The big exception: the child's own skill
The general rule, covered in full on our clubbing page, is that a minor child's income is added to the income of the higher-earning parent under Section 64(1A). But the same section carries an important exception. Income that a minor earns from their own manual work, or from any activity that calls for their own skill, talent, specialised knowledge or experience, is not clubbed. It is taxed in the child's own hands, at the child's own slab.
This is what covers the child actor, the young sportsperson, the chess champion, the young musician or performer. If your minor child earns in India from their own talent, that income does not get stacked onto your income as the NRI parent, it stands on its own. There is one limit to keep in mind: only the earnings themselves escape clubbing. If those earnings are then invested and produce further income, say interest on the money the child earned, that later income is clubbed back with the parent under the normal rule.
The other exceptions, and who files
Two more situations take a minor's income out of clubbing. A minor who suffers a disability of the kind specified under Section 80U is assessed on their own income independently, not clubbed with a parent. And clubbing is only ever a rule for a minor, so the moment the child turns 18 it stops, and their income is their own from then on.
That raises a practical question: a minor cannot sign or file a return. Where the income is clubbed, there is nothing for the child to file, it goes into the parent's return. But where the income is the minor's own, the child-actor or disabled-minor cases, a return is filed on the minor's behalf, usually by a parent or guardian acting as the child's representative. For an NRI parent, the split matters: your child's talent income is taxed in the child's hands in India, often at lower slabs, while passive Indian income of the child, such as bank interest, is clubbed into your Indian return with the ₹1,500 per child relief. Getting each stream into the right return, and claiming the TDS in the right place, is what a practising CA sorts out.
