Engagement letters for tax practitioners.

Engagement letters for tax practitioners, issued in April 2020, provides guidance to tax practitioners about engagement letters for tax work. These have been updated in 2021 for new VAT schedules for Great Britain and also new VAT schedules for Northern Ireland following Brexit.

The engagement letter pack comprises the following documents:

  • covering letter
  • schedules for various specific services
  • standard terms and conditions of business
  • privacy notice
  • cancellation notices for consumers.

This has been supplemented by an example subcontractor agreement that can be used by a practitioner acting as a subcontractor to a regulated firm engaged in public practice.

You can hear more about the importance of engagement letters in client engagement in this webinar.

New MTD for Income Tax schedule (June 2025)

A new MTD for Income Tax schedule has been published by the Joint Professional Bodies Engagement Letters Working Party (AAT, ACCA, ATT, CIOT and STEP) and is available below. This schedule can be used by members with clients who must comply with the requirements of MTD for Income Tax, and, in relevant cases, is to be used instead of the existing Personal Tax – Sole Traders and Property Income schedule included in the main engagement letter guidance.

ACCA's suite of engagement letters can also be accessed here.
