If your output tax is less than your input tax credit (ITC), your GST payable is nil. You should still claim the full ITC amount in your GSTR-3B. If you filed a nil return in a previous month due to no sales or purchases, but had ITC available in GSTR-2B, you can carry forward this unused ITC to the next month's GSTR-3B filing.
