# Tax Accountants UK

Pick My Accountant (https://pickmyaccountant.co.uk/services/tax-accountants/): Tax Accountants UK — Compare UK tax accountants from £39/month — self assessment, corporation tax, capital gains and tax planning. Get matched with a qualified adviser. A tax accountant prepares returns, claims reliefs, and deals with HMRC — they do not sell a guaranteed refund. Ongoing personal tax support typically runs £39–£149 a month on our editorial benchmarks; a one-off Self Assessment commonly costs £150–£350. Skip a planning retainer if you only need a straightforward SA100. Live criminal investigations need a solicitor, not a comparison table.

A tax accountant makes sure you pay the right amount of tax — not a penny more. From self assessment and corporation tax to capital gains, tax planning and HMRC enquiries, a qualified adviser spots the reliefs and allowances a generalist might miss. Look for regulated qualifications — ICAEW or ACCA for accountancy, CIOT for pure tax advice — and check who will actually handle your work before engaging.

## Who this is not for

Skip a tax-planning retainer if you only need a straightforward self assessment — buy that product, not a CIOT-level engagement. Skip this page if you are in a live criminal investigation; you need a solicitor, not a comparison table.

## What does a tax accountant actually do?

They prepare and file returns, calculate what is due, claim reliefs, and deal with HMRC. They do not sell a guaranteed refund. Skip a monthly tax adviser if your only job is a simple SA100 you will file on time yourself.

ICAEW and ACCA cover accountancy; CIOT (Chartered Tax Adviser) is the pure tax badge. Ask who will actually touch the file. Enquiry defence is usually a separate letter, not the monthly package.

## How much does a tax accountant cost in the UK?

Ongoing personal tax support typically runs £39–£149 per month on our editorial benchmarks; one-off self assessment commonly costs £150–£350. Advisory projects are quoted as a fixed fee. Confirm whether HMRC correspondence is included.

Capital gains, overseas income and trust work sit above these ranges. Compare written scopes, not hourly rumours. We never invent a fee when a listing has not published one.

## Tax accountant vs tax adviser — what is the difference?

In practice the terms overlap. Look for regulated qualifications — ICAEW or ACCA for accountancy, CIOT for pure tax specialism — and ask who will actually handle your work. A job title on a website is not a practising certificate.

Anyone can advertise tax help. The register is how you tell qualified from not. For accountancy filings you still want someone who can file, not only advise.

## Can a tax accountant help me pay less tax?

They can claim reliefs and allowances you are entitled to, and time transactions where the law allows. They cannot invent deductions or promise a refund before seeing records. Anyone who guarantees a saving on a sales call is selling, not advising.

Legitimate planning is documented and matches your facts. Aggressive schemes that sound too neat are how people buy an enquiry. If you want less tax, start with complete records, then reliefs on GOV.UK, then advice.

## When do I need a tax specialist rather than a general accountant?

When you have capital gains, foreign income, trusts, a live HMRC enquiry, or a one-off event (sale of a business, share scheme, leaving the UK). A monthly small-business package is the wrong product for those. Say the event on the comparison wizard.

General accountants still file most SA100s and CT600s well. Specialists earn the extra fee on the unusual pages. Do not pay CIOT rates for a vanilla sole-trader return.

## What should a tax engagement letter include?

The returns they will file, the tax years covered, whether HMRC mail is included, and what happens if an enquiry starts. Hourly rates for extras should be written down. A verbal “we'll look after you” is not a scope.

Authorise them as your HMRC agent only after you have signed. You can cancel the agent authority if you switch firms.

- Usually in: named returns, submission, basic correspondence
- Often extra: enquiry defence, CGT on a sale, overseas pages, trusts

## How should I choose a tax accountant?

Match the qualification to the work, check the public register, then compare fixed fees on the same list of returns. Interview who will actually do the work. Skip guaranteed refunds and anyone who will not put the scope in writing.

Online tax boutiques can be excellent for filings. A local meeting still helps for a sale or an enquiry. Three quotes are enough.

1. List every income stream and any live HMRC letter
2. Check ICAEW, ACCA, AAT, ICAS or CIOT for the shortlist
3. Compare written fees for the same returns
4. Ask what an enquiry would cost before one starts

## FAQs

**Q: What does a tax accountant actually do?**
A: Prepares and files tax returns, calculates liabilities, claims reliefs and allowances, advises on timing and structure, and deals with HMRC on your behalf — including compliance checks when that is in the letter.

**Q: How much does a tax accountant cost?**
A: Ongoing personal tax support typically runs £39–£149 per month depending on complexity; one-off self assessment returns commonly cost £150–£350. Advisory work is usually quoted as a fixed fee in advance.

**Q: Tax accountant vs tax adviser — what's the difference?**
A: In practice the terms overlap. Look for regulated qualifications — ICAEW or ACCA for accountancy, CIOT (Chartered Tax Adviser) for pure tax specialism — and ask who will actually handle your work.

**Q: Can a tax accountant guarantee a refund?**
A: No honest one can before seeing your records. Refunds depend on your facts and current law. Treat a guaranteed refund as a sales tactic.

**Q: Are accountant fees tax deductible?**
A: Business accountancy fees are usually an allowable expense for the business. Personal tax-return fees are often not deductible against that personal income. Confirm the current treatment with your adviser — do not copy a forum answer.

**Q: Who should I call if HMRC opens an enquiry?**
A: The accountant who filed the return, or a tax specialist if the enquiry is larger than their letter covers. Criminal investigations need a solicitor. Do not ignore the letter.
