State and Local Tax Basics for Small Businesses

State and local tax obligations vary by location, entity, activity, and business footprint. Learn what to check and where to verify current requirements.

Last updated: October 9, 2026

Direct answer

A U.S. business may need to consider state income, franchise or excise taxes, sales and use tax, local licenses, gross receipts taxes, and payroll obligations. Which ones apply depends on the business structure, location, employees, products or services, and where it has tax nexus. Use this as a checklist, then verify each requirement with the relevant state and local agencies.

The part people miss

Federal filing requirements are only one part of a business’s compliance checklist. State and local rules can differ across borders and can change when a business hires, sells into another state, or adds a location.

Why it varies

States, counties, and cities create their own tax and licensing rules. A general article can help identify questions, but cannot determine whether a specific business has nexus, sells taxable goods or services, or meets local licensing requirements.

The taxes to look for

  1. 1

    Check state income, franchise, or excise taxes

    Some states tax pass-through business income at the owner level; others may impose franchise, privilege, or excise taxes on certain entities or activities. Rules depend on state, entity classification, and business facts. Do not assume that a federal tax classification answers every state question.

  2. 2

    Review sales and use tax nexus

    States define which goods and services are taxable and when a seller must register, collect, and remit. Physical presence, employee or inventory locations, and economic thresholds may matter. Check the destination state’s current rules before collecting or remitting tax.

  3. 3

    Look for city and county licenses or permits

    Some local governments require a general business license; others rely on activity-specific permits, zoning, or professional licensing. Requirements and fees vary by address and business activity, so confirm with the relevant city or county office.

  4. 4

    Ask whether a local gross-receipts or business tax applies

    Some jurisdictions impose taxes or fees based on gross receipts or business activity rather than net profit. Thresholds, exemptions, apportionment, and filing schedules vary. Verify the local rule before estimating a liability.

  5. 5

    Check employer and payroll obligations

    If you have employees, state and sometimes local withholding, unemployment insurance, workers’ compensation, and registration rules may apply. Check the state labor and revenue agencies and the rules for each work location.

  6. 6

    Keep a location-by-location compliance record

    Record where employees work, where inventory is stored, where services are performed, and where customers are located. Revisit registrations and filing dates when the footprint changes; ask a tax professional about multi-state nexus.

Useful resources

  • Your state revenue department

    The official source for rates, registration, and filing dates where you operate.

  • Your city business license office

    Local licenses and permits, often missed, often cheap, often dated.

Key takeaways

  • State and local obligations vary by location, entity, activity, and business footprint.
  • Check income, franchise or excise taxes, sales/use tax, licenses, gross receipts, and payroll obligations where relevant.
  • Nexus and taxability rules can apply across state lines; thresholds and exemptions vary.
  • Local licenses are not universal; ask the city or county that governs each work location.
  • Use current government guidance or a qualified professional to confirm a specific obligation.

Frequently asked questions

Does every small business owe state income tax?

No single rule applies to every business. State income-tax treatment depends on the state, federal and state entity classification, owner residence, business activity, and nexus. Some jurisdictions have other entity or activity taxes instead.

When must a business register for sales tax?

It depends on whether the business sells taxable items or services and has physical or economic nexus under the relevant state’s current law. Check registration thresholds and rules before collecting tax; do not assume every seller must register before a first sale.

Do all cities require a general business license?

No. Licensing, zoning, and permit requirements vary by city, county, profession, and business activity. Check the government offices for every location where you operate.

What is a local gross-receipts tax?

Some jurisdictions impose a tax or fee measured by receipts or business activity rather than net profit. The base, thresholds, exemptions, and filing rules are local and should be verified with the jurisdiction.

Where can I find the official state or local rules?

Start with the relevant state revenue or tax agency and the city or county business-licensing office. For multi-state sales or employees, consult the applicable agencies or a qualified tax professional.
