Does Connecticut charge sales tax on SaaS in 2026?

Yes. Connecticut charges sales tax on SaaS in 2026, but the rate depends on the buyer: 1% when a business purchases the subscription for business use, and 6.35% when canned software is electronically accessed or transferred for personal use. Connecticut has no local sales tax, so nothing is added on top. Confirm your product's classification with the Connecticut Department of Revenue Services before invoicing.

What is the sales tax rate on SaaS in Connecticut?

1% when the subscription is purchased by a business for business use. The same canned software electronically accessed or transferred for personal use is taxable at the 6.35% general rate instead. Connecticut has no local sales tax, so the state rate is the entire rate — there is nothing to add by city or county.

Does Connecticut tax business-use and personal-use software differently?

Yes, and the gap is large. Business-use SaaS and other computer and data processing services are taxed at 1%; canned software electronically accessed or transferred for personal use is taxed at 6.35%. On a $2,000-per-month subscription that is $20 versus $127 a month, so record whether each customer is buying for business use and keep documentation supporting the 1% rate.

Does shipping physical media change the Connecticut SaaS rate?

Yes. Connecticut DRS says canned software transferred with tangible personal property is taxable at 6.35% "in all cases." Bundling a disc, dongle, or hardware appliance with the subscription can move the charge off the 1% computer-and-data-processing rate onto the general rate, so itemize deliberately and confirm the treatment with DRS before invoicing.

When does a remote SaaS company need to register in Connecticut?

Connecticut's remote-seller test is $100,000 in gross sales OR 200 transactions, and both prongs must be met. Because Connecticut taxes most business-use SaaS at 1% rather than exempting it, a remote SaaS seller that crosses the threshold generally registers and collects rather than filing zero returns. Confirm your product's classification with the Connecticut Department of Revenue Services.

Use this Connecticut SaaS sales tax guide to check 2026software subscription taxability, taxable vs. non-taxable SaaS treatment, bundled services, and when the $100,000 or 200 transactions economic nexus threshold creates registration and filing duties. If SaaS is not taxable in Connecticut, crossing the threshold may still mean registering or filing zero-tax returns rather than collecting tax.

Is SaaS taxable in Connecticut?

SaaS taxability varies wildly by state. Connecticut's general sales tax rate is 6.35%, but whether software-as-a-service is subject to that rate depends on the state's definition of “taxable service” or “canned software” and on whether it's delivered to an in-state user.

Regardless of SaaS taxability, the economic nexus threshold of $100,000 or 200 transactions applies. If you exceed it on subscription revenue, you register; from there the question becomes what you tax, not whether.

Connecticut SaaS taxability snapshot

As of August 2026, Connecticut taxes software-as-a-service bought by a business for business use at 1% — not at the 6.35% general rate. The same subscription sold for personal use is taxed at 6.35%.

Connecticut reaches SaaS through its enumerated “computer and data processing services” category under Conn. Gen. Stat. §12-407. DRS describes that category as including “charges for online access to computer services, services to create, develop, host or maintain all or part of a website, and canned software electronically accessed or transferred, without any tangible personal property, purchased by a business for business use.” DRS lists the rate on computer and data processing services separately from the general rate: “1% Sale of computer and data processing services.”

Are SaaS subscription renewals taxable in Connecticut? Yes. Connecticut taxes the gross receipts from rendering an enumerated service, so a renewal invoice is a charge for the same taxable service as the original term and is taxed on the same basis at the same rate. There is no first-term-only treatment and no renewal exemption — a monthly, annual, or multi-year renewal of business-use SaaS is taxable at 1%.

The three rates worth separating:

1% — SaaS and other computer and data processing services, including canned software electronically accessed with no tangible medium, purchased by a business for business use.
6.35% — canned software electronically accessed or transferred for personal use. Selling the same product to consumers and to businesses means two different rates on the same SKU.
6.35% — canned software transferred with tangible personal property, which DRS says is taxable at the general rate “in all cases.” Shipping a disc, dongle, or appliance alongside the subscription moves the whole charge off the 1% rate.

Worked example: a $2,000-per-month Connecticut business-use SaaS subscription is taxed at 1% — $20 per month, $240 a year. The identical subscription sold to an individual for personal use is taxed at 6.35% — $127 per month, $1,524 a year. The business/personal distinction is worth 6.35× on the same invoice, so record which one each customer is.

Charges for Internet access services are not taxable in Connecticut, and Connecticut has no local sales tax, so the 1% or 6.35% state rate is the whole rate — there is nothing to add by city or county.

Separately from taxability, the Connecticut remote-seller threshold is $100,000 or 200 transactions, so a remote SaaS seller tests both the dollar and the transaction prong before registering.

Practical steps for SaaS companies

Track Connecticut-sourced ARR (use billing country or IP geolocation).
Determine taxability: consult a CPA or use an automated service that maintains taxability rules by state.
Check whether registration is required once you cross the threshold even if your SaaS is currently non-taxable. States differ: some count nontaxable sales in the threshold test and still want a registration on file, others exempt sellers whose Connecticut sales are entirely nontaxable. Ask the DOR rather than assuming either way.
Integrate tax calculation into your billing platform (Stripe Tax, Quaderno, Chargebee with Avalara).

SaaS-specific traps to avoid in Connecticut

Treating SaaS and “canned software” the same way. Many states distinguish between cloud-hosted SaaS and prepackaged downloaded software, with different tax treatments. Check Connecticut's specific definitions before assuming your product falls in either bucket.
Bundling non-taxable SaaS with taxable services (training, consulting, hosting). Across US states, bundle-pricing can make the whole charge taxable when the taxable component isn't separately stated — the exact bundling test is set state by state, so verify Connecticut’s before you design the invoice.
Ignoring use-tax obligations. If your customers are in Connecticut and your SaaS isn't taxable there, the customer may still owe use tax — a detail that can trip up B2B SaaS during audits.

Connecticut nexus note

Economic nexus in Connecticut requires BOTH more than $100,000 in gross sales AND more than 200 separate transactions delivered into Connecticut in the prior year. Both thresholds must be met.
