A child under 18 can hold investments, but they don't file their own return — the tax law folds their gains into a parent's. ProjectionWealth handles that with a single setting on the child's portfolio, so the family's tax comes out right.
Mark the portfolio as a child
Open the child's portfolio in Settings → Portfolios and set Relationship to Child with a Date of Birth under 18. That's what tells the app to treat the account as a minor's.
A minor's gains are clubbed into the parent's return under Section 64(1A) — not as a separate PAN. Defaults to the higher-earning parent.
A Child under 18 gets a Tax clubbed with field — pick the parent whose return the gains fold into.
Choose who the gains club into
Once the child is a minor, a Tax clubbed with field appears. Pick the parent — Select a parent from your Self or Spouse portfolios. From then on the minor's gains are added to that parent's return under Section 64(1A), not taxed as a separate PAN, and no separate exemption applies.
Note: Clubbing usually defaults to the higher-earning parent. This affects how the combined family tax is totalled — the minor's row is marked so nothing gets double-counted. Confirm the specifics with a CA.
