Why do you want to cook such stories instead of that you should have filed her income tax return every year and shown some profit.
What were you showing as income in earlier years, because in 7 years it's not easy to save 9 lakh for a housewife.
Now you need to just say that 9 lakhs were her savings over the period of time.
Regarding the sale of jewellery, if you say she has sold the jewellery then you should have shown capital gain income in her return of income. If you have not shown such income then you will also have to pay penalty on such income.
You will first have to tell the actual source of such income so that we can think of something.
If you are starting an FD or investing in mutual fund above 5-10 lakh obviously there would be a scrutiny in that case.
Hope you find the above information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you.
