What type of payment would I categorise cash back from my bank as? Assuming income but these small amounts won’t be taxable?

Hi info-cranemainta!

I can help with technical support in QuickBooks, including guidance on entering transactions. However, advising on how to categorize your cash back and whether it's taxable is more of an accounting question. I suggest consulting an accounting professional for assistance with this matter. 

On the other hand, if you encounter challenges in reflecting your accountant's instructions in QuickBooks, feel free to reply here, and I'll be happy to provide further assistance.
