A shade below one hundred sixty million coronavirus stimulus checks worth $376 billion have been disbursed to struggling Americans over the past month.

However, some of those reportedly included in these current payments were headed to the bank accounts of deceased individuals. In such an unfortunate situation, the Internal Revenue Service has put out a notice that spouses or relatives will need to make time to return the funds to the agency.

Be aware, though, that this impacts only U.S. taxpayers who died before January 1, 2021, and know that the extra $1,400 per dependent is also not available for a parent who died before that date.

There is, however, one exception to the rule. The IRS has stated that if the person who died is a married member of the U.S. military, the surviving spouse is still eligible for the $1,400 stimulus payment.

But these individuals will still need to meet the income thresholds as outlined by the IRS. Those who earn as much as $75,000 in adjusted gross income (AGI), or couples making $150,000—in addition to their children or adult dependents—qualify for the full $1,400 per individual.

Moreover, single parents with at least one dependent who earn $112,500 or less also get the full amount.

One other group of people that needs to return the stimulus checks are nonresident aliens. According to the IRS, in most cases, they are not considered U.S. citizens, don’t possess a green card, and often are not physically present in the United States for the required amount of time.

But keep in mind that a lawful permanent resident with a valid Social Security number who pays taxes in the United States is entitled to the stimulus funds, as these individuals are legally residing permanently in the country and are generally given an alien registration card, also known as a green card.

It is certainly possible to be a qualifying resident alien without possessing a green card. This includes people who are physically present in the United States on at least thirty-one days during the current year, one hundred eighty-three days in the past three years, including the current year, and possess a valid Social Security number, according to the IRS.

They also cannot be claimed as a dependent by another taxpaying individual.

This current fifth batch of payments includes 1.2 million direct deposit payments and nearly eight hundred thousand paper checks. The recent batches also have “plus-up” or supplemental payments for those who only received partial $1,400 payments on an earlier date.

The newest figures represent 84 percent of the $450 billion total earmarked for stimulus funds, the IRS noted.
