This guide covers Yellowstone County property tax due dates, penalties, payment options, and resources so you can keep your home safe.
1. Know Yellowstone County Property Tax Due Dates
The Yellowstone County Treasurer collects property taxes in two halves each year:
- First half: November 30
- Second half: May 31
Payments must be received by 5:00 p.m. on the due date to avoid penalties. If you mail your payment, make sure it’s postmarked by the deadline.
Tip: Search “Yellowstone County property tax search” to find your bill and pay online.
2. Understand the Penalties for Late Payment
If you miss a deadline in Yellowstone County:
- Penalty: 2% of the unpaid balance is added immediately.
- Interest: Accrues at 5/6 of 1% per month until the balance is paid in full.
For example, if your second-half property tax bill is $2,000 and you miss the May 31 due date, you’ll owe a $40 penalty plus daily interest.
