The Connecticut sales tax on SaaS is 1%. The state classifies software-as-a-service as a “computer and data processing service” rather than tangible property or a digital good, which puts it well below the standard 6.35% sales tax rate. That reduced rate applies whether the buyer is a business or an individual, and it has been in place since July 1, 2001.1Justia Law. Connecticut Code Title 12 – Section 12-408 – The Sales Tax
Why SaaS Falls Under the 1% Rate
Conn. Gen. Stat. ยง 12-407(a)(37)(A) defines taxable “services” to include computer and data processing services, a category that covers time-sharing, programming, code writing, feasibility studies, and software installation and implementation.2Justia Law. Connecticut Code Title 12 – Section 12-407 – Definitions A subscription that lets the customer use software hosted on a vendor’s servers, without ever downloading or owning a copy, fits within this definition.
The Department of Revenue Services looks at the primary purpose of the transaction. If the customer is paying for software functionality delivered through a browser, that’s a data processing service, and it doesn’t matter where the vendor’s servers physically sit. PS 2006(8), the agency’s main policy statement on computer-related services, confirms that remote access to software falls within the category as long as the customer never takes title to the underlying code.3Connecticut State Department of Revenue Services.

Downloaded Software and Digital Goods Are Different
The 1% rate is easy to miscount if you assume every software-adjacent purchase gets the same treatment. Connecticut applies three different rates depending on what the customer receives.
Canned Software Delivered Electronically
Downloaded prewritten software gets split treatment. If a business buys canned software electronically for its own business use, the sale is taxed at 1% as a computer and data processing service. If the same software is bought for personal use, it’s taxed at 6.35%.4Connecticut Department of Revenue Services. SN 2019(8) – Sales and Use Taxes on Digital Goods and Canned or Prewritten Software Canned software delivered on a physical medium like a USB drive is always taxed at 6.35%, regardless of who buys it.5Connecticut State Department of Revenue Services. Sales and Use Tax Information
Digital Goods
Digital goods like e-books, music, videos, and ringtones that are electronically accessed or transferred are taxed at the full 6.35% rate. The statute specifically excludes digital goods from the definition of computer and data processing services, so they don’t qualify for the 1% rate.2Justia Law. Connecticut Code Title 12 – Section 12-407 – Definitions This matters for vendors who bundle content, like stock photos or video libraries, with software tools. If the primary purpose of the subscription is content delivery rather than software functionality, the 6.35% rate may apply.
When Out-of-State SaaS Vendors Must Collect
A SaaS company with no office, employees, or equipment in Connecticut can still be required to collect and remit tax if it does enough business with Connecticut customers. Following the U.S. Supreme Court’s 2018 decision in South Dakota v. Wayfair, Connecticut adopted economic nexus rules for remote sellers. A vendor triggers a collection obligation if, during the preceding twelve-month period, it has either $100,000 or more in gross receipts from Connecticut sales or 200 or more separate transactions with Connecticut buyers.
Once either threshold is crossed, the vendor must register with the Department of Revenue Services and begin collecting the applicable tax. The obligation is forward-looking. Crossing the threshold starts the collection duty going forward, but you generally don’t owe tax on sales made before you had nexus.
Use Tax When the Vendor Doesn’t Charge It
A Connecticut business that buys a SaaS subscription from an out-of-state vendor that doesn’t charge Connecticut tax still owes the tax. Connecticut imposes a use tax at the same rate as the sales tax, and the buyer is responsible for self-reporting and remitting it.5Connecticut State Department of Revenue Services. Sales and Use Tax Information For a computer and data processing service, that’s 1%. For canned software bought for personal use, it’s 6.35%.
Businesses report use tax on their regular sales and use tax return through the myconneCT portal. It comes up most often with smaller SaaS vendors based outside the U.S. or early-stage companies that haven’t yet registered in Connecticut. If your vendor isn’t charging Connecticut tax, the obligation shifts to you as the buyer.
Registering and Filing if You Have to Collect
Before collecting Connecticut sales tax, a vendor must register with the DRS. New businesses complete Form REG-1, the Business Taxes Registration Application, electronically through the myconneCT portal.6Connecticut State Department of Revenue Services. Applications/Registration Applications There’s a $100 application fee.
The form asks for the business’s Federal Employer Identification Number, legal entity name, headquarters address, contact information for officers or principals, and the date taxable sales will begin. You’ll also need to describe the nature of your services so the DRS can confirm you fall under the computer and data processing category. Once approved, the state issues a tax registration number for all future filings.7Connecticut State Department of Revenue Services. Register Your Business
All filing and payment then happens through the same myconneCT portal.8Connecticut State Department of Revenue Services. myconneCT Filing frequency depends on your sales volume. Higher-volume businesses file monthly; smaller ones file quarterly or annually. The DRS assigns your frequency at registration and can change it if your volume shifts.
Resale and Other Exemptions
If a Connecticut customer buys SaaS intending to resell it unaltered to an end user, the sale may qualify for a resale exemption. The buyer must give the vendor a valid resale certificate at the time of purchase. Without that certificate on file, the vendor is expected to collect tax. Vendors should confirm that any resale certificate they accept is being used for a legitimate resale purpose, not to avoid tax on software the buyer intends to use internally.
Government agencies and certain nonprofit organizations may also be exempt, but exemptions are narrow and require proper documentation. When an exemption is uncertain, the safer path is to collect the tax and let the buyer apply to the DRS for a refund, rather than risk an undercharge falling on the vendor at audit.
