Connecticut Seller’s Permit, Wholesale License & Reseller License

Residents of Connecticut have the highest per-capita income of any state in the entire U.S. They also enjoy a booming business sector, with a significant presence from the real estate, financial, insurance, and health industries. These facts surely go a long way toward explaining why this state continues to attract entrepreneurs from all over the country.

If you plan to launch a business in the Constitution State, you need to apply for certain kinds of permits and licenses. One of the most important of these is known in Connecticut as a sales and use tax permit, or resale number. If you plan to sell goods or services in this state, you probably need to get one of these permits.

This is a specialized type of business permit that is issued by every state that has a sales tax. It is known by a variety of different names around the U.S.—seller’s permit, resale license, wholesale license, sales tax permit, and reseller permit are just the more common names. Under any name, the purpose of this license is always the same: It gives businesses the right to charge sales tax on transactions.

Bewildered by all this? There’s no reason to be. FastFilings has made it easy to apply for your Connecticut seller’s permit. All you need to do is spend a few minutes filling out our handy online ordering form.

Do You Need a Seller’s Permit in Connecticut?

The answer is “yes” if any of the following conditions apply to your business operations in Connecticut:

You are engaged in the sale, lease, or rental of goods
You run a hotel, a motel, or a lodging house
You sell a taxable service

Incidentally, you need a separate reseller permit in Connecticut for every business location you operate. If you take over an existing business, you’ll have to obtain a new permit—you can’t use the one assigned to the old owner.

No matter what kind of business entity you operate—partnership, corporation, LLC, etc.—you need a wholesale license in Connecticut if you will be making sales in the state. Both wholesale and retail business are subject to this requirement.

There is no exception for low-volume businesses, but a “casual or isolated” sale made by an individual who is not ordinarily engaged in these transactions does not require a Connecticut seller’s permit.

What Is a Connecticut Seller’s Permit?

A Connecticut seller’s permit is the registration issued by the Connecticut Department of Revenue Services (DRS) that authorizes a business to collect state sales tax on taxable transactions and, when applicable, report use tax. You may also see it referred to as a reseller permit or sales tax permit, among other names, but all of these terms describe the same core registration required for tax compliance.

This permit connects your business to Connecticut’s sales and use tax system. It identifies your business for reporting purposes, establishes your filing obligations, and allows the state to track taxable activity tied to your sales, rentals, or services. Once issued, the Connecticut seller’s permit is tied to your specific business activities and locations, which is why changes such as opening a new location or purchasing an existing business can trigger additional registration steps.

For many businesses, the permit also plays a practical role beyond tax filings. Suppliers and wholesalers often ask for proof of registration during onboarding, sometimes referring to it informally as a wholesale license or a similar term. While labels vary, the underlying requirement remains the same—proper registration with DRS before engaging in taxable sales activity.

Seller’s Permit vs. Resale Certificate in Connecticut

A Connecticut seller’s permit is not the same thing as a resale certificate. They work together, but they have different purposes. As these terms are commonly confused, it’s worth taking the time to explain their individual functions.

A Connecticut seller’s permit is your registration to collect and remit tax on taxable sales.
A Connecticut resale certificate—officially called a Sales & Use Tax Resale Certificate—is a document used in a qualifying wholesale transaction so tax is not charged at the time of purchase because the items are being bought for resale. The certificate should be taken in good faith, meaning the facts should support that the purchase is truly for resale in the regular course of business.

Think of it this way: your Connecticut seller’s permit is about your authority to collect sales tax and your ongoing reporting responsibilities. A resale certificate in Connecticut is about a specific purchase where resale treatment applies.

A Connecticut resale certificate should be renewed at least every three years.

The state’s tax system separates the registration (your seller’s permit) from the resale certificate you provide to suppliers. If you sell both retail and wholesale, your setup and recordkeeping should reflect those separate roles.

How to Get a Connecticut Seller's Permit for Your Business

To obtain a seller’s permit, it’s always possible to register with the Connecticut Department of Revenue Services (DRS) through the state’s online system. This direct state filing option is available to any business that prefers to handle the process on its own.

Many businesses, however, choose a simpler route. FastFilings offers a streamlined online system that helps businesses prepare and submit their application for a wholesale license in Connecticut without dealing with the state portal on their own. The guided intake helps ensure key details—such as business structure, sales activity, and location information—are captured correctly, reducing delays caused by incomplete or inconsistent filings. It also enables busy managers and owners to save time on business filings and devote their energies to other tasks.

When Should I Get a Seller’s Permit in Connecticut?

