Payroll hub
Payroll, social security and employee tax hub
Every payroll run ends at three counters: the Revenue Department for tax withheld, the Social Security Office for contributions, and the workmen's compensation fund for the annual rate. This hub gathers the calculations, the due dates, the records to retain, and the cases that trip employers up — bonuses, overtime, taxable benefits, and hiring foreign staff.
