Filing an annual corporate tax return (SPT Tahunan Badan) in Indonesia can result in an unexpected tax obligation known as PPh 29 underpayment. This happens when a company’s actual taxable income exceeds the income used to calculate its monthly PPh 25 installments. The remaining tax gap must be paid before April 30 to avoid interest penalties.
For foreign-invested companies (PT PMA), this risk can be higher. Revenue growth, new business activities, product changes, or currency fluctuations can increase taxable income beyond the previous year’s estimate. Without regular tax monitoring, companies may face large PPh 29 payments at year-end.
To avoid unexpected year-end tax payments, companies need to understand how PPh 29 is calculated, when it must be paid, and what steps to take to monitor the risk before filing.
Key Takeaways
- PPh 29 is the remaining corporate income tax payable when a company’s annual tax due is higher than its prepaid tax credits and PPh 25 installments.
- Corporate PPh 29 underpayment must be paid before submitting the annual corporate tax return, with April 30 as the usual filing deadline for calendar-year taxpayers.
- Indonesia’s standard corporate income tax rate is 22% of net taxable income, while eligible SMEs may use the 0.5% final tax regime.
- PPh 29 risk can increase when revenue grows, new business activities are added, tax credits are lower than expected, or fiscal corrections increase taxable income.
- Companies should review deductible expenses, tax credits, PPh 25 installments, and transfer pricing adjustments before filing to avoid underpayment and penalties.

What is PPh 29?
PPh 29 is the remaining income tax that must be paid when a company’s annual tax payable is higher than the tax already paid during the year.
These prepaid taxes may include:
- PPh 22 from import or certain business transactions
- PPh 23 from dividends, royalties, interest, or service payments
- PPh 25 monthly corporate income tax installments
In simple terms, PPh 29 is an underpayment. It is not a penalty, but the unpaid balance of the company’s income tax obligation for the fiscal year.
Why corporate PPh 29 happens
Monthly PPh 25 installments are usually based on the previous year’s annual tax return and divided into 12 payments. Because this calculation looks backward, the installments may no longer match the company’s current business performance.
PPh 29 underpayment can become larger when:
- Revenue or profit increases beyond the previous year’s estimate.
- New business activities are added, such as new contracts, products, or services.
- Tax credits are lower than expected, including PPh 22 or PPh 23.
- Non-deductible expenses are found during the fiscal closing, increasing taxable income.
- Transfer pricing adjustments are made, especially for related party transactions.
Current corporate income tax rates in Indonesia
Under UU HPP No. 7/2021, Indonesia’s standard corporate income tax rate is 22% of net taxable income.
| Entity Type/Revenue | Applicable Tax Rate |
| Gross revenue above IDR 50 billion | 22% of net taxable income |
| Gross revenue between IDR 4.8 billion and IDR 50 billion | Blended rate: 11% on the eligible portion and 22% on the remaining taxable income |
| Gross revenue up to IDR 4.8 billion | 0.5% final tax on gross revenue, subject to eligibility under PP 55/2022 |
| Publicly listed companies meeting PMK 40/2023 criteria | 19%, or 3% lower than the standard corporate tax rate |
Note for PT PMA: Foreign-invested companies generally follow the same 22% standard corporate tax rate. However, dividend payments to foreign shareholders, related-party transactions, and tax treaty benefits can affect the company’s effective tax exposure. These areas often require further tax review before filing or profit distribution.

How to calculate corporate PPh 29
For companies with gross revenue above IDR 50 billion, PPh 29 is calculated by comparing the annual tax payable with the tax credits paid during the year, helping companies clearly understand their potential underpayment.
Step 1: Calculate gross income
Add all taxable income, including sales, service revenue, and other business income.
Step 2: Subtract deductible expenses
Deduct business expenses used to earn, collect, and maintain income, often referred to as Biaya 3M. Non-tax-deductible expenses must be added back through a fiscal correction.
Step 3: Determine net taxable income
After deductible expenses and fiscal corrections, the company arrives at its net taxable income (PKP).
Step 4: Apply the corporate tax rate
Calculate annual corporate tax payable using the standard 22% rate.
Tax payable = 22% × net taxable income
Step 5: Subtract prepaid tax credits
Deduct tax credits already paid during the year, such as PPh 22, PPh 23, and PPh 25 installments.
PPh 29 = tax payable − prepaid tax credits
When the final amount is positive, the company has a PPh 29 underpayment that must be paid before submitting the annual corporate tax return.
Deductible vs non-deductible expenses under UU HPP
Correctly classifying expenses is important because it affects fiscal corrections and the final PPh 29 calculations.
Deductible expenses
These are expenses that can generally reduce taxable income if they are related to business activities:
- Employee benefits that are properly structured and documented
- Meals and beverages are provided for all employees
- Transportation or operational support related to work
- Health facilities or medical support for employees
- Safety equipment and work uniforms
- Other expenses used to obtain, collect, and maintain taxable income
Non-deductible expenses
These are expenses that generally cannot reduce taxable income and must be added back through fiscal correction:
- Personal expenses not related to business activities
- Excessive or unsupported entertainment expenses
- Expenses without proper invoices or documentation
- Penalties and sanctions that are not tax-deductible
- Benefits or facilities that are not properly classified under tax rules
For PPh 29, misclassification can create two risks: overpayment, which affects cash flow, or underpayment, which results in additional tax and interest.
How to pay corporate PPh 29
Corporate PPh 29 underpayment is paid through DJP Online e-Billing before the annual corporate tax return is submitted.
In general, companies need to:
- Log in to DJP Online using the company’s NPWP account.
- Create a billing code for the PPh 29 payment.
- Enter the correct tax period and underpayment amount.
- Complete the payment through an available banking channel.
- Keep the payment receipt, or Bukti Penerimaan Negara (BPN), for annual tax filing records.
While the payment process may seem straightforward, errors in calculation, tax classification, or filing timing can create unnecessary delays.

Key deadlines and penalties
Corporate PPh 29 must be paid before the annual corporate tax return is submitted. For companies using the calendar year, the filing deadline is generally April 30.
| Action | Deadline |
| Pay PPh 29 underpayment | Before submitting the annual corporate tax return |
| File SPT Tahunan Badan | No later than April 30 for calendar-year taxpayers |
| Request filing extension | Before the filing deadline, make an estimated tax payment if applicable |
Late payment may result in monthly interest on the unpaid tax amount at the rate set by the Minister of Finance. If the annual corporate tax return is not filed, companies may also face a fixed administrative penalty of IDR 1,000,000, in addition to any interest on any underpayment.
To avoid penalties, companies should calculate and settle PPh 29 before filing the annual corporate tax return.
