Does Gusto offer PEO services?

No. Gusto is payroll and HR software, not a PEO. Your company remains the sole employer of record when using Gusto. Gusto previously had a PEO partnership offering but discontinued it. Gusto's health insurance comes through a broker network on small-group terms, not large-group PEO rates.

What does co-employment mean for my business?

Co-employment means Justworks and your company share the legal employer role for your employees. Justworks files payroll taxes as the employer of record, carries workers compensation under a master policy, and provides access to its large-group insurance pool. Your company retains control over hiring, firing, job duties, and pay rates. Co-employment is a formal legal arrangement, not just an outsourcing agreement.

Is Justworks PEO worth the extra cost compared to Gusto?

It depends entirely on your health insurance situation. If the savings from Justworks's large-group health insurance rates exceed $79/employee/month compared to what you pay on the small-group market, the PEO fee pays for itself. If you do not offer health insurance or already have a competitive group rate, Gusto is almost certainly cheaper for the same payroll functionality. Request a side-by-side insurance quote before deciding.

Which is better for employees in multiple states?

Both handle multi-state payroll without a surcharge. Gusto includes all-50-state tax filing in every plan tier. Justworks PEO handles multi-state compliance through the co-employment structure. The difference is liability: with Justworks CPEO, Justworks is legally responsible for multi-state payroll tax filings. With Gusto, your company remains responsible. For businesses with employees in many states where compliance complexity is high, the CPEO liability shield has practical value.

Can I switch from Gusto to Justworks (or vice versa)?

Yes, but plan for a full payroll transition. Switching mid-year requires reconciling year-to-date payroll data and W-2 reporting. Gusto exports data in standard formats. Justworks typically requires a 30-day implementation period for PEO onboarding, including benefits enrollment for your employees. Most businesses switch at the start of a calendar quarter to simplify tax reporting.

What is the minimum number of employees for Justworks PEO?

Justworks PEO starts at 2 employees with no formal minimum listed for the PEO product. In practice, the $79/PEPM fee is hard to justify for 2 to 4 employees unless health insurance savings are significant. Most businesses find the Justworks PEO value proposition strongest in the 10 to 50 employee range.

Justworks vs Gusto 2026: Not the Same Product (Read This Before Choosing)

Last updated: September 2026

TL;DR

For teams under 10 employees: Gusto Simple ($49/month + $6/employee) is almost always the right call. It costs a fraction of Justworks PEO ($79/employee/month) and handles payroll, benefits, and compliance well. For teams of 10 to 50 employees where health insurance is a major cost: Justworks PEO can pay for itself if its large-group insurance rates save more than $79/employee/month compared to your current small-group premiums. The fundamental issue: Gusto and Justworks are not the same type of product. Gusto is payroll software. Justworks PEO is a co-employment arrangement. Comparing them only on price misses the point.

ℹ Gusto is not a PEO. Justworks is not just payroll software.

When you use Gusto, your company remains the sole legal employer. When you use Justworks PEO, Justworks becomes your co-employer, takes on legal responsibility for payroll taxes, provides access to its group insurance pool, and shares compliance liability. These are fundamentally different arrangements with different cost structures and different risks.

The Core Difference: Payroll Software vs Co-Employment

Gusto processes your payroll. It calculates taxes, files federal and state returns, handles direct deposit, and gives employees self-service access to their paystubs. You remain the employer of record. You manage HR decisions. You buy health insurance through Gusto's broker network (small-group rates).

Justworks PEO does something structurally different: it becomes your co-employer. Your employees are legally employed by both your company and Justworks simultaneously. This is what enables Justworks to pool thousands of small-business employees into a single large group for insurance purposes, giving a 10-person team access to health insurance pricing that normally requires 500+ employees. It also means Justworks carries the legal liability for payroll tax compliance.

✓ Justworks also has a Payroll-only product most comparisons ignore

Justworks Payroll ($8/employee/month + $50 base) is a straight payroll software product with no co-employment, no PEO. At 10 employees it costs $130/month, which makes it directly comparable to Gusto Simple at $109/month. Most 'Justworks vs Gusto' articles only compare Justworks PEO to Gusto, which is misleading. If you want Justworks without the PEO structure, the Payroll plan is available.

Real Cost Comparison at Every Team Size

Monthly software cost only (excludes health insurance premiums), prices verified September 2026.

Team size	Gusto Simple	Gusto Plus	Justworks Payroll	Justworks PEO Basic	Justworks PEO Plus
5 employees	$79/mo	$140/mo	$90/mo	$395/mo	$620/mo
10 employees	$109/mo	$200/mo	$130/mo	$790/mo	$1,240/mo
25 employees	$199/mo	$380/mo	$250/mo	$1,975/mo	$3,100/mo
50 employees	$349/mo	$680/mo	$450/mo	$3,950/mo	$6,200/mo

At face value, Justworks PEO Basic costs 7x more than Gusto Simple for a 10-person team ($790 vs $109/month). That number is the reason most small businesses stop reading and choose Gusto. But the software cost alone is not the right comparison if health insurance is in the picture.

When Justworks PEO Pays for Itself: The Health Insurance Math

The business case for Justworks PEO rests almost entirely on health insurance. When your company joins Justworks, your employees enter Justworks's large-group insurance pool, which covers tens of thousands of people. Large-group plans are priced differently than small-group plans: the insurance carrier spreads risk across a much bigger population, which lowers premiums.

