Maine Tax Portal Account Access FAQ

What information do I need to gather before registering a new business on the MTP?

The Maine Tax Portal (MTP) is available to use for all the tax types listed at the end of this document, paid preparers, third parties, estates, anyone requesting a refund and other non-logged in options, in addition to those registering for a new business.

New business registration is only available for businesses or sole proprietors who are just starting business in Maine and need to file or pay for the very first time. Before you begin, you should gather the following information, as it is required for registration:

Federal Employer ID Number (FEIN) OR Social Security Number (SSN) for sole proprietorships only
Business legal name
Activity start date for your business
Contact information for a business representative
Contact information for your business officer(s) including title(s) and Social Security Number(s)
Physical and mailing address information
Activity start dates, filing frequencies, and fiscal months for each tax type you are registering

Fill in all required or relevant information on each step of the registration. If you need to edit any information that you entered, you can use the Previous button or click on any of the section titles listed at the top of the screen. At the end of your registration, you have the option to create a username for your new business.

I am already registered on the Maine Tax Portal to file Corporate Income Tax or one of the earlier taxes rolled out last year. What do I need to do to gain access to my Sales or Individual Income Withholding Taxes when they are available on the MTP this year?

If you have Master Access, the new Rollout 2 tax types will be viewable on the summary page after signing into the Maine Tax Portal. To gain access to the account, click on the Add access to this account hyperlink. If you don’t have Master Access, you will need to request it from someone who does.

I already have a Sales & Use or Withholding logon, do I need to make another?

If you are currently using i-File to manage your Withholding or Sales and Use Tax accounts, you will need to Create a Username on the Maine Tax Portal starting December 2022. Your i-File and/or EZpay username and passwords will not be brought into the new system.

My business already uses the Maine Tax Portal, but for taxes that I don’t handle. Do I need to create another username to use it for the taxes I work with?

Yes, another username is needed as every individual accessing the accounts should have their own username and password; passwords should not be shared. You can create another username using the instructions to Create a Username and then set up access for the tax accounts you need to work with.
It is also possible for one user to create Secondary Logons; a Secondary Logon is a username issued to another individual via email, but the access can be restricted by the issuer. This is most used when someone in a supervisory capacity needs to allow another individual within the company access to file or make payments for a specific tax or taxes.

I represent a government or municipality. Do access levels or account creation work differently for me?

No, accounts and access levels work the same for governments and municipalities as they do for Businesses.

Blueberry Tax
Business Equipment Tax Reimbursement
Cannabis Excise Tax
Corporate Income Tax
Fire Investigation and Prevention Tax (*must also be registering for Insurance Premiums)

Maine Tax Portal Account Access Overview

Web access for web logons

Security in the Maine Tax Portal is handled by specifying the web access for web logons. There are two different methods for specifying the level of access a web logon has:

Access type: Controls the actions a user can take when they are managing their profile and submitting customer-level web requests
Access level: Controls the actions a user can take when they are managing their account, a filing period, or submitting account- and period-level requests on behalf of other users

Access types

An access type is associated with a web logon in two different ways:

Access type for the web logon itself: This mainly applies to logon-level requests and access management
Access type for a specific customer: Controls the actions a user can take when they are managing their account, a filing period, or submitting account- and period-level requests on behalf of other users

MTP has three access types:

Master (Full Access): This is the primary access type for a customer; typically, there is only one Master logon for a customer. The first customer to establish credentials on the MTP for a given FEIN/SSN will be given the “Master” privileges for that taxpayer. Masters have the highest level of access for access management. These logons can also create new logons and cease existing logons
Administrator: Administrators have nearly the same access as Masters. They can create new logons, cease existing logons, and change access for other logons, though they are not able to cease Masters. By default, Administrators only have access to accounts given to them by Masters or other Administrators
User: This access type has a limited set of access. A User may be able to submit basic requests, but they cannot see or manage access for other logons

Access types

An access type is associated with a web logon in two different ways:

File Returns: File returns for the specified account(s)
Make Payments: Make payments for the specified account(s)
File and Pay: File returns and make payments for the specified account(s)
