\text{Net ACC Payout} = (\text{Gross ACC} - \text{Abatement}) - \text{PAYE Tax} - \text{KiwiSaver} - \text{Student Loan}Under the Accident Compensation Act 2001, ACC pays 80% of pre-injury gross earnings from day 8 of incapacity up to the statutory cap of $2,280.91 gross/week. If the worker returns to work part-time, compensation abates dollar-for-dollar once combined earnings exceed 100% of pre-injury wages. Crucially, ACC payments are exempt from the 1.60% ACC Earner's Levy.

If it is a work-related injury, the employer must pay 80% of earnings for the first week. If it is a non-work injury, the employee uses sick leave or annual leave for the first week. ACC weekly compensation begins from day 8 onwards.
No! Unlike standard salary wages, the 1.60% ACC Earner's Levy is not deducted from ACC weekly compensation payments. Only PAYE income tax, Student Loan (if applicable), and KiwiSaver are deducted.
ACC does not immediately cut payments. Under the abatement policy, you can earn up to 100% of your pre-injury earnings between your part-time wages and ACC. Only amounts exceeding 100% of pre-injury pay reduce your ACC dollar-for-dollar.
