Payment Deadlines and Penalties

In Idaho, property taxes are due annually, with specific deadlines that homeowners and property owners must adhere to in order to avoid penalties. The state sets a uniform deadline for all counties, which simplifies the process for taxpayers.

Property tax payments are typically due by December 20th of each year. This deadline applies statewide, regardless of the county in which the property is located. Timely payment is crucial to prevent additional charges and legal complications.

If the property tax is not paid by the due date, the county treasurer is authorized to impose penalties and interest on the outstanding balance. These penalties increase over time, emphasizing the importance of prompt payment.

Key points regarding payment deadlines and penalties include:

Property taxes are due on or before December 20th annually.
Payments received after the deadline are subject to a 3% penalty.
Interest accrues monthly on unpaid balances at a rate determined by the Idaho State Tax Commission.
Continued nonpayment can lead to tax lien sales, which may result in loss of property ownership.

Idaho offers several convenient methods for taxpayers to remit their property tax payments. Understanding these options can help ensure timely payment and avoid penalties.

In-Person Payments: Property owners can pay taxes directly at the county treasurer’s office during regular business hours. This method allows for immediate receipt confirmation.

Online Payments: Most counties in Idaho provide online portals where property taxes can be paid using credit or debit cards. Online payments may include a convenience fee.
Payment Plans: Some counties offer payment plan options for qualifying taxpayers facing financial hardship. These plans must be arranged prior to the tax deadline.
