Corporate Accounting & Taxation: Fundamentals, PSAK, and Tax Compliance
Corporate accounting and taxation cover PSAK-compliant financial reporting alongside tax obligations such as PPh 21, PPh 23, final income tax, and VAT. Since PMK 168/2023, monthly PPh 21 withholding uses the Average Effective Rate (TER) method. Sound compliance requires integrating accounting records with electronic tax reporting (e-Invoice, e-Bupot).

Overview
Every business entity in Indonesia must prepare financial statements that fairly reflect its financial position and performance, while also meeting the tax obligations tied to its business transactions. Accounting and taxation are closely linked: accounting profit is the starting point for the fiscal reconciliation used to compute taxable income.
Fundamentals
- •The basic accounting equation (Assets = Liabilities + Equity) and the accounting cycle from journal entries to financial statements
- •The distinction between commercial accounting profit and fiscal taxable income, and the positive/negative adjustments made in fiscal reconciliation
- •Main corporate tax categories: corporate income tax, withholding taxes (21/23/26/final), and VAT

Frequently Asked Questions
What is the difference between PPh 21, PPh 23, and final income tax?
PPh 21 is withheld from employee income, PPh 23 is withheld on service/rental/dividend transactions between domestic taxpayers, while final income tax applies a fixed rate to specific income types and is not combined with other taxable income.
What is the TER method for PPh 21?
TER (Average Effective Rate) is a simplified method for calculating monthly PPh 21, introduced under PMK 168/2023, where the rate is determined by a gross monthly income bracket and PTKP category.
