This is not an eFile.com created policy, but all online tax web sites have to adhere to this IRS/state issued tax data sharing policy. You can however prepare all 44 State Income Tax Returns on eFile.com if you have already e-Filed or filed your IRS return. Instructions on how you can ONLY prepare and file State Income Tax Return(s). Only on eFile.com can you prepare, file or e-file unlimited State Tax Returns for one low price and not pay for each State return like you would do on H&R Block® vs. TurboTax®. Dare to Compare Now.
Automatic Maine Tax Extension
If you are unable to file your return by Ap
ril 15, 2021, Maine allows an automatic six month extension of time to file. This extension is only effective if the ME state return is filed within six months (by October 15, 2021).
Requests for additional time to file must be submitted in writing prior to the expiration of the 6-month period. Generally, the total extension period cannot exceed 8 months.
Please note that an extension to file your Maine tax return is NOT an extension for paying taxes owed. If you owe tax, you must pay at least 90% of that amount by the original due date for filing your return (April 15, 2021 for calendar-year filers) in order to avoid the penalty for late payment of tax. Complete and file Form 1040EXT-ME along with your ME tax payment.
The remaining 10% must be paid when the return is filed on or before October 15, 2021 in order to avoid the failure-to-pay penalty. However, interest is charged on any tax paid after the original due date of your return. Remit your extension payment with the payment voucher by the original due date for filing your Maine return to: Maine Revenue Services, PO Box 9114, Augusta, ME 04332-9114. If you make a payment prior to filing your return, you must use a Long Form (1040ME) when you file your return.
The extended Maine/IRS eFile deadline is Oct. 15, 2021 - eFileIT* now. If you plan to file or mail-in a Maine tax return on paper - the Forms and Mailing Address are below - your due date is Oct. 15, 2021. After Oct. 15, 2021, you can complete and sign 2020 Maine Tax Forms online here on eFile, before you download, print and mail them to the state tax agency. The address is on the form.
