1. Introduction

For software companies, SaaS providers, and technology firms conducting business in Maine,
the state's sales and use tax rules present unique challenges. Unlike some states that treat all
digital products and cloud-based services uniformly, Maine distinguishes between prewritten
(canned) software, custom software, and various technology services based on their level of
customization and method of delivery. Maine's tax treatment of software and technology-related services depends on multiple factors, including whether software is prewritten or custom, and whether services provided are classified as taxable information services or exempt professional services.

Purpose of This Guide

This guide is designed to help businesses navigate Maine's sales and use tax rules related to
software and technology services. It focuses on:

• Nexus Considerations: Understanding when businesses must register and collect Maine
  sales tax due to physical or economic presence.
• Taxability of Software & Services: Clarifying the tax treatment of prewritten vs. custom
  software, cloud computing services, and related technology offerings.
• Sourcing Rules: Determining how and where transactions are taxed based on customer
  location and method of software delivery.
• Audit Considerations: Identifying common tax audit triggers and best practices for
  compliance.
• Voluntary Disclosure Agreements (VDAs): Explaining the process for businesses to
  rectify past noncompliance while mitigating penalties and limiting back-tax liability.

Why This Matters for Technology Companies

Maine's sales tax laws impact software companies, SaaS providers, and technology firms in
multiple ways:

• Sales Tax Obligations: Businesses that sell software or related services to Maine
  customers may have a duty to collect and remit Maine sales tax, depending on how the
  product is classified and delivered.
• Cloud Computing & SaaS Complexity: Maine has limited specific guidance on cloud-
  based services, creating potential compliance challenges for businesses in this rapidly
  evolving sector. The uncertainty regarding SaaS taxability requires careful analysis of
  each transaction.
• Compliance Risks: Failure to correctly assess and collect sales tax can result in
  significant penalties, interest, and extended audit exposure. Maine's approach to taxing
  prewritten software regardless of delivery method represents a potential area of risk for
  technology companies who may mistakenly treat all electronically delivered software as
  exempt.

This guide walks through Maine's specific sales tax rules governing software, SaaS, and
technology-related services while referencing applicable statutes, administrative rules, and
Maine Revenue Services (MRS) guidance. Throughout the guide, official Maine Revenue
Services sources are linked for further reference to help technology companies stay compliant
with Maine's evolving tax landscape.
