Some services unavailable 23 - 24 November | myIR, gateway services and our self-service phone line will not be available from 3pm Saturday 23 November to 9am Sunday 24 November while we do planned system testing. This will not affect any tax entitlements or payments scheduled during this time.

Tax codes help your employer (or whoever pays you) work out how much tax to deduct from your pay, benefit or pension. Tax rates are used to work out how much tax you need to pay on your total income for the year, from all sources.

You need to choose a tax code for each source of income and provide this to your employer or income payer.   

If your income changes, you may need to change your tax code, so you’re taxed correctly for each income source.
