The 401(k) True-Up Provision: Don’t Lose Free Employer Money by Saving Too Fast

CORE INSIGHTS

  • The Pacing Trap: Maxing out your 401(k) early in the year can stop your employer match for the remaining months. “Speed” can cost you thousands.
  • True-Up Safety Net: A “True-Up” provision means the employer will fix this mistake at year-end. If your plan has it, you can front-load without fear.
  • Manual Calculation: If your plan lacks a True-Up, you must calculate the exact contribution % to hit the max ($23,500) on your final December paycheck.

For disciplined savers, reaching the IRS limit is a primary goal. However, most employers match on a “per paycheck” basis. If your contribution drops to 0% in October, the employer match also drops to $0. Without a True-Up, that money is lost forever.

What-If Scenario: The Eager Saver ($200k Salary)

Timeline Contribution Match (5%)
Jan – June $23,500 (Maxed) $5,000
July – Dec $0 (Stopped) $0 (Missed)
Result: Without True-Up, you lost $5,000 of free money by saving too fast.

Visualizing the Matching Gap

*Figure 1: The Gap. Green line (True-Up) catches up at year-end; Red line (No True-Up) flatlines early.*

Strategic Action Steps

1
Check the SPD
Search your Summary Plan Description for “True-Up” or “Reconciliation.” If unsure, email HR. This one clause determines your strategy.
2
Calculate Perfect Pace
If no True-Up: ($23,500 - Current Balance) / Remaining Paychecks. Set your % to hit this amount exactly.
3
Monitor Bonus Settings
Bonuses can accidentally max you out early. Consider turning off 401(k) contributions for bonuses to preserve space for regular payroll matching.

The Bottom Line: Who Should Choose What?

  • Plan Has True-Up: Max out as early as you want. Front-loading is fine.
  • Plan Has NO True-Up: You must be a “Pacing Sniper.” Spread contributions evenly until Dec 31st.

Frequently Asked Questions

What is a True-Up Provision?

A safety net clause. If you max out early and miss matches, the employer deposits the missing match as a lump sum at year-end.

Why does front-loading hurt the match?

Employers match per pay period. If you contribute $0 in a pay period (because you maxed out), the employer matches $0. You miss the free money for those weeks.

How do I check if I have a True-Up?

Check your Summary Plan Description (SPD) for terms like “Annual True-Up” or “Lookback Match.” If absent, assume you don’t have it.
