Tax Collection


First Half Tax deadline was extended to December 27, 2022. Tax payments post-marked, dropped-off in our drop box, paid online or in-person by this date are considered paid on time.

If the first half of your Personal Property was not paid  as of December 31, 2022, it is now due in full, including penalties and fees.

Please contact us for updated amount due now that payments are delinquent.

ONLINE PAYMENTS can be made with a debit or credit card for an additional fee.

Real Estate Tax information can also be found on our county website tax parcel search. Payments can be mailed, placed in the drop box outside the courthouse, in person or online.

The County Treasurer's Office by state law is responsible for the tax billing, collection, and distribution of tax money for the State, County, Cities, and all other taxing entities that levy Ad Valorem and/or special assessment taxes. 

We are open on a walk-in basis currently with no appointment required for tax payments but if an appointment works best for you, feel free to contact us and we will schedule a convenient time for you.

Tax payments can be paid via cash, check, or debit or credit card with an additional processing fee, however we cannot accept this information over the phone or via mail or email.

Tax Statements

Tax statements are mailed in November of each year. Taxpayers have the option of paying the full or first half amount by December 20th; the last half is due by May 10th of the following year.

Tax Roll Corrections

All tax bill corrections are issued by the Osage County Appraiser. The County Clerk's office receives this information and issues a corrected real estate or personal property tax statement. Reductions will be reflected on the second half payment if taxes are not paid in full. Fully paid taxes with a reduction may create an overage resulting in a refund.

  1. Real Estate

If the first half tax due is unpaid as of December 21st, interest calculates daily and becomes due. Additional penalties and fees may become due and payable based on the date paid. 

After May 10th of the following year, the full tax amount plus interest, penalties, and fees is due. We do not mail out second half tax statements.

The Real Estate Tax Statement you receive in November includes two payment stubs at the bottom, as shown here. These can be removed and included with your mail-in payment or brought in for in-person payments. These include the tax year and the tax payment due dates for both first and second half taxes.
