Tax reporting is an essential part of business operations, ensuring legal compliance and financial transparency. With several tax types to manage, including Value-Added Tax (VAT), Personal Income Tax (PIT), and Corporate Income Tax (CIT), preparing accurate and timely tax reports can be a significant challenge. This article offers detailed guidance on tax reporting in Vietnam, the support services available, and key points to help you optimize the process.
What Is Tax Reporting?
Definition of Tax Reporting
Tax reporting is the process of declaring financial information, invoices, and tax obligations that businesses must submit to the tax authorities. The main tax types include Value-Added Tax (VAT), Personal Income Tax (PIT), and Corporate Income Tax (CIT). Filing tax reports is a mandatory requirement that ensures businesses comply with the law and maintain financial transparency.
Tax reporting is not only a legal obligation but also a way for businesses to demonstrate professionalism in financial management and build credibility with partners.
The Role of Tax Reporting in Business
Tax reporting plays a critical role in ensuring financial transparency. It gives the tax authorities the basis to assess a company’s financial standing and apply appropriate monitoring, inspection, or support measures. Accurate tax reporting also helps businesses maintain strong relationships with partners and banks, since financial transparency is a key factor when applying for loans or attracting investment.
Common Types of Tax Reports
Businesses are required to prepare and submit the following tax reports:
- VAT Report: Declaration of Value-Added Tax on a monthly or quarterly basis.
- PIT Report: Declaration of Personal Income Tax on salaries and other sources of income.
- CIT Report: Declaration of the company’s taxable income.
- Invoice Usage Report: A record of invoices issued during the reporting period.
Legal Requirements for Tax Reporting
Under Circular 39/2014/TT-BTC, every business engaged in production or trading must prepare and submit tax reports on time. This requirement applies uniformly to all types of businesses, from small household enterprises to large corporations. Non-compliance can result in significant penalties.
Tax Reporting Deadlines
Tax reporting deadlines depend on the type of business and the tax filing period. Companies file taxes monthly or quarterly based on their revenue or initial registration. In general:
- Monthly reports must be submitted by the 20th of the following month.
- Quarterly reports must be submitted by the 30th of the first month of the next quarter.

VAT Declaration Process
- Collect invoices and documents related to the purchase and sale of goods and services.
- Calculate VAT payable: Determine input VAT (paid on purchases), output VAT (collected from sales), and the net amount payable.
- Prepare the VAT return using the prescribed templates (Form 01/GTGT for the deduction method or Form 03/GTGT for the direct method).
- Submit the VAT return and payment through the electronic tax system.
VAT Filing Deadlines
- Monthly declarations: Due by the 20th of the following month.
- Quarterly declarations: Due by the 30th of the first month of the next quarter.
The filing frequency depends on the business’s revenue and tax registration status.

- Maintain organized invoice records for future tax audits.
