Real Estate Property Tax Information
Tax bills are mailed approximately the last week of October every year. You will receive only one bill for the tax year. Notices or reminders are not mailed for the second-half payments. You are billed for the current year. If your taxes are paid by a lending agency, the lending agency has also received a copy of the tax bill.
If you did not receive a tax bill or you need to change your mailing address, please contact the County Assessor's Office for correction 406-497-6290.
Failure to receive a property tax statement does not exempt the taxpayer from the payment due dates.
A paid receipt will not be mailed back to the tax payer unless you include a self-addressed stamped envelope with your payment. Normally, if you pay by check, your check is considered your receipt. If you make your payment in our office, a receipt is provided. You may obtain a copy of your tax payment at anytime by calling the office at 406-497-6303 or in person at 155 West Granite Street Room 206, Butte, Montana.
Real estate property due dates:
- The first half-payment is due on or before November 30 of the current year
- The second half-payment is due on or before May 31 of the following year
- Full-year payments may be paid at one time on or before November 30 of the current year if desired
You must pay taxes as billed. No partial payments will be accepted. Taxes may be paid in two installments as noted above. If the first installment is not paid by November 30 of the current year, then the amount of the first installment only becomes delinquent. If the second installment is not paid on or before May 31, the following year, then the amount of the second installment becomes delinquent.
When either installment becomes delinquent, a penalty of 2% is added. Interest will accrue at the rate of 10% per annum. This will apply to each year the tax is delinquent. If the entire year billed becomes delinquent (meaning both halves are not paid by May 31), then the full year must be paid with penalty and interest. No payments are accepted in installments after this date.
Delinquent real estate taxes may be subject to tax lien purchase. If a delinquency exists, please contact the Treasurer's Office at 406-497-6310 to ensure the correct payment. Please refer to Montana State law, MCA 15-16-102 for more information.
