Rhode Island's filing fee looks fairly ordinary. What makes it one of the pricier states to maintain a business in is a separate $400 minimum tax that every LLC owes every year, whether or not the business made any money. Here's what it takes to start a business in Rhode Island in 2026.
1. Which business structure fits you?
Before you file anything, it helps to know what you're actually choosing between.
- Sole proprietorship. No filing required to start, and you and the business are legally the same entity. Simple, but you're personally liable for whatever the business owes.
- Partnership. Two or more people running a business together, with the same liability exposure as a sole proprietorship, just split across partners.
- LLC. The most common structure for small businesses in Rhode Island. It separates your personal assets from the business's debts and lawsuits, though the $400 minimum tax applies regardless of structure for registered entities.
- Corporation, either S-corp or C-corp. More paperwork and more formality, usually worth it once you're bringing on investors or multiple shareholders.

LLCs and corporations register with the Rhode Island Department of State, Business Services Division, the agency that handles business filings statewide. Sole proprietorships and general partnerships don't register there.
2. Register your business
Forming an LLC
You form an LLC in Rhode Island by filing Articles of Organization with the Department of State. The filing fee is $150 in person or by mail, or $156 online, and standard processing takes 1 to 3 business days.
Every LLC needs a registered agent with a physical Rhode Island address, available during business hours. You can act as your own agent, or hire a commercial service.
Rhode Island doesn't require an operating agreement by law, but it's still worth writing one, particularly for multi-member LLCs, to spell out how decisions and profits get split.
Sole proprietorships and DBAs
Sole proprietorships don't file Articles of Organization and, notably, aren't subject to the $400 minimum business tax the way registered entities are. If you're operating under a trade name, you'll register it with the city or town clerk where your business is located.
3. Get an EIN
An Employer Identification Number is free straight from the IRS and takes about 15 minutes online. You'll need one to open a business bank account, hire anyone, or file most business tax forms, even if you're a single-member LLC with no employees.
4. Check licenses and permits
Rhode Island doesn't issue a single general statewide business license either. What you need depends on your industry and city: professional licensing for regulated fields, local permits in some cities, and a sales tax permit from the Division of Taxation if you sell taxable goods or services. Our guides on professional licensing by industry and zoning laws for home businesses cover more of this.
5. Understand Rhode Island taxes
Rhode Island's personal income tax is progressive, from 3.75% up to 5.99% at the top. On top of that, every LLC, corporation, and limited partnership registered in Rhode Island owes a $400 minimum business tax to the Division of Taxation every year, regardless of income or activity, and it's not prorated even if you formed partway through the year.
Sales tax is a flat 7% statewide, and Rhode Island doesn't allow any local add-ons, so the rate is the same everywhere.
6. Stay compliant
Every Rhode Island LLC files an Annual Report with the Department of State, due between September 1 and November 1 each year. The fee is $50 (plus a small online convenience fee). Separately, the $400 minimum business tax return is filed with the Division of Taxation. A $25 late fee applies to the annual report after November 1, with a short grace period into December.
