Before you start to complete the online form it's very important that you have all of the information below to hand. Some of this information is used to confirm your identity - because of this, the information you provide must be accurate and complete.
Over 80% of problems with information held by HMRC are caused by individuals and employers giving incorrect names, dates of birth and National Insurance numbers. It’s important to get this information right so that you are paying the correct amount of Income Tax and National Insurance to protect your entitlement to State Pension and certain other benefits.
Full name, including any middle name(s) - always provide your correctly spelled full names, making sure that your forename(s) and surname are in the correct order.
Date of birth - always provide your correct date of birth. If you give an incorrect date of birth it might affect your entitlement to certain benefits.
National Insurance number - always use your correct National Insurance number. Do not make a number up or use someone else's. If you have lost your National Insurance number or can't remember it, you might be able to find it on official paper work like:
If you still can't find your number, you can ask HMRC to confirm it by following the link below.
You must provide your current employer's PAYE reference number. You'll find this on your wage slip or on your P60 form unless you have recently changed your employer.
You must also provide one of the following:
This information is very important because it helps HMRC to keep your personal details safe. If they can't be sure who you are they will not accept your new details by email.
You'll also need to provide:
If you need to report a legal gender change this can only be done in writing accompanied by the appropriate Gender Recognition Certificate (unless you have elected for the Gender Recognition Panel to directly notify HMRC).
You'll also need to provide:
If you want HMRC to contact you at a different address - your 'nominated correspondence address' - you'll need to tell them the full address and the date from which you want them to use it.
It should only take you around ten minutes to complete the form - but please make sure you have all the details you require to hand before you start as it will save you time when filling in the form. See the sections 'Information you'll need to report the change', 'If you want to tell us about a change of name' and 'If you want to tell us about a change of address' above.
When you've got the information you need to hand, use the link below to start filling in the form.
HMRC will update your change of name and address in the following services:
In addition the change you have reported will also be notified to:
HMRC will send you an email straight away to tell you that they've received your change in personal details. After that, if they need any more information from you they'll ask you for it in a secure email and you'll usually be able to send the details back to them by email.
When HMRC’s got all the information they need they'll let you know they've changed your personal details and, if appropriate, when you can expect to get a new tax code.
If, for any reason, HMRC can't identify you against their records they will let you know and ask you to either phone or write to them about your change.
If you've told HMRC that you've changed your name they may need to ask you to send them certain legal documents before they can go ahead and make the change. If they do need you to do this they will tell you by email.
You will not be sent a new National Insurance number card. You don't need to have a card - it's the number that's important.
This form only allows you to update your personal change of name and address.
If you change your business name or address you will have to notify HMRC separately.
You can find out how to do this in the guidance 'Reporting changes to HMRC - businesses'.
