IRS Form 4506-C & 4506-T
MISMO’s new dataset supplies a standard set of data points that map to Form 4506-C, which is used for requesting tax transcripts from the IRS. The new dataset, accompanied by a sample XML file as well as a numbered form, shows the necessary structure for implementing the dataset using the MISMO v3.5 reference model. Together, this information package will supply lenders and vendors a MISMO-standard method for completing IRS Form 4506-C, which fully replaced the Request for Transcript of Tax Return (IRS Form 4506-T), on May 1, 2021.
The IRS Form 4506-C was approved as Candidate Recommendation status in June of 2022.
In addition to the dataset for IRS Form 4506-C, MISMO created a dataset for the previously used IRS Form 4506-T. This dataset provides historical context of the different MISMO data points needed for the new form.
A related initiative is MISMO's Taxpayer Consent Language which provides a consistent way for
the mortgage industry to obtain borrower consent to share tax information received from the IRS with other parties involved in a mortgage transaction.
