Create a Section 603 high earner status for an employee for a specific year.
Section 603 of the SECURE 2.0 Act applies to employees aged 50 or older whose prior-year FICA wages exceed the IRS threshold. These employees are classified as high earners, and their catch-up contributions to pre-tax retirement benefits must be designated as post-tax contributions.
