Catch-up contributions for certain participants must be made on a Roth basis
See updates to Roth catch-up contributions here.
Under current law, catch-up contributions can be either made on a pre-tax or Roth basis. Going forward, all catch-up contributions must be made on a Roth basis for employees with compensation in excess of $145,000 the prior year (indexed annually), regardless of whether or not “regular” contributions are made on a pre-tax basis.
