PPh 21 TER Withholding for Foreign Employees in Indonesia
Employees in Indonesia have income tax withheld by their employer under Article 21 of the Income Tax Law (PPh 21). From the tax period of January 2024, the method changed to the Tarif Efektif Rata-rata (TER, effective average rate) system under Government Regulation 58/2023 and Finance Minister Regulation PMK 168/2023 [1][3].
How TER works
Under the older method, employers annualised each month's salary, subtracted deductions and the personal allowance, and applied the progressive brackets. TER simplifies this. The employer looks up a monthly TER table based on the employee's family status category and gross monthly income, then multiplies the rate by gross income. The tables are in the regulation and are divided into categories according to the personal allowance (PTKP) status [1].
For permanent employees (pegawai tetap), the TER is used for each tax period from January to November. In December, or the last tax period when the employee leaves, the employer recalculates the tax for the whole year using the Article 17 progressive rates, then subtracts what was withheld in earlier months [1][2]. If TER withholding was lower than the real annual tax, the employee pays the difference in December. If it was higher, the excess is netted off.
Why employees feel it
- Monthly take-home pay may change. In months with bonuses, TER applies to the larger gross amount and may bring a higher rate.
- December can be a surprise. Because the annual tax is recalculated at the end, December take-home can be noticeably lower or higher than in other months.
- Overall liability is not reduced. TER is a withholding method for convenience. The final annual tax is still computed under the brackets in the annual return (SPT Tahunan).
Foreign employees
TER is designed for employees who are tax residents and receive a regular salary. A foreign national who has met the residency test, generally more than 183 days in Indonesia within 12 months or an intention to reside, is treated as a resident taxpayer. Non-residents working for short periods are typically subject to a different withholding, often 20% under Article 26 on Indonesian-source income, and are outside the TER system.
Employers need to confirm the status when the employee joins, because a foreigner who starts as a non-resident may become resident later in the year and need different treatment in the following withholding periods.
Practical advice for employers and employees
- Give HR your correct NPWP and PTKP status when you start work. Incorrect status leads to the wrong TER category.
- Ask for the withholding slip (bukti potong) each year and compare it to your payslips.
- Plan for December. If you expect a bonus, relocation payment or allowances, estimate the true-up in advance.
- Check whether you have other income, such as rent or freelance work, that must be added in the annual return.
- If your employer covers your tax (a net or tax-grossed-up package), check how the allowance is calculated, because it can itself be taxable.
Employers should also verify that payroll systems use the latest tables and that tax is reported through the correct channels: e-Bupot 21/26 and DJP Online (Coretax from 2025).
