Do you have sales tax nexus in Maine?

Good news! You only have to begin thinking about Maine sales tax if you have sales tax nexus in Maine.

“Sales tax nexus” is just a fancy way of saying “significant presence” in a state.

Maine considers a seller to have sales tax nexus in the state if you have any of the following in the state:

  • A store, office, warehouse, repair facility or other place of business
  • An employee, salesperson, contractor or other representative
  • Economic nexus (i.e. your sales or transactions into the state mean you are subject to the state’s economic nexus rule)

Do you have economic nexus in Maine?

Effective July 1, 2018, Maine considers vendors who make more than $100,000 in sales annually in the state or more than 200 transactions in the state in the previous or current calendar year to have economic nexus. This means the state considers these vendors obligated to collect sales tax from buyers in the state. You can read Maine’s economic nexus guidance for sellers here and you can read more about economic nexus in every state here.

Is what you’re selling even taxable?

You’ve probably read this far because you realized you have sales tax nexus in Maine. Your next step is to determine if what you’re selling is even taxable.

Services in Maine are generally not taxable. So if you’re a freelance writer or a plumber, you’re in luck and you don’t have to worry about sales tax. But watch out – if the service you provide includes creating or manufacturing a product, you may have to deal with the sales tax on products.

Tangible products are taxable in Maine, with a few exceptions, including grocery staples, some medicines and medical equipment as well as some items associated with commerce. For more guidance, click here for more information around Maine notices.

So if you sell furniture, then charge sales tax to your Maine customers.

But if you’re an electrician, don’t charge sales tax to your Maine customers.

If you have sales tax nexus in Maine and your products are taxable, your next step is to register for a sales tax permit.

How to Register for a Sales Tax Permit in Maine

Sellers with sales tax nexus in Maine must apply for a Maine sales tax permit.

Don’t skip this step! Many states consider it unlawful to collect sales tax in their name without a permit. Go here for more on how to register for a sales tax permit in Maine.

How to Collect Sales Tax in Maine

So you’ve determined that you have sales tax nexus in Maine and what you’re selling is taxable. And you’re all set and registered for your Maine sales tax permit.

The next step is to determine how much sales tax to collect.

Fortunately, collecting sales tax in Maine is fairly simple. The state sales tax rate is 5.5% and Maine doesn’t have local rates. So whether you live in Maine or outside Maine but have nexus and sell to a customer there, you would charge your customer the 5.5% sales tax rate on most transactions.

That said, some items - like prepared food - are taxed differently. In Maine, prepared food is taxed at an 8% rate. Find out more about these Maine sales tax exceptions here.

Should you collect sales tax on shipping charges in Maine?

Not usually. As long as you separately state the shipping charges on your bill to your customer, you do not have to charge sales tax on shipping.

But if you include shipping in the price of the product you sell the customer, then shipping is considered part of the taxable transaction and Maine declares that you must collect sales tax on shipping.
