Steps to Determine Filing Requirement

If you are a nonresident of California and received income in 2021 with sources in California, go to Step 1. For more details see How Nonresidents and Part-Year Residents Are Taxed.

Step 1: Is your gross income (gross income is computed under California law and consists of all income received from all sources in the form of money, goods, property, and services, that are not exempt from tax) more than the amount shown in the California Gross Income chart below for your filing status, age, and number of dependents? If yes, you have a filing requirement. If no, go to Step 2.

Step 3: If your income is less than the amounts on the chart you may still have a filing requirement. See “Requirements for Children with Investment Income” and “Other Situations When You Must File.” Do those instructions apply to you? If yes, you have a filing requirement. If no, go to step 4.

Step 4: Are you married/RDP filing separately with separate property income? If no, you do not have a filing requirement. If yes, prepare a tax return. If you owe tax, you have a filing requirement.

Requirements for Children with Investment Income

California law conforms to federal law which allows parents’ election to report a child’s interest and dividend income from children under age 19 or a student under age 24 on the parent’s tax return. For each child under age 19 and student under age 24 who received more than $2,200 of investment income in 2021, complete Form 540NR and form FTB 3800, Tax Computation for Certain Children with Unearned Income, to figure the tax on a separate Form 540NR for your child.

If you qualify, you may elect to report your child’s income of $11,000 or less (but not less than $1,100) on your return by completing form FTB 3803, Parents’ Election to Report Child’s Interest and Dividends. To make this election, your child’s income must be only from interest and/or dividends. See “Order Forms and Publications” or go to ftb.ca.gov/forms.

Other Situations When You Must File

If you have a tax liability for 2021 or owe any of the following taxes for 2021, you must file Form 540NR.

Filing Status

Use the same filing status for California that you used for your federal income tax return, unless you are an RDP. If you are an RDP and file single for federal, you must file married/RDP filing jointly or married/RDP filing separately for California. If you are an RDP and file head of household for federal purposes, you may file head of household for California purposes only if you meet the requirements to be considered unmarried or considered not in a domestic partnership.

Exception: If you file a joint tax return for federal, you may file separately for California if either spouse was either of the following:

If you had no federal filing requirement, use the same filing status for California you would have used to file a federal income tax return.

Single

You are single if any of the following is true on December 31, 2021:

Married/RDP Filing Jointly

You may file married/RDP filing jointly if any of the following is true:

Married/RDP Filing Separately

Head of Household

For the specific requirements that must be met to qualify for head of household (HOH) filing status, get FTB Pub. 1540, Tax Information for Head of Household Filing Status. In general, HOH filing status is for unmarried individuals and certain married individuals or RDPs living apart who provide a home for a specified relative. You may be entitled to use HOH filing status if all of the following apply:

For a child to qualify as your foster child for HOH purposes, the child must either be placed with you by an authorized placement agency or by order of a court.

California requires taxpayers who use HOH filing status to file form FTB 3532, Head of Household Filing Status Schedule, to report how the HOH filing status was determined.

Beginning in tax year 2018, if you do not attach a completed form FTB 3532 to your tax return, we will deny your HOH filing status. For more information about the HOH filing requirements, go to ftb.ca.gov and search for hoh. To get form FTB 3532, see “Order Forms and Publications” or go to ftb.ca.gov/forms.
