Des Plaines Property Tax Rates and How They Work
Des Plaines Property Tax rates combine the budgets of many local taxing bodies into one final rate. These bodies include the City of Des Plaines, the local school districts, the park district, the township, the community college, and Cook County itself. Each body sets its own rate each year based on its budget needs and the total value of property in its area.
The combined local tax rate in Des Plaines sits at about 1.80% of a home’s fair market value. For a home worth $300,000, the tax bill typically comes to around $5,400 per year. Rates can shift from one year to the next based on local spending, voter-approved referendums, and changes in property values across the city.
Illinois does not put a cap on how much rates can grow from year to year. Tax bills are based on the assessed value of the property and the local tax rate for the year. The rate applies to the equalized assessed value (EAV), not the full market value. The EAV is calculated as 10% of the fair market value for most homes, then adjusted by the state equalization factor.
Key Rate Components
Your total Des Plaines Property Tax bill is the sum of rates from many local taxing bodies. The Cook County Clerk adds all the rates together into one final tax rate, which gets printed on the bill. Each body funds a different part of local services.
- City of Des Plaines: Funds city services like police, fire, public works, and roads.
- School Districts: Covers the local elementary and high school districts that serve the home address.
- Cook County: Funds countywide services like public health, courts, and the sheriff.
- Park District of Des Plaines: Runs local parks, pools, and recreation programs.
- Community College District (Oakton College): Funds local higher education needs.
- Maine Township or Elk Grove Township: Funds township services like road repair and general assistance.
Sample Tax Calculation Table
The table below shows how a sample Des Plaines Property Tax bill could break down. The numbers use a $300,000 home as an example. Actual bills vary by address, school district, and the exemptions on file.
| Item | Amount |
|---|---|
| Fair Market Value | $300,000 |
| Assessed Value (10% of market value) | $30,000 |
| Local Effective Tax Rate (of market value) | ~1.80% |
| Estimated Annual Tax Bill | ~$5,400 |
| First Installment (approximately 55% of total) | ~$2,970 |
| Second Installment (approximately 45% of total) | ~$2,430 |
Des Plaines Property Tax Assessment Process
Every three years, the Cook County Assessor reassigns a new value to each property in Des Plaines. This is called the reassessment cycle, and the year a home gets reassessed depends on which township the home sits in. Des Plaines is split between Maine Township and Elk Grove Township for assessment purposes.
During a reassessment year, the Assessor looks at recent sales of similar homes in the area. The office uses those sales to set a fair market value for the property. The new value is then multiplied by 10% to get the assessed value for most residential homes. Condos and some other property classes use different multipliers.
Once the new assessed value is set, the Assessor mails a notice to the property owner. The notice shows the old value, the new value, and the date by which an appeal can be filed. Most reassessment notices arrive in the spring or summer of the reassessment year. Homeowners who do not get a notice in those years are in a “no change” status, with the same value carrying forward.
How Assessments Affect Your Bill
Your tax bill depends on two things: the assessed value and the local tax rate. The assessed value comes from the Assessor’s office. The tax rate comes from all the local taxing bodies that serve the home. A higher assessed value leads to a higher tax bill, all else equal.
If the Assessor raises the value by 10%, the tax bill will rise by about 10% as well. If the local tax rate also rises in the same year, the total bill can climb even higher. This is why reviewing the assessment notice each year matters, even in years when no formal notice is mailed.
To check the current assessed value, search the home address at https://www.cookcountyassessoril.gov/. The search results show the year of the last reassessment and the current value. The page also shows the property class code, which affects how the value is calculated.
Des Plaines Real Estate Tax Exemptions
Property tax exemptions lower the taxable value of the home before the tax rate is applied. A smaller taxable value means a smaller tax bill. The Cook County Assessor’s office handles all exemption applications for Des Plaines properties. Most exemptions must be on file before the Assessor bills out the year.
The most common exemption is the Homeowner Exemption, which reduces the EAV by $10,000. For most homeowners, this exemption saves close to $1,000 each year on the Des Plaines Property Tax bill. The Senior Exemption adds another $8,000 reduction in EAV for homeowners age 65 and older. Together, these two exemptions can save a senior homeowner about $1,300 per year.
