The Internal Revenue Service has admitted that some couples are receiving their coronavirus stimulus checks under the American Rescue Plan in two separate payments.

According to the agency, the reason is apparently due to a glitch in the system that divides the payments for married couples in which one individual has filed an injured spousal claim.

However, many couples who have already received the direct deposits were initially led to believe that they received only half of the stimulus payment they were entitled to.

This led to hundreds of taxpayers expressing their frustration in the Facebook group called “Half Stimulus Missing/Received Status,” which was set up “for stimulus recipients that are seeing only half of their expected payment as pending or deposited. With little being reported to help us figure this out, we can help each other until we find an answer.”

The IRS has assured the public that the second half of the payment may arrive in the same week or within weeks of the first payment, adding that these couples can check the status of their payments using the IRS “Get My Payment” tool at www.irs.gov/coronavirus/get-my-payment.

To use it, you will just need to enter your full Social Security or tax ID number, date of birth, street address, and ZIP code. But the agency noted that each spouse’s status should be checked separately to see if the payments are indeed arriving separately.

However, be aware that some individuals will receive a message that says, “Payment Status Not Available.” “If you get this message, either we have not yet processed your payment, or you are not eligible for a payment,” the IRS says. “We will continue to send the 2021 Economic Impact Payment to eligible individuals throughout 2021.” 

Others will get a “Need More Information” message, which means that the stimulus check was returned to the IRS because the post office was unable to deliver it. If your address has recently changed, the best way to update it is to “file your 2020 tax return with your current address, if you haven’t already done so. Once we receive your current address, we will reissue your payment,” the IRS noted.

Earlier this week, the IRS and the U.S. Treasury announced that roughly a hundred million more stimulus checks—totaling more than $420 billion—are headed to financially struggling Americans through direct deposit and traditional mail over the course of the next several weeks.

If you’re still patiently waiting to receive your third stimulus check, take note that fewer Americans will receive checks this time around, so make sure to confirm if you even qualify. Individuals 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.
