Deemed-Issuance Ratio

Deemed-Issuance Ratio for Internal Revenue Code (IRC) 817(h)

The Federal Housing Finance Agency (FHFA) announced the first deemed-issuance ratio (for the 2019 calendar year) in accordance with Internal Revenue Service (IRS) guidelines on the trading of the Uniform Mortgage-Backed Security on December 6, 2018.  IRS Revenue Procedure 2018-54 calls for FHFA to determine a deemed-issuance ratio for each calendar year based on the ratio of TBA-eligible securities issued by Fannie Mae and Freddie Mac during the 24-month period ending October 31 of the preceding year.

On December 3, 2024, FHFA an​nounced ​the deemed-issuance ratio for the 2025 calendar year.

​The IRS procedure provides that the ratio may be rounded as long as the rounded ratio is further from 50-50 than the actual observed data. Therefore, the deemed-issuance ratio for the 2025 calendar year is 51 percent Fannie Mae and 49 percent Freddie Mac.

FHFA plans to announce the ratio annually at least three weeks prior to the affected calendar year and will update this table accordingly.
