2020 Instructions for Schedule X California Explanation of Amended Return Changes

References in these instructions are to the Internal Revenue Code (IRC) as of January 1, 2015, and to the California Revenue and Taxation Code (R&TC).

What's New

Dependent Exemption Credit with No ID – For taxable years beginning on or after January 1, 2018, taxpayers claiming a dependent exemption credit for a dependent who is ineligible for a Social Security Number (SSN) and a federal Individual Taxpayer Identification Number (ITIN) may provide alternative information to the Franchise Tax Board (FTB) to identify the dependent. To claim the dependent exemption credit, taxpayers complete form FTB 3568, Alternative Identifying Information for the Dependent Exemption Credit, attach the form and required documentation to their tax return, and write “no id” in the SSN field of line 10, Dependents, on Form 540, California Resident Income Tax Return, or Form 540NR, California Nonresident or Part-Year Resident Income Tax Return, or of line 8, Dependents, on Form 540 2EZ, California Resident Income Tax Return. For each dependent being claimed that does not have an SSN and an ITIN, a form FTB 3568 must be provided along with supporting documentation.

Taxpayers may amend their 2018 and 2019 tax returns to claim the dependent exemption credit. For more information on how to amend your tax returns, see Schedule X, California Explanation of Amended Return Changes, Specific Line Instructions, Part II, Reason(s) for Amending, and get 540 or 540 2EZ, Personal Income Tax Booklet, or 540NR, Nonresident or Part-Year Resident Booklet.

Expansion for Credits Eligibility - For taxable years beginning on or after January 1, 2020, California expanded Earned Income Tax Credit (EITC) and Young Child Tax Credit (YCTC) eligibility to allow either the federal ITIN or SSN to be used by all eligible individuals, their spouses, and qualifying children. If an ITIN is used, eligible individuals must provide identifying documents upon request of the FTB. Any valid SSN can be used, not only those that are valid for work. Additionally, upon receiving a valid SSN, the individual should notify the FTB in the time and manner prescribed by the FTB. The YCTC is available if the eligible individual or spouse has a qualifying child younger than six years old. For more information, get form FTB 3514, California Earned Income Tax Credit, and go to ftb.ca.gov and search for eitc.

Dependent Exemption Credit with No ID – If you are amending a return to claim the dependent exemption credit for tax years 2018 and 2019, complete an amended Form 540, Form 540NR, or Form 540 2EZ, and write "no id" in the SSN field on the Dependents line, and attach Schedule X. To complete Schedule X, check box m for "Other" on Part II, line 1, and write the explanation “Claim dependent exemption credit with no id and form FTB 3568 is attached” on Part II, line 2. Make sure to attach form FTB 3568 and the required supporting documents in addition to the amended return and Schedule X.
