The IRS and major software companies who prepare and file taxes for their clients have warned that some customers may face a delay in receiving stimulus checks. Although the checks have been disbursed from the end of December there have been a few hitches in the procedures.

Millions of taxpayers, who have active, direct deposit information on file with the IRS, have already started receiving deposits in their bank accounts. However, almost 14 million citizens may face problems.

Some taxpayers used a tax preparer and “Refund Transfer Services.” This allows them to pay their tax preparer out of their tax refund, making it customer friendly. This led to delayed payments due to an administrative glitch.

In April, the preparer created a temporary bank account to receive tax refunds, took its fee and then gave the tax filer the remaining amount and closed the account. The IRS used the closed bank accounts on file, leaving the funds stagnant in closed, unused accounts.

The IRS has said that the money will reach the taxpayers despite delays. A tax preparation company, H&R Block said that the IRS Get My Payment website may display an account number that the tax payer may not recognize. It added that those who opted for “Refund Transfer” may see this number.

In their statement, sent by email, to NBC News they also told tax filers not to worry and that they will get their money: by direct deposit, check or Emerald Card.

The consumer advocacy group Public Citizen said that citizens need to get food on the table and “can’t afford to wade through bureaucracy or wait for a paper check.”
