Tax codes: Tax code declaration

Using the tax code declaration

Employee and contractor responsibility

Employees, and contractors subject to schedular payments (formerly withholding payments) must complete a Tax code declaration (IR330) as soon as they start working for you.

What will the tax code be?

The employee or contractor's tax code may be a:

• main tax code
• secondary tax code
• special tax code
• code for casual agricultural employees
• code for election day workers
• code for schedular payments - this is for contract work, not for salary or wages.

See "Find out more" below to find out details on these codes.

What if the employee doesn't complete the IR330?

If an employee fails to fully complete the IR330, you must deduct PAYE at the no-notification (formerly no-declaration) rate.

What if the self-employed contractor doesn't complete the IR330?

If a self-employed contractor subject to schedular payments (formerly withholding payments) fails to fully complete the IR330, you must deduct tax at the no-notification rate.

What if my employee chooses the wrong tax code?

If we identify that any of your employees has chosen an incorrect tax code we will:

• write to you, telling you which employees are using an incorrect tax code
• advise you what the correct code should be.

You will need to:

• change their tax code to the code indicated in our letter
• deduct tax based on the new tax code.
