Filing requirements

Maine requires direct filing of 1099-NEC with the state for tax year 2026. Federal filing through the IRS Combined Federal/State Filing (CF/SF) Program does not, on its own, satisfy the Maine requirement for 1099-NEC; a separate state submission is required.

Maine requires direct electronic filing of Form 1099-NEC through the Maine Tax Portal (MTP) when the federal 10-return aggregate threshold is met. The IRS Combined Federal/State Filing Program is not accepted in Maine.

Registration

Registration required: Yes

Filers must register on the Maine Tax Portal (MTP) at revenue.maine.gov. Out-of-state businesses that are not otherwise required to register or pay Maine taxes must still create an MTP account to upload Forms W-2 and 1099. The transmitter's TIN in the file's T record must match the TIN associated with the MTP login. Maine does NOT accept submissions through the IRS Combined Federal/State Filing Program; do not use CF/SF.

Late-filing penalties

Maine penalty overview

$50 per failure under 36 M.R.S. § 5242 for any required information return that is not filed, or that is willfully false or fraudulent (effective 1/31/2022 forward). The Maine 1099/W-2G specifications publication restates this penalty for 1099-series filers. A separate $50 per-failure civil violation under 36 M.R.S. § 5251-A applies to a payer that fails to furnish a Form W-2 or Form 1099 to the payee.

Additional notes

Maine requires direct electronic filing of Forms 1099 with Maine Revenue Services (MRS) through the Maine Tax Portal (MTP). Filers who meet the federal 10-return aggregate electronic-filing threshold (W-2 + 1099 combined) must file electronically with MRS — and Maine specifically directs filers NOT to use the IRS Combined Federal/State Filing Program. The accepted form types are 1099-B, 1099-DIV, 1099-G, 1099-INT, 1099-K, 1099-MISC, 1099-NEC, 1099-OID, 1099-PATR, 1099-R, and W-2G; payment information from any other 1099 form (including 1099-C) is excluded from the Maine spec and will be ignored. The 2025 tax year due date is February 2, 2026 (January 31 falls on a Saturday). Form W-3ME is no longer required beginning with TY2025; quarterly Form 941ME continues. Maine plans to migrate to the IRS XML format for 1099s starting with tax year 2026.
