Small Business Compliance Checklist (2026): Federal, State, and Local Requirements

# Small Business Compliance Checklist (2026): Federal, State, and Local Requirements

Running a business is hard enough without getting blindsided by a compliance deadline you didn't know existed. But that's exactly what happens to thousands of small business owners every year — a missed state filing, an overlooked tax deadline, a permit renewal that slipped through the cracks — and suddenly you're dealing with penalties, interest, or worse.

Here's the thing: compliance isn't complicated. It's just a lot of small requirements spread across federal, state, and local agencies, and none of them talk to each other. Nobody sends you a single master checklist. So you're piecing it together from IRS notices, state websites, and city clerk offices, hoping you don't miss something.

This guide is that master checklist. Every federal, state, and local compliance requirement your small business is likely to face in 2026, organized so you can actually manage it. Plus a downloadable annual compliance calendar that lays it out month by month.

Federal Compliance Requirements

Employer Identification Number (EIN)

If you haven't already, get your EIN. It's free, takes five minutes on the IRS website, and you need it for almost everything — opening a business bank account, filing taxes, hiring employees, applying for licenses.

What to know in 2026:

• Apply online at IRS.gov (available Monday-Friday, 7am-10pm ET)
• One EIN per responsible party per day
• International applicants must call or fax
• You need a new EIN if your business structure changes (sole prop → LLC, partnership → corporation)

Beneficial Ownership Information (BOI) Reporting

BOI reporting under the Corporate Transparency Act has been one of the most confusing new requirements for small businesses. The requirement is that most LLCs, corporations, and similar entities must report their beneficial owners to FinCEN.

2026 status:

• Companies formed before January 1, 2024 had an original deadline of January 1, 2025
• Multiple deadline extensions and legal challenges have created confusion
• Check FinCEN.gov for the current enforcement status — this has been a moving target
• When active, filing is free through FinCEN's online portal

Who's exempt: Companies with 20+ full-time employees AND $5M+ in gross receipts AND a physical US office. Also: banks, credit unions, insurance companies, public companies, and certain other regulated entities.

For the full breakdown, read our BOI reporting guide.

ACA (Affordable Care Act) Requirements

If you have 50+ full-time equivalent employees, you're an Applicable Large Employer (ALE) and must:

• [ ] Offer minimum essential health coverage to full-time employees
• [ ] File Form 1095-C to each employee by March 3
• [ ] File Form 1094-C with the IRS by February 28 (paper) or March 31 (electronic)

Penalty for non-compliance: $2,900 per full-time employee (2026, adjusted annually) if you fail to offer coverage and at least one employee gets a marketplace subsidy.

Under 50 employees? No ACA employer mandate, but you can still offer coverage through SHOP or private plans. There may be small business health care tax credits available.

OSHA (Occupational Safety & Health)

If you have employees, OSHA applies to you. Key requirements:

• [ ] Maintain a safe workplace (general duty clause)
• [ ] Post OSHA "Job Safety and Health" poster in the workplace
• [ ] OSHA Form 300 Log — Record all workplace injuries/illnesses (if 10+ employees)
• [ ] OSHA 300A Summary — Post in workplace February 1 through April 30
• [ ] Electronic reporting — If 250+ employees, or 20-249 employees in certain industries, submit injury data electronically by March 2

Exemption: Businesses with 10 or fewer employees are exempt from routine OSHA recordkeeping (but not from safety requirements).

ADA (Americans with Disabilities Act)

If you have 15+ employees, Title I of the ADA requires you to:

• [ ] Provide reasonable accommodations for qualified employees with disabilities
• [ ] Not discriminate in hiring, firing, pay, promotion, or other employment practices
• [ ] Keep medical information confidential and in separate files

Title III (Public Accommodations) applies to all businesses open to the public regardless of size — your physical space and website must be accessible.

Other Federal Requirements

• [ ] FLSA (Fair Labor Standards Act) — Minimum wage ($7.25 federal, but check your state), overtime rules, child labor laws, recordkeeping
• [ ] FMLA — If 50+ employees, provide up to 12 weeks unpaid leave for qualifying reasons
• [ ] EEOC reporting — If 100+ employees (or 50+ federal contractors), file EEO-1 report annually
• [ ] I-9 verification — For every employee hired, verify identity and work authorization within 3 business days

State Compliance Requirements

State requirements vary enormously. Here are the categories you need to address in every state where you operate.

Annual Reports / Statements of Information

Most states require businesses to file an annual or biennial report to maintain good standing. Miss it, and your entity can be administratively dissolved.

Key facts:

• Filing frequency varies: annual (most states), biennial (some), or none (a few)
• Costs range from $0 (no filing required) to $800+ (California's franchise tax minimum)
• Deadlines vary: anniversary of formation, calendar year, or fiscal year
• Most states allow online filing through the Secretary of State website

For the full state-by-state breakdown of deadlines and costs, see our annual business filing requirements guide.

