Hello, 

The state income tax refund always confuses me. 

In 2022, I had $10,453 in state income taxes that was limited to $10,000 due to the SALT cap. 

I had $7,476 in interest expense and $600 in charitable contributions. 

Therefore, all in all, I had $18,076 in charitable deductions. 

This year, I received a 1099-G for $691. Is that $691 refund taxable?
