Where to find your tax code

If you're employed or between jobs

You'll find your tax code on your P45 (given to you by your employer when you stop working for them). This is why it's very important to give this to your new employer when you change jobs.

If you've lost your P45 and want to find out your tax code contact your Tax Office and give them your National Insurance number and tax reference number.

You'll also find your tax code on your 'PAYE Coding Notice' sent to you by your Tax Office usually before the start of each tax year. (It may also be sent to you at other times if something has changed - for example, if you’ve started receiving a new source of income or a new company benefit or your entitlement to age-related or other allowances has changed.)
