<p>A friend of mine told me that she plans to deduct the state income tax that she paid for deficiency payment from prior years. I thought that interest or penalties are not deductible, and for me , that make sense. </p>
<p>Anyone here knowledgeable about this!</p>
<p>I swear I’ve research this topic for many hours now, and can’t seem to find an article or anything that talks about being able to deduct such payment in schedule A.</p>
