This business licensing guide covers what every entrepreneur and small business owner needs to know about forming a business, obtaining licenses, registering with state and county authorities, and maintaining compliance at the local level. Business license matters generate substantial search traffic because the requirements vary dramatically by state, county, and business type, and most new business owners only navigate the system once.
This business license guide explains how to form an LLC, when you need a DBA versus an LLC, how to file for a county business license, what permits apply to different business types, and where state law makes the process meaningfully different. Every state-specific business license guide linked from this page is written for the specific requirements, fees, forms, and county procedures that apply where the business operates.
What this business license guide covers
The business and licensing topic spans more ground than most new business owners realize. This business license guide and the supporting state guides cover six distinct areas of business formation and licensing practice, each with its own state-specific variations.
Business entity formation. Choosing the right entity structure (sole proprietorship, partnership, LLC, S-Corp, C-Corp) affects liability protection, taxation, and operational complexity. LLC formation is the most common choice for small businesses because it provides liability protection without corporate complexity. Each state has its own LLC formation rules, fees, and required filings. The choice between LLC and S-Corp tax treatment can produce significant tax savings for profitable businesses.
Federal tax identification. Most businesses need an Employer Identification Number (EIN) from the IRS. EINs are required for LLCs with multiple members, corporations, partnerships, businesses with employees, and businesses opening business bank accounts. Single-member LLCs can use the owner’s Social Security Number but most obtain an EIN anyway for banking purposes. EINs are free directly from the IRS.
State business registration. State business registration through the Secretary of State (or equivalent agency) is required for LLCs, corporations, and other registered entities. Sole proprietorships and general partnerships do not require state registration in most states. Registration creates the legal entity, provides public notice of the business existence, and establishes the registered agent for legal service.
County and city business licenses. Most businesses need at least one local business license. County business licenses (sometimes called business tax receipts, occupational licenses, or local business licenses) are obtained from the county tax collector or county business license office. Many counties also require a city business license if the business operates within incorporated city limits. Fees vary widely by jurisdiction and business type.
Industry-specific licenses and permits. Certain industries require specialized licenses beyond general business licenses. Regulated professions (medicine, law, real estate, accounting, cosmetology) require state professional licenses. Specific industries (alcohol, firearms, transportation, food service) require federal licenses. State sales tax permits are required for businesses selling taxable goods.
Sales tax and ongoing compliance. Businesses selling taxable goods or services must obtain state sales tax permits and file periodic sales tax returns. The frequency depends on sales volume (monthly, quarterly, or annually). Annual report filings, registered agent maintenance, and entity status renewals are ongoing compliance requirements for LLCs and corporations.
Universal business license guide: how business formation works regardless of state
Five core questions apply to business license matters regardless of which state controls. Each universal business license guide linked here addresses one of them in depth.
How to form an LLC in your state. LLC formation involves filing Articles of Organization with the state Secretary of State, paying the filing fee, designating a registered agent, and creating an Operating Agreement. After state formation, the LLC typically needs an EIN from the IRS, a business bank account, and applicable state and local business licenses. The business license guide on LLC formation walks through each step.
When you need a DBA versus LLC. A DBA (Doing Business As, also called fictitious name or assumed name) is simply a name under which a business operates that differs from its legal name. An LLC is a legal business entity providing liability protection. A sole proprietor or LLC can use a DBA. DBAs do not provide liability protection. Forming an LLC is appropriate when liability protection matters; a DBA alone is sufficient when only branding is the goal. The business license guide on DBA vs LLC covers the decision framework.
How to file a business license application. County and city business licenses require application to the local business license office. Required information includes the business legal name, location, type of business activity, ownership information, and fee payment. Some jurisdictions require zoning verification or other approvals before issuing the license. The business license guide on application covers the process by jurisdiction type.
Common business formation mistakes. New business owners form LLCs in Delaware or Nevada when their home state would be simpler and cheaper. They use their home address as the registered agent address and lose privacy. They miss the deadline for state initial reports. They forget to obtain required local business licenses after state formation. They commingle personal and business funds, undermining the liability protection the LLC was supposed to provide. The business license guide on common mistakes catalogs the costly errors.
When to hire a business formation service. DIY formation makes sense for simple single-member LLCs in your home state with straightforward business activities. Formation services make sense for first-time founders who want guided document preparation, multi-member LLCs requiring more complex operating agreements, businesses with specific tax election needs (S-Corp), or founders who do not want to navigate the state filing system themselves. The business license guide on formation services covers the decision framework.
