Tax Payments

P.O. Box 1010 Caldwell, ID 83606 When you pay by check you authorize us to process your payment electronically. Funds may be withdrawn from your account as soon as the same day we receive your payment. You will not receive your original check back from your financial institution: however an image of the check will be available from your financial institution. Payments mailed for the first half taxes must be postmarked on or before December 20th and have a US Postal cancellation mark to be considered current. The grace period for the second half ends on June 20th of the following year. A postage meter is not an acceptable postal cancellation. If the first half of Personal Property or Manufactured Housing is not paid by December 20th that half becomes delinquent and the ENTIRE TAX BECOMES DUE IN FULL. Transient Personal Property and Occupancy Tax is due by March 20th. If the first half is not paid on or before December 20th, that half becomes delinquent and a 2% late charge shall be added.  Interest on the delinquent tax and late charge is calculated at the rate of 1% per month beginning January 1st of that year.  If the first half tax is paid in part, late charge and interest is calculated on the remaining tax. Per Idaho code 63-902(9), the fact you do not receive a tax notice on any property does not excuse you from the taxes or late charge and interest for non-payment. If you have closed a business during the year, purchased property or believe you have not received all your tax notices, please call 208-454-7354 to inquire.

Any portion of a property tax may be paid at any time, however, to avoid late charge and interest, total payment must be made in full by the due date.  Partial payment of any tax will not invalidate any collection process.

Canyon County property owners can pay their tax bills BY PHONE using a debit/credit card by calling 1-208-718-5186.  You MUST have your bill number printed on your tax statement ready when calling.  There is a convenience fee of $1.50 plus 2.39%.  No part of this fee is retained by Canyon County.

The Treasurer’s Office can accept credit card payments in office or online at the Canyon County Online Tax Payment page This is a secure external website hosted by Billing Documents Specialists. You will need your 10-character PIN number, located on your annual tax notice to use this service. A convenience fee of 2.39%, or a $2.00 minimum fee, is charged by the credit card processor on all payments made using your credit card (both online & in person). Debit cards are also accepted at a 1% fee. E-Checks (online only) are a $1.00 fee. No part of these fees are retained by Canyon County.

The taxpayer must notify the Assessor’s Office of any mailing address changes. Your annual tax notice will be mailed no later than the 4th Monday in November. If you do not receive a notice by the end of the month, you should contact our office immediately.
Know the annual tax due dates: December 20th and June 20th. The taxpayer should know if they are responsible to pay the taxes or if their lender intends to pay the annual tax.  If you have recently refinanced, review your loan documentation to determine how the taxes were handled at closing. If you are still not clear who should be paying the tax, please contact the title company or your lender.
Important – Per Idaho code 63-902(9) the fact that you do not receive a tax notice on any property does not excuse you from the tax or associated late charge and/or interest for non-payment. If you have closed a business during the year, purchased property, or believe you have not received all your tax notices, please call (208) 454-7354.
