PEO Companies in New York: 7 Compared

If you run a business in New York City, Long Island, or anywhere upstate and are shopping for a professional employer organization (PEO), most of what you find online is written by companies that sell PEO or broker services. I build HR software for small businesses and the people who run their HR, and I think the PEO decision deserves straight answers instead.

This guide answers the two questions that decide the purchase: what co-employment actually costs at your headcount, and whether your business needs a PEO at all or would be better served by simpler HR software. New York's heavy compliance load makes that second question especially worth asking honestly.

Along the way, the guide compares seven PEO companies that genuinely serve New York, does the cost math on both pricing models, and walks through the state and city compliance a PEO handles, from Paid Family Leave to NYC's sick-leave rules to pay transparency.

Every price and requirement here was verified in October 2026; confirm current terms on each vendor site and with the New York Department of Labor, since pricing and rules change. Where a provider does not publish rates, we say so rather than inventing a number. FirstHR is our product, and it is HR software, not a PEO, so we place it only where it genuinely fits and route you to a PEO where that is what you actually need.

What a PEO is

A PEO, or professional employer organization, enters a co-employment arrangement with your business. Your employees keep working for you day to day, but the PEO becomes the employer of record for tax and benefits purposes under its own federal tax ID: it runs payroll, sponsors benefits, carries workers' compensation, and handles much of HR compliance. In exchange, a small business gains access to pooled health benefits and workers' compensation rates it could not get alone.

That shared-responsibility model is the whole point, and also the tradeoff. You gain benefits buying power, a master workers' compensation policy, and offloaded administration, but you give up some control and take on a per-employee or percentage-of-payroll cost. Whether the trade is worth it depends on your size, your benefits needs, and how much compliance weight your state puts on you, which in New York is considerable.

Why New York businesses consider a PEO

New York businesses turn to PEOs for two main reasons: benefits and workers' compensation access, and relief from one of the heaviest compliance loads in the country. Because a PEO pools your employees with thousands of others, it can offer health, dental, and retirement benefits at large-group rates and place your workers under a master workers' compensation policy, which a small New York employer cannot replicate alone.

The compliance value is unusually high in New York. A PEO helps administer Paid Family Leave, mandatory disability and workers' compensation, pay-transparency obligations, and, for New York City employers, the Earned Safe and Sick Time Act, alongside payroll tax filing and new hire reporting.

For a company hiring across multiple states, the strongest reason of all is often multi-state payroll and the compliance handling that comes with it. New York also regulates PEOs under the New York Professional Employer Act, so a registered provider carries a state credential you can verify.

PEO companies serving New York

Every major national PEO serves New York, and the state also has notable home-grown providers, including Manhattan-headquartered Justworks and Long Island's PrestigePEO. The table below covers the seven providers most relevant to a New York small business, with pricing model, minimum size, and certification, followed by an honest look at each.

The certification column uses two abbreviations. CPEO marks a provider the IRS has certified as a Certified Professional Employer Organization, and ESAC marks accreditation by the Employer Services Assurance Corporation.

Justworks is headquartered in Manhattan and is the transparency choice in a market where almost everyone quotes privately. It publishes flat per-employee-per-month (PEPM) rates, Basic at $79 and Plus at $124, so a New York business can budget without a sales call.

Justworks runs a technology-first platform that handles payroll, compliance, and benefits administration cleanly, and its CPEO status and ESAC accreditation give it strong trust credentials for co-employment. For a New York startup or small business that values a predictable number and self-serve setup, it is the easiest PEO to evaluate.

TriNet, a publicly traded PEO founded in 1988, leans toward venture-backed startups and companies in technology, financial services, and life sciences, with industry-tailored HR bundles and strong HR advisory. For a growing New York company that wants service depth and vertical expertise rather than the lowest price, TriNet is a leading option.

TriNet prices its service as a quoted flat fee per employee per month, never a percentage of payroll. It works with businesses of 5 to more than 1,000 employees, and a very small team may find it heavier than it needs.

ADP describes TotalSource as the largest IRS-certified and ESAC-accredited PEO in the country, and its fiscal 2026 annual report counts more than 19,000 clients and 770,000 worksite employees. TotalSource is backed by ADP's deep payroll infrastructure and broad benefits buying power. For a New York employer that is multi-state, larger, or already inside the ADP ecosystem, it offers bundling advantages and payroll depth few can match.

Every TotalSource client works with a dedicated HR business partner, and the service is built for businesses of 5 to more than 1,000 employees. Pricing is quoted rather than listed, based on headcount, payroll, locations, industry, and benefits needs, so ask for the full fee schedule before signing.

