Money Purchase Pension Plan

A Money Purchase Pension Plan is a defined-contribution retirement plan that requires employers to contribute a fixed percentage of eligible employee compensation annually, regardless of company profitability. Unlike discretionary profit-sharing arrangements, the contribution formula is mandatory and predictable.

Fixed contributions create funding certainty

The defining feature of a money purchase pension plan is the mandatory, formulaic employer contribution. An employer might commit to contributing 10% of eligible compensation annually—10% for the first employee, 10% for all employees, every year, profit or loss. This obligation is contractual and enforceable; the IRS takes noncompliance seriously, imposing penalties and potential plan disqualification.

This rigidity creates both advantage and disadvantage. Employers gain absolute predictability: they know their retirement costs will be, say, 10% of payroll, facilitating budgeting and financial forecasting. Employees benefit from guaranteed accumulation—they know precisely what the employer will contribute each year. There is no guessing whether business performance will yield a bonus contribution or a zero year.

Conversely, businesses with volatile revenues face a burden. A construction company that earned $5 million last year but only $1 million this year must still contribute its percentage to the plan, straining cash flow. This inflexibility makes money purchase plans less attractive to cyclical industries than Profit Sharing Plans, which allow discretionary variation.

Contribution formula and limits

The contribution formula is specified in the plan document and can vary in sophistication. Simple formulas state a flat percentage of compensation (e.g., “8% of salary for all participants”). More complex formulas might vary by employee classification—for example, 8% for full-time employees and 4% for part-time employees. Some plans incorporate age or tenure components, allocating higher percentages to older or longer-tenured workers, though such provisions require careful actuarial review to avoid nondiscrimination violations.

The maximum contribution is capped at 25% of eligible payroll (or the annual defined-contribution limit, currently $69,000 for 2024, adjusted annually). This ceiling allows substantial tax deferral, particularly for owners of profitable businesses. A self-employed consultant earning $400,000 annually can contribute up to 20% of net self-employment income (after accounting for self-employment tax deductions), deferring up to approximately $58,000 annually—a powerful wealth-accumulation tool.

Unlike 401(k) plans where employee deferrals are flexible, all contributions in a money purchase plan flow from the employer. Employees cannot boost their retirement savings through additional elective deferrals (unless the plan separately includes a 401(k) component, which some money purchase plans do, though this is uncommon).

Vesting and employee incentives

Money purchase plans can implement multi-year vesting schedules—typically 3-year cliff vesting (all-or-nothing at the 3-year mark) or 6-year graded vesting (20% per year, fully vested after six years). This flexibility allows employers to retain staff: an employee departing before vesting completes forfeits unvested contributions, which revert to the plan and can be reallocated to remaining participants.

The vesting feature creates an interesting tension. Employees accrue employer contributions regardless of their tenure or engagement, but they only keep those contributions if they remain employed through the vesting schedule. This encourages long-term commitment while protecting employers from subsidizing transient workers.

Safe Harbor 401(k) plans, by contrast, require immediate vesting of employer contributions. This means a money purchase plan can be a more cost-effective retention tool for employers prioritizing long tenure, while safe harbor plans are appropriate for employers emphasizing broad employee benefit access.

Administrative requirements and compliance

Money purchase plans must have a written plan document, maintain participant records, provide annual statements, and comply with annual nondiscrimination testing. The Actual Contribution Percentage (ACP) test ensures that highly compensated employees do not receive disproportionate contributions. In practice, this test is rarely failed because contributions are uniformly formula-based, but employers must still perform and document the test annually.

Employers must file Form 5500 with the Department of Labor if the plan exceeds $250,000 in assets. Third-party plan administrators typically charge $2,000–$5,000 annually for small to mid-sized plans. For self-employed individuals, a solo money purchase plan can be administered with minimal overhead, making it cost-effective compared to larger corporate plans.

Contributions must be made by the employer’s tax-filing deadline (including extensions). Missing a contribution deadline can trigger IRS penalties and, in severe cases, plan disqualification. This firm requirement contrasts with Profit Sharing Plans, where missed contributions in zero-profit years are sometimes tolerable if the plan specifically allows discretionary funding.

Choosing between money purchase and profit sharing

The trade-off is philosophical and practical. Money purchase plans suit employers that are consistently profitable, want predictable retirement costs, and value the motivational clarity of a guaranteed employer contribution. Law firms, established consulting practices, and utility companies often prefer money purchase arrangements.

Profit Sharing Plans are better for cyclical businesses or those with irregular earnings. They preserve cash-flow flexibility while maintaining employee alignment with profitability. A business might couple a modest profit-sharing plan with a 401(k) component, allowing employee deferrals to absorb savings in low-profit years.

Some sophisticated business owners maintain both structures. For example, a business might operate a money purchase plan at a modest 4% contribution level (ensuring baseline retirement funding), coupled with a profit-sharing plan that contributes an additional percentage in profitable years. This balances predictability with upside participation.

Integration with other retirement vehicles

Money purchase plans can be integrated with an elective deferral (401(k)) component, though this is less common than in profit-sharing arrangements. When combined, the plan documents separately track employee deferrals and employer contributions, subject to different rules and limits.

Self-employed individuals can also maintain both a money purchase plan and a traditional IRA, though the IRA contribution limit (currently $7,000) is modest compared to the money purchase allowance. Many business owners prioritize maxing out the money purchase plan before funding an IRA.

Exit and dissolution scenarios

If an employer discontinues a money purchase plan, all unvested contributions immediately vest, and the plan must distribute all assets to participants or transfer them to successor plans. This vesting acceleration is required by law, ensuring departing employees cannot be forfeited due to plan termination. The termination also triggers administrative costs—final Form 5500 filing, actuarial valuations (if any benefits are promised), and distribution processing.

Employers should be aware that plan termination is neither tax-free nor reversible. Once terminated, the plan cannot be reinstated unless the IRS grants a favorable determination. For employers considering retirement plan flexibility, a profit-sharing plan or safe harbor 401(k) may be more suitable than a money purchase plan’s rigid commitment.

Historical context and modern prevalence

Money purchase plans were more common before the 1980s, when defined-benefit pensions dominated employer retirement planning. The rise of 401(k)s and the flexibility of profit-sharing plans shifted preferences away from rigid money purchase arrangements. Today, they remain popular among self-employed professionals and small closely held businesses but are less prevalent among large employers.

Their endurance reflects genuine utility: for a business owner with stable income and a preference for certainty, a money purchase plan remains an efficient, tax-advantaged wealth-accumulation vehicle. The mandatory contribution imposes discipline, ensuring retirement savings occur regardless of discretionary temptation.
