Sample 401(k) Communication Templates for Employees

Sample 401(k) communication templates for employees need to do more than sound friendly. Every notice you send has to state who is eligible, when they can enter the plan, how the employer match works, the current contribution limits, the vesting schedule, and how to reach the plan administrator. ERISA requires these disclosures in language an average participant can understand, and penalties for missing or incomplete notices reach into the thousands of dollars per day per affected participant.¹ The templates below cover the four communications most employers send, with the required elements built in and bracketed placeholders where your plan’s specifics go.

What Every 401(k) Notice Must Contain

Before customizing any template, confirm each of these appears somewhere in the communication:

Eligibility rules. Most plans require employees to be at least 21 and to have completed one year of service (generally 1,000 hours). Plans that provide immediate full vesting on employer contributions can extend the wait to two years for those contributions, but salary deferrals must always be permitted after no more than one year of service.²
Plan entry dates. When an eligible employee can actually start contributing. Many plans use quarterly entry dates (January 1, April 1, July 1, October 1); others allow monthly or immediate entry.
Employer match formula. Spell it out concretely, such as “50% of the first 6% of salary you contribute.” Vague match language is the single largest source of participant confusion.
Vesting schedule. Employer contributions must follow either cliff vesting (full vesting after three years of service) or graded vesting (20% in year two, rising to 100% by year six). Employee contributions are always 100% vested immediately.³
Plan administrator contact. Name, business address, and business telephone are required in every Summary Plan Description; carry them into your notices so employees know where to direct questions.⁴

All of this flows from ERISA’s requirement that participant disclosures accurately reflect current plan terms.⁵ Failing to provide required notices can trigger penalties of up to $2,112 per day for each affected participant, and ignoring a written participant request for plan documents carries a separate penalty of up to $190 per day.¹

2026 Numbers to Plug Into Any Template

Nothing dates a 401(k) communication faster than last year’s contribution limits. For 2026, employees can defer up to $24,500 from salary into a 401(k).⁶ The numbers get more complicated for older workers and high earners:

Standard catch-up for age 50 and older: an additional $8,000, bringing the total possible deferral to $32,500.⁶
Enhanced catch-up for ages 60 through 63: $11,250 instead of $8,000, for a total possible deferral of $35,750. This applies only if the plan has adopted the SECURE 2.0 provision.⁶
Mandatory Roth catch-ups for high earners: employees whose FICA wages from the prior year exceeded $150,000 must make all catch-up contributions on an after-tax Roth basis in 2026. If the plan doesn’t offer a Roth option, those employees lose the ability to make catch-up contributions at all.

Flag that last point on its own line in any communication that goes to a mixed audience. Employees who earned over $150,000 in 2025 and plan to keep making pre-tax catch-up contributions will be caught off guard otherwise.

Automatic Enrollment Notice

Plans established on or after December 29, 2022, must include automatic enrollment starting for plan years beginning after December 31, 2024. The initial automatic deferral rate must be at least 3% but no more than 10% of compensation, and must increase by 1 percentage point each year until it reaches at least 10%, with a ceiling of 15%. The notice below must go out at least 30 days (but no more than 90 days) before the first automatic contribution.⁷

Subject: You Will Be Automatically Enrolled in the [Company Name] 401(k) Plan

Dear [Employee Name],

Under the [Company Name] 401(k) Plan, you will be automatically enrolled beginning with your first paycheck on or after [Date]. Unless you take action, [X]% of your pre-tax compensation will be deducted from each paycheck and contributed to the plan.

Your contributions will be invested in the plan’s default investment option, [QDIA Fund Name], which is a [brief description, e.g., “target-date fund based on your expected retirement year”]. You can change your investment selections at any time through [Portal Link].

Your options:

Keep the default. No action needed. Your contribution rate will automatically increase by 1% each year until it reaches [X]%.
Change your rate. Log in to [Portal Link] to choose a different contribution percentage.
Opt out entirely. Log in to [Portal Link] and set your contribution rate to 0% before [Date].
Withdraw within 90 days. If your plan is an Eligible Automatic Contribution Arrangement and you decide within 90 days of your first automatic contribution that you do not want to participate, you can withdraw those contributions and any earnings without the usual early withdrawal penalties.⁸

[Company Name] matches [Match Percentage]% of the first [Contribution Limit]% of salary you contribute. Opting out means you will miss this matching contribution.

