BPOL Licenses for Dental Practices in Virginia
How Virginia’s BPOL business license tax works for dentists in Fairfax, Arlington and Loudoun: thresholds, rates, new-practice estimates and March 1 deadlines.
Key Takeaways
- BPOL is a local license tax on gross receipts, not profit; every Northern Virginia county, town and independent city sets its own.
- Fairfax and Arlington charge flat fees up to $100,000 of receipts, then a rate; Loudoun charges $30 up to $200,000, then a rate.
- Published professional rates: Fairfax $0.31, Loudoun $0.33 and Arlington $0.36 per $100 of gross receipts; confirm your classification.
- New practices register within 75 days of starting in Fairfax and Arlington and within 30 days in Loudoun, using estimated receipts.
- Annual renewals are due March 1 (or the next business day), with late penalties.
- Nearby localities differ widely: Alexandria charges $0.58 per $100, while Prince William County taxes only receipts of $500,000 or more.
Virginia lets its counties, cities and towns levy a Business, Professional and Occupational License (BPOL) tax. For a dental practice it works like a small percentage of gross receipts, paid annually to the locality where the practice operates. The amounts are modest compared with income tax, but missing registration or a renewal deadline brings penalties, and new owners often do not know it exists. This guide explains how BPOL works for dentists in Northern Virginia.
What BPOL Is (and Is Not)
- It is a local tax. The state sets the framework and caps in Va. Code § 58.1-3706; each locality sets its own rates and rules.
- It is based on gross receipts, not net income. A practice that loses money in year one still owes BPOL on what it collected.
- It is separate from business personal property tax, which applies to equipment and furniture.
- It applies where the practice operates. A practice inside an incorporated town or an independent city deals with that town or city.
The state code caps the rate for financial, real estate and professional services at $0.58 per $100 of gross receipts, and sets the receipts threshold below which localities with more than 50,000 people may not apply the rate at $100,000.
Northern Virginia Rates and Thresholds
| Locality | Flat fee tiers | Rate above threshold (professional) | New business registration |
|---|---|---|---|
| Fairfax County | $0 up to $10,000; $30 for $10,001–$50,000; $50 for $50,001–$100,000 | $0.31 per $100 (Professional Occupations) | Within 75 days of starting |
| Arlington County | $0 up to $10,000; $30 for $10,001–$50,000; $50 for $50,001–$100,000 | $0.36 per $100 (County Code lists dentists among professional occupations) | Within 75 days of starting |
| Loudoun County | $30 up to $200,000 | $0.33 per $100 (Professional Services) | Within 30 days of starting |
Figures are from each county’s published BPOL pages and code at the time of writing. Rates can change with each budget, and the county decides your classification, so confirm both before you file. The Fairfax rate schedule does not name dentists specifically; dental practices generally fall under professional occupations, but confirm with the Department of Tax Administration.
What It Costs in Practice
Illustrative annual BPOL on a few collection levels, using the published professional rates:
| Gross receipts | Fairfax ($0.31) | Loudoun ($0.33) | Arlington ($0.36) |
|---|---|---|---|
| $600,000 | $1,860 | $1,980 | $2,160 |
| $1,200,000 | $3,720 | $3,960 | $4,320 |
| $2,000,000 | $6,200 | $6,600 | $7,200 |
Above the threshold, the rate is generally applied to the full gross receipts figure, not just the amount over the threshold. Check how your locality calculates it.
How It Works for a New Practice
A brand-new practice has no prior-year receipts, so Fairfax and Arlington require an estimate. Per the Fairfax County BPOL guidance, you estimate gross receipts for the first partial year and the first full calendar year, and the county adjusts to actual receipts afterward, refunding or crediting an overestimate. From the third year on, the tax is based on the prior year’s actual receipts. Arlington describes the same estimate-and-true-up approach.
