Wisconsin Electronic Filing Program Information
for Tax Professionals
Tax professionals that produce returns for electronic transmission are called Electronic Return Originators (EROs). The Internal Revenue Service (IRS) must approve all EROs.
How to become an authorized Electronic Return Originator (ERO) with the State of Wisconsin
- Tax professionals must complete an online application with the IRS to participate in the Authorized e-file Provider Program. For more information about the IRS application process, visit their website or call toll free at 1-866-255-0654.
- Once the IRS has accepted you as an ERO, you will automatically be accepted as an authorized ERO in Wisconsin. As a tax professional, you should be in good standing with the Wisconsin Department of Revenue (DOR) for both business and personal tax liabilities.
- DOR will no longer send out acceptance letters. Publication 115, Handbook for Federal/State Electronic Filing, is available to download from our website.
- The IRS has a database on their website for taxpayers to locate an ERO in their area. Check out their website at irs.gov/efile/page/0,,id=10162,00.html to see if you are on the data base and your information is correct. If you need to add or change any information, follow the instructions the IRS provides on their web page.
