Form 540 is used to report your California taxable income to the Franchise Tax Board and calculate state tax owed or refunded. Despite occasional searches for "IRS Form 540," it's a state return, not a federal one; the IRS uses Form 1040 instead.
Full-year California residents who meet the state's income tax filing requirements and do not qualify for the simpler Form 540 2EZ should use this form. The Form 540 filing requirements depend on factors such as income, filing status, age, and dependents. Nonresidents and part-year residents generally use Form 540NR instead.
The Form 540 due date is April 15 each year, matching the federal deadline. If you need more time, California grants an automatic six-month filing extension to October 15, though any tax owed is still due by the April deadline to avoid interest.
If the form isn’t submitted, this triggers late-filing Form 540 penalties of up to 25% of the unpaid tax, plus interest. If the return is more than 60 days late, the minimum penalty is $135 or 100% of the unpaid tax, whichever is less, and unpaid amounts may continue to accrue interest until paid.
You should e-file your Form 540 for California return through CalFile or approved software, or follow the official Form 540 instructions to file by mail. Refunds or no-balance-due returns go to different Sacramento addresses, both listed on the FTB site.
