How to Get and Use a Maine Resale Certificate: Registration, Vendors, Renewal

A Maine resale certificate lets a registered retailer buy inventory without paying the state’s 5.5% sales tax, then collect that tax from the end customer at the point of sale.¹ You don’t apply for it directly. It comes with your Maine sales tax registration, provided you expect at least $3,000 in annual gross sales. Once Maine Revenue Services (MRS) issues it, you give signed copies to your suppliers so they can sell to you tax-free.

Register for a Maine Sales Tax Account First

The resale certificate rides on top of a retailer registration with MRS, so that registration is step one.²

Register online through the Maine Tax Portal at revenue.maine.gov. Click “Register a New Business” under the Businesses panel and work through the prompts. You’ll enter your business information and your Federal Employer Identification Number; any entity other than a sole proprietor needs an EIN from the IRS. You’ll also create a login you’ll use later to file returns.²

Your application has to describe the types of tangible personal property you plan to purchase for resale and the taxable services you intend to sell. Each place of business needs its own registration, and the registration is nontransferable.³ There is no fee.

When MRS Issues the Certificate

If you indicate on your registration that you expect at least $3,000 in annual gross sales, MRS will issue a resale certificate along with your retailer certificate.¹ There is no separate form.

Below $3,000, you still register and still collect sales tax from your customers, but MRS won’t issue you a resale certificate. You pay sales tax on your inventory purchases and then claim a credit on your sales and use tax return for the tax you paid on items placed in inventory for resale.⁴ The credit works, but your cash is tied up until the return is filed.

MRS reviews active accounts annually. If you already have a retailer certificate without a resale certificate and your reported gross sales cross the $3,000 line, MRS will issue the certificate automatically.²

What You Can Buy With It

The certificate covers tangible personal property and taxable services purchased for resale.¹ Maine law excludes these transactions from the definition of “retail sale” as long as the buyer holds a valid certificate and the item will actually be resold rather than consumed by the business.⁵

Leasing qualifies. Property you buy or lease and then rent out to customers counts as a purchase for resale.⁵ What the certificate doesn’t cover: anything you use in the business rather than resell. Office supplies, equipment for your own operations, and inventory you pull off the shelf for personal use all remain taxable.

How to Present the Certificate to a Vendor

The certificate itself is a preprinted document from MRS carrying the State Tax Assessor’s authorizing signature. Your sales tax number, business name, type of activity, valid dates, and the categories of items you buy for resale are already on it. When you use it, you add the supplier’s name, sign, and date.

To make the purchase tax-exempt, you have to state in the order, written or oral, that the property or service is being purchased for resale, and you have to give the vendor a signed copy of your valid certificate. The property has to be the kind ordinarily purchased for resale by your business, matching what’s listed on the certificate.⁴ The business name on your certificate also has to match the purchase order.¹

A vendor who accepts a certificate that appears valid on its face won’t be held liable for the tax if MRS later determines the buyer wasn’t actually an active registered retailer. That protection falls away if the vendor fraudulently failed to collect the tax or encouraged the buyer to misuse the certificate.⁴ Expect your suppliers to look at your certificate carefully before honoring it.

How Long the Certificate Lasts

The length of your first certificate depends on when it’s issued. One issued before October 1 is valid for the rest of that calendar year plus the next three. One issued after October 1 is valid for the rest of that year plus the next four, so a new certificate can cover up to five years in total.¹

Renewal is automatic for retailers who reported $3,000 or more in gross sales during the previous twelve months. MRS reviews each account before the certificate expires and issues a renewed one without any action from you. Each renewed certificate runs four calendar years and expires on December 31 of the fourth year.¹

If your sales dipped below $3,000 and you weren’t renewed, you can submit a written request for a review. MRS will consider it if you reported more than $3,000 in a more recent twelve-month period, or if you can explain that temporary extraordinary circumstances caused the shortfall.¹

When your certificate renews, send fresh copies to your suppliers. An expired certificate won’t protect them in an audit.

Use Tax on Items You Keep

Every item bought with a resale certificate is supposed to be resold. If you pull something out of inventory for your own use, a sample, a demo unit, something you take home, use tax applies at 5.5%, the same rate as sales tax.⁶ The tax is due at the time you withdraw the item from inventory.⁷

You self-report this on your regular sales and use tax return, on the line for taxable purchases.⁷ This is a common audit finding. A display monitor bought “for resale” and then mounted in the store for five years will generate a use tax bill.

Penalties for Misuse

Using a resale certificate to avoid sales tax on personal purchases is tax fraud. Under Maine’s penalty statute, an underpayment due to negligence triggers a penalty of $25 or 25% of the underpayment, whichever is greater, and fraud carries steeper consequences.⁸ Interest runs from the date of the original transaction.

Misuse can also cost you the certificate. MRS can decline to renew for businesses that abuse the exemption, and a seller who knowingly participates loses the good-faith liability protection the rules otherwise provide.⁴ Auditors watch for the obvious patterns, like a landscaping company buying consumer electronics for resale.

Keep Your Registration Current

If your business name, address, ownership, or the types of property you purchase for resale change, you have to tell the State Tax Assessor in writing.³ Buying products outside the categories listed on your certificate creates problems in an audit. A clothing retailer that expands into furniture should update the registration before making those new inventory purchases tax-free.

If You’re an Out-of-State Buyer

If your business is based outside Maine and you’re buying from a Maine supplier for resale, you don’t need a Maine-issued certificate. Maine accepts the Multistate Tax Commission’s Uniform Sales and Use Tax Certificate. State-specific resale certificates from other states are not valid in Maine; only the MTC form works as a substitute. Whether your Maine certificate is honored by an out-of-state seller depends on that seller’s state.
