Like the Government Accountability Office (GAO) report, Collins noted how dead people received stimulus checks. (The new report said the IRS issued 965,000 checks, compared the 1.1 million checks counted by the GAO.)

It’s “unclear what the IRS will do” if taxpayers don’t return stimulus payments, Collins said in a footnote. If the IRS had information someone was dead and still paid stimulus money.

“However, if the IRS made the payment despite having information in its possession that the individual was in fact deceased, the National Taxpayer Advocate recommends the IRS not spend its resources pursuing enforcement actions against a decedent’s estate or a family member who received an EIP for a decedent,” she added.

The GAO report last week said the IRS had access to Social Security Administration death records, but didn’t use them when distributing the first three batches of stimulus checks.

Incarcerated Americans are also receiving stimulus money

Though the IRS says incarcerated individuals need to return the money — just like the relatives of dead people who receive checks — the watchdog office says the tax collector ought to be more specific about which people need to return the money.

“A situation could arise where a taxpayer was incarcerated at the beginning of 2020, but was released in the midst of the pandemic — especially since a number of incarcerated individuals were released to mitigate the spread of COVID-19 in the country’s prison system,” Collins noted.

Nearly 96,000 people have been released from prisons and jails in the wake of the outbreak, according to a University of California, Los Angles law school database.

The open questions on return rules for incarcerated individuals are one example of the wrinkles when the IRS distributed approximately 160 million direct stimulus payments under the Coronavirus Aid, Relief, and Economic Security (CARES) Act.

“While the IRS did an impressive job implementing the provisions of the — particularly under these unprecedented circumstances — there have been several issues in implementing the CARES Act’s most significant provisions,” the report said.

The IRS may have to learn from any missteps quickly and gear up for a second round of direct checks soon. Lawmakers are considering another stimulus bill and Treasury Secretary Steven Mnuchin has said a relief package could materialize next month.

Benefits information didn’t reflect if certain Social Security and veterans’ benefits recipients had dependents who could qualify for the $500, the report said. The IRS gave a May 5 deadline for these people to add information about children and get the extra money.

Though Collins said “these financially-strapped individuals” could always claim the dependents in their 2020 tax returns, that’s a long way from now. IRS should continue to let them update their information and get the stimulus money for dependents, she said.

The GAO report also noted the issue about missed money for dependents. Approximately 450,000 stimulus-check recipients didn’t get extra money for dependents in their stimulus payments, the report said. The IRS is finding the accounts and adding the extra payments by the end of next month, the GAO report said.

The IRS said it welcomed the report from Collins, who started her role earlier this year.

“In response to COVID-19, the IRS delivered stimulus payments in record time,” the IRS said.

Millions of Americans started getting stimulus money within two weeks of after the CARES Act’s passage in late March. “By comparison, for the last stimulus payments in 2008, the first 800,000 payments did not start reaching taxpayers for 75 days. Our extraordinary efforts to timely implement relief in the wake of COVID-19 have taken place in the middle of an unprecedented extended filing season.”

The National Taxpayer Advocate report offered other insights on the scale of the stimulus-check distribution.

Approximately 23 million people submitted direct deposit information to get their checks quicker while 3.7 million people used the IRS’s “non-filer” too. The online portal gave the IRS information it needed to send stimulus payments to people who didn’t have an income tax filing requirement.

The Dow Jones Industrial Index DJIA, +2.32% and the S&P 500 SPX, +1.46% ended higher Monday, recovering lost ground after last week’s losses that were due to reports of a surge of coronavirus in U.S. states that have loosened restrictions.

The COVID-19 pandemic, which was first identified in Wuhan, China in December, had infected 10,199,798 people globally and 2,534,981 in the U.S. as of Monday. It had claimed at least 502,947 lives worldwide, 125,928 of which were in the U.S., according to Johns Hopkins University’s Center for Systems Science and Engineering.
