IDG60150 - Procedure for disclosing to others (government): Anti- Terrorism, Crime and Security Act 2001 (ATCSA)


HMRC may disclose information to certain enforcement authorities and intelligence agencies through a legal gateway provided by section 19 of the Anti-Terrorism, Crime and Security Act 2001 (ATCSA).

If you are in the department’s Criminal Investigation, Detection or Risk & Intelligence Service directorates (‘Enforcement’) and

  • there is a time critical need for information, or
  • you are in a joint working situation with the recipient of the information, or
  • you have an established working relationship with the recipient of the information

then you should follow the procedure outlined at IDG60170.

For all other disclosure situations, including requests from law enforcement agencies for information or pro-active disclosures that you wish to make, you should follow the procedure at IDG60190.
