Gusto 401(k) is the product formerly sold as Guideline, and the guideline.com pages now carry Gusto branding. Its pitch is a 401(k) built into payroll: automatic syncing between payroll and the plan, contributions and deductions handled for you, and compliance checks run daily with alerts and guided corrections when something is off. IRS form prep and filing is included, and Gusto says its automated tax credit forms can help reclaim up to 100% of plan costs. The company states that more than 40,000 businesses and 700,000 savers use the platform. Gusto's help center lists three plans, Starter, Core and Premium, but the plan prices did not load as text for our source checker, so we mark pricing as pending rather than repeat figures we could not verify. Its fee example also assumes an annual account fee of 0.25% on assets, so employees should expect an asset-based charge. It ranks fifth because the price could not be confirmed.
