1st half is due by May 15th and Second half is due by October 15th.

To avoid penalty, personal property taxes must be paid in full on or before May 15th. Personal property taxes cannot be paid in first and second half installments unless the property is situated on leased government lands; then the 1st half must be paid on or before May 15th to 2nd half before October 15th.

If you pay your first half and second half property tax after the due dates, a penalty will be added to your tax. The later you pay, the greater the penalty you must pay.
