This notice provides transition relief from the “once-in-always-in” (OIAI) exclusion condition for excluding part-time employees under § 1.403(b)–5(b)(4)(iii)(B) of the Treasury Regulations. Under the OIAI exclusion condition, for a § 403(b) plan that excludes part-time employees from making elective deferrals, once an employee is eligible to make elective deferrals, the employee may not be excluded from making elective deferrals in any later exclusion year on the basis that the employee is a part-time employee. In addition, in applying the OIAI exclusion condition for exclusion years after the transition relief ends, this notice provides a fresh-start opportunity for plans.

Section 83 generally provides for the federal tax treatment of property transferred in connection with the performance of services. Section 83(i) allows certain employees to elect to defer income that would otherwise be included under § 83(a) upon the exercise of a stock option or settlement of a stock-settled restricted stock unit. Income subject to such an election may be deferred for up to 5 years, subject to certain limitations. The notice provides guidance to taxpayers on (1) application of the requirement in § 83(i)(2)(C)(i)(II) that grants be made to 80% of the employer’s employees, (2) application of income tax withholding to the deferred income related to qualified stock, and (3) the manner in which an employer may opt out of permitting employees to elect the deferred tax treatment even if the requirements under § 83(i) are otherwise met.

This notice provides interim guidance for taxpayers to determine the amount of parking expenses for qualified transportation fringes (QTFs) that is nondeductible under § 274(a)(4) of the Internal Revenue Code (Code) and for tax-exempt organizations to determine the corresponding increase in the amount of unrelated business taxable income (UBTI) under § 512(a)(7) attributable to the nondeductible parking expenses. Sections 274 and 512 were amended by the Tax Cuts and Jobs Act, Pub. L. No. 115–97, §§ 13304 and 13703, 131 Stat. 2054, 2123, 2169 (2017) (the Act), effective for amounts paid or incurred after December 31, 2017. As amended by the Act, § 274(a)(4) generally disallows a deduction for expenses with respect to QTFs provided by taxpayers to their employees, and § 512(a)(7) generally provides that a tax-exempt organization’s UBTI is increased by the amount of the QTF expense that is nondeductible under § 274. However, the Act does not address how to determine the amount of the QTF expense that is nondeductible or treated as an increase in UBTI.
