I got my state and federal tax refunds yesterday. It appears that in additional to failing to sign my state income tax return, I copied one of the numbers wrong when preparing the final version from a draft. As a result New York State thought I had made an arithmetic mistake and reduced my refund accordingly. Fortunately this was not too difficult to correct. I had to spend 20+ minutes on hold with the New York tax department but they were then able to fix the problem without requiring me to submit an amended return. So part of my refund will be delayed a bit. Hopefully this just means I was bit tired when I finished the state return and is not further evidence of impending senility.
