Editorial Team
Introduction
Forming an LLC in Washington, D.C. comes with its own set of rules, fees, and filing requirements. This FAQ covers the questions entrepreneurs ask most often — from the $99 state filing fee and registration steps to business licenses, taxes, and staying in good standing.
What you need to know about forming a D.C. LLC
Washington, D.C. is not a state, but it has its own business formation process administered by the District of Columbia Department of Licensing and Consumer Protection (DLCP). To form an LLC here, you file Articles of Organization with the DLCP Corporations Division, pay the required fee, and meet a handful of ongoing compliance requirements. The questions below walk through each part of that process — what it costs, how long it takes, what licenses you need, and what you have to do each year to keep your LLC in good standing.
Washington, D.C. LLC frequently asked questions
The standard filing fee to form a Washington, D.C. LLC is $99, paid to the DLCP Corporations Division when you file your Articles of Organization. That's the base cost to get your LLC on record with the District. If you file in person, the DLCP requires an additional $50 expedited service fee on top of the $99.
After formation, plan for additional costs: a Basic Business License, DC tax registration, and a registered agent if you use a third-party service. These vary depending on your business type and structure.
Standard processing through the DLCP typically takes up to a week after you file your Articles of Organization. Online filings through the District's CorpOnline system tend to move faster than mail filings. If you file in person, the DLCP offers one-day service for an additional $50 expedited fee.
Processing times can shift depending on filing volume at the DLCP. Online filing is the most reliable way to track your submission and get a faster turnaround.
To form a Washington, D.C. LLC, you file Articles of Organization (Form DLC-1) with the DLCP Corporations Division. You can file online through the District's CorpOnline system, by mail to PO Box 92300, Washington, DC 20090, or in person at 1100 4th Street SW, Second Floor, Washington, DC 20024.
Before filing, check that your chosen business name is available using the CorpOnline name search. Your LLC name must include "limited liability company" or an accepted abbreviation like "LLC" or "L.L.C." and must be distinguishable from names already on file with the District.
The D.C. LLC registration fee is $99 for filing Articles of Organization with the DLCP Corporations Division. This is the standard fee for forming a domestic LLC in the District. An additional $50 expedited service fee applies if you file in person and want same-day processing.
You search for available business names in Washington, D.C. through the DLCP's CorpOnline system. If your search returns no results, the name is likely available. Your LLC name must be distinguishable from all existing entities on file with the District and must include "LLC," "L.L.C.," or "limited liability company."
Running the name search before you file saves time. A name that looks unique can still be rejected if it's too similar to an existing entity — the DLCP applies a distinguishability standard, not just an exact-match test.
It depends. A multi-member LLC or any LLC with employees must get an EIN from the IRS. A single-member LLC with no employees can use the owner's Social Security number instead, but an EIN keeps your personal number off business documents and is required before you can register for DC taxes using the FR-500 form.
The IRS issues EINs at no cost. You can apply online at irs.gov, by fax, or by mail using Form SS-4. Most online applications are processed immediately.
Yes. Washington, D.C. requires all new businesses to register with the DC Office of Tax and Revenue (OTR) by filing Form FR-500, the New Business Registration form. You'll need your EIN or Social Security number, your legal business structure, and your business address to complete the registration.
D.C. LLCs that are not taxed as corporations are generally subject to the Unincorporated Business Franchise Tax for the privilege of doing business in the District. A tax professional can help you figure out which DC tax accounts apply to your specific business.
Yes. Virtually all businesses operating in Washington, D.C. need a Basic Business License (BBL) issued by the DLCP, in addition to forming the LLC itself. The BBL covers specific business activity categories — things like retail, professional services, and home-based businesses — and is required before you begin operations.
If your LLC operates from a physical location, you may also need a Certificate of Occupancy. Home-based businesses typically need both a Home Occupation Permit and the applicable BBL category. The general sequence is: form the LLC, get an EIN, register for DC taxes, confirm zoning, then apply for your license.
No, D.C. law does not require you to file an operating agreement with the government. But having a written operating agreement is strongly recommended. Without one, your LLC falls back on D.C.'s default statutory rules, which may not reflect how you actually want to run the business.
A good operating agreement covers ownership percentages, capital contributions, profit and loss allocation, and whether the LLC is member-managed or manager-managed. In a member-managed LLC, all members share day-to-day authority. In a manager-managed LLC, that authority is delegated to one or more designated managers.
Washington, D.C. LLCs must file a biennial report (Form B25) with the DLCP every 2 years to stay in good standing. The first biennial report is due by April 1 of the first calendar year after your LLC is registered. After that, it's due by April 1 every other year.
Your LLC must also maintain a registered agent with a physical address in the District at all times. Not filing the biennial report can cause your LLC to fall out of good standing and may lead to administrative dissolution — meaning the District can revoke your LLC's authority to do business.
It depends on your goals, but for many entrepreneurs, an LLC offers a practical balance of liability protection and administrative simplicity. The 3 main for-profit entity types in D.C. are LLCs, S Corporations, and C Corporations. LLCs avoid the double taxation that C Corporations face and have fewer formality requirements than either corporation type.
The right structure depends on how you plan to raise money, pay yourself, and handle taxes. A tax professional can help you figure out which structure fits your situation before you file.
The mistakes that come up most often are: skipping the name availability search before filing, not registering for DC taxes with the OTR after formation, and starting operations before getting a Basic Business License. Each of these can create delays, fines, or gaps in your legal standing.
Another one that catches people off guard: missing the biennial report deadline. D.C. requires the report every 2 years, and not filing it can put your LLC out of good standing — which affects your ability to enter contracts, open accounts, and operate legally in the District.
