In recent weeks, there has been a dramatic increase in inquiries about paying Cook County property taxes early. According to Maine Township Assessor Susan Moylan Krey, the motivation for the increased interest in early tax payments is the change in federal tax law being considered by the US Congress. Federal law has long allowed Americans to reduce their taxable income by deducting the full amount of taxes paid to state and local governments. This includes deductions for the full amount of property taxes on homes, and for the full amount of income tax payments to states. The bill the U.S. Congress is considering, however, would limit the deduction for state and local taxes to $10,000 per year. Learn more…
