How long you have to refund a client depends on how they paid. Refunds always go back to the original payment method.
Card Payments
There's no 180-day cutoff for card payments. You can refund to the original card months after the charge. Refunds issued more than a year after the original payment have gone through.
ACH Payments
ACH (bank) payments can be refunded within 180 days (about 6 months) of the original payment date. If you plan to refund an ACH payment, issue it within 180 days of when the client paid.
