Understanding 401(k) contribution limits, employer matching, Roth vs traditional options, and catch-up provisions can help you build a stronger retirement savings strategy.

1 / 7

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

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

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Roth contributions are made after-tax but grow and are withdrawn tax-free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

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
