Form WT-7 Estimates

​Over the next three to four weeks, more than 16,000 notices of estimated tax are being sent to registered employers who did not file their 2009 Employer's Annual Reconciliation of Wisconsin Income Tax Withheld from Wages (Form WT-7). You may take one of the following actions:

  • If the business became inactive prior to the tax period on the notice, return the estimated tax notice to the address on the back of the notice indicating the last date of business.
  • If the business was active but there was no withholding during the period on the notice, Form WT-7 must still be filed via My Tax Account or Telefile.
  • If the return was already filed for the period, submit a copy of the completed return, proof of payment (copies of front and back of cancelled check, or electronic confirmation number, if applicable) and the bottom portion of the estimated tax notice to the address on the back of the notice.
