California 2017 State Income Tax Brackets Released... Will you need to pay the statetaxman?
Most single people under 65 years old with no dependents would not need to file a tax return unless they have adjusted gross income of $13,623 or more in 2016. For most taxpayers filing married filing jointly and under 65 years old, the threshold is $27,249. However, these individuals should still file if they are due a refund or are eligible for the Earned Income Tax Credit.
