How To Form An LLC In Ohio For A Skilled-Trades Business (2026)
Updated: August 2026 · Industry Advisors · Education, not legal or tax advice.
Ohio is one of the friendliest states in the country to form an LLC in — the filing fee is low, the annual maintenance is minimal, and the state does not require an annual report for standard LLCs. For skilled-trades founders (HVAC, electrical, plumbing, roofing, general contracting), the LLC is the easy part. The trade-specific licensure through the Ohio Construction Industry Licensing Board (OCILB) or municipal boards is where founders spend most of their setup time.
Step 1 · Ohio LLC Formation Basics
- Filing agency — Ohio Secretary of State, Business Services
- Form — Articles of Organization (Form 610)
- Filing fee — $99 est.
- Processing time — 3–7 business days online
- Statutory agent — Ohio resident or Ohio-registered entity
- Annual report — not required for standard Ohio LLCs
- State income tax — graduated 0–3.5% depending on income; Commercial Activity Tax applies over $150K gross receipts
Step 2 · The Skilled-Trades License Layer
Ohio splits construction licensing between state-level (OCILB) and municipal. General knowledge:
State-Level (OCILB) Trades
HVAC, electrical, plumbing, hydronics, and refrigeration are licensed at the state level. Requirements:
- 5 years of trade experience
- Pass the trade exam and business/law exam
- $25,000 minimum general liability insurance
- Fees: $25 exam + $175 initial license est., three-year renewal cycles
Municipal-License Trades
General contracting, roofing, remodeling, and specialty trades below the state threshold are licensed at the city or township level. Columbus, Cleveland, Cincinnati, Toledo, and Dayton each have their own boards, fee schedules, and insurance minimums. Rural townships often have none.
Step 3 · Workers' Comp — Ohio Is Unusual
Ohio is one of four monopolistic workers' comp states — coverage is purchased only from the Ohio Bureau of Workers' Compensation (BWC), not from private carriers. Every LLC with even one employee must register. Sole-owner LLCs may opt in but are not required. Premium rates are set annually by the BWC and vary by manual classification code; skilled-trades rates run $3–$9 per $100 of payroll est.
Step 4 · The Taxes Layer
- State income tax — graduated brackets, flowing through to member returns
- Commercial Activity Tax (CAT) — gross-receipts tax; kicks in above $150K annual gross receipts, current rate around 0.26% on receipts above the threshold. Confirm current threshold and rate before filing.
- Sales and Use Tax — register with Ohio Department of Taxation if you sell taxable materials or provide taxable installation services
- Municipal income tax — Ohio cities levy their own income tax; the LLC withholds and remits based on where work is performed (RITA and CCA are the two most common administrators)

LLC formation (required)
$99 est. — Ohio SoS Articles of Organization filing fee.
Statutory agent service (optional)
$100–$300/yr est. — Skip if you or a member is an Ohio resident with a physical address.
OCILB state trade license (HVAC, electrical, plumbing, hydronics, refrigeration)
$200–$400 est. initial license fee + exam. Requires 5-year experience documentation and $25K GL insurance minimum. Renews every 3 years.
Municipal license (GC, roofing, remodel)
$50–$500 est. per jurisdiction. Multiple cities = multiple licenses.
Workers' comp (Ohio BWC)
$3–$9 per $100 payroll est. plus $120 minimum administrative charge. A $60K payroll roughly runs $1,800–$5,400/yr in premium.
General liability insurance
$800–$2,500/yr est. for small trade contractors at $1M/$2M limits.
License bond (if required by jurisdiction)
$100–$400/yr est. premium on typical $10K–$25K bond values.
Typical first-year total for a small residential HVAC LLC: $3,500–$10,000 est.
Step 5 · Contracts And Consumer-Protection Rules
Ohio has a strong Consumer Sales Practices Act. Residential-improvement contracts over $25 must include specific disclosures, three-day right of rescission for door-to-door sales, and cannot include waivers of consumer rights. The Operating Agreement post covers the internal contracts; the customer-facing template needs Ohio-specific language.
Quick Check
Q1. A first-time HVAC contractor in Cleveland forms an LLC. Which two license layers apply?
Answer: OCILB state HVAC license + Cleveland municipal contractor registration.
Q2. A solo-owner Ohio roofing LLC hires one W-2 employee. Where does the workers' comp policy come from?
Answer: The Ohio Bureau of Workers' Compensation (BWC). Ohio is a monopolistic state — no private carrier is licensed to write the policy.
Q3. When does the Commercial Activity Tax start applying?
Answer: When annual Ohio gross receipts exceed $150,000. Confirm the current threshold at the Ohio Department of Taxation.
Where This Connects
The core LLC stack is the same as in every state: registered agent, EIN, Operating Agreement. Skilled-trades LLCs also layer in the OCILB license, workers' comp registration, and municipal permits — on the same calendar as the Q4 compliance close.
