How to change accountant without the stress

By AF Coopers & Co · Last reviewed September 2026

The short answer: changing accountant is easier than most people expect. You choose your new accountant, they take care of contacting your old one, and you sign a few authorisations. You can change at any time of the year.

When people decide to change

  • Deadlines are missed, or they hear about them too late
  • Fees are unclear or change without warning
  • Questions go unanswered for days
  • The business has outgrown the service, or needs help the accountant does not offer
  • The accountant does not work with the software the business wants to use

The steps

  1. Choose your new accountant. Ask what is included, who you will deal with and how fees work. Our guide on what accountants charge lists good questions.
  2. Agree the work in writing. You will receive an engagement letter setting out the services and the fee.
  3. Your new accountant contacts your old one. They ask for the information they need to take over. You do not have to chase this yourself.
  4. Authorise your new accountant. You will be asked to give permission for them to deal with HMRC on your behalf, and if you have a company, to file with Companies House.
  5. Pass on your records. This includes your last accounts and tax returns, payroll and VAT records, and any letters from HMRC.
  6. Tell your old accountant you are leaving, and settle any fees that are properly owed.

Choosing the timing

You can change at any time. Many people choose to switch just after a deadline, so nothing is in progress, but if a deadline is close your new accountant can pick it up. Do not wait until the last moment.

Common questions

Can I change accountant part-way through the year?

Yes. Your new accountant reviews where things stand and carries on from there.

Will I lose any records?

You should get your records back from your previous accountant. We help you list what you need so nothing is missed.

Do I have to tell HMRC?

You will be asked to authorise your new accountant to act for you. We guide you through the steps.

General information only, not personal advice. Tax rules, rates and thresholds change, so check gov.uk or speak to us about your own situation.
