California's Franchise Tax Board makes available tax tables and charts for Forms 540, 540A, 540NR and 540EZ at its website, FTB.ca.gov. Tax liabilities are based on income and on the taxpayer's filing status as single, married or head of household, notes the FTB.
Taxpayers can access tax tables for all versions of Form 540 in either PDF or HTML formats. Tax tables are presented according to year, with tables for tax years 2011 through 2014 accessible by click-through at the FTB website, as of 2015. Also available is information about tax rates and exemptions for individuals and businesses for those years as well as tax year 2015, according to the FTB. The FTB also provides a tax calculator on the site.
