Why do you need to collect sales tax in Maine?

If you’re selling goods and services in Maine then sales tax might apply! To determine your obligation, you need to understand “nexus,” which ties businesses to states for tax purposes.

Two types of nexus exist:

  1. Physical Nexus: Having a physical presence, like an office, warehouse, or employees in Maine, triggers this type. If you do, you likely need to collect sales tax.
  2. Economic Nexus: This kicks in when your sales within Maine exceed a certain economic threshold. Even without a physical presence, surpassing this threshold requires collecting sales tax.

Is what you’re selling taxable in Maine?

Now that you’ve grasped the basics of Maine’s sales tax and nexus thresholds, let’s delve into whether your specific products or services are taxable.

Do you have a physical nexus in Maine?

A business has a physical nexus in Maine, which requires them to register for and collect sales tax, if they have any of the following:

  • Physical Presence: 
    • A store, office, warehouse, or any other place of business in Maine.
    • Employees, salespeople, contractors, or other representatives who regularly work within Maine. This includes employees who work remotely in Maine for your business.
Do you have an economic nexus in Maine?

What is use tax in Maine?

In Maine, use tax acts as a counterpart to the sales tax. Here’s a breakdown of what it is and how it applies:

  • Purpose: Use tax ensures fairness in the sales tax system. It applies to purchases made for use in Maine, but where the seller did not collect sales tax at the time of purchase.
  • Who Pays It:
    • Maine residents who buy items out-of-state (including online) and bring them to Maine for use are liable for use tax.
    • Businesses that withdraw taxable goods from their inventory for their own use within Maine also owe use tax.
  • Use Tax Rate: The use tax rate in Maine is generally the same as the sales tax rate, which is currently 5.5%.
Do you need a seller/reseller permit?

In Maine, the terms “seller’s permit” and “reseller certificate” are actually two sides of the same coin for sales tax purposes. Here’s how it works:

  • Retailer Certificate: This is what you get when you register for a sales tax permit in Maine. It allows you to collect sales tax from your customers.
  • Resale Certificate: This is a certificate you can provide to your suppliers to exempt yourself from paying sales tax on purchases you intend to resell.  However, to get a resale certificate, you typically need to have an active retailer certificate (meaning you’re registered to collect sales tax).

So, in essence, you don’t directly apply for a “seller’s permit.”  Instead, you register for a retailer certificate, which grants you both the ability to collect sales tax and the ability to obtain a resale certificate for tax-exempt purchases.

When are Maine's Returns Due?

Maine sales tax returns are due on the 15th day of the month following the reporting period. This applies regardless of whether you file monthly, quarterly, semiannually, or annually.

Here’s a breakdown for clarity:

  • Sold items in January: File and pay by February 15th.
