Before you start   

To check your income tax, you will need to sign in to your personal tax account using your Government Gateway user ID and password.

If you do not have a personal tax account 

You need a Government Gateway user ID and password to set up a personal tax account. If you do not already have a user ID you can create one when you sign in for the first time.

You will need your National Insurance number or postcode and two of the following:

• a valid UK passport 
• a UK photo card driving licence issued by the DVLA (or DVA in Northern Ireland) 
• a payslip from the last three months or a P60 from your employer for the last tax year 
• details of a tax credit claim if you made one  
• details from a Self Assessment tax return (in the last two years) if you made one  
• information held on your credit record if you have one (such as loans, credit cards or mortgages)  

If you cannot create a personal tax account 

Contact HMRC (external link) for advice if you cannot create a personal tax account. 

You can also estimate how much Income Tax you should pay this year (external link) without signing in.
