About Justworks

Justworks is a New York-based IRS CPEO certified and ESAC accredited Professional Employer Organization founded in 2012. Built for the modern workforce, Justworks combines co-employment with a clean, tech-first platform that lets small and mid-sized businesses manage payroll, benefits, compliance, and HR from one intuitive dashboard. In 2025, Justworks processed over $31 billion in payroll, filed $8.9 billion in employer taxes, and generated more than 268,000 W-2s for its PEO clients. Justworks offers two transparent PEO pricing tiers: Basic at $79 per employee per month (payroll, compliance, workers compensation, 401k) and Plus at $109 per employee per month, which adds medical, dental, and vision benefits administration. Unlike most legacy PEOs, Justworks publishes its pricing openly with no hidden fees. The platform supports all 50 states and over 4,000 tax localities, making multi-state hiring straightforward. Justworks is best known for giving 5-person startups access to the same United Healthcare, Aetna, and Kaiser Permanente health plans as large corporations. The company also offers international EOR services in 17 countries and contractor payments in 50+ more, making it a natural fit for remote-first and globally distributed teams.

IRS Certification

IRS Certified PEO (CPEO)
Certification active · Verified by PEO Authority
Certified ✓

The IRS Certified PEO (CPEO) designation is awarded by the Internal Revenue Service to PEO companies that meet rigorous standards for financial health, tax compliance, and operational integrity. Justworks holds CPEO status — a distinction held by fewer than 15% of PEOs in the United States.

Federal Tax Liability
As a CPEO, Justworks assumes sole liability for federal employment taxes on wages paid — protecting your business from tax exposure.
Annual Financial Audits
CPEOs undergo independent CPA audits annually and must maintain a surety bond, ensuring fiscal accountability and solvency.
IRS Reporting
Justworks files employment taxes under their own EIN as CPEO, simplifying your year-end tax obligations and eliminating duplicate filings.

PEO Authority Editorial Note

Justworks earns its position as one of the most-searched PEO brands by delivering on a simple promise: make HR as easy as possible for small businesses. Its transparent pricing is genuinely rare in an industry notorious for opaque quotes. The main caveat is scale — at 150+ employees, costs begin to rival a dedicated in-house HR operation. Best for: tech startups, professional services firms, and remote-first companies with 5-150 employees that want modern software and predictable monthly costs.
