1. Limit as per sec 269SS is Rs. 20,000 (in cash) in aggregate per person in a day as loan or deposit or any other sum.
2. Limit as per sec 269ST is Rs. 2,00,000 for receiving any amount in cash in aggregate per person in a day. However, this rule will not be applicable for banks and governments.
3. Any type of business payments per day to a single person should not exceed Rs. 10,000 in cash. So vendor payment should not exceed Rs. 10,000 in cash. This is as per sec 40A(3). Payment in excess of Rs. 10,000 will attract disallowance while computing PGBP.
Please correct me if the above solution has an alternative view.
