If you are domiciled in NY and earn as a private entity, then you are not domiciled in DC or a federal worker there, meaning (from a tax honesty perspective) you are not legally required to pay or file. The system makes it appear as if you are, due to prejudicially worded information reports and documents that track your private activity, to make it seem you are liable and subject to their jurisdiction, whether you are or not. The trick if you take the honesty path is to not facilitate creating that paper trail and tracking process as much as possible.
If you feel you are not subject to income taxes (i.e., the IRS is not the be-all and end-all determiner as to what, or if you owe), as the path of least resistance, create multiple faux IDs and stay under the $600 earning radar per each program. You can also consider getting a foreign maildrop address and receive your payments by check.
