DEAR HARRY: I went to a "professional" (a storefront preparer) to prepare my tax return back in 2002. For whatever reason, he did not deduct my real-estate taxes. In subsequent years, I used his work as a guide in preparing the returns myself, so I got no deduction all these years.
On April 10, I filed an amended return for 2009, 2010 and 2011, the "open years." Of course, I did the right thing on my 2012 return. I lost the deduction for the years from 2002 through 2008. Would I gain anything by amending my Pennsylvania returns for these years? It does not appear to me that real-estate taxes are a factor in determining the Pennsylvania tax.
