Selling into Jefferson County: New York rules
What's taxable: At the state level, SaaS is taxable, clothing is partly taxable, groceries are exempt and digital goods are exempt.
Economic nexus: New York has economic nexus only when you exceed both $500,000 in receipts from sales of tangible personal property delivered into the state and more than 100 sales transactions, measured over the preceding four sales-tax quarters. Because New York uses an "and" test, crossing just one threshold does not create nexus.
Filing: New York assigns annual, quarterly, or part-quarterly (monthly) filing based on taxable receipts. Most businesses file quarterly.
Registration, exemptions, penalties and marketplace rules are in the New York sales tax guide.
