What It Does

Run Australian payroll in Odoo. For each payslip the module computes the ATO PAYG withholding using the Schedule 1 (NAT 1004) coefficient formula w = a×x − b on the weekly-equivalent earnings, with separate scales for employees who have and have not claimed the tax-free threshold. It computes the Super Guarantee (12% of Ordinary Time / Qualifying Earnings) with the quarterly maximum contribution base pro-rated per pay for pay dates up to 30 June 2026 and the annual Payday Super maximum contributions base from 1 July 2026, optional annual leave loading (17.5%), and net pay. Weekly, fortnightly, monthly and quarterly pay cycles are supported.
