Whether you’re a first time homebuyer in Idaho Falls or a long-time resident of Rigby, understanding property taxes in Bonneville County is essential. These taxes fund vital community services like schools, law enforcement, and infrastructure, and they also play a big role in your total cost of homeownership. This guide breaks down everything you need to know about Bonneville County property taxes so you can stay informed and avoid surprises at tax time.
What Exactly Are Property Taxes?
Property taxes are charges assessed on real estate owners by local government entities including the county, cities, school districts, and special service districts. The funds collected support essential public services such as law enforcement, fire protection, public education, and road maintenance.
In Bonneville County your property tax bill includes contributions to several taxing bodies including Bonneville County government, your local city government if applicable, your school district, and other special districts that provide local services such as water, sewer, landfill, or library services.
How Much Is Property Tax in Bonneville County?
Each year the Bonneville County Assessor’s Office determines the market value of your property as of January 1. That value, less any applicable exemptions, becomes your taxable value. Then the levy rates set by the various taxing districts in your area are applied to calculate the total tax amount owed.
In Bonneville County the median property tax is about $1,211 per year for a home with a median value of $153,400, which corresponds to an effective tax rate of about 0.79% of the home’s value.
Your actual tax will depend on your property’s assessed value, the taxing district levies in your area, any exemptions you apply for, and recent improvements to your property.
When Are Property Taxes Due in Bonneville County?
Property taxes in Bonneville County are billed annually. Important deadlines to note: The full year tax is payable on or before December 20. Alternatively you may pay in two halves: the first half by December 20 and the second half by June 20 of the following year. If the first half is not paid timely a 2% late charge is added and interest begins to accrue at 1% per month starting January 1 of the following year. If the second half is not paid by June 20 it becomes delinquent and the same late charge and interest rules apply.
When Will You Receive Your Property Tax Bill?
In Bonneville County tax bills or notices are typically mailed in November each year. Even if you do not receive your bill you are still responsible for paying your taxes on time. You can view your bill, check your balance, and make payments via the County Treasurer’s online payment portal.
What Happens If You Miss the Bonneville County Property Tax Due Date?
If you fail to pay your taxes by the due date a late charge and interest begin to accrue. Continued non-payment may result in further collection actions including lien filings or tax deed processes. It is very important to stay ahead of the deadlines or verify your mortgage escrow is paying the taxes on your behalf.

- Online payments via the treasurer’s portal using debit, credit or e-check (note that processing fees may apply)
- Payment by mail to the Treasurer’s Office at the address shown on your tax bill

What Should I Know About My Bonneville County Property Tax Bill?
Your tax bill includes a detailed breakdown of your property’s assessed value, taxable value after exemptions, and the levy rates from each taxing district that contribute to your total tax amount. The County also publishes levy rate schedules and tax code area maps so you can review how your tax is calculated. If your bill does not arrive or if you have questions about amounts owed you should contact the Bonneville County Treasurer’s Office.
Property Tax Reassessments in Bonneville County
The Bonneville County Assessor’s Office reviews and assesses taxable property each year, using a market value date of January 1. Assessment notices are mailed in accordance with Idaho law and you will have an opportunity to appeal your assessed value via the Board of Equalization if you believe the value is incorrect.
While Idaho law does not impose a cap on how much the assessed value of an individual property may increase, local taxing districts are subject to budget growth limitations (often around 3 percent plus new construction or annexation additions) which can help limit levy increases.
Frequently Asked Questions
What if I don’t receive my tax bill?
You are still responsible for paying on time. Visit the County Treasurer’s website to view or pay your bill, or contact the Treasurer’s office to request a duplicate.
Is there a limit on how much property taxes can increase?
Idaho law limits local taxing districts’ budget increases to about 3 percent plus new construction and annexation, however your individual tax bill may still increase if your property’s assessed value rises, new levies are approved, or property improvements are made.
What happens if I don’t pay my property taxes on time?
A late charge (typically 2 percent) is applied and interest accrues at about 1 percent per month beginning the year following the delinquency. If taxes remain unpaid for multiple years the County may initiate tax deed or lien sale processes, which can put your property ownership at risk.
