In the United States, licensing requirements can come from federal, state, county, or city authorities. The requirements depend heavily on the business activity, location, industry, and applicable regulations. The SBA notes that state, county, and city requirements can differ significantly.

A business may need several different approvals rather than one universal business license.

Why Business Licensing Matters

Licensing and permit requirements can affect whether and how a company is allowed to operate.

Businesses may need to review:

• General business registrations

• Professional licenses

• Industry-specific licenses

• Local business licenses

• Building permits

• Zoning approvals

• Health and safety permits

• Environmental permits

• Sales-tax registrations

• Federal licenses

• State registrations

• County or city permits

• Renewal requirements

The SBA recommends determining the business location and structure first because those factors help determine applicable registration, tax, licensing, and permitting obligations.

Federal, State, and Local Requirements

Licensing requirements can exist at multiple government levels.

Federal Requirements

Certain regulated activities may require federal licenses or permits.

Examples can include businesses involved in:

• Agriculture

• Alcoholic beverages

• Broadcasting

• Commercial aviation

• Transportation activities

• Nuclear materials

• Certain regulated products

• Other federally regulated activities

The relevant federal agency depends on the business activity.

State Requirements

States commonly regulate a broader range of business activities.

Depending on the state and industry, requirements may involve:

• Professional licensing

• Sales-tax registration

• Contractor licensing

• Health-related licensing

• Occupational licensing

• Industry-specific permits

• State business registration

• Employment-related registrations

The exact requirements vary by state.

County and City Requirements

Local governments can impose additional requirements.

These may include:

• Local business licenses

• Zoning approvals

• Building permits

• Health permits

• Fire-safety approvals

• Sign permits

• Occupancy approvals

• Local tax registrations

• Industry-specific permits

The SBA specifically notes that local governments determine many county- and city-level licensing and permitting requirements.

Business Structure and Registration

Business structure can affect registration and compliance obligations.

Common structures include:

• Sole proprietorships

• Partnerships

• Limited liability companies

• Corporations

• Nonprofit organizations

An LLC or corporation may need to register with a state and may also need registration in other states where it conducts sufficient business activity.

Businesses expanding across state lines may also need foreign qualification in additional states.

Licenses vs. Permits

The terms are sometimes used interchangeably, but they can serve different purposes.

A license generally authorizes a person or business to conduct a regulated activity.

A permit commonly authorizes a specific activity, location, construction project, operation, or condition.

Examples may include:

The exact terminology and requirements vary by jurisdiction.

Industry-Specific Licensing

Some industries face more extensive regulatory requirements.

Examples can include:

• Construction

• Restaurants

• Healthcare

• Transportation

• Financial activities

• Childcare

• Alcohol-related businesses

• Agriculture

• Environmental operations

• Professional practices

• Certain retail activities

The SBA identifies construction, restaurants, plumbing, retail, auctions, farming, dry cleaning, and vending among activities that may be regulated at state or local levels.

Zoning and Location Requirements

Business licensing is closely connected to location.

Before operating from a physical property, businesses may need to determine whether the intended activity is permitted under local zoning rules.

Potential considerations include:

• Commercial versus residential zoning

• Permitted business activities

• Parking requirements

• Signage

• Building occupancy

• Home-based business restrictions

• Environmental restrictions

• Special-use approvals

The SBA notes that zoning requirements can restrict or prohibit certain business activities in particular locations.

Professional and Occupational Licensing

Certain occupations require individual professional credentials in addition to business-level registrations.

Examples can include:

• Healthcare professionals

• Attorneys

• Accountants

• Contractors

• Engineers

• Electricians

• Plumbers

• Real-estate professionals

• Cosmetology professionals

The business should determine whether licensing applies to the company, individual workers, or both.

Renewals and Ongoing Compliance

Obtaining a license is usually not the end of the compliance process.

Some licenses and permits expire periodically and require renewal. The SBA recommends tracking renewal dates because requirements and schedules vary.

An ongoing compliance system can track:

• License name

• Issuing authority

• License number

• Issue date

• Expiration date

• Renewal deadline

• Responsible employee

• Required documentation

• Renewal status

• Related inspections

• Associated permits

Businesses can use a centralized compliance calendar to reduce the risk of missing renewal deadlines.

Business Expansion and Multi-State Compliance

Expanding into another state can create additional registration and licensing obligations.

A company may need to review:

• Foreign qualification

• State business registration

• State tax obligations

• Local business licenses

• Professional licensing

• Sales-tax requirements

• Zoning

• Industry-specific permits

• Local reporting requirements

The SBA explains that businesses expanding into new states may need foreign qualification and may also face additional taxes and annual reporting requirements.

Business Compliance Records

Companies should maintain organized records of licenses and permits.

A compliance file may contain:

• Applications

• Approval letters

• License certificates

• Permit documents

• Renewal confirmations

• Inspection reports

• Correspondence with regulators

• Fee records

• Supporting documents

• Internal compliance reviews

Digital records should be backed up and access should be restricted appropriately.

Common Licensing Mistakes

Businesses can encounter problems when they:

• Assume one license covers every activity

• Ignore county or city requirements

• Operate from a location without checking zoning

• Miss renewal deadlines

• Fail to update business information

• Expand into another state without reviewing requirements

• Confuse professional and business licensing

• Fail to maintain supporting records

• Rely on outdated regulatory information

• Assume requirements are identical across states

Requirements should be confirmed with the relevant government authority rather than inferred from another business or jurisdiction.

Practical Licensing Workflow

A structured process can help businesses organize licensing requirements:

Identify Activity → Confirm Location → Check Federal Rules → Check State Rules → Check Local Rules → Apply → Track Approval → Renew → Review Changes

The process should be revisited when the business:

• Changes location

• Adds a new product or activity

• Expands into another state

• Changes ownership

• Changes its legal structure

• Renovates a facility

• Adds regulated personnel

• Changes operating hours or facility use

Recent Developments

Current SBA guidance continues to emphasize that business licensing and permitting requirements depend on business activities and location. The SBA's licensing guidance was updated in March 2026 and continues to direct businesses toward federal agencies, state authorities, and local governments for applicable requirements.

Businesses also need to consider ongoing compliance rather than treating licensing as a one-time startup task. The SBA identifies annual or biennial reports, tax registrations, license renewals, and other continuing obligations that may apply depending on the business structure and jurisdiction.

Frequently Asked Questions

What is a business license?

A business license is an authorization or registration that may be required by a government authority for a business to conduct particular activities in a specific jurisdiction.

Does every business need a business license?

Not necessarily. Requirements depend on the business activity, location, industry, structure, and applicable federal, state, and local rules.

Do businesses need licenses from both state and local governments?

Some businesses do. State, county, and city requirements can overlap depending on the activity and location.

Do business licenses expire?

Some licenses and permits have renewal periods, while others may have different validity requirements. Businesses should confirm expiration and renewal rules with the issuing authority.

What happens when a business expands to another state?

The business may need additional registration, foreign qualification, licenses, permits, tax registrations, or local approvals depending on its activities and presence in the new state.

Conclusion

Business licensing involves more than obtaining a single document. Companies may need to coordinate federal, state, county, and city requirements, along with zoning, professional credentials, tax registrations, permits, renewals, and ongoing compliance records.

Because requirements depend heavily on the business activity and location, companies should verify requirements with the appropriate government authorities before beginning operations or expanding.

Maintaining an organized licensing calendar and keeping current copies of permits, approvals, and related records can also support ongoing compliance.
