While the GST Act itself does not set a specific monetary limit on cash sales, the Income Tax Act (Section 269ST) prohibits receiving ₹2 lakh or more in cash in aggregate from a person in a day, for a single transaction, or for a single event/occasion. Violating this limit can lead to penalties equal to the amount received. Key Cash Transaction Rules Under Income Tax Act (Relevant for GST Compliant Businesses): Maximum Cash Receipt: No person can receive ₹2,00,000 or more in cash from a single person in a day, or for a single transaction. Single Transaction vs. Daily Limit: Even if a sale is broken into multiple installments over several days, if it relates to a single transaction or event, cash exceeding ₹2 lakh is prohibited. Expenses in Cash: As per Section 40A(3) of the Income Tax Act, any business expenditure payment exceeding ₹10,000 in a single day to a single person must be made via banking channels (cheque/draft/e-transfer), otherwise, it is disallowed as a deduction. PAN Requirement: Any single cash deposit of more than ₹50,000 must be accompanied by a PAN or Form 60. Best Practices for Cash Sales: Issue Invoices: Always issue a GST invoice for cash sales, regardless of the amount. Maintain Records: Detailed records of cash sales (date, amount, customer details) are essential to ensure audit compliance. Avoid High-Value Cash: Keep cash transactions well below the ₹2 lakh limit to avoid penalties.
