Your optimum tax rate is 36%. Stop building farms for a while and focus exclusively on construction sites. Store turns at 99 turns played so as not to exit protection early. Next time you get around to building, build an oil rig to further reduce the risk of an earthquake by introducing the potential for an oil fire.

Finally, for future reference, it's ideal to wait as long as possible to play the first hundred turns because the daily 20 acre logon bonus increases your income substantially over those first hundred turns.

Gotta love how the status uploader omits the land value :)
