Guide to Filing the Latest Corporate Annual Tax Return

Paying taxes on time is an essential responsibility for every law-abiding citizen. Taxes play a crucial role in national development, and one way businesses contribute is by submitting their Corporate Annual Tax Return (SPT Tahunan Badan) on time.

Indonesia follows a self-assessment system for tax reporting, meaning that taxpayers are responsible for calculating and reporting their own taxes. This system ensures compliance with regulations while helping businesses maintain financial transparency.

Many companies find corporate tax reporting complex and time-consuming, particularly due to the numerous documents required. However, modern solutions such as Coretax and digital signatures can simplify and accelerate the process.

This guide covers everything you need to know about Corporate Annual Tax Returns, including requirements, filing steps, and how technology enhances efficiency and security in tax reporting.

This tax report serves as a financial transparency tool while ensuring that businesses fulfill their tax obligations. Companies such as PTs, CVs, organizations, and foundations must file the return using Form SPT 1771.
