As a senior receiving social security benefits, am i eligible for a stimulus check from the CARES act using my SSA-1099 or do i need to file a tax return?

See this IRS website for information - https://www.irs.gov/newsroom/economic-impact-payments-what-you-need-to-know

The IRS does not have my direct deposit information. What can I do?

In the coming weeks, Treasury plans to develop a web-based portal for individuals to provide their banking information to the IRS online, so that individuals can receive payments immediately as opposed to checks in the mail.

I am not typically required to file a tax return. Can I still receive my payment?

Yes. People who typically do not file a tax return will need to file a simple tax return to receive an economic impact payment. Low-income taxpayers, senior citizens, Social Security recipients, some veterans and individuals with disabilities who are otherwise not required to file a tax return will not owe tax.

How can I file the tax return needed to receive my economic impact payment?

IRS.gov/coronavirus will soon provide information instructing people in these groups on how to file a 2019 tax return with simple, but necessary, information including their filing status, number of dependents and direct deposit bank account information.
