IR-2020-158, July 15, 2020 WASHINGTON — The Internal Revenue Service has started sending letters to taxpayers who have experienced a delay in the processing of their Form 7200, Advance Payment of Employer Credits Due To COVID-19PDF. A taxpayer will receive letter 6312 if the IRS either rejected Form 7200 or made a change to the requested amount of advance payment due to a computation error. The letter will explain the reason for the rejection or, if the amount is adjusted, the new payment amount will be listed on the letter. A taxpayer will receive letter 6313 if the IRS needs written verification from a taxpayer that the address listed on their Form 7200 is the current mailing address for their business. The IRS will not process Form 7200 or change the last known address until the taxpayer provides it. For more information on the employer credits, see Employer Tax Credits.
