There are a number of circumstances when you will need to let HM Revenue & Customs (HMRC) know about changes at home. This guide explains the most common changes, what you need to do and who you need to contact.
On this page:
If you start living with a partner and you receive tax credits, you must let the Tax Credit Office know within one month. This will make sure you receive the right amount of tax credits.
If you are getting Child Benefit and you move in with a partner, you need to let the Child Benefit Office know as soon as possible.
If you get married or form a civil partnership, you should let HMRC know so they can keep your records up to date.
You can let HMRC know by using the HMRC email service.
Alternatively you can phone or write to HMRC.
If you separate or divorce and change your name, address or marital status as a result, you should let HMRC know so they can keep your details up to date.
You can use the email service to let them know about a change of name or address (as a result of separating, divorcing or you or your partner moving out) - or you can phone them or write to them.
If you get tax credits, you must let the Tax Credits Office know within one month. You may have to make a new claim as a single person.
You should let the Child Benefit Office know as soon as possible - particularly if you are no longer paying money towards looking after a child.
If you're having a new baby, you should claim Child Benefit as soon as possible once your child is born. Otherwise you may miss out on payments you're entitled to.
You may also qualify for tax credits when you have your baby. And if you're already receiving tax credits, you may be entitled to more money. You should let the Tax Credit Office know as soon as you've had your baby, as claims can only be backdated for a maximum of three months.
If you or your partner get tax credits and either of you go on maternity, paternity or adoption leave, you should check to see if your tax credits will be affected.
