PT PMA Tax Compliance Checklist 2026: Every Monthly, Quarterly, and Annual Obligation

Why Tax Compliance Matters for PT PMA Companies

Running a PT PMA (Penanaman Modal Asing / Foreign Investment Company) in Indonesia means operating under one of the most detailed tax compliance frameworks in Southeast Asia. The Direktorat Jenderal Pajak (DJP) expects timely filing and payment across multiple tax types, each with its own deadlines, forms, and systems.

Non-compliance is not just about fines. Repeated violations trigger tax audits, which can uncover assessments going back 5 years. For PT PMA companies, clean tax compliance is also critical for KITAS renewals, RPTKA approvals, and maintaining your investment license with BKPM.

This checklist covers every obligation your company faces, mapped to exact calendar deadlines.

Monthly Obligations Overview

Every month, a PT PMA company must handle up to 8 separate tax obligations across payment and reporting. Here is the complete monthly calendar.

Monthly Tax Calendar

Important: If any deadline falls on a weekend or national holiday, the deadline moves to the next working day. However, it is strongly recommended to file 2-3 days before the deadline to account for system congestion and processing delays.

Detailed Monthly Obligations

PPh 21: Employee Income Tax

PPh 21 is the income tax withheld from employee salaries, bonuses, and other employment income. As the employer, your PT PMA is responsible for calculating, withholding, remitting, and reporting this tax.

Who is covered: All employees (Indonesian and foreign), including:

• Permanent employees (karyawan tetap)
• Contract employees (karyawan tidak tetap)
• Foreign workers on KITAS (subject to TER rates or standard progressive rates)
• Directors receiving salary
• Commissioners receiving fees (honorarium)

Tax rates (2026):

Monthly workflow:

1. Calculate gross salary + allowances + benefits for each employee
2. Apply PTKP (non-taxable income threshold) based on marital status
3. Calculate monthly PPh 21 using annualization method or TER (Tarif Efektif Rata-rata)
4. Withhold PPh 21 from employee payslips
5. Create e-Billing code and pay by the 10th
6. Issue bukti potong (withholding certificate) to each employee
7. File SPT Masa PPh 21 via e-Bupot by the 20th

Penalty for late payment: 2% per month interest on unpaid amount Penalty for late filing: IDR 100,000 per SPT Masa

PPh 23: Domestic Withholding Tax

PPh 23 applies when your company makes payments to Indonesian entities or individuals for services, interest, dividends, and royalties.

When to withhold:

Monthly workflow:

1. Identify all payments subject to PPh 23 during the month
2. Calculate withholding amount (2% or 15% of gross payment)
3. Deduct PPh 23 from payment to the recipient
4. Create e-Billing code and pay by the 10th
5. Issue bukti potong to each recipient (they need this for their own tax returns)
6. File SPT Masa PPh 23 via e-Bupot by the 20th

PPh 25: Monthly Corporate Tax Installment

PPh 25 is your company's monthly installment payment toward the annual corporate income tax liability. The amount is calculated based on last year's annual tax return.

Calculation formula: PPh 25 monthly = (Last year's Corporate PPh - Tax credits) / 12

Example: If your 2025 annual corporate tax was IDR 240,000,000 and tax credits (PPh 22, 23, 24) totaled IDR 60,000,000, your monthly PPh 25 for 2026 would be: (IDR 240,000,000 - IDR 60,000,000) / 12 = IDR 15,000,000/month

Payment deadline: 15th of the following month Filing: PPh 25 does not require a separate SPT Masa filing. Payment itself serves as the filing.

Special cases:

• New companies in their first year: PPh 25 may be zero or calculated based on projections
• Companies with losses: PPh 25 is zero, but you must still file nil returns
• Significant revenue change: You can request a PPh 25 adjustment through your tax office

PPN (VAT): Value Added Tax

PPN applies if your company is registered as PKP (Pengusaha Kena Pajak). All companies with annual revenue exceeding IDR 4,800,000,000 must register. Companies below the threshold can register voluntarily.

