An employee's net income is Rp6,000,000 .00. The employees are not married and have no dependents.

C. Gross Up Method PPh 21 Calculation

Calculate PPh 21 using Gross Up Method is where the company gives Tax Allowance that is the same amount with the PPh 21. This method is more complicated than other methods. How to calculate?

First, calculate the Tax Allowance:
    The rates of Taxable Income (PKP) Tax Allowance is:

  • PKP 0 - Rp57,000.000 ,00 = PKP x 5/95
  • PKP Rp57,000.000 ,00 - RP218,500,000 = ((PKP - Rp57,000.000 ,00) x 15/85) + Rp3,000,000 .00
  • PKP Rp218,500.000 ,00 - RP406,000,000 = ((PKP - Rp218,500.000 ,00) x 25/75) + Rp31,500,000 .00
  • PKP Rp406,000,000 - Rp3,298,100,000 .00= ((PKP - Rp406,000.000 ,00) x 30/70) + Rp94,000,000 .00
  • PKP > RpRp3,298,100,000 .00 = ((PKP - RpRp3,298,100,000 .00) x 35/65) + Rp1,701,900,000 .00

    For Example, the Net Salarry is Rp10,000,000 and Annual Net Salary is Rp120,000,000 .00:

  • Taxable Income (PKP) = Annual Nett Salary - Non-Taxable Income (PTKP) TK/0
    Taxable Income (PKP) = Rp120,000,000 .00 - Rp54,000,000 .00
    Taxable Income (PKP) = Rp66,000,000 .00
  • Tax Allowance (PPh 21) Annual Progresif Rates:
    ((Rp66,000,000 .00 - Rp57,000.000 ,00) x 15/85) + Rp3,000,000 .00 = Rp4,588,235 .29
  • Monthly Tax Allowance (PPh 21):
    Rp4,588,235 .29 : 12 = Rp382,352 .94 


Second, calculate the Employee PPh 21:

  • Monthly Net Salary = Rp10,000,000 + Tax Allowance
    Monthly Net Salary = Rp10,382,352 .94
    Annual Net Salary = Rp124,588,235 .29
  • Taxable Income (PKP) = Annual Nett Salary - Non-Taxable Income (PTKP) TK/0
    Taxable Income (PKP) = Rp124,588,235 .29 - Rp54,000,000 .00
    Taxable Income (PKP) = Rp70,588,235 .29
  • Employee Income Tax (PPh 21) Annual Progresif Rates
    5% x Rp60,000,000 = Rp 3,000,000 .00
    15% x Rp 10,588,235 .29 = Rp 1,588,235.29
    PPh 21 Annual = Rp 4,588,235 .29
  • Employee Income Tax (PPh 21) that should paid by Employee:
    Rp4,588,235 .29 : 12 = Rp382,353 .94
