New York — nexus note

New York sales tax nexus and economic nexus threshold: a business with no New York physical presence is presumed to be a vendor when, in the immediately preceding four sales tax quarters, its gross receipts from tangible personal property delivered into New York exceed $500,000 AND it made more than 100 such sales into New York. Unlike most states, New York uses AND logic -- both thresholds must be met. Gross receipts include taxable and exempt tangible-personal-property sales without expense deductions, and sales transactions include invoices, sales slips, contracts, or other sale memoranda, including sales for resale. New York says marketplace sales should be included in the threshold calculation; after crossing, a remote seller files for registration within 30 days and begins collection 20 days later. Marketplace providers collect New York State and local sales tax on facilitated taxable tangible-personal-property sales delivered to New York, and marketplace sellers remain responsible for non-facilitated sales and taxable transactions outside the marketplace-provider rule.

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.
