Where to Mail Maine State Tax Return?

Filing your Maine state tax return correctly is essential to avoid delays or processing issues. If submitting a paper return, using the correct mailing address and including all necessary documents ensures a smooth process.

Before sending your return, determine whether it includes a payment, as this affects where it should be sent.

Mailing Address With No Payment

If you are filing without a payment, use the designated address to prevent delays.

Mail your return to:

Maine Revenue Services
P.O. Box 1060
Augusta, ME 04332-1060

Maine Revenue Services processes returns separately based on payment status. Using the correct P.O. Box ensures efficient handling. Double-check the address and include all required forms to prevent delays.

Mailing Address With Payment

If your return includes a payment, send it to a different address to ensure proper processing.

Mail your return with payment to:

Maine Revenue Services
P.O. Box 1065
Augusta, ME 04332-1065

Make checks or money orders payable to “Treasurer, State of Maine” and include your Social Security number (or Employer Identification Number for businesses), tax year, and form type in the memo line. This ensures the payment is applied correctly. Do not send cash.

Enclosures and Forms

Including all necessary documents prevents processing delays. If claiming tax credits such as the Property Tax Fairness Credit or Earned Income Tax Credit, attach required schedules or worksheets. Missing documentation could delay or reduce refunds.

Attach copies of W-2s, 1099s, or other income statements to verify earnings and tax withholdings. If state income tax was withheld, including these forms ensures proper credit.

Self-employed individuals or those with business income should include Schedule C or other supporting documents detailing deductions and net earnings. Large deductions may require additional documentation.

If itemizing deductions, include relevant documentation such as Form 1098 for mortgage interest, statements for student loan interest, or receipts for medical expenses. If reporting capital gains or losses, attach Schedule D along with brokerage statements.

Confirming Your Submission

Reviewing your return before submission helps prevent errors. Verify personal information, including Social Security numbers and mailing addresses, to avoid misapplied payments or undelivered correspondence.

Check calculations for deductions and credits to ensure accuracy. Errors in reported amounts can lead to processing issues or audit triggers.

Unsigned returns are invalid and may be rejected. If filing jointly, both spouses must sign. If using a paid preparer, confirm their information, including their Preparer Tax Identification Number (PTIN), is correctly entered.

If submitting a payment, ensure the check is properly dated and signed, with the correct amount written in both numerical and word formats.