You should apply for your Connecticut sales and use tax permit before you begin making taxable sales, taking payments, or issuing invoices for taxable transactions. Waiting until after you start selling can create headaches, such as uncollected tax, incorrect invoices, or a scramble to fix filings.

Common timing triggers include:

You’re about to launch an online store and will ship taxable goods to Connecticut buyers.
You’re signing your first wholesale supplier agreement and plan to buy inventory for resale.
You’re taking a booth at a craft fair, trade show, or seasonal event in Connecticut.
You’re adding a second location, warehouse, or storefront in Connecticut.
You’re expanding from services into taxable items or taxable service categories.

If your business sells through a marketplace, it’s still smart to confirm your registration obligations early. Marketplace rules can shift who collects tax on a given sale, but they do not eliminate your need to keep clean records or register when Connecticut rules require it.

How Long Is a Seller’s Permit Valid in Connecticut?

A Connecticut seller’s permit expires every two years, but is automatically renewed free of charge and mailed to your business provided that your account remains active and in good standing. In Connecticut guidance, the permit renewal is tied to ongoing compliance—filing required returns, keeping the account current, and maintaining accurate business information.

If your business stops operating, closes a location, or files a final return, you may need to close the account properly. If you later resume taxable sales, you may need a new reseller permit rather than relying on an old registration.

What Can I Do With a Seller’s Permit in Connecticut?

A Connecticut wholesale license/seller’s permit is mainly about tax collection authority and compliant reporting, but it also supports day-to-day operations in a few practical ways.

With a Connecticut seller’s permit, you can:

Collect Connecticut sales tax from customers on taxable retail transactions.
Remit sales and use tax to DRS through the assigned filing schedule.
Document resale transactions when you buy qualifying inventory for resale using a resale certificate (and maintain records that support those purchases).
Operate at temporary events (craft fairs, trade shows, pop-ups) with the correct tax registration in place.
Separate taxable and nontaxable sales more cleanly in your bookkeeping, which helps at filing time.
Support wholesale workflows when suppliers expect proof of your registration for trade accounts—it’s often described informally as a wholesale license in vendor onboarding language.
Reduce the risk of back-tax exposure by building correct tax collection into your checkout, invoicing, and POS systems from day one.

If your business buys goods from out of state for use in Connecticut and tax was not collected, use tax rules may apply.

Who Needs to Get a Connecticut Seller’s Permit?

Many businesses assume only retail stores need registration, but Connecticut’s rules reach far beyond traditional storefronts. If you engage in taxable sales activity connected to Connecticut, you should evaluate registration early.

You likely need a seller’s permit/reseller permit in Connecticut if you do any of the following:

Sell taxable goods at retail in Connecticut (in person or online).
Sell taxable services in Connecticut.
Rent or lease taxable items to Connecticut customers.
Operate lodging arrangements that fall under Connecticut’s taxable categories.
Sell at trade shows, fairs, craft events, markets, or pop-ups in Connecticut, even for a short run.
Run a contracting business that operates in Connecticut and is expected to hold the permit before providing services.
Maintain more than one Connecticut business location and need separate permits for each location.
Sell through a marketplace platform and still have a Connecticut registration requirement based on your business type.
Manufacture or wholesale goods and make sales in Connecticut that trigger registration.

Out-of-state businesses, including those that sell through online marketplaces, may be required to obtain a Connecticut wholesale license/seller’s permit once they exceed the state’s economic nexus threshold—generally more than 200 retail sales and $100,000 in gross receipts from Connecticut customers during the applicable 12-month measurement period, even if a marketplace facilitator collects and remits the tax.

Who Is Exempt From Needing a Seller’s Permit in Connecticut?

Not every transaction requires registration. Connecticut recognizes limited situations where a permit is not required.

Situations that may fall outside the permit requirement include:

Casual or isolated sales that are infrequent and nonrecurring, made by someone not operating a selling business.
Businesses with no taxable sales activity in Connecticut and no registration requirement under Connecticut rules.
Some out-of-state sellers who do not meet Connecticut’s remote seller thresholds and do not otherwise have a registration trigger.

Exemptions can be fact-specific. If a business crosses from occasional sales into ongoing selling activity, Connecticut may treat that shift as the point where registration is required. If you’re unsure, it’s safer to evaluate your specific sales model (online, event-based, wholesale, multi-location, marketplace) before assuming you’re exempt.

Even when a seller’s permit is not required, some businesses may still need to register to report and pay business use tax on taxable purchases where Connecticut tax was not collected.
