Foreign companies operating through a PT PMA in Indonesia can legally reduce the default 20% PPh Pasal 26 withholding rate by applying an applicable tax treaty in Coretax, provided they secure a valid SKD and follow proper e-Bupot procedures under PER-25/PJ/2018 and PER-11/PJ/2025. Since January 2025, this process is fully integrated into Coretax for electronic withholding slips and SPT Masa PPh 21/26 reporting under the supervision of Direktorat Jenderal Pajak (DJP).
If you are a foreign business owner or representative in Indonesia, this mechanism directly impacts your cash flow, tax efficiency, and compliance exposure.

Understanding the Default 20% Withholding vs Treaty Rates
By default, payments to non-residents are subject to 20% withholding on gross income under PPh 26. This applies to royalties, interest, services, dividends, and other cross-border payments.
However, if Indonesia has a Double Tax Treaty with the recipient’s country, the rate may be reduced to 10% or 15%, depending on the income type and treaty terms.
The key requirement is clear: without a valid SKD, Coretax will automatically apply the full 20% rate to avoid penalties.
Step 1: Obtain SKD (Certificate of Domicile)
Before claiming treaty benefits, the foreign party must obtain an SKD WPLN through the e-SKD menu on pajak.go.id.
The SKD confirms:
- Country of tax residence
- Treaty eligibility
- Identity details matching the foreign TIN
You must provide this SKD receipt to the Indonesian withholding agent, typically your PT PMA entity.
If the SKD is missing or invalid, the system defaults to 20%.
Step 2: Create e-Bupot BP 26 in Coretax
Inside Coretax, navigate to:
e-Bupot → BP 26 → Create eBupot BP26
Then:
- Select the “Fasilitas” option for SKD/tax treaty
- Input foreign TIN, name, address, and country code
- Enter gross income and select the correct tax object code
- Upload supporting documents such as invoice and NITKU reference
- Input SKD receipt number under “SKD WPLN Terdaftar”
- Save as draft to validate
- Digitally sign to generate QR-verified slip
The system will automatically apply the reduced treaty rate if all fields align with PER-11/PJ/2025 country codes.

Step 3: Payment and Monthly Reporting
Deadlines are strict:
- Payment via billing code: no later than the 10th of the following month
- SPT Masa PPh 21/26 submission: no later than the 20th
Coretax auto-populates SPT Masa from e-Bupot entries. Even if no treaty is used, reporting remains mandatory.
Always retain SKD and documentation for audit trail purposes.
Common Coretax Mistakes That Trigger 20% Default
Many PT PMA entities face avoidable issues:
Data Entry Errors
- Incorrect country codes
- TIN mismatch
- Missing passport or date of birth
- Wrong tax object code
- Incorrect gross income input
These errors cause validation failure or automatic 20% recalculation.
Menu Selection Errors
- Using BP 26 instead of BPNR
- Selecting “Normal” instead of “Pembetulan” for corrections
- Wrong tax period format
These mistakes can create uneditable slips or kompensasi overpayment issues.

Prevention and Correction Strategy
We always recommend:
- Save as draft first
- Validate country codes against PER-11/PJ/2025
- Match invoice numbers and NITKU exactly
- Re-submit using Pembetulan status for corrections
- Create offsetting BP 26 in next period if kompensasi error occurs
Proper validation before digital signing prevents costly rework.
Why This Matters for Foreign Business Owners
Tax treaty optimization is not just about compliance. It is about preserving margins.
A 5–10% reduction on cross-border payments significantly impacts profitability. But improper execution creates audit flags and unnecessary overpayments.
This is where structured compliance and documentation discipline matter most.

Frequently Asked Questions
What happens if SKD is not submitted in Coretax?
Coretax automatically applies the default 20% PPh 26 rate to avoid non-compliance penalties.
Can treaty benefits be applied after payment?
Corrections may be possible through Pembetulan status, but prevention before payment is strongly recommended.
What is the difference between BP 26 and BPNR in Coretax?
BP 26 is typically used for certain foreign personal service payments, while BPNR applies to other non-resident income categories. Selecting the wrong menu causes validation errors.
When are PPh 26 payment and reporting deadlines?
Payment is due by the 10th of the following month. SPT Masa PPh 21/26 must be filed by the 20th.
