Traditional 401k deferrals save federal and generally Missouri tax now at rates up to about 4.8% at the top bracket. Roth 401k trades that upfront savings for potential federally tax-free qualified withdrawals. Typical 3–6% employer matches are often traditional dollars. Many workers capture the full match first, then split additional savings based on expected retirement tax rates.
The IRS limit for employee 401k deferrals is $24,500 in 2026. Workers aged 50 and older may contribute an additional $8,000 catch-up for $32,500 total. Optional higher catch-ups may apply at ages 60–63 under federal rules. Combined employee and employer contributions can reach up to $72,000 in 2026 (plus catch-ups where allowed).

Traditional 401k lowers federal and generally Missouri taxable income now. Roth 401k uses after-tax dollars but can provide federally tax-free qualified withdrawals; confirm Missouri treatment of Roth distributions with a tax advisor.
Total contributions from you and your employer generally cannot exceed $72,000 in 2026 (plus allowed catch-ups). Employer matching dollars count toward that cap.
Many employers offer Roth 401k. After-tax contributions can grow federally tax-free if qualified; weigh current Missouri tax on Roth deferrals against your expected retirement tax picture.
