Gifts to children
The gift deduction renews every 10 years. If you give KRW 20 million at birth, KRW 20 million at age 10, KRW 50 million at age 20 and KRW 50 million at age 30, you can give KRW 140 million with no gift tax, and the returns that grow in the meantime belong to the child.
Enter your child's current age and it calculates the deduction limits available in 10-year cycles from now.
Assuming the gifted money is invested in an account in the child's name, it calculates the amount at the target age.
Even when within the deduction limit, filing a gift tax return makes it easier to prove the source of funds later.
There is no tax to pay because it is within the deduction limit, but it is a good idea to file. Later, when the child buys a home or builds a large asset with that money and its gains, you can prove the source of funds.
Gift tax is determined on the amount at the time of the gift, and the gains that later arise in the child's account are the child's income. However, if the child's name is only borrowed and the parents actually manage and use the account, it may be treated as property held in a borrowed name.
The lineal ascendant deduction has the same 10-year limit for parents and grandparents combined. For gifts that skip a generation, a 30% surcharge (40% for minors when the amount exceeds KRW 2 billion) is added to the calculated tax.
