I filed a 1040NR-EZ tax return. Only after I mailed it, I realized that I had an HSA which requires Form 8889 and the non-simplified 1040NR to be filed. My W-2 does show a W contribution in Box 12.
If I file an amended return, the refund won't change since my own HSA contribution was $0.01 (how funny is that?) and my employer's HSA contribution is just a two-figure number.
Is it necessary to file an amended return? If the amounts were larger, I would do this straight-away, but for just a $0.01 change in the AGI I'm not sure if this is worth the effort (on my as well as on IRS's side)? The IRS should've received my 1040NR-EZ about four weeks ago but I haven't heard anything from them yet.
