Property taxes in Winnetka can feel complicated, especially when you’re not sure which exemptions you qualify for. If you own and occupy your home, are age 65 or older, live with a disability, or are a veteran, you may be missing out on savings. The good news is Cook County offers several exemptions that reduce your taxable assessed value, which can lower your bill. This guide walks you through the key programs, how to apply, what to expect, and where to get help in Winnetka. Let’s dive in.
Core exemptions to review
Homeowner (Homestead) Exemption
If you live in your Winnetka home as your primary residence, the Homeowner Exemption is often the first place to start. It reduces the assessed value used to calculate your property taxes. This is not a dollar-for-dollar credit; it lowers the taxable value that your local districts use to set your bill.
You typically need proof of ownership and occupancy, such as a deed and a state ID with your property address. In Cook County, you apply with the Assessor. Many homeowners file once and then keep their exemption as long as ownership and occupancy do not change. Because rules can change, review the current details on the Assessor’s Homeowner Exemption overview.
Senior exemptions
If you are age 65 or older and live in your home as your primary residence, you may qualify for senior-specific savings. Cook County administers multiple senior programs, including a standard Senior Exemption and a Senior Assessment Freeze for qualifying households.
- Senior Exemption: Provides an additional reduction for eligible seniors. Review the latest rules and filing steps on the Assessor’s Senior Exemption page.
- Senior Assessment Freeze: Helps qualifying seniors with household income below a set threshold by preventing increases in assessed value. Eligibility rules and income limits can change, so confirm on the Senior Freeze Exemption page.
Plan to have proof of age, ownership, occupancy, and income documentation if you apply for a freeze.
Disabled persons and veterans programs
If you have a qualifying disability, you may be eligible for an assessment reduction. You’ll generally need proof of disability, such as documentation from a physician or a benefits agency. Check requirements on the Assessor’s Disabled Persons Exemption page.
Veterans may qualify for additional relief. Programs vary by service-connected disability status and other criteria. Typical documentation includes a DD-214 and a VA disability determination. Review current options and eligibility on the Assessor’s Disabled Veterans Homestead Exemption page and Returning Veterans Exemption page.
Home improvements and your assessment
If you remodel, finish a basement, or add living space, your assessed value may rise when the improvement is recognized by the Assessor. That could increase your future taxes. Permits help the Assessor track changes, and improvements completed during the year often affect the next assessment cycle.
Keep all permits, contractor invoices, and completion documents. Some jurisdictions offer temporary relief or phasing for certain improvements, but availability varies. Review current programs on the Assessor’s exemptions overview and ask about how and when improvements are recognized.
How to apply in Cook County
Gather your documents
For most exemptions, prepare these items before you apply:
- Proof of ownership, such as a recorded deed or recent property tax bill.
- Proof of occupancy as your primary residence, like a state ID with your property address or a voter registration card.
- Proof of age if applying for senior programs.
- Proof of disability or veteran status if applicable, such as SSA or VA documentation and a DD-214.
- Permits and contractor records if your exemption relates to improvements.
File online, by mail, or in person
The Cook County Assessor provides program details and application options on the Assessor’s exemptions page. You can usually apply online or download forms to submit by mail or in person. If you prefer hands-on guidance, the New Trier Township office can help residents understand local procedures and what to file. Find township contact information on the New Trier Township website.
Timing, renewals, and what to expect
Assessment cycle and the “as of” date
Eligibility often depends on ownership and occupancy as of a specific date tied to the tax year. That date and the assessment cycle determine when improvements and status changes will affect your bill. Because dates can change, confirm the current “as of” date and cycle details on the Assessor’s exemptions overview.
Filing windows and renewals
Apply as soon as you become eligible, such as when you purchase your home, reach age eligibility, or receive qualifying disability or veteran documentation. Some exemptions auto-renew as long as you still qualify, while others require annual re-certification. Check the renewal rules and deadlines for each program on the respective pages linked above.
When you will see savings on your bill
Approved exemptions reduce your property’s assessed value and appear on your property tax bill after the assessment roll is finalized. There can be a lag between filing and when you see the change. If you’re watching for timing or installment due dates, consult the Cook County Treasurer’s office for billing schedules and payment information.
If your exemption is denied
Appeal path and deadlines
If your application is denied, you may be able to appeal through the Cook County Board of Review. Appeal windows are strict, so mark your calendar and keep complete records. Start with the Cook County Board of Review to learn about current procedures and timelines.
Build a strong file
Keep copies of your application, all supporting documents, and any letters or emails from county offices. If you need help, township officials or a tax professional can provide guidance during the appeal process.
Quick Winnetka scenarios
New primary residence owner
You recently bought a single-family home in Winnetka and moved in as your primary residence. Gather your deed and proof of occupancy, then file for the Homeowner Exemption with the Assessor. Review your next assessment notice and tax bill to verify the exemption appears.
Winnetka senior homeowner
You are 70 and own and occupy your home. Check both the Senior Exemption and the Senior Assessment Freeze if your household income meets the county limit. Prepare proof of age, occupancy, and income documents, then file online or by mail.
Veteran with a service-connected disability
You are a veteran with a VA disability rating who owns and occupies your home. Review eligibility for the Disabled Veterans Homestead Exemption and confirm required documents like a DD-214 and VA determination letter. File with the Assessor and track when the exemption shows on your tax bill.

Next steps
If you own and occupy your Winnetka home, take an hour to review the programs that fit your situation and file before deadlines.
