In the Budget of 2021, the lawmakers reduced the maximum time you were allowed to file your Income Tax Return, by three months. Consequence? Now, you can not file your belated return after 31st December, even after paying double penalty to file your return of income.
You can still file your return of Income, aka Belated Income Tax Return.
Here is the thing, earlier the government collected the penalty in two tiers. For the "belated returns" that are filed within 31st December, the penalty was Rs 5,000 and for those filed within 31st March, the penalty was Rs 10,000.
Point is, you could file your return by 31st March after paying a penalty of Rs 10,000.
So, technically they have just eliminated the "3 months" and the "extra penalty of Rs 5,000" provisions, they have shifted the pressure on you for filing your return of income quicker.
Now, you can not file your belated return after 31st December, even after paying double penalty to file your return of income.
Amonng many things, you may not be able to claim depreciation, carry forward losses or claim a refund of income tax.
So, to summarize, you need to file your return of income quicker.
