Tax Collection


If you have delinquent real estate taxes from 2019 or prior, your property is eligible for the next county tax sale. Letters were mailed to notify property owners and allow time to make payments accordingly. 

Please contact us for an updated amount due as penalties and interest accrue daily.

Online payments can be made with a debit/credit card or e-Check for an additional fee - click the link below:


eCheck is a flat $2.95 fee for transactions up to $99,999.99.

Debit/Credit cards are a percentage of the total payment amount.

    • You will need to enter code a001OS
    • We ask that you include a parcel or statement number, or NAMEID as the TaxID with your payment so it may be applied properly and timely.

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.

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.
