TREASURER - FAQ
When are taxes due?
Taxes are due in full December 20th; however, if at least one-half is paid, a grace period extending to June 20th is granted for the second installment.
If the 20th falls on a weekend or legal holiday payments will be accepted as current the next business day.
What happens if my payment is late?
If the first half is not paid on or before December 20th a one-time late charge of 2% on that half will be assessed. Interest begins to accrue on a daily basis beginning January 1st and is calculated based on 1% per month.
If the second half is not paid on or before June 20th a one-time late charge of 2% on that half will be assessed. Interest accrues daily at a rate of 1% per month beginning January 1st on unpaid balances.
Unpaid taxes on personal property and manufactured homes will be sent to the Sheriff’s Office on a “Warrant of Distraint”. Additional costs will be incurred and payment in full will be required. Therefore it is very important that the December and June payments be made on time.
How and where do I pay my taxes?
Taxes may be paid in person at the Treasurer's Office located at 500 N Capital Ave. across from the Assessor's Office.
Office hours are 8:00 a.m. to 5 p.m., Monday through Friday.
Payments may also be mailed to:
Bonneville County Tax Collector
605 N Capital Ave.
Idaho Falls, ID 83402
We accept cash, checks, money orders or cashiers checks. When mailing payments please do so EARLY. Many postal drop boxes have an early pick-up time. Payments made after pick-up times will be postmarked the NEXT day. It is recommended that you mail payments at least a day or two prior to the deadline.
Can I make partial payments or pay in advance?
Partial payments may be made with a minimum of $25.00. Note that payments are applied to the oldest tax first. Advance payments may be made so long as your account is current.
Can I get an extension on my taxes?
Extensions are granted for taxes on personal property and manufactured homes only. However, in order to receive an extension you must call the County Commissioner’s Office before the due date. The maximum extension is four months. Late charges and interest continue to apply. There is no extension granted on the second half of the property tax.
How are taxes calculated?
In simple terms, taxing districts, such as the cities and school districts complete an operating budget each year. The totals of the various budgets are divided by the total property values of their respective geographic areas. The resulting figure is referred to as a levy. This levy is multiplied by the value of your individual property to determine a tax amount. Property values, for purposes of property tax calculations, are determined by the County Assessor’s Office.
The amount of taxes due is ultimately a factor of the combined budgets of the taxing districts. Remember, you have a voice in the amount of tax you pay. Each taxing district is comprised of an elected board that holds a budget hearing every year. These hearings are open to the public for comment. In addition, bonds come up periodically. Taxes are increased or decreased depending upon whether or not these bonds pass or fail.
A list of the taxing districts and levy amounts for the county are available at the Treasurer’s Office.
Regarding assessed values
In May of each year the Assessor’s Office mails out assessment notices stating the value that has been placed upon your property. You have until the fourth Monday in June to appeal the value. If you do not respond by this time the value holds until the following year, when you again will have the opportunity to appeal the value during the stated period.
Tax and Estate sales
Bonneville County may have property for sale under two different circumstances. Either property has been deeded to the county for non-payment of tax or the County Treasurer may sell property as Public Administrator for the estate of a deceased individual(s).
Following is information that addresses common questions regarding the sale of property by the county.
1. Bonneville County does not acquire property on a frequent or regular basis; therefore there are no set times or dates for sale but they will occur whenever the county has property for sale. Although sales are typically held between March and June they could take place other times of the year.
2. Sales will be advertised in the Post Register at least ten days prior to the sale date. Sales will also be posted on this website.
3. Property is sold via live public auction. These auctions are generally held in the Commissioner’s Hearing Room at the county courthouse.
4. Those interested must be present themselves or send a representative. If the interested party cannot be present and is not able to assign a representative, a sealed bid may be submitted prior to the auction. The bid will be opened at the beginning of the auction and will be considered the opening bid. Prior approval from the commissioners is required before submitting a sealed bid.
5. Payment if full is required the day of the sale. Acceptable forms of payment are: cash, cashiers check, money order, personal or bank check. Property will be deeded subject to bank clearance in the case of non-verified funds.
6. All property is sold AS IS with no warranties or representations as to either the condition of the property or liens that may or may not be filed on the property. Interested parties need to do their own research on the property. The property may be physically inspected upon appointment with the County Treasurer.
7. There is no registration required. If interested simply show up (on time).
8. Due to the infrequency of sales, the county does not keep a “list” of properties for sale. As properties are identified as candidates for sale they will be advertized as previously explained.
9. Property on which the taxes are three years delinquent are subject to tax deed. Each November and December a list is published in the Post Register of properties that may be subject to tax deed. It should be noted that most of these will be paid by the end of December.
