For medium and large businesses, including PT PMA companies subject to quarterly reporting, Regulation No. 5 of 2025 sets the following LKPM deadlines:
- Quarter I — January to March: submit by 15 April of the same year;
- Quarter II — April to June: submit by 15 July of the same year;
- Quarter III — July to September: submit by 15 October of the same year;
- Quarter IV — October to December: submit by 15 January of the following year.
The standard deadline is therefore the 15th of the month following the quarter, rather than the 10th stated in some older guidance.
For the third quarter of 2026, OSS has announced a
reporting period of 1–15 October 2026. Companies should prepare their July–September records and submit the report by 15 October 2026.
For the fourth quarter of 2026, the standard deadline is 15 January 2027.
Avoid leaving submission until the final day. Allow time to reconcile figures, resolve access problems and respond to any requests for correction. After submitting, check the report’s status in OSS and retain the submission evidence.
If the authorities announce an adjustment or extension for a particular reporting period, check its scope and conditions before relying on it. A previous extension should not be assumed to apply to the next quarter.
