Dear Elena, I hope you're having a productive week. Regarding your 2024 California tax return, I've compiled the final figures for you and David. You are filing as 'Married filing jointly'. Your state wages from Form W-2, box 16, were $145,000, and your federal adjusted gross income from your 1040 is $152,000. For adjustments, we are claiming $3,000 in subtractions. You are living at 1245 Maple Street, Apt 4B, San Francisco, CA 94110, and this is indeed your principal residence. Both you and David are under 65, so no senior exemptions are needed. We have two dependents: Sofia (born 2012) and Leo (born 2015), both are your children. Your California withholding for the year totaled $8,500. Regarding the voluntary contributions, let's go ahead and pledge $25 to the California Sea Otter Fund (code 410) and $25 to the State Parks Protection Fund (code 406). I have already checked that you had full-year health care coverage. Please review these figures, and if everything looks correct, let me know so we can authorize the direct deposit of your refund to your primary savings account ending in 9982. Also, let me know if you want me to list myself as your third-party designee for any follow-up questions from the FTB. Best regards, Mark, CPA.
