Cook County Property Tax eBilling: How to Go Paperless
The Cook County Treasurer's Office lets you receive your property tax bill by email instead of waiting for the mail. It's free, you can link up to 10 properties to one account, and eBilling users often get their bills sooner than people who wait for paper. Here's how it works, how to sign up, and what actually changes when you enroll.

The 60-Second Version
- eBilling delivers your Cook County tax bill by email — view it online, download a PDF, or print it, and pay online, by mail, or in person.
- It's free, and you can enroll up to 10 Property Index Numbers (PINs) under one account — useful for investors and families.
- Enrolling replaces your paper bill — you stop getting paper in the mail, but you can switch back anytime by unsubscribing in your account.
- eBills tend to arrive sooner than mailed bills, and the system keeps five years of your bills on file.
- Getting your bill early matters: the sooner you see your assessed value, the more time you have to decide whether to appeal.
Illinois has some of the highest property taxes in the country, and a tax bill that's delayed or lost in the mail can mean a missed due date and added interest. Under Illinois law, you owe your property taxes — plus any late interest — even if you never received the bill. Cook County's eBilling program is a simple, free way to make sure you always get yours, and to get it faster.
01 · What it isWhat is Cook County eBilling?
eBilling is the Cook County Treasurer's electronic delivery option for property tax bills. Instead of a paper bill arriving by mail, you get an email notification when your bill is ready to view online. From there you can:
- View your property tax bill online
- Download a PDF copy for your records
- Print the bill, including the payment coupon
- Pay online through the Treasurer's secure system
It works for both residential and commercial owners, and it's especially convenient if you manage more than one property.
02 · Why consider itWhy owners are switching
Four practical reasons eBilling is worth it:
- Faster access. You're emailed as soon as your bill is ready, and eBilling users often receive their bills sooner than those waiting on the mail.
- No lost or delayed mail. A bill that never arrives can still cost you in late interest. Email delivery removes that risk.
- Better records. The system keeps five years of your eBills on file, and you can save your own PDFs for accounting, refinancing, or an appeal. Digital copies are easy to find when you need them.
- Manage multiple properties. You can link up to 10 PINs to a single account — a real time-saver for landlords, investors, and anyone helping family members.
03 · How to sign upHow to enroll — step by step
Signing up is free and takes a few minutes:
- Go to the Cook County Treasurer's website (cookcountytreasurer.com) and find the sign-up link for electronic tax billing.
- Enter your details: your name, email address, phone number, and your 14-digit Property Index Number (PIN).
- Create a password and agree to the eBilling terms and conditions.
- Confirm your email within 72 hours. You'll get a confirmation email — you must reply to it within 72 hours to activate the account. Once confirmed, you'll be notified by email each installment when a new bill is ready.
04 · What changesWill you still get a paper bill?
This is the part the fine print matters on: when you enroll in eBilling, your paper bill stops. The County will email you when each eBill is ready, and you won't receive future installment bills in the mail. That's the point of going paperless — but it means you'll want your notifications working reliably.
If you'd rather go back to paper, you're not locked in: just log in to your eBilling account and unsubscribe, and mailed bills resume. And if you never enroll at all, nothing changes — paper billing stays the default. You can also view and pay your bill online at the Treasurer's site whether or not you're enrolled in eBilling.
05 · PayingYour payment options don't shrink
Going paperless doesn't limit how you pay. Your eBill includes the payment coupon, so you can still pay by mail or in person just as you would with a paper bill. You can also pay online at the Treasurer's site by credit card, debit card, or electronic check (an online payment transfers funds electronically from your bank account). The bill is the same; only the delivery changes.
06 · Mortgage escrowWhat if my mortgage company pays?
If a mortgage company manages an escrow account and pays your taxes for you, you can still enroll in eBilling. It's informational — it gives you visibility into your tax bill and assessment without affecting your mortgage servicer's ability to pay. That's useful, because the servicer pays the bill, but only you are likely to notice if your assessed value looks too high.
07 · Why it mattersGetting your bill early helps you decide on an appeal
Receiving your bill is just the first step. Your tax bill shows your assessed value — the figure that drives what you owe — and the sooner you see it, the more time you have to act. When your bill arrives, it's worth taking a few minutes to:
- Review your assessed value and compare it to similar properties nearby.
- Check for errors in your property's characteristics or exemptions.
- Plan your payment ahead of the due date.
- Decide whether to appeal — if your assessment looks too high, you have the right to challenge it.
For reference, Cook County's second-installment bills typically post in late June and arrive around July 1; the first installment is posted the prior November. Appeal windows, though, are set separately by township and run on the Assessor's calendar — so the earlier you review your value, the better positioned you are when your township opens.
Think Your Assessment Is Too High?
Getting your bill faster is step one. If your assessed value looks too high, see what an appeal could save — enter your address or PIN. No upfront cost. 25% of first-year savings, only if your assessment is reduced.

Does eBilling cost anything?
No. Enrolling in Cook County eBilling is free. You sign up on the Treasurer's website with your name, email, phone number, and 14-digit PIN.
If I enroll, will I still get a paper bill?
No. Once you enroll, the County emails you when each eBill is ready and you stop receiving paper installment bills in the mail. If you want paper back, log in to your account and unsubscribe, and mailed bills resume.
Can I manage more than one property?
Yes. You can enroll up to 10 Property Index Numbers (PINs) under a single eBilling account — convenient for investors, landlords, and families managing multiple properties.
What if my mortgage company pays my taxes through escrow?
You can still enroll. eBilling gives you informational access to your tax bill and assessment without affecting your mortgage company's ability to pay from escrow.
How long are my eBills kept, and how do I activate my account?
The system retains five years of eBills; save a PDF if you want a longer record. After signing up, you must reply to the confirmation email within 72 hours to activate your account.
Does signing up for eBilling start a property tax appeal?
No — eBilling only changes how you receive your bill. But seeing your assessed value sooner gives you more time to decide whether to appeal. If your assessment looks too high, you can file a separate appeal during your township's window.
