Important deadlines for retirement contributions

SIMPLE IRA vs. SIMPLE 401(k) in 2026: Contribution Limits, Deadlines, and the 2-Year Rollover Rule Every Small Employer Needs to Know

Both SIMPLE plans share a $17,000 employee deferral limit for 2026, but they split on Form 5500 filing, participant loans, and the SIMPLE IRA's 25% early-distribution tax during its two-year rollover restriction.
