Understanding tax chapter codes and sub-item codes helps businesses file declarations accurately and avoid costly errors.
What Are Tax Chapter Codes and Sub-Item Codes?
In Vietnam’s tax administration system, “tax chapter codes” and “sub-item codes” play a key role in classifying, identifying, and accounting for state budget revenues. These codes are used to accurately identify taxpayers and the specific types of taxes they are required to pay. Understanding and correctly applying these codes not only helps businesses file taxes accurately but also prevents administrative penalties caused by errors. This article explains the nature, function, and practical application of tax chapter and sub-item codes.

What Is a Tax Chapter Code? Meaning and How to Identify It
1. Definition of Tax Chapter Code According to the Ministry of Finance
A tax chapter code is a numerical code used to identify the organization or entity paying into the state budget, reflecting its role in the government structure or the economy. Under Circular 324/2016/TT-BTC issued by the Ministry of Finance, the tax chapter code consists of four digits and is individually assigned to each administrative, public service, business, or financial unit.
2. Common Tax Chapter Codes for Businesses
Businesses and individuals are typically assigned chapter codes based on the following groups:
-Chapter 754: Mixed economy outside the state sector.
–Chapter 755: Private enterprises.
–Chapter 756: Cooperatives.
–Chapter 757: Household businesses and individuals.
Depending on the type of business and its governing agency, the chapter code is categorized accordingly to determine accurate budget obligations.

What Is a Sub-Item Code? How to Distinguish and Apply It
1. Definition of Sub-Item Code in Vietnam’s Tax System
A sub-item code specifies the economic content of a particular revenue or expenditure item in the state budget. It identifies the exact source of revenue (such as corporate income tax, VAT, fees, and charges) or the purpose of a budget expense. Each sub-item code consists of four digits and is listed within the national budget index system.
2. Key Sub-Item Codes to Know
Common sub-item codes include:
-Sub-item 1701: Value Added Tax (VAT).
–Sub-item 1001: Personal Income Tax (PIT).
–Sub-item 1052: Corporate Income Tax (CIT).
–Sub-item 2862: Business license tax – Tier 1.
–Sub-item 2863: Business license tax – Tier 2.
–Sub-item 2864: Business license tax – Tier 3.
Businesses must identify the appropriate sub-item code that corresponds to each tax obligation to ensure accurate accounting.
