This bill amends the Internal Revenue Code of 1986 to introduce significant flexibility for retirement savers. It specifically allows participants aged 50 or older to elect a direct in-service rollover of employer contributions from their 401(k) plans into an individual retirement annuity, bypassing previous restrictions that typically required a separation from service for such transfers. Furthermore, the legislation establishes a safe harbor for the written explanations provided to taxpayers regarding eligible rollover distributions. This safe harbor mandates that the explanation include specific, concise, and plain language information, such as the 30-day review period, tax consequences of direct versus indirect distributions, and details on non-eligible distributions and withholding rules. The Secretary is authorized to issue regulations to update this list, with these amendments applying to taxable years beginning after December 31, 2025, to enhance clarity and flexibility in retirement planning.
