Hi all,
Mr. A is government employee. His income is taxable. Out of that taxable income he transferred ₹ 300000 to his spouse.
Spouse is house wife. She invested that ₹ 3,00,000 in fixed deposit. She earned interest ₹ 20,000.
Now my query is
1. In hands of wife which income is taxable 320000 or 20000. If 20000 is taxable, under which section ₹ 3,00,000 is not taxable.
Or
2. Clubbing provisions if any applicable to Mr. A
