About

Same salary, different deduction? Since 2024, Indonesian permanent employees have PPh 21 withheld at a monthly effective rate (TER): one percentage of gross pay, set by the pay band and PTKP status. A month with a bonus or THR jumps to a higher band, and December is recalculated on the Article 17 progressive schedule. This app shows all of it, with the regulation's own numbers. CALCULATE Enter gross monthly pay and PTKP status (TK/0 to K/3) and see this month's deduction, the rate and the TER category. RATE BANDS See the band your pay landed in, the bands either side, and how many rupiah until the rate changes. MONTHS Record the year month by month. Add THR or a bonus and see the deduction recomputed beside the previous month. DECEMBER Project the December recalculation from the months recorded: annual income, occupational expense, PTKP, taxable income, the year's PPh 21, and the difference against January–November — what December deducts, or what the employer must refund. NUMBERS FROM THE REGULATION TER tables A, B and C from PP 58/2023. PTKP from PMK 101/2016. Article 17 rates from Law 7/2021. Deductions, rounding and the December rule from PMK 168/2023, reproducing the official worked examples. FULLY OFFLINE No account, no sign-in, no ads, no analytics, no internet connection. Your months stay on your device. For permanent employees on monthly pay. Not yet for non-permanent employees, expatriates, severance, or K/I status. Figures are estimates, not tax advice.

What's New in Potongan

1.0.3

September 10, 2026

Your PTKP status is now asked, not assumed. The app used to default to TK/0 until you changed it yourself. So if you are married or have dependants, the figure could be well off, with nothing on screen to say so. It now asks two questions, once, the first time you open it, and calculates from your answers. Also: the figures on the Desember tab are no longer faded above the tab bar, and codes like TK/0 no longer break across lines.
