Savings Incentive Match Plan for Employees setup, limits, and employer requirements
34% of U.S. small business owners have no retirement plan, and more than 80% of a typical owner's net worth sits inside the business. This guide compares the SEP IRA, Solo 401(k), and SIMPLE IRA at 2026 limits ($72,000, $24,500 deferral, $17,000), explains the SECURE 2.0 credits worth up to $5,000 a year for three years, and gives a five-step plan to start saving this quarter.
SECURE 2.0 gives small employers three stackable federal tax credits for starting a retirement plan — up to $5,000 per year for three years in startup costs, up to $1,000 per eligible employee in contribution credits, and a flat $500 per year for auto-enrollment — all claimed on IRS Form 8881. Here's who qualifies, how the five-year phasedown works, and how the credits compare against state auto-IRA mandates in 2026.
Massachusetts's House passed the Secure Choice Savings Program 148-2 on July 8, 2026, mandating auto-enrollment Roth IRAs for employers with 25+ workers — 6% default contributions, $250-per-employee penalties, and a qualifying-plan exemption small businesses can use to opt out entirely.
For 2026 the standard SIMPLE IRA elective deferral limit is $17,000, but employers with 25 or fewer employees (or 26-100 that raise their match) get an enhanced $18,100 limit under SECURE 2.0 — and a rounding quirk means the enhanced-tier catch-up contribution is actually lower than the standard one.
Compare the three most popular small business retirement plans—401(k), SEP IRA, and SIMPLE IRA—with 2026 contribution limits, pros and cons, and a decision framework to find the best fit for your business.
