New Jersey — nexus note

New Jersey sales tax nexus and economic nexus threshold: since November 1, 2018, remote sellers must register, collect, and remit New Jersey Sales Tax when current- or prior-calendar-year gross revenue from sales of tangible personal property, specified digital products, or taxable services delivered into New Jersey exceeds $100,000 OR those sales reach 200 or more separate transactions. New Jersey includes nontaxable retail sales of tangible personal property and specified digital products in the $100,000 gross-revenue test, but remote sellers making only resale sales or only nontaxable retail sales are not required to register on that basis. Marketplace facilitators collect New Jersey Sales Tax on marketplace transactions regardless of whether the marketplace seller is above or below the threshold; an over-threshold marketplace-only seller may register and request non-reporting status.

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.
