Notice 2026-19

This notice provides guidance on the corporate bond monthly yield curve, the corresponding spot segment rates used under § 417(e)(3), and the 24-month average segment rates under § 430(h)(2) of the Internal Revenue Code. In addition, this notice provides guidance as to the interest rate on 30-year Treasury securities under § 417(e)(3)(A)(ii)(II) as in effect for plan years beginning before 2008 and the 30-year Treasury weighted average rate under § 431(c)(6)(E)(ii)(I).

YIELD CURVE AND SEGMENT RATES

Section 430 specifies the minimum funding requirements that apply to single-employer plans (except for CSEC plans

under § 414(y)) pursuant to § 412. Section 430(h)(2) specifies the interest rates that must be used to determine a plan’s target normal cost and funding target. Under this provision, present value is generally determined using three 24-month average interest rates (“segment rates”), each of which applies to cash flows during specified periods. To the extent provided under § 430(h) (2)(C)(iv), these segment rates are adjusted by the applicable percentage of the 25-year average segment rates for the period ending September 30 of the year preceding the calendar year in which the plan year begins. ¹ However, an election may be made under § 430(h)(2)(D)(ii) to use the monthly yield curve in place of the segment rates.

Section 1.430(h)(2)-1(d) provides rules for determining the monthly corporate bond yield curve, and § 1.430(h) (2)-1(c) provides rules for determining the 24-month average corporate bond segment rates used to compute the target normal cost and the funding target. Consistent with the methodology specified in § 1.430(h)(2)-1(d), the monthly corporate bond yield curve derived from February 2026 data is in Table 2026-2 at the end

of this notice. The spot first, second, and third segment rates for the month of February 2026 are, respectively, 3.96, 5.15, and 6.11.

The 24-month average segment rates determined under § 430(h)(2)(C)(i) through (iii) must be adjusted pursuant to § 430(h)(2)(C)(iv) to be within the applicable minimum and maximum percentages of the corresponding 25-year average segment rates. Those percentages are 95% and 105% for plan years beginning in 2025 and 2026. For this purpose, any 25-year average segment rate that is less than 5% is deemed to be 5%. The 25-year average segment rates for plan years beginning in 2025 and 2026 were published in Notice 2024-67, 2024-41 I.R.B. 726 and Notice 2025-47, 2025-40 I.R.B. 441, respectively.

24-MONTH AVERAGE CORPORATE BOND SEGMENT RATES

The three 24-month average corporate bond segment rates applicable for March 2026 without adjustment for the 25-year average segment rate limits are as follows:

24-Month Average Segment Rates Without 25-Year Average Adjustment Applicable Month First Segment Second Segment Third Segment March 2026 4.50 5.26 5.81

The adjusted 24-month average segment rates set forth in the chart below reflect § 430(h)(2)(C)(iv) of the Code. The

24-month averages applicable for March 2026, adjusted to be within the applicable minimum and maximum percentages of

the corresponding 25-year average segment rates in accordance with § 430(h)(2) (C)(iv), are as follows:

Adjusted 24-Month Average Segment Rates For Plan Years

Beginning In Applicable Month First Segment Second Segment Third Segment

2025 March 2026 4.75 5.26 5.81

2026 March 2026 4.75 5.25 5.81

30-YEAR TREASURY SECURITIES INTEREST RATES

Section 431 specifies the minimum funding requirements that apply to mul

tiemployer plans pursuant to § 412. Section 431(c)(6)(B) specifies a minimum amount for the full-funding limitation described in § 431(c)(6)(A), based on the plan’s current liability. Section 431(c)

(6)(E)(ii)(I) provides that the interest rate used to calculate current liability for this purpose must be no more than 5 percent above and no more than 10 percent below the weighted average of the rates

1 Pursuant to § 433(h)(3)(A), the third segment rate determined under § 430(h)(2)(C) is used to determine the current liability of a CSEC plan (which is used to calculate the minimum amount of the full funding limitation under § 433(c)(7)(C)).

Bulletin No. 2026–15 797 April 6, 2026

of interest on 30-year Treasury securities during the four-year period ending on the last day before the beginning of the plan year. Notice 88-73, 1988-2 C.B. 383, provides guidelines for determining the weighted average interest rate. The rate of interest on 30-year Treasury securities

for February 2026 is 4.76 percent. The Service determined this rate as the average of the daily determinations of yield on the 30-year Treasury bond maturing in November 2055 determined each day through February 11, 2026 and the yield on the 30-year Treasury bond maturing in

February 2056 determined each day for the balance of the month. For plan years beginning in March 2026, the weighted average of the rates of interest on 30-year Treasury securities and the permissible range of rates used to calculate current liability are as follows:

Treasury Weighted Average Rates For Plan Years Beginning In 30-Year Treasury Weighted Average Permissible Range 90% to 105%

March 2026 4.43 3.99 to 4.65

MINIMUM PRESENT VALUE SEGMENT RATES

In general, the applicable interest rates

under § 417(e)(3)(D) are segment rates computed without regard to a 24-month average. Section 1.417(e)-1(d)(3) provides guidelines for determining the min

imum present value segment rates. Pursuant to that section, the minimum present value segment rates determined for February 2026 are as follows:

Minimum Present Value Segment Rates Month First Segment Second Segment Third Segment February 2026 3.96 5.15 6.11

acquired, the latest date on which units of the same digital asset were acquired, or the highest basis—§ 1.1012-1(j)(3)(ii) treats such method as a standing order or instruction.

For units held in the custody of a broker for which the taxpayer does not make an adequate identification of the units sold, disposed of, or transferred in accordance with § 1.1012-1(j)(3)(ii), § 1.1012-1(j)(3)(i) treats such units as sold, disposed of, or transferred in order of time from the earliest date on which units of that same digital asset held in the custody of the broker were acquired by the taxpayer (“FIFO rule”). Regardless of whether the taxpayer makes an adequate identification, in the case of digital assets exchanged for different digital assets, § 1.1012-1(j)(3)(iii) deems any units withheld, either for the broker’s backup withholding obligations under section 3406, or for payment of services described in § 1.1001-7(b)(1)(ii) (digital asset transaction costs), as coming from the units received in the exchange.

Separate ordering rules, found in § 1.1012-1(j)(1) and (2), prescribe how units not held in the custody of a broker are identified as the units sold, disposed of, or transferred. Section 1.1012-1(j)(6) provides that § 1.1012-1(j) applies to all acquisitions and dispositions of digital assets on or after January 1, 2025.

Contemporaneously with the issuance of § 1.1012-1(j), the IRS issued Rev. Proc. 2024-28, 2024-31 I.R.B. 326 (July 29, 2024), which provides guidance to taxpayers regarding how to transition from a universal or multi-wallet basis allocation methodology to a wallet-by-wallet or account-by-account basis allocation methodology. Specifically, subject to certain requirements, Rev. Proc. 2024-28 provides a safe harbor for taxpayers to allocate their units of unattached basis in digital assets acquired before January 1, 2025, to a digital asset wallet or account that holds the same number of remaining digital asset units based on the taxpayer’s records of such unattached basis and remaining units so long as the alloca
