Guide to Indonesian PPh 21 Tax Brackets Under the UU HPP
In Indonesia, personal income tax is primarily governed by the PPh 21 (Pajak Penghasilan Pasal 21) framework. This covers withholding taxes deducted by employers from employee salaries, wages, honorariums, and other work-related payments. The system underwent a landmark transformation with the passage of Law No. 7 of 2021 on the Harmonization of Tax Regulations (Undang-Undang Harmonisasi Peraturan Perpajakan, or UU HPP). The UU HPP revised the progressive tax brackets to support low-to-middle income earners while introducing higher tax rates for high-net-worth individuals.
For Year of Assessment (YA) 2026, the UU HPP progressive tax brackets continue to apply. These brackets determine the final annual tax liabilities for resident individual taxpayers. Understanding these brackets is vital for both payroll compliance officers and employees looking to audit their tax withholding.
The YA 2026 Progressive Tax Brackets
The UU HPP restructured the tax brackets by increasing the threshold of the lowest bracket and adding a new top-tier bracket for ultra-high earners. The progressive tax brackets for resident individual taxpayers under the UU HPP are as follows:
| Bracket | Taxable Income Range | Tax Rate |
|---|---|---|
| 1 | Up to IDR 60,000,000 | 5% |
| 2 | Above IDR 60,000,000 up to IDR 250,000,000 | 15% |
| 3 | Above IDR 250,000,000 up to IDR 500,000,000 | 25% |
| 4 | Above IDR 500,000,000 up to IDR 5,000,000,000 | 30% |
| 5 | Above IDR 5,000,000,000 | 35% |
Key Changes from the Previous Regime
Compared to the old Income Tax Law (UU PPh), the UU HPP introduced two major changes:
- Bracket 1 Expansion: The 5% rate limit was raised from IDR 50,000,000 to IDR 60,000,000. This provides tax relief to lower-income earners by keeping a larger portion of their income in the lowest tax tier.
- New 35% Tier: A new top bracket of 35% was introduced for taxable income exceeding IDR 5,000,000,000. Previously, the maximum tax rate was 30% on all income above IDR 500,000,000.
Calculating Taxable Income (PKP)
The progressive tax rates are applied to Taxable Income (Penghasilan Kena Pajak, or PKP), not gross salary. To calculate PKP, several statutory deductions must be subtracted from Gross Income:
- Occupation Expense (Biaya Jabatan): Employees are entitled to a standard deduction of 5% of gross salary, capped at IDR 500,000 per month (IDR 6,000,000 per year).
2. Social Security Deductions: Employee contributions to BPJS Ketenagakerjaan (specifically the Old Age Protection, JHT, of 2% and the Pension Protection, JP, of 1%) are tax-deductible.
3. Non-Taxable Income (PTKP): The statutory personal exemption threshold. For a single individual without dependents (TK/0), the baseline PTKP is IDR 54,000,000 per year.
Formula:
PKP = Gross Income - Biaya Jabatan - BPJS Deductions - PTKP
The Average Effective Tax Rate (TER) System
To simplify monthly withholding calculations, the Indonesian government introduced the Average Effective Tax Rate (Tarif Efektif Rata-rata, or TER) under Government Regulation No. 58 of 2023 (PP 58/2023) and PMK 168/2023, effective since January 1, 2024.
Under this system, monthly tax withholding is calculated by multiplying gross monthly income by a specific TER percentage, which is determined by the taxpayer's PTKP category (Category A, B, or C). This replaces the old, complex monthly progressive calculations. However, in the final tax month of the year (December), the employer must perform a recalculation using the annual progressive Article 17 UU HPP tax brackets. The tax withheld in December is the annual progressive tax due minus the sum of monthly taxes paid under the TER system from January to November.
Example Calculation: Mid-Level Professional
Let's calculate the annual PPh 21 tax liability for a single employee (TK/0 status) with a monthly gross salary of IDR 15,000,000 (annual gross salary of IDR 180,000,000):
- Annual Gross Income: IDR 180,000,000
- Biaya Jabatan (5%, capped): IDR 6,000,000
- Employee JHT Contribution (2%): IDR 3,600,000
- Employee JP Contribution (1%, capped at IDR 10,977,600 salary ceiling): 1% * (IDR 10,977,600 * 12) = IDR 1,317,312
- Net Annual Income: IDR 180,000,000 - IDR 6,000,000 - IDR 3,600,000 - IDR 1,317,312 = IDR 169,082,688
- PTKP (TK/0): IDR 54,000,000
- Taxable Income (PKP): IDR 169,082,688 - IDR 54,000,000 = IDR 115,082,688 (rounded to IDR 115,082,000 for calculation)
Applying UU HPP Progressive Brackets:
- First Bracket (5% on first IDR 60,000,000): 5% * IDR 60,000,000 = IDR 3,000,000
- Second Bracket (15% on remaining IDR 55,082,000): 15% * IDR 55,082,000 = IDR 8,262,300
- Total Annual PPh 21 Tax Due: IDR 3,000,000 + IDR 8,262,300 = IDR 11,262,300
