401(k) Contribution Limits
- 2025 employee deferral limit: $23,500, adjusted annually for inflation
- Total limit (employee + employer): $70,000 in 2025, includes all sources
- These limits apply across all 401(k) accounts if you have multiple employers
- Exceeding limits triggers penalties, excess deferrals must be corrected by April 15
Employer Match and Vesting
- A common match formula is 50% of contributions up to 6% of salary
- Not contributing enough to get the full match is forgoing compensation
- Vesting schedules determine when matched funds are fully yours, check your plan
- Some plans match per paycheck, so front-loading contributions can cost you match dollars
Traditional vs Roth 401(k)
- Traditional contributions reduce taxable income now but are taxed on withdrawal
- Roth contributions are made after-tax but grow and are withdrawn tax-free
- If you expect higher tax rates in retirement, Roth may be more advantageous
- Splitting between both can provide tax diversification and flexibility later
Catch-Up Contributions and Super Catch-Up
- Workers age 50 and older can contribute an additional $7,500 per year
- SECURE 2.0 super catch-up: up to $11,250 for ages 60 to 63, effective 2025
- High earners ($145,000+ in prior-year wages) must make catch-ups as Roth under SECURE 2.0
- At age 64 you revert to the regular catch-up amount, the window is limited
After-Tax Contributions and Mega Backdoor Roth
- Some plans allow after-tax contributions beyond the employee deferral limit
- After-tax funds can convert to Roth via in-plan conversion or rollover to a Roth IRA
- This mega backdoor Roth strategy can shelter up to $46,000+ more per year
- Not all plans permit this, check for after-tax contributions and in-service withdrawals
Common 401(k) Mistakes to Avoid
- Cashing out when changing jobs triggers taxes plus a 10% penalty if under 59 and a half
- Defaulting into overly conservative funds when decades from retirement hurts growth
- Ignoring asset allocation, target-date funds are one option but may not suit everyone
- Not reviewing fees, high expense ratio funds erode returns significantly over time
Prioritization: 401(k) vs IRA vs HSA
- Generally, contribute enough to get the full employer match first
- HSAs offer triple tax benefits and can serve as a supplemental retirement account
- IRAs provide more investment choices but have lower limits ($7,000 in 2025)
- Auto-escalation increases your deferral rate 1 to 2% annually until a cap is reached
- After maximizing match and HSA, consider maxing 401(k) before taxable accounts
