March 2015 Update: Adjusted AFRs

In the March 2, 2015 Federal Register the IRS and Treasury published proposed regulations making good on their intention announced in Notice 2013-4, discussed below, to change the way in which they calculate the adjusted applicable federal rates. See Proposed Change to the Adjusted Applicable Federal Rates for more informantion.

Special Note: March 2013 Adjusted AFRs

In Notice 2013-4, the IRS announced that it was considering changes in the way it determines the adjusted AFRs and adjusted federal long-term rate published in Tables 2 and 3, respectively, of its monthly AFR revenue ruling. The IRS also announced interim guidance (essentially constraining the adjusted AFR so that it would never be higher than the comparable AFR) that it said would be reflected in its March 2013 AFR ruling. However, the version of that March 2013 AFR ruling originally released by the IRS did not reflect the changes of the interim guidance. The IRS has corrected the March 2013 AFR ruling and it and the corrected rates are available at this site.

Each month, the U.S. Internal Revenue Service publishes base interest rates known as the applicable federal rates ("AFRs"). These interest rates are used for various purposes under the Internal Revenue Code, particularly the imputed interest and original issue discount rules. The AFRs for a particular month are generally made available during the third or fourth week of the preceeding month; the current rate information presented will ordinarily contain the four (4) most recent available months since, in certain circumstances, the AFR to be utilized is determined as the lowest relevant AFR for the month of the transaction and the two preceding months.

In addition, the highest of the adjusted federal long-term rates for the month of a "change in ownership" under Internal Revenue Code section 382 and the prior two months becomes the federal long-term tax-exempt rate for that month, which in turn determines the annual limitation on the use of corporate net operating loss carryovers following such a change in ownership.

The current IRS Revenue Ruling has all the AFRs (and rates derived from the AFRs) but only for the most recently available month ([an error occurred while processing this directive]).
