Hello, and welcome to the Montgomery County Treasurer’s website!

As your Treasurer, it is my priority to operate an accessible and efficient office that is fully accountable to YOU, the taxpayers. I hope this website helps you take care of the business you have at hand, in as efficient a manner as possible.

Here you can quickly look up and pay your real estate taxes, set up a monthly prepayment plan to make it easier to tackle your taxes, and find contact information for our departments.

Please do not hesitate to contact me with questions you have or suggestions for how we can better serve you. You can email me at,, or call us at, 937-225-4010.

On behalf of my entire office, I want to thank you for being a part of our community. We are at your service.

My Best,

Russ Smaller

Russ Joseph, Treasurer
