What is economic nexus in Maine?
Economic nexus means you can owe sales tax in Maine based purely on your sales volume there — no physical presence required. It traces to the 2018 South Dakota v. Wayfair decision. Maine's threshold took effect July 2018.
Today the threshold is $100,000 in sales, measured over previous or current calendar year.
The transaction-count history
Maine used to trigger nexus at 200 transactions but removed that count in January 2022 — only the sales figure matters now.
That matters because the 200-transaction prong used to catch very small sellers — 200 orders can be just a few thousand dollars of sales. If transactions were the only reason you registered in Maine, that trigger is gone.
What counts toward the threshold
gross sales of tangible personal property, electronically transferred products, and taxable services delivered into Maine; marketplace-facilitated sales excluded from individual seller's threshold if facilitator is collecting
Marketplace-facilitated sales do not count toward your own Maine threshold.
Where TrailingZero fits
TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and tracks your sales against Maine's threshold so you register only when you truly cross it — and deregister when you fall below. During any wind-down it can file the zero-dollar returns so nothing lapses — and you only pay for the states you genuinely keep. Run a free audit anytime; this page is free education either way.
