What is a service code?
A service code is a special code that applies a discount to the TurboTax Online fee provided by our support agents for specific, pre-determined reasons. They aren't considered online coupons or "groupons".
We don't issue service codes for third-party discounts from affiliates like USAA because our affiliates have their own TurboTax-branded websites that automatically apply the discount. More info
Service codes are valid through October 15 and can be used only once. Returns will not accept multiple service codes.