The Senior Freeze Exemption locks in the tax bill amount at a base year level, even when assessments rise. To qualify, the homeowner must be 65 or older, have lived in the home for at least 10 years, and meet the income limits set by the state. Recent state law changes raised the income limit, so more seniors now qualify for this valuable relief program.
Exemption Types and Savings Table
The table below lists the main property tax exemptions available to Des Plaines Property Tax payers. Each exemption has its own rules and savings level. Apply for all exemptions you qualify for to lower the bill each year. Specific savings amounts for some exemptions vary; refer to the Cook County Assessor’s Office for the most current figures.
| Exemption | Who Qualifies | EAV Reduction |
|---|---|---|
| Homeowner Exemption | Owner-occupied primary residence | $10,000 |
| Senior Exemption | Age 65 or older | $8,000 |
| Senior Freeze Exemption | Age 65+, income limit, 10-year residency | Freezes the bill amount |
| Disabled Person Exemption | Person with a qualifying disability | Amount set by Cook County Assessor’s Office |
| Disabled Veteran Exemption | Veteran with service-related disability | Amount set by Cook County Assessor’s Office |
| Home Improvement Exemption | Recent qualifying home improvements | Amount and duration set by Cook County Assessor’s Office |
How to Apply for Exemptions
The Cook County Assessor’s office makes it easy to file for most exemptions. Homeowners can apply online through the Assessor’s website or mail in a paper form. Once the office approves the exemption, it auto-renews each year as long as the homeowner still qualifies.
- Go to the Cook County Assessor website at https://www.cookcountyassessoril.gov/.
- Click on the “Exemptions” link in the main menu.
- Pick the exemption you want to apply for from the list.
- Fill out the online form with the PIN and personal details.
- Submit the form and wait for the confirmation email from the Assessor.
- Check the property record later to confirm the exemption is active.
Senior Property Tax Relief in Des Plaines
Senior homeowners in Des Plaines have several property tax relief options. These options lower the tax bill through exemptions and, in some cases, refund programs. The Illinois General Assembly passed legislation that raises the income limit for the Senior Freeze Exemption, letting more seniors lock in their tax bill at a base year amount.
To apply for the Senior Freeze, the homeowner must file the form with the Cook County Assessor’s office. The form asks for income data, residency details, and property data. Once the office approves the application, the freeze stays in place for as long as the senior lives in the home and meets the income limit. The freeze protects the homeowner from rising assessments and rising tax rates each year.
Des Plaines seniors can also apply for the regular Senior Exemption at the same time as the Senior Freeze. The two stack on top of each other, and the Homeowner Exemption can apply on top as well. With all three, a senior can save several thousand dollars per year on the Des Plaines Property Tax bill.
Common Senior Relief Programs
- Senior Exemption: Reduces EAV by $8,000 for homeowners age 65 and older.
- Senior Freeze Exemption: Locks in the tax bill at a base year level for qualifying seniors.
- Property Tax Refund for Seniors: State program that returns a portion of paid taxes to seniors with low income.
- Disabled Person Exemption: Extra relief for seniors with a qualifying disability.
- Homeowner Exemption: Reduces EAV by $10,000 for the primary residence of any owner.
Des Plaines Homestead Exemption Details
The homestead exemption in Des Plaines refers to the Homeowner Exemption, which is the most common tax break in Cook County. This exemption applies to the primary residence of a property owner. A second home or rental property does not qualify, even if the owner lives in Illinois.
To get the Homeowner Exemption, the homeowner must file the form with the Cook County Assessor’s office. The form asks for the property address, the PIN, and a statement that the home is the primary residence. Once approved, the exemption stays on the property from year to year, with no need to reapply.
New homeowners must file the Homeowner Exemption in the year they buy the home. The exemption takes effect for the next tax year after the office processes the form. Homeowners who move into a new home and forget to file miss out on the savings for the year.
How to Confirm an Exemption Is Active
Homeowners can check the active exemptions on the property at any time. The search result page on the Assessor’s website lists all current exemptions. The page also shows the date the exemption was first applied and the date it was last renewed.
- Go to the Assessor address search at https://www.cookcountyassessoril.gov/.
