Tax codes for common situations
You only have 1 main income, which is your highest income source. All other income is secondary income. Any tax code you select is based on the type and level of your expected annual income.
Also, you may need to choose a new tax code if things change during the year. For example:
- you take out a student loan or pay it off
- you have a change in expected annual income
- you change jobs or start a second job.
If you’re getting PPL you choose a tax code just as you would with any other source of income.
If you have a student loan, you choose a tax code that tells your employer to deduct your repayments. Once you’ve paid off your loan, you need to choose a new tax code and tell your employer what it is.
If you’re getting ACC, you choose a tax code just like with any other source of income. Depending on how much you’re getting, ACC could be your main or secondary source of income.
Your tax code with your employer may change depending on how much ACC pays you.
