In the employment ecosystem, not all workers have permanent status. Many work under the Non-Permanent Employee (Pegawai Tidak Tetap/PTT) or Casual Worker scheme, where their income is paid based on days worked, units produced, or the completion of specific jobs. Since January 1, 2024, the government, through Government Regulation No. 58 of 2023 and Minister of Finance Regulation No. 168 of 2023, has completely overhauled the tax calculation mechanism for this category to simplify administration.
The most fundamental change is the removal of the complex monthly cumulative calculation mechanism. Now, tax calculation for non-permanent employees depends entirely on two main factors: the payment method (whether paid daily/weekly/per unit/piece-rate or paid monthly) and the daily gross income amount.
If a non-permanent employee receives wages on a daily, weekly, unit, or piece-rate basis—and is not paid monthly—the calculation base refers to the daily gross income. There are three applicable tariff layers:
For weekly, unit, or piece-rate wages, the income must first be converted into an average daily income (total income divided by days worked) to determine which rate applies.
If a non-permanent employee receives wages paid in a lump sum on a monthly basis, the calculation is treated the same as permanent employees, which is using the Monthly Average Effective Rate (TER).
The employer simply looks at the TER table (Category A, B, or C) according to the employee's PTKP status, then multiplies the percentage by the total gross income for that month.
Mr. L works assembling photo frames for 10 days on a piece-rate basis worth Rp4,500,000.
Mr. K works for 20 days with a daily wage of Rp500,000.
Mr. M works repairing electronics with a unit rate of Rp300,000 per unit. In one day, he finishes 10 units, so his income is Rp3,000,000 a day.
Mr. N is a tea picker (non-permanent employee) paid based on harvest yield, but paid once a month. In January, his total income was Rp4,000,000. His status is Single (TK/0).
This latest regulation provides certainty and simplicity. For casual workers with daily income under Rp450,000, the tax-free guarantee is now firmer without the need to calculate monthly accumulations. For employers, the use of the 0.5% effective rate or monthly TER significantly speeds up the payroll administration process.
