How Tazewell County Calculates Taxes
Here’s the straightforward math behind your property tax bill: the Tazewell County assessor determines your property’s assessed value, then multiplies it by the local tax rate (called the mill levy). The result is your annual property tax obligation. Sounds simple, right? The complexity comes in how that assessed value gets determined in the first place.
In Illinois, property assessment happens every three years through a systematic review process. Your home’s assessed value is typically 33.3% of its market value—this is called the assessment level. So if your home is worth $300,000 in the current market, the county might assess it at $100,000 for tax purposes. That $100,000 figure then gets multiplied by the applicable tax rates for schools, county services, fire protection, and other local entities.
The mill levy varies depending on your specific location within Tazewell County. A property in Pekin might have a different total levy than one in Tazewell or Washington, because each municipality, school district, and special district sets its own rate. This is why two homes of similar value can have significantly different tax bills depending on their exact address.
Assessment Process Explained
The Tazewell County Assessor’s office conducts assessments using a mass appraisal system that evaluates comparable properties in your neighborhood. They look at recent sales, property characteristics (square footage, age, condition, lot size), and market trends. This isn’t a personal visit to your home every year—it’s a statistical analysis based on data they’ve collected.
Assessment years in Illinois follow a three-year cycle. Your property gets reassessed once every three years, with new assessed values taking effect on January 1st of the following year. For example, if your property is assessed in 2023, the new assessed value appears on your 2024 tax bill. Between assessment years, your value typically stays the same unless you appeal or make significant improvements.
The assessor’s office must send you a notice before your assessed value changes. This notice gives you time to review the assessment and file an appeal if you believe it’s inaccurate. Many property owners miss this window because they don’t recognize the notice or don’t understand what it means. That’s a costly mistake—appeals filed after the deadline are much harder to win.
Homeowner Exemptions Available
Illinois offers several exemptions that can significantly reduce your Tazewell County property tax bill. The most common is the homestead exemption, which reduces the assessed value of your primary residence. In Illinois, this exemption reduces your home’s assessed value by up to $6,000 (though the exact amount varies by county and year).
To qualify for the homestead exemption, you must occupy the property as your primary residence on January 1st of the assessment year. You’ll need to file an application with the assessor’s office—it doesn’t happen automatically. Many homeowners don’t realize they need to apply, and they miss out on hundreds of dollars in annual savings.
Beyond the standard homestead exemption, Illinois offers additional relief programs:
- Senior Assessment Freeze: If you’re 65 or older and meet income limits, your assessed value can be frozen at the level from your first year of qualification.
- Disabled Person Exemption: Property owners with disabilities may qualify for an exemption that reduces assessed value.
- Agricultural Exemptions: If you own farmland in Tazewell County, special agricultural assessment rates apply.
- Veteran Exemptions: Disabled veterans may qualify for additional property tax relief.
Each exemption has specific eligibility requirements and deadlines. Filing these applications early in the calendar year gives you the best chance of approval for that tax year.
Challenging Your Assessment
If you believe the Tazewell County assessor overvalued your property, you have the right to file an appeal. This is one of the most underutilized tools available to property owners. Many people assume their assessment is correct simply because it came from the government, but assessments are frequently inaccurate.
The first step is gathering evidence. Collect recent sales of comparable homes in your neighborhood, get a professional appraisal if the property is significantly overvalued, and document any property defects or issues that would reduce value (foundation problems, outdated systems, poor condition). The key is showing that your assessed value doesn’t match current market conditions or comparable properties.
In Tazewell County, you’ll file your appeal with the Board of Review, typically between May 1st and June 30th following the assessment notice. You can appeal by mail, in person, or through a formal hearing. If you’re appealing a significant overvaluation, hiring a property tax attorney or assessor can be worthwhile—their fees often pay for themselves through reduced assessments.
If you’re unsuccessful at the Board of Review level, you can appeal to the Illinois Property Tax Appeal Board (PTAB). This is a state-level agency that hears property tax disputes. While the process takes longer, PTAB decisions are often more favorable to property owners because they focus purely on comparable sales data and market analysis.
Senior and Disability Relief Programs
Tazewell County residents age 65 and older have access to the Senior Assessment Freeze Program, one of the most valuable property tax benefits in Illinois. Once you qualify, your assessed value is frozen at the level from your first year of participation. Even if your home’s market value increases significantly, your assessment stays the same, protecting you from rising tax bills.
To qualify, you must be 65 or older by January 1st of the assessment year, own the property, and live in it as your primary residence. There are also income limits—as of recent years, the limit is around $65,000 in household income (this adjusts annually). The application process is straightforward, but you must apply during the correct window, usually in the spring.
For disabled property owners, the Disabled Person Exemption provides an exemption that reduces assessed value. The definition of disability includes physical or mental impairment that substantially limits major life activities, not just mobility issues. Documentation from a physician is required.
Additionally, Illinois offers a Tax Deferral Program for seniors and disabled property owners with limited income. This program allows you to defer property taxes until your property is sold or transferred. While you’ll eventually owe the deferred taxes plus interest, it provides immediate cash flow relief for those on fixed incomes.
Comparing Neighboring Counties
If you’re considering a move within central Illinois, it’s worth comparing Tazewell County property tax rates to neighboring counties. Franklin County property tax rates, Henry County property tax rates, and Sangamon property tax rates all vary significantly. Some neighboring areas have lower effective tax rates, which could save you thousands annually.
However, don’t make a move based solely on tax rates. Consider the total picture: school quality, services provided, home values, and your personal preferences. A county with slightly higher taxes might offer better schools or services that justify the additional cost. That said, if you’re on the border between counties, the tax difference could be substantial enough to influence your decision.
