Mutual life insurance companies; differential earnings rate. The differential earnings rate for 2004 is determined for use by mutual life insurance companies to compute their income tax liability for 2004.

This revenue ruling contains a determination under § 809 of the Internal Revenue Code of the “differential earnings rate” for 2004. This rate is used by mutual life insurance companies to calculate their federal income tax liability for taxable years beginning in 2004. Notice 2005-18, 2005-9 I.R.B. 634, contained a tentative determination of this rate.

The Job Creation and Worker Assistance Act of 2002, Pub. L. 107-147, § 611, amended § 809 by adding new paragraph (j). Section § 809(j) provides that the differential earnings rate shall be treated as zero for purposes of computing both the differential earnings amount and the recomputed differential earnings amount for a mutual life insurance company’s taxable years beginning in 2001, 2002, or 2003. See Notice 2002-33, 2002-1 C.B. 989. Under § 809(j), the final recomputed differential earnings rate for 2003 is zero. Subsequently, the Pension Funding Equity Act of 2004, Pub. L. 108-218, § 205, repealed § 809 of the Code for taxable years beginning after December 31, 2004. Therefore, the Internal Revenue Service is required to determine a differential earnings rate for 2004.

The final determination of the rates is set forth in Table 1.
