The Retirement Match and Why to Take It

Why this matters

When a shop offers to match what you put into a retirement plan, the match is pay. It is part of what the shop spends on you, and the only way to collect it is to contribute yourself. A tech who contributes nothing, or contributes below the level the match goes up to, is turning down part of their compensation every week, usually without noticing, because the money never shows on the stub as missing. The second thing techs miss is vesting: the match you have been credited is not fully yours until you have been there long enough, and in a trade where people change shops every couple of years, the timing of a move can decide whether a year of match leaves with you or stays behind.

This is not personal financial or legal advice. It explains how matches and vesting work so you can read your own plan.

How a match formula reads

A match formula has two parts: the rate the shop matches at, and the cap on how much of your pay it will match. Read them together.

• "50 percent of the first 6 percent." You contribute 6 percent of pay, the shop adds 3 percent. Contribute 2 percent and the shop adds 1 percent. Contribute 10 percent and the shop still adds 3 percent, because the match stops at 6.
• "100 percent of the first 3 percent, plus 50 percent of the next 2 percent." Contribute 5 percent and the shop adds 3 plus 1, so 4 percent. This is a common safe harbor formula, a design that lets the plan skip certain IRS fairness tests in exchange for generous, fast-vesting contributions.
• A SIMPLE IRA match, used by many small shops instead of a 401(k), is typically dollar for dollar up to 3 percent of pay.

The number that matters is the contribution level that collects the whole match. In the first formula it is 6 percent; in the second it is 5. Anything below it leaves match on the table. Anything above it is still good saving, but it is no longer earning a match.

Watch the automatic default. Plans established after late 2022 generally must enroll new employees automatically starting in 2025 under the SECURE 2.0 Act, commonly at a default somewhere around 3 percent, with exceptions for small and new businesses. Being enrolled is not the same as collecting the full match. If the default is 3 percent and the match runs to 6, you are collecting half.

Your money is always yours; the match vests

Your own contributions, called elective deferrals, are always 100 percent vested under federal law (Internal Revenue Code 411). Quit tomorrow and every dollar you put in, plus its earnings, goes with you.

The match can vest over time, within limits the Code sets. For a 401(k)-type plan, the match must vest at least as fast as one of two schedules (IRC 411(a)(2)(B)):

• Three-year cliff: zero percent until you complete three years of service, then 100 percent.
• Six-year graded: 20 percent after two years, then another 20 percent each year, reaching 100 percent after six.

A plan may vest faster, and many do. Most safe harbor matches and all SIMPLE IRA contributions vest immediately; one automatic-enrollment variant of safe harbor may use a two-year cliff. Your summary plan description, the plain-language plan booklet the plan must give you, states which schedule applies, and the Department of Labor's plain-language guide to retirement plans explains what else it must tell you.

What counts as a year of service matters for seasonal techs. A plan may credit a year of vesting service only for a plan year in which you work at least 1,000 hours (IRC 411(a)(5)), or it may measure elapsed time from your hire date instead. A full-time tech clears 1,000 hours easily even with a winter layoff. A tech who started late in a plan year, or who works part of the year, may find that year does not count. The SPD tells you which method your plan uses, and your stub's year-to-date hours let you check it.

Three plan details that change what you collect

• What "pay" means for the match. The plan document defines compensation, and some definitions exclude bonuses, spiffs or commission. For a commission or flat-rate tech whose spiffs are a real share of income, a match on "base pay only" is worth less than it sounds. The SPD says which.
• Per-paycheck match versus a true-up. Many plans match each paycheck separately. If your contribution percentage changes during the year, or you hit the IRS annual contribution limit (indexed each year) before December, a per-paycheck match can quietly stop for the rest of the year. Plans with an annual true-up fix that after year end. Ask which yours does before you change your percentage mid-year.
• Roth or traditional, and where the match lands. Many plans let you choose Roth contributions, which are taxed now and come out tax-free later, instead of traditional ones, which save tax now and are taxed later. The match has traditionally gone into the pre-tax side regardless; under SECURE 2.0 a plan may now offer the match as Roth, taxed to you in the year it is made. Either way, the match rate itself does not change.

