Laststatus Method POST

The LASTSTATUS method allows a company to check on their past consent and request calls to see if a taxpayer's data is waiting on the IRS to release it, available in the TaxStatus system, or has been rejected by the IRS. If rejected, this typically means there was a problem with the information provided. The most common error is an incorrect address (muat be the address of the taxpayer on their last tax filing), or the name is mispelled. You must contact the taxpayer and have them review all the fields for correctness and resend the consent or request.
