Included in Notice 2023-62PDF, the notice provides initial guidance for section 603 of the SECURE 2.0 Act, enacted in December 2022. Starting next year the new rule applies an employee who participates in a 401(k), 403(b) or governmental 457(b) plan and whose prior-year Social Security wages exceeded $145,000.
