Summary
Summary
Maine taxes prewritten software when sold, rented, leased, or licensed in a taxable form. Rule 326 outlines the specific criteria for software to be subject to Maine sales tax, including tangible medium storage and electronic transfer. Remotely accessed software from out-of-state servers is generally not taxable when no software is downloadable.
Background
Maine’s framework is relatively favourable for pure SaaS and remotely accessed cloud software, but taxable for downloaded or otherwise electronically transferred prewritten software. The most important current source is Maine Revenue Services(MRS) Rule 326, effective for lease and rental transactions from January 1, 2025, which gives detailed software treatment.
MRS Rule 326 states that custom software is excluded from taxable tangible personal property, while prewritten software sold, leased, rented, or licensed for consideration is generally taxable when transferred on tangible media, by “load and leave,” or electronically where it is downloadable in Maine or for use in Maine.
It also states that remotely accessed software from an out-of-state server is not taxable where no software is downloadable onto the customer’s device.
Maine Sales and Use Tax
Maine imposes sales tax on the value of tangible personal property, products transferred electronically, and taxable services sold at retail in Maine. The general sales tax and use tax rate is 5.5%.
Maine’s use tax complements the sales tax. If taxable tangible personal property, a taxable electronically transferred product, or a taxable service is used in Maine and sales tax was not collected, the purchaser may owe Maine use tax.
Maine Revenue Services states that if the seller does not collect sales tax, the purchaser owes Maine use tax payable directly to MRS based on the sale price.
For remote digital providers, the analysis should therefore follow three questions:
- Is the item or service taxable in Maine?
- Does the seller have a Maine collection obligation?
- If the seller does not collect, does the purchaser have a Maine use tax obligation?
Canned or Prewritten Software
Maine taxes prewritten software when it is sold, rented, leased, or licensed in a taxable form. Rule 326 states that prewritten software programs for sale, rental, lease, or license are generally subject to Maine sales tax. It specifically identifies software stored on a tangible medium, such as a disk or USB drive, as taxable.
It also treats software transferred using a “load and leave” method as taxable because the software is delivered on a tangible medium.
Electronically transferred prewritten software is also taxable when it is downloadable in Maine or for use in Maine and sold, rented, leased, or licensed for consideration. Rule 326 expressly includes mobile apps downloadable to a smartphone, tablet, or other mobile device.
How does this statutory provision translate in a real-life sales transaction:
A foreign software company sells a downloadable inventory management application to a Maine business. The customer pays a licence fee and downloads the software for use in Maine. This is generally taxable Maine prewritten software. If the seller has Maine nexus, it should collect Maine sales tax. If the seller does not collect, the purchaser may owe Maine use tax.
Licence Fees, Upgrades, and Maintenance
Maine treats a licence fee to use prewritten software for a defined period as a lease or rental of the software. Rule 326 states this directly. It also provides that enhancements to prewritten software, including upgrades, in-app purchases, and in-game purchases, are subject to Maine sales and use tax if the underlying prewritten software is taxable.
Software maintenance contracts are also important. Rule 326 states that a retailer makes a retail sale of tangible personal property when it enters into a computer software maintenance contract to provide future updates or upgrades, and those contracts are subject to Maine sales and use tax when entered into.
If maintenance is included in a single non-itemized price with taxable prewritten software, the entire transaction is taxable.
How does this statutory provision translate in a real-life sales transaction:
A SaaS provider sells a downloadable desktop client for USD 500 and separately sells annual update rights for USD 100. If the desktop client is taxable prewritten software, the update contract is also taxable. If the update and software charges are bundled into one price, Maine may tax the full bundled amount.
Customized Software
Maine generally excludes custom computer software from taxable tangible personal property. Rule 326 defines a custom computer software program as software written or prepared exclusively for a particular customer. It further states that custom software programming is not subject to Maine sales or use tax because custom computer software programs are excluded from the definition of tangible personal property.
However, Maine does not allow every modified software product to become fully exempt. Rule 326 states that an existing prewritten software program modified to meet a particular customer’s needs is custom software only to the extent of the modification and only where the modification charge is separately stated.
How does this statutory provision translate in a real-life sales transaction:
A Maine customer buys a standard downloadable ERP system and pays an EU developer to build a customer-specific module. The standard ERP software remains taxable. The separately stated custom development charge may be nontaxable if it is genuinely specific to that customer and properly itemized.
SaaS and Cloud-Based Services
Maine’s treatment of pure SaaS is relatively favourable. Rule 326 states that prewritten software sold, rented, leased, or licensed for consideration, where the software is remotely accessed over the internet from an out of state server, private or public networks, or wireless media, and where no software is downloadable onto the licensee’s computer or device, is not considered a retail sale of a product transferred electronically and is not subject to Maine sales and use tax.
MRS repeated this point in its public responses to comments on Rule 326, confirming that cloud-based software resting on an out-of-state server is not taxable where no software is downloadable to the customer’s device.
How does this statutory provision translate into a real-life sales transaction:
A software provider based in Italy sells access to a browser-based CRM platform to a Maine company. The customer logs in through a web browser, and no software is downloaded to the customer’s device. Under current Maine guidance, this ordinary SaaS subscription is generally not subject to Maine sales or use tax.
Remote Access with Downloadable Parts
The key SaaS risk is whether the customer receives any downloadable software component. If a customer can download a desktop client, app, connector, agent, or other software for use in Maine, the transaction may no longer be pure remote access.
Rule 326 taxes electronically transferred prewritten software that is downloadable in Maine or for use in Maine.
This means contracts and product architecture matter. A browser-only product is safer. A SaaS model that requires a paid local client or downloadable application requires separate tax analysis.
