Year-end Equity Tax Forms: 3921,1099-NEC, W-9 collection

The common year-end tax forms startups handle for equity and contractors. 

At the end of the year, startups typically handle a few recurring tax forms tied to equity and contractor payments. This is an operational overview, not tax advice. 

Common Forms

Form 3921: Filed for employees who exercised incentive stock options (ISOs) during the year.

Form 1099-NEC: Issued to U.S. contractors paid above the reporting threshold.

Form W-9: Collected from contractors and vendors up front so that you can issue 1099's correctly. Collect W-9's as you onboard contractors  so year-end reporting is straightforward.
