Can you say: byzantine? ACA will be a full employment act for accountants. At this point, I have a headache just trying to figure out where I'll stand in 2014.
Get a grip. I think you overstate the complexity. Just remember, the subsidy is based on MAGI (before deductions) and the deduction will likely be based on insurance premiums and health care costs paid just like has been for years.
If you get a refund or have to repay under the subsidy you would reduce or increase next year's deduction - just like we do today for the state income tax deduction.
In principle, the subsidy true-up works just like actual and estimated taxes and taxes due or refunds work today and the deduction will work just like state income tax deductions work today. Easy.
