What California Form 540NR (2020) Is For
California Form 540NR (2020) applies to individuals who did not live in California for the entire 2020 tax year. This includes part-year residents who moved into or out of California and nonresidents who earned California-source income.
The form ensures proper reporting under California income tax rules for mixed residency and California-sourced income. This return applies only to income from California sources, unlike Form 540 for full-year residents.
You must complete Schedule CA to report California adjustments and accurately calculate taxable income. This part-year resident income tax return complies with California tax rules for nonresidents and aligns with other required forms.
When You’d Use California Form 540NR (2020)
File California Form 540NR (2020) if you earned California income while living elsewhere or changed your California residency status. You must file if your gross income exceeds the threshold based on your filing status, age, and dependents.
This form supports the proper filing process for nonresidents and part-year California residents. You may also use it to claim a refund when California tax was wrongly withheld on a nonresident return.
Attach Schedule X if you need to amend a prior state return for the same taxable year. If Form 593 shows real estate withholding, report that amount on your return as part of your tax payments.
Key Rules or Details for 2020
For tax year 2020, several California-specific rules affected nonresident and part-year resident tax returns. You could not deduct net operating losses if your modified adjusted gross income were $1 million or more.
This suspension applies to individuals and entities filing a Limited Liability Company Return of Income. California also did not conform to the federal income tax exclusion for forgiven Paycheck Protection Program loans.
Certain COVID-19 relief grants, including rent forgiveness and small business support, were excluded from California taxable income. Always review FTB guidance before applying tax benefits, including the Child and Dependent Care Expenses Credit.

Common Mistakes and How to Avoid Them
Taxpayers experience processing delays because filings contain preventable procedural mistakes. Identifying errors improves filing accuracy and supports acceptance by the California Franchise Tax Board. Following the correct steps helps you submit a complete and compliant return.
- Incorrect Residency Classification: This mistake occurs when you enter incorrect residency dates. You must verify dates using FTB Pub 1031.
- Missing Schedule CA: This mistake occurs when Schedule CA is not included in your filing. You must attach the schedule to calculate taxable income.
- Unreported Form 593 Withholding: This mistake occurs when you exclude California real estate withholding. You must report the amount shown on Form 593.
- Mismatched Social Security Number: This mistake occurs when the number does not match official records. You must verify accuracy on every form.
- Incorrect Credit Claims: This mistake occurs when you claim ineligible credits. You must confirm eligibility before filing.
What Happens After You File
After submission, the Franchise Tax Board reviews your return and matches reported figures against official payer records. They review California adjusted gross income, withholding, and tax liability for consistency with W-2s, 1099s, and filed information.
E-filed returns process faster than paper ones and support quicker verification of part-year taxes and tax credit claims. If a refund is due, you will receive payment by direct deposit or check after verification is complete and the processing cycle is completed.
When additional tax is owed, you receive a notice reflecting updated balances, interest, and assessed tax liability amounts from the state records. The Franchise Tax Board may request documents to verify California Earned Income Tax Credit claims or reported residency details.
