The Basics of SIMPLE IRAs

The SIMPLE IRA, or Savings Incentive Match Plan for Employees, is a retirement vehicle designed specifically for small businesses with 100 or fewer employees. It serves as an accessible alternative to the more complex 401(k), offering lower administrative costs and fewer regulatory hurdles for the employer. While it functions similarly to a Traditional IRA in that contributions are made pre-tax and grow tax-deferred, the SIMPLE IRA is a workplace-sponsored plan that requires participation from both the employer and the employee.

For the 2026 tax year, the standard employee contribution limit has increased to $17,000, up from $16,500 in 2025. Employees age 50 or older are eligible for a catch-up contribution of $4,000, bringing their total possible deferral to $21,000. Under the SECURE 2.0 Act, certain very small businesses with 25 or fewer employees may allow even higher “enhanced” limits of $18,100, plus a catch-up of $3,850 for those 50 and older. Starting in 2026, a new “super” catch-up limit of $5,250 is also available specifically for participants aged 60 through 63.

A defining feature of the SIMPLE IRA is the mandatory employer contribution, which ensures that all eligible employees receive some form of retirement funding. Employers generally must choose between two options: matching employee contributions dollar-for-dollar up to 3 percent of their compensation or making a “non-elective” 2 percent contribution for every eligible employee regardless of whether the employee contributes their own money. This requirement makes the SIMPLE IRA a valuable benefit for workers, as it guarantees employer participation in their retirement savings.

Vesting rules in a SIMPLE IRA are among the most employee-friendly in the retirement landscape. Unlike 401(k) plans, which often require several years of service before an employee “owns” the employer’s matching funds, all contributions to a SIMPLE IRA are 100 percent vested immediately. This means that every dollar deposited by the employer belongs to the employee the moment it hits the account, and they can take the full balance with them if they leave the company, regardless of their length of tenure.

One unique and critical rule for SIMPLE IRAs is the “two-year rule” regarding withdrawals and rollovers. If a participant takes a distribution from their SIMPLE IRA within the first two years of their initial participation in the plan, they are subject to a steep 25 percent early withdrawal penalty—significantly higher than the standard 10 percent penalty for other IRAs. Additionally, during this same two-year window, funds can only be rolled over into another SIMPLE IRA; they cannot be moved into a Traditional or Roth IRA until the two-year period has elapsed.