How does this statutory provision translate into a real-life sales transaction:
A cloud backup service charges Maine customers for online storage and also requires a paid downloadable desktop synchronization application. If the downloadable application is prewritten software and is not merely incidental or free, Maine may tax the software component, and possibly related upgrades or maintenance.
Digital Products
Maine taxes “products transferred electronically” where the digital product transferred electronically would be taxable in nondigital physical form. The Maine statute defines a product transferred electronically as a digital product transferred electronically, the sale of which in nondigital physical form would be taxable as tangible personal property.
From January 1, 2026, Maine also taxes digital audiovisual and digital audio services. MRS General Information Bulletin 115 states that digital audiovisual and digital audio services are subject to sales tax from that date. It defines those services as electronic transfers of digital audiovisual works and digital audio works to an end user with a right of less than permanent use, including subscriptions or access conditioned on continued payment.
This is a material update because it brings subscription-based digital audio and video consumption into the sales tax framework, even where the customer does not obtain permanent ownership.
How does this statutory provision translate into a real-life sales transaction:
A foreign streaming provider sells monthly access to music or video content to Maine customers. From January 1, 2026, that subscription can fall within Maine’s taxable digital audiovisual and digital audio services rules.
Economic Nexus
Maine requires remote sellers to register and collect sales tax if they meet the economic nexus threshold. MRS states that a seller without physical presence should register if, during the current or previous calendar year, it made sales of tangible personal property, products transferred electronically, or taxable services for delivery into Maine in at least 200 separate transactions, or had gross revenues from those Maine sales exceeding USD 100,000.
Remote sellers meeting those thresholds but failing to register may be subject to assessment for uncollected or unremitted Maine sales and use taxes.
For foreign providers, there is no special exclusion. A non US provider selling taxable digital products, downloadable software, or taxable digital audiovisual services into Maine should apply the same threshold analysis.
Maine Sales Tax Collection and Remittance
Local sellers
A Maine-based seller making regular sales of tangible personal property or taxable services should register for a sales tax account. MRS states that taxable services include several specified categories, including telecommunications, cable and satellite television or radio services, fabrication services, and, from 2026, digital audiovisual and digital audio services.
Remote sellers
A remote seller should register and collect if its Maine gross revenue from tangible personal property, electronically transferred products, or taxable services exceeds USD 100,000 in the previous or current calendar year. MRS also identifies the 200 transaction threshold in its remote seller guidance.
Marketplace facilitators
A marketplace facilitator should collect on facilitated taxable marketplace sales delivered into Maine. This applies even where the marketplace seller itself would not otherwise be required to register.
Purchasers
If the seller does not collect tax on a taxable purchase, the purchaser owes use tax directly to MRS. There is no general purchaser-side monetary threshold that eliminates the use tax obligation. The USD 100,000 and 200 transaction thresholds relate to the seller’s duty to register and collect, not to whether a purchaser owes use tax.
B2C and B2B Transactions
Maine sales and use tax applies to taxable retail sales and taxable use. It is not limited to B2C transactions.
A Maine business can owe tax on taxable prewritten software, downloadable software, taxable electronically transferred products, and taxable digital audiovisual or audio services if bought for business use and no exemption applies.
A business customer’s sales tax registration number does not, by itself, make the purchase exempt.
For B2B transactions, the main difference is documentation. The seller may accept a valid resale certificate or exemption certificate where the buyer is purchasing for resale or qualifies for a specific exemption.
Maine Rule 302 explains the circumstances under which a retailer can support exempt sales, and a nongovernmental entity generally should hold an exemption certificate issued by MRS to make tax-free purchases.

Final Remarks
Maine’s current framework is favourable for ordinary SaaS and pure cloud access, but not for downloadable software. Prewritten software delivered on tangible media, by load and leave, or electronically where downloadable in Maine or for Maine use is generally taxable.
Custom software is generally not taxable, and separately stated customer-specific modifications may also be excluded. Pure SaaS accessed remotely from an out-of-state server is generally not taxable if no software is downloadable to the customer’s device.
Remote and foreign providers should register once they exceed USD 100,000 of Maine gross revenue or 200 Maine transactions in the current or previous calendar year for sales of tangible personal property, electronically transferred products, or taxable services delivered into Maine.
Marketplace facilitators collect on facilitated taxable marketplace sales. B2B sales are not automatically exempt merely because the buyer is registered for sales tax. If the transaction is taxable and no resale or exemption certificate applies, the remote provider should collect Maine tax.
Frequently Asked Questions
Generally, pure SaaS is not subject to Maine sales tax where the customer only remotely accesses software hosted on an out-of-state server, and no software is downloadable to the customer’s device.
This makes Maine relatively favourable for browser-based SaaS and cloud software providers.
Generally, no.
Maine Rule 326 provides that remotely accessed software is not treated as a taxable electronically transferred product where the software is accessed from an out-of-state server and cannot be downloaded onto the customer’s computer or device.
The distinction between remote access and downloadable software is therefore central to Maine taxability.
Maine’s general sales and use tax rate is 5.5%.
The same general rate applies to taxable purchases where use tax becomes due because the seller did not collect the required Maine sales tax.
Generally, no.
Custom software written or prepared exclusively for a particular customer is excluded from taxable tangible personal property under Maine’s software rules.
However, a standard prewritten software product does not automatically become exempt merely because it is modified for one customer.
A separately stated charge for genuine customer-specific modifications can generally be treated differently from the underlying prewritten software.
The standard software can remain taxable while the separately identified custom development portion may qualify as nontaxable.
Clear invoicing and contractual separation are therefore important.
Licence fees for taxable prewritten software can be subject to Maine sales tax.
Maine Rule 326 treats a licence to use prewritten software for a defined period as a lease or rental of the software.
The delivery method remains important because downloadable or otherwise electronically transferred software can be taxable, while pure remote access may be treated differently.
