Retirement Contributions: The Employer Match, Roth vs. Traditional, and Limits

The Employer Match Is the Highest Return in Personal Finance

If your employer offers a 401(k) match, contributing enough to capture all of it is the closest thing to free money in personal finance. A common structure is '100% of the first 3%, then 50% of the next 2%' — meaning if you contribute 5% of salary, the employer adds 4%. On a $70,000 salary, that is $2,800 of your money plus $2,800 of theirs, an instant 100% return on the matched portion before any market growth.

Leaving the match on the table is the single most common and costly retirement mistake I see. Someone earning $70,000 who contributes 0% instead of 5% forgoes roughly $2,800 every year — over a career, with growth, that is hundreds of thousands of dollars abandoned. Whatever else your budget allows, contributing at least up to the full match should be the non-negotiable floor.

Roth vs. Traditional: Paying Tax Now or Later

The core choice inside most plans is Roth versus traditional, and it comes down to when you pay tax. Traditional contributions are pre-tax: they lower your taxable income today, grow tax-deferred, and are taxed as ordinary income when you withdraw in retirement. Roth contributions are made with after-tax dollars: no deduction now, but qualified withdrawals — including all the growth — are completely tax-free.

The decision hinges on whether your tax rate is higher now or expected to be higher in retirement. Early-career workers in a low bracket often favor Roth, locking in today's low rate. High earners in peak years often prefer traditional to reduce current taxable income. Many people split contributions to hedge, and it's worth noting that employer matching dollars are always traditional (pre-tax) even if your own contributions are Roth.

Contribution Limits and Catch-Up Rules

The IRS caps annual contributions, and the limits differ by account type. For 2024, the 401(k)/403(b) employee deferral limit is $23,000, with an additional $7,500 catch-up for those 50 and older. IRA contributions (Roth or traditional) are capped separately at $7,000, plus a $1,000 catch-up. These limits are indexed and typically rise each year.

• The 401(k) employee limit applies to your contributions only; employer match does not count against it (a separate, higher overall cap does).
• Roth IRA eligibility phases out at higher incomes — high earners may need a 'backdoor' Roth contribution.
• HSAs, while a health account, double as a stealth retirement vehicle with their own limits.
• Exceeding a limit triggers penalties, so coordinate contributions if you change jobs mid-year and had a 401(k) at each.

Vesting: When the Match Is Actually Yours

Your own contributions are always 100% yours immediately. Employer matching dollars, however, are often subject to a vesting schedule — a period you must stay employed before the match fully belongs to you. Two common structures are cliff vesting (0% until a set date, then 100% at once, e.g., three years) and graded vesting (a rising percentage each year, e.g., 20% per year over five).

This matters enormously when weighing a job change. Leaving two months before a three-year cliff can forfeit years of employer contributions. Before resigning, check your vesting schedule and, if the number is meaningful, factor a short delay or a signing bonus from the new employer into the decision.

The Efficient Order of Operations

With limited dollars, sequence beats intensity. A widely endorsed order for most workers is: first contribute enough to capture the full employer match; next pay down high-interest debt; then max an HSA if you have a high-deductible health plan; then contribute to a Roth or traditional IRA; and finally return to max out the 401(k) up to the annual limit.

Job Changes, Rollovers, and Not Cashing Out

When you leave a job, your 401(k) doesn't disappear, but your choices matter. You can generally leave it in the old plan, roll it into your new employer's plan, or roll it into an IRA — all without tax consequences if done as a direct rollover. What you should almost never do is cash it out: an early withdrawal before 59½ typically triggers income tax plus a 10% penalty, and it permanently erases decades of potential growth.

Rolling old accounts into a single IRA or current plan also reduces the very common problem of forgotten, orphaned 401(k)s scattered across former employers. Consolidation makes fees, allocation, and beneficiaries far easier to manage over a career.
