Indonesia PPh 21 Personal Income Tax Overview

The Indonesia PPh 21 Calculator computes personal income tax withholdings for resident and non-resident employees under Law No. 7/2021 (UU HPP). It calculates statutory progressive tax brackets from 5% to 35%, deducts non-taxable income (PTKP status from TK/0 to K/3), and determines net take-home salary in Indonesian Rupiah.

Pajak Penghasilan Pasal 21 (PPh 21) is Indonesia's progressive withholding tax levied on employment salary, wage compensation, allowances, and honorariums. Administered by the Directorate General of Taxes (Direktorat Jenderal Pajak - DJP), resident taxpayers must hold a tax ID number (NPWP) to avoid a punitive 20% withholding surcharge.
