Herndon, VA · Local advisory
Herndon combines a historic downtown with office parks full of technology companies and federal contractors near Dulles Airport and the Silver Line. Our advisors serve Herndon businesses and their owners.
What we handle
The Town of Herndon levies its own business license tax, and Fairfax County taxes business personal property. Technology and contracting companies here need accurate classification, DCAA-ready accounting and planning for research credits and section 174A expensing.
Herndon owners and employees often hold equity, work across state lines or have family and assets abroad. We plan for stock compensation, foreign reporting and Virginia pass-through entity tax, and represent clients before the IRS.
