Getting Registered: The First Step to Sales & Use Tax Compliance

What are sales and use tax registrations?

Sales and use tax registrations give a business the legal authority to collect and remit tax. Depending on the state, this registration may be called a sales tax permit, seller’s permit, or Certificate of Authority.

• Sales tax applies to taxable goods and services sold to customers.
• Use tax complements sales tax and is a self-assessed tax managed by the business itself. It applies when taxable items are used, stored, or consumed without sales tax being paid at the time of purchase. This frequently occurs in states where businesses manufacture or produce goods, as they must account for tax on raw materials or inventory diverted for internal use.

Without proper registration, a business cannot legally collect sales tax from customers or properly remit self-assessed use tax to the state. This gap in compliance—whether it's failing to register or registering too late—can result in penalties, audits, or liabilities that reach back several years.

Why Registration Matters

A business is legally required to register for sales tax once it has nexus in a state. Failure to register properly—or to maintain compliance after registration—can trigger fines, audits, or liability, and states enforce these rules rigorously. Requirements vary widely by state, and keeping up with account updates, license renewals, and changing rules can be challenging.

Compliance doesn’t end once a registration is obtained:

• States may impose ongoing requirements for licenses and account maintenance that differ significantly depending on your location and business type.
• Rules regarding sales channels, marketplace facilitation, and product classifications change frequently.

Given the complexity and the high stakes involved, businesses often seek professional guidance to ensure they remain compliant and avoid costly mistakes.

Types of Registration

If your business has a physical presence in a state—such as an office, employees, or inventory—you are generally required to register there. In contrast, businesses operating remotely may still have registration obligations in other states if they meet economic nexus thresholds based on sales revenue or transaction volume.  To read more about nexus, click the link here. In those cases, it is important to register appropriately, often under a “remote seller” designation when available.

Key considerations include:

• States with Home-Rule Jurisdictions: Certain states require additional attention due to local-level administration of sales tax. Businesses may be able to register once with the state for state-administered taxes, but additional registrations could be required for specific local jurisdictions that manage their own sales tax. Some jurisdictions may also require separate local business licenses, which are separate from sales tax registrations and should be reviewed independently.
• States with these types of complexities: Alaska (which has no statewide sales tax but local requirements), as well as Alabama, Arizona, and Louisiana.

Sales and use tax registration is rarely as simple as it first appears. Each state applies its own rules, thresholds, and administrative processes. As a result, determining where you are required to register—and which type of registration applies—often requires a detailed, multi-state analysis of your business activities.

As requirements vary widely by jurisdiction, many businesses rely on specialists to navigate these complexities and help ensure all obligations are properly addressed.

Tips for the Taxpayer

In recent years, states are becoming more insistent in the world of sales and use taxes with both regulation changes and enforcement. It is more important than ever for businesses to be aware of how sales tax affects them. Without an understanding of the varieties of sales and use tax, there is more potential for mistakes and audits. Businesses need to have policies and procedures in place that help them determine where, how much, and from whom to collect. Many companies may not have the knowledge, expertise, or time to build this foundation. An expert resource may be the best choice to help manage the world of sales and use tax and guarantee your business is tax compliant.