- Type the home address and search.
- Open the property detail page for the home.
- Look for the “Exemptions” section near the bottom of the page.
- Confirm each exemption is active and lists the correct reduction.
Des Plaines Property Tax Bill and Payment Methods
The Cook County Treasurer mails property tax bills twice each year, once in the spring and once in the fall. The first installment is due in early spring, and the second installment is due later in the year. Late payments add a penalty based on how late the payment arrives at the Treasurer’s office.
Homeowners can pay the Des Plaines Property Tax bill online, by mail, or in person. Online payments process through the Cook County Treasurer’s website, which accepts e-checks and credit cards. Mail payments should be sent well before the due date to avoid late fees that come from slow mail delivery.
The Cook County Property Tax Portal at https://www.cookcountypropertyinfo.com shows the current bill and the next due date. The portal shows the past-due balance, the current installment, and the total owed for the year. Homeowners can print a copy of the bill for their records at any time.
Payment Methods
Each payment method has its own processing time and fees. Pick the method that fits the homeowner’s needs and timeline. E-checks tend to be the cheapest online option, and mail payments have no fee at all.
- Online Payment: Fastest method, processed in 2 to 3 business days. E-checks have a small fee, and credit cards have a higher fee.
- Mail Payment: Send a check or money order with the payment stub to the Cook County Treasurer. No fees for this method.
- In-Person Payment: Visit the Treasurer’s office in Chicago to pay by cash, check, or card.
- Bank Bill Pay: Set up a recurring payment through the bank’s online bill pay system. The bank sends a check to the Treasurer.
Des Plaines Property Tax Appeals Process
If the assessed value is too high, the homeowner can file an appeal. The appeal asks the Assessor or the Board of Review to lower the value. A lower value leads to a lower Des Plaines Property Tax bill. There are two main steps in the Cook County appeal process, each with its own deadline.
The first step is filing an appeal with the Cook County Assessor’s office. This appeal must be filed within 30 days of the date printed on the reassessment notice. The Assessor reviews the appeal and may lower the value, keep it the same, or even raise it. If the office raises the value during the appeal, the homeowner can pull the appeal before it moves to the Board of Review.
The second step is filing an appeal with the Cook County Board of Review. This appeal must be filed within 30 days of the date printed on the Board’s notice. The Board of Review is a separate office from the Assessor and looks at appeals a second time. Most successful appeals use comparable sales data to show that the value on the home is higher than similar homes nearby.
Appeal Deadlines and Filing Steps
The table below shows the typical appeal timeline for Des Plaines Property Tax appeals. The exact dates change each year and vary by township, so check the Assessor’s calendar page for current deadlines before filing.
| Step | Where to File | Typical Deadline |
|---|---|---|
| Assessor Appeal | Cook County Assessor | 30 days after reassessment notice |
| Board of Review Appeal | Cook County Board of Review | 30 days after BOR notice |
| PTAB Appeal | Illinois Property Tax Appeal Board | 30 days after BOR decision |
| Circuit Court Appeal | Cook County Circuit Court | 30 days after PTAB decision |
What to Include in an Appeal
Strong appeals include evidence that the home’s value is too high. Comparable sales are the most useful evidence, showing what similar homes in the area sold for in the last year. Photos of issues with the property, like needed repairs, also help support the appeal.
- Comparable Sales: List 3 to 5 similar homes that sold for less than the assessed value.
- Property Photos: Add photos that show the condition of the home.
- Repair Estimates: Include quotes for any major repairs the home needs.
- Permit Records: Show any open permits for work that lowers the home’s value.
Des Plaines Tax District Boundaries
Each property in Des Plaines sits in several overlapping tax districts at once. These districts include the city, the school district, the park district, the township, and the county. The exact Des Plaines Property Tax rate depends on which version of each district the home sits in.
Des Plaines is split between two townships for property tax purposes. The northern part of the city sits in Maine Township, and the southern part sits in Elk Grove Township. The township affects which school district serves the home, which park district funds the local parks, and which community college district covers the area.
Homeowners can find the tax district by looking up the address on the Cook County Assessor’s website. The property detail page lists every district that covers the parcel. The list shows the rate for each district, which adds up to the total tax rate on the bill.
