Minnesota

MN return is so convoluted.

But I did get the letter and went in search of the correction. Since I used TurboTax I knew it was not my mistake but was curious.

We itemized our deductions and one could only deduct medical expenses that exceeded 7.5% of AGI. But MN set the bar higher to 10%. So one had to use a few more forms, of course, to add this 2.5%. (The new Federal "tax reform" now also uses the 10% bar).

The corrected form now removed that addition to income, reduced the taxable income and the tax and, in our case, increased the refund.

I do hope that the 2019 forms are not as bad as the 2018 but am doubtful. Yes, I use TurboTax but usually have my spreadsheet filled.
