Criminal Investigators within the Fraud Investigation Service are on the front line in the fight against criminals, fraudsters and tax cheats. As well as gathering and acting on intelligence, our Investigators arrest suspects, gather evidence to prosecute them in court and recover losses by taking money and assets away from criminals.

What could I be doing?

After receiving comprehensive training, you can expect a combination of desk-based investigations, and time spent in the field. You’ll help gather vital evidence on individuals and organised crime groups and prepare cases for court. You will carry out arrests and searches of houses, cars and business premises. You’ll attend court yourself as well, both to give evidence and to obtain orders and warrants. As your career progresses there may be opportunities to specialise in other areas, such as financial recovery or surveillance.

Do I have the right skills or qualifications?

You may have an investigative or intelligence background, or else a naturally inquisitive mind with strong analytical skills, attention to detail and verbal and numerical aptitude. You’ll have good judgement, problem-solving & decision-making skills. You’ll have the ability to work as part of a team, to build and maintain effective working relationships. You’ll be resilient and prepared to deal with challenge or confrontation.

You will have high level of integrity and maintain the highest professional standards required for the role. You should have a keen interest in becoming an integral part of an organisation that is focused on collecting the tax that funds the UK’s vital public services.

This role is not always a standard 9-5 position. You will be expected to work flexibly; this may involve some evenings and weekends, sometimes at short notice. HMRC pay a Flexibility Payment to recompense for this which enables different levels of flexibility to be accommodated.


Training plays a big part in our work here. As well as core training and a structured induction, your role-specific training could include chain-of evidence, search warrants, taking witness statements, giving evidence and more. We offer advanced training in tradecraft, intelligence practice and methodology, case building skills and source handling, as well as practical skills around arrests, searches, surveillance and much else.