Current PPN rate: 12% (effective January 2025 for luxury goods; 11% standard rate for most goods/services with effectively 12% applied through calculation adjustments)

Monthly workflow:

1. Issue e-Faktur (electronic tax invoices) for all taxable sales
2. Collect input tax invoices from all taxable purchases
3. Calculate: Output PPN (sales) - Input PPN (purchases) = PPN payable/refundable
4. If PPN payable: Create e-Billing code and pay by end of the following month
5. File SPT Masa PPN via e-Faktur application or Coretax by end of the following month

Example PPN calculation:

Quarterly Obligations

PPh 25 Review and Adjustment

While PPh 25 is paid monthly, a quarterly review is recommended to ensure your installments are aligned with actual revenue. If your company's revenue is significantly higher or lower than last year, you can apply to your tax office (KPP) for a PPh 25 adjustment to avoid underpayment penalties or overpayment cash flow issues.

LKPM (Investment Activity Report)

PT PMA companies registered with BKPM must file quarterly LKPM (Laporan Kegiatan Penanaman Modal) reports. While this is technically an investment report rather than a tax filing, failure to file can affect your company's good standing and trigger scrutiny from both BKPM and DJP.

Annual Obligations

SPT Tahunan Badan (Annual Corporate Tax Return)

The annual corporate tax return is the most significant filing obligation. It consolidates all monthly activities into a comprehensive return that determines your final corporate tax liability.

Deadline: April 30 of the following year (for calendar-year taxpayers)

What it includes:

• Complete financial statements (balance sheet, income statement, cash flow)
• Fiscal reconciliation (commercial vs fiscal profit adjustments)
• Summary of all monthly PPh 21, 23, 25, 26, and 4(2) payments
• Tax credit calculations
• Final corporate tax calculation and any over/underpayment
• Transfer pricing documentation (if applicable)

Corporate income tax rate: 22% on taxable income

Special rate for small businesses: PT PMA companies with gross revenue up to IDR 50,000,000,000 receive a 50% discount on the 22% rate for the portion of taxable income up to IDR 4,800,000,000.

Late filing penalty: IDR 1,000,000

Annual PPh 21 Reconciliation

At year-end, you must reconcile the monthly PPh 21 calculations against each employee's actual annual income. This reconciliation (often called the PPh 21 equalization) may result in additional tax payable or overpayment.

Deadline: January SPT Masa PPh 21 filing (due February 20)

Process:

1. Calculate each employee's actual annual taxable income
2. Apply annual progressive tax rates
3. Compare with total monthly PPh 21 withheld during the year
4. If underpaid: withhold the difference from January salary
5. If overpaid: credit the difference against January PPh 21

SPT Tahunan PPh 21 (Annual Employee Tax Return Compilation)

While individual employees file their own SPT Tahunan (Form 1770/1770S/1770SS), the company must provide each employee with a Form 1721-A1 (bukti potong annual) summarizing their annual income and tax withheld. This must be issued by January 31 of the following year.

Monthly Compliance Workflow

Week 1 (1st-7th)

• Compile previous month's payroll data
• Calculate PPh 21 for all employees
• Review all invoices received for PPh 23 withholding obligations

End of Month

• Issue all e-Faktur output invoices for the month's sales
• File SPT Masa PPN via e-Faktur/Coretax by end of the following month
• Archive all supporting documents (invoices, bukti potong, payment receipts)

Transitioning to Coretax

As of 2026, DJP is progressively migrating all tax administration to the Coretax system, replacing DJP Online, e-Filing, e-Bupot, and e-Billing with a single integrated platform. During the transition:

• Both systems may be operational simultaneously
• Some filing types may only be available on one platform
• System outages during transition periods are common
• Filing deadlines remain the same regardless of system issues (unless DJP issues official extensions)

Recommendation: Maintain access to both DJP Online and Coretax. If one system is down near a deadline, try the other. Document any system errors with screenshots as evidence for potential penalty appeals.
