Ohio LLC vs. sole proprietorship: which one fits your business?
An Ohio sole proprietorship costs nothing to start, but you are personally responsible for every business debt. An Ohio LLC costs $99 to form, separates business debts from you by statute, and with one owner is taxed the same way by default.
What is the difference between an Ohio LLC and a sole proprietorship?
An Ohio sole proprietorship is not a separate legal thing. It is you, doing business. There is nothing to file with the Ohio Secretary of State to start one, and it ends when you stop. The business's debts are your debts, and a lawsuit against the business is a lawsuit against you.
An Ohio LLC is a separate legal entity. It comes into existence when the Secretary of State files its Articles of Organization (Form 610). It owns its own property, signs its own contracts, and can sue and be sued in its own name. Chapter 1706 of the Ohio Revised Code governs it, including the rule that a member is not liable for the LLC's debts solely because they are a member (ORC 1706.26).
The daily work can look identical. A painter, a bookkeeper, or an online seller does the same jobs either way. The differences show up when something goes wrong, at tax time, and on the public record.
Ohio LLC vs. sole proprietorship at a glance
| Question | Sole proprietorship | Ohio LLC |
|---|---|---|
| State filing to start | None | Articles of Organization, Form 610 |
| State fee to start | $0 ($39 if you register a trade name) | $99 |
| Annual state report or fee | None | None; Ohio LLCs do not file annual reports |
| Personal liability for business debts | Yes, all of them | Not solely because you are a member (ORC 1706.26) |
| Default federal income tax | Profit on your personal return | One member: disregarded, same as a sole proprietor. Two or more: partnership |
| Self-employment tax | 15.3% on net earnings of $400 or more | Same by default; an S corp election changes how owner pay is taxed |
| Statutory agent required | No | Yes, at all times (ORC 1706.09(A)) |
| Business name | Your legal name, unless you register a trade name or report a fictitious name | The LLC's name; a different brand name needs its own filing |
| Ownership | One person only | One or more members, set out in an operating agreement |
| Bank account | Can be in your own name | In the LLC's name, kept separate from yours |
If you take one line from the table, take this one: by default, the IRS taxes a single-member LLC the same way it taxes a sole proprietor. Forming an LLC changes your legal exposure and your paperwork far more than it changes your tax bill.
Does an Ohio LLC protect personal assets better than a sole proprietorship?
As a sole proprietor, a judgment against your business can be collected from your personal bank account, your vehicle, and other things you own. There is no line between the two, because there is only one of you.
An Ohio LLC draws that line. ORC 1706.26 says a member is not liable, solely by reason of being a member, for a debt, obligation, or liability of the LLC, whether it arises in contract, tort, or otherwise. The same section says a failure to observe formalities is not a ground for holding members liable for the LLC's debts. A skipped meeting or missing minutes is not, on its own, a reason to reach the members.
The protection has limits you should understand before you rely on it:
- A personal guarantee is a personal promise. If you guarantee a loan, lease, or credit line, you are liable on it, LLC or not. Lenders and landlords often ask new LLC owners for one.
- The statute protects you from liability that comes from being a member. It does not erase responsibility for your own conduct. How that applies to a specific claim is a question for your attorney.
- Mixing money weakens the separation in practice. Keep the LLC's money in the LLC's account and pay yourself from it in a way you can trace.
- Insurance still does its own job. The LLC keeps business claims away from personal assets; liability insurance pays the claims.
For a business with customers on site, employees, vehicles, or contracts with real money at stake, this difference is usually the main reason owners choose an LLC.
What does each one cost to start and keep in Ohio?
A sole proprietorship has no formation cost in Ohio. If you operate under a name other than your own legal name, you either register a trade name or report a fictitious name with the Secretary of State, and each costs $39 under ORC 1329.01. A trade name registration lasts five years and can be renewed within the six months before it expires (ORC 1329.04).
An Ohio LLC costs $99 to form under ORC 111.16(F). Ohio charges no annual report fee to keep an LLC on the record. The recurring cost most owners have is a statutory agent. You can serve as your own agent if you live in Ohio and are home during business hours, or you can use a service. Ours is $49 per business per year.
| Cost item | Sole proprietorship | Ohio LLC |
|---|---|---|
| Start-up state filing | $0 | $99 |
| Trade name or fictitious name | $39 if you use one | $39 if the brand differs from the LLC name |
| Trade name renewal, every five years | $25 | $25 |
| Annual state report | None | None |
| Statutory agent | Not required | $0 if you serve yourself, or $49 per year with us |
| Agent change later (Form 521) | Not applicable | $25 |
Neither choice changes your city income tax, sales tax, or license costs. Those depend on what you sell and where you work, not on the entity type.
