And there's certainly a desire to avoid fraud given that schedule of payments, if I'm correct about it.But why is it any different than the desire to avoid fraud through underwithholding of income tax?
If someone files an in incorrect W-4 and underwithholds by $2000, then the Treasury is out $2000. If someone files a fraudulent insurance application and gets $2000 of unwarranted subsidy, then the Treasury is also out by $2000.
It's the same $2000, whether the Treasury writes some checks to the insurance company, or fails to collect it from an individual on his paychecks. Either way, the $2000 gets paid back on the tax return -- or the IRS goes after you.
> Erk: if you're right about estimates and it depending on that years tax return; what do you do if you lose your job and can't afford to pay the unsubsidized rate? What if you earn a lot more money, spend too much of it, and then get hit with a huge bill next April 15th?
Again, not different in principle from income tax withholding. If you do not withhold the right amount, then you may get hit with a big bill or receive a big refund when you file your 1040.
The main difference is that the subsidy does not automatically adjust. Withholding tends to automatically go up and down with income, because it's calculated by the employer on the paycheck. Whereas the insurance subsidy stays constant unless you make changes.
If you lose your job, you're supposed to tell the exchange so that you can get a bigger subsidy. If your income goes up, you're supposed to tell the exchange so that you can get a smaller subsidy.
