Maine sales tax rates 2026: Calculator, nexus, and due dates

Maine sales tax rates by city and county

Maine is one of the simplest states for sales tax rate calculation. The 5.5% state rate applies statewide for general retail sales, and no city, county, or special district adds a local sales tax on top. Every address in Maine has the same 5.5% general sales tax rate.

Maine does apply higher rates for specific categories: 8% on prepared food and alcoholic drinks sold in on-premises liquor-licensed establishments, 9% on short-term lodging rentals, and 10% on short-term automobile rentals. Adult-use cannabis is taxed at 14% as of January 1, 2026.

Because Maine is a destination-based state, you apply the rate based on where the customer receives the product. However, since there is only one general rate statewide, the destination address does not change the rate — it only determines that Maine sales tax applies. All returns are filed with Maine Revenue Services.

Maine nexus thresholds

Remote sellers and businesses with a physical presence in Maine are subject to nexus laws. You are required to register and collect sales tax if you trigger “nexus” through a physical presence in the state or by exceeding the economic threshold as a remote seller.

Maine economic nexus

You will trigger Maine economic nexus if you exceed either of the following thresholds in the current or previous calendar year:

• Sales threshold: $100,000 in gross revenue from sales delivered into Maine.
• Transaction threshold: None. Maine removed its 200-transaction threshold effective January 1, 2022. Nexus is now based solely on the $100,000 revenue threshold.

Marketplace facilitators are required to collect and remit tax on behalf of third-party sellers and are subject to the same $100,000 threshold. Once nexus is triggered, the seller must register with Maine Revenue Services and begin collecting tax.

Maine physical nexus

You have physical nexus (and must register from dollar one) if you have:

• Inventory: Storing goods in a warehouse, 3PL, or Amazon FBA fulfillment center in Maine.
• Personnel: Employees, contractors, sales reps, or agents conducting business in Maine.
• Property: Maintaining an office, storefront, distribution center, or other place of business in Maine.
• Affiliates: Sharing trademarks, trade names, or service marks with an in-state affiliate, or an affiliate performing activities that help maintain a market in Maine.

Maine sales tax permit registration

Once you trigger nexus, you must register with Maine Revenue Services before you can legally collect sales tax.

Operating without a permit after crossing the threshold exposes you to back taxes, penalties, and interest from the date nexus was established — not the date you registered.

1. Gather your information. You’ll need your FEIN, business structure details, estimated sales, and bank account information.
2. Submit your application. Register online through the Maine Tax Portal by selecting “Register a New Business” and completing the application. Paper forms are also available. There is no registration fee.
3. Note your effective date. Maine expects registration promptly upon crossing the $100,000 revenue threshold. If there’s a gap between crossing the threshold and registering, you may owe back taxes for that period.

If you have questions about your Maine registration or compliance history, TaxCloud’s U.S.-based support team typically responds within 2 hours and can review your setup directly.

Maine sales tax calculation rules

Maine’s calculation rules are among the simplest in the U.S. — a flat 5.5% rate statewide for general sales, no local taxes, and destination-based sourcing. The main compliance nuances involve the expanded taxability of digital streaming services effective January 1, 2026, and the category-specific higher rates for prepared food, lodging, and short-term auto rentals.

What is taxable in Maine?

Taxability in Maine is determined by how a product is classified under state law. Below is a high-level summary of how major categories are generally treated for 2026:

• Tangible personal property: Most physical goods — such as furniture, electronics, and standard retail items — are subject to the 5.5% state sales tax unless a specific exemption applies. Shipping charges are exempt when separately stated and delivered by common carrier directly to the customer. Handling charges are taxable.
• SaaS, software, and digital products: Maine taxes prewritten computer software, whether delivered electronically or on a physical medium, as tangible personal property. Custom software is not taxable. Access-only SaaS — where the customer accesses software remotely without a downloaded copy — is not taxable. Digital products (ebooks, music, movies) are taxable when permanent rights are granted to the purchaser. Effective January 1, 2026, digital audiovisual services and digital audio services — including subscription streaming platforms — are taxable at the 5.5% rate.
• Food & groceries: Maine exempts most unprepared food and food ingredients from sales tax. Prepared food sold in on-premises liquor-licensed establishments is taxable at 8%. Other prepared food is taxable at the standard 5.5% rate.
• Clothing: Clothing and footwear are taxable at the standard 5.5% rate.

What is tax exempt in Maine?

Below is a high-level summary of items that are generally tax-exempt in Maine:

• Essential exemptions: Maine provides specific exemptions for items such as prescription drugs, most unprepared food and food ingredients, durable medical equipment, breast pumps, and mobility-enhancing equipment for home or vehicle use (new exemption effective January 1, 2026).
• Additional exemptions: Sales for resale (with a valid resale certificate), manufacturing machinery and equipment, fuel and electricity used in manufacturing, certain agricultural supplies, and purchases by qualifying government agencies and nonprofit organizations with a Maine exemption certificate.

Maine sales tax return due dates and filing frequency

In Maine, sales tax returns are due on the 15th of the month following the reporting period — not the 20th used by most other states. Maine Revenue Services assigns filing frequency based on your average monthly tax liability.

Critical 2026 compliance notes:

• Service Provider Tax repealed (January 1, 2026): Maine repealed its separate Service Provider Tax and moved those services — including cable/satellite TV, telecommunications, fabrication services, and equipment rentals — into the standard 5.5% sales tax base. Businesses previously registered only for the Service Provider Tax must transition to Sales and Use Tax registration for periods beginning January 1, 2026.
• Digital streaming now taxable (January 1, 2026): Digital audiovisual works and digital audio works — including subscription streaming services like Netflix, Hulu, Spotify, Apple Music, and podcast/audiobook subscriptions — are now taxable at 5.5%. This is a new requirement that expands Maine’s tax base significantly for digital service providers.
• Adult-use cannabis rate increased (January 1, 2026): The sales tax rate on adult-use cannabis and adult-use cannabis products increased from 10% to 14%.
• Due date is the 15th, not the 20th: Maine’s filing deadline is earlier than most states. Sellers managing multi-state compliance should note this distinction to avoid late filing penalties.
• Zero-return requirement: If you are registered but had $0 in sales this period, you must still file. Failure to file results in a penalty of $25 or 10% of the tax due, whichever is greater.
• Weekend/holiday rule: If the 15th falls on a weekend or state holiday, your return is due the next business day.
• Electronic filing required: Maine Revenue Services Rule No. 104 requires electronic filing of sales and use tax returns through the Maine Tax Portal.
