Resident taxpayers and Indonesian PEs of foreign companies have to settle their tax liabilities either by direct payments, third party withholdings, or a combination of both. Foreign companies without a PE in Indonesia have to settle their tax liabilities for their Indonesian-sourced income through withholding of the tax by the Indonesian party paying the income.

Monthly tax instalments (Article 25 income tax) constitute the first part of tax payments to be made by resident taxpayers and Indonesian PEs as a prepayment of their current year Corporate Income Tax (CIT) liability. A monthly tax instalment is generally calculated using the most recent Corporate Income Tax Return (CITR). Special instalment calculations apply for new taxpayers, finance lease companies, banks, state-owned companies, listed companies and other taxpayers with periodical reporting requirements.

The tax withheld by third parties on certain income (Article 23 income tax) or tax to be paid in advance on certain transactions (e.g., Article 22 income tax on imports) also constitute prepayments for the current year CIT liability of the income recipient or the party conducting the import (refer to pages 31-32 for income items subject to Article 23 income tax and pages 25-30 for transactions subject to Article 22 income tax).

If the total amount of tax paid in advance through the year (Articles 22, 23, and 25 income taxes) and the tax paid abroad (Article 24 income tax) is less than the total CIT due, the taxpayer has to settle the shortfall before filing its CITR. Such a payment is referred to as Article 29 income tax.

Certain types of income earned by resident taxpayers
or Indonesian PEs are subject to final income tax. In this respect, the tax withheld by third parties (referred to as Article 4(2) income tax) constitutes the final settlement of the income tax for that particular income (refer to pages 30-31 for income items subject to final income tax under Article 4(2) income tax).

For foreign companies without a PE in Indonesia, the tax withheld from their Indonesia-sourced income by the Indonesian party paying the income (Article 26 income tax) constitutes a final settlement of their income tax due (refer to pages 32-33 for income items subject to Article 26 income tax).
