Pay property tax (full or first half) by December 31. Oklahoma property tax bills are due November 1, and unless at least half is paid by December 31 the whole year's tax becomes delinquent on January 1 and accrues interest of 1.5% per month, so paying in full or paying the first half by December 31 (with the second half due by March 31) avoids that interest.
Pay second-half property tax by March 31. If you paid only the first half of your Oklahoma property tax by December 31, the second half must be paid by March 31, or it becomes delinquent on April 1 and accrues interest of 1.5% per month.