Worked example: one tech, two decisions

Every amount here is in W, the tech's weekly gross pay, so a year of pay is 52 W. The plan: match of 50 percent of the first 6 percent, six-year graded vesting measured in years with 1,000 or more hours. The tech was auto-enrolled at 3 percent two years and eight months ago and has worked well over 1,000 hours in every plan year, including the first.

Decision one: raise the contribution from 3 to 6 percent?

• At 3 percent the tech contributes 1.56 W a year (3 percent of 52 W) and the shop adds half of that, 0.78 W.
• At 6 percent the tech contributes 3.12 W a year and the shop adds 1.56 W.
• Match gained by raising: 1.56 W minus 0.78 W, or 0.78 W a year, most of a week's pay, every year.
• The cost to take-home is less than the 1.56 W of extra contribution, because traditional 401(k) contributions come out before federal and most state income tax. If this tech's combined income tax rate on the last dollar earned is about 17 percent, take-home falls by 1.56 W times 0.83, or about 1.29 W a year, to put 1.56 W of their own money plus 0.78 W of match, 2.34 W in total, into the account. Social Security and Medicare are still withheld on the contribution, so the saving is on income tax only.

Decision two: a competing shop offers more per hour, starting next month. At two years and eight months, the tech has completed two years of vesting service.

• Match credited so far, at the old 3 percent contribution: 0.78 W a year for 2.67 years, about 2.08 W, before investment growth.
• Vested at two years: 20 percent of 2.08 W, about 0.42 W. Leaving now forfeits the other 1.66 W.
• Staying four more months reaches three years and 40 percent vesting. If the tech also raises to 6 percent for those four months, the match credited for that third of a year is 1.56 W times one third, or 0.52 W, bringing the total to 2.60 W. Forty percent of 2.60 W is 1.04 W vested.
• The four months move vested match from 0.42 W to 1.04 W, a gain of 0.62 W, on top of four months' wages earned either way.

So the question for the tech is whether the new shop's higher rate, over the next four months, beats 0.62 W of vested match. A meaningful raise usually does, especially if the new shop's own match starts immediately. A small raise often does not. Either way, it is arithmetic you can do in five minutes instead of a guess.

What would change the answer. If the plan used a three-year cliff instead, vesting at two years and eight months would be zero and the four months would be worth the entire 2.60 W credited by then, a much stronger reason to wait. If the first plan year had come in under 1,000 hours, the tech would have only one year of vesting service, zero percent vested under graded vesting, and staying four months would not reach 40 percent at all. And if the match were safe harbor or SIMPLE IRA, it would already be fully vested and the timing would not matter.

Why starting early outweighs starting big

Money contributed earlier compounds longer. As an illustration only, not a forecast, assume a steady 6 percent a year after inflation. At that rate money roughly doubles every 12 years, so a contribution made at 25 has 40 years to grow to about ten times its size by 65, while the same contribution at 37 has 28 years and grows to about five times. The 25-year-old's contribution ends up roughly twice as large. Real returns vary year to year and can be negative for years at a time; the point is the ratio between starting dates, not the rate. An apprentice collecting a small match on small pay is buying the most expensive-to-replace years of growth.

When you leave the shop

Your vested balance stays yours. The options, roughly in order of how often they are the right one:

• Roll it directly into your new employer's plan or into an IRA. A direct rollover moves the money trustee to trustee with no tax. If the plan instead cuts a check to you, it must withhold 20 percent for federal income tax (IRC 3405(c)), and you have 60 days to deposit the full amount, including the withheld part from your own pocket, to avoid tax on it.
• Leave it in the old plan, if the balance is above the small-balance threshold the law sets; below it, the plan can push you out, often into an IRA it selects.
• Cash it out. The money is taxed as income, and before age 59 and a half usually carries an additional 10 percent tax (IRC 72(t)). One exception applies to employer plans if you leave the job in or after the year you turn 55. Cashing out small balances at every job change is the single most common way a tradesperson reaches 50 with nothing saved.
• An outstanding plan loan usually becomes due when you leave. If you cannot repay it, it is treated as a distribution, but a loan offset caused by leaving can generally be rolled over until your tax filing deadline for that year, extensions included.

Before you resign, check your vesting date and any loan balance. Both are on the plan's website or statement, and both can turn a well-timed move into a costly one.
