Real-world case study: Optimizing personal income tax obligations for household businesses renting out premises.
Analyzing a real-world case in Vietnam helps clarify the choice of revenue recognition method and provisional personal income tax payment.
Specific business situation
Mr. Tran Van B's business operates in the field of warehouse rental in Ho Chi Minh City. In January 2026, Mr. B signed a contract to rent a warehouse to company C for a period of 3 years (from 2026 to 2028).
The total rent for 3 years is 1.2 billion VND. Company C paid 100% of the rent upfront upon signing the contract.
According to regulations, the personal income tax rate for property rental activities is 5%. Mr. B's business is currently filing VAT returns and making quarterly provisional personal income tax payments.
Analyzing two options for declaring personal income tax.
Based on point d, clause 2, Article 5 of Decree 68/2026/ND-CP, Mr. B chooses one of two options:
Option 1: Allocate revenue annually (over 3 years)
- Taxable revenue per year: 1.2 billion / 3 years = 400 million VND/year.
- Taxable revenue per quarter: 400 million / 4 quarters = 100 million VND/quarter.
- Provisional personal income tax payable each quarter: 100 million x 5% = 5 million VND.
- Total tax paid over 12 quarters: 5 million x 12 quarters = 60 million VND.
Option 2: Determine revenue from a one-time payment.
- Taxable revenue recorded as a lump sum in Q1/2026: VND 1.2 billion.
- Provisional personal income tax payable for Q1/2026: 1.2 billion x 5% = 60 million VND.
- For the remaining quarters of 2026, 2027, and 2028: The amount of provisional tax payable is 0 VND.
An assessment from a cash flow management perspective.
Option 1 allows homeowners to retain 55 million VND in taxes that are not immediately payable in Q1/2026 to maintain liquidity and reinvest in infrastructure.
Option 2 ensures the complete fulfillment of the contract's tax obligations, completely eliminating the risk of discrepancies arising from tax policy adjustments in subsequent years.
