Self Assessment tax return

Self Assessment tax returns done for you

Your personal tax return, prepared and filed for you. No January panic, and no guessing what you owe.

In short

Your personal tax return, done early.

Most people see their accountant in January, in a rush, with a year of paperwork they have not looked at. We would rather see you in June. The return is the same either way, but done early there is time to check whether you are paying too much up front and whether anything has been missed.

What is included

The tax return itself
We prepare it from your records and file it online. That covers self-employment, rent, partnerships, employment, money from abroad and anything you have sold.
Rent from property
We work out the profit on each property, apply the mortgage interest rules correctly, and split repairs (which you can claim) from improvements (which you cannot).
Selling a property or shares
We work out the tax and claim any relief you are due. If you sell a UK property, there is a separate report due within 60 days and we handle that too.
Payments on account
HMRC often asks you to pay next year’s tax in advance. If your income has dropped we apply to reduce it, so you are not lending HMRC money for a year.

Who this is for

  • Company directors who take dividends
  • Sole traders and builders paid under CIS
  • Landlords with one property or fifty
  • Anyone who has had a letter from HMRC and is not sure why

When it is due

Your return and any tax owed are due by 31 January after the tax year ends. Payments on account are due on 31 January and 31 July.

We confirm your dates in writing and keep track of them for you from then on.

What a Self Assessment accountant does for you

Self Assessment is how HMRC collects tax on income that has not already been taxed at source. A Self Assessment accountant gathers your figures, works out what you owe, claims what you are entitled to and files the return online. Done properly, it is also a yearly check that you are not paying more than you should.

We look after tax returns for people in Liverpool and across the UK. Each return is prepared by the same small team, reviewed by an ICAEW Chartered Accountant, and only filed once you have seen and approved it.

  • Self-employed profits, including builders paid under CIS
  • Rental income, with the mortgage interest rules applied correctly
  • Dividends and salary for company directors
  • Gains on selling shares or property, including the 60-day report for UK homes
  • Checking and, where it is justified, reducing your payments on account

Do you need to file a tax return?

You usually need one if you have self-employed income over £1,000 (the trading allowance), untaxed income such as rent, some company director income, or a letter from HMRC asking you to file. Our guide on whether you need to do a Self Assessment goes through each case.

If you need a return for the first time, you must register by 5 October after the end of that tax year. We can register you as part of the job.

England, Wales and Northern Ireland. Scotland has its own bands for earned income.
Taxable income band (2026/27)Income tax rate
Up to £12,570 (Personal Allowance)0%
£12,571 to £50,27020% basic rate
£50,271 to £125,14040% higher rate
Over £125,14045% additional rate

The Personal Allowance shrinks by £1 for every £2 of income over £100,000, and is gone at £125,140. If you are self-employed you also pay Class 4 National Insurance: 6% on profits between £12,570 and £50,270, and 2% above that.

Self Assessment deadlines and payments on account

Key dates for the 2025/26 return
DeadlineWhat is due

Payments on account are advance payments towards next year’s bill. Each is usually half of last year’s tax. You do not have to make them if last year’s bill was under £1,000, or if more than 80% of your tax was already paid at source, for example through PAYE. Our Self Assessment deadline guide covers this in more detail.

How much does a tax return accountant cost?

Our fixed monthly fees start from £99 for self-employed people and landlords. The exact figure depends on how many income sources you have and the state of your records. You get it in writing after a free chat, and it is fixed for 12 months unless things change. Full details are on our fees page.

What to send us

  • Your Unique Taxpayer Reference (UTR) and National Insurance number
  • Income and expense records, or bank statements if that is all you have
  • CIS statements from each contractor, if you work in construction
  • Rent statements and mortgage interest figures for any property
  • P60, P11D or dividend vouchers if you are employed or a director
  • Details of anything you sold, such as shares or a property

Common questions

How early can my tax return be filed?

From 6 April, once the tax year has ended and you have your figures. Filing early does not mean paying early. The tax is still due on 31 January.

I have never filed before. Can you register me?

Yes. We register you with HMRC so you get your Unique Taxpayer Reference, then prepare the return. The registration deadline is 5 October after the tax year you first need a return for.

Can you help if I am in Scotland?

Yes. We work online with clients anywhere in the UK. Scotland has different income tax bands for earnings, and we apply them on your return.

Will you deal with HMRC if they write to me?

Yes. Once we are your agent, HMRC can talk to us directly. Send us any letter you receive and we will tell you what it means.

How we run it

A routine, not a panic

We agree at the start what we need from you and when, and what you get back and when. After that it just happens, without anyone chasing anyone.

You get a written list of every date that applies to you, a reminder before each one, and the filing done early. If something changes in your business we change the plan, instead of finding out about it at the year end.

  • Tax returns for company directors, sole traders and partners
  • Money you make from renting out property
  • Tax on selling a property or shares
  • We check you are not paying HMRC more than you need to
