Add up gross pay from all employers (from your payslips or myIR).
Enter all tax taken from your pay (PAYE income tax plus the ACC earners' levy). On most payslips this is the combined "PAYE" deduction. Use the total across all employers.
The NZ tax year runs from 1 April to 31 March. For most wage and salary earners, income tax and the ACC earners' levy are deducted automatically through PAYE. After 31 March, IRD reconciles what you earned against what was deducted and issues an automatic income tax assessment. If too much was deducted you get a refund; if too little, you'll get a bill.
Refunds are usually paid between late May and July into the bank account IRD holds for you. Most people on standard salary or wages don't need to file an IR3 unless they have other income such as rental, overseas, or business income. Keeping your details current in myIR helps payments arrive on time.
