Form an LLC almost anywhere and the profits flow straight through to your personal return. Form one in Washington, D.C., and the District may tax the business first. D.C. is one of the few places that taxes many unincorporated businesses at the entity level, so the structure you choose here shapes what the company owes from its first profitable year. That is the kind of detail a formation service will not flag and a general practitioner may miss. Stephen Thienel is a business attorney who works with District companies on formation, contracts, deals, and succession, and because he also holds an LL.M. in Taxation, he handles the business, tax, and estate questions that choice raises himself, instead of sending you to a second firm for the tax half of the answer.
What makes doing business in Washington, D.C. different?
No single industry defines the District. The federal government and the contractors, consultants, and law firms that orbit it set the tone downtown, but the city also runs on the trade associations and nonprofits clustered around K Street, a growing startup and tech base in neighborhoods like NoMa, and a hospitality scene that fills the Wharf, Capitol Hill, and Georgetown. A company’s legal needs track its corner of that economy. What a federal subcontractor worries about in its contracts and clearances looks nothing like what a restaurant group or a membership organization deals with, even a few blocks apart.
The District also backs its local companies in ways worth knowing early. Through the Department of Small and Local Business Development, a business headquartered in D.C. can become a Certified Business Enterprise and earn a bidding preference on city contracts. For a company that sells to the District itself, that status can be worth as much as a strong proposal.
Tax treatment is where the District departs most sharply from its neighbors. Because D.C. can tax an LLC or partnership at the entity level under its unincorporated business franchise tax, subject only to narrow exemptions, the entity you choose and the way you document its income carry weight here that they would not across the river. Sorting that out at formation costs far less than restructuring after the first return.
Court is simpler in one respect. The District runs a single trial court rather than the circuit-and-district split used in Maryland and Virginia: the Superior Court of the District of Columbia hears civil business cases, sends smaller matters to its Small Claims and Conciliation Branch, and sees its decisions appealed to the D.C. Court of Appeals. Ongoing compliance is straightforward too. A D.C. company registers with the Department of Licensing and Consumer Protection, keeps a registered agent in the District, and files a biennial report every two years to hold its good standing. Stephen is admitted in D.C. and can take a matter into the Superior Court when it cannot be settled any other way.
What business services does Thienel Law offer in Washington, D.C.?
Most of what a District company needs from a business lawyer falls into a handful of areas, and Stephen takes them on directly rather than routing the work to associates:
Business formation and entity selection
Weighed against the District’s franchise tax so you start as the right entity rather than amending later.
Learn moreContract drafting and review
The agreements a company runs on, from vendor and client contracts to NDAs.
Learn moreOperating and partnership agreements
Fix ownership, control, and what happens when circumstances change.
Learn moreBusiness purchases and sales
On either side of a buy, sale, or merger.
Learn moreBuy-sell and succession agreements
Hold ownership steady as partners arrive, leave, or retire.
Learn moreCommercial lease review
You commit to space downtown, on Capitol Hill, or anywhere in the District.
Learn moreBusiness, tax, and estate questions rarely stay in separate lanes, so many District owners end up working with Stephen across several of these as the company grows.
Why do Washington, D.C. business owners work with Stephen Thienel?
The draw is reach across the whole region. Stephen is licensed in the District, Maryland, and Virginia and practices business, tax, and estate law in each, so a D.C. company that hires in Maryland, opens an office in Virginia, or sells throughout the area keeps one lawyer instead of assembling three. His LL.M. in Taxation is what makes that practical: the franchise-tax question, a deal’s tax consequences, and an owner’s estate plan all land with the same person, and you are billed once for the answer.
That range rests on an unusual foundation. Stephen earned his J.D. at the University of Maryland and an LL.M. in Taxation at the University of Baltimore, and before law he took an M.A. in economics at Virginia Tech under Nobel laureate James Buchanan. He tends to read a transaction the way the owner across the table reads it, not only the way a lawyer would.
The office sits in Alexandria, a short drive across the Potomac, and the practice is fully remote, built to reach the District without costing you a day. Secure document sharing, electronic signatures, and video meetings carry the work, and Stephen appears in the District’s courts when a matter calls for it. You deal with him directly, on terms agreed before any work begins.
Companies that want a lawyer on call without a full-time hire can also bring Stephen on as fractional general counsel for a set monthly fee.

Frequently asked questions
Should I form an LLC or a corporation in Washington, D.C.?
It turns on how you want to be taxed, who will own the company, and whether you plan to raise outside money. That choice carries extra weight in the District, where an entity-level franchise tax can reach businesses that would be pure pass-through in Maryland or Virginia. Because Stephen holds an LL.M. in Taxation, he can work through that tax question with you instead of sending you elsewhere for the answer.
Does my D.C. LLC have to pay the District's franchise tax?
Possibly. D.C. applies a franchise tax to many unincorporated businesses, including a range of LLCs and partnerships, for carrying on a trade or business in the District, though narrow exemptions exist, such as one for businesses whose income comes mostly from the owners' own personal services. Whether yours owes it depends on how it earns its income, which is worth settling before you pick an entity rather than after.
What do I have to file to keep my D.C. business in good standing?
A biennial report. D.C. companies register with the Department of Licensing and Consumer Protection, keep a registered agent in the District, and file that report every two years to stay in good standing. Let it lapse and the company can lose its good standing, which surfaces the moment a bank, a buyer, or a counterparty runs a check.
Does Thienel Law have an office in Washington, D.C.?
No. The firm works from Alexandria, Virginia, minutes across the Potomac, and Stephen serves District companies through a fully remote practice: secure online meetings, document sharing, and electronic signatures. He appears in the District's courts when a matter requires it.
Do I need a separate lawyer for the tax side of a business decision?
Usually not. Stephen holds an LL.M. in Taxation and practices business, tax, and estate law, so he can take on the tax and succession side of a business decision himself rather than referring you to another firm.
