Tell HMRC about a change to your personal details
Printable version
1. Change of name or address
You need to tell HM Revenue and Customs (HMRC) if you’ve changed your name or address. How you contact HMRC depends on your situation.
You’ll also need to change your business records if you run a business.
If you submit a Self Assessment tax return, your details will be updated once you’ve reported a name or address change.
This guide is also available in Welsh (Cymraeg).
Tell HMRC you’ve changed your address.
Tell HMRC your name has changed. You’ll need a Government Gateway user ID and password. If you do not have a user ID you can create one when you update your name.
You can also tell HMRC that your name or address has changed using the HMRC app.
Your name will be updated automatically if you change gender.
Tax agents
If you’re a tax agent (for example an accountant), tell HMRC about a change of name or address:
2. Income changes
You must tell HM Revenue and Customs (HMRC) about changes to your taxable income.
To do this you can either:
- check your Income Tax and tell HMRC about a change
- call HMRC
If you do not, you could pay too much tax or get a tax bill at the end of the year.
What you must tell HMRC
Your employer or pension provider tells HMRC when:
- you start or finish your job
- there’s a change in the money you earn from your job or get from your pension
But you must tell HMRC about any other changes, for example when you start or stop getting:
- income from a new source, such as money from self-employment or rent from property
- taxable benefits, such as State Pension, Jobseeker’s Allowance, Carer’s Allowance or (in Scotland only) Carer Support Payment
- benefits from your job, such as a company car
- income above your Personal Allowance
- money over £85,000 from self-employment (you must register for VAT over this amount)
- lump sums from selling things you pay Capital Gains Tax on, such as shares or property that’s not your main home
- income from property, money or shares you inherit, such as dividends from shares or rent from property
If you get tax credits
Tell HMRC separately about changes that affect your tax credits.
If your spouse or civil partner dies
Tell HMRC about changes to your income after the death of your husband, wife or civil partner.
If you make Self Assessment ‘payments on account’
Tell HMRC if you expect a big decrease in income and you pay your Self Assessment tax bill in advance (‘payments on account’). HMRC may decide to reduce your payments.
After you tell HMRC
HMRC may:
- change your tax code and send you a PAYE Coding notice
- tell you to send a Self Assessment tax return so they can bill you for tax you owe
- send you a refund if you paid too much tax
3. Relationship or family changes
Tell HM Revenue and Customs (HMRC) if:
- you get married or form a civil partnership
- you divorce, separate or stop living with your husband, wife or partner
You can tell HMRC online if you’re paid a salary or pension through PAYE. If you submit a Self Assessment tax return as well, your details will be updated for both.
You’ll need:
- a Government Gateway user ID and password - if you do not have a Government Gateway user ID, you can create one when you tell HMRC online
- a National Insurance number (a temporary reference number will not work)
Tell HMRC straight away – if you do not, you could pay too much tax, or get a tax bill at the end of the year.
If you get tax credits or Child Benefit
Tell HMRC separately about changes to your relationship or family if you get:
If your spouse or civil partner dies
Contact HMRC to report:
- the death of your husband, wife or civil partner
- changes to your income after their death
4. 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.
