Are timely filing discounts on Retail Sales tax returns considered income?

[Snoopy70]

SC requires us to file a retail sales tax return each month. Timely filing of the return results in a small discount. My bookkeeper (QuickBooks Live) is listing these discounts, as well as credit card cash back, under Other Income on the Profit and Loss Statement.

I'm 99% sure that cc cash back is considered a rebate and is not taxable.

I'm hoping someone can tell me if the same applies to the Timely Filing Discounts SC gives businesses when filing the return early.
