1. Purpose & Scope
1.1 This policy establishes the framework for the Organization's 401(k) defined contribution retirement savings plan, offered as a core employee benefit to support long-term financial security and retirement preparedness. The plan is established and maintained under Section 401(k) of the Internal Revenue Code (IRC) and is governed by the Employee Retirement Income Security Act (ERISA) of 1974, as amended. This policy covers plan eligibility, employee and employer contribution structures, vesting schedules, investment options, distribution rules, fiduciary responsibilities, and participant rights. The plan shall be administered in accordance with the plan document, the summary plan description (SPD), and all applicable IRS, Department of Labor (DOL), and Pension Benefit Guaranty Corporation (PBGC) regulations. This policy applies to all eligible employees of the Organization working in the United States.
1.2 The Organization shall appoint a Plan Administrator who shall serve as the named fiduciary responsible for the day-to-day administration of the 401(k) plan, including participant enrolment and eligibility verification, contribution processing and reconciliation, regulatory filings (Form 5500, Summary Annual Report), non-discrimination testing (ADP/ACP tests, top-heavy testing), and participant communications including the Summary Plan Description, quarterly statements, and required notices. The Organization shall engage a qualified recordkeeper to maintain participant accounts and process transactions, a custodian or trustee to hold plan assets, and an independent investment advisor (3(21) or 3(38) fiduciary) to assist with the selection and monitoring of the plan's investment menu. The Plan Administrator shall ensure that all fiduciary duties are discharged solely in the interest of participants and beneficiaries and with the care, skill, prudence, and diligence required under ERISA Section 404.
2. Eligibility & Enrolment
2.1 All employees who are aged 21 or older and have completed 90 calendar days of continuous employment with the Organization are eligible to participate in the 401(k) plan. Seasonal, temporary, and part-time employees who work fewer than 1,000 hours in a 12-month period may be excluded, as permitted under ERISA Section 202. Eligible employees shall be automatically enrolled in the plan at a default pre-tax contribution rate of 3% of eligible compensation, with automatic annual escalation of 1% per year up to a maximum of 10%, in accordance with ERISA Section 514(e) safe harbour provisions for automatic contribution arrangements. Employees shall receive written notice at least 30 days before the auto-enrolment effective date and shall have 30 days to modify their contribution rate, change their contribution type (pre-tax, Roth, or a combination), or opt out entirely. Employees who opt out may enrol or re-enrol at any time during the plan year.
2.2 Employee elective deferrals shall not exceed the annual limit established by the IRS under IRC Section 402(g), which is $23,000 for the 2024 tax year (subject to annual cost-of-living adjustments published by the IRS). Employees who have attained age 50 or older by the end of the calendar year may make additional catch-up contributions up to the limit established under IRC Section 414(v), which is $7,500 for 2024. Participants may elect to make pre-tax deferrals, designated Roth after-tax deferrals under IRC Section 402A, or a combination of both, provided total deferrals do not exceed the applicable annual limit. The Payroll department shall monitor cumulative deferrals throughout the year and shall automatically stop contributions when the annual limit is reached, resuming deferrals at the start of the next plan year. Excess deferrals shall be corrected in accordance with IRS correction procedures.
3. Employer Contributions & Vesting
3.1 The Organization shall make a matching contribution equal to 100% of the first 4% of eligible compensation that each participating employee defers to the plan during the plan year. The matching contribution shall be calculated and deposited on a per-pay-period basis and trued up at the end of the plan year to ensure that employees who reach the deferral limit mid-year receive the full match. Employer matching contributions shall vest according to a 3-year graded vesting schedule as follows: 33% vested after completing 1 year of service, 66% vested after 2 years of service, and 100% vested after 3 years of service. For vesting purposes, a year of service is defined as a 12-month period during which the employee completes at least 1,000 hours of service, as permitted under ERISA Section 203. Employee elective deferrals are always 100% immediately vested. Upon separation of employment, any unvested employer matching contributions shall be forfeited and allocated to the plan's forfeiture account, which shall be used to reduce future employer contributions or pay plan administrative expenses, as specified in the plan document.
3.2 The Organization may, at the sole discretion of the Board of Directors, make an additional discretionary profit-sharing contribution to the plan based on the Organization's annual financial performance. The amount and allocation method of the profit-sharing contribution shall be determined annually by the Board after the close of the fiscal year and shall be communicated to participants in the Summary Annual Report. Profit-sharing contributions may be allocated pro-rata based on eligible compensation or using an integrated allocation method that considers Social Security wage base, as permitted under IRC Section 401(l). Profit-sharing contributions shall vest on the same 3-year graded vesting schedule as employer matching contributions. The Organization is not obligated to make a profit-sharing contribution in any year and the decision to contribute, and the amount thereof, shall not create an expectation or entitlement for future contributions.
4. Investments & Participant Rights
4.1 The plan shall offer a diversified menu of investment options selected and monitored by the Plan Administrator with the assistance of the independent investment advisor, in compliance with ERISA Section 404(c). The investment menu shall include, at a minimum: a series of target-date retirement funds (qualified default investment alternatives, or QDIAs, for auto-enrolled participants), domestic and international equity index funds, a fixed income/bond fund, and a capital preservation option (stable value fund or money market fund). All investment options shall be evaluated at least quarterly based on performance, fees, risk-adjusted returns, and peer group comparisons, and the investment lineup shall be reviewed and updated as necessary at least annually. Participants are responsible for directing the investment of their own account balances among the available options and may change their investment elections at any time. The Organization and the Plan Administrator shall not provide individual investment advice but shall make financial wellness resources and access to the plan's investment advisor available to all participants.
