The True-Up Provision: Recovering Missed Employer Match

A true-up provision is a safety net built into some 401(k) plans. If you accidentally miss your employer's full match because you maxed out your contributions early in the year, a true-up compensates you with a lump-sum match deposit later in the year. It's not common, but when it exists, it protects high earners from an expensive mistake. Understanding whether your plan has this feature could save you thousands of dollars in lost benefits.

Quick definition: A true-up provision allows your employer to deposit the match you would have received for the full year, even if you stopped contributing early after hitting the annual deferral limit.

Key takeaways

• True-up provisions are rare but valuable; only larger plans typically offer them
• They're most useful for high earners who may max out contributions before year-end
• Without a true-up, early maxouts cause you to lose months of employer match
• Not all plans have true-ups; you must check your plan document to know
• If you're in a high-income bracket, request a true-up as part of compensation negotiations

Why True-Ups Exist

The 401(k) deferral limit (currently $24,000 for 2024–2025) is an annual cap on employee contributions. If you earn a high salary and contribute aggressively, you might reach this limit by mid-year—say, June. Once you hit the cap, payroll stops deducting contributions, and your employer's match stops, too. This creates a problem: you've contributed your maximum for the year, but you haven't received the full year's worth of employer match.

Example: You earn $180,000 and want to contribute 13.3% to reach the $24,000 limit. If you spread this evenly across 12 months, you'd contribute roughly $2,000/month and receive a monthly match. But if you contribute $24,000 by June (because that's how your payroll cycles work), you've maxed out and stop contributing July–December. Your employer, whose match is based on your contribution, also stops matching those six months.

A true-up provision fixes this by calculating what your employer would have contributed for a full year of contributions and depositing the difference at year-end. It ensures you're not penalized for high savings.

How a True-Up Works: The Mechanics

True-ups typically work like this: After the year ends, the plan administrator calculates two numbers:

1. Actual match: The match you received throughout the year based on your actual paycheck-by-paycheck contributions.
2. Projected full-year match: The match you would have received if you'd contributed consistently all 12 months (spread evenly if you hit the limit early).

If the projected full-year match is higher, the employer deposits the difference as a "true-up" contribution, usually by end of March of the following tax year.

Example: Earning the True-Up

You earn $160,000 annually. Your employer offers a 100% match on the first 3% you contribute. Your match formula would be $160,000 × 3% = $4,800 per year.

Scenario: Without spreading correctly

You contribute $24,000 by June (jumping 15% instead of spreading 12.5% evenly). June is month 6 of 12, so you've contributed 50% of the year's match: roughly $2,400. Then payroll stops contributions (you've hit the limit), and you receive no match July–December. Your actual match is $2,400.

The true-up calculation:

• Projected full-year match (if you'd spread evenly): $4,800
• Actual match received: $2,400
• True-up deposit: $4,800 − $2,400 = $2,400

In late March, your employer deposits $2,400 to your 401(k) as a true-up. You've recovered the missed match.

Scenario: With even spreading

Instead, you spread your $24,000 across 12 months at $2,000/month. Each month you contribute $2,000 (12.5% of your $160,000 salary), which is above the 3% match cap. Your employer matches 3% ($4,000/year ÷ 12 = $333.33/month) every month. Over the year, you receive $4,000 in match—the full amount. No true-up is needed because you received the full match throughout the year.

Who Has True-Up Provisions?

True-up provisions are found primarily in:

• Large corporations with sophisticated benefits departments
• Plans serving high-income employees (executives, partners at professional firms)
• Government and university 401(k) plans (403(b) and 457(b) plans more commonly have true-ups)
• Plans administered by specialized providers (Fidelity, Vanguard, others)

Small to mid-size companies often don't have true-ups because the administrative burden is deemed not worth the cost for employees who might max out contributions.

The Case for True-Ups: Who Benefits

True-ups are most valuable for high earners who:

1. Contribute aggressively and might max out before year-end
2. Don't control their salary timing (e.g., commissions, bonuses bundled early in the year)
3. Have variable income that's front-loaded or back-loaded

For modest earners who won't hit the $24,000 limit, a true-up is irrelevant. If you contribute only 10% of salary and your salary is $60,000, you'll contribute just $6,000—far below the limit—so no true-up is needed.

Checking if Your Plan Has a True-Up

Your plan document (Summary Plan Description) will specify whether a true-up provision exists. Look for language like:

"Employer Match True-Up Provision: Any shortfall between the match that would have been made if the employee contributed consistently throughout the year and the match actually made shall be contributed to the employee's account by March 31 of the following year."

If you don't see this language, ask HR or your plan administrator directly: "Does our 401(k) plan have a true-up provision?" A simple yes or no will tell you whether this safety net exists.

True-Up vs. Automatic Adjustment

Some plans with sophisticated payroll systems automatically spread high earners' contributions evenly across the year to avoid early maxouts. This is different from a true-up. If your payroll system auto-adjusts, you won't need a true-up because you'll hit the limit naturally on December 31, not June. Check whether your payroll system does this; it's another way to preserve the full match.

