Justworks Review 2026 - HR & Payroll

Justworks offers medical insurance plans from Aetna, UnitedHealthcare, and Kaiser Permanente in markets where Kaiser operates. Plan options include HMO, PPO, EPO, and high-deductible health plans with varying coverage levels and employee cost-sharing structures. Dental insurance is available through Guardian or MetLife, and vision insurance through VSP. The specific plans available depend on your company's state and the carrier options Justworks has negotiated for that market.

Beyond health insurance, Justworks administers 401(k) retirement plans through a partnership with Slavic401k, with options for employer matching contributions. Commuter benefits for transit and parking are available in cities with qualifying programs. Life insurance and accidental death and dismemberment coverage, short-term and long-term disability insurance, and health savings accounts or flexible spending accounts round out the benefits package.

The enrollment experience is designed for employees who may have never selected benefits before. Plan comparisons show monthly costs, deductibles, copays, and out-of-pocket maximums side by side. Each plan includes a plain-language summary alongside the formal summary of benefits and coverage document. Employees can model different scenarios to understand their potential costs under each plan.

Justworks runs payroll for every pay period automatically once you have configured pay rates, schedules, and deductions. The system calculates gross-to-net pay including federal income tax withholding based on W-4 elections, state income tax for the employee's work state and residence state if they differ, Social Security and Medicare contributions, and any pre-tax deductions for benefits, retirement contributions, and commuter programs.

Tax filing is fully handled by Justworks. After each payroll run, Justworks deposits withheld taxes with the appropriate federal, state, and local tax authorities on the required schedule. Quarterly 941 filings, annual 940 filings, state unemployment tax filings, and any applicable local tax filings are all completed by Justworks. Year-end processing generates W-2s for all employees and 1099s for contractors, files them with the IRS and Social Security Administration, and makes them available to employees through the self-service portal.

For companies with employees across multiple states � increasingly common with remote work � Justworks handles the complexity of multi-state payroll including reciprocal tax agreements, state-specific disability and family leave contributions, and varied unemployment insurance rates. When you hire your first employee in a new state, Justworks registers your company with the state tax authority and sets up unemployment insurance, eliminating a process that typically requires weeks of paperwork.

Justworks assigns compliance specialists who monitor federal, state, and local employment law changes that affect your workforce. When new regulations take effect � such as minimum wage increases, paid leave requirements, or workplace safety mandates � Justworks notifies you and provides guidance on required changes to your policies and practices.

Workers' compensation insurance is included in all Justworks plans and administered through the PEO. This means you do not need to find your own workers' comp carrier, manage annual audits, or handle claims administration. Justworks pools workers' compensation across its client base, which often results in more favorable rates than small businesses could obtain independently, especially in higher-risk industries.

Employment practices liability coverage helps protect your company against claims of wrongful termination, discrimination, harassment, and other employment-related lawsuits. While this does not replace independent employment practices liability insurance, it provides an additional layer of protection through the PEO relationship.

Justworks earns an 8.7 out of 10 Softora score because it delivers on the core PEO promise � giving small businesses access to enterprise-quality benefits, automated payroll, and compliance support through a transparent, well-designed platform. The published per-employee pricing eliminates the fee opacity that plagues many PEO providers, and the employee experience is genuinely consumer-grade in its simplicity.

The main limitations are the absence of international support, the lack of strategic HR features like performance management and engagement tools, the inherent complexity of co-employment for certain business contexts, and the per-employee cost that becomes significant at scale. Companies that need international hiring, advanced HR capabilities, or complete control over their employment structure should look at alternatives like Gusto, Rippling, or Deel.

Start with the Plus plan to take full advantage of the PEO benefits model. If enterprise-quality health insurance and hands-on compliance support are valuable to your team, Justworks likely provides more value than managing these functions independently. If your company is under ten employees and primarily needs payroll with basic benefits, Gusto may be a more cost-effective starting point.
