Simple statewide rate, a few sharp edges
Growing your business into Maine? Once you hit $100,000 in sales, you've triggered nexus and it's time to register. Maine keeps things relatively simple with a flat 5.5% statewide rate and no local taxes to juggle — but its unique Service Provider Tax and higher rates on prepared food and lodging can catch businesses off guard.
The quick version: $100,000 in revenue triggers nexus. SaaS remains exempt, but digital audio and video became taxable in 2026.
This guide covers Maine's economic nexus requirements, filing obligations, and the specific quirks that can catch businesses off guard.
Maine sales tax rate table
| Field | Value |
|---|---|
| State base rate | 5.5% |
| Average combined rate (state + local) | 5.50% |
| Local add-on range | None |
| Maximum possible combined rate | 5.5% |
| Rates vary by county / city | No |
| Destination-based or origin-based | Destination-based |
There are no local sales taxes anywhere in Maine. Remote sellers and in-state businesses alike charge the flat 5.5% state rate on taxable sales — you won't need to track multiple jurisdictions.
$100,000 — revenue only, since January 2022
You must register once your gross sales pass $100,000 in the current or previous calendar year. Maine eliminated its transaction count threshold in January 2022.
- The $100,000 counts all your Maine sales, not just taxable ones.
- Sales through marketplace facilitators count toward your threshold, but if the marketplace collects and sends tax on your behalf, you don't need to register separately for those transactions.
SaaS is exempt — digital audio and video are now taxable
Maine draws a clear line: traditional SaaS is exempt, but digital audiovisual and audio content became taxable in 2026.
| Product / service | Tax treatment |
|---|---|
| SaaS (B2B and B2C) | Exempt |
| Streaming / subscription software access | Exempt when used for business/productivity |
| Downloaded software (permanent license) | Taxable at 5.5% |
| E-books | Exempt |
| Music downloads & streaming | Taxable at 5.5%, since 2026 |
| Video downloads & streaming | Taxable at 5.5%, since 2026 |
| Digital images & fonts | Exempt |
| Cloud storage / data processing | Exempt |
SaaS remains safe. Digital entertainment is now taxable. If you're unsure whether your service qualifies as SaaS or falls into the new digital content category, Maine Revenue Services hasn't issued extensive guidance yet.
Product taxability in Maine
| Product category | Tax treatment |
|---|---|
| Groceries & unprepared food | Exempt |
| Prepared food & restaurant meals | Taxable at 8% (higher than standard rate) |
| Candy & soft drinks | Exempt (treated as groceries) |

Prepared food premium: Maine's 8% rate on prepared food is higher than standard. Lodging is taxed even higher, at 9%. Candy exemption: unlike most states, Maine exempts candy and soft drinks.
Maine does not currently offer any sales tax holidays
Maine's approach to sales tax relief focuses on broad exemptions for categories like groceries and prescription drugs, rather than temporary holiday periods. You'll collect the standard 5.5% rate year-round (or 8% on prepared food and 9% on lodging).
Filing and registration
Registration
Maine Revenue Services (MRS) administers sales tax. Register through the Maine Tax Portal at no cost. Processing takes 5 to 10 business days, but you can start collecting as soon as you submit.
Filing frequencies
| Frequency | Assigned when… |
|---|---|
| Monthly | Tax liability exceeds $24,000 per year |
| Quarterly | Tax liability $1,200–$24,000 per year |
| Annual | Tax liability under $1,200 per year |
Returns and payments are due on the 15th of the month following the reporting period.
Large-filer rules
Businesses with monthly tax liability exceeding $100,000 must prepay by the 25th of the current month, then file the actual return by the 15th of the following month.
Penalties and interest
- Late filing: 10% of the tax due
- Late payment: 10% of the unpaid tax
- Interest: 8% annually
No vendor discount: you send the full amount, with no reward for filing on time.

Not home-rule — and not an SST member
Maine has no home-rule jurisdictions for sales tax. You register once with Maine Revenue Services and you're covered statewide.
Maine is not a member of the Streamlined Sales Tax agreement in any capacity. You won't benefit from SST's simplified registration when dealing with Maine — but the state's lack of local taxes and straightforward system means compliance is already less complex than many other states.
Voluntary Disclosure Agreement (VDA)
Maine offers a formal VDA program administered directly by MRS, plus a path through the MTC.
Lookback & relief
Without a VDA, Maine can assess up to six years of unpaid tax. The VDA program typically limits this to three years. Penalties are waived entirely; interest is owed in full.
Eligibility & process
You must not have been contacted by MRS regarding sales tax liability. Apply anonymously through the MTC or directly. Expect 60 to 90 days from application to final agreement.
Consider a VDA if you have significant unreported Maine sales over multiple years — you can wipe out older back taxes completely by coming forward voluntarily.
Audit risk in Maine
Maine Revenue Services is methodical but not aggressive. Audits tend to focus on compliance gaps rather than squeezing every possible dollar.
Common audit triggers
- High volume of exempt sales (especially resale certificates)
- Inconsistent filing patterns or late returns
- Businesses in lodging, prepared food, or telecom (higher rates apply)
- Misclassification of digital goods or streaming services post-2026
- Service Provider Tax (SPT) confusion — many businesses miss this separate obligation
Statute of limitations
Maine can assess tax for three years from the return due date; no statute for fraud or failure to file.
Recent changes & quirky rules
Digital audiovisual and audio works are now taxable. If you sell streaming or subscription content, you may now owe Maine sales tax — even though SaaS remains exempt.
A separate tax on telecommunications, fabrication, and some business services, outside the normal sales tax system. This catches many service businesses off guard.
8% on restaurant meals, 9% on short-term lodging — both higher than the standard 5.5% rate.
Exemptions & resale certificates
Resale certificates
Maine issues an official Resale Certificate (Form ST-RES-1). Maine accepts the SST Multistate Tax Commission Certificate. Certificates are blanket and don't expire but should be updated if business information changes.
Seller liability
Sellers who accept a resale certificate in good faith are generally protected from liability if it's later deemed invalid.
Common exemptions
- Resale / wholesale — yes
- Manufacturing equipment — yes, direct use in production
- Agriculture — yes, farm equipment, seed, feed
- Nonprofits — limited; must apply
- Government — yes, federal, state, local
- Medical — yes, prescription drugs and prosthetics
Maine does not currently offer direct pay permits.
Your next steps for Maine compliance
Maine's straightforward approach makes it one of the easier states to manage. But with the 2026 digital goods expansion, businesses selling streaming content or digital subscriptions have new obligations to address.
- Check your nexus status. If you're close to $100,000, plan for registration now.
- Audit your product taxability. The line between exempt SaaS and taxable digital content isn't always obvious.
- Consider a VDA if you're behind. It can limit your lookback to three years and eliminate penalties entirely.
- Don't overlook the Service Provider Tax if your business provides telecommunications, fabrication, or certain business services.
