Two out of three subsidized recipients of Obamacare had to repay all or part of their subsidies according to tax data released by H&R Block.
The average amount owed back to Obamacare by those who received too high a subsidy was $729. About a quarter of those who received subsidies were under-subsidized by an average of $425.
Policymakers have expressed concern that low-income people could struggle with paying back the subsidies — or suffer if their tax refunds are greatly reduced because of overpayments.
The figures differ from estimates released last month by the Kaiser Family Foundation, which projected that about half those buying subsidized Obamacare plans would owe a payback and half would be owed a refund.
