Option 2
Disclaimer: Modifications of mortgage may require special calculation. Because there may be prior mortgage tax payments, increases in money, or other factors to take into consideration, you may not be able to use the calculation methods indicated above. If you are unsure of how to calculate mortgage tax on a modification, it is best to contact our office for assistance.

Please call one of the numbers below for assistance:
(918) 596-5063 (voice mail option), 596-5069, 596-5068, 596-5049, or 596-5036

Note:  If you are filing a modification of mortgage and no additional mortgage tax is due, you do not need to pay the $5.00 certification fee.  The document will be stamped “No Mortgage Tax Due” and will be forwarded to the county clerk’s office for filing.

To calculate the tax manually:
Take the amount of the mortgage, divide it by one hundred, and multiply it by the appropriate rate.  Mortgages not evenly divisible by 100 must be rounded up to the nearest 100 before the calculation is made.  Rates are determined by the term of the mortgage.

Example 1 (No rounding necessary):

 A $50,000.00 mortgage for 30 years would be calculated as follows: 

            50,000

               100               X         0.10 = $50.00 in mortgage tax due.

 Example 2 (Amount of mortgage rounded up):

 A $50,250.00 mortgage for less than 2 years would be calculated as follows:

             50,300

               100               X         0.02 = $10.06 in mortgage tax due.

 IN ADDITION TO MORTGAGE TAX, THERE IS A $5.00 CERTIFICATION FEE DUE TO THE TREASURER.  PLEASE INCLUDE THE $5.00 CERTIFICATION FEE WHEN PAYMENT IS REMITTED.