Insperity sits at the premium, high-service end of the PEO market, with sales and service operations across the United States. Its 2026 fact sheet puts its target market at businesses of 5 to 5,000 employees.

For an established New York small or mid-size business that wants a hands-on HR relationship and is willing to pay for it, Insperity is a top choice. Its fee is a markup computed as a percentage of payroll, so it rises with wages, and the value depends on how much you use its full-service HR support.

Paychex runs dual headquarters in Rochester, New York, and Cincinnati, Ohio, and is one of the most established payroll and HR names in the country. Its PEO, which includes the Paychex Oasis line, brings that scale and a wide New York service footprint. It suits an owner who wants a large, recognizable provider with payroll heritage and broad benefits access.

Paychex PEO pricing is quote-based, and support scales with headcount: clients with fewer than 10 employees work with an assigned HR business partner, a client advocate is available at 10 or more, and a relationship manager is assigned at 200 or more.

PrestigePEO is based in Melville on Long Island and has served New York small businesses since 1998, when insurance brokers founded it. It now operates as a full-service PEO with a strong benefits focus, describes itself as a PEO founded by brokers, for brokers, and pays commissions to the broker partners who bring it clients.

For a New York or Long Island employer that wants a local provider deeply familiar with New York's compliance rules and benefits market, PrestigePEO is a relevant regional option. It holds IRS CPEO certification and ESAC accreditation, and pricing is quote-based.

ExtensisHR focuses squarely on small and mid-size businesses (SMBs) from its base in Iselin, New Jersey, and since a 2025 expansion westward it serves customers nationwide. That focus makes it a relevant option for a New York employer that wants a PEO built around SMB needs rather than one that treats small clients as an afterthought.

ExtensisHR has held ESAC accreditation since 2008 and CPEO status since 2017, solid credentials for a co-employment relationship. Pricing is quote-based, so request an itemized breakdown to compare it against Justworks, the one provider here with published rates.

What a PEO costs as your team grows

PEO pricing follows one of two models: a flat per-employee-per-month fee or a percentage of total payroll. According to the U.S. Chamber of Commerce (March 2026), small businesses typically pay $40 to $200 per employee per month under the first model or 2 to 12 percent of gross payroll under the second.

The percentage model scales with wages, so a higher-paid New York workforce costs more under it, while the flat model is more predictable. The table below shows administrative-fee cost only at three headcounts, using $100 per employee per month and 5 percent of payroll as illustrative rates.

Two things matter when reading these numbers. First, the administrative fee is only part of the bill: benefits premiums and workers' compensation pass through separately, and setup fees and possible termination penalties sit on top, so full co-employment cost runs well above the admin fee.

Second, providers quote differently, so you can only compare them fairly when each quote lists the admin fee separately from pass-through insurance. Justworks publishes flat rates, which makes it a useful anchor; TriNet, ADP, Insperity, Paychex, PrestigePEO, and ExtensisHR quote privately.

New York compliance a PEO handles

The main New York obligations a PEO handles are Paid Family Leave, workers' compensation and disability, pay transparency, and, in New York City, expanded safe and sick leave. New York layers these state and city obligations more heavily than most states, and understanding them helps you judge how much value co-employment actually adds.

Beyond those, the New York State pay transparency law, Labor Law 194-b, and the New York City salary transparency rule both cover employers with four or more employees. Both require good-faith salary ranges in job postings, and New York City can impose civil penalties of up to $250,000 for an uncured violation, meaning one the employer fails to correct in time.

The New York WARN Act, which requires advance notice of plant closings, mass layoffs, and other covered cutbacks, is stricter than the federal version: it applies at 50 or more full-time employees and calls for 90 days of notice. Workers' compensation and disability insurance are mandatory as well.

A PEO administers these deductions, filings, and policies, and can place your workers under its master workers' compensation policy, which is a real advantage HR software cannot replicate. The tradeoff is that you take on co-employment and its cost to get it.

PEO vs HR software: which do you need?

The answer turns on whether you actually need co-employment. Many businesses shopping for a New York PEO really want to offload onboarding, documents, e-signature, compliance workflows, and employee records, not to hand an outside firm shared legal responsibility for their workforce and pay per-employee co-employment fees for it.

The National Association of Professional Employer Organizations (NAPEO) found in its 2025 client research that 35 percent of PEO clients have fewer than 10 employees and half have 10 to 49, so most PEO users have fewer than 50. That puts a small New York business right at this decision point.

