Did you purchase a flex fuel vehicle between 2010 and July 2013? If so, you may be entitled to an income tax credit after all.
On May 14, 2014, the Board of Tax Appeals granted the first flex fuel credit in that matter Bolotte v. LDR, BTA #8007. The decision essentially states that because LDR interpreted La. R.S. 47:6035 as including flex fuel vehicles and that law did not change until July 2013, which was to specifically remove the flex fuel vehicle from qualifying, the credit must be allowed until the July 2013 amendment.
Income tax periods 2010 and forward are still open in order to claim the credit. In order to preserve your rights to claim a flex fuel credit for a 2010 purchase, you should act prior to December 31, 2014. LDR will deny the credit and you will need to appeal the denial within 60 days of notice. If you have already claimed the credit but failed to appeal within the 60 days, you may still file a claim against the state.
