TER (Effective Average Rate)
TER (Tarif Efektif Rata-rata / Effective Average Rate) is the method for calculating PPh Article 21 withholding effective January 1, 2024 under Ministry of Finance Regulation No. 168/PMK.03/2023. TER replaces the more complex monthly progressive rate method with a simpler, more transparent calculation. There are two types of TER: (1) Monthly TER, used for January through November of each year, (2) Annual TER (using Article 17 para. 1 rate), used for December as the final tax settlement for the year. TER is divided into three categories based on the taxpayer's PTKP (non-taxable income) status: Category A: Single with TK/0, TK/1, or Married K/0 (basic/entry status), Category B: TK/2, TK/3, Married K/1, or K/2 (intermediate status), Category C: Married K/3 (highest status). The complete TER table with detailed rates for each income range is in the Annex to PMK 168/2023. Each month, withholding agents use this table to calculate PPh 21 based on salary level and employee PTKP status.

Article 21 Income Tax (PPh 21)
PPh Article 21 is the income tax on wages, salaries, honoraria, allowances, and other payments received by individual residents in connection with work, employment, services, or activities (Article 21 para. 1, Income Tax Law). Governed by Article 21 of Law No. 36/2008 on Income Tax (UU PPh) and Ministry of Finance Regulation No. 168/PMK.03/2023. Effective January 1, 2024, withholding uses the Effective Average Rate (TER) method, which is simpler than the previous progressive rate method. The withholding agent (usually the employer, treasurer, or payment maker) is obligated to: (1) Calculate and withhold PPh 21 from each income payment, (2) Remit to the state treasury by the 10th of the following month (Article 21 para. 11, UU PPh), (3) File the monthly tax return by the 20th of the following month (Article 21 para. 12, UU PPh), (4) Issue Form 1721-A1 (withholding certificate) by end of January of the following year. The TER rate depends on the taxpayer's PTKP status (TK, K, K/I) and income level, ranging from 0% to 30% progressively per category.

Performance Allowance (Tunjangan Kinerja / Tukin)
A performance allowance, commonly known by its Indonesian abbreviation tukin, is a supplementary income component on top of base salary paid to civil servants and government agency staff, calibrated to organizational and individual performance. For the Directorate General of Taxes (DGT), the framework comes from Presidential Regulation Number 37 of 2015 and technical rules in Ministry of Finance regulations, most recently amended by PMK 39 of 2026 which revised PMK 211/PMK.03/2017. The DGT allowance is computed using the formula: a constant times ((60% x organizational performance score) + (40% x individual performance score)) times the allowance table by position grade. The allowance is subject to income tax and withheld under PPh Article 21 by the institutional treasurer.