How are an Ohio LLC and a sole proprietorship taxed?
Federal income and self-employment tax
A sole proprietor reports business profit on their personal federal return and pays self-employment tax of 15.3% (12.4% for Social Security and 2.9% for Medicare) once net earnings reach $400. The IRS treats an LLC with one member as disregarded from its owner for income tax, so the owner reports the same way. An LLC with two or more members is classified as a partnership by default, and each member's share passes through to their own return.
An LLC can choose a different classification. Form 8832 elects corporate treatment, and Form 2553 elects S corporation status. A sole proprietor cannot make either election without first forming an entity. The trade-offs are covered in Ohio LLC vs. S corp.
Ohio income tax
Ohio taxes pass-through business income on the owner's personal Ohio return in both cases. ORC 5747.01(A)(28) lets an individual deduct up to $250,000 of business income ($125,000 for each spouse filing separately), and ORC 5747.02(A)(4) taxes business income above that at a flat 3%. A sole proprietor and a single-member LLC owner use the same deduction and the same rate.
Taxes that follow the activity, not the entity
The Commercial Activity Tax applies once Ohio taxable gross receipts exceed $6 million a year. Sales tax applies to taxable sales. Many Ohio cities tax net profits. None of these turn on whether you are a sole proprietor or an LLC. Our overview of Ohio LLC taxes walks through each one and links to the detailed pages.
Paperwork and ongoing requirements compared
A sole proprietor's paperwork is light: a trade name or fictitious name filing if you use one, the tax registrations that apply to your work, and your personal tax return.
An Ohio LLC adds a few items, none of them heavy:
- Form 610 at formation, naming a statutory agent who signs an acceptance of the appointment.
- A written operating agreement. Ohio does not file it, but it says who owns what and what happens if a member leaves.
- A statutory agent on record at all times, and a Form 521 Statutory Agent Update ($25) if the agent or the agent's address changes.
- A separate bank account and books, so the LLC's money is visibly the LLC's.
- No annual report. Ohio LLCs do not file one.
If an LLC fails to keep an agent, the Secretary of State sends notice and cancels the articles if the problem is not fixed within 30 days (ORC 1706.09(L)). That is the ongoing requirement Ohio enforces with cancellation, and it is why most owners keep a dependable Ohio statutory agent service on the record. A sole proprietor has no equivalent duty, because there is no entity to cancel.
Does an Ohio sole proprietor need a DBA?
Yes, if the sole proprietor does business under any name other than their own legal name. Jane Smith working as "Jane Smith" files nothing. Jane Smith working as "Smith Exterior Painting" needs a filing. Ohio offers two, both under ORC 1329.01 and both $39:
- Trade name registration, for a name you claim exclusive rights to. It lasts five years and can be renewed.
- Fictitious name report, for a name you use without registering it as a trade name. The report is due within 30 days after you first use the name.
The filing matters beyond the paperwork. Under ORC 1329.10(B), a person doing business under a trade name or fictitious name cannot start or maintain a lawsuit until they have complied with ORC 1329.01. Filing cures it, and the suit can then cover earlier contracts, but that is a delay you don't want when a customer won't pay.
A DBA does not create an entity or protect personal assets. It only puts a business name on the record. An LLC that markets under a different name files the same kind of registration. Our Ohio trade name and DBA filing service handles either case, and Ohio DBA vs. LLC compares the two directly.
When does a sole proprietorship still make sense, and when should you switch?
A sole proprietorship is a reasonable starting point when:
- You are testing an idea with little money and no employees.
- The work carries little risk of injury or property damage claims.
- You have no leases, loans, or large contracts in the business's name.
Owners usually move to an LLC when:
- Customers, employees, or vehicles create real exposure to claims.
- You start signing leases, vendor contracts, or financing for the business.
- A second owner joins. Under ORC 1776.22(A), two or more people carrying on a business as co-owners for profit form a partnership whether or not they intend to. An LLC with an operating agreement sets the terms on purpose instead.
- You want your home address off the public record. The LLC's record shows its statutory agent's address, which can be a service office instead of your house.