A New York business primarily needs a PEO when it wants pooled health benefits it cannot get alone, workers' compensation under a master policy, or full co-employment liability transfer. If the real pain is running HR well in-house (onboarding, records, document management with e-signature, and compliance workflows), that is an HR software problem, not a co-employment problem.

The honest split is this: when benefits pooling, master-policy workers' compensation, or co-employment liability transfer is the goal, a PEO earns its fee, and New York's compliance load makes that case real for many employers.

If the goal is simply to stop drowning in onboarding paperwork and scattered records, and you do not yet need group benefits pooling, HR software handles that, keeps you in control, and costs far less. A small New York business under about 10 employees with no benefits-pooling need often does not need a PEO yet.

How to choose a PEO in New York

Choosing a PEO in New York comes down to five questions, from state registration and IRS certification to whether you need co-employment at all. Work through all five before you sign anything.

Frequently Asked Questions

What is a PEO?

A PEO, or professional employer organization, enters a co-employment arrangement with your business. Your employees keep working for you, but the PEO becomes the employer of record for tax and benefits purposes under its own federal tax ID, running payroll, sponsoring benefits, carrying workers' compensation, and handling much of HR compliance. In exchange for a per-employee fee or a percentage of payroll, a small business gains access to pooled benefits and workers' compensation rates. Co-employment means shared legal responsibility, the core distinction from HR software, which you operate as the sole employer.

How much do PEO companies cost in New York?

Small businesses typically pay a PEO 2 to 12 percent of gross payroll or $40 to $200 per employee per month, according to the U.S. Chamber of Commerce (March 2026), with benefits and workers' compensation passing through on top. At $100 per employee per month, the admin fee alone for a 25-person NY company runs around $30,000 a year. Of the providers here, only Justworks publishes rates (Basic $79, Plus $124 per employee); the rest quote privately, so ask for an itemized quote that lists the admin fee apart from pass-through costs.

Do PEOs have to register in New York?

Yes. New York regulates PEOs under the New York Professional Employer Act: a PEO must register with the New York State Department of Labor and renew annually unless it qualifies for an exemption. Before signing, confirm the PEO is registered in New York and, ideally, holds IRS Certified PEO status, which limits your tax liability if the PEO fails to remit employment taxes. Both are real trust signals in a relationship where the PEO handles your payroll taxes and sponsors benefits under its own tax ID.

What New York compliance does a PEO handle?

A PEO helps with Paid Family Leave (applies to employers with as few as one NY employee); mandatory workers' compensation and disability insurance; state pay transparency under Labor Law 194-b and the city salary transparency rule, both covering employers with four or more employees; and, for NYC employers, the Earned Safe and Sick Time Act. It also handles payroll tax filing and new hire reporting. A PEO can place your employees under its master workers' compensation policy, one of the clearest advantages it offers over HR software in a high-regulation state like New York.

What is New York's current Paid Family Leave requirement?

New York Paid Family Leave applies to private employers with at least one employee working in New York. For 2026, the employee contribution rate is 0.432 percent of gross wages per pay period, up from 0.388 percent in 2025, capped at $411.91 a year. Eligible employees can take up to 12 weeks of job-protected leave at 67 percent of average weekly wage, with a maximum weekly benefit of $1,228.53 in 2026. A PEO administers these deductions and filings, though an employer can also handle Paid Family Leave through its own disability carrier.

Do I need a PEO or is HR software enough for my NY business?

It depends on what you need. A PEO makes sense for pooled health benefits, workers' compensation under a master policy, or transferring employer legal responsibility through co-employment, with a per-employee fee and shared control. If your real need is onboarding, document management, e-signature, an employee database, and compliance workflows without giving up control, HR software covers that at a fraction of the cost. NAPEO's client research shows most PEO users have fewer than 50 employees, which puts small NY businesses right at this decision point. A business under about 10 employees with no benefits-pooling need is often better served by software.

Are there PEO companies based in New York?

Yes. Justworks is headquartered in Manhattan and publishes its pricing. PrestigePEO, in Melville on Long Island, is a certified PEO founded by insurance brokers that still works with broker partners. Alcott HR is a Long Island CPEO, and KEENA PEO Services serves upstate New York. National providers such as TriNet, ADP TotalSource, Insperity, and Paychex serve New York statewide, from NYC through Buffalo, Rochester, Albany, and Long Island. Confirm any provider is registered with the New York Department of Labor and whether it is the actual PEO or a broker.
