2026 Tax Calendar
Indonesia tax deadlines 2026 for Bali businesses and finance teams
A practical 2026 guide to recurring PPh and PPN deadlines plus annual SPT filing dates. Built for Bali SMEs, PT PMA companies, and operators who need a cleaner tax calendar.
What this 2026 deadline guide actually covers
When owners search for Indonesia tax deadlines 2026, they are usually trying to manage two things at once: the recurring monthly filing cycle during 2026 and the annual filing season in March and April 2026 for tax year 2025.
For business teams using a calendar-year tax period, the main annual dates are straightforward. Individual annual returns are generally due within three months after year-end, while corporate annual returns are due within four months after year-end. That means March 31, 2026 for individuals and April 30, 2026 for companies, unless a specific administrative change is announced.
The recurring monthly cycle is equally important because late monthly work creates a backlog that makes annual filing harder. If your bookkeeping, payments, and reporting are not aligned by month, annual SPT season becomes a clean-up project instead of a filing project.
Monthly tax deadlines for 2026
The table below is the recurring pattern most Bali SMEs and PT PMA finance teams work from. It gives you a stable monthly framework for planning, even though you should still check official announcements for holiday shifts and system updates.
| Tax type | Payment deadline | Filing deadline | Notes |
|---|---|---|---|
| PPh 21 | 10th of the following month | 20th of the following month | Employee withholding tax. |
| PPh 23 / 26 | 10th of the following month | 20th of the following month | Common for service fees, royalties, and cross-border cases. |
| PPh 25 | 15th of the following month | 20th of the following month | Monthly corporate income-tax installment. |
| PPh Final Article 4(2) | 15th of the following month | 20th of the following month | Applies when your regime or transaction type falls under final tax rules. |
| PPN / VAT | End of the following month | End of the following month | Payment is made before or together with the monthly VAT return workflow. |
If your business relies on monthly admin staff or part-time finance support, this is the section to turn into calendar reminders. Do not wait until the filing week to request missing invoices, payroll data, or withholding evidence. The better pattern is to prepare records in the first week after month-end, then move into payment and filing.
Annual filing deadlines in 2026
The annual-return season is where many businesses slip because they assume the monthly work was enough. In reality, annual SPT filing usually requires cleaner reconciliations, complete financial statements, and a final review of taxes already paid through the year.
| Obligation | Due date | Applies to |
|---|---|---|
| Annual individual income-tax return | March 31, 2026 | Calendar-year individual taxpayers |
| Annual corporate income-tax return | April 30, 2026 | Calendar-year corporate taxpayers |
| Corporate annual-return extension notice | Before April 30, 2026 | Companies that need up to 2 extra months |
DJP also announced that annual-return reporting for 2026 begins through Coretax DJP from January 1, 2026. That makes early access setup and role permissions part of deadline planning, not just a technical afterthought.
Penalties and risk points to watch
Filing dates matter because Indonesian tax administration is structured around automatic consequences. The easiest way to reduce penalty risk is not to memorize every sanction, but to keep each monthly filing cycle clean enough that deadlines stay routine.
- Late filing of monthly SPT Masa other than VAT generally triggers an administrative penalty of Rp 100,000 per return.
- Late filing of monthly SPT Masa PPN generally triggers an administrative penalty of Rp 500,000 per return.
- Late filing of annual SPT Orang Pribadi generally triggers Rp 100,000.
- Late filing of annual SPT Badan generally triggers Rp 1,000,000.
- Late-payment interest is not a fixed number forever. DJP publishes administrative interest tariffs periodically, so check the current official rate for the relevant period.
If your business is already late or unsure about prior filings, handle the review before peak filing weeks. A short remediation review in January or February is far cheaper than scrambling after a notice or discovering mismatched balances during annual filing.
Should you prepare early for 2026 annual filing?
Yes. The strongest way to handle Indonesia tax deadlines 2026 is to treat annual filing as a preparation project, not a one-week event. That means closing books earlier, reconciling monthly payments, checking Coretax access, and deciding early whether a corporate extension might be needed.
