*IMPORTANT NOTE FOR ALL PLAT APPLICANTSPlease be advised for plats to be recorded after September 1, 2021:
If the taxes for 2022 have NOT been calculated, you will need to obtain a 2021 Tax Certificate (showing all taxes are paid in full) and a statement from the Ellis County Tax Office indicating that the taxes have not yet been calculated.

If the taxes for 2022 have already been calculated, you will need to obtain a 2022 Tax Certificate.  This means taxes for 2022 will have to be paid in full prior to your plat being recorded.

This is a requirement of the Property Code, Chapter 12.002.  Please plan accordingly to avoid any potential delays in the recording of your plat.
