Understanding tax penalties
Late filing penalty
A fixed administrative penalty by SPT type: monthly VAT return Rp500,000; other monthly Rp100,000; annual individual Rp100,000; annual corporate Rp1,000,000.
Late/underpayment interest
Computed monthly: monthly interest rate × tax principal × number of months. A partial month is counted as a full month per the rules.
The interest rate changes monthly
The penalty interest rate is set by the Minister of Finance EVERY month and varies. So this calculator asks you to enter the current month's rate rather than guessing it.
FAQ
Frequently asked questions
How much is the late SPT filing penalty?
It depends on the SPT type: monthly VAT Rp500,000; other monthly Rp100,000; annual individual Rp100,000; annual corporate Rp1,000,000. Pick the SPT type in the calculator.
How is late-payment interest computed?
Interest = monthly interest rate × tax principal × months late. Since the rate changes monthly, you enter it yourself. The calculator sums interest with the principal.
Why isn't the interest rate provided automatically?
Because the penalty interest rate is set monthly by the Minister of Finance and varies. A fixed number would risk misleading you. Check the current month's rate in the latest official announcement.
Where do I find the latest penalty interest rate?
In the monthly Minister of Finance decree on penalty interest rates, or the official tax authority site. Enter the relevant month's figure into the calculator.
Are there penalties besides fines and interest?
There can be others depending on the case (e.g. surcharges in certain conditions). This calculator focuses on filing penalties and late/underpayment interest as an estimate. Verify with the tax authority.
