Per bank. If it crosses that limit bank has to report that cash payment.
Official rule:
Payments made of an amount adding to Rs 1 lakh or more in cash towards credit card dues must be reported, states CBDT. Further, if one pays Rs 10 lakh or more to settle credit card dues in a financial year (in any mode), these transactions too need to be reported to the income tax department.
These rules are per bank, note: axis bank doesn't have your information related to ICICI bank, so take care each bank separately.
