Tell HMRC about a change to your personal details
Gender change
HM Revenue and Customs (HMRC) is usually told automatically when you change gender legally by applying for a Gender Recognition Certificate.
Tell your employer at the same time - they must update your payroll records and National Insurance contributions.
HMRC will:
- update its records with your gender and any name change
- tell the Department for Work and Pensions (DWP)
- restrict your records so only specialist staff at HMRC and DWP can access them
- hand your tax affairs to HMRC’s Public Department 1
Once you get a letter confirming your records have moved, you can contact Public Department 1 with questions about your tax or National Insurance.

Tell HMRC yourself
You can write to Special Section D to tell HMRC:
- about your legal gender change
- about your name change only if you did not change gender legally
- if you do not want them to restrict your records
Include your National Insurance number, and your original Gender Recognition Certificate if you’ve changed gender legally.
