Stimulus verify for lower than anticipated? The I.R.S. says some delays are tied to spousal money owed.

More than 90 million taxpayers have already received a total of $ 240 billion in stimulus payments – but not all have yet received the full amount they can get.

The Internal Revenue Service has an explanation for at least some of them.

Married individuals who filed their tax returns together can receive their incentives in two separate installments if their tax return includes what is known as a spouse’s injured claim, which a taxpayer can claim if part of their tax refund is withheld on a spouse’s overdue debts, e.g. as federal or state taxes, child benefits or student loans.

In most cases, according to the IRS on Tuesday, the second part of the payment will be delivered as you stated it on your tax return – although it is possible that one part will be delivered by direct deposit and the other by mail. The second part could be delayed by a few weeks, according to the agency.

Another set of economic payments will be issued on Wednesday that may solve the problem for some couples. But for those still wondering when the relief payment might arrive, the IRS suggested that both taxpayers use the Get My Payment tool on return to check payment status using their own social security numbers.

It is unclear how many taxpayers are affected or if there are other issues that are also causing delays. But nearly 7,000 people have found their way to a Facebook group called Half Stimulus Missing / Received Status to trade in frustrations and information.

Many other Americans – including some who have received Social Security – are still waiting.

Those in charge of the House Ways and Means Committee sent a letter to the Internal Revenue Service and the Social Security Administration Monday about late payments to those who do not need to file tax returns and who are receiving benefits from Social Security, Additional Security Income, and Railroad Retirement Board and Veterans Affairs. The IRS, the letter said, was unable to provide an expected schedule.

“Some of our most vulnerable seniors and people with disabilities, including veterans who have served our country with honor, cannot pay for basic needs while awaiting their overdue payments,” the legislature wrote.

An IRS spokesman confirmed that the agency does not yet have a deadline for these payments to arrive. Those who filed a tax return in the past year or who registered with the agency’s nonfilers tool for past stimulus payments shouldn’t be affected.
