If I am unemployed how do I answer the question “do I plan to file federal taxes”?
When you project your income for ObamaCare's cost assistance you need to attest to the amount of income you expect to claim and whether or not you plan to file taxes. If you expect to gain employment you'll want to estimate income with that in mind. You won't have to file taxes if your income is below the filing threshold, but you may choose to anyway. Thus, if you know you will file federal taxes then you should answer "yes" to the aforementioned question. When you are unemployed and don't know if you'll gain employment you may want to take part or none of the Advanced tax credits up front. This will help avoid repaying tax credits if your income is higher than expected.
