Connecticut Sales Tax Guide for New Businesses

Connecticut sales tax can feel simple at first glance, but once a business begins selling taxable goods or services, the compliance details matter. Registering correctly, charging the right rate, collecting exemption certificates, and filing on time are all part of staying in good standing with the Connecticut Department of Revenue Services (DRS).

For founders launching a company in Connecticut, sales tax is not just an accounting issue. It affects pricing, checkout settings, bookkeeping workflows, inventory records, and the timing of your tax filings. If your business is structured as an LLC, corporation, or another entity, the responsibility to collect and remit tax still falls on the business once taxable sales begin.

This guide walks through the basics of Connecticut sales tax for new businesses, including what is taxable, who must register, how permits work, common exemptions, and practical compliance steps.

What Connecticut Sales Tax Covers

Connecticut imposes sales and use tax on the retail sale, lease, or rental of most tangible personal property and on many taxable services. The general state rate is 6.35%, and Connecticut does not add separate local sales taxes.

In practical terms, that means a business may need to charge Connecticut sales tax on:

• Physical products sold at retail
• Many digital goods and software transactions
• Certain taxable services listed under Connecticut law
• Rentals and leases of taxable property

Some categories have special rates or special treatment, so the taxability of a specific item should always be checked before it is added to your product catalog or service menu.

Who Needs to Register

A business generally needs a Connecticut Sales and Use Tax Permit if it intends to do any of the following in the state:

• Sell or lease goods
• Sell taxable services
• Operate a hotel, motel, lodging house, or bed and breakfast
• Sell at a one-day event such as a flea market, craft show, trade show, antique show, or fair

The permit requirement applies broadly to business entities, including individuals, partnerships, corporations, and LLCs. If you are making taxable sales in Connecticut, you should not wait until tax season to register.

The DRS also requires a separate permit for each business location when applicable. If you buy an existing business, you generally need your own permit rather than relying on the previous owner's registration.

How to Register for a Connecticut Sales Tax Permit

Registering for sales tax in Connecticut is typically done through the state's online business registration system, myconneCT.

A typical registration process includes:

1. Gather your business information.
2. Complete the business registration application.
3. Submit the request for a Connecticut Sales and Use Tax Permit.
4. Pay the required registration fee.
5. Display the permit where customers can see it if required.

Businesses should keep the permit accessible in their records as well. If you operate multiple locations, verify whether each location requires its own registration.

If you are forming a new company, it is usually better to handle formation, registration, and tax setup in a deliberate order rather than treating them as separate afterthoughts. A clean launch makes bookkeeping and compliance much easier later.

What Is Taxable in Connecticut

Connecticut taxes a broad range of goods and certain services, but not everything is taxable. The key is to identify whether your product or service falls inside a taxable category before you begin collecting tax.

Common taxable categories include:

• Retail sales of tangible personal property
• Some digital goods and electronically delivered software
• Certain repair, maintenance, and professional support services
• Lodging and similar occupancy-related charges

That said, many businesses also sell exempt items or make exempt sales. Exemption rules are one of the most important parts of Connecticut sales tax compliance because the wrong certificate or missing record can create a problem later during an audit or review.

Common Exemptions and Special Cases

Connecticut provides exemptions for a range of transactions. Common examples include:

• Purchases for resale, when supported by a valid resale certificate
• Certain sales to qualifying nonprofit organizations
• Some manufacturing-related purchases and equipment
• Certain agricultural items and uses
• Other exemptions listed in the Connecticut General Statutes and DRS guidance

If a sale is exempt, the seller should still document why no tax was charged. That usually means keeping exemption certificates, customer records, and transaction support in a way that can be reviewed later.

A common mistake is assuming that an item is exempt because the customer says it is. In practice, the seller is responsible for collecting and storing the right documentation.

Digital Goods and Software

Digital products deserve special attention because they are often overlooked during setup.

In Connecticut, digital goods and certain software transactions can be taxable. For example, electronically delivered or accessed software may be treated differently depending on the circumstances, and the tax rate can vary in some situations.

If your business sells downloads, subscriptions, SaaS products, digital templates, streaming access, or software licenses, review the tax treatment before launch. Checkout settings should be tested so the correct tax is applied by product type and customer location.

Remote Sellers and Marketplace Sales

Connecticut also applies sales tax rules to remote sellers and marketplace activity. If you sell through platforms such as Amazon, Etsy, eBay, Shopify, or other marketplace systems, you need to understand how facilitator rules affect your filing obligations.

A marketplace facilitator may be responsible for collecting and remitting tax on certain facilitated sales. However, sellers should not assume the marketplace handles every tax issue automatically. You still need to review your own reporting, exempt sales, and any separate filings required for direct sales outside the platform.

Remote sellers should also pay attention to Connecticut nexus rules. If your business has economic or physical connections to the state, you may need to register and collect tax even if you are not physically based in Connecticut.

Because nexus rules can change, businesses should confirm current thresholds and obligations directly with the Connecticut DRS before relying on an old rule or a competitor blog post.

Filing and Payment Basics

Once registered, businesses must file sales tax returns and remit collected tax on the schedule assigned by the state. Filing frequency may depend on the volume of sales and the type of business activity.

A strong filing process usually includes:

• Separating taxable and exempt sales in your records
• Reconciling payment processor reports with your bookkeeping
• Tracking returns, refunds, and discounts correctly
• Keeping copies of exemption certificates and supporting invoices
• Filing before the deadline every reporting period

If your business buys taxable items for use in Connecticut and no sales tax was charged at the time of purchase, use tax may apply. Use tax is often missed by new businesses because it can arise on equipment, supplies, software, and inventory purchases from out-of-state vendors.

Recordkeeping That Prevents Problems

Good recordkeeping is the easiest way to reduce sales tax stress.

At a minimum, keep:

• Sales reports by channel
• Invoices and receipts
• Exemption certificates
• Tax returns and payment confirmations
• Purchase records for business-use items
• Notes on special tax treatment for software, services, or resale transactions

A clean audit trail helps if the state asks questions later. It also makes it much easier to hand the business to a bookkeeper, CPA, or in-house finance team as you grow.

Common Mistakes New Businesses Make

New businesses often run into the same avoidable issues:

• Registering too late
• Forgetting to charge tax on taxable digital products
• Treating every service as exempt without checking the law
• Using the wrong exemption certificate
• Failing to separate taxable and exempt sales in accounting software
• Ignoring use tax on business purchases
• Missing filing deadlines after the first return

These problems are usually more expensive to fix after the fact than they would have been to prevent during setup.
