Corporate Income Tax (CIT) Compliance * **Self‑Assessment System:** * Companies determine their own taxable income, file an annual CIT return and calculate tax liability. * **Annual Return Deadline:** * **30 April** for calendar‑year taxpayers (30 days after the fourth month following year‑end) * **Advance Tax Payments:** * Quarterly provisional payments due on the **17th day** of the second month following each quarter; these are offset against the final liability * **Payment Deadline:** * Final CIT is payable by **30 April**, concurrent with the annual return deadline . --- ## 3\.