5. Distributions, Loans & Compliance
5.1 Distributions from the plan are permitted upon the occurrence of a distributable event as defined under IRC Section 401(k)(2), including separation from service, attainment of age 59-1/2, permanent disability as defined under IRC Section 72(m)(7), death of the participant, or a qualifying financial hardship as defined under Treasury Regulation Section 1.401(k)-1(d)(3). Required minimum distributions shall commence no later than April 1 following the later of the calendar year the participant attains age 73 (as amended by the SECURE 2.0 Act) or the calendar year the participant separates from service (unless a 5% owner). Participant loans are available up to the lesser of $50,000 (reduced by the highest outstanding loan balance in the preceding 12 months) or 50% of the participant's vested account balance, with a minimum loan of $1,000. Loans must be repaid in substantially level payments over a period not exceeding 5 years (15 years for loans used to acquire a primary residence). The plan shall undergo annual non-discrimination testing (ADP/ACP tests under IRC Sections 401(k)(3) and 401(m)(2)), top-heavy testing under IRC Section 416, and coverage testing under IRC Section 410(b). Form 5500 shall be filed annually with the DOL, and this policy shall be reviewed at least annually to reflect legislative changes, IRS guidance, and evolving best practices.
What Is a 401(k) and Retirement Benefits Policy?
A 401(k) and retirement benefits policy is a formal document that outlines the design, administration, and governance of an employer-sponsored 401(k) defined contribution retirement savings plan in the United States. The 401(k) plan, named after Section 401(k) of the Internal Revenue Code (IRC), allows employees to save for retirement on a tax-advantaged basis, with many employers providing matching contributions to incentivise participation.
The policy covers plan eligibility, employee contribution options (pre-tax and Roth), employer matching and profit-sharing contributions, vesting schedules, investment options, distribution rules, loan provisions, and the fiduciary responsibilities of the Plan Administrator and the organization. It is governed by the Employee Retirement Income Security Act (ERISA) of 1974 and must comply with IRS regulations including annual non-discrimination testing.
A well-documented 401(k) policy ensures that the plan is administered consistently, that fiduciary duties are discharged prudently, that participants understand their rights and options, and that the organization maintains compliance with the complex regulatory framework governing retirement plans.
Why a Formal 401(k) Policy Is Essential
A 401(k) plan is both one of the most valued employee benefits and one of the most heavily regulated. ERISA imposes strict fiduciary duties on plan sponsors and administrators, requiring them to act solely in the interest of participants, follow the plan document, diversify investments, and pay only reasonable fees. Breaching these duties can result in personal liability for fiduciaries.
A documented policy provides the governance framework needed to meet these obligations. It defines who is responsible for plan administration, how investment options are selected and monitored, what the contribution and matching formulas are, and how the plan complies with IRS testing requirements. Without this documentation, fiduciary decisions are ad hoc and difficult to defend in the event of a DOL audit or participant lawsuit.
The SECURE Act and SECURE 2.0 Act have significantly expanded 401(k) requirements and opportunities, including auto-enrolment mandates for new plans, catch-up contribution changes, Roth employer contributions, and student loan matching. A formal policy ensures the organization stays current with these evolving requirements.
From an employee perspective, a 401(k) plan with clear documentation and employer matching is consistently ranked as one of the top three most-valued benefits. Employees who understand the plan — the match formula, vesting schedule, and investment options — participate at higher rates, defer more, and are more satisfied with their total compensation.
Key Components of a 401(k) Policy
An effective 401(k) policy includes plan eligibility criteria (age, service requirements, auto-enrolment provisions), employee contribution options (pre-tax, Roth, catch-up) with IRS annual limits, the employer matching formula (e.g., 100% of the first 4%) and true-up provisions, discretionary profit-sharing contribution provisions, the vesting schedule for employer contributions (e.g., 3-year graded), the investment menu structure and QDIA designation, distribution rules including hardship withdrawals and required minimum distributions, loan provisions with repayment terms, and fiduciary governance including the roles of Plan Administrator, trustee, recordkeeper, and investment advisor.
The policy should also address annual compliance requirements including ADP/ACP non-discrimination testing, top-heavy testing, coverage testing, and Form 5500 filing. For plans using auto-enrolment, the policy must describe the default contribution rate, automatic escalation schedule, and participant opt-out rights.
Fee transparency is increasingly important. The policy should describe how plan fees are allocated (paid by the plan, the employer, or participants), how fee reasonableness is assessed, and the frequency of fee benchmarking reviews.
How to Implement This 401(k) Policy
Start by selecting your plan service providers: a recordkeeper to maintain participant accounts, a custodian or trustee to hold plan assets, and an investment advisor (ideally a 3(38) discretionary fiduciary) to manage the investment menu. Negotiate fees and service level agreements, and document the selection process as evidence of prudent fiduciary process.
Draft or update the plan document and summary plan description (SPD) with legal counsel to reflect the terms in this policy. The plan document is the legal foundation — every administrative decision must be consistent with its terms. Distribute the SPD to all eligible employees.
Configure auto-enrolment in your payroll system at the default contribution rate (typically 3%) with automatic annual escalation of 1% up to 10%. Send the required 30-day advance notice to all eligible employees. Ensure the system correctly handles IRS deferral limits and catch-up contributions for employees aged 50+.
Establish an Investment Committee that meets at least quarterly to review investment performance, fees, and participant usage. Document every meeting with minutes that reflect the fiduciary analysis. Conduct annual plan audits (required for plans with 100+ eligible participants), complete non-discrimination testing, and file Form 5500 by the statutory deadline.
Provide participants with financial wellness resources and access to the plan's investment advisor. Employees who receive education and advice contribute an average of 2-3% more to their 401(k) and are significantly more likely to be on track for retirement readiness.
