Every business formation service wants to sell you a package, and most of those packages include a lot of things you don't actually need to legally start a business. Stripped down to the essentials, forming a business legally can cost surprisingly little, sometimes close to nothing beyond a state filing fee. The trick is knowing which parts are genuinely required, which parts are optional convenience, and which parts are upsells dressed up as necessities.
At the most basic level, operating a business legally means choosing a business structure, registering it if that structure requires registration, and handling any required licenses or tax registrations for your specific industry and location. A sole proprietorship, the simplest structure, often requires no formal state filing at all beyond a local business license or a "doing business as" (DBA) registration if you're operating under a name other than your own. An LLC, which most small business owners eventually want for the liability protection it offers, does require a state filing and a fee, but that fee is often the only mandatory cost involved.
Sole proprietorship: This is the cheapest option by a wide margin, since in most states there's no formal registration required to operate as a sole proprietor using your own legal name. If you want to operate under a business name, a DBA filing typically costs $10 to $100 depending on your state and county. The tradeoff is that a sole proprietorship offers no liability protection, meaning your personal assets aren't legally separated from business debts or lawsuits, which matters more as a business takes on real financial or legal risk.
LLC (do-it-yourself filing): Filing an LLC directly through your state's Secretary of State website, without using a paid formation service, typically costs between $50 and $500 depending on the state, with most states falling in the $100 to $200 range. This is the cheapest way to get liability protection while still being fully legitimate, since a DIY filing creates the exact same legal entity as one filed through an expensive service. The paperwork itself, an Articles of Organization form, is usually short and can genuinely be completed by most business owners without professional help for a single-owner, straightforward business.
LLC (using a paid formation service): Services like LegalZoom or ZenBusiness charge anywhere from $0 (plus state fees) for a basic package to $300 or more for packages bundling registered agent service, operating agreement templates, and expedited filing. These services save time and reduce the risk of a filing error, but they're not cheaper than filing directly with the state, since the state fee is identical either way. The value proposition is convenience and guidance, not cost savings.
The biggest legitimate cost-saving move is filing directly with your state yourself rather than paying a formation service, since the legal outcome is identical and the state filing fee is the only mandatory cost either way. Reading your state's specific instructions carefully and using the free templates many states provide for operating agreements (for LLCs) avoids paying for something you can do yourself with a bit of extra time.
Registered agent service is one area worth being careful about cutting costs entirely. Every LLC needs a registered agent, a person or service designated to receive legal documents, and while you can serve as your own registered agent for free in most states if you have a physical address in the state, doing so means your address may become part of the public record, and you need to be reliably available during business hours to receive legal notices. Paying $50 to $150 annually for a registered agent service is a reasonable cost for many business owners who value privacy or don't want to be tied to being available at a specific address during business hours.
Business licenses and permits are not optional costs to skip, even though they add to the total. Depending on your industry and location, you may need a general business license, a seller's permit for sales tax collection, or industry-specific permits, and operating without required licenses carries real legal and financial risk that outweighs whatever you'd save skipping them.
Start by deciding whether an LLC's liability protection is actually necessary for your situation, since a sole proprietorship remains genuinely free or near-free if your business carries minimal legal or financial risk and you're comfortable without the liability separation. If liability protection matters, which it does for most businesses beyond very low-risk side projects, move to filing an LLC directly through your state's Secretary of State website rather than a third-party service.
Next, decide on your registered agent approach: serve as your own agent if you're comfortable with the privacy tradeoff and reliable availability it requires, or budget for an affordable registered agent service if privacy or flexibility matters more to you. After the LLC is filed and approved, check your specific state and local requirements for business licenses, permits, and any industry-specific registrations, since skipping this step to save money creates real downstream risk rather than genuine savings.
Finally, use free or low-cost templates for your operating agreement (for an LLC) rather than paying a formation service for one, since most states and several nonprofit small business resources offer solid templates that cover the basics for a straightforward, single-owner business.
A freelance consultant operating under her own name with minimal liability exposure might reasonably start as a sole proprietor, spending close to nothing beyond a possible DBA filing if she wants a business name. As her client base grows and she starts signing contracts with more financial exposure, she files an LLC directly through her state's website for a $125 filing fee, serves as her own registered agent since she works from a stable home office, and uses a free operating agreement template from her state's small business resource center. Her total cost to legally form and protect her business: under $200, compared to $300 to $500 or more if she'd used a paid formation service with bundled add-ons she didn't need.
Paying for a formation service under the impression that it's cheaper or legally necessary is one of the most common misconceptions, when in reality the state filing fee is identical whether you file directly or through a paid service. Skipping required business licenses or permits to save money creates legal and financial risk that generally outweighs the savings, especially if a license violation is discovered later. And choosing to be your own registered agent without considering the privacy and availability tradeoffs can create problems if you move, travel frequently, or aren't consistently available at the listed address during business hours.
Is a sole proprietorship cheaper than an LLC? Yes, in most cases a sole proprietorship costs little to nothing to start, since it typically doesn't require a formal state filing. The tradeoff is no liability protection, which matters more as your financial or legal risk grows.
Are paid LLC formation services worth the extra cost? They offer convenience and reduce the risk of filing errors, but they don't reduce the actual state filing fee, which is the same whether you file directly or through a service. They're worth it primarily for time savings, not cost savings.
Can I be my own registered agent to save money? Yes, in most states, as long as you have a physical address in the state and can reliably be available during business hours to receive legal documents. The tradeoff is that your address becomes part of the public record and you take on the responsibility of not missing time-sensitive legal notices.
Do I need a business license even if I form an LLC cheaply? Yes. Forming an LLC and obtaining required business licenses are separate steps, and skipping licensing requirements to save money creates legal risk regardless of how your business is structured.
