From May 15 to July 2, parents or guardians of children under 18 in 2017 are eligible to file for a $100 Wisconsin Child Sales Tax Refund. To qualify, a child must have been less than age 18 on Dec. 31, 2017, a dependent of the claimant for tax year 2017, a Wisconsin resident on Dec. 31, 2017 and a United States citizen. Applicants can apply at childtaxrebatewi.gov. To file a claim, applicants will need to provide your Social Security number and Wisconsin residency for tax year 2017 and your qualified child’s Social Security number and date of birth. If you choose direct deposit, you will need your bank routing number and account number. If you are a nonresident or part-year resident that moved out of Wisconsin in 2017, you must submit additional proof. Most rebates will be issued within three weeks of filing the claim.
