SIMPLE IRA Contribution Limits: Catch-Ups and Employer Match

Employees can defer up to $17,000 of pay into a SIMPLE IRA in 2026, and workers who are 50 or older can add another $4,000 on top of that.¹ On the employer side, every SIMPLE IRA requires a contribution from the business, either a match of up to 3% of compensation or a flat 2% non-elective contribution for every eligible worker. Two features of the plan change the math further in 2026: a higher deferral cap for employees at the smallest businesses, and a new “super catch-up” tier for workers in their early sixties.

Employee Deferral Limit for 2026

The baseline salary deferral limit is $17,000 for 2026.¹ Deferrals come out of your paycheck as pre-tax salary reductions, so each dollar you contribute lowers your taxable income by a dollar that year. You elect the amount by signing a salary reduction agreement with your employer, generally during the annual election period that runs from November 2 through December 31 for the following calendar year.²

Higher Limit at the Smallest Employers

The SECURE 2.0 Act created an enhanced deferral limit for employees at businesses with 25 or fewer workers. Those employees can defer 110% of the standard cap. Businesses with 26 to 100 employees can also offer the higher limit, but only if the employer agrees to a more generous matching or non-elective contribution than the usual minimums. Whether the higher limit applies to you depends on your employer’s size and, in the 26-to-100 range, on whether the employer opted in.

Catch-Up Contributions at 50 and Older

If you turn 50 by December 31 of the tax year, you can contribute an additional $4,000 on top of the $17,000 baseline, for a total possible deferral of $21,000 in 2026.¹ At businesses with 25 or fewer employees, the catch-up amount also rises to 110% of the standard figure.

The New Super Catch-Up at Ages 60 to 63

Starting in 2026, employees who are 60, 61, 62, or 63 can make catch-up contributions of up to $5,250 instead of the regular $4,000.³ For someone in that age window, the maximum deferral reaches $22,250. Once you turn 64, you drop back to the standard $4,000 catch-up tier.

Required Employer Contribution

A SIMPLE IRA is not optional for the employer. The business has to fund one of two formulas each year.

Dollar-for-Dollar Match Up to 3% of Pay

The most common formula is a dollar-for-dollar match on employee deferrals up to 3% of each worker’s compensation.⁴ One point that separates SIMPLE IRAs from most other plans: the 3% match is calculated on the employee’s full salary, not capped at the annual compensation limit that restricts contributions in a 401(k).² A worker earning $400,000 who defers 3% would receive a $12,000 match rather than one limited by the $360,000 compensation ceiling.

An employer can temporarily lower the match to as little as 1% of compensation in lean years, but only in no more than two years out of any rolling five-year period.⁴ Workers must be notified of the reduced percentage before the November 2 start of the election period.²

Flat 2% Non-Elective Contribution

The alternative is a flat 2% non-elective contribution that goes to every eligible employee, whether or not the employee defers anything.⁴ Unlike the 3% match, the 2% contribution is subject to the annual compensation limit of $360,000 for 2026, so the largest amount any single employee can receive through this route is $7,200.¹ The employer must choose between matching and non-elective before the year starts and tell employees which formula applies before the election period opens on November 2.²

Immediate Vesting

Every dollar the employer puts in belongs to the employee right away, along with any investment gains on those contributions.⁵ There is no vesting schedule to wait out, which is a real difference from many 401(k) plans that vest employer matches over three to six years.

Roth Deferrals

Section 601 of the SECURE 2.0 Act lets employers give participants the option of making salary deferrals on an after-tax Roth basis instead of the traditional pre-tax basis.⁶ Roth contributions do not reduce your taxable income the year you make them, but qualified withdrawals in retirement come out tax-free. The deferral limits are the same either way. Not every employer has added the Roth feature, so ask your plan administrator whether it is available.

When Contributions Must Be Deposited

Employee deferrals and employer contributions follow different deposit rules.

Withheld employee deferrals have to move into the SIMPLE IRA accounts as soon as they can reasonably be separated from the business’s general assets. Most plans qualify for a 7-business-day safe harbor, and the IRS sets an outside deadline of 30 calendar days after the end of the month in which the pay was withheld.⁷ Late deposits can trigger prohibited transaction excise taxes.

Employer contributions, whether matching or non-elective, have a longer runway. They must be deposited by the due date of the business’s federal income tax return, including extensions.⁴ For most businesses, that pushes the deadline to mid-March or mid-April of the following year, or later with an extension.

The Two-Year Rule

Contribution decisions carry a penalty risk that does not exist in most other retirement plans. If you pull money out of a SIMPLE IRA within two years of the date you first participated, the early-distribution additional tax jumps from the standard 10% to 25%, on top of regular income tax on the withdrawal. The same two-year clock also limits rollovers: during that window, you can only move SIMPLE IRA money to another SIMPLE IRA. A transfer to a traditional IRA, a 401(k), or any other non-SIMPLE account inside the two-year period is treated as a taxable distribution and hit with the 25% additional tax.⁸ The clock runs from the date you first participated in the plan, not from each individual contribution.