The attached QDIA notice and Summary Plan Description contain full details about the default investment fund and your rights under the plan. Contact [Plan Administrator Name] at [Phone Number] with questions.

Beneficiary Designation Reminder

Subject: Review Your 401(k) Beneficiary Designation

Dear [Company Name] Team,

Your 401(k) beneficiary designation controls who receives your account balance if something happens to you. If you are married and have not filed a designation, your spouse is the default beneficiary under federal law. Naming anyone other than your spouse requires your spouse’s written consent, which must be notarized or witnessed by a plan representative.

Confirm your designation is current, especially after a marriage, divorce, or birth of a child. Review or update your beneficiary through [Portal Link] or by contacting [Plan Administrator Name] at [Phone Number].

When to Send Each Notice

Safe harbor 401(k) plans must distribute their annual notice at least 30 days and no more than 90 days before the start of each plan year.⁹ The same 30-to-90-day window applies to automatic enrollment notices. New hires who become eligible mid-year need their notice before their first paycheck with automatic deferrals, not at the next annual enrollment window. Plan ahead for staggered hire dates.

Electronic and Paper Delivery

The DOL’s notice-and-access safe harbor allows plans to deliver ERISA disclosures electronically by default to any employee who has been provided or assigned a work email address. Before relying on electronic delivery for any individual, the administrator must send a one-time paper notification explaining that documents will be delivered electronically, identifying the email address that will be used, and informing the employee of the right to opt out of electronic delivery and receive paper copies at no charge.¹⁰

For employees without a work email or regular computer access (field workers, warehouse staff, and anyone without a desk email), send paper copies to their home address.

Keep a distribution log for every notice: the date, the delivery method, and the specific list of recipients. Save system-generated delivery confirmations for electronic sends and certified mail receipts or signed acknowledgment forms for paper. The goal is a clean paper trail showing every eligible participant received every required disclosure on time.

Documents a Template Email Cannot Replace

A well-written notice does not by itself satisfy ERISA. Several companion documents must reach participants on their own schedules:

Summary Plan Description. New participants must receive the SPD within 90 days of joining the plan. The SPD must reflect plan terms as of a date no earlier than 120 days before distribution.¹¹¹²
Summary of Material Modifications. When plan terms change in a way that affects benefits, eligibility, or operations, the SMM must go out within 210 days after the close of the plan year in which the change was made. Common triggers: changing the match formula, switching recordkeepers, adding a Roth option.¹³
Fee disclosures. An annual disclosure of plan-wide administrative fees that may be charged to individual accounts, plus quarterly statements showing the actual dollar amounts deducted from each participant’s account during the preceding quarter. Investment-specific expenses must also be disclosed for each investment option in the plan.¹⁴
QDIA notice. Any plan that defaults contributions into an investment when an employee makes no selection needs a Qualified Default Investment Alternative notice describing when money goes into the default fund, its investment objectives, and the participant’s right to move money out. It must go out at least 30 days before the first investment in the default fund, and again at least 30 days before each subsequent plan year.¹⁵

Review these documents at least annually against your most recent plan amendments. Distributing a stale SPD that contradicts current plan terms is one of the most common compliance failures.

If a Notice Was Missed

If an eligible employee wasn’t given the chance to make salary deferrals, the employer must generally make a corrective contribution called a Qualified Nonelective Contribution equal to 50% of the missed deferral. The missed deferral is calculated by multiplying the average deferral percentage for the employee’s group by their compensation for the period they were excluded.¹⁶ The corrective contribution must be fully vested and is subject to the same withdrawal restrictions as regular deferrals.

A reduced correction applies when specific conditions are met. If the excluded employee is still working when the error is caught and the exclusion lasted more than three months, the corrective contribution can be reduced to 25% of the missed deferral, provided the employee receives a special notice within 45 days of being given the opportunity to start contributing.¹⁶ If the exclusion lasted less than three months and the employee begins participating promptly with the required notice, no corrective contribution for the missed deferral is required.

All corrective contributions must be deposited into the plan before the end of the third plan year after the year the failure began. Catching errors early and correcting immediately is the single best way to minimize the financial hit. Before you send any of the templates above at scale, have your plan attorney review the final versions against your current plan document.
