401(k) Benefits Explained
Tax-Deferred Growth
Your investments grow without being taxed each year. This compound growth can significantly boost your retirement savings compared to taxable accounts.
Free Money from Employer
Employer matching is an instant 50-100% return on your contribution. Not taking the full match is leaving money on the table.
Lower Your Tax Bill
Traditional 401(k) contributions reduce your taxable income now. If you're in the 22% bracket, a $10,000 contribution saves you $2,200 in federal taxes.
Frequently Asked Questions
What is the 401(k) contribution limit for 2025?
For 2025, the employee contribution limit is $23,500. If you're 50-59 or 64+, you can contribute an additional $7,500 catch-up ($31,000 total). NEW for 2025: Ages 60-63 get a 'super catch-up' of $11,250 extra ($34,750 total). The total limit including employer contributions is $70,000.
What's the difference between Traditional and Roth 401(k)?
Traditional 401(k) contributions are pre-tax, reducing your current taxable income. You pay taxes when you withdraw in retirement. Roth 401(k) contributions are after-tax, so you don't get an immediate tax break, but withdrawals in retirement are tax-free. Choose Traditional if you expect to be in a lower tax bracket in retirement.
How does employer matching work?
Many employers match a percentage of your contributions up to a limit. For example, '50% match up to 6%' means if you contribute 6% of your salary, your employer adds 3%. This is free money - always contribute enough to get the full match!
What is the new super catch-up contribution for 2025?
Starting in 2025, employees aged 60-63 can make a 'super catch-up' contribution of $11,250 (instead of the regular $7,500 catch-up). This allows a maximum contribution of $34,750 for those in this age range. This is part of the SECURE 2.0 Act changes.
Should I max out my 401(k)?
At minimum, contribute enough to get your full employer match. After that, consider maxing out if: you're in a high tax bracket (Traditional 401k saves more), you've maxed other tax-advantaged accounts (HSA, IRA), and you can afford to lock away the money until age 59½.
