Payments mailed for the 1st half tax must be postmarked on or before December 20th and have a US Postal cancellation mark to be considered current. A postage meter is not an acceptable postal cancellation.
If the first half is not paid on or before December 20th, it becomes delinquent, and a 2% late charge shall be added.

If the first half tax is paid in part, late charge and interest is calculated on the remaining tax due.
Per Idaho code 63-902(9) the fact you do not receive a tax notice on any property does not excuse you from the tax or late charge and interest for non-payment.

Understanding Property Tax Relief in Canyon County
Due to recent legislative changes, property tax relief in Idaho continues to evolve. Here are the changes in 2024:
- School District Facility Fund (SDFF): State funds help reduce school district bonds, supplemental, and plant facility levies on property tax bills. Additional state revenue has been allocated for 2024.
- Homeowner Tax Relief (HTR): Credits were applied to all properties receiving a Homeowner’s Exemption. The H/O Exemption must be in effect before the 2nd Monday in July. A reduction in state revenue has lowered the credit amount for 2024.

Property tax is determined from the budget needs of each taxing district. Several kinds of taxing districts exist in Idaho. Levy taxes provide a wide range of services within the city and/or county. Other levy taxes are for specific purposes like highways, schools, and fire protection. Officials for each taxing district determine the annual budget needed to provide the district’s services. The approved budget to be funded by the property tax is divided by the total taxable value of all properties within the district. This determines the tax levy rate. This tax levy rate is multiplied by the taxable value of the property to determine the amount of tax you owe.
Tax levy rates can be affected by a variety of factors which include the taxing district’s emergency needs or voter approved bonds and override levies.
Levy rates are certified by the state by the end of October of each year.
Property Tax Fraud – SCAM
Identifying Fraudulent Property Tax Letters in Canyon County
Recently, a Canyon County resident brought a suspicious letter to our Treasurer’s office, raising concerns about potential property tax fraud and scams in the area. With the rise in fraudulent tax communications, it’s important to know how to recognize whether a letter is legitimate or a scam. Here are some key tips for Canyon County residents to help differentiate between a real letter from the Idaho State Tax Commission and a fake one.
Legitimate Tax Letters from Canyon County
- Official Letterhead: Any letter from the Idaho State Tax Commission or Canyon County Treasurer’s office will clearly display the agency’s name in the top left corner. For local tax-related matters, look for “Canyon County Treasurer” on the letter.
- Letter ID or Reference Number: Real tax letters will include a unique letter ID or a reference number that identifies the specific document. This helps verify the letter’s legitimacy.
- Local Contact Information: At the bottom of the letter, you will always find clear contact details, including our helpline or the specific office that sent the letter. Canyon County Treasurer’s office contact information will include local phone numbers and email addresses specific to the department.
Red Flags in Fraudulent Letters
Scammers often create letters that mimic official tax communications, but there are signs that can help you identify a fake letter. Here’s what the Canyon County resident’s fraudulent letter revealed, and what you should watch for:
- Vague or Suspicious Terminology: Fraudulent letters often use terms like “Tax Processing Unit” or other vague phrases that sound official but aren’t used by legitimate agencies. Scammers use these terms to intimidate and pressure you into responding quickly.
- Lack of Specific Information: Scam letters may mention general terms like “tax liability” but fail to specify what kind of tax, what property is affected, or any details about the issue. Official letters from Canyon County will always be clear and specific.
- Errors in Spelling and Grammar: Pay attention to any spelling, grammar, or capitalization errors in the letter. Legitimate letters from our office or the Idaho State Tax Commission are professionally written.
- Unfamiliar Phone Numbers: Be cautious of any phone numbers provided in suspicious letters. Before calling, search the number online or visit the Canyon County Treasurer’s website to verify it. If the number doesn’t match our official contact details, it could be a scam.
- Unclear Requests: Scam letters might be vague about what they’re asking you to do, or they might request immediate action without offering clear instructions. If a letter is confusing or seems off, take a moment to verify its authenticity.
What You Can Do If You’re Unsure
If you ever receive a letter that you’re unsure about, follow these steps:
- Verify the Contact Information: Look up the Canyon County Treasurer’s office or the Idaho State Tax Commission directly, and contact us using the phone number or email listed on our official website.
