# PPh 21 TER in Indonesia: Employer Withholding Guide (2026) URL: https://raintechnovation.com/resources/pph-21-ter-indonesia-employer-guide Published: 2026-10-04 Updated: 2026-10-04 Author: Veri Ferdiansyah Since 1 January 2024, employers in Indonesia withhold employee income tax (PPh 21) in two stages. From January to November, you multiply each month's gross income by a single effective rate (TER) taken from a government table. In December, you recalculate the whole year with the progressive income tax rates and withhold the difference. The monthly rate depends on the employee's tax status (category A, B or C) and on gross income, and gross income includes the BPJS premiums the employer pays and any THR paid that month. TER does not change how much tax an employee owes over a year. It changes when the tax is withheld, and it makes some months look very different from others. This guide covers the categories, what counts as gross income, the December recalculation and the filing deadlines, with worked examples at RainTech's salary tiers. ## PPh 21 at a glance Item Rule Source Who withholds The employer, as withholding agent PMK 168/2023 January to November Monthly gross income × TER rate for the employee's category PP 58/2023 December (or the month employment ends) Annual tax at Article 17 rates, minus tax already withheld PP 58/2023; PMK 168/2023, Art. 1 Gross income includes Salary, allowances, overtime, bonuses, THR, and employer-paid JKK, JKM and BPJS Kesehatan premiums PMK 168/2023, Art. 5(3) Deductions Applied only in the annual calculation: job expense (5%, maximum IDR 6,000,000 a year) and the employee's own pension and old-age contributions PMK 168/2023, Art. 10 Payment deadline 15th of the following month PMK 81/2024 Monthly return 20th of the following month PMK 81/2024 Over-withheld tax Refunded to the employee, with the annual withholding slip, by the end of the month after the final tax period PMK 168/2023, Art. 21(1) ## Step 1: find the employee's TER category Each employee's category comes from their non-taxable income status (PTKP): whether they are single (TK) or married (K), and how many dependants they claim, up to three. The status at the start of the tax year sets the category for that year. Category PTKP status Annual PTKP A TK/0 IDR 54,000,000 A TK/1, K/0 IDR 58,500,000 B TK/2, K/1 IDR 63,000,000 B TK/3, K/2 IDR 67,500,000 C K/3 IDR 72,000,000 A single engineer with no dependants is TK/0, category A. A married engineer with one child is K/1, category B. ## Step 2: work out monthly gross income The TER rate is applied to gross income before any deduction. Under Article 5(3) of Finance Minister Regulation 168 of 2023 (PMK 168/2023), gross income for a permanent employee includes: * salary and every allowance, including overtime pay; * bonuses and THR, in the month they are paid; * the JKK (work accident) and JKM (death) contributions the employer pays to BPJS Ketenagakerjaan; * the BPJS Kesehatan health contribution the employer pays. The employer's JHT (old-age) and JP (pension) contributions are not added. They are a cost to the employer, not income to the employee. The employee's own 2% JHT and 1% JP contributions are not deducted each month either; they come off only in the annual calculation. For a Tier 2 engineer on IDR 21,480,000 ($1,200) a month, at the 0.24% low-risk JKK rate that applies to most software companies: Component Calculation IDR Salary 21,480,000 JKK, employer 0.24% × 21,480,000 51,552 JKM, employer 0.30% × 21,480,000 64,440 BPJS Kesehatan, employer 4% × 12,000,000 (wage ceiling) 480,000 **Monthly gross income** **22,075,992** The contribution rates and ceilings are explained in our [BPJS guide for employers](https://raintechnovation.com/resources/bpjs-indonesia-employer-guide). ## Step 3: apply the TER rate Government Regulation 58 of 2023 (PP 58/2023) sets a table of monthly rates for each category, from 0% up to 34%. The rows below cover the salaries most tech employers pay. The full tables start at IDR 5,400,000 (A), 6,200,000 (B) and 6,600,000 (C) a month, below which the rate is 0%. Monthly gross income (IDR) Category A Monthly gross income (IDR) Category B 13,750,001 to 15,100,000 6% 13,600,001 to 14,950,000 5% 15,100,001 to 16,950,000 7% 14,950,001 to 16,400,000 6% 16,950,001 to 19,750,000 8% 16,400,001 to 18,450,000 7% 19,750,001 to 24,150,000 9% 18,450,001 to 21,850,000 8% 24,150,001 to 26,450,000 10% 21,850,001 to 26,000,000 9% 26,450,001 to 28,000,000 11% 26,000,001 to 27,700,000 10% 28,000,001 to 30,050,000 12% 27,700,001 to 29,350,000 11% 30,050,001 to 32,400,000 13% 29,350,001 to 31,450,000 12% 32,400,001 to 35,400,000 14% 31,450,001 to 33,950,000 13% 35,400,001 to 39,100,000 15% 33,950,001 to 37,100,000 14% 39,100,001 to 43,850,000 16% 37,100,001 to 41,100,000 15% 43,850,001 to 47,800,000 17% 41,100,001 to 45,800,000 16% 47,800,001 to 51,400,000 18% 45,800,001 to 49,500,000 17% 51,400,001 to 56,300,000 19% 49,500,001 to 53,800,000 18% 56,300,001 to 62,200,000 20% 53,800,001 to 58,500,000 19% 62,200,001 to 68,600,000 21% 58,500,001 to 64,000,000 20% 68,600,001 to 77,500,000 22% 64,000,001 to 71,000,000 