Dear Friends and Clients,

The purpose of this email is to update those of you who are interested on the process of prepaying your 2017 property taxes (otherwise due in 2018) in light of the changes to the income tax code that were passed by the House and Senate this week.  Cook County has simplified its process of prepaying property taxes since our previous email.  DuPage, Kane, Lake and Will County still accept prepayment of property taxes.  However please note that prepayments for all Counties, must be received no later than December 29, 2017.

As a reminder, individuals who have been subject to the Alternative Minimum Tax (“AMT”) will likely derive less, if any, benefit than those not subject to AMT from the prepayment of local property taxes or payment of their 4th quarter estimated state income tax payments.

For those who reside in Cook County, since our previous email regarding this matter, the process to prepay property taxes online has been significantly simplified.  You no longer need to submit a request to prepay your first installment and instead can simply enter your Property Index Number (PIN) on their website at:  You will have the option to view and prepay the first installment of your 2017 property taxes payable in 2018 via e-check or credit/debit card.  The service fee for paying with an e-check is $1.00 and the processing fee for a credit card is 2.10% of the payment amount.

In addition to providing the above information regarding prepayment of property taxes, we would like to provide you with a summary of our understanding of what the new tax laws mean.  Remember that this is our most current understanding, but please do not rely solely on this.  While further implications of the new tax bill are still coming to light, rest assured that our office will do our best to determine the most advantageous approach for each client for the remainder of this year as well as the upcoming years.

Most of the proposed changes will be effective January 1, 2018.  None of the changes will affect 2017 tax returns to be filed in 2018.

Below is a summary of proposed changes we anticipate will be included in the final bill that we believe are relevant to our clients.  There is still time to plan and make necessary changes before the end of the year – please reach out to us to discuss your personal situation in greater detail.
