401k Basics: What Every Saver Should Know

If you hear "401k" and think it’s just for big corporations, think again. It’s a tax‑advantaged retirement account that many employers offer, and you can use it to build a solid financial future. The plan lets you set aside part of your paycheck before taxes, which can lower your taxable income today while the money grows tax‑free until you retire.

Most companies match a portion of your contributions – that’s free money you don’t want to miss. For example, a 5% match on a 3% contribution means you’re effectively earning a 5% return on that slice of your salary instantly. The key is to contribute enough to get the full match; otherwise, you’re leaving money on the table.

How Much Can You Contribute?

The IRS sets annual limits. In 2025, the employee contribution cap is $23,000, and if you’re 50 or older, you can add a $7,500 “catch‑up” amount. These numbers can change each year, so keep an eye on the latest updates. Remember, you don’t have to max out the limit, but aiming for the match and increasing contributions gradually can boost your retirement balance significantly.

Contributions are taken directly from your paycheck, making it a painless way to save. If you’re a freelancer or self‑employed, you might consider a solo 401k, which works similarly but lets you contribute both as employee and employer, potentially doubling your savings power.

Withdrawals, Rollovers, and Penalties

When you hit 59½, you can start pulling money out without a 10% early‑withdrawal penalty. However, you’ll still owe ordinary income tax on the amounts you take. If you need cash earlier, you can explore a few options: a 401k loan, qualified hardship withdrawals, or a qualified domestic relations order (QDRO) in divorce cases. Each has rules and potential tax hits, so tread carefully.

If you change jobs, you have three main choices: leave the money where it is, roll it over to your new employer’s plan, or move it into an IRA. A direct rollover avoids withholding taxes and keeps the tax‑deferred status intact. Indirect rollovers (where the funds are sent to you first) can lead to a mandatory 20% withholding and may trigger penalties if not completed within 60 days.

Roth 401k options add another layer. Contributions are made with after‑tax dollars, but qualified withdrawals are tax‑free. This can be a smart move if you expect to be in a higher tax bracket later. Just remember the Roth 401k also follows the 59½ rule for penalty‑free withdrawals, with a five‑year holding period for earnings.

Bottom line: treat your 401k like a long‑term garden. Plant seeds early, water consistently by increasing contributions, prune wisely by avoiding early withdrawals, and reap the harvest when you retire. Keep track of contribution limits, match opportunities, and rollover rules to make the most of this powerful retirement tool.
