Every year, millions of people across the UK need to submit a Self Assessment tax return. According to HMRC, more than 11 million customers are expected to file a Self Assessment tax return each year. Yet many still miss deadlines, claim the wrong expenses, or pay more tax than they should simply because they are unsure of the rules.
If you are a sole trader, landlord, freelancer, contractor, or someone with income outside PAYE, tax can quickly become confusing. A missed deadline can lead to penalties, while small mistakes may result in unwanted questions from HMRC. This is where a personal tax accountant can make a real difference. They help you file your tax return correctly, claim the reliefs you are entitled to, and save you valuable time.
Looking for the best personal tax accountant in the UK? The right accountant can help with Self Assessment tax returns, landlord tax, sole trader accounts, tax planning, HMRC enquiries, and ongoing personal tax advice. In this guide, we compare nine trusted firms to help you choose the one that suits your needs.
One thing has changed for 2026 that makes choosing the right accountant more important than ever: Making Tax Digital for Income Tax (MTD ITSA) is now mandatory for many sole traders and landlords — see the dedicated section below.
In this blog, you’ll learn what each firm offers, who they are best suited for, how to choose the right accountant, and answers to common questions people ask before hiring a tax professional.

Each of these firms offers personal tax services, but they are designed for different types of clients. Some focus on digital tax filing, while others provide a more personal service with ongoing advice. If you want support that goes beyond filing a tax return, it is worth choosing an accountant who understands your financial goals as well as your tax obligations.

Making Tax Digital for Income Tax (MTD ITSA): What’s New in 2026
From April 2026, Making Tax Digital for Income Tax became mandatory for sole traders and landlords with qualifying income over £50,000. This threshold drops to £30,000 from April 2027. Under MTD ITSA, instead of filing one annual Self Assessment return, you must:
- Keep digital records of income and expenses using MTD-compatible software
- Send quarterly updates to HMRC throughout the year
- Submit a final declaration after the tax year ends, replacing the old SA100 process for those in scope
If you’re a sole trader or landlord approaching either threshold, this is one of the most important reasons to work with an accountant now rather than at the next filing deadline — most of the firms above, including MyIVA, can set you up on MTD-compatible software and handle quarterly submissions on your behalf. For the official rules, see GOV.UK’s MTD for Income Tax guidance.
Key Self Assessment Deadlines for the 2025–26 Tax Year

- 31 October 2026 — paper tax return deadline
- 31 January 2027 — online tax return deadline and deadline to pay any tax owed

How to Choose the Right Personal Tax Accountant
Finding the right personal tax accountant is not only about the price. You also want someone you can trust with your finances. A good accountant should make tax easier to understand, answer your questions without using confusing language, and be there when you need advice. Spending a little extra time comparing your options now can save you a lot of stress later.
Choose an accountant who understands your situation
Every person’s tax affairs are different. A landlord will have different tax needs from a sole trader or a freelancer. Before you decide, check whether the accountant has experience working with people in a similar position to yours. They are more likely to understand the rules that apply to you.
Check what services are included
Some accountants only help with Self Assessment tax returns. Others can also look after bookkeeping, VAT, payroll, Corporation Tax, and tax planning. If you think your needs may change in the future, choosing an accountant who offers a wider range of services can be a sensible decision.
Ask about their fees
Always ask how much the service will cost before you sign up. Some accountants charge a fixed fee, while others charge based on the work involved. Knowing the cost in advance helps you plan your budget and avoids any surprises later.
Read reviews from other clients
Client reviews can tell you a lot about an accountant. Look for comments about how easy they are to contact, whether they explain things clearly, and if they meet deadlines. Good reviews from real clients can give you extra confidence before making your choice.
Make sure they are easy to talk to
Tax rules can be confusing, especially if you are filing a return for the first time. A good personal tax accountant should explain everything in plain English and make sure you understand what is happening. You should feel comfortable asking questions without worrying that they are too basic.
Think about support throughout the year
Many people only contact an accountant when their tax return is due. However, having someone you can speak to during the year can be just as helpful. They can answer questions, give advice before you make financial decisions, and help you avoid problems before they happen.
The best personal tax accountant is someone who gives you confidence that your taxes are being handled properly. Take your time, compare a few options, and choose a firm that offers the right mix of experience, support, and value for your needs.
FAQs: Frequently Asked Questions
How much does a personal tax accountant cost in the UK?
Fees vary depending on your circumstances. A straightforward Self Assessment tax return may cost less than ongoing monthly accounting support. Always ask for a clear quote before you agree to any work.
Is it cheaper to file a one-off tax return or use a monthly accountant?
If your finances are simple, a one-off tax return may cost less. However, monthly support can provide year-round advice that may help reduce mistakes and improve tax planning.
Do I need a personal tax accountant if I’m a sole trader?
It is not a legal requirement, but many sole traders use a personal tax accountant to save time, claim allowable expenses correctly, and avoid filing errors.
Can a personal tax accountant help with an HMRC enquiry or investigation?
Yes. An experienced accountant can deal with HMRC on your behalf, explain what information is needed, and help you respond correctly.
Is it better to file my tax return myself or use an accountant?
If your income is straightforward, filing it yourself may be suitable. If you have multiple income sources, rental income, or want to reduce the risk of mistakes, using an accountant is often the better option.
Conclusion
Choosing the right personal tax accountant is an investment in your financial peace of mind. A good accountant helps you meet HMRC deadlines, claim the right allowances, and avoid mistakes that could cost you money later.