For comparison, Fairfax County personal property tax structures differ from Illinois, and Hunterdon County NJ real estate tax bill calculations follow different state rules entirely. Each state and county has unique systems, so direct comparisons require understanding the underlying assessment methodologies.
Payment Options and Deadlines
Tazewell County property taxes are typically billed twice per year: one bill covers taxes for the first half of the calendar year, and another covers the second half. Payment deadlines are usually in June and September, though exact dates vary by year. Missing a deadline results in penalties and interest charges that compound quickly.
You can pay your Tazewell County property taxes through several methods:
- In Person: Visit the County Treasurer’s office in Pekin during business hours with a check or money order.
- By Mail: Send a check to the Treasurer’s office with your property identification number.
- Online: The County Treasurer may offer online payment options—check their website for current availability.
- Automatic Bank Draft: Set up automatic payments from your bank account to ensure you never miss a deadline.
- Through Your Mortgage Lender: If you have a mortgage, your lender may collect property taxes through escrow and pay them on your behalf.
If your property taxes aren’t paid through escrow and you miss a payment, the county will eventually place a lien on your property. If taxes remain unpaid for several years, the property can be sold at a tax sale to recover the unpaid amount. This is a serious consequence, so prioritize property tax payments in your budget.
Common Mistakes Homeowners Make
After working with dozens of property owners, I’ve noticed patterns in how people mishandle their Tazewell County property taxes. The most common mistake is simply accepting the assessed value without question. Your assessment notice isn’t a final determination—it’s a proposal that you can challenge if you have evidence supporting a lower value.
Another frequent error is missing application deadlines for exemptions. The homestead exemption, senior freeze, and other relief programs have strict filing windows. If you miss the deadline, you typically can’t apply until the next assessment cycle, losing years of potential savings. Mark these dates on your calendar and apply early.
People also fail to document home improvements that increase value for assessment purposes. When you make significant upgrades (new roof, updated electrical, addition), the assessor may increase your assessed value. However, if those improvements aren’t actually completed or permitted, you can challenge the assessment. Keep all contractor receipts and permits.
Additionally, many homeowners don’t realize that property tax bills can be negotiated or that professional help is available. Hiring a property tax consultant or attorney to challenge a significant overvaluation often pays for itself within one year through reduced assessments. This is especially true for commercial properties or homes in the $300,000+ range where assessment errors have larger dollar impacts.
Finally, people sometimes confuse property taxes with homeowners insurance or mortgage payments. These are separate obligations. Your property taxes fund local schools, infrastructure, and services. Understanding this distinction helps you see where your money goes and why the amount matters.

Property taxes in Tazewell County are billed twice yearly, typically with payments due in June and September. The exact dates depend on when the County Treasurer issues bills. Check your tax bill or the Treasurer’s website for current deadlines. If you pay through your mortgage lender’s escrow account, they handle the timing for you.
How often is my property reassessed in Tazewell County?
Your property is reassessed once every three years in Illinois. The assessment year varies by location within the county. You’ll receive a notice before your new assessed value takes effect. Between assessment years, your value remains the same unless you appeal successfully or make major improvements that trigger a reassessment.
Can I appeal my Tazewell County property tax assessment?
Yes, absolutely. You have the right to appeal your assessment if you believe it’s inaccurate. File your appeal with the Board of Review between May 1st and June 30th following the assessment notice. You can appeal by mail or request a hearing. If unsuccessful, you can appeal to the Illinois Property Tax Appeal Board (PTAB) at the state level.
What is the homestead exemption in Illinois?
The homestead exemption reduces the assessed value of your primary residence by up to $6,000 (the exact amount varies). To qualify, you must own the property and live in it as your primary residence on January 1st of the assessment year. You must apply with the assessor’s office—it doesn’t happen automatically. This exemption can reduce your annual tax bill by $200-$400 depending on your local tax rate.
Am I eligible for the Senior Assessment Freeze?
If you’re 65 or older, own your home, live in it as your primary residence, and meet income limits (approximately $65,000 household income), you may qualify for the Senior Assessment Freeze. This program freezes your assessed value at the level from your first year of participation, protecting you from assessment increases. Apply during the spring filing period with the assessor’s office.
What happens if I don’t pay my property taxes?
If you don’t pay your property taxes by the deadline, penalties and interest accrue immediately. After several years of non-payment, the county can place your property in a tax sale, and you could lose ownership. This is a serious consequence. If you’re struggling to pay, contact the County Treasurer about payment plans or look into tax deferral programs if you qualify.
Can I deduct Tazewell County property taxes on my federal income tax return?
Yes, you can deduct state and local property taxes (SALT) on your federal return, but only up to $10,000 per year under current tax law. This deduction is only valuable if you itemize deductions rather than taking the standard deduction. Consult a tax professional to determine whether itemizing makes sense for your situation, as most homeowners now benefit from the standard deduction.
Taking Control of Your Property Tax Bill
Your Tazewell County property tax bill doesn’t have to be a mystery or an unchangeable burden. By understanding how assessments work, applying for available exemptions, and challenging overvalued assessments, you can reduce your tax obligation significantly. Many homeowners leave hundreds or thousands of dollars on the table simply by not taking action.
Start by reviewing your most recent assessment notice. If you haven’t received a homestead exemption, apply immediately. If you believe your assessed value is too high, gather comparable sales data and file an appeal. If you’re a senior or have a disability, investigate relief programs. These steps take time but often result in substantial savings.
Remember that property tax law is complex, and rules vary by location. When in doubt, consult the Tazewell County Assessor’s office, the County Treasurer, or a property tax professional. The investment in professional guidance often pays for itself many times over through reduced assessments and optimized exemptions. Your property is likely your largest asset—protecting it from excessive taxation is a smart financial decision.
