IRD secondary tax codes are chosen from your estimated total annual income, not only the second job income. The selected code sets the flat withholding rate for the secondary income source before ACC levies.
Preguntas Frecuentes
When do I use a secondary tax code in New Zealand?
Use a secondary tax code when you receive taxable income from more than one source, such as a second job, benefit, pension, ACC payment, or paid parental leave.
What are the current NZ secondary tax codes?
The current secondary codes are SB, S, SH, ST, and SA. The code depends on your estimated total annual income from all sources.
Are secondary tax rates before ACC?
Yes. IRD lists secondary tax rates before ACC levies, so ACC deductions may still apply separately to liable earnings.
What if I have a student loan?
If you have an NZ student loan, the secondary tax code normally has SL added, such as S SL or SH SL.
Can IRD change my tax code?
Yes. IRD may ask your payer to change your tax code if it appears unsuitable, to help avoid an end-of-year bill or overpayment.
