To calculate a SIMPLE IRA employer match, take each employee’s salary deferral and match it dollar-for-dollar up to 3% of that employee’s annual compensation, or elect the alternative of a flat 2% nonelective contribution for every eligible employee. For 2026, the employee deferral limit is $17,000 (with higher limits for certain small employers under SECURE 2.0), the compensation cap that applies to the 2% nonelective formula is $360,000, and the match formula itself has no compensation ceiling.
Which Compensation Figure to Use
The match is calculated on gross compensation before the employee’s own deferral is subtracted. For W-2 employees, that means total wages, tips, and other pay subject to federal income tax withholding, plus any salary reduction contributions the employee made to the SIMPLE IRA or other employer-sponsored plans during the year.1Internal Revenue Service. IRS Publication 560
One point that catches employers off guard: the Section 401(a)(17) annual compensation limit only applies to the 2% nonelective contribution, not to matching contributions. For 2026, that cap is $360,000. When you use the match formula, there is no ceiling on the compensation used to calculate it.2Internal Revenue Service. SIMPLE IRA Plan An employee earning $400,000 who defers 3% receives a full $12,000 match, not one capped at the 401(a)(17) figure.
Running the Standard 3% Match
Under the standard formula, you match each employee’s salary reduction contributions dollar-for-dollar, up to 3% of that employee’s annual compensation.3Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts The match always equals the lesser of the employee’s actual deferral or 3% of compensation.
Two workers, same $60,000 salary. The first defers 5% of pay, or $3,000. Three percent of $60,000 is $1,800, so the employer contributes $1,800 even though the employee put in more. The second worker defers only 1%, or $600. The employer matches exactly $600, because the deferral itself is below the 3% ceiling.
Employees who choose not to contribute anything receive no match. The IRS has confirmed that an eligible employee may decline to make salary reduction contributions for a year, and in that case no employer matching contribution accrues.4Internal Revenue Service. Retirement Plans FAQs Regarding SIMPLE IRA Plans That makes the match cheaper when participation is low, and it also means non-participants get zero.
You can run the calculation each pay period or reconcile it as a year-end true-up. Either way, the full-year result must match what a dollar-for-dollar match up to 3% would produce on total annual compensation and total annual deferrals.
Reducing the Match Below 3%
An employer having a rough year may lower the match to as little as 1% for a given plan year under 26 USC 408(p)(2)(C)(ii). The restriction: you cannot use a rate below 3% in more than two out of any rolling five-year period.3Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts If you drop to 1% in 2025 and 2026, you must return to at least 3% for 2027, 2028, and 2029 before reducing again.
To use the reduced rate, you must notify all eligible employees of the lower percentage within a reasonable time before the 60-day election period that precedes the plan year.3Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts Miss the notice and you lose the right to use the lower rate, which pushes you back to a full 3% match.
The math works the same, just with a lower cap. Employee earning $50,000, defers 4%: the employer match at 1% is $500, even though the employee contributed $2,000.
The 2% Nonelective Alternative
Instead of matching individual deferrals, the employer can contribute a flat 2% of compensation for every eligible employee, whether or not those employees defer anything themselves.2Internal Revenue Service. SIMPLE IRA Plan It’s simpler to administer because you don’t track each person’s deferral rate, and every eligible employee gets something.
The nonelective contribution is subject to the $360,000 compensation cap for 2026, capping the largest single contribution at $7,200. An employee earning $40,000 receives $800. An employee earning $500,000 receives $7,200, because compensation above the cap is disregarded.2Internal Revenue Service. SIMPLE IRA Plan
You owe the nonelective contribution for every employee who met the plan’s eligibility requirements during the year, including those who left mid-year and those who chose not to defer any of their own pay.
How Self-Employed Owners Calculate Their Own Match
For self-employed individuals, compensation means net earnings from self-employment as shown on Schedule SE (Form 1040), line 4, before subtracting any SIMPLE IRA contribution you make for yourself.1Internal Revenue Service. IRS Publication 560 That Schedule SE figure already reflects the deduction for one-half of self-employment tax, so you don’t subtract it again. The 0.9% additional Medicare tax on high earners does not affect this calculation.