Business license guide by state
State law controls business entity formation. Each state has its own filing fees, processing times, required documents, and ongoing compliance obligations. Delaware famously offers favorable corporate law that attracts large corporations but typically does not benefit small businesses. Nevada offers strong asset protection but adds complexity for out-of-state owners. Wyoming offers low fees and good privacy protections but limited business infrastructure. For most small businesses, the home state is the best formation state. Each state-specific business license guide is written for the specific procedures, fees, and timelines that apply.

What makes business licensing different across states
Beyond the universal business license guide content and state-specific procedures, certain state-level distinctions shape outcomes significantly.
State LLC filing fees. Filing fees vary from $40 (Kentucky) to $500 (Massachusetts). California charges an $800 annual minimum franchise tax in addition to formation fees, making it one of the most expensive states for LLC maintenance. Wyoming, Delaware, and New Mexico are among the lowest-cost states. The Small Business Administration business formation guide covers state-by-state considerations.
Annual report requirements. Most states require LLCs to file annual reports (or biennial reports in some states) confirming the entity remains in good standing. Filing fees range from $0 (no annual report required) to several hundred dollars. Failure to file annual reports can result in entity dissolution. Some states have particularly aggressive enforcement of annual report compliance.
Sales tax economic nexus. All states with sales taxes now require out-of-state sellers to collect and remit sales tax when sales into the state exceed economic nexus thresholds (typically $100,000 in annual sales or 200 separate transactions). The Streamlined Sales Tax Governing Board maintains nexus information by state. E-commerce businesses must monitor nexus across multiple states.
Professional licensing variations. Regulated professions have state-specific licensing requirements. A licensed cosmetologist in one state may need additional licensing to practice in another state. Real estate licensing reciprocity varies. Medical licensing is state-specific despite some federal reciprocity. The state professional licensing boards control these requirements. The Council of State Governments tracks professional licensing variations.
Business privilege and gross receipts taxes. Several states impose business privilege taxes (Alabama, Hawaii) or gross receipts taxes (Delaware, Nevada, Ohio, Texas, Washington) in addition to or instead of state corporate income tax. These taxes apply to revenue rather than profit, which affects business planning differently than income-based taxes. State-specific business license guides cover these tax implications.
Recommended business license guide resources
The right professional help depends on what you need to accomplish.
For LLC formation and document preparation, LegalZoom provides guided LLC formation in all 50 states with attorney consultation options. LawDepot offers DIY templates for operating agreements and business documents. Both services produce legally valid filings when used correctly. For most simple LLCs, these services save significant time compared to learning each state’s filing system from scratch. The LegalZoom review covers the formation service in detail.
For EIN application, apply directly through the IRS EIN application portal. The EIN is free and issued immediately when applying online. Avoid third-party services that charge fees for EIN application. The IRS prohibits these services from charging more than nominal fees, but many charge substantially more than nominal.
For business attorneys and ongoing legal needs, the American Bar Association legal help directory connects users with business attorneys through state bar referral services. Business attorneys handle complex formation situations, contracts, partnership disputes, and litigation. Initial consultations are often free. Specialized startup attorneys focus on technology businesses and venture-funded companies.
For federal business resources, the U.S. Small Business Administration provides free guidance, loan programs, and SBA-approved local resources. Small Business Development Centers (SBDCs) in every state offer free counseling to entrepreneurs. SCORE provides mentor matching with experienced business professionals. These federal and federally supported resources are underutilized by new business owners.
For trademark protection, the USPTO trademark portal handles federal trademark registration. State trademark registration through the Secretary of State provides state-level protection but limited compared to federal registration. Trademark protection requires more than business name registration; trademark and business name are separate legal concepts.
Frequently asked questions
The business license guide questions readers ask most often when starting any research come down to a handful of practical concerns. Each business license guide answer below covers the universal framework; specific procedures vary by state.
What is the difference between LLC and DBA?
An LLC (Limited Liability Company) is a legal business entity that provides personal liability protection for owners and is filed with the state’s Secretary of State. A DBA (Doing Business As, also called fictitious name or assumed name) is simply a name under which a business operates that differs from its legal name. A sole proprietor or LLC can use a DBA. DBAs do not provide liability protection. Forming an LLC is appropriate when liability protection matters; a DBA alone is sufficient when only branding is the goal.
How do I form an LLC?
The business license guide approach to LLC formation involves filing Articles of Organization with the state Secretary of State, paying the filing fee (ranges from $40 to $500 depending on state), designating a registered agent for service of process, and creating an Operating Agreement. After state formation, the LLC typically needs an Employer Identification Number from the IRS, a business bank account, and applicable state and local business licenses.
Do I need a business license to operate?
Most businesses need at least one business license, often more. The specific requirements depend on the business type, location, and structure. Common business license guide requirements include county or city business tax receipts (sometimes called business licenses), state professional licenses for regulated occupations, federal licenses for specific industries (alcohol, firearms, transportation), and sales tax permits for businesses selling taxable goods. The SBA business license guide covers federal license requirements.
