The Internal Revenue Service and the Treasury Department to date have already disbursed nearly $390 billion worth of coronavirus stimulus checks to financially hurt Americans.

But it appears that every week over the past couple of months, there have been dozens of reports of struggling Americans saying that they haven’t been paid by the U.S. government—not even from the first two rounds of stimulus.

Despite this unfortunate situation, know that there are indeed options available to claim that missing money. The IRS, for several weeks now, has continued to remind taxpayers that for this particular tax season, a handy Recovery Rebate Credit has been added to all returns.

“If you didn’t get any payments or got less than the full amounts, you may qualify for the Recovery Rebate Credit and must file a 2020 tax return to claim the credit even if you don’t normally file,” the IRS website says.

With Tax Day extended to May 17, the IRS is pressing all taxpayers to file by that date if they want to claim the missing funds.

Do take note, though, that if the deadline is still too soon, individuals can still claim the money by filing by the October 15 tax filing extension deadline. If one chooses this route, be aware that taxpayers are still responsible for interest and penalties that could continue to accrue on any tax owed.

As for the missing current round of $1,400 stimulus checks, the impacted individuals should request an IRS payment trace. Keep in mind that a similar action can be taken if the IRS “Get My Payment” tool shows that the payments have been transferred but the balance has not changed in the recipient’s bank account.

Another option for individuals is to actually speak to a live human regarding their missing stimulus checks.

The IRS Economic Impact Payment phone number is 800-919-9835—but be warned that “IRS live phone assistance is extremely limited at this time,” says the agency’s website.

What this likely means is those inquiring individuals should be prepared to sit on hold for a considerable amount of time.

It would also be a good idea to check to see if one qualifies for the new stimulus, as the IRS has reminded all U.S. taxpayers that the income levels in this third round have changed. The agency added that some individuals won’t be eligible for this payment even if they received a first or second stimulus check without any issues.

According to the details of the American Rescue Plan, individuals who earn as much as $75,000 in adjusted gross income, or couples making $150,000, qualify for the full $1,400 per person. But an individual with an income of $80,000, or a couple with $160,000, will receive nothing.