Loudoun charges a $30 fee in the first year, then bases the tax on the prior year’s gross receipts. Registration requires your State Corporation Commission entity registration and an EIN first. See Loudoun’s business license page.
What to have ready
- Federal EIN and entity documents (professional corporation or PLLC).
- NAICS code (dentists’ offices are commonly 621210; confirm with the county).
- Business location and mailing address, start date, owner and trade names.
- Estimated first-year gross receipts.
A first-year example
Suppose you open a practice in Fairfax County in July. When you register, you estimate receipts for the partial first year, say $300,000, and the county computes the license tax on that estimate: $300,000 / $100 × $0.31 = $930. When you renew the following March, you report actual receipts for the first year so the county can adjust, and you provide an estimate for the first full calendar year, say $1,000,000, or $3,100 in tax. The year after that, the tax is based on the prior year’s actual receipts.
Because the true-up can produce a refund or a bill, keep your estimate realistic. A practice that underestimates heavily in a strong ramp year can face a larger payment than expected at renewal. Your business plan projections are a sensible basis for the estimate.
What counts as gross receipts
For BPOL purposes, gross receipts generally means the total amount received by the business from the licensed activity in the locality. For a dental practice that is mainly patient and insurance payments for services. Ask your CPA how to treat items such as refunds, interest income or receipts from another location, and keep the supporting reports from your practice management system with your filing.
Annual Deadlines
- Fairfax, Arlington and Loudoun renewals are due March 1, moved to the next business day if it falls on a weekend or holiday.
- Fairfax applies a 10% penalty to late renewals and late new-business registrations.
- Business personal property returns for equipment are a separate filing: due May 1 in Fairfax and on the same March 1 date as BPOL in Loudoun.
Towns, Cities and Multiple Locations
Because BPOL is local, the address on your lease decides who you file with. Loudoun County’s own guidance says businesses in incorporated towns should contact the town for a business license. In Fairfax County, towns such as Herndon and Vienna can have their own licensing and permit requirements (the county does not issue Certificates of Occupancy in Vienna, for example), so a practice in a town should check with the town first. Alexandria and Manassas are independent cities and run their own BPOL programs with their own rates.
If you open a second location in a different jurisdiction, each locality generally taxes the gross receipts attributable to the office in its jurisdiction. That can require allocating receipts between offices. Keep production and collections tracked by location in your practice management system from the start, so the allocation is easy to support.
Associates who work as independent contractors may have their own BPOL obligations, separate from the practice. See W-2 vs. 1099 dental associates.
Alexandria, Prince William and Manassas
Practices just outside the three big counties face noticeably different numbers, which can matter when you compare sites:
| Locality | Professional rate | Threshold or minimum | Note |
|---|---|---|---|
| City of Alexandria | $0.58 per $100 | $50 flat tax for receipts of $10,000 to $99,999; rate applies at $100,000 and above | The state maximum rate for professional services |
| Prince William County | $0.33 per $100 | No tax below $500,000 of gross receipts | Businesses at or above $500,000 must obtain a license |
| City of Manassas | $0.33 per $100 on the city’s 2024 application | Check the current application | Independent city; separate from Prince William County |
The same practice with $1.2 million of receipts would owe roughly $6,960 in Alexandria at $0.58 and $3,960 in Prince William County at $0.33, compared with $3,720 in Fairfax County. These figures come from each locality’s published rate pages and forms; confirm them with the city’s or county’s commissioner of the revenue or finance office before you file.
What Is Excluded From Gross Receipts
Virginia’s BPOL statute, Va. Code § 58.1-3732, lists items that are not gross receipts. The ones most relevant to a dental practice include:
- Refunds, returns and allowances given to patients.
- Loan proceeds the practice receives as a borrower.
- Interest on business bank accounts and income from investing the practice’s own funds, when unrelated to the licensed activity.
- Proceeds from the occasional sale of assets that are not inventory, such as old equipment.
- Discounts and rebates on the practice’s own purchases.
