Are tuition fees for children eligible for personal income tax deductions for the taxpayer? What is the maximum deduction amount?
Under current regulations, taxpayers may claim a personal income tax deduction for tuition fees paid for their children. However, the following conditions must be met:
(1) The taxpayer must be a resident individual as defined in Article 4 of Decree 253/2026/NĐ-CP.
(2) The child for whom the tuition fees are paid must qualify as a dependent in accordance with the law. Specifically, the regulations regarding personal income tax deductions for taxpayers concerning their children’s tuition fees are set forth in Point b, Clause 2, Article 49 of Decree 253/2026/NĐ-CP, as follows:
Deductions for charitable and humanitarian contributions and other deductions
- Resident taxpayers are entitled to deductions from taxable income—prior to the calculation of tax on income from salaries and wages—for medical and educational/training expenses incurred by the taxpayer and their dependents, including:
- a) Expenses for medical examination and treatment at domestic medical facilities that fall within the scope of coverage by health insurance, with a total limit of 23 million VND per year;
- b) Expenses for education and training at domestic educational and training institutions, with a total limit of 24 million VND per year; specifically: tuition fees for preschool education, general education, vocational education, and higher education in accordance with the law on education and training, as well as fees for other professional skills training at educational and training institutions.
Accordingly, a resident taxpayer is entitled to a personal income tax deduction of up to 24 million VND per year for their child’s tuition fees, provided the child is registered as a dependent.
What are the principles governing personal income tax deductions for taxpayers who have children registered as dependents? Pursuant to the provisions of Clause 2, Article 48 of Decree 253/2026/NĐ-CP, the principles for personal income tax deductions for taxpayers with dependent children are detailed as follows:
– Taxpayers are entitled to a family circumstance deduction for a dependent child if they have completed tax registration and dependent registration. The deadline for registering a dependent and submitting supporting documentation is December 31 of the tax year; this registration remains valid for subsequent years unless changes occur.
– If a taxpayer has not yet claimed the family circumstance deduction for a dependent during the tax year, the deduction may be calculated starting from the month the obligation to support the dependent arises.
– Upon registering a dependent for the deduction, the family circumstance deduction is provisionally calculated for the year starting from the time of registration (calculated on a full-month basis).
– In cases where multiple taxpayers share the same dependent child requiring support, they must mutually agree to register the family circumstance deduction with only one taxpayer for the tax year. Any changes to this agreement shall apply to the subsequent tax period.
– Taxpayers with multiple sources of income from salaries or wages may choose where to register the family circumstance deduction for a dependent, provided that each dependent is claimed for the deduction only once against a single taxpayer during the tax year.
