SECTION 9. NOLS AND UBTI
Internal Revenue Bulletin 2018-36 · 2026-10-03 edition · updated 2026-10-04 · United States
Prior to the Act, § 172 allowed an NOL deduction equal to the sum of NOLs permitted to be carried back to the taxable year from succeeding taxable years and the NOLs permitted to be carried forward from preceding taxable years. An NOL generally could be carried back two years and carried forward twenty years. See § 172(b) (prior to the Act). Section 512(b)(6), which was not changed by the Act, generally permits exempt organizations subject to the unrelated business income tax under § 511, including exempt organizations with more than one unrelated trade or business, to take the NOL deduction provided in § 172. In particular, § 512(b)(6)(A) states that the NOL for any taxable year, the amount of the NOL carryback or carryover to any taxable year, and the NOL deduction for any taxable year shall be determined under § 172 without taking into account any amount of income or deduction that is excluded under § 512(b) in computing UBTI. For example, a loss attributable to an unrelated trade or business is not to be reduced by reason of the receipt of dividend income. See § 1.512(b)–1(e)(1). An NOL carryover is allowed only from a taxable year for which the taxpayer is subject to the provisions of § 511, or a corre
5However, VEBAs and SUBs are taxed on income to the extent that the amount of assets in the VEBA or SUB at the close of the taxable year exceed the account limit described in § 512(a)(3)(E) and § 1.512(a)–5T. See also Prop. Reg. § 1.512(a)–5.

sponding provision of prior law. See § 512(b)(6)(B); § 1.512(b)–1(e)(3).
However, § 512(a)(6) changes how an exempt organization with more than one unrelated trade or business calculates and takes NOLs into account with respect to a particular trade or business. In particular, § 512(a)(6)(A) requires such an organization to calculate UBTI, including for purposes of determining any NOL deduction, separately with respect to each trade or business for taxable years beginning after December 31, 2017 (post-2017 NOLs). The Congressional intent behind this change is to allow an NOL deduction “only with respect to a trade or business from which the loss arose.” H.R. Rep. No. 115–466, at 547–48. In the first taxable year beginning after December 31, 2017, no exempt organization with more than one unrelated trade or business will have an NOL deduction to take against the UBTI of a particular trade or business calculated under § 512(a)(6)(A).
Additionally, in order to preserve NOLs from tax years prior to the effective date of the Act, Congress created a special transition rule to permit the carryover of any NOL arising in a taxable year beginning before January 1, 2018 (pre-2018 NOLs). In particular, section 13702(b)(2) of the Act provides that § 512(a)(6)(A) does not apply to pre-2018 NOLs; rather, pre-2018 NOLs are taken against total UBTI calculated under § 512(a)(6)(B). Accordingly, even though an exempt organization with more than one unrelated trade or business will not have any NOL deductions when calculating UBTI with respect to a separate trade or business under § 512(a)(6)(A) for the first taxable year beginning after December 31, 2017, such an organization may be able to take an NOL deduction against total UBTI calculated for such year under § 512(a)(6)(B) if the organization has pre-2018 NOLs.
In the second taxable year beginning after December 31, 2017, an exempt organization with more than one unrelated trade or business may have both pre-2018 NOLs and post-2017 NOLs. Section 512(a)(6) may have changed the order in which an organization would ordinarily take losses because § 512(a)(6)(A) requires an organization with more than one unrelated trade or business to calculate UBTI separately (including for purposes of
determining any NOL deduction) with respect to each such trade or business before calculating total UBTI under § 512(a) (6)(B). If § 512(a)(6) is read as an ordering rule for purposes of calculating and taking the NOL deduction, post-2017 NOLs will be calculated and taken before pre-2018 NOLs because the UBTI with respect to each separate trade or business is calculated under § 512(a)(6)(A) before calculating total UBTI under § 512(a)(6)(B).
Furthermore, section 13302 of the Act made extensive changes to § 172, including limiting post-2017 NOLs to the lesser of (1) the aggregate NOL carryovers to such year, plus the NOL carrybacks to such year, or (2) 80 percent of taxable income computed without regard to the deduction generally allowable under § 172. The limitation in § 172(a) applies only to post-2017 NOLs, but a question exists regarding how the § 172(a) 80 percent income limitation applies when both pre-2018 and post-2017 NOLs exist. The Treasury Department and the IRS intend to issue guidance regarding how § 172 generally applies. However, because § 512(a)(6) provides a more specific rule than the one found in § 172 regarding how the NOL deduction is calculated and taken in the context of calculating UBTI, the Treasury Department and the IRS are requesting comments regarding how the NOL deduction should be taken under § 512(a)(6) by exempt organizations with more than one unrelated trade or business and, in particular, by such organizations with both pre-2018 and post-2017 NOLs. The Treasury Department and the IRS also request comments on the ordering of pre-2018 and post-2017 NOLs and the potential treatment of pre-2018 NOLs that may expire in a given tax year if not taken before post-2017 NOLs.