Patient and insurance payments for dental services are the core of gross receipts. Keep your practice management collection reports and bank records together with each filing so you can support the figure if the locality audits it.
Penalties, Interest and Appeals
Under Va. Code § 58.1-3703.1, a locality may impose a 10% penalty for failing to file or pay by the due date, and a separate 10% penalty if an assessment remains unpaid 30 days later. Interest runs from the due date until payment. The penalty, but not the interest, can be waived if the failure was not your fault and you can show you acted responsibly.
If you disagree with an assessment, you can appeal to the local assessor within one year after the last day of the tax year assessed, and then to the Virginia Tax Commissioner within 90 days of the local decision. Collection is generally suspended while an appeal is pending, but interest continues to accrue.
BPOL vs. Business Personal Property Tax
| BPOL license tax | Business personal property tax | |
|---|---|---|
| What is taxed | Gross receipts | Assessed value of equipment, furniture and fixtures |
| Fairfax County | $0.31 per $100 of receipts (professional), due March 1 | $4.57 per $100 of assessed value, return due May 1 |
| Loudoun County | $0.33 per $100 above $200,000, due March 1 | $4.15 per $100 of assessed value, return due March 1 |
| Owed in a loss year? | Yes, on receipts | Yes, on assessed equipment value |
Both belong in your budget from the first year. A new practice with $300,000 of new equipment can owe more in personal property tax than in BPOL, even though BPOL gets more attention. Our equipment budget guide covers the property tax side.
Common BPOL Mistakes
- Not registering at all in the first year because no one mentioned it.
- Registering with the county when the practice is inside a town or independent city.
- Underestimating first-year receipts, then owing a larger true-up.
- Reporting net income or production instead of gross receipts.
- Missing March 1 because it falls in the middle of tax season.
How BPOL Fits Your Overall Tax Picture
BPOL is a deductible business expense for federal income tax purposes, and it belongs in your startup projections and annual budget. It is one of several local filings that a dental CPA should calendar alongside payroll taxes and income tax estimates. See our tax planning guide, our permits guide, and our year-end checklist.
If you buy an existing practice, confirm that the seller’s BPOL and business personal property filings are current, and register your own entity with the locality as a new business. The seller’s license does not transfer to you.
Registering a New Practice, Step by Step
- Form the professional corporation or PLLC with the State Corporation Commission and get an EIN.
- Confirm whether the office address is in a county, town or independent city.
- Register with that locality’s BPOL office within its deadline (75 days in Fairfax and Arlington, 30 days in Loudoun), using a realistic receipts estimate where required.
- File the business personal property return for equipment by the locality’s deadline.
- Calendar the March 1 renewal and the true-up for your first full year.
Building BPOL Into Your Monthly Budget
Because BPOL is paid once a year, it is easy to forget until March. A simple fix is to accrue it monthly. A Fairfax practice expecting $1.2 million of collections would owe about $3,720 at $0.31 per $100, or about $310 a month. Set that aside with the same discipline as payroll taxes, and add the business personal property tax on top. If you renew in a year of fast growth, remember that Fairfax and Arlington may bill a true-up when they compare your estimate with actual receipts.

BPOL is based on gross receipts, which for a dental practice generally means amounts actually received, not scheduled or billed production. Ask your CPA how to report for your accounting method.
Only once gross receipts reach the county’s threshold. Prince William County’s 2026 license application shows no tax below $500,000 of gross receipts and $0.33 per $100 for professional occupations at or above it. Practices inside the City of Manassas file with the city instead.
Virginia law lets localities charge a 10% penalty for late filing or payment, plus a separate 10% penalty if an assessment is unpaid after 30 days, and interest from the due date. Penalties can be waived for reasonable cause; interest cannot.
Generally no. Va. Code § 58.1-3732 excludes interest on business bank accounts and income from investing the business’s own funds when unrelated to the licensed activity. Refunds to patients and loan proceeds are also excluded.
