4) Please fax the above information to the I-FILE

Once all information is received and verified, we will add
you to the Ohio I-File system. Once added, you will be
able to register and use Ohio I-File and Ohio E-Payment
systems. We ask that you include a daytime telephone number
or e-mail address in the event we have any questions or if
we are unable to add you to Ohio I-File system this tax
season. If we cannot add you to the system this tax season,
you will be advised to file by paper.
We are striving to offer 24 hour turnaround response time;
however, during the Personal Income Tax filing season, there
may be additional delays due to the volume of inquiries
NOTE: Information sent to the I-File
Registration group is reviewed to determine eligibility for
using Ohio’s electronic filing methods; however it does not
guarantee that you will qualify. Based on our research if we
are unable to verify the required information to add you to
the I-File system you must complete and file a paper return
(sign it and return it to the address indicated on the form).
Please make sure you include copies of your W-2s.
