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:

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'.
