    Third-party access

    Third-party access is when a taxpayer gives someone (for example, a paid tax preparer) access to their tax accounts. After approval, a taxpayer’s tax accounts will be added to the logon of the third party.    

    A third party initiates the process to request access rights to provide services to a taxpayer on MassTaxConnect.

    When a third party requests access to a taxpayer’s tax account(s):

    • The taxpayer has final authority on who has access and
    • What type of access is given.

    Additionally, a taxpayer can revoke a third party's access at any time.

    Estimated payments

    With third-party access, a tax professional can file and pay estimated taxes for a client. MassTaxConnect provides an instant receipt. Tax professionals can also verify payments online prior to filing a return to minimize delays in processing.
