If you run a foreign-owned company (PT PMA) in Indonesia, the expenses you deduct directly shape how much corporate income tax you pay. While most ordinary business costs are deductible, the difficulty lies in the link between deductions and withholding tax.
In a tax audit, an expense can be disallowed simply because the withholding tax on the payment behind it was never withheld or remitted, even when the expense itself was genuine.
When is an expense tax-deductible in Indonesia?
For an expense to become tax deductible, it needs to to meet two conditions:
1. The expense passes the 3M test
Under Article 6 of the Income Tax Law, your PT PMA can deduct expenses incurred to obtain, collect, and maintain taxable income, a test known as the 3M principle. The test covers salaries, rent, services, materials, and interest, etc as long as they serve the business's income.
2. The withholding tax on the payment was withheld and remitted
For most expense types, the deduction is only recognized if your company withheld, reported, and remitted the applicable withholding tax (WHT) when paying the third party.
For instance, if you pay a consultant without withholding PPh 23, the Directorate General of Taxes (DJP) can disallow the entire consulting expense as a fiscal correction during the audit. Your taxable income then rises by the full amount of the expense, and your corporate income tax bill rises with it.
Since withholding runs monthly on a cash basis, this is an ongoing obligation rather than a year-end one.
Deductible expenses and their withholding tax rates
The table below maps the common deductible expense types to the WHT article that applies and the standard domestic rate:
| Deductible expense | WHT article | Standard rate | Notes |
|---|---|---|---|
| Material and goods purchases | PPh 22 | 0.5% to 2.5%, often exempt | Standard domestic purchases are generally exempt; imports carry PPh 22 at 2.5% with an API import license, 7.5% without |
| Wages, salaries, and bonuses | PPh 21 | Progressive, 5% to 35% | Apply the monthly Average Effective Tax Rate (TER) method; missed PPh 21 breaks the deduction |
| Interest payments | PPh 23 or PPh 4(2) | 15% or 20% | 15% (PPh 23) to local companies and individuals; 20% final (PPh 4(2)) on deposits with domestic banks |
| Rental of equipment and vehicles | PPh 23 | 2% | Applies to movable assets |
| Rental of land and buildings | PPh 4(2) | 10% final | Offices, warehouses, and land |
| Royalty payments | PPh 23 | 15% | Intellectual property usage |
| Business travel | None | Exempt | Fully deductible with proper invoices and receipts |
| Waste treatment services | PPh 23 | 2% | Treated as a technical service |
| Insurance premiums | None | Exempt | Deductible when paid to a domestic insurer |
| Promotion, agency, and sales services | PPh 23 | 2% | Paying an agency triggers the 2% WHT, and a Daftar Nominatif (nominative list) of promotion spending must be filed |
| Promotional prizes and giveaways | PPh 4(2) | 25% final | Cash and lottery-style prizes |
| Administrative and consulting fees | PPh 23 | 2% | Legal, accounting, and consulting services |
| Non-income taxes (land and building tax, stamp duty) | None | Exempt | Payments to the state carry no withholding |
| Depreciation and amortization | None | Exempt | Book calculations, no third party paid |
| Employer pension contributions (OJK-approved funds) | None | Exempt | Deductible without withholding |
| Asset disposal and forex losses | None | Exempt | Accounting losses are not payments |
| Outsourced R&D services | PPh 23 | 2% | Internal R&D carries no WHT; outsourcing to a domestic agency does |
| Scholarships and training | None | Exempt | Directly paid education and training fees |
| Bad debt write-offs | None | Exempt | For legally recognized uncollectible receivables |
| Corporate donations (CSR, disaster relief) | None | Exempt | Deductible within the caps and conditions set by government regulation |
| Benefits-in-kind (natura) | PPh 21 | Progressive | Deductible for the company; taxable to the employee unless a specific exemption applies |
To keep these expenses deductible, there are two things you should do consistently:
- Issue a withholding slip (bukti potong) for every payment that carries WHT. These slips are what the auditor reconciles against your expense ledger.
- Follow the special documentation rules where they apply, such as the Daftar Nominatif for promotion costs. Without that list, the promotion expense is disallowed even when the withholding was handled correctly.
Common withholding situations and how to resolve them
Some payments are harder to withhold on than others. These are the situations we see most often at foreign-owned companies, and how to handle each one correctly.
1. When a vendor refuses to be withheld
Small vendors often want their invoice paid in full and will walk away if you deduct 2% or 10% from it. You cannot simply absorb the tax by paying it out of your own pocket. If you pay the WHT on the vendor's behalf without changing the contract value, that tax payment becomes a non-deductible expense for your company.
