What actually happens
An employee who lives in North Carolina and performs work in Virginia sits in two tax systems at once. The residence state claims the right to tax all of a resident's income wherever earned; the work state claims the right to tax income sourced within its borders. Absent an agreement, both claims stand, and the conflict is resolved after the fact through a credit on the resident return rather than up front in payroll.
When Virginia withholding starts
Virginia requires withholding from the first dollar of in-state compensation. There is no de minimis day count to shelter a short assignment. The Virginia employer withholding guide states no day or dollar de minimis safe harbor -- withhold on Virginia-source wages of nonresidents not covered by reciprocity. Virginia's separate individual FILING threshold (based on Virginia Adjusted Gross Income) is not a withholding safe harbor. Virginia does NOT accept federal Forms W-4/W-4P in place of the VA-4.
The trap is that thresholds are usually retroactive to the first day once crossed. An employee who spends 40 days in a 30-day-threshold state does not owe tax on 10 days; they owe it on all 40, and the employer is the one who failed to withhold.
Unemployment insurance goes to one state only
Income tax can be split between states. Unemployment insurance cannot. Under the localization test used by every state, an employee whose services are performed entirely in Virginia is covered by Virginia for unemployment purposes, and all wages are reported there — regardless of where they live, where you are headquartered, or which state's income tax you withhold. Virginia's 2026 taxable wage base is $8,000. The four-factor test in order.

Frequently asked
Do Virginia and North Carolina have a reciprocal tax agreement?
No. There is no reciprocal agreement between Virginia and North Carolina. Virginia taxes wages earned in the state by nonresidents, and North Carolina taxes the same wages as resident income while allowing a credit for tax paid to Virginia.
Which state's income tax should be withheld?
Virginia, as the state where the work is performed. North Carolina also taxes the income as a resident, but the employee claims a credit on the North Carolina return for tax paid to Virginia.
Which state gets the unemployment insurance wages?
Virginia. Unemployment coverage is never split between states for a single job. The localization test assigns the whole job to the state where services are performed, which here is Virginia, regardless of residence or where the employer is headquartered.
How many days can an employee work in Virginia before withholding starts?
There is no safe harbour. Virginia requires nonresident withholding from the first dollar of compensation earned in the state, so even a single day of in-state work creates an obligation in principle.
