Accurate, timely, and compliant Indonesian Corporate tax reporting — without the stress.
Every Indonesian legal entity must file an Annual Indonesian Corporate Tax Return (SPT 1771) — even if:
- The company was dormant during the year; or
- Founders/directors live abroad
- Law No. 7/2021 (Harmonization of Tax Regulations – HPP Law)
- PER-30/PJ/2017 (Corporate SPT forms & procedures) and related DGT rules
DGT is rolling out the Coretax platform for corporate taxpayers in 2025, replacing DJP
Online for most corporate filings. Companies should ensure access and credentials are active
before the deadline.
What you’ll need for Corporate Tax filing
- NPWP (company tax ID) & EFIN (activated)
- Financial statements for the year (audited where required)
- Monthly tax data: PPh 21/23/26 e-Bupot, PPh 25, PPN (if PKP)
- Supporting records: trial balance/GL, bank statements, fixed-asset register
- SPT 1771 completed and submitted via Coretax
April 30 or 4 months after the fiscal year end (calendar-year taxpayers). Extensions require DGT approval.
Late filing fine: IDR 1,000,000
- Late payment/underpayment: administrative interest accrues (rate set by MOF;
calculated per month/fraction) until paid. - Criminal sanctions may apply for proven tax crimes (UU KUP).
