A substantial part of individual income tax is collected through withholding by third parties. Employers are required to withhold Article 21/26 income tax on a monthly basis from the salaries and other compensation payable to their employees. If an employee is a resident taxpayer, the amount of tax withheld should be based on the normal tax rates (as set out above). If he/she is a non-resident taxpayer, the withholding tax is 20% of the gross amount (and may be set at a lower rate under a tax treaty).

Various other payments to individuals also call for withholding tax obligations from the payers. These include, among others:

• Pension payments made by government-approved pension funds;

• Severance payments;

• Old-age security saving payments from BPJS Ketenagakerjaan;

• Fees for services;

• Prizes/awards.

Typically the amount of tax withheld from these types of income (Article 21 income tax) is based on normal tax rates as set out above.

The tax withheld on fees for non-employee individuals
and certain professionals, such as lawyers, notaries, accountants, architects, doctors, actuaries and appraisers, are required to be calculated based on 50% of the gross income at the prevailing rates.

Interest earned on severance payments transferred to a manpower severance pay management board is subject to a final tax of 20% if the board is a bank, or to a 15% withholding tax under Article 23 income tax in other cases.
