Im in California, if I claim my mother of 79 years old, as a dependant, Will this affect my mother's social security, SSI, Food Stamps, medicaid, and medicare?

Claiming someone as your dependent will have no affect on their Medicare or Social Security benefits. 

However, you will need to contact your local Medicaid office to find out if claiming her as your dependent will affect any state aid she receives, such as Medicaid and Food Stamps.  States pay the Medicare premiums for people who receive SSI benefits if they are also eligible for Medicaid.

If you claim your mother as a dependent, that means you are certifying to the IRS that even after considering all sources of financial support that your mother receives (including Social Security, Medicare, SSI, and Medicaid) that you pay more than half her living expenses.  Is that actually true in this case?

This is an income tax form and we will not be knowledgeable about the qualification and eligibility rules for SSI and Medicaid in every state. SSI and Medicaid are based on a persons financial need, and if you are declaring that you are supporting your parent, they may have less financial need. The California tax department (FTB) is certainly allowed to share your tax information with other state agencies, such as for verification of financial need.

Just so you know----when you claim a parent as your dependent, all you "get" is the $500 credit for other dependents for your own tax return.  Sometimes people expect more than that-----the days of getting a personal exemption for claiming a parent ended with the tax laws that changed for 2018 and beyond.    So consider carefully if claiming your parent will affect her eligibility to receive other benefits.   And.....she will not be eligible to get any possible future federal stimulus checks since dependents are not eligible for stimulus money.     Congress has not passed any new stimulus payments, and we do not know if they will, but.....
