Deadline for personal income tax settlement in 2026 for organizations and individuals.
Determining the deadline for personal income tax settlement in 2026 depends on whether the entity settling the tax is an organization paying income or an individual directly settling with the tax authorities. This differentiation aims to facilitate the tax authorities in processing the enormous volume of documents in a systematic manner.

Specifically, the deadline will be March 31, 2026. If this date falls on a public holiday or weekend, the deadline will be moved to the next working day.
For individuals who directly settle their tax obligations with the tax authorities.
Individuals with income from multiple sources of salaries and wages, or those who have overpaid taxes and wish to claim a refund, must handle the procedure themselves. The timeframe for this group is generally more relaxed compared to businesses.

Changes to personal allowance deductions in 2026
When filing personal income tax returns within the 2026 tax settlement deadline, the personal allowance is a key factor in determining the amount of tax payable.

Specifically, personal allowance for the taxpayer themselves has been raised to the level 15.5 million VND/month (replacing the previous amount of 11 million VND). Simultaneously, the deduction for each dependent has also been adjusted upwards accordingly (expected to reach approximately 6.2 million VND/month).
