Types of Records to Keep

• Business Registration Documents: Keep copies of your Articles of Incorporation, LLC formation documents, and any amendments filed with the Maine Secretary of State.
• Licenses and Permits: Retain all state and local licenses or permits required for your industry, including renewals and correspondence.
• Tax Records: Maintain records of all Maine state tax filings, including sales tax, income tax, and payroll tax documents. This includes tax returns, payment receipts, and exemption certificates.
• Payroll and Employee Records: Keep detailed payroll records, employee time sheets, wage information, and employee classification documents to comply with Maine labor laws and tax reporting.
• Financial Records: Maintain bookkeeping records such as income statements, balance sheets, bank statements, invoices, and receipts for at least three to seven years to support tax filings and audits.

Retention Periods and Best Practices

As of 2026, Maine businesses should generally keep tax and financial records for a minimum of seven years. Payroll records should be retained for at least three years, while business formation and licensing documents should be kept for the life of the business.

Implementing an organized recordkeeping system, whether digital or physical, helps streamline audits, tax reporting, and compliance checks. Automation tools can assist in tracking renewal dates and maintaining consistent documentation.
