Tax Error Complicates Financial Help for Some With Obamacare - ABC News
If you do not file taxes and you are receiving a subsidy or are on Medicaid via the ACA, even if you are not otherwise required to do so, you will not qualify for your subsidies in 2016. Also, if you chose to buy an individual plan not on the exchange and you would have otherwise qualified for subsidies, make sure you account for that on your taxes as well or you will not qualify for subsidies in the future. There is free tax assistance just about everywhere for low income people, Turbo Tax and others have free online tax filing for low income or even those just filing a 1040EZ or a 1040A.
