      • Address(es) on 4506C is not the Wage information Address(es) for the Years and Product being Ordered
      • 1040 and W2/1099 can have different address(s).
      • The Address does not match exactly how it appears on the Tax Returns for each year Ordered.
      • Even if the 4506C reflects the Tax Return address(s), the address needs to be what the IRS has on file for the Taxpayers IRS Master Account.
      • The Current Address on Line 3 needs to be the most recent year being ordered. Not the most Current Address the Taxpayer has lived.
      • The Previous Address on Line 4 needs to the other Address for other years ordered, if it is different than Line 3.
      • Only one Address per line. If a Taxpayer has different Addresses for all the years being ordered, a separate 4506C may need to be created with a second order.
      • Legibility is also key. If the IRS cannot read the Information, the 4506C will be Rejected by the IRS.
