As we move through 2026, the battle for the “Best Small-to-Midsize Business (SMB) Retirement Plan” has narrowed down to two giants: Fidelity Investments and Charles Schwab.
With the 2026 updates to the SECURE 2.0 Act now in full effect—including mandatory auto-enrollment for new plans and increased “catch-up” contributions for employees aged 60–63—business owners face a complex decision. Choosing between Fidelity and Schwab isn’t just about “low fees”; it’s about integration with your payroll, ease of IRS reporting, and the quality of the investment menu you provide to your employees.
1. Fidelity: The Institutional Retirement Heavyweight
Fidelity is the largest provider of 401(k) plans in the United States. In 2026, they have leveraged this scale to offer a “holistic” benefit ecosystem.
- The 2026 Advantage: Fidelity’s NetBenefits® platform is the gold standard for employee experience. It allows workers to see their 401(k), HSA, and stock options in a single view.
- Investment Selection: Fidelity offers its “Zero” expense ratio funds, which are a massive selling point for plan sponsors looking to minimize the “fiduciary drag” on employee returns.
- Solo 401(k) for Founders: For 2026, Fidelity’s Self-Employed 401(k) now supports Roth contributions natively, making it a top pick for high-earning freelancers.
- Best For: Companies looking for a “set it and forget it” solution with world-class employee education and planning tools.
2. Charles Schwab: The Flexibility and Simplicity Leader
Schwab has positioned itself in 2026 as the more “user-friendly” and flexible alternative for growing startups and professional service firms.
- The 2026 Advantage: Schwab’s Index Advantage® plan is specifically designed to keep costs low by using institutional-grade index funds. In 2026, they have significantly improved their automated 401(k) administration, reducing the paperwork burden for small business owners.
- Brokerage Link: Schwab remains the leader for “Self-Directed” employees. Through “BrokerageLink,” employees can move a portion of their 401(k) into a brokerage account to trade individual stocks or ETFs—a feature many tech-savvy employees demand in 2026.
- Integration: Schwab has better native integration with third-party payroll providers like Gusto and Rippling compared to Fidelity’s more proprietary approach.
- Best For: Startups and firms with sophisticated employees who want more control over their investment choices.

4. The 2026 SECURE 2.0 Compliance Check
Both firms have updated their platforms for 2026 to handle the latest IRS requirements. If you are starting a plan this year, you must ensure your provider handles:
- Automatic Enrollment: New plans (post-2025) must automatically enroll employees at a rate of 3% to 10%.
- Higher Catch-up Limits: For 2026, the catch-up limit for employees aged 60, 61, 62, and 63 has increased to $11,250 (up from $7,500 in previous years).
- Roth SIMPLE IRAs: If you choose a SIMPLE IRA instead of a 401(k), 2026 is the first year both Fidelity and Schwab fully support employer-contributed Roth options.
5. Pricing and Fiduciary Responsibility
A major change in 2026 is the increased scrutiny on Plan Sponsor Fiduciary Liability.
- Schwab tends to be more transparent with its “all-in” fee structures, making it easier for a small business owner to prove they are acting in the employees’ best interests.
- Fidelity offers deeper “Fiduciary Support Services,” where they take on more of the legal responsibility for investment selection, though this often comes with a higher administrative cost for the employer.
