The family circumstance deduction is one of the deductible amounts used to determine taxable income for Personal Income Tax (PIT) purposes. In addition to the deduction applicable to the taxpayer, a taxpayer may also claim deductions for qualified dependents, provided that the statutory conditions are satisfied.
In practice, many taxpayers question whether a husband or wife may be registered as a dependent for the purpose of claiming a family circumstance deduction, particularly where one spouse is unemployed, has no income, or has lost the capacity to work.
This article examines whether a spouse may qualify as a dependent, together with the applicable legal conditions, required supporting documents, and registration procedures under current Vietnamese tax law.
1. Can a Husband or Wife Be Registered as a Dependent?
Yes. Vietnamese personal income tax legislation permits a taxpayer to register his or her spouse as a dependent for family circumstance deduction purposes, provided that all statutory conditions are fully satisfied.
Pursuant to Point d.2, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC, a taxpayer’s husband or wife is expressly recognized as one of the categories of persons who may qualify as a dependent.
However, not every spouse automatically qualifies for the deduction. The spouse must also satisfy the eligibility requirements prescribed in Point đ, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC.
Furthermore, Article 19 of the 2025 Law on Personal Income Tax, effective from 1 July 2026, continues to provide that taxpayers are entitled to family circumstance deductions in respect of qualified dependents in accordance with applicable law. Accordingly, the determination of whether a spouse qualifies as a dependent continues to be governed by the existing implementing regulations until superseding guidance is issued.
2. Conditions for a Husband or Wife to Qualify as a Dependent
Under Point đ, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC, the applicable conditions differ depending on whether the spouse is of working age or beyond working age.
2.1. Spouse of Working Age
Pursuant to Sub-point đ.1, Point đ, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC, a spouse who is of working age may only be recognized as a dependent if both of the following conditions are simultaneously satisfied:
- The spouse is disabled or suffers from a medical condition that renders him or her incapable of working; and
- The spouse has no income, or his or her average monthly income from all sources during the tax year does not exceed VND 1 million per month.
For these purposes, a person incapable of working refers to an individual whose disability or medical condition resulting in loss of working capacity has been certified by a competent authority through the prescribed documentation.
Accordingly, if a spouse is of working age, remains physically capable of working, and has normal working capacity, the fact that he or she is currently unemployed or earns no income does not, by itself, qualify that person as a dependent.
2.2. Spouse Beyond Working Age
Pursuant to Sub-point đ.2, Point đ, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC, less stringent conditions apply to spouses who are beyond working age.
In such cases, the spouse only needs to satisfy one of the following conditions:
- Having no income; or
- Having an average monthly income from all sources during the tax year not exceeding VND 1 million per month.
Unlike spouses who are of working age, individuals beyond working age are not required to prove disability or incapacity for work.
3. Circumstances Where a Spouse Does Not Qualify as a Dependent
A spouse with a low income does not automatically qualify as a dependent.
Under the current regulations, a husband or wife is not eligible for family circumstance deduction if any of the following circumstances apply:
- The spouse is of working age and has normal working capacity;
- The spouse’s average monthly income during the tax year exceeds VND 1 million;
- The taxpayer fails to provide the required supporting documents evidencing dependent status;
- The spouse has already been registered as a dependent by another taxpayer during the same tax period.
Accordingly, unemployment or a relatively low income alone is insufficient to establish dependent status for family circumstance deduction purposes.
4. Supporting Documents for Registering a Spouse as a Dependent
The supporting documents required to substantiate a spouse’s dependent status are prescribed in Point g, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC.
The taxpayer is generally required to submit the following documents:
- A copy of the Marriage Certificate or other lawful document evidencing the marital relationship;
- Where the spouse is of working age, documentation proving incapacity for work, such as a disability certificate issued in accordance with the law on persons with disabilities or medical records demonstrating a medical condition resulting in incapacity for work;
- Any additional documents requested by the tax authority in specific circumstances.
Preparing complete and accurate supporting documentation facilitates the dependent registration process and subsequent tax finalization.
5. Procedures for Registering a Spouse as a Dependent
Pursuant to Point c, Clause 1, Article 9 of Circular No. 111/2013/TT-BTC, a taxpayer must register his or her dependent with the tax authority in order to claim the family circumstance deduction.
In practice, the registration is generally carried out through the taxpayer’s income-paying organization or directly with the tax authority where the taxpayer conducts his or her own annual tax finalization.
Following registration, the dependent will be issued a tax identification number where required. The taxpayer is entitled to provisionally claim the family circumstance deduction from the date of registration in accordance with the applicable regulations.
Where registration is not completed during the relevant tax year but all statutory conditions are satisfied, the taxpayer may still register the dependent when filing the annual personal income tax finalization in accordance with the guidance of the tax authority.
6. Family Circumstance Deduction Amount Applicable from 1 July 2026
Under Article 19 of the 2025 Law on Personal Income Tax, effective from 1 July 2026, the family circumstance deduction amounts are adjusted as follows:
- Deduction for the taxpayer: VND 15.5 million per month (equivalent to VND 186 million per year);
- Deduction for each qualified dependent: VND 6.2 million per month.
Accordingly, where a husband or wife satisfies all statutory requirements to qualify as a dependent, the taxpayer may claim an additional family circumstance deduction of VND 6.2 million per month in determining taxable income.
7. Practical Considerations When Registering a Spouse as a Dependent
To minimize the risk of rejection of the registration dossier or subsequent tax reassessment, taxpayers should take note of the following:
- Register a spouse as a dependent only where all statutory conditions are fully satisfied;
- Prepare complete documentation evidencing both the marital relationship and the spouse’s eligibility as a dependent;
- Regularly monitor the dependent’s income to ensure continued compliance with the prescribed income threshold throughout the deduction period;
- Complete the registration within the prescribed time limit and retain all supporting documents for inspection by the tax authority;
- Promptly update the registration if the spouse no longer satisfies the statutory eligibility requirements.
Submitting inaccurate declarations or relying on insufficient supporting documentation may result in tax reassessment, late payment interest, and other administrative sanctions under the tax administration legislation.
