Work out your tax code
You need to fill in a Tax code declaration (IR330) form when you start a new job, or if you have a change in your circumstances that will affect your tax and/or your student loan repayments.
Work out your correct tax code here.
Changes in your circumstances include:
- starting a different job
- having more than one job, so your total annual income moves into a different tax bracket (see "Definitions" below)
- having a student loan, so you need to start making repayments because your annual income goes over the student loan repayment threshold (see "Definitions" below), or
- having paid off your student loan, so you no longer need to make repayments.

Special tax code/student loan special repayment deduction rate
A special tax code is a tax deduction rate worked out to suit your individual circumstances. If you usually receive a large income tax/student loan bill or refund, or want to pay off your student loan faster, it's a good idea to apply for a special tax code or deduction rate. This ensures you pay the right amount of tax or student loan deductions.
Student loan repayment threshold
If you have a student loan you must begin repaying your student loan as soon as your total annual income (from 1 April to 31 March) goes over the student loan repayment threshold.
