How to Register a Business for State Tax Accounts in the U.S.

Registering a business for state tax accounts is a critical compliance step after entity formation. State tax registration ensures that a business can legally collect, report, and remit applicable taxes based on its operational footprint. Failure to register properly may result in penalties, interest, and enforcement actions by state tax authorities.

This guide outlines the technical process of state tax registration, required accounts, and compliance considerations for businesses operating across U.S. states.

What Is State Tax Registration?

State tax registration is the process of enrolling a business with a state’s revenue or taxation department to obtain authorization to report and pay applicable state-level taxes. The specific tax accounts required depend on the business’s activities, structure, and nexus within the state.

Registration typically occurs after entity formation and before commencing taxable activities.

When Is State Tax Registration Required?

A business must register for state tax accounts when it establishes tax nexus, which may occur through:

  • Physical presence (office, warehouse, employees)
  • Economic nexus (sales thresholds exceeded)
  • Remote sales or digital services
  • Hiring in-state employees
  • Owning or leasing property
  • Providing taxable goods or services within the state

Each state defines nexus independently, and thresholds vary by tax type.

Common State Tax Accounts Businesses Must Register For

1. Sales and Use Tax Account

Required for businesses selling taxable goods or services. Registration allows the business to collect sales tax and remit it to the state.

Applies to:

  • Retailers
  • E-commerce businesses
  • Service providers in taxable states

2. Employer Withholding Tax Account

Mandatory for businesses with employees in the state. This account is used to withhold and remit state income tax from employee wages.

Applies to:

  • Corporations
  • LLCs with employees
  • Partnerships with payroll obligations

3. State Unemployment Insurance (SUI)

Required for employers to fund state unemployment benefits. Registration is typically handled through the state labour or workforce agency.

4. Franchise or Privilege Tax Accounts

Some states impose an annual franchise or privilege tax for the right to do business in the state, regardless of profitability.

Common states include:

  • California
  • Texas
  • Delaware
  • New York

5. Industry-Specific Tax Accounts

Certain industries require additional registrations, such as:

  • Excise taxes
  • Alcohol and tobacco taxes
  • Fuel taxes
  • Gross receipts taxes

Step-by-Step Process to Register for State Tax Accounts

Step 1: Confirm Business Formation

Ensure the entity is legally formed with the Secretary of State and that Articles of Incorporation or Organization have been approved.

Step 2: Obtain an EIN

An Employer Identification Number (EIN) issued by the IRS is required for most state tax registrations.

Step 3: Identify Required Tax Accounts

Determine which tax accounts apply based on:

  • Business activities
  • State nexus rules
  • Employment status
  • Revenue thresholds

Step 4: Register with the State Revenue Agency

Most states offer online registration portals. Required information typically includes:

  • Legal business name
  • EIN
  • Business address
  • Entity type
  • Ownership details
  • Start date of taxable activity

Step 5: Register with State Labor Agencies (If Applicable)

Employers must separately register for unemployment insurance and workforce taxes.

Step 6: Maintain Ongoing Compliance

Once registered, businesses must:

  • File periodic tax returns
  • Remit taxes by statutory deadlines
  • Update account information as changes occur
  • Close accounts properly if operations cease

Multi-State Businesses and Expanded Compliance

Businesses expanding into new states must register for tax accounts before commencing operations in each jurisdiction. Multi-state compliance often involves:

  • Tracking economic nexus thresholds
  • Managing multiple filing calendars
  • Reconciling sales and payroll across states

Professional oversight is recommended to avoid compliance gaps.

Common Registration Errors to Avoid

  • Registering late after taxable activity begins
  • Registering for unnecessary tax accounts
  • Failing to close inactive accounts
  • Misclassifying taxable services
  • Overlooking local or municipal tax obligations
