After obtaining the amount of net income in one year, you must calculate the amount of Non-Taxable Income.

The goal is to find out the amount of Taxable Income (PKP). Taxpayers whose income is equal to or below the PTKP are automatically not subject to PPh.

PTKP tax rate  itself has been determined. PTKP rates that are important for you to understand include:

  • Rp. 54. 000,000 in the name of an individual or individual taxpayer without dependents
  • Rp. 4,500,000, additional tax payers who are married

Income Tax Rates

According to the method for calculating personal income tax above, after finding the PKP value, you just need to multiply it by the PPh percentage.

The percentage or rate of income tax is adjusted according to Law no. 46 of 2008, namely:

  • A tax rate of 5% will be imposed on net income of less than 50 million
  • A tax rate of 15% is imposed on net income whose value ranges from 50-250 million
  • A tax rate of 25% is imposed on net income of 250-500 million
  • Meanwhile, for income above 500 million, it will be multiplied by an income tax rate of 30%.

To facilitate the practice of calculating income tax, we make a calculation simulation as follows.

Wahyu is a private employee with one child. He has a gross income of 150 million rupiah each year. Wahyu also pays pension contributions of 1 million each month.

Then the way to calculate the income tax that Wahyu must pay each year is:

  1. Calculate net income (gross income-contributions), 150 million – (12x 1 million)= 138 million
  2. Calculate PTKP = Wahyu + wife + children = 54 million + 4,500,000 + 4,500,000 = 63 million
  3. Calculate Taxable Income (PKP) = Net income – PTKP = 138 million – 63 million = 75 million
  4. Calculate the income tax that Wahyu has to pay in a year. Because his salary is 75 million, the PKP is multiplied by the PPh rate of 15%. Then 75 million x 15% = 11,250,000

So, in one year, the amount of income tax that Wahyu has to pay is 11,250,000 rupiah.
