Doing business in Sterling
Sterling is not an incorporated town. It is a census designated place in eastern Loudoun County, so every local business filing goes to the county: the business license, the business personal property return and the tax bills that follow.
The Route 28 corridor on Sterling's west side is lined with business and industrial parks, home to contractors, distributors, equipment and auto businesses and the companies that supply them. The corridor keeps changing: in May 2026, plans were reported for three data centers along Route 28 in Sterling, replacing warehouses, offices and a hotel.
Sterling also has its own Silver Line stop, Loudoun Gateway, opened in November 2022, and a busy mix of restaurants, shops and service businesses along Route 7 and near Dulles Town Center. For most of these owners the hard part is not the tax rules. It is time, because jobs, crews and inventory leave little room to reconcile accounts every month.

Learn moreLoudoun County business taxes in Sterling
Since Sterling is unincorporated, you deal with one local tax office, the Loudoun County Commissioner of the Revenue. Its rules differ from Fairfax County's, which matters if you also work across the county line.
| Tax | What to know | Due |
|---|---|---|
| Business license (BPOL) | A flat fee for smaller businesses. Above the County threshold, a rate per $100 of receipts that depends on your business type. Very small home businesses still file but may pay no fee. | March 1. New businesses register within 30 days |
| Contractor details | Contractors provide their Virginia contractor license number, or an affidavit, and proof of workers' compensation coverage with the license return. | With the license |
| Wholesale businesses | Taxed on purchases rather than gross receipts. | March 1 |
| Business personal property | A return listing the equipment, tools, furniture and computers your business owns. A 30 day extension is available on request; late filing costs 10%. | March 1 |
Good to know: Contractors can owe license tax in more than one place. A contractor without an office in another Virginia locality generally needs that locality's license once its work there passes $25,000 in a year. We track receipts by job location so you can see it coming.
Rates and dates change. Confirm current figures with the locality before filing, or let us handle it.