How to Find the Tax District
- Go to https://www.cookcountyassessoril.gov/.
- Type the home address and search.
- Open the property detail page for the home.
- Look for the “Taxing Districts” section on the page.
- Note the school district, park district, and township names.
- Compare the rates for each district to see how the total rate adds up.
Illinois Property Tax Lien and Penalties
An unpaid property tax bill becomes a lien on the home. The lien gives the county the right to collect the debt from the property owner, including through the annual tax sale. Each year, the Cook County Treasurer holds a sale of liens on properties with unpaid taxes.
Penalties for late payments grow the longer the bill goes unpaid. The first missed payment adds a small penalty, and each month of delay adds more. After about two years of unpaid taxes, the property can be sold at the annual tax sale. Once sold, the new lien holder can start the legal process to take ownership of the home.
Recent state law changes reformed the property tax sale process. The reforms give homeowners more chances to catch up on payments before losing the home. The Cook County Treasurer’s office posts details about the new rules on its website each year.
How to Avoid Tax Sale
The best way to avoid tax sale is to pay the full bill on time each year. If the full amount cannot be paid, the Treasurer’s office offers a payment plan. The plan splits the past-due balance into monthly payments with a small fee.
- Pay the full bill by the due date to avoid all penalties.
- Set up a payment plan if the full amount cannot be paid on time.
- Apply for exemptions to lower the bill before it is mailed.
- File an appeal if the assessed value looks too high.
- Contact the Treasurer’s office at the first sign of trouble to learn about relief options.
Des Plaines Property Tax Refunds
Refund claims happen when a property owner pays more tax than they owe. Common reasons for refunds include overpayment, errors in the assessed value, or successful appeals. The Cook County Treasurer’s office processes all refund claims for Des Plaines Property Tax payers.
Homeowners can search for unclaimed refunds on the Treasurer’s website. The office runs a search tool that looks at the last 20 years of payments. If a refund is owed, the tool shows the amount and the steps needed to claim the money. Many refunds go unclaimed each year because homeowners do not know to check.
To claim a refund, the homeowner fills out the form on the Treasurer’s website. The form needs the PIN, the refund amount, and proof of payment. The Treasurer’s office processes most claims within a few months of the filing date. Checks go out to the homeowner at the address on file.
How to Check for Refunds
- Go to the Cook County Treasurer’s refund search tool on its official website.
- Type the home address or PIN into the search box.
- Review the results for any unclaimed refunds or missed exemptions.
- File the claim form if the search shows a refund is owed.
- Wait for the Treasurer’s office to process the claim and send the refund check.
Des Plaines Property Tax Savings Tips
Small steps can lead to big savings on the Des Plaines Property Tax bill each year. Start by checking the active exemptions and making sure they are all on file. Many homeowners miss out on exemptions they qualify for because they never apply or move into a new home and forget to reapply.
Next, check the assessed value each year, even in non-reassessment years. Errors in property records can lead to higher bills. If a mistake is found, contact the Assessor’s office to fix it. An appeal can also be filed if the value is too high compared to similar homes in the area.
Pay the bill early to avoid late fees. The Treasurer’s office accepts payments weeks before the due date. Paying early also helps the homeowner set up a monthly budget for the next bill and avoid cash flow problems at the deadline.
Quick Savings Checklist
- Apply for the Homeowner Exemption if the homeowner owns and lives in the home.
- Apply for the Senior Exemption if the homeowner is 65 or older.
- Apply for the Senior Freeze if the income and residency rules are met.
- Review the assessed value each year for errors and signs of an overvaluation.
- File an appeal if the value is higher than similar homes nearby.
- Pay early to avoid late fees and penalties.
- Check for unclaimed refunds on the Treasurer’s website every year.
Property Tax Records Lookup and Tools
The Cook County property tax system includes several online tools for property owners. Each tool handles a different part of the tax process. Knowing which tool to use saves time when specific records are needed for a Des Plaines Property Tax review.
The Assessor’s office handles values, exemptions, and appeals. The Treasurer’s office handles bills, payments, and refunds. The Board of Review handles second-level appeals.