State Tax Filings

• [ ] State income tax — If your state has one (most do; exceptions: TX, FL, WY, NV, SD, WA, AK, TN, NH)
• [ ] Franchise tax — Some states charge this regardless of income (Delaware, Texas, California, others)
• [ ] Sales tax — If you sell taxable goods or services, register, collect, and remit
• [ ] Use tax — On purchases where sales tax wasn't collected
• [ ] State estimated taxes — Quarterly, same schedule as federal in most states

Workers' Compensation Insurance

Nearly every state requires workers' comp for businesses with employees. There is no federal workers' comp requirement (except for federal employees and certain industries).

• [ ] Obtain workers' comp coverage before your first employee starts
• [ ] Rates based on industry classification codes and payroll
• [ ] Texas and South Dakota are the only states where it's truly optional for private employers
• [ ] Even in optional states, going without exposes you to significant lawsuit risk

State Unemployment Insurance (SUI)

If you have employees, you must:

• [ ] Register with your state's workforce/unemployment agency
• [ ] Pay state unemployment taxes (rates vary by state and your claims history)
• [ ] File quarterly wage reports
• [ ] Respond to unemployment claims promptly (affects your rate)

State-Specific Employment Laws

Beyond federal minimums, many states add:

• [ ] Higher minimum wage — Check your state (many are $12-16+/hr in 2026)
• [ ] Paid sick leave — Required in 15+ states and growing
• [ ] Paid family leave — CA, NY, NJ, WA, MA, CT, CO, OR, and others
• [ ] Pay transparency — CO, CA, NY, WA, and others require salary ranges in job postings
• [ ] Ban the box — Many states restrict asking about criminal history on applications
• [ ] Non-compete restrictions — CA bans them entirely; many states are restricting them

Local Compliance Requirements

Local requirements are the ones most businesses miss because they're the hardest to find. Check with your city, county, and any special districts.

Business License / Business Tax Certificate

• [ ] Almost every city and county requires a general business license
• [ ] Costs: typically $50-500/year, sometimes based on gross receipts
• [ ] Renewal: usually annual
• [ ] Home-based businesses need these too — many owners don't realize this

For state-by-state details, check our business license requirements guide.

Zoning and Land Use

• [ ] Verify your business location is zoned for your use (commercial, retail, industrial, home occupation)
• [ ] Home-based businesses may need a Home Occupation Permit
• [ ] Signage permits if you're putting up exterior signs
• [ ] Special use permits for certain business types (auto repair, daycare, food service)

Health and Safety Permits

If you deal with food, health, or public safety:

• [ ] Food service permit — restaurants, food trucks, catering, food manufacturers
• [ ] Health department inspection — annual for food businesses
• [ ] Fire department permit — occupancy limits, fire safety systems, hazardous materials
• [ ] Building permits — for any construction or significant renovation
• [ ] Alarm permits — some cities require registration of security alarms

Professional and Industry Licenses

Beyond the general business license, many professions require specific licensing:

• [ ] Contractors (general and specialty)
• [ ] Real estate agents and brokers
• [ ] Cosmetologists and barbers
• [ ] Electricians and plumbers
• [ ] Insurance agents
• [ ] Architects and engineers
• [ ] Healthcare professionals
• [ ] Accountants / CPAs

• Bank Secrecy Act / AML compliance
• PCI DSS compliance (credit card processing)

• Cookie consent (especially if EU customers — GDPR)
• Product safety / CPSC compliance
• Shipping regulations (hazardous materials, alcohol, restricted items)

What Happens When You Miss a Deadline

Let's be real about the consequences:

Federal Penalties

State Penalties

Local Penalties

The point isn't to scare you. It's that most of these penalties are completely avoidable with a calendar and a checklist.

Building Your Compliance System

Here's how to stay on top of everything without losing your mind:

1. Create Your Compliance Calendar

Download our Annual Compliance Calendar and customize it for your business. Add your specific state deadlines, local renewal dates, and industry-specific requirements.

2. Set Reminders 30 Days Early

For every compliance deadline, set two reminders:

• 30 days before: start preparing the filing or renewal
• 7 days before: submit if you haven't already

3. Automate What You Can

• Payroll service handles 941s, W-2s, unemployment filings, and payroll tax deposits
• Accounting software tracks estimated tax dates and amounts
• Registered agent handles annual report reminders (and often files for you)
• Sales tax automation (Avalara, TaxJar) handles collection and filing across states

4. Work With Professionals

You don't have to do all of this yourself:

• CPA/tax preparer — tax filings, estimated payments, payroll
• Business attorney — entity maintenance, contracts, employment law
• Registered agent — annual reports, good standing
• Insurance agent — workers' comp, liability, annual reviews
• HR platform — employment law compliance, handbook, onboarding

5. Keep a Compliance Folder

Physical or digital — one place where you store:

• All filed returns and confirmations
• Business license and permit copies
• Insurance certificates
• Employee records (I-9s, W-4s)
• Professional license renewals
• Annual report confirmations

The Bottom Line

Compliance is a cost of doing business, but it doesn't have to be a burden. The businesses that get in trouble aren't the ones with complicated compliance requirements — they're the ones who didn't know the requirements existed until a penalty notice showed up.

Set up your calendar. Automate what you can. Work with professionals for the complex stuff. And check in quarterly to make sure nothing fell through the cracks.

You started a business to build something — not to worry about filing deadlines. A good system lets you get back to the building.
