Maine Sales Tax Guide

Do You Need to Collect and Remit Sales Tax in Maine? 

The short answer: probably—and more often than before.

Businesses operating in Maine are required to collect and remit sales tax if they sell tangible personal property, certain services, and specified digital products. And as of January 1, 2026, Maine significantly expanded what falls into that bucket.

The state eliminated its Service Provider Tax and consolidated many previously taxed (or untaxed) services into the standard sales and use tax system. In other words, if you provide services in Maine, it’s time to take a closer look at your taxability.

Not sure if your services are now taxable? That’s exactly the kind of gray area we help businesses navigate every day—reach out to SalesTaxSolutions.US for a quick review before it becomes a compliance issue.

Services Now Subject to Sales Tax

The following categories—previously handled in Service Provider Tax—are now generally taxed at the statewide rate of 5.5%:

• Cable and satellite television or radio services
• Fabrication services
• Telecommunications services
• Installation, maintenance or repair of telecommunications equipment
• Ancillary services
• Digital audiovisual and digital audio services (including streaming platforms like Netflix, Spotify, and audiobook/podcast subscriptions)

This shift aligns Maine with a broader national trend: if a service is routinely consumed like a product (especially digitally), it’s increasingly treated like one for tax purposes.

Some Exemptions Still Apply

Despite the expansion of taxable services, several key exemptions remain in place:

• Groceries
• Prescription drugs
• Prosthetic devices (e.g., crutches, wheelchairs)
• Feminine hygiene products
• Certain lodging exemptions (such as qualifying student housing)

That said, some exemptions are not automatic, especially when selling to nonprofits or government entities. Proper documentation (like exemption certificates) is still required, and failing to collect it can leave you on the hook for additional tax.

For a full breakdown of taxable and exempt items, refer to Maine Revenue Services’ official taxability guidance.

Resale and Exemption Certificates

Speaking of exemptions, Maine recently clarified its resale certificate rules—and they’re stricter than many businesses expect.

First, simply registering for a sales tax account does not entitle you to a resale certificate, even if you already work with a supplier. To qualify, a retailer must:

• Maintain an active sales tax account, and
• Report at least $3,000 in gross Maine sales within a 12-month period

Maine Revenue Services (MRS) reviews accounts annually and automatically issues resale certificates to businesses that meet these criteria.

Until then, you are generally required to pay sales tax on purchases intended for resale. However, the state allows you to recover that tax. You can claim a credit by reporting the amount paid on resale purchases on your sales tax return under: “Credit for Sales Tax Paid on Goods Resold.”

This process is legitimate, but it can create short-term cash flow strain, particularly for wholesalers, drop shippers, and new retailers. In short, plan ahead, and don’t assume resale treatment applies on day one.

As for exemption certificates, Maine has a whole host of available options depending upon business activity.

Do You Have Sales Tax Nexus in Maine? 

Nexus determines whether you’re required to collect sales tax—and Maine enforces it with both traditional and modern rules.

There are two primary types of nexus to consider: physical and economic.

Physical Sales Tax Nexus

You have physical nexus if your business has a tangible presence in Maine, including: 

• An office, retail location, warehouse, or stored inventory
• Employees or representatives operating in the state
• Installation, repair, or maintenance services performed in Maine
• Ownership or leasing of property

With services now more broadly taxable, service providers performing work in Maine are more likely to trigger nexus than before.

Economic Sales Tax Nexus

Economic nexus is triggered by your level of activity in the state. In Maine, you have economic nexus if you exceed: 

• More than $100,000 of gross sales to Maine customers in the current or previous calendar year

This includes both taxable and non-taxable sales.

Once you cross the threshold, you must register with Maine Revenue Services and begin collecting sales tax on the first day of the month that begins at least 30 days after crossing the threshold.

For example, if you exceed the threshold on May 15, you must begin collecting sales tax by July 1.

This delayed effective date provides a short runway—but not much. Monitoring your sales in real time is critical to staying compliant. Contact SalesTaxSolutions.US today for fast, accurate nexus determinations, so you don’t miss a sales tax collection window.

Are Marketplace Facilitators Required to Collect and Remit Sales Tax in Maine? 

Yes.

Marketplace facilitators are required to collect and remit sales tax if they exceed $100,000 in gross Maine sales. These sales include the facilitator’s own direct sales, transactions facilitated on behalf of third-party sellers.

What This Means for Sellers

If you sell exclusively through a marketplace:

• The facilitator is generally responsible for collecting and remitting sales tax
• You are typically not liable for sales tax on those transactions

But what if you are a marketplace seller and also make direct sales, such as on your website? In that case, only count your direct sales when determining nexus. Marketplace sales are excluded from your threshold calculation. That said, recordkeeping is critical. In the event of an audit, you’ll need to clearly distinguish between marketplace-facilitated sales and direct (self-fulfilled) sales.

Common Marketplace Facilitators

• Amazon 
• eBay 
• Shopify Shop App
• Etsy    
• Walmart Marketplace

When Are Sales Tax Returns Due in Maine? 

Maine assigns filing frequencies based on your average tax liability:

• Monthly
• Quarterly
• Semi-annual
• Annual

All returns are due on the 15th day of the month following the reporting period. If the due date falls on a weekend or state holiday, it shifts to the next business day.
