If you enrolled in the National Healthcare exchange last year, your tax refund may be delayed. A national taxpayer representative blames this delay on Obamacare subsidy pay-outs. Some individuals who enrolled in Obamacare got subsidies based on their estimated 2014 income. Early in the filing season, the I-R-S held some tax returns that involved Obamacare subsidies for review. As of last week those returns have been processed and filers have been contacted to provide more information. Some people may get more money back from their return and others may have to pay the government back.
