Estimate your total 2026 SIMPLE IRA contribution. Models the $17,000 employee salary deferral, the SECURE 2.0 $18,100 small-employer limit, the $4,000 age-50 and $5,250 age 60-63 catch-ups, the employer 3% match versus 2% nonelective contribution, and your estimated federal income tax saved.
Want the full statutory background, the employer match versus nonelective decision, the SECURE 2.0 changes, the 2-year/25% rule, Roth SIMPLE deferrals, and how a SIMPLE IRA compares to a SEP IRA and a 401(k)? Read the companion authority guide.
Read the SIMPLE IRA Contribution Limits Guide →For 2026 you can defer up to $17,000 of your salary into a SIMPLE IRA, plus a $4,000 catch-up at age 50 to 59 or 64+, or a higher $5,250 catch-up at age 60 to 63. Certain small-employer plans use a higher $18,100 employee limit under SECURE 2.0. On top of your deferral, your employer must add either a dollar-for-dollar match up to 3% of your pay (no compensation cap) or a 2% nonelective contribution on compensation up to $360,000. The traditional deferral is pre-tax for income tax but still pays Social Security and Medicare tax. The 2025 employee limit was $16,500 with a $3,500 catch-up.

This calculator applies IRS Notice 2025-67 (2026 retirement plan COLA limits), the SIMPLE IRA framework in IRC section 408(p), and the SECURE 2.0 Act changes in sections 109 (age 60 to 63 catch-up) and 117 (higher small-employer limit). The calculation proceeds in four steps. For the full background, see our SIMPLE IRA Contribution Limits Guide.
The base employee salary reduction limit under IRC section 408(p)(2)(E) for 2026 is $17,000 in a standard SIMPLE plan, or $18,100 in a section 117 enhanced small-employer plan (was $16,500 / $17,600 for 2025). Your planned deferral is capped at this base limit plus any catch-up.
Workers age 50 to 59 and age 64 or older add a $4,000 catch-up in a standard plan ($3,850 in a section 117 plan) for 2026. Workers age 60, 61, 62, or 63 add a higher $5,250 catch-up under SECURE 2.0 section 109. The catch-up is part of your own salary deferral, not an employer contribution.
The employer chooses one formula:
Your total annual contribution is the employee deferral (with catch-up) plus the employer contribution. The estimated income tax saved is your pre-tax deferral multiplied by your marginal federal rate. A traditional SIMPLE deferral is excluded from box 1 of your W-2, but it is still subject to Social Security and Medicare (FICA) tax, so the FICA is not reduced.
| Feature | SIMPLE IRA | SEP IRA | 401(k) |

| Employee deferral | $17,000 ($18,100 small-employer) | None | $24,500 |
| Catch-up age 50 (2026) | $4,000 ($5,250 at 60-63) | None | $8,000 ($11,250 at 60-63) |
| Employer contribution | Mandatory 3% match or 2% nonelective | Up to 25% of comp ($72,000 cap) | Optional match / profit share |
| Best for | Small employers wanting employee deferrals | Self-employed, larger discretionary contributions | Larger employers, highest deferral |
| Employer size | 100 or fewer employees | Any | Any |
| Early-withdrawal penalty | 25% in first 2 years, then 10% | 10% | 10% |

If you are self-employed and want to contribute much more than a SIMPLE IRA allows, compare a SEP IRA and a Solo 401(k) in our SEP IRA vs Solo 401(k) Calculator. For a workplace 401(k), see the 401(k) Contribution Calculator.
Example 4 shows why the 2% nonelective matters: a non-deferring employee still receives an employer contribution, while the 3% match would give them nothing. Example 3 shows the age 60 to 63 catch-up pushing one person's own deferral to $22,250 in a single year.
The mistake we see most with SIMPLE IRA owners at LMN Tax Inc. is the small-business owner who assumes the plan caps total savings the way the headline $17,000 deferral suggests, and never realizes the 3% match has no compensation cap. An owner paying themselves $200,000 who defers the full $17,000 plus a $4,000 catch-up, and elects the 3% match, adds another $6,000 of employer money ($200,000 times 3%) on top, for $27,000 in one year through a plan most people think of as small. The second pattern is the owner who picks the 2% nonelective to avoid paying the full 3% match, not realizing it locks in a contribution for every eligible employee whether or not they defer, which can cost more when most of the staff does not participate. We always run both formulas against the actual payroll before the November 2 election deadline. And we flag the 2-year clock for anyone who might need the money early: a distribution in the first two years before age 59½ is taxed at a 25% penalty, not the usual 10%, so a SIMPLE IRA is a poor place for money you may need soon.
Defer at least enough to capture the full 3% match, then push toward the $17,000 limit if your budget allows. Set a per-paycheck amount that reaches your target by year-end, and add the catch-up if you are 50 or older. Submit your deferral election within the 60-day window your employer provides.
Run both employer formulas against your actual payroll before the election deadline. The 3% match rewards employees who defer; the 2% nonelective pays everyone. Owners can stack their own $17,000 deferral plus catch-up on top of the uncapped 3% match for a larger total than the headline limit suggests.
A SEP IRA or Solo 401(k) usually allows far larger contributions for the self-employed. Compare the ceilings in the SEP IRA vs Solo 401(k) Calculator before the next plan year, since an employer cannot run a SIMPLE IRA and another plan in the same year.
A SIMPLE IRA makes you an active participant, which can phase out your traditional IRA deduction. Check the interaction in the Traditional IRA Deduction Calculator, and consider a Roth IRA if your deduction is limited.
