1. Background and Establishment:

The Ogun State Internal Revenue Service (OGIRS) was established by the Ogun State Government to consolidate and manage the state’s revenue generation efforts efficiently. It was founded with the primary aim of enhancing revenue collection, plugging revenue leakages, and providing a conducive environment for taxpayers to fulfill their tax obligations seamlessly.

This includes Personal Income Tax (PIT), Corporate Income Tax (CIT), Value Added Tax (VAT), Withholding Tax (WHT), Capital Gains Tax (CGT), and other state-specific taxes. The agency ensures that tax assessments are accurate, tax payments are made promptly, and tax compliance is maintained by individuals and businesses.

b. Taxpayer Education and Enlightenment: OGIRS places significant emphasis on taxpayer education and enlightenment programs.
