🧾 Annual CIT Finalization Return
(Tờ khai thuế quyết toán thuế thu nhập doanh nghiệp – CIT)
💡 Understanding the Annual CIT Finalization Return
At the end of every fiscal year, enterprises in Vietnam are required to prepare and submit an Annual Corporate Income Tax (CIT) Finalization Return to the tax authorities. This return determines the company’s final tax obligations, reflecting actual profits, deductible expenses, and any adjustments or tax incentives.
Filing this declaration accurately and on time is a legal requirement under Vietnamese tax law. Failure to comply may result in administrative penalties, back taxes, or late payment fines — all of which can significantly impact business operations and financial credibility.

⚠️ Common Mistakes in CIT Reporting
- Data Errors in Financial Reports:
One of the most common issues is incorrect figures in accounting records or data input. This includes:
-
- Entering the wrong amounts from accounting systems.
- Using supporting documents that do not reflect the true nature or transaction value.
- Forgetting to declare or incorrectly declaring import/export taxes.
- Incorrect exchange rate conversion for foreign currency transactions.
Even small mistakes can cause major discrepancies between accounting reports and tax declarations, leading to audits or accusations of underreporting income.
- Missing Information or Supporting Documents
Incomplete or missing documents during tax filing can lead to tax authorities requesting additional clarification or even re-filing.
Common examples include:
-
- Missing salary registration tables or signed payroll sheets.
- Missing supporting schedules attached to the CIT return.
- Incomplete explanation for tax-deductible expenses.
- Ensuring sufficient documentation not only saves time but also protects businesses from future disputes.

🧩 Key Components of the CIT Finalization Dossier
A standard CIT finalization package typically includes:
- CIT finalization return – Form 03/TNDN
- Annual financial statements
- Appendices on business performance results
- Other related appendices

⚙️ Step-by-Step Process of CIT Declaration
Step 1: Choose the Suitable CIT Declaration Method
Depending on the business nature, enterprises can choose between:
- Quarterly provisional declaration (Form 01A/01B-TNDN) – for enterprises with regular operations.
- Per-transaction declaration – for cases involving asset transfers, M&A, or project liquidation.
Step 2: Ensure Timely Submission and Payment
According to Vietnamese tax law:
- CIT provisional tax must be declared no later than the 30th day of the following quarter.
- Annual CIT finalization must be submitted within 90 days after the end of the fiscal year.
- The total provisional payment during the year must be at least 80% of the total annual CIT payable to avoid penalties.
