Deductions & credits

Hello JohnW222,

I have a similar situation. For 2019 tax year, my wife contributed $3,000 to HSA via payroll deduction.  Her employer contributed $750. The total of $3,750 is shown in Box 12 with code W.

 

My issue/question is: 

The entire amount of $3,750 is showing up as Additional Income (Schedule 1, Part I, Line 8.   

In a similar situation for 2018 tax year, none of the contribution appeared as taxable.

We did earn more in 2019 than 2018. Could an AGI cap for HSA deductions be the cause? We file MFJ

Thanks!
