IR330 Tax Code Declaration: Who Qualifies and What You Get

Learn how to declare your tax code correctly to ensure the right amount of tax is taken from your salary each payday.

The IR330 Tax Code Declaration is a formal way to tell your employer which tax code you should use so they can deduct the correct amount of tax from your pay.

Who it's for

This is for any employee who is starting a new job or whose personal circumstances have changed, requiring a change to how much tax is withheld.

What you get

By completing this declaration, you ensure that the correct amount of tax is deducted from your salary or wages. This helps prevent you from paying too much or too little tax during the year.

What it costs you

There is no monetary cost to this process. It only requires the time and effort needed to fill out the required paperwork when you start a new position.

The catch to know

The biggest risk is using the wrong tax code. If you select an incorrect code, you might find yourself facing an unexpected tax bill at the end of the financial year.

How to apply

  1. Obtain the declaration form from your new employer.
  2. Review your personal circumstances to determine your correct tax code.
  3. Complete the form accurately.
  4. Submit the completed form to your employer's payroll department.
