Main income
Your main or highest PAYE income starts here
For most employees, the main or highest PAYE income follows the main-income branch. That usually ends in M or M SL.
ME path
ME and ME SL need extra conditions
You only use ME or ME SL if you are a New Zealand tax resident, your annual net income is between NZ$24,000 and NZ$70,000, and no exclusion applies.
Secondary income
Second jobs and lower PAYE incomes use secondary codes
If this income is not your main or highest PAYE income, the usual result is a secondary code such as SB, S, SH, ST, or SA. Add SL if student loan deductions also apply.
Special cases
Some people branch off early
Codes such as CAE, EDW, NSW, and STC sit outside the regular main or secondary path and should be checked first.
Contractors
Contractor and schedular payments usually use IR330C
If you are being paid as a contractor or under schedular payments, you normally move to the IR330C path instead of choosing a standard employee tax code.
Investment income
Dividends and interest usually use RWT
Investment income normally does not use a standard IR330 employee code. It usually follows resident withholding tax, or RWT.
