No specific instructions as such mentioned by the ITD.
This is the bare text form section 285BA section read with rule 114E.
"
Payments made by any person of an amount aggregating to—
(i) one lakh rupees or more in cash; or
(ii) ten lakh rupees or more by any other mode,
against bills raised in respect of one or more credit cards issued to that person, in a financial year."
"
From a plain reading, it can be interpreted that they are referring to payments made against the credit card bill. However, a bank can adopt a different approach and consider the total purchases made in a financial year in its calculation. We don't have any case law yet to get a proper analysis of the text.
As a safe approach I will suggest that one should make sure that
1) Their Debit transactions are under 10L, ignoring any reversal of that debit transaction.
2) Total Amount of Bills raised during the year is less than 10L
3) Total Credits(Payments) are under 10L.
It's worth noting that your income should ideally match your expenses. If you can justify your expenses and have a legitimate source of income to cover them, you should not have to worry about such reporting.
