i received long term disability insurance i had federal withheld I did not have state withheld.the insurance co. has WI in box 15. i also received social security in 2018. the fact that it states wisconsin is this going to be an issue?
It will depend on the amount of the distribution reported to WI. If you are not a resident of Wi, and the amount reported is $2,000 or more, you will need to file a WI non-resident tax return and show that the distribution was not for WI. It is the same if you are a part-year resident of WI.
You should not have to pay any tax, just report that the income was earned in your state of residence.
If you choose not to file a WI tax return, you will probably receive a letter from WI asking for the return, or for money. You can respond with that fact that you were a resident of your state when the money was received.
Or you can ask the insurance company to correct the W-2. If you are continuing to receive the long-term disability payments, you will want to get the state corrected for 2019, if not for 2018.
