The average tax penalty among H&R Block customers is $383 for remaining uninsured last year, up from $172 for 2014, and 60% of those who received Affordable Care Act tax credit must repay some of that money, the tax preparation firm said. Penalties will rise higher for people who do not carry insurance throughout 2016, but many people are struggling to estimate this year’s income, H&R Block Vice President Mark Ciaramitaro said.