Say Schedule SE line 4 shows $80,000. You defer 3% ($2,400) and provide yourself a 3% match, so the employer piece is also $2,400. Total SIMPLE IRA contribution: $4,800. The match is calculated on the full $80,000, not on the amount left after your own deferral.
Where this gets circular is that your employer contribution is itself a deduction that reduces your income. Publication 560 provides rate tables and a worksheet in Chapter 3 that walk through the iterative calculation step by step for self-employed owners.
What Changes in 2026 Under SECURE 2.0
The employee deferral limit sets an outer bound on what the match can reach, because an employee can’t defer more than the annual cap. For 2026, the standard SIMPLE IRA employee deferral limit is $17,000. Employees age 50 and older can add a $4,000 catch-up contribution.5Internal Revenue Service. Retirement Topics – SIMPLE IRA Contribution Limits
SECURE 2.0 introduced several changes that affect employer calculations starting in 2026:
- Employees who are 60, 61, 62, or 63 at year-end can make catch-up contributions of $5,250 instead of the standard $4,000.5Internal Revenue Service. Retirement Topics – SIMPLE IRA Contribution Limits
- Employers with 25 or fewer employees automatically qualify for a higher deferral limit of $18,100. Employers with 26 to 100 employees can elect the same higher limit, but only if they increase the match to 4% of compensation or the nonelective contribution to 3%.6Internal Revenue Service. IRS Notice 2024-02 – Miscellaneous Changes Under the SECURE 2.0 Act
- Any employer can make an additional nonelective contribution of up to 10% of each eligible employee’s compensation, capped at $5,000 per employee. This sits on top of the standard match or 2% nonelective contribution.6Internal Revenue Service. IRS Notice 2024-02 – Miscellaneous Changes Under the SECURE 2.0 Act
The higher-limit election for 26-to-100-employee employers changes the match math meaningfully. Instead of matching up to 3%, those employers must match up to 4% of compensation. An employee earning $75,000 who defers 5% would receive a $3,000 match at the 4% rate, versus $2,250 at the standard 3% rate.
When You Have to Deposit the Match
Employer matching and nonelective contributions must be deposited by the due date for filing your business income tax return, including extensions.4Internal Revenue Service. Retirement Plans FAQs Regarding SIMPLE IRA Plans For a calendar-year sole proprietor filing a Schedule C, that’s typically April 15 of the following year, or October 15 with an extension. That runway lets you finalize the numbers after year-end, which matters for self-employed owners who won’t know their exact net earnings until the return is done.
Employee salary deferrals you withhold from paychecks are a different animal and move on a much shorter timeline. The IRS deadline is 30 days after the end of the month in which you withheld the money, but Department of Labor rules generally require deposit as soon as the funds can reasonably be segregated from the employer’s general assets, with a 7-business-day safe harbor for most SIMPLE IRA plans.7Internal Revenue Service.

Fixing a Miscalculated or Missed Match
If you excluded an eligible employee or failed to make the required employer contribution, the correction depends on the formula. Under a 3% match plan, you contribute 3% of the excluded employee’s compensation (assuming they would have deferred at least 3%), plus 50% of that missed deferral opportunity as a make-up contribution, plus earnings calculated from the date the contributions should have been made.8Internal Revenue Service. SIMPLE IRA Plan Fix-It Guide – You Excluded an Eligible Employee From Participating Under a 2% nonelective plan, you owe the 2% of compensation plus earnings.
Catch it fast and the penalty is lighter. When the failure period is less than three months and you correct promptly, no additional make-up contribution for the lost deferral opportunity is required, provided the employee begins participating and receives a special notice within 45 days.8Internal Revenue Service. SIMPLE IRA Plan Fix-It Guide – You Excluded an Eligible Employee From Participating For longer failures caught and fixed while the employee is still on staff, the corrective contribution for the missed deferral can be reduced from 50% to 25% if you meet specific timing requirements.
