Specifications for Form WT-7
The bar code specifications can be found at WT-7 Bar Code Specifications.
- Form WT-7 can be filed electronically . See our web site for more information.
- A check digit is required on all Form WT-7 . The check digit is required as the seventh digit of the Withholding Employer Identification Number (WEIN). The WEIN is six digits long, followed by a space, and then a check digit (for example: 123456 7). The check digit formula is available online.
- Address Changes can now be done online . See our web site for more information.
- The "LOC" box for Department Use Only on the lower-right side of the WT-7 should be prefilled with the code "999" if W-2s are submitted electronically or on magnetic media. If paper W-2s or no W-2s are submitted with the WT-7, the "LOC" box should be left blank. The code "999" can be the same font as used in lines 1 through 7 of the WT-7, but should be a 12 to 14 point font.
- Remember to use the 6-digit Wisconsin Employer Identification Number on Form WT-7 and Form W-2, not the 15-digit ITS number.
- If you must file on paper, please file with your pre-printed Form WT-7, or use the online fill-in WT-7 Form.
- Remember to verify that all the taxpayer information printed on the Form WT-7 is correct. If there has been a name or address change, check the appropriate box on the Form WT-7 to indicate the change.
- Any business change resulting in the requirement to obtain a new FEIN may also require a new WEIN be obtained. Call (608) 266-2776 for assistance if you have a new FEIN.
- For quickest service on refunds or payments due, be sure to use the appropriate mailing address shown on Form WT-7.
- If you cannot file W-2 electronically, the Department of Revenue is requesting that employers NOT use carbon copied W-2 forms including NCR. Carbon and NCR copied W-2 forms do not scan well. The preferred format for a W-2 is the IRS approved format visible on the IRS web site.
- Information on submitting W-2s electronically is also available.
- Submit one blank and one data filled WT-7 for approval.

- Amended Forms WT-7 are not reviewed until late in the year. If you file an amended Form WT-7, do not be alarmed if you do not receive a response from DOR until late in the year.
- If amending a Form W-2, please include a letter explaining the changes made to the Form W-2.