What is a registered agent?
A registered agent is a person or business entity designated to receive legal documents (service of process) on behalf of an LLC or corporation. Every state requires LLCs and corporations to maintain a registered agent with a physical address in the state of formation. The agent can be the business owner, an attorney, or a commercial registered agent service. Commercial registered agent services typically cost $100-300 annually and provide privacy benefits compared to using the owner’s home address.
What is an EIN and how do I get one?
EIN stands for Employer Identification Number. It is a federal tax identification number issued by the IRS that identifies the business for tax purposes. EINs are required for LLCs with multiple members, corporations, partnerships, businesses with employees, and any business that wants to open a business bank account. Apply for an EIN free of charge directly through the IRS EIN application. Avoid third-party services that charge fees for EIN application.
Do single-member LLCs need an EIN?
Not always. The business license guide framework treats single-member LLCs as sole proprietorships by default and they can use the owner’s Social Security Number for tax purposes. However, an EIN is required if the LLC will have employees, if the owner wants to open a business bank account (most banks require EIN even for single-member LLCs), or if the LLC will be taxed as a corporation. Getting an EIN is free and simple even when not strictly required.
What is the difference between LLC and S-Corp?
An LLC is a legal business structure. An S-Corp (S Corporation) is a tax classification. An LLC can elect to be taxed as an S-Corp by filing Form 2553 with the IRS. The S-Corp tax election can reduce self-employment taxes for profitable businesses by paying the owner a reasonable salary (subject to payroll taxes) and treating remaining profits as distributions (not subject to self-employment tax). The S-Corp election is generally beneficial when net profit exceeds approximately $40,000-50,000.
How do I get a county business license?
County business licenses (sometimes called business tax receipts, occupational licenses, or local business licenses) are obtained from the county tax collector or county business license office in the county where the business operates. Application requires the business legal name, location, type of business activity, ownership information, and fee payment. Fees vary widely by county and business type. Many counties also require a city business license if the business operates within incorporated city limits.
What licenses do I need for a home-based business?
Home-based businesses typically need the same business licenses as other businesses: state business registration if forming an LLC or corporation, federal EIN if required, county or city business tax receipt, state sales tax permit if selling taxable goods, and any industry-specific licenses. Additionally, home-based businesses often need to verify compliance with local zoning regulations. Some residential zones restrict commercial activity. Homeowners associations may have additional restrictions.
How do I get a sales tax permit?
Apply through the state Department of Revenue (the agency name varies by state). Most states allow online application. Required information includes the business legal name, EIN or owner SSN, business location, anticipated sales volume, and types of products sold. Sales tax permits are typically free but require periodic sales tax filings (monthly, quarterly, or annually depending on sales volume). The Streamlined Sales Tax Governing Board maintains information on state sales tax procedures.
What is a fictitious business name?
A fictitious business name (also called DBA, doing business as, assumed name, or trade name depending on the state) is any name under which a business operates that differs from the business’s legal name. Filing a fictitious name registration is typically required at the county level. Filing puts the public on notice of who operates under the fictitious name. Fictitious name filings do not provide liability protection or trademark rights. Trademark protection requires separate federal trademark registration through the USPTO.
How long does business formation take?
The business license guide timeline varies significantly. State LLC formation processing times range from same-day (some states with expedited filing) to 4-6 weeks (states with standard processing during peak periods). Most states process formations within 1-2 weeks of receiving the filing. Federal EIN issuance is typically immediate when applying online. County business license issuance varies from same-day to 2-4 weeks. Plan formation timelines to account for the slowest step.
Related life event topics
Business and licensing matters frequently overlap with other county-level life events. The topics most commonly connected to this business license guide:
Tax and finance. Business taxation interacts with personal taxation through pass-through entity rules. Sales tax obligations, employment taxes, and business property taxes all connect to broader county tax matters. Business owners face tax complexity beyond personal tax filing.
Property and real estate. Business location decisions involve commercial real estate transactions, lease negotiations, and zoning compliance. Business property may have different tax treatment than residential property. Home-based businesses must comply with residential zoning.
Court records and legal. Business legal matters generate court records including contract disputes, partnership litigation, and intellectual property cases. Business owners may need to access court records for due diligence on potential partners, customers, or vendors.
Building and permits. Commercial construction, signage permits, occupancy permits, and zoning approvals are common business-related permit requirements. Restaurant and retail businesses face particularly complex permitting.
Estate and probate. Business succession planning is part of estate planning. Closely held business interests pass through probate or trust arrangements. Operating agreements should address what happens to ownership interests on death.
