How Property Tax Works

Power County, Idaho operates on a property tax system that funds essential local services including schools, fire protection, road maintenance, and county operations. Property taxes are the primary revenue source for these services, calculated based on your property's assessed value multiplied by the applicable tax rate for your specific location within the county.

The effective property tax rate in Power County varies significantly by location due to different combinations of special taxing districts. For the 2025 tax year, rates range from approximately 0.949% in rural areas to 1.484% in urban areas, with an average county-wide rate of 1.042%. Your actual rate depends on which school district, fire district, highway district, and other special taxing districts serve your property. These rates are applied to the assessed value of your property, which is typically a percentage of market value as determined by the county assessor.

When Are Property Taxes Due?

For the 2025/2026 tax year in Power County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes are additional property tax bills issued when there's a change in your property's assessed value during the tax year. This most commonly occurs following a change of ownership, completion of new construction, or significant property improvements that increase taxable value.

When supplemental taxes are triggered, the county assessor calculates the difference between your old and new assessed values, then applies the current tax rate to determine the additional tax owed. For example, if you purchase a home in March and the assessed value increases from $250,000 to $350,000, you would owe supplemental taxes on the $100,000 difference, prorated for the remaining months of the tax year (approximately 9 months). Supplemental tax bills are typically mailed within 30-60 days of the triggering event and have their own separate due dates from regular property tax installments.

Section 5

Escrow & Property Taxes

If you have a mortgage, your lender typically collects property taxes through an escrow account as part of your monthly payment. The lender analyzes your annual tax bill and divides it by 12 to determine your monthly escrow portion. Since Power County property taxes are due in two installments (first half by June 20th, second half by June 20th of the following year), your lender will make these payments on your behalf from your accumulated escrow funds.

It's important to review your annual escrow analysis statement to ensure sufficient funds are being collected, especially after property reassessments or rate changes. If your property taxes increase due to rising values or new voter-approved levies, your monthly escrow payment may need adjustment. You can verify that your lender has made tax payments by checking with the Power County Treasurer's office or viewing your account online through the county's payment portal.

Frequently Asked Questions

Q: When are property taxes due in Power County for the current fiscal year? A: Property taxes are due in two installments: first half by June 20th, and second half by June 20th of the following year. Late payments incur penalties and interest charges.

Q: What homeowner tax credits are available and how do I apply? A: The primary homeowner's exemption reduces taxable value by up to $125,000 for owner-occupied homes. You must own and occupy your home on January 1st and apply by April 15th. This credit is not automatic and requires annual application for new homeowners.

Q: How does the homestead credit work? A: Idaho's homestead exemption caps annual assessment increases on your primary residence, limiting year-over-year taxable value growth. This protects against dramatic tax increases from rising property values but requires filing with the county assessor.

Q: Are there additional credits for seniors, veterans, or disabled homeowners? A: Yes, Idaho offers property tax reductions for qualifying seniors (65+), disabled veterans, and disabled homeowners. Each requires separate application with specific income and eligibility requirements. Contact the Power County Assessor for details and applications.

Q: How often are properties reassessed? A: Idaho law requires annual assessment updates to reflect current market values. The Power County Assessor reviews property values each year, with physical inspections conducted on rotating cycles or when triggered by sales or improvements.

Q: How can I appeal my property assessment? A: Assessment appeals must be filed with the Power County Board of Equalization by the fourth Monday in June. You'll need evidence supporting your claim that the assessed value exceeds market value, such as recent comparable sales or professional appraisals.

Q: What penalties apply for late tax payments? A: Late payments incur immediate penalties plus monthly interest charges. The penalty structure starts at 2% and increases over time, with potential tax deed proceedings for severely delinquent accounts.

Q: Can I pay property taxes online? A: Yes, Power County offers online payment options through their official website. You can pay by electronic check or credit card, though credit card payments typically include processing fees.

Q: Why did my tax bill change from last year? A: Tax bills can change due to property value reassessment, new voter-approved levies, changes in special district rates, or loss/gain of exemptions. The largest factor is usually annual value adjustments reflecting current market conditions.

Q: What happens if I disagree with special district charges on my bill? A: Special district taxes (fire, school, highway) are set by their respective boards. Contact the specific district directly for questions about their services or rates. Only the county assessor handles property valuation disputes.
