You can only take a 179 Deduction on an newly purchased Asset that is first being used for Business in 2023.
If you are trying to take a 179 deduction for an asset when you shouldn't be, you may get this message.
You can review the Asset Entry Worksheets for any new assets you entered this year to see which may not qualify for 179, and delete/re-enter the asset, not choosing 179.
