Where can I find a California property tax calculator? On a newly purchased property, take the purchase price of your new home times 1.25% (0.0125) to get an estimate of your 1st year's tax bill. If you go to http://www.sunilsethi.com/taxes.htm there are a number of County Assessor's Websites listed that will let you look up your property tax bill online. If you county is not listed, click on