The compliant answer is the gross-up method. You increase the invoice value so that the amount the vendor receives after withholding equals their asking price, which makes the tax legally part of the vendor's gross income and keeps your whole expense deductible.
Say a vendor wants exactly IDR 10,000,000 net for a service subject to 2% PPh 23. You write the contract for IDR 10,204,082. You withhold 2% (IDR 204,082), remit it, and pay the vendor their IDR 10,000,000. The full IDR 10,204,082 is deductible, the vendor is whole, and the audit trail is clean.
2. When a vendor has no NPWP
A domestic vendor without a tax card (NPWP) triggers penalty withholding rates: PPh 23 doubles from 2% to 4%, and PPh 21 rates rise by 20%. If that vendor also wants a net amount, the gross-up runs on the penalty rate, so the same IDR 10,000,000 net service costs you IDR 10,416,667 on the contract, with IDR 416,667 withheld at 4%.
The better fix, where the relationship justifies it, is upstream: vendors who invoice you regularly should be encouraged to register for an NPWP, since the penalty rate is costing one of you real money on every invoice.
3. Paying foreign vendors: software, SaaS, and services from abroad
When you pay a foreign vendor, two separate obligations apply at the same time, and software purchases are the most common example. Indonesian practice generally treats B2B software licenses, SaaS subscriptions, and activation codes as royalties, which triggers PPh 26 withholding on the payment.
Global vendors will not accept a withheld invoice, so in practice you gross up the PPh 26 internally and pay it from the grossed-up value to keep the expense deductible. Where a tax treaty applies, the rate can be reduced, provided the vendor supplies its certificate of residence through the DGT form process.
The second obligation is VAT on the imported service (PPN JLN). The statutory VAT rate is 12%, applied through an adjusted base that makes the effective charge 11% for standard services. How you pay it depends on the vendor:
- If the vendor is a registered PMSE collector (the major digital companies, such as Google, AWS, and Zoom, are), they add Indonesian VAT to your invoice and remit it themselves. You pay the invoice total and record their digital invoice in your tax portal; nothing to self-remit.
- If the vendor does not collect (a smaller foreign software house, for instance), you self-assess: create a billing code for PPN JLN in Coretax, pay the effective 11% to the state bank, and report it.
Please keep in mind that the self-paid VAT is not lost money. If your company is VAT-registered (a PKP), the PPN JLN you remit becomes input tax that offsets your monthly output VAT.
Keeping the deductions safe with Emerhub
These rules are easy to follow on a single invoice. The difficulty comes with volume. A typical PT PMA makes dozens of payments every month across different WHT articles, and each one needs the right rate, a withholding slip, a monthly remittance, and in some cases a supporting list.
Missed withholdings usually go unnoticed until a tax audit years later, where they surface as fiscal corrections priced at the full expense plus penalties.
Emerhub's accounting team in Indonesia manages the entire cycle for foreign-owned companies. Our team handles the monthly withholding calculations and filings across PPh 21, 22, 23, 26, and 4(2), the bukti potong issuance, the gross-up handling in vendor contracts, and the PPN JLN self-assessments through Coretax.
If you need support beyond the withholdings, our team also manages the full tax and accounting cycle in Indonesia: bookkeeping, monthly and annual tax filings, and advice on structuring your expenses so the company does not pay more tax than it should.

Frequently asked questions
Is an expense deductible if I did not withhold the tax on it?
In an audit, the DJP can disallow an expense where the required withholding was not made, reclassifying it as non-deductible and raising your taxable income by the full amount. Keeping deductions safe means treating the withholding as part of the payment, not an afterthought.
What is the gross-up method?
A compliant way to pay a vendor their full asking price while still withholding. You raise the contract value so that the net amount after withholding equals the vendor's price; the withheld tax becomes part of the vendor's gross income, and your full grossed-up expense stays deductible.
What is the PPh 23 rate for a vendor without an NPWP?
Double the standard rate: 4% instead of 2% for services and rentals. PPh 21 for individuals without an NPWP runs 20% higher than the standard progressive rates.
Do I have to pay VAT on foreign software subscriptions?
Yes, at an effective 11%. If the vendor is a registered PMSE collector, they charge it on the invoice and remit it. If not, your company self-assesses the VAT through Coretax, and if you are VAT-registered, the amount is creditable as input tax.
What is a Daftar Nominatif?
A nominative list itemizing promotion and entertainment spending (recipient, amount, and details) that must be filed for those expenses to be deductible. Without it, the DJP disallows the promotion costs even when the withholding was handled correctly.
