Maine Sales Tax FAQ

Maine Sales Tax FAQ 


By now, you may have already contacted the Maine Revenue Services and applied for a Maine sales tax permit. 

Once you have a license to collect and remit sales taxes in Maine, you will probably be asking yourself two questions: 

  • When do I charge a sales tax in Maine?
  • What goods and services are subject to sales taxes in Maine? 

We are going to go over some common questions that our clients have asked. We believe these questions will help you appreciate the nuances of taxable goods so you can be confident in fulfilling your tax obligations. 

Let’s start with the first question…



What goods and services are considered taxable in Maine?

The following items are all taxable in the state of Maine: 

  • Sales of tangible goods at retail.
  • Repairs or alterations of tangible personal property.
  • Property rentals, leases, or licenses [e.g. commercial, mini-warehouse]
  • Selling service warranty contracts.
  • Short-term rentals for living accommodations (e.g. motel/hotel, beach houses, condos, timeshares, vacation homes, or RV homes).
  • Charges for admission to any place of amusement, sport, or recreation.
  • Manufacturing or producing goods for retail sales.
  • Operating vending machines or amusement rides.
  • Services are mostly exempted


The bottom line is …

Your business must pay taxes on sales of any non-exempt goods, and some taxable services.




Let’s now review some of our clients’ frequently asked questions:

  • Is Maine an Origin or Destination sales tax State?
  • What creates a sales tax nexus in Maine?
  • What is the economic threshold in Maine?
  • Does Amazon have fulfillment centers in Maine?
  • Does Maine have a Click-Through Nexus?

To best understand your tax obligations, new businesses need to consider how they are doing business and the type of relationships they have with buyers and any third parties to their transactions. 

 Let’s discuss some questions that will help you understand the nature of your small business and the subsequent tax implications.   


Is Maine an origin or destination-based sales tax state?

Maine is a destination-based sales tax state, which simply means you charge sales tax based on the location of the purchaser rather than that of the seller. Maine keeps it fairly simple compared to other states by not permitting cities or localities to bump the rate, which means only one rate state-wide. 


 Protip: Charge the customer tax based on their location.


What creates a tax nexus with the state of Maine?  

Having nexus, also known as "sufficient business presence,” with Maine means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in Maine because you created a sales tax Nexus.

Even if your business maintains its main headquarters in another state, you may still have to charge and pay sales tax to the Maine Revenue Services even if you never step foot in Maine.   

So, how do you create sales tax nexus in Maine?


Sales Tax Nexus in Maine


A business establishes a nexus in Maine by:

  • having a business location in Maine;
  • having property stored in Maine;
  • employing any person in Maine;
  • contracting with a salesperson or other agent in Maine;
  • leasing equipment used in Maine;
  • performing services in Maine;
  • licensing the use of intangible property in Maine, or transporting property in Maine using the taxpayer’s vehicles.

Let’s talk a bit more specifically about where your goods are stored such as in the instance of an Amazon warehouse. 



Does Amazon have fulfillment centers in Maine?

No, Maine has no distribution centers at this time.

This information is relevant for our customers who sell products on Amazon or are recognized as Amazon FBA (Fulfillment by Amazon) sellers. When Amazon stores products in one of its fulfillment centers in any state including, it triggers a sales tax requirement. 



Does Maine have economic nexus?

Yes! Maine now has an economic nexus law. What does this mean? As of July 1st, 2018 remote sellers are liable to pay sales tax beyond a certain threshold. This means even businesses without a physical presence or traditional nexus can be required to register for, collect, and pay sales taxes.

The threshold for registering is having a cumulative gross revenue of over $100,000 in sales to Maine purchasers or 200 separate transactions.

For  more information see the Maine’s remote sellers page.



Does Maine have click-through nexus?

Yes! Maine has click-through nexus for remote sellers. This means if your business is involved in affiliate marketing sales to Maine purchasers, you may be liable to pay sales tax even if you aren’t located in the state of Maine. 



Is Maine a streamlined sales tax state?

No, Maine is not at this time a member of the SSP. However there has been legislative progress towards that end so it may be joining soon!

Collecting Sales Tax in Maine

Collecting Sales Tax in Maine


By now you know if you are a business that has established a nexus with Maine. So you have an understanding about whether, or when, you are required to collect sales tax. Knowing this is just half the battle! Now, we are going to help you with the next half of the battle: how to navigate the process of collecting taxes.

Let’s review some common questions our clients have asked regarding their Maine Sales Tax obligations. 

  • How do I collect Maine Sales Tax?
  • Who is eligible for Maine Sales Tax exemptions?
  • What should I do if my customer is exempt from sales tax in Maine?
  • What happens if I lose a Maine nontaxable transaction certificate? 

After reading this, you will be better equipped to determine when --and when not-- to collect sales tax in Maine.



How do I collect Maine sales tax?

Because Maine is a destination-based sales tax state with no localities, your business charges a single flat rate throughout the state. You may incorporate or part out the tax into the final price at your discretion, but you must post notice either on the sales slip or on your premise that sales tax is incorporated. 



What are the current Maine sales tax rates?   

Maine’s state-wide sales tax rate is 5.5% for tangible goods and 6% for their Service Provider Tax at the time of this article’s writing. However, since sales tax rates may change, we shall refer you to check out the Maine Revenue Services tax rate lookup page. Any change will be reflected on that page.

It always helps to be accurate and up to date with this type of information! :) 



What is exempt from Maine sales tax?

Sales tax exemptions

Here is a sample list of exemptions: 

  • Purchases for resale
  • Everyday clothing items
  • Medical supplies
  • Groceries 

Maine has far too many exempt items to list here, but they go into greater detail on page 7 of this PDF.



Who are eligible for Maine sales tax exemptions?

At this point, you should know what products are exempt from sales tax in Maine. You also want to know who may be exempt. 

Under Maine law, the type of buyer or the way the goods will be used can qualify can buyer for a sales tax exemption. A good example of this is a merchant purchasing goods for resale, aka a wholesaler.

Other common examples of an exempt buyer may include:

  • Government agencies
  • Non-profit organizations
  • Religious groups
  • Out-of-state buyers (should their business not have nexus in their home state).

Note that a non-profit or contractor status doesn’t necessarily immediately confer tax exempt status. Maine keeps a list of tax-exempt organizations..



What should I do if my customer is exempt from sales tax in Maine?

Purchasers who are tax exempt must have completed an exemption certificate and must present their completed exemption certificate at the time of purchase. It is then incumbent upon the seller to hold on to this exemption certificate. Failure to do so may leave you unable to justify tax exempt sales.

Maine provides a website to determine whether an exemption certificate is valid. Note that determining the validity via the website doesn’t reduce the requirement to hold on to the certificate for bookkeeping purposes.



What happens if I lose a Maine Sales Tax exemption certificate?

Hmm... Obviously this issue is best to be avoided! Imagine finding out you’ll be audited and discovering you cannot produce an exemption certificate for a buyer! That nightmare scenario would mean you could be held liable to pay all taxes on behalf of the buyer. This is a bad scene and can be avoided by taking proper care with your paperwork… which happens to be one of our specialties! :) 



Does Maine have a sales tax holiday?

Negative, the tax man never sleeps in Maine. 





We have now covered who you need to collect sales taxes from, how to determine whether goods for sale are deemed taxable, what goods and services fall under tax exemptions, who is eligible for tax exemption certificates, and, finally, the process of collecting sales tax in Maine state. 

Now that we’re this far down the rabbit hole there’s only one thing we need to learn about next… how to pay the piper!
