An overpaid-tax position is common, especially for exporters, taxpayers transacting with VAT collectors, or taxpayers carrying large tax credits. When the tax already paid or withheld exceeds the tax actually due, the state must return the excess. The Tax Overpayment Assessment (Surat Ketetapan Pajak Lebih Bayar, or SKPLB) is the document that forms the basis for that refund.
What is an SKPLB?
An SKPLB is a tax assessment that fixes the amount of overpaid tax because the tax credit exceeds the tax due, or because tax was paid that should not have been due (Article 1 number 19 and Article 17 of the KUP Law). Put simply, the SKPLB is an official acknowledgment by the Directorate General of Taxes (DGT) that the taxpayer has overpaid by a specific amount.
The SKPLB differs from the Tax Underpayment Assessment (SKPKB), which arises when the tax due exceeds the tax credit. It also differs from the Preliminary Refund Decision (SKPPKP), which is issued through a research mechanism rather than a full audit.
Legal basis
Issuance of an SKPLB is governed by the Law on General Provisions and Tax Procedures (KUP Law). The key provisions are:
- After conducting an audit, the DGT may issue an SKPLB where the tax credit or tax paid exceeds the tax due (Article 17 paragraph (1) of the KUP Law).
- The DGT may issue an SKPLB on a request to refund tax that should not have been due (Article 17 paragraph (2) of the KUP Law).
- On a refund request, the DGT must issue a tax assessment within 12 months at the latest from when the complete request is received (Article 17B paragraph (1) of the KUP Law). If the DGT does not decide within that period, the request is deemed granted and the SKPLB must be issued within one month thereafter (Article 17B paragraph (2) of the KUP Law).
- The refund is paid within one month at the latest from when the refund request is received in connection with the SKPLB (Article 11 paragraph (2) of the KUP Law).
How an SKPLB is issued
An SKPLB usually starts from a return reporting an overpayment and including a refund request. On that request, the DGT runs an audit to test whether the overpayment is correct.
The audit covers testing the correctness of the tax calculation, validating withholding and collection slips, matching payments, and validating tax invoices and other supporting documents. Once the audit is complete and the overpayment is proven, the DGT issues an SKPLB for the amount of excess it recognizes.
Note that the SKPLB route differs from a preliminary refund. Under a preliminary refund, certain taxpayers obtain a faster refund through administrative research without waiting for a full audit. However, a preliminary refund can still be audited later, and if a shortfall is found, the DGT may issue an SKPKB together with penalties.
Timelines and interest compensation
Two timelines matter. First, the time to decide the request: the DGT must decide within 12 months at the latest from when the complete request is received (Article 17B paragraph (1) of the KUP Law). Second, the time to pay: once the SKPLB is issued, the excess must be refunded within one month at the latest from when the refund request is received (Article 11 paragraph (2) of the KUP Law).
If the DGT issues the SKPLB late, beyond the prescribed period, the taxpayer is entitled to interest compensation under Article 17B of the KUP Law. The amount follows the monthly interest rate set by the Minister of Finance.
Worked example
PT Sinar Ekspor is an exporter with many VAT-facilitated transactions. On its annual and periodic VAT returns, the company records tax credits of IDR 1,500,000,000 while the tax due is only IDR 900,000,000. That leaves an overpayment of IDR 600,000,000.
The company includes a refund request in its return. The DGT runs an audit and, after testing, recognizes an overpayment of IDR 580,000,000 (a IDR 20,000,000 correction is made for an invalid invoice). The DGT issues an SKPLB for IDR 580,000,000. Under Article 11 paragraph (2) of the KUP Law, that amount is refunded within one month at the latest from when the refund request is received.
