How Property Tax Works

Shoshone County property taxes fund essential local services including schools, law enforcement, fire protection, roads, and county operations. The county operates under Idaho's property tax system where taxes are calculated based on assessed value multiplied by the applicable tax rate for your specific location. Property owners should understand that actual tax rates vary significantly depending on which special taxing districts serve their property, such as school districts, fire districts, highway districts, and other local service areas.

The effective tax rates for the 2025 levy year are 0.842% for urban areas and 0.544% for rural areas within Shoshone County. However, your individual tax rate may differ based on the combination of special districts that provide services to your specific property location. All property taxes in Shoshone County are administered by the County Assessor's office, with tax bills issued annually based on assessed values as of January 1st each year.

When Are Property Taxes Due?

For the 2025/2026 tax year in Shoshone 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 in Shoshone County are triggered by changes in property ownership, new construction, or improvements that increase assessed value during the tax year. When these events occur after the January 1st assessment date but before the end of the fiscal year, a supplemental tax bill is issued to capture the additional tax liability for the remaining months of the tax year.

The supplemental tax is calculated by determining the difference between the old and new assessed values, applying the current tax rate, and prorating for the remaining months in the tax year. For example, if you complete a $100,000 home addition in July and your tax rate is 0.842%, the supplemental tax would be approximately ($100,000 × 0.842% × 6/12 months) = $421 for the remainder of that tax year. Supplemental bills are typically issued within 60-90 days of the triggering event and have separate due dates from regular property tax bills.

Escrow & Property Taxes

Most mortgage lenders in Shoshone County require property tax escrow accounts to ensure timely payment of property taxes. Your lender will collect approximately 1/12th of your estimated annual tax bill with each monthly mortgage payment, then pay your taxes directly to the county when due. Given Shoshone County's December 20th full payment deadline (or June 20th for first half), lenders typically pay the first half by June 20th and the second half by December 20th.

Your lender will receive a copy of your tax bill and any assessment changes. It's important to review your annual escrow statement and notify your lender of any significant property improvements that might affect your tax liability. If your escrow account has insufficient funds due to increased assessments, your lender may require additional monthly contributions or a lump sum payment to cover the shortage. You can verify payments and view tax records through the Shoshone County Treasurer's office to ensure your lender has made payments correctly.

Frequently Asked Questions

Q: When are property taxes due in Shoshone County for FY 2025-2026? A: Full payment is due by December 20th, or you may pay in two equal halves with the first half due June 20th and the second half due December 20th.

Q: What tax credits are available and do they require application? A: The primary credit is the Homeowner's Exemption under Idaho Code 63-602G, which requires annual application to the Shoshone County Assessor's office. You must be an Idaho resident and the property must be your primary dwelling. Applications must be received before the required deadline.

Q: How does the Homeowner's Exemption work? A: The Homeowner's Exemption reduces your taxable assessed value, not your market value. It requires application and is not automatic. Contact Assessor Jerry White's office at (208) 752-1264 for current exemption amounts and application deadlines.

Q: When are properties assessed and how can I appeal? A: Properties are assessed as of January 1st each year. Assessment notices are typically mailed in April. You have until the fourth Monday in June to file an appeal with the Shoshone County Board of Equalization.

Q: What are the penalties for late payment? A: Idaho law imposes penalties and interest on delinquent property taxes. Contact the Shoshone County Treasurer for current penalty rates and payment options.

Q: Can I pay property taxes online? A: Contact the Shoshone County Treasurer's office for current online payment options and accepted payment methods.

Q: Why do properties in different areas of Shoshone County have different tax rates? A: Tax rates vary based on special taxing districts that serve your property, such as different school districts, fire districts, and highway districts. Urban areas (0.842%) and rural areas (0.544%) have different service needs and district combinations.

Q: How do special district taxes affect my bill? A: Special districts provide specific services like fire protection, schools, or road maintenance. Your property's location determines which districts serve you, and each district adds its levy rate to your total tax rate. The Assessor's office can provide a breakdown of districts serving your specific parcel.
