Distribution of Modernized e-File (MeF) New Web Service Definition Language (WSDLs) (Updated 12:00 p.m., Eastern on 6/17/2014)

WSDLs for Tax Year 2014/Processing Year 2015 are now available.  These WSDLs are scheduled to be installed in the MeF test environment (ATS) in November, 2014. These new WSDLs will also be required for MeF Production when it opens for Processing Year 2015.

As a reminder you should be using the la.alt URL (la.alt.www4) for ATS and la main URL (la.www4) for Production environments.

If you would like to receive the new WSDLs please send an email to MeF Mailbox. The email request must include your company name and ETIN/EFIN. The required WSDLs will be sent to you as soon as it is verified that you are a valid software developer, transmitter or State user.

Federal/State Tax Returns:

In order for standalone/unlinked returns to be accepted, the state must be participating in the State Standalone program and the Transmitter/Software Developer must NOT include an IRS Submission ID in the State Manifest. State Standalone returns may be either submitted in the same transmission (Send Submissions) as the federal return or in a different transmission.

State Testing

States wishing to transmit their own test returns need to send an email to MeF Mailbox requesting this access. We will work with you to set up a software developer account in e-Services. When that is done you will then have to create system ids for these new software developer accounts in Automated Enrollment. You will not be able to use your state accounts or system ids to transmit. However, you can use your same Strong Authentication certificates for both accounts.
