My wife is a homemaker. She has bank FDs. Should she file income tax return?

For getting interest without deduction of tax at source, non-senior citizens can file form 15G and senior citizens have to file form no. 15H. Since your wife is not a senior citizen, she has to file form no. 15 G. But she has to file her ITR only if her income during the year exceeds the amount of basic exemption of Rs. 2.50 lakh
