Lake County Tax Cycle: What Lake Zurich Buyers Should Know

If you are buying in Lake Zurich, property taxes can feel like a moving target. You want a clear picture of what you will owe at closing, what your lender will collect, and how future bills might change. You deserve straightforward guidance, not surprises. In this guide, you will learn how Lake County’s tax cycle works, how prorations are calculated at closing, what to expect with escrow, and the simple steps to stay ahead. Let’s dive in.

How Lake County taxes work

Lake County uses a two-installment system. Taxes for a given tax year are billed and paid in two separate payments. Exact installment due dates can change, so you should verify current dates with the Lake County Treasurer before you set expectations for closing funds.

Your tax bill is built in stages. The assessor determines the assessed value, applying any eligible exemptions. Local taxing districts then set their levies. The county calculates the tax rates and prepares bills for the payable year. Bills are then issued and due in two installments.

Because levies and equalization can change year to year, the amount you face after closing may differ from the last posted bill. Title companies and lenders usually rely on the most recent available bill, or the prior year, when they estimate prorations and escrow.

What appears on a Lake Zurich bill

Lake Zurich buyers typically see several taxing bodies on the bill. These can include Lake County, the Village of Lake Zurich, Lake Zurich school district(s), the township, the park district, the library district, and fire district(s). Special assessments, such as sidewalks or sewer improvements, may show as separate line items.

If you see a special assessment, confirm whether it is a one-time charge or part of a multi-year installment plan. That can affect your closing numbers and future escrow.

How taxes are prorated at closing

Proration splits the property tax for the tax year between seller and buyer based on how long each owns the home during that year. The seller typically covers the period up to the day of closing, and you cover the period after.

Most closings use the latest tax bill available. If a current bill is not out yet, the title company usually estimates using the prior year’s total. When the actual bill arrives, the contract often allows for a reconciliation so the party who underpaid can settle the difference.

Common closing scenarios

• Seller paid the full year before closing. The seller receives a credit for the portion that covers your ownership period after closing.
• Seller paid only the first installment. You will see a credit or charge based on dates and which period that installment covers. If the second installment is due soon after closing, your lender may collect at closing to ensure the payment is made on time.
• No current bill available. The title company prorates using the prior year’s bill and adds contract language for a future adjustment when the new bill posts.
• Delinquent taxes or unpaid special assessments. These typically must be cleared by the seller at or before closing, or handled in writing with specific payoffs.

Escrows and what your lender collects

Many lenders require an escrow account to pay your taxes and insurance. At closing, the lender may collect an initial deposit so there are enough funds on hand when the next installment comes due. Federal rules allow lenders to maintain a small cushion in escrow, and practices vary by lender.

If a tax installment is due right after closing, expect your lender to collect additional funds at closing. This protects you from a late payment and helps keep your monthly escrow on track.

Contract must-knows in Lake Zurich

Well-written contracts reduce surprises. Key items to confirm include:

• The proration date, which is often the date of closing.
• Which tax year or bill will be used if the current year is not available, often the prior year.
• Who pays any delinquent taxes and penalties.
• How special assessments billed before closing are handled, and what happens with future installments.

Pre-closing checklist

• Get the most recent tax bill from the seller, plus receipts for any installments paid.
• Ask the title company for a tax certificate to confirm status and any delinquencies if bills are not available.
• Check for any special assessments or recorded payment plans tied to the property.
• Ask your lender for an itemized estimate of required escrow deposits so you know your cash to close.
• Verify what exemptions are currently applied to the property.

At closing: quick review

• Review the Closing Disclosure line items for tax prorations and escrow collections.
• Confirm the title company cleared any delinquent items or set up an escrow as needed.
• Leave with written instructions on how and when to apply for exemptions after closing.

After closing: next steps

• Update the mailing address for future tax bills right away.
• Apply for the Illinois Homeowner Exemption if you qualify. Exemptions usually do not transfer automatically to new owners.
• Save your closing statement in case you need to reference tax credits or adjustments later.

Avoid common surprises

• New or higher assessments. Ask the municipality and seller about pending improvements or special assessments during due diligence.
• Escrow shortages. If tax bills rise, your lender’s escrow analysis may increase your monthly payment. Talk with your lender about this possibility before closing.
• Reconciliation gaps. If proration used last year’s bill and the new bill is higher, be ready for a contract-based adjustment once the bill arrives.

Simple proration example

Example: If last year’s total taxes were 4,800 dollars and you close exactly halfway through the tax year by days owned, a basic day-count split would be 2,400 dollars to the seller and 2,400 dollars to you. Real closings follow your contract, installment timing, and lender escrow needs, so your numbers may differ. Ask your title company and lender for your exact figures.

FAQs

Who pays property taxes at a Lake Zurich closing?

• Taxes are prorated so each party pays for the portion of the year they own the property. What is billed or paid before closing, plus your contract terms, sets the final numbers.

What if the current Lake County tax bill is not available?

• Closings usually use the prior year’s bill as an estimate and include contract language for a later adjustment when the current bill is issued.

Will my mortgage lender handle tax payments?

• If your loan includes an escrow account, the lender will collect monthly funds and pay tax installments when due. At closing, they may collect an initial deposit to cover the next payment.

Can I transfer the seller’s homeowner exemption to my name?

• Exemptions generally do not transfer automatically. New owners typically must apply with the county to claim a homeowner or homestead exemption.

What happens if taxes are delinquent before closing?

• Delinquencies should appear on the title company’s tax certificate. They are usually paid off by the seller at closing or addressed in writing, since unresolved taxes can prevent clear title.

Are special assessments part of the tax proration?

• Many special assessments appear on the tax bill and are prorated or handled separately depending on billing timing and what your contract specifies.
