Taxes Owed on sale of Rental properties in Texas

Hi,

I'm a California resident and I sold 2 rental properties in Texas this year in July after keeping them 10+ years. Can I wait to pay my taxes on the gains until April of next year or I'll owe penalty. In case If I've to pay penalty how much penalty do I have to pay if my profit is approx 150K. Is there any deadline to pay early taxes on this gain so I don't get any penalty.
