Seller’s Permit vs. Business License: What’s the Difference?
Many new entrepreneurs confuse these two documents.- Business License: Issued by your city or county, giving you the legal right to operate a business in that jurisdiction.
- Seller’s Permit: Issued by the state (Department of Revenue) specifically to allow you to collect sales tax from customers and report it to the government. You often need both to be fully legal.

When Do You Need A Seller’s Permit?
You generally need to register for sales tax in a state when your business has a registration obligation there. That obligation may arise from physical nexus, economic nexus, or other state-specific rules.Physical Nexus
Physical nexus occurs when a business maintains a presence in a state. Examples may include:- An office, store, or warehouse.
- Employees or other business personnel working in the state.
- Inventory stored in the state, including inventory held by a third-party fulfillment provider.
- Other activities that create a tax obligation under state law.
Economic Nexus
Economic nexuslets states require certain remote sellers to collect sales tax based on their sales activity, even without a physical presence.States set their own thresholds and measurement rules. Some focus on sales revenue, while others apply additional criteria. Many states have eliminated transaction-count thresholds, but businesses should not assume that every state follows the same rule.An online retailer based in one state sells products to customers across several states. If sales into another state exceed that state’s applicable economic nexus threshold, the retailer may need to register, collect tax on taxable sales, and file returns.Review each state’s current remote-seller guidance before deciding whether registration is required.Do Marketplace Sales Create a Registration Requirement?
Selling through Amazon, Walmart Marketplace, or another marketplace does not automatically eliminate a seller’s registration obligations.Marketplace facilitatorsoften collect and remit sales tax on transactions covered by applicable marketplace laws. However, sellers may still have separate obligations for sales on their own website, physical presence, inventory, or other activities.Marketplace sales may also count toward an economic nexus threshold, depending on state rules and how the state treats those transactions.For example, a retailer might sell through a marketplace that collects tax on its behalf while also selling through its own Shopify store. The retailer must assess its registration and collection obligations based on the applicable state rules and its combined business activities.How to get a Seller’s Permit?
Getting a seller’s permit is simple, but the process may vary by state. The cost of a seller’s permit also varies. Most states don’t charge any fees for the license. Still, some states require a registration fee, security deposit, and renewal charges.
You can find the seller’s permit application on each state’s Department of Revenue website. For instance, the applications in Florida and California are available on the respective states’ websites.
Economic Nexus Update
In the past, many states required a permit if you had 200 transactions OR $100,000 in sales. Note: Many states (including Illinois, South Dakota, Utah, and Wyoming) have recently removed the “200 transaction” threshold. Now, you typically only need a permit if your sales exceed $100,000 in that state, though you should check specific state rules as they evolve.Special Note for E-commerce Sellers
Even if you sell exclusively on marketplaces that collect tax for you (Marketplace Facilitators), most states still require you to register for a seller’s permit in your home state or states where you have physical inventory.Documents Needed to Apply
The following documents are usually required for sales tax permit registration. However, depending on your business entity and the nature of your business, the requirements may vary.
- Business name and address
- Social Security Number (SSN) or Employer Identification Number (EIN)
- Projected monthly sales
- Description of goods sold
- Bank Account Information: While some states request this to verify your identity or set up automated tax payments (EFT), it is not a universal requirement for the permit itself.
Steps on How to Get a Seller’s Permit
- Firstly, identify where you have nexus. This includes your home state and any state where you have employees, inventory (like an FBA warehouse), or high sales volume.
- Next, visit the State’s Department of Revenue Website and look for “Business Registration.”
- Subsequently, complete the application by providing your business details.

How Much Does A Seller’s Permit Cost?

Some states issue permits without an application fee, while others charge registration fees or require a security deposit.The total cost may also include separate business license fees, local registrations, renewal charges, or other requirements.For example, a business may pay a state registration fee and still need a separate local business license. These are separate expenses and should not be treated as a single universal seller’s permit fee.Before applying, confirm:- The initial registration fee.
- Any refundable or required security deposit.
- Renewal fees and deadlines.
- Separate local licensing charges.
- Whether fees differ for in-state and remote sellers.
How Long Does It Take To Get a Seller’s Permit?
Processing times depend on the state, how you apply, and whether the tax agency needs more information.Some online applications provide registration details quickly. Others require manual review or supporting documents. A physical permit or certificate may arrive later than the online confirmation.Check the state’s estimated processing time and monitor your application for requests or notices. Do not rely on a single nationwide processing estimate.If you have a registration deadline, apply early enough to address potential delays.Renewal of Seller’s Permit
Renewal requirements depend on the state and registration type.Some states issue permits that remain active until the business closes or the state cancels the account. Others require periodic renewal, updated business information, or additional fees.For each state where you register, record:- The permit’s expiration date, if applicable.
- Renewal deadlines and fees.
- Required business information updates.
- Filing and payment obligations.
- Procedures for closing or canceling the account.
Common Mistakes to Avoid
- Registering in the wrong states: Registering everywhere is not a substitute for determining where your business has a legal obligation. Review physical nexus, economic nexus, and state-specific requirements before applying.
- Assuming marketplace collection covers every sale: Marketplace facilitators may collect tax on covered transactions, but direct sales and other business activities can create separate obligations. Review each state’s rules.
- Using the wrong business information: Ensure that your legal business name, tax identification number, and entity details match your official records.
- Forgetting filing obligations: Registration can create ongoing reporting duties. Track return deadlines and file required returns, including zero returns when required by the state.
- Treating seller’s permit as a resale certificate: A seller’s permit authorizes you to collect sales tax when required. A resale certificate documents an eligible tax-exempt purchase for resale. Do not use the terms interchangeably.