Health insurance premiums vary widely by state, age mix, and plan tier, so no single number applies universally. The principle: if the savings on each employee's monthly premium exceed $79, the Justworks PEO Basic fee pays for itself and your total HR cost is the same or lower than Gusto plus small-group insurance. Industry estimates place the potential premium reduction at 15 to 30 percent for employers switching from a small-group policy to a large-group PEO pool.

⚠ Run your own numbers with your current insurance broker

Do not take any published estimate as your actual savings. Request a side-by-side quote: your current small-group premium per employee vs the Justworks large-group rate for the same tier and state. If the gap exceeds $79/employee/month, Justworks PEO Basic costs less than Gusto plus your current insurance. If the gap is under $79, Gusto is cheaper.

There is one scenario where the math almost always works: companies with older employees or employees in high-cost states (California, New York, New Jersey) where small-group premiums are especially steep. There is one scenario where it almost never works: very small teams (2 to 4 employees) where the absolute dollar amount of the PEPM fee exceeds any realistic insurance savings.

Payroll Processing and Multi-State Compliance

Both platforms handle federal 941 and 940 filings, state unemployment insurance, W-2 and 1099-NEC generation, and direct deposit. Both support employees in all 50 states without an additional multi-state fee (Gusto includes multi-state payroll in all plan tiers, not just Plus as some sources still claim based on older pricing).

The compliance difference comes from the legal structure. With Justworks PEO, the IRS-certified PEO (CPEO) designation means Justworks carries legal responsibility for payroll tax deposits and filings. If there is a calculation error or a missed filing deadline, that liability sits with Justworks. With Gusto, it sits with you. For most small businesses this distinction is theoretical since Gusto's error rate is low, but for founders who want to offload compliance risk entirely, the CPEO certification has real value.

Integrations and Software Ecosystem

Gusto connects to over 150 third-party tools including QuickBooks Online, Xero, FreshBooks, Salesforce, Google Workspace, Microsoft 365, Slack, Expensify, and most major applicant tracking systems. It also has a Gusto MCP integration for AI assistants (Claude, ChatGPT, Gemini). The integration ecosystem is a genuine strength.

Justworks integrates with major accounting platforms (QuickBooks, Xero) and a smaller set of HR and project management tools. The PEO model limits some integration flexibility because Justworks owns the employer-of-record layer. If your business depends on a specific payroll integration, verify it exists in Justworks before switching.

Customer Support

Justworks offers 24/7 support via phone, email, chat, and Slack for all PEO customers. Dedicated account managers are assigned to PEO accounts. This is a meaningful operational advantage for companies that run payroll on irregular schedules or have compliance questions outside business hours.

Gusto Simple and Plus offer phone and chat support Monday through Friday during business hours. Premium plan customers get priority support and a dedicated HR advisor. After-hours support is not available on standard plans. This is not a major problem for most small businesses with regular payroll cycles, but it is worth noting if your team spans time zones or if payroll issues tend to surface on Fridays.

Who Should Use Gusto

•Teams under 10 employees where the Justworks PEPM cost is hard to justify on a per-dollar basis
•Businesses that want full control over HR decisions and do not want a co-employment arrangement
•Companies that need more than 150 software integrations or rely on specific tools that Justworks does not support
•Startups wanting a free trial before committing (Gusto lets you run your first payroll before billing starts)
•Businesses with international contractors who prefer Gusto's $6/contractor/month pricing over Justworks's $39/contractor/month
•US-only businesses with straightforward payroll and no benefits complexity

Who Should Use Justworks PEO

•Teams of 10 to 50 employees where health insurance is a significant budget line and large-group rates can offset the $79 PEPM
•Companies in high-cost insurance states (California, New York, New Jersey) where small-group premiums are especially steep
•Founders who want to legally offload payroll tax compliance liability via CPEO co-employment
•Companies that need 24/7 HR support and cannot wait until Monday for compliance questions
•Businesses operating across many states that want a single point of responsibility for multi-state employment law
•Companies planning rapid headcount growth (1 to 50 employees) who want enterprise-grade benefits accessible from day one

What Neither Covers: Global Employees

Justworks PEO is US-only for full-time employees. Gusto is also US-only for W-2 employees but supports contractor payments in 120+ countries at $6/payment to US accounts. Neither is a replacement for a global employer of record (EOR) service if you need to hire full-time employees in other countries. For global hiring, Deel ($499/employee/month EOR), Remote, or Rippling Global are the relevant alternatives.

ℹ Justworks EOR for international full-time employees

Justworks does offer an EOR product ($599/employee/month) for hiring in select countries outside the US. Coverage is narrower than Deel or Remote. If global hiring is part of your plan, verify that Justworks EOR covers your specific countries before choosing it over a dedicated EOR provider.

Frequently Asked Questions

Justworks offers both. Justworks PEO (Basic: $79/PEPM, Plus: $124/PEPM) is a co-employment arrangement where Justworks becomes your legal co-employer and provides large-group health insurance access. Justworks Payroll ($8/PEPM + $50 base) is a separate, lower-cost payroll software product with no co-employment. Most comparisons only discuss the PEO product. If you want Justworks without the PEO structure, the Payroll plan exists.
