Regarding the regulation raising the threshold for exemption from personal income tax and value-added tax for individual businesses from VND 200 million to VND 500 million per year, Mr. Huy requested that the authorities confirm the official date of application of this threshold (from the 2026 tax year or according to a specific timeframe in the guiding document).

At the same time, in the case of an individual with multiple sources of income, including salary and income from renting out property (rental properties), how is personal income tax calculated? Should each source of income be taxed separately (salary subject to progressive tax rates; rental income subject to a fixed rate or based on actual income) and not combined when determining tax liability?

Regarding this matter, the Tax Department of Ho Chi Minh City has the following opinion:

Based on the Law on Personal Income Tax dated December 10, 2025, enacted by the National Assembly :

Article 3 specifies taxable income:

"1. Income from business activities, including:

a) Income from the production and sale of goods and services;

… 2. Income from salaries and wages, including:

a) Salaries, wages, and other payments of a similar nature.

Article 7 stipulates the personal income tax on income from business activities;

Article 8 stipulates the personal income tax on income from salaries and wages;

Article 29 of the implementing provisions states:

"2. Regulations relating to income from business activities, salaries, and wages of resident individuals shall apply from the tax year 2026."

Based on Government Decree No. 68/2026/ND-CP dated March 5, 2026, regulating tax policies and tax management for business households and individual businesses;

Based on Circular No. 18/2026/TT-BTC dated March 5, 2026, issued by the Minister of Finance, which regulates the documentation and procedures for tax management of business households and individual businesses;

Based on the above regulations, in the case of Mr. Le Tran Ba Huy, who has both income from salary and wages and income from business, he must file separate tax returns for each source of income as stipulated in Articles 7 and 8 of the Personal Income Tax Law 2025.

For property rental activities (rental properties), tax declaration and payment shall be carried out in accordance with the regulations in Decree No. 68/2026/ND-CP and Circular No. 18/2026/TT-BTC.
