The Maine service provider tax is a 6% tax on the sale of seven specific service categories in the state, administered by Maine Revenue Services alongside the 5.5% general sales tax. The legal obligation to pay sits with the service provider, not the customer, even when the provider passes the cost through on an invoice.1Maine Revenue Services. Sales, Use & Service Provider Tax
Which Services Are Taxed
The tax applies to a short, closed list. If what you sell isn’t on it, the service provider tax doesn’t apply, though the general sales tax might. The seven categories are:
- Telecommunications services, both mobile and landline.
- Installation, maintenance, or repair of telecommunications equipment.
- Extended cable and satellite television service. Basic service may not trigger the tax; premium and expanded packages do.
- Fabrication services, meaning producing tangible goods from materials someone else provides.
- Ancillary services sold with a primary taxable service, such as detailed billing, directory assistance, voicemail, and conference bridging.
- Rental of video media and video equipment.
- Rental of furniture, audio media, and equipment under a rental-purchase agreement.
Ancillary services catch providers off guard more than any other category. A telecommunications company that collects correctly on core service but overlooks voicemail or detailed billing charges is building up an unpaid liability that Maine Revenue Services treats as independently taxable at 6%.2Maine Revenue Services.

Who Owes the Tax
Maine holds the provider liable for the full amount owed on taxable services sold, whether or not the provider collects it from the customer. You can pass the cost through on a bill, but if you do, it must appear as a separate line item labeled as service provider tax. You can also absorb it. Either way, the state expects payment based on the full value of the taxable service.
Bundling is where this gets dangerous. If a provider sells a taxable service together with a non-taxable one and fails to separate the charges on the invoice, Maine Revenue Services can apply the 6% rate to the entire transaction.3Maine Revenue Services. Sales and Use Tax Rates & Due Dates A telecom bundle that lumps internet (not taxable) with voicemail and detailed billing (taxable) needs the taxable portions broken out. Across thousands of customer bills, getting this wrong creates liability that stacks up fast.
Exempt Customers
Qualifying nonprofits and government entities are exempt. The list includes 501(c)(3) organizations, hospitals, schools, churches, fire departments, libraries, government agencies, and a range of healthcare-related organizations that meet criteria under Title 36.4Maine Revenue Services. Maine Sales Tax Exempt Organizations Collect a valid exemption certificate before treating any sale as exempt and keep it on file. Without the certificate, the provider stays liable for the tax even if the customer legitimately qualified.
Registering, Filing, and Paying
Any business selling taxable services in Maine must register with Maine Revenue Services before collecting or remitting the tax. Registration runs through the Maine Tax Portal and requires a Federal Employer Identification Number, or a Social Security Number for sole proprietors without one.5Maine Revenue Services. Sales, Use, and Service Provider Tax FAQ Your business name must match IRS or Secretary of State records.
Returns are due by the 15th of the month following the reporting period. If the 15th falls on a weekend or holiday, the deadline moves to the next business day.6Maine Revenue Services. List of Forms and Due Dates Maine Revenue Services assigns a filing frequency, monthly, quarterly, or semi-annual, based on your liability volume at registration.3Maine Revenue Services. Sales and Use Tax Rates & Due Dates Most high-volume providers file monthly.
Filing and payment both happen through the Maine Tax Portal, typically by electronic funds transfer from a verified business bank account. File a return for every reporting period even if you had zero taxable sales. Skipping a zero period still counts as a failure to file.
Penalties for Late Filing or Non-Payment
Maine’s penalty structure under Title 36 has two tracks, and they stack.
Failure to File
If your tax liability for a period exceeds $25 and you don’t file on time, the penalty is $25 or 10% of the tax due, whichever is greater, so long as you file within 60 days of receiving a formal demand from the State Tax Assessor. Miss that 60-day window and the penalty rises to $25 or 25% of the tax due, whichever is greater.7Maine State Legislature. Maine Code Title 36 187-B – Penalties
Failure to Pay
Late payment carries a separate penalty of 1% of the unpaid tax for each month or partial month the balance stays outstanding, capped at 25% of the unpaid amount. Ignore a final assessment with no further appeals available and fail to pay within 10 days of a demand notice, and the penalty is a flat 25% of the tax due.7Maine State Legislature. Maine Code Title 36 187-B – Penalties
Negligence and Fraud
Understating tax through negligence triggers a penalty of $25 or 25% of the underpayment, whichever is greater. If the understatement is fraudulent, the penalty triples to $75 or 75% of the underpayment.7Maine State Legislature. Maine Code Title 36 187-B – Penalties A fraudulent return filed late draws both tracks at once.
Personal Liability for Officers and Responsible Persons
Corporate structure doesn’t shield you from this one. Under Maine law, any officer, director, member, agent, or employee who controls the business’s finances or is responsible for paying its taxes can be held personally liable for unpaid service provider tax, plus interest and penalties.8Maine Legislature. Maine Code Title 36 177 – Trust Fund Status of Certain Collections Maine treats collected service provider tax as trust fund money. It belongs to the state from the moment you collect it. Diverting those funds to cover payroll or other expenses doesn’t change the obligation, and the state can pursue the individual who made that call.
If you’re an officer, LLC member, or manager with authority over tax payments, remittances need to happen on time, every period. Personal liability survives the business closing, and collection can reach your personal assets.
Records to Keep
Maine requires every taxpayer to maintain records the State Tax Assessor considers necessary for administering the tax. That means invoices, receipts, exemption certificates, and anything that documents the value of taxable services sold and separates taxable from non-taxable revenue.9Maine State Legislature. Maine Code Title 36 135 – Record-Keeping Requirements
Records must be retained for at least six years and kept accessible for inspection.9Maine State Legislature. Maine Code Title 36 135 – Record-Keeping Requirements Six years is the floor. For periods where no return was ever filed, or where a return was fraudulent, there is no time limit on how far back the state can look. In those situations, keep records indefinitely.
The most common audit problem is poor separation between taxable and non-taxable revenue. If your books don’t clearly show which charges were for taxable services, the state can treat the whole amount as taxable and assess accordingly. Clean books kept from the start cost less than reconstructing them during an audit.
2025 Statutory Change
In 2025 the Maine Legislature passed PL 2025, c. 388, which repealed the individual sections of Chapter 358, the original statutory home of the service provider tax. The tax itself was not eliminated. Maine Revenue Services still administers it at the 6% rate. The repeal consolidated the framework within the broader sales and use tax provisions of Title 36. If you’re working from older guidance that cites sections like § 2552 or § 2553, those sections are no longer in force as standalone statutes, though registration, filing schedule, and rate are unchanged.
