I've looked on the IRS site and the 2006 model year Honda Civic Hybrid is not certified for the Clean-Fuel Deduction in the 2005 tax year. So if you purchased it in 2005, like me, you might not qualify for either the Clean-Fuel deduction or the Energy Policy Act of 2005 credit. Yeah sucks. I submitted a formal request to the Taxpayer Advocate Service of the IRS. I suggest everyone in this situation submit a request to certify the 2006 Honda Civic Hybrid for the 2005 Clean-Fuel Deduction.
