Applicable Federal Rates for December 2018

Every rate the IRS published for December 2018 in Rev. Rul. 2018-30: the short-, mid- and long-term AFR at four compounding periods, the multiples, the adjusted AFR, and the § 7520 rate. The 120% mid-term row is worked below the table.

In December 2018 the mid-term AFR was 3.07% and 120% of it was 3.69% (annual compounding), so a 72(t)/SEPP payment beginning in either of the two following months could use up to the greater of 5% and 3.69%. The § 7520 rate for the month was 3.6%.

Source: IRS Rev. Rul. 2018-30, Tables 1, 2, 3 and 5 (PDF on irs.gov). Percentages are shown as the ruling prints them; nothing here is rounded or derived except the worked lines below, which are labelled as such. Rates apply to the calendar month named, under IRC § 1274(d); which month governs a given instrument depends on the Code section that uses it.

How the 120% mid-term rate is derived

The IRS applies each multiple to the semiannual mid-term AFR, then converts that semiannual rate to the other compounding periods. Multiplying the annual figure by 1.2 does not reproduce the published table; this does, within 0.01 percentage points, in every ruling since January 2000.

semiannual mid-term AFR 3.05% × 1.2 3.66% (published semiannual 120%: 3.66%) annual (1 + s/2)² − 1 3.69% (published: 3.69%) quarterly 4 × ((1 + s/2)^(1/2) − 1) 3.64% (published: 3.64%) monthly 12 × ((1 + s/2)^(1/6) − 1) 3.63% (published: 3.63%)

The § 7520 rate is the annual 120% mid-term figure rounded to the nearest 0.2%, with a tie rounding up: 3.69% → 3.6%, which is what the ruling publishes.

What these rates are for

IRC § 1274(d) requires the IRS to publish the applicable federal rates every month: the short-term rate for instruments of three years or less, the mid-term rate for over three and up to nine years, and the long-term rate beyond that, each set from the average market yield on outstanding U.S. Treasury obligations of comparable maturity. The multiples serve other Code sections: 120% of the mid-term rate caps a 72(t)/SEPP fixed-amortization or annuitization payment (Notice 2022-6) and, rounded to 0.2%, is the § 7520 rate used to value annuities, life estates and remainders; the 110%, 130%, 150% and 175% rows feed § 42, § 382, § 467 and § 468 computations. The adjusted AFR in Table 2 is the § 1288 rate for tax-exempt obligations.