Real-World Examples

Example 1: The high-earning maxer with no true-up Derek earns $200,000 and works at a mid-size firm with no true-up provision. He decides to contribute $24,000 to max out his 401(k), but his payroll cycles are monthly and he directs $2,000/month contributions. By December, he's contributed his full $24,000 and received 12 months of employer match (3% of salary = $6,000/year). No problem—because he spread the contributions evenly, he got the full match. If instead he'd tried to contribute $24,000 all in January, payroll would have processed only one month's contribution, and he'd receive only one month's match ($500). Without a true-up, he'd be out of luck for the rest of the year.

Example 2: The bonus-heavy earner with a true-up Maria earns a $150,000 base salary plus a $50,000 year-end bonus. She contributes $24,000 to her 401(k) across the year. Her employer offers a 3% match ($150,000 × 3% = $4,500). In months 1–11, she contributes roughly $2,000–$2,500 per month and receives a proportional match. In December, she receives a $50,000 bonus and attempts to contribute it to her 401(k), but she's already maxed out ($24,000), so no additional contributions are processed, and no additional match is calculated. Her actual match is about $4,000 (proportional to her even contributions). Her company's true-up provision kicks in: the plan calculates that if Maria had been able to contribute evenly across all 12 months and months' of income, her match should be $4,500. The company deposits $500 as a true-up in January. Maria receives her full match despite the bonus timing.

Example 3: The consultant without a true-up Alex is a consultant earning $250,000 at a firm with no true-up. He wants to maximize retirement savings and plans to contribute $24,000, but his income is lumpy: he bills $60,000 in Q1, $40,000 in Q2, and $150,000 in Q3. He's tempted to bulk-contribute in Q1 when cash is available, but he realizes this would result in early maxout and lost match. Instead, he spreads his contributions evenly: $2,000/month. This ensures he receives the full match all 12 months. By December, he's contributed $24,000 and received the full annual match, despite the lumpy income.

Common Mistakes

Mistake 1: Assuming a true-up exists when it doesn't Many high earners believe their plans have true-ups and contribute aggressively early in the year without checking. No true-up = early maxout = lost match. Always verify your plan's actual rules before contributing aggressively.

Mistake 2: Not spreading contributions to prepare for maxout If your plan lacks a true-up, you must manage your contributions carefully to avoid early maxout. Divide your target contribution by 12 or 26 (depending on paycheck frequency) and set that as your deferral percentage. Don't guess.

Mistake 3: Forgetting to verify the true-up deposit If your plan has a true-up, you should see a true-up deposit on your 401(k) statement by March 31. If you don't see it by April 15, contact your benefits department. Processing errors can happen; follow up to ensure you received what you're owed.

Mistake 4: Bunching contributions without understanding the impact Some people think it doesn't matter when they contribute during the year. It does, if there's no true-up. Contributing $24,000 in January and $0 for the rest of the year results in match for only one paycheck. Spreading it ensures match for all 12 months.

Mistake 5: Not negotiating for a true-up as part of compensation If you're a high earner at a company without a true-up, you might negotiate one as part of your compensation package or employment agreement. It's worth asking, especially if you're senior or in a competitive role.

FAQ

Q: If I have a true-up, can I contribute as much as I want early in the year?

A: You can contribute up to the $24,000 limit anytime throughout the year; payroll will stop processing contributions once you hit the limit. A true-up doesn't allow you to exceed the limit—it just ensures the match is calculated as if you'd spread contributions evenly. Contribute as aggressively as you want early in the year if you have a true-up; you'll receive the full match at year-end.

Q: When does the true-up deposit appear in my account?

A: Typically by March 31 of the following tax year. Some plans deposit earlier (by February 28 or December 31), and some later (by April 15). Check your plan document for the specific deadline. If you don't see the deposit by the plan's deadline, contact your benefits department.

Q: Does the true-up contribution count toward the annual contribution limit?

A: Yes and no. Your own contributions count toward the $24,000 deferral limit. The true-up is an employer contribution and counts toward the $70,000 aggregate limit (2024–2025), not the employee deferral limit. This is a technical distinction but doesn't usually affect employees unless they have very high income and multiple employers.

Q: Can I roll over a true-up contribution to an IRA?

A: Yes. A true-up is an employer contribution and can be rolled over along with the rest of your vested 401(k) balance to an IRA or a new employer's 401(k) when you change jobs.

Q: Is a true-up the same as catch-up contributions?

A: No. Catch-up contributions are an IRS rule allowing people age 50+ to contribute an extra $8,500 (2024–2025), bringing their total deferral limit to $32,500. A true-up is an employer discretionary feature that compensates for missed match. They're separate mechanisms.

Q: Can my employer reduce or eliminate the true-up?

A: Yes. An employer can amend the plan to remove the true-up provision with appropriate notice. However, removing a true-up is rare because it reduces the attractiveness of the plan and the organization's ability to recruit and retain talent. If your employer mentions eliminating the true-up, it's worth understanding the impact on your compensation.

Summary

A true-up provision is a valuable feature that compensates employees for early maxout of 401(k) contributions. If you hit the annual deferral limit before year-end, a true-up calculates the match you would have received for the full year and deposits the difference by March 31. True-ups are most useful for high earners but are not common in small to mid-size plans. Always check your plan document to confirm whether a true-up exists. Without a true-up, spread contributions evenly across the year to capture the full employer match. If you're a high earner at a company without a true-up, negotiate one as part of your compensation. Tax rules and plan provisions change; confirm current rules with your plan administrator or the IRS.
