments on account — the advance payments HMRC often requires — so you're never caught off guard.

What expenses can you claim?

Depending on what you do for a living, you may be able to claim expenses for things like:

  • Home office costs if you work from home
  • Business travel and mileage
  • Professional subscriptions and training
  • Equipment, tools and software
  • Marketing and advertising costs
  • Accountancy and professional fees
  • Use of your own vehicle

Getting your expenses right can make a significant difference to your tax bill. We make sure you claim everything you're entitled to — nothing more, nothing less.

Missed the deadline? We can still help.

If you've missed the 31st January filing deadline, don't panic. The penalties for late filing start at £100, and they increase over time — but the sooner you act, the better. Get in touch and we'll help you get things in order as quickly as possible.

Frequently asked questions

How much does a self-assessment return cost?
Our self-assessment service starts from a fixed fee agreed upfront before we start any work. There are no hidden extras. Contact us for a quote tailored to your situation.
When is the self-assessment deadline?
The deadline for online filing is 31st January each year, for the previous tax year (which ends 5th April). So the return for the 2024/25 tax year is due by 31st January 2026.
What do I need to give you?
We'll give you a clear checklist of what we need — things like your income totals, expense records, any P60s or bank interest statements. You don't need to have it all perfectly organised. We're used to working with what clients have.
Can I switch to you from another accountant?
Absolutely. We handle the whole switch for you, including contacting your previous accountant for the files we need. It's a very smooth process and most clients are surprised by how easy it is.

"I'd been avoiding doing my tax return for two years and was terrified. Tom sorted it all out in a week, claimed expenses I hadn't even thought of, and saved me over £800. Genuinely brilliant."
