Treasurer's Office - General FAQ

Show All Answers

1. I mailed my payment on the due date and now I'm getting a balance due statement for an outstanding balance. Why?

By Illinois State Statues, your payment must be U.S. postmarked by the due date in order to be processed as a timely payment. If you are receiving a balance due statement, then your payment was not U.S. postmarked (metered mail is not acceptable) on time and penalties have accrued. Placing your payment in the mailbox does not guarantee the envelope will be postmarked on that day. If you are going to wait until the last day to mail your payment, the only way to guarantee the official postmark is to go to the local post office and ask to have the envelope hand stamped.

2. When will the tax bill be mailed?

The tax bills will be mailed the first part of May, with due dates in early June and September. Duplicate copies of the tax bills are available online once the bills are mailed.

3. My value went down, but my bill went up, what happened?

Assessed values are used to distribute the tax burden. If values go down, tax rates will go up. If taxing districts ask for more money, the rates will go even higher to give them the money they are requesting.

4. I have applied for and thought that I received the Senior Freeze exemption; how could my tax bill go up?

The Senior Freeze exemption does freeze the assessment, but it does not freeze the tax rates. In most cases this year, tax rates have increased. The taxing districts can continue to ask for more money and if the rate goes up then your tax bill will go up. But you have to remember that over the years; because of this exemption you have saved hundreds if not thousands of dollars each year.

5. Why was there a state multiplier?

There has always been a state multiplier, for years the factor has been one. However, the past several years the Lake County Board of Review saw record numbers of assessment appeal filings. The volume of successful appeals, coupled with valuation change requests submitted by local assessing officials, led to the need for a higher state multiplier in order to bring Lake County values on the whole to 33.33% of the market value.

6. Isn't there a cap on how much my bill can change?

Most taxing districts were allowed an increase of 3% over the request of last year, and 1.7% for the 2019 tax year. There are exceptions to this law, but it is a limit on the taxing district itself, not individual taxpayers, Individuals need to become active participants when the districts are passing their budgets. Most taxing districts requested their maximum levy.

7. Home values have been declining, so why is my bill higher?

There are several factors that could make your tax bill increase: an increase in the property equalized assessed value, an increase in tax rates, which come from the individual taxing districts, and new referendums approved by voters. Keep in mind, the assessment for your current bill is calculated as of January 2019.

8. My tax bill seems too high. Is it too late to appeal?

Basically yes, appeals should be filed within 30 days from the date of Assessment Roll Publication. The only exception would be incorrect data that the assessment was calculated on (example would be incorrect square footage). If this is the case, you should contact your local Township Assessor.

9. Will partial payments be accepted once the bills have been sent out?

Yes, partial payments can be made by mail or at the Treasurer's Office, with the understanding that the remaining balances due after the due dates could be subject to penalty.

10. Are there other items that I should be paying close attention to on the tax bill?

Yes. Please pay close attention to your total exemptions, these exemptions could lower your current tax bill. For a complete list of exemptions, go to the Assessor's website. Property Tax Relief on the assessor's site.
