The four questions behind every 1099-NEC
A 1099-NEC reports nonemployee compensation: money you paid, in the course of your business, to a person who is not your employee, for services. Four things decide whether you file one: was it for services rather than goods, is the payee a corporation, did you pay by card or payment app (those are reported on Form 1099-K by the processor), and did the total for the year reach the reporting threshold.
The threshold rose to $2,000 in the current IRS instructions; for payments made in 2025 and earlier it was $600. The checker defaults to the figure on irs.gov and lets you edit it, so you can check an earlier year too.
