Do I charge Connecticut sales tax on Shopify orders in 2026?

For 2026, Shopify sellers charge Connecticut sales tax once their Shopify-store sales into Connecticut cross $100,000 in gross sales OR 200 transactions. From that point, charge the 6.35% state rate plus any applicable local rate at the buyer's ship-to address. Whether facilitator-collected orders (Shopify Markets Pro, Amazon, Etsy) also count toward the Connecticut threshold is a per-state rule — some states let you exclude them, others require them in the count even though the marketplace remits — so verify before excluding them.

Is Shopify a marketplace facilitator in Connecticut?

Shopify's core storefront product is not a marketplace facilitator in any state — with a standalone Shopify store you are the seller of record and remain responsible for Connecticut registration, collection, and remittance. Shopify Markets Pro, by contrast, operates as a marketplace facilitator in many states; verify Connecticut's current treatment before excluding Markets Pro orders from your nexus count.

Does Shopify handle Connecticut sales tax automatically?

Shopify can calculate Connecticut rates once you enable the state in Settings → Taxes and duties. Shopify does NOT register you with Connecticut or file returns — those remain your responsibility.

When do Shopify sellers need to register in Connecticut?

When you cross $100,000 in gross sales OR 200 transactions in Connecticut revenue from your Shopify store. Whether marketplace-facilitated orders (Amazon, Etsy, Shopify Markets Pro) count toward that same Connecticut figure varies by state — confirm Connecticut's treatment with the Connecticut Department of Revenue rather than assuming they are excluded.

Is Shopify Tax worth it for Connecticut?

Connecticut has no local rate add-ons — the 6.35% state rate applies at every Connecticut delivery address — so Shopify's built-in calculator is usually sufficient here. Shopify Tax mainly buys you local-jurisdiction accuracy; it does not register you or file your returns.

If your Shopify business sells $100,000 or 200 transactions into Connecticut in a calendar year, you have economic nexus and must register, collect, and remit Connecticut sales tax.

Shopify sales tax in Connecticut

Connecticut applies a 6.35% state rate to most physical goods shipped from a Shopify store. Shopify's built-in tax engine can source destination rates for CT once you enable the state at Settings → Taxes and duties → United States. There is no local add-on to reconcile here, so the built-in calculator is usually enough.

Shopify does not register with the Connecticut Department of Revenue on your behalf and does not file returns. Those duties still fall to you once you cross $100,000 or 200 transactions inCT-destined sales.

When Shopify sellers typically trigger nexus

Your CT-destined store revenue crosses $100,000 or 200 transactions. Only the Connecticut slice of your sales is tested — total US revenue is not the trigger, so a store well past $1M nationally can still be below threshold here, and a niche store concentrated in Connecticut can be over it.
Running paid ads targeting Connecticut customers specifically.
Selling high-ticket items: even a handful of $10K orders to Connecticut can cross dollar thresholds fast.
Using a 3PL warehouse in Connecticut (physical nexus regardless of revenue).

Shopify-specific quirks in Connecticut

If you use Shopify Shipping, Shopify's calculated shipping rates include tax for many states. Verify your CT rules on whether shipping is taxable — some states tax shipping charges if the product itself is taxable.
Discounts: line-item and order-level discounts are applied before tax in Shopify. Coupons and gift cards need to be handled carefully in Connecticut — check whether the state reduces the taxable base or keeps it on the pre-discount total.
Shopify Markets and regional fulfillment can create additional nexus surprises if the inventory lives in a Connecticut warehouse.

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.
