Cognex RSU tax guide (CGNX)

Federal supplemental withholding, state tax, and trailing nexus rules on Cognex RSU vestings for tech employees.

About Cognex equity

Cognex (CGNX, HQ MA) grants RSUs to employees and also runs an Employee Stock Purchase Plan with a annual vesting cadence.

Federal withholding at vest

Cognex applies the standard federal supplemental withholding: 22% flat on RSU ordinary income, rising to 37% once year-to-date supplemental wages exceed $1M. Both rates are below the top bracket, which means high earners typically owe additional federal tax at filing.

State withholding

Because Cognex is headquartered in MA, your state withholding defaults to that state unless your work location is recorded differently. If you moved during the grant-to-vest window, the state that taxes each tranche is determined by workday allocation, not by your HQ.

Quarterly estimates

Tech earners with meaningful Cognex RSU income often need quarterly estimated payments in addition to payroll withholding. The safe-harbor rule (110% of prior-year tax, for AGI over $150k) usually determines the minimum you need to send per quarter to avoid an underpayment penalty.
