The Internal Revenue Service (IRS) has confirmed that even people who typically do not file a tax return will need to file 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 but must still file a return with the IRS. The IRS is developing a simplified form that should become available very soon.
Here is an excerpt from the IRS website:
If you filed a 2018 or 2019 tax return you will automatically receive a stimulus check.
However, if you did not file a tax return you can still get a check. To do so you will need to complete a simplified tax return which will be available shortly.
