Tomorrow (Aug. 15) is the formal due date for refund of 2012 property taxes. Now, there’s no need to panic if you or your tax advisor haven’t filed that return yet. The state Department of Revenue says homeowners and renters will get a grace period of one year, pushing out the effective deadline for filing a 2012 return to Aug. 15, 2014. But, if you haven’t filed for a refund of your 2011 property taxes, you will have to rush. That refund expires tomorrow. Submit Form M1PR by the end of the day