21% Applied to RainTech's starting tiers, for a single engineer (TK/0) and a married engineer with one child (K/1): Tier Salary Monthly gross TK/0 (A) K/1 (B) Tier 1, entry IDR 14,320,000 ($800) IDR 14,877,328 6%: IDR 892,640 5%: IDR 743,866 Tier 2, mid IDR 21,480,000 ($1,200) IDR 22,075,992 9%: IDR 1,986,839 9%: IDR 1,986,839 Tier 3, senior IDR 35,800,000 ($2,000) IDR 36,473,320 15%: IDR 5,470,998 14%: IDR 5,106,265 ## The THR month Because THR is added to the gross income of the month it is paid, that month usually lands several bands higher. For the Tier 2 engineer, the month with THR has gross income of IDR 43,555,992, taxed at 16% under category A: IDR 6,968,959 withheld instead of IDR 1,986,839. For Tier 3, gross income of IDR 72,273,320 is taxed at 22%: IDR 15,900,130. Nothing is overcharged. The December recalculation settles the year. But the employee's THR payslip will show far more tax than a normal month, and it helps to explain that before it arrives. Our [THR guide for employers](https://raintechnovation.com/resources/indonesia-thr-employer-guide) covers the allowance itself and the 2027 deadlines. ## Step 4: the December recalculation In the final tax period, December or the month an employee leaves (PMK 168/2023, Article 1), you calculate the tax on the whole year at the progressive rates in Article 17 of the Income Tax Law and withhold whatever has not been withheld already. The Article 17 rates for individuals are 5% on taxable income up to IDR 60 million, 15% up to IDR 250 million, 25% up to IDR 500 million, 30% up to IDR 5 billion and 35% above that. A full year for the single Tier 2 engineer, with THR paid once and 2026 contribution ceilings: Line Calculation IDR Annual gross income 12 × 22,075,992 + THR 21,480,000 286,391,904 Job expense deduction 5% of gross, capped (6,000,000) Employee JHT contribution 2% × 21,480,000 × 12 (5,155,200) Employee JP contribution 1% × 11,086,300 ceiling × 12 (1,330,356) Net income 273,906,348 PTKP, TK/0 (54,000,000) Taxable income rounded down to the thousand 219,906,000 Tax for the year 5% × 60,000,000 + 15% × 159,906,000 26,985,900 Withheld January to November 10 × 1,986,839 + 6,968,959 (THR month) (26,837,349) **December withholding** **148,551** The JP ceiling is adjusted every March, so a real payroll uses the ceiling in force each month. The example applies the March 2026 figure to the whole year to keep the arithmetic readable. December can go the other way. If the TER months withheld more than the annual tax, the difference goes back to the employee, together with the annual withholding slip, by the end of the following month (PMK 168/2023, Article 21(1)). For a December final period, that is the end of January. ## Paying and reporting Under Finance Minister Regulation 81 of 2024, withheld PPh 21 is paid by the 15th of the month after the tax period, and the monthly return is filed by the 20th. Both run through the tax authority's Coretax system. After the final tax period, each employee receives an annual withholding slip (bukti potong A1), which they need for their own annual return. The employer registered as withholding agent does all of this. A foreign company with no Indonesian entity has no tax registration to withhold under, which is one of the reasons foreign companies hire through an [Employer of Record](https://raintechnovation.com/services/employer-of-record): the EOR is the legal employer, withholds PPh 21 each month, files the returns and issues the slips. ## Gross or net: decide before the offer A candidate who quotes a salary may mean take-home pay. Before you make an offer, agree in writing whether the salary is gross, with PPh 21 and the employee's BPJS contributions deducted from it, or net, with the employer bearing them. At Tier 2, PPh 21 alone takes about 9% of a normal month and far more in the THR month, so the difference between the two readings is large. Our [EOR pricing guide](https://raintechnovation.com/resources/eor-indonesia-pricing) shows how these costs appear on an invoice. ## FAQs ### Does TER change how much tax an employee pays? No. The tax for the year is still calculated at the Article 17 progressive rates in the final tax period. TER only sets how much is withheld in each of the other months. ### Why is December withholding so small, or negative? Because January to November already withheld close to the annual tax, or more than it. Any excess is refunded to the employee by the end of January (PMK 168/2023, Article 21(1)). ### Which category does a married employee with one child use? K/1 falls in category B. A married employee with no dependants (K/0) is category A, and K/3 is the only status in category C. ### What happens when an employee leaves mid-year? The month they leave becomes their final tax period (PMK 168/2023, Article 1). You run the annual calculation in that month instead of December and issue the annual slip. ### Are employer BPJS contributions taxable to the employee? Partly. The employer's JKK, JKM and BPJS Kesehatan contributions are added to gross income (PMK 168/2023, Article 5(3)). The employer's JHT and JP contributions are not. ## Sources 1.
