Need to file your self assessment tax return? ABM Chartered Accountants prepares, calculates, and submits your return to HMRC with every allowable expense claimed and every deadline met. No stress, no penalties, no surprises.
Get Your Self Assessment Done Properly
If you earn income outside of PAYE, whether as a sole trader, landlord, company director, or freelancer, HMRC requires you to file a self assessment tax return each year. Getting it wrong means penalties, overpaid tax, or unwanted attention from HMRC. ABM Chartered Accountants makes sure it is done right.
Our ICAEW and ACCA qualified accountants handle every aspect of your self assessment, from gathering your records and calculating your liability to claiming every relief you are entitled to and filing your return online with HMRC. We take the pressure off completely so you can get on with life.

Frequently Asked Questions
Here are answers to the self assessment questions we hear most often. Get in touch for personalised advice.
Who needs to file a self assessment tax return?
You need to file if you are self-employed, a landlord, a company director, a high earner, or if you have income that is not taxed at source through PAYE. HMRC will usually notify you.
What is the deadline for filing a self assessment return?
The online filing deadline is 31 January following the end of the tax year. For example, the return for the 2024/25 tax year must be filed online by 31 January 2026. Late filing attracts penalties.
What happens if I file my return late?
HMRC charges a 100 pound penalty immediately if your return is late. Further penalties apply after three, six, and twelve months. Interest is also charged on any tax paid after the deadline.
Can you help me claim all my allowable expenses?
Yes. ABM Chartered Accountants identifies every expense you are entitled to claim, from travel and equipment to professional subscriptions and home office costs. Claiming correctly reduces your tax bill significantly.
What are payments on account?
Payments on account are advance payments towards next year’s tax bill, due on 31 January and 31 July. They are based on the previous year’s liability. We help you budget and plan for these.
How much do your self assessment services cost?
Fees depend on the complexity of your tax affairs and the number of income sources involved. We offer fixed-fee pricing with no hidden charges. Contact us for a personalised quote.
