How to check employment status

Posted on 6th May 2025 by Streets - Employment & Payroll

HMRC’s CEST tool gets a revamp from 30 April 2025, with clearer questions and updated guidance to help users decide employment status for tax—plus stronger backing from HMRC.

In a Written Ministerial Statement delivered on 28 April, the Exchequer Secretary to the Treasury announced a series of administrative and simplification measures designed to advance the government’s commitment to modernising the tax and customs systems.

Among these measures is an important update to HMRC’s Check Employment Status for Tax (CEST) digital tool, set to take effect from 30 April 2025. The CEST tool plays a key role in helping users determine whether a worker should be treated as employed or self-employed for tax purposes across both the private and public sectors.

The forthcoming changes aim to improve usability and clarity, making it more accessible and efficient for individuals and organisations alike. In conjunction with these technical improvements, HMRC will issue updated guidance to support users in navigating the revised set of questions, ensuring they are better equipped to use the tool correctly and confidently.

The service provides HMRC’s view as to whether IR35 legislation applies to a particular engagement and whether a worker should pay tax through PAYE as well as helping to determine if the off-payroll working in the public sector rules apply to a public sector engagement. HMRC has confirmed that it will stand by the outcome produced by the CEST tool, provided that the information entered is accurate and complete. However, HMRC will not stand by the results of contrived arrangements and designed to get a particular outcome from the service.

The service can be used by a variety of users, including:

Workers providing services;
Individuals or organisations engaging workers; and
Employment agencies placing workers with clients.