- Your accountant recommends an S corp election, which requires an entity.
Whether the liability protection or a tax election is worth it in your situation is a judgment call. Talk to your attorney or accountant before you decide.
How to move a sole proprietorship into an Ohio LLC
Ohio has no form that converts a sole proprietorship into an LLC, because the sole proprietorship was never an entity. You form a new LLC and move the business into it.
- Pick the LLC name and check it on Ohio Business Central.
- Appoint a statutory agent and file Form 610 ($99). The steps are in how to start an LLC in Ohio.
- Decide on the EIN with your accountant. The IRS says a single-member LLC can keep using the sole proprietor's EIN only if it has no employees, owes no excise tax, and is not taxed as a corporation.
- Open a bank account in the LLC's name.
- Move tax accounts, licenses, insurance, and contracts to the LLC's name.
- Decide what to do with any trade name you registered as a sole proprietor, since it was registered to you, not the LLC.

More questions about Ohio LLCs vs. sole proprietorships
Is an LLC or a sole proprietorship cheaper to run in Ohio?
A sole proprietorship is cheaper, because Ohio charges nothing to start one and nothing yearly. An LLC costs $99 to form and has no annual report fee, so its main recurring cost is a statutory agent if you don't serve yourself. Trade name fees are the same for both: $39 to register and $25 to renew every five years.
Do Ohio sole proprietors and LLC owners pay the same city income tax?
Generally yes, because Ohio municipal income tax reaches business net profits whether a sole proprietor or an LLC earns them. Cities levy the tax under ORC Chapter 718, and forming an LLC does not change which cities you work in. City rules on pass-through entities differ, so check the filing rules in each city where you do business.
Can an Ohio sole proprietor be sued personally for business debts?
Yes, because a sole proprietorship has no separate legal existence from its owner. A creditor or injured customer who wins a judgment can collect from the owner's personal assets. An Ohio LLC member is not liable for the LLC's debts solely by being a member under ORC 1706.26, though personal guarantees and claims about your own conduct are separate questions for an attorney.
Does an Ohio sole proprietorship need a statutory agent?
No, a sole proprietorship does not need a statutory agent, because it is not a registered entity. Lawsuits against a sole proprietor are served on the owner personally. Once you form an LLC, ORC 1706.09 requires it to keep an Ohio statutory agent on record at all times, starting with the agent named on Form 610.
Do I need a new EIN when my Ohio sole proprietorship becomes a single-member LLC?
Not always; the IRS lets a single-member LLC keep the sole proprietor's EIN in some cases. That works only if the LLC has no employees, owes no excise tax, and is not taxed as a corporation or S corporation. If any of those apply, the LLC needs its own EIN. Your accountant can confirm which applies before you open the LLC's bank account.
Can two people run a business together as a sole proprietorship in Ohio?
No, a sole proprietorship has exactly one owner. Under ORC 1776.22(A), two or more people carrying on a business as co-owners for profit form a partnership, whether or not they intended to. Forming an LLC with a written operating agreement is the usual way to set ownership shares, duties, and what happens when someone leaves.
Can an Ohio sole proprietor elect S corporation tax treatment?
No, an S corporation election requires an eligible entity, and a sole proprietorship is not one. A sole proprietor who wants S corp treatment first forms an LLC or corporation, then files IRS Form 2553 within the deadline. Whether payroll and the added filings make the election worthwhile is a question for your accountant.
Does registering a trade name as an Ohio sole proprietor put my address on the public record?
Yes, the trade name application lists your name and business address, and Secretary of State filings are public. ORC 1329.01 requires both on the form. Sole proprietors who work from home often list the house. An LLC's public record instead shows the LLC's name and its statutory agent's address, which can be a service office.
Is bookkeeping harder for an Ohio LLC than for a sole proprietorship?
Only slightly for a single-member LLC, which reports income the same way a sole proprietor does by default. The added work is keeping a separate bank account and books in the LLC's name. A multi-member LLC is a partnership by default and files a separate federal partnership return each year, which usually means paying an accountant.
What happens to my sole proprietorship's contracts when I form an Ohio LLC?
They stay between you personally and the other party until both sides agree to move them. The new LLC is a different legal person, so leases, loans, and customer agreements signed as a sole proprietor do not transfer on their own. Ask each counterparty to assign or reissue important contracts in the LLC's name, and have an attorney review significant ones.
