Retirement saving just got a rule change that will quietly reshape how high earners build their nest egg starting in 2026. The IRS now requires many employees who make catch-up contributions after age 50 to route those extra savings into Roth accounts instead of traditional pre-tax ones. That shift sounds small on paper, but it changes how taxes hit both now and later in retirement.
For years, catch-up contributions acted like a tax-saving bonus round at the end of a career. Workers could lower taxable income today while padding retirement accounts. The new rule flips that script for higher earners and pushes more savings into accounts that grow tax-free but do not reduce current taxable income.
