Tax Deductions

Wisconsin allows deductions for:

Donations: these must be itemized on your tax return to receive credit. They can include gifts to religious or charitable organizations, scientific, literary, and educational organizations, groups for preventing cruelty to children or animals, or for amateur sports competitions.

  • Cash contributions up to 50% of your adjusted gross income, and any excess can be carried forward up to 5 years.
  • Property donations: used clothing, furniture, or electronics at fair market value, NOT original cost (eg. Good Will and Salvation Army have forms you may fill out when you drop off donations with estimated values)
  • If you donate property you’ve owned for over a year that has appreciated in value and you anticipate having to pay capital gains tax on it (eg. stock, mutual fund), you can earn a deduction for its fair market value, and ultimately never pay the capital gains tax on the appreciation. Often limited to 30% of your adjusted gross income.

Mortgage Interest

Wisconsin allows the deduction of any interest paid on your home’s mortgage

You CANNOT Deduct:

  • Gifts to individuals
  • Political contributions
  • Gifts to labor unions
  • Donations to homeowner’s associations
  • Gifts used for tuition

Property Tax
