Under 35 ILCS 200/, all property in Des Plaines must be assessed at 33 1/3 percent of fair market value.

The city, county, park district, library, and other local governments each add their share. Because these districts overlap differently across the city, tax rates can vary from one block to the next.

Under 35 ILCS 200/, the lien date is January 1 each year. Whoever owns the property on that date is on the hook for the taxes. Cook County tax bills typically arrive later than in other Illinois counties. The first installment is usually due in March. The second installment comes in the summer or fall.

Des Plaines Property Tax Exemptions

Des Plaines property owners can apply for exemptions that reduce their tax bill. Forms go through the Maine Township Assessor or the Cook County Assessor's Office. The General Homestead Exemption cuts $10,000 from your assessed value if you own and live in the property. Cook County uses a higher exemption amount than the rest of Illinois. This is the most common exemption in Des Plaines property records.

Seniors age 65 and up qualify for the Senior Citizens Homestead Exemption, which takes another $8,000 off the assessed value. The Senior Citizens Assessment Freeze locks your assessed value if you meet income limits, keeping your taxes from rising even as the market moves. The Long-time Occupant Homestead Exemption helps those who have owned and lived in the same home for at least 10 years in areas with rising values.

• General Homestead Exemption: $10,000 reduction (Cook County)
• Senior Citizens Homestead Exemption: $8,000 (age 65+)
• Senior Citizens Assessment Freeze: locks value in place
• Disabled Persons Homestead Exemption: $2,000 reduction
• Disabled Veterans Homestead Exemption: varies by VA rating
• Long-time Occupant Homestead Exemption: for 10+ year residents

You must apply for exemptions. They are not automatic. New homeowners should file for the General Homestead Exemption as soon as they close on the property.

Appeal Des Plaines Property Assessments

If your Des Plaines property records show an assessed value you believe is too high, you can file an appeal. The first step is to appeal to the Cook County Assessor during the open window for Maine Township. Each township has its own appeal period, and the Assessor's website publishes the schedule. You need comparable sales data showing similar homes sold for less than what your assessment implies.

If the Assessor does not adjust your value, the next step is the Cook County Board of Review. This is a separate office that handles appeals after the Assessor has ruled. You submit evidence, and the Board looks at recent sales of comparable homes to determine if your assessed value is fair. The process costs nothing. You do not need an attorney, though some owners hire one for complicated properties. Beyond the Board of Review, the Illinois Property Tax Appeal Board is the state-level option.
