Explore retirement plan options, contribution limits, and strategies for business owners
In 2026 a Solo 401(k) lets a self-employed owner shelter up to $72,000 ($83,250 with the ages 60–63 super catch-up) across a $24,500 employee deferral and a 25%-of-compensation employer contribution. This guide covers the two-bucket math, the new mandatory Roth catch-up for W-2 wages over $145,000, first-year vs. ongoing deadlines, and the $250,000 Form 5500-EZ filing trigger.
Under SECURE 2.0, any employee who works 500+ hours in two consecutive 12-month periods and is 21 or older must be allowed to defer into your 401(k) — even if your plan requires 1,000 hours. Here's what the IRS's final LTPT regulations require, who qualifies, and the rolling two-year hours-tracking system small businesses need to avoid missed-deferral corrections.
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.
SECURE 2.0 requires 401(k) and other defined contribution plans to mail at least one paper benefit statement per year starting with plan years after December 31, 2025. With Q1 2026 statements due around May 15 and the DOL's implementing rule still a proposal, Field Assistance Bulletin 2026-02 pauses enforcement for plan sponsors who comply in good faith — here's what small businesses must still do.
A safe harbor 401(k) automatically passes IRS ADP/ACP nondiscrimination testing in exchange for a fixed employer contribution — a 3% nonelective or a match of up to 4%. Here's how the three formulas compare in cost, the December 1 retroactive adoption deadline, and the 2026 limits ($24,500 deferral, $72,000 total additions, mandatory Roth catch-ups for high earners).
Starting January 1, 2026, SECURE 2.0's Section 603 requires workers 50 and older with over $150,000 in prior-year FICA wages from the same employer to make 401(k) catch-up contributions — $8,000 standard, $11,250 for ages 60–63 — as after-tax Roth. Plans without a Roth option must amend by December 31, 2026 or bar catch-ups entirely; W-2 S-corp owners are in scope while K-1 partners are not.
Texas federal courts vacated the DOL's Retirement Security Rule in March 2026, reverting fiduciary status for retirement advice to the 1975 five-part test — the second such rule struck down since 2018. Here's what 401(k) plan sponsors should check now: advisor fiduciary status in writing, compensation disclosures, and a documentation checklist, plus what the DOL's new alternative-assets safe harbor proposal means for small plans.
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.
SECURE 2.0 Section 110 lets employers match 401(k), 403(b), SIMPLE IRA, or governmental 457(b) contributions based on an employee's student loan payments instead of elective deferrals, and plan sponsors adopting the feature must formally amend their plan documents by December 31, 2026.
SECURE 2.0 requires new 401(k) and 403(b) plans established after December 29, 2022 to adopt an Eligible Automatic Contribution Arrangement with a 3% default deferral, 1% annual escalation up to a 10–15% cap, QDIA investment, and 90-day permissible withdrawal — with plan document amendments due by December 31, 2026.
A practical guide to ESOP repurchase obligation accounting for closely held companies — how ASC 480-10-S99 classifies redeemable shares as temporary equity, how to fund the obligation with sinking funds, COLI, recycling, and redemption, and the bookkeeping habits that keep plan-year valuations defensible.
