Dept. of Maybe-Not-So-Unintended Consequences: Doesn't Obamacare create a big new incentive to fudge your income on your tax returns? The subsidies available on the health care exchanges seem to be based on adjusted gross income (line 37 on Form 1040)-- and there's a huge, conspicuous difference between the subsidy available at, say, a $25,000 income and a $46,000 income. (The subsidy cutoff of is $45,960 for a single person). In California, for the "bronze" policy I'm interested in, at $46,000 I'd pay $507 a month. At $25,000 I'd pay ... $63. A difference of $444 a month.
