Do you need to collect sales tax in Maine?

You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $100,000 in sales over previous or current calendar year. Maine used to trigger nexus at 200 transactions but removed that count in January 2022 — only the sales figure matters now.

The Maine rate

Maine has no local sales taxes — it is a single-rate jurisdiction statewide. Special rates apply to prepared food (8%), lodging (9%), short-term auto rental (10%), adult-use cannabis (10%), and service provider tax (6%).

Marketplace and direct sales

Marketplaces like Amazon collect Maine tax for you, but those sales don't count toward your own threshold. Direct sales on your own store you collect yourself.

Filing and zero returns

Once registered, Maine requires a return every assigned period even when you owe $0 — miss one and you can face penalties. MRS assigns frequency based on average monthly tax liability: monthly if $600+/month; quarterly if $100–$599/month; semiannual if under $100/month but over $50/year; annual if under $50/year.

When you can cancel

If your Maine returns are mostly $0, you may be over-registered. Canceling your Maine sales tax registration makes sense if your gross sales into Maine have been below $100,000 for two consecutive calendar years — you are legally entitled to cancel at that point and end your filing obligation. The main catch is the two-year wait: if you dropped below the threshold in Year 1, you must still file through the end of Year 2 before canceling, meaning up to two additional years of zero returns.

Where TrailingZero fits

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and maps your real nexus in Maine and flags whether you should register, keep filing, or cancel. 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.
