Understanding Form 540

Form 540 is the standard form used for personal income tax returns in California. It is used to report an individual's income, deductions, and credits, as well as to calculate their tax liability. The form is typically filed on an annual basis, with the deadline being April 15th of each year.

Who Needs to File Form 540?

Not everyone is required to file Form 540. Generally, individuals who meet the following criteria need to file:

• Residents of California with a gross income above a certain threshold (currently $15,749 for single filers and $31,498 for joint filers)
• Non-residents who earned income from California sources
• Residents who have self-employment income, regardless of the amount
• Residents who received unemployment compensation

Gathering Required Documents

Before starting the filing process, it's essential to gather all necessary documents. These may include:
