when will I  receive my California state tax return by mail if my refund was issued on May ,01,2025.


If the CA state tax refund website indicates it was issued - https://www.ftb.ca.gov/refund/index.asp

You will have to contact the FTB if the refund was mailed and you have not received the check in the mail - https://www.ftb.ca.gov/help/contact/index.html
