2017 Real Property Delinquent Taxes
On the 1st day of August, 2018, if 2017 real property taxes were still delinquent, a tax lien in the manner provided by law, in the name of Gallatin County, was placed on all delinquent 2017 real property.
Taxpayers have until 5:00 pm August 29, 2018 to redeem said delinquent taxes which will remove Gallatin County's tax lien.
On August 30, 2018, all active 2017 tax liens will be available to be purchased from Gallatin County by a third party. What this means for the taxpayer is addiitional fees will be attached by the third party (i.e. assignment fee, postage, advertising, etc.) for which the taxpayer will need to pay inorder to remove the third party assignment. If no action is taken by the taxpayer prior to September 1, 2021, the third party can start the tax deed process.

Gallatin County Treasurer's Office Information:
- Gallatin County Treasurer's Office sends out delinquent notices as follows:
- Real Property, delinquent notices are sent twice a year - January and late July. It is not beneficial to the taxpayers or Treasurer's Office to send out delinquent notices when there are companies that want to purchase delinquent taxes from the County that send out thousands of notices to taxpayers in early July. This is why the Treasurer's Office waits until late July to send out our delinquent notices.
- Mobile Homes, delinquent notices are sent twice a year - January and July;
- Personal Property, delinquent notices are sent once a year - August.
- Gallatin County Treasurer's Office has started a list of taxpayers email addresses so we can send a reminder to the taxpayer when their taxes are due. By law, the Treasurer's Office sends one (1) tax bill for Real Estate the end of October each year with two (2) stubs due November 30th and the following May 31st, for Mobile Home the end of April each year with two (2) stubs due May 31st and November 30th, and for Personal Property the end of May each year with one (1) stub due June 30th. On the back of your stubs is a line to write your email address so we can
add to our list. You may call or email the Treasurer's Office with your email address also. The Treasurer's Office doesn't sell the email list as it is for our information only.
- By law, the Treasurer's Office can't post partial real estate tax payments. If your payment is received after the due date and penalty & interest is not included, we will return your payment back to you with a notice providing the total amount due and additional time to return the tax payment with penalty and interest to our office.
