Prepayment of 2018 Property & Income Tax in 2017

A special message to individual taxpayers. There has been much discussion about whether or not to prepay your 2018 property taxes due next May & November and the estimated tax payment typically due 1/15/2018 on or before 12/31/2017. These taxes are commonly referred to as SALT (state and local taxes). The correct answer is, it depends. The new tax laws recently enacted specifically address this matter and generally disallow the deduction in tax year 2017 for state and local taxes not due until 2018. There are a [very] few exceptions to this last minute addition and Indiana residents do not meet any of the exceptions. Thus, if the SALT is prepaid in 12/2017, they are not deductible on the 2017 tax return. They can be deducted under the lower thresholds on the 2018 tax return (filed in 2019).
