It was a busy tax year for Bend preparer Marge Hotz. This year she did about 500 returns and 50 extensions, and some were a little more complicated because of the economy. Licensed Tax Preparer Marge Hotz of Bend has a warning for people thinking that filing an extension will solve a tax bill problem; it can cost you more money in the long run. Marge Hotz spoke with 1110 KBND’s Loir Raab: “We've done a few this year because people are afraid that they are owing money, and they think that's going to stop it, thru extensions, sorry that's not going to solve the problem. You still have to pay the taxes due.” LR: “Are there extra charges?” MH: “Yes there is; a late filing fee and penalty if you do not have a refund coming back and you owe tax, then you will have a penalty on that. Yes." The average federal individual tax refund for 2010 was $2,940.
