Gusto vs OnPay: Which Payroll App Actually Saves Small Businesses Money

Fact-checked by the ZeroinDaily editorial team

Updated July 2026

Mark, who runs a small landscaping business in Ohio, was losing sleep over payroll taxes. He had five employees, one in another state, and his spreadsheet kept spitting out different numbers than the IRS expected. After a $1,200 penalty for a misclassified worker, he started looking for an app that could get it right without costing him a fortune.

He is far from alone. Small businesses pay 39% of all private‑sector payroll in the U.S., a total of $3.47 trillion according to the U.S. Small Business Administration. The average payroll error rate is 1.2% each pay period, and nearly 40% of small and medium‑sized businesses end up fined by the IRS for payroll tax deposit, calculation, or filing slip‑ups. The right payroll app is not just a convenience; it is a financial shield.

Two names come up constantly: Gusto and OnPay. They are both full‑service cloud payroll platforms that handle tax filings, direct deposit, and compliance. But beneath the surface, their pricing and feature packaging pull small business owners in very different directions. This comparison dissects the real math so you can pick the one that keeps more cash in your account.

The Real Cost of Payroll Mistakes

Mark’s $1,200 penalty is mild by IRS standards. The IRS assesses failure‑to‑deposit penalties of 2% to 15% of the underpayment, plus interest. For an S‑corporation with 10 employees and a quarterly payroll of $150,000, a filing error can easily trigger a four‑figure fine. Payroll apps promise to stop these mistakes by automating wage calculations, tax withholding, and reporting. But which one actually follows through cheaper?

Everyone talks about monthly subscription prices, but the real expense is what you pay for errors a platform does not prevent. OnPay covers all federal, state, and local tax filings within its base price, including year‑end W‑2 and 1099 forms. Gusto does too on the Simple plan, but only for a single state. Add a second state, and you must jump to the Plus tier, which more than doubles the base fee and per‑employee cost. That alone makes OnPay the cheaper compliance partner for any business with even one remote worker.

Behavioral economists point to a phenomenon called “the flat‑rate bias.” People overpay for subscriptions that feel predictable even when a per‑use or simpler‑looking fee would be cheaper. OnPay exploits that bias in your favor by giving you everything for one price. Gusto exploits it the other way: the low starter price looks appealing, but the true cost only emerges later when you upgrade.

Gusto vs OnPay: Pricing Showdown

Let’s lay the numbers side by side. OnPay charges a flat $40 monthly base fee plus $6 per person, with no hidden add‑ons. Gusto’s pricing is tiered:

• Simple: $49/month + $6 per person. Single‑state only, basic reports, no time tracking or next‑day direct deposit.
• Plus: $80/month + $12 per person. Multi‑state, time tracking, project tracking, and deeper HR features.
• Premium: Custom pricing for dedicated support and advanced compliance.

For a single‑state business with 10 employees, the math is straightforward:

A $9 difference doesn’t sound dramatic. But multi‑state transforms the picture. OnPay’s $100 price stays the same. Gusto Simple cannot handle multi‑state at all; you must select the Plus plan:

That’s $1,200 more per year, cash you could invest in a new piece of equipment or put toward your own retirement. The gap grows even larger when you add time tracking, since Gusto requires Plus for that feature while OnPay bakes it into the base.

For very small teams, the gap is narrower. A three‑employee single‑state company pays $58 with OnPay ($40 + $18) and $67 with Gusto Simple ($49 + $18). Still a slight edge, but not the deciding factor.

What Each Plan Delivers and Where You Pay Extra

Pricing only tells half the story. Mark’s situation required time tracking for his landscaping crews, multi‑state tax registration for his Ohio and Pennsylvania workers, and the ability to run off‑cycle bonus checks without paying a penalty. OnPay’s all‑in‑one approach gave him those tools immediately. Gusto would have forced him into at least the $200/month Plus tier to unlock time tracking and multi‑state support.

Here is where the two platforms diverge on core features:

• Payroll runs: Both offer unlimited payroll runs. No difference.
• Direct deposit: Both support next‑day or two‑day; Gusto’s Simple plan requires a two‑day deposit unless you pay for expedited processing.
• Tax filing: OnPay handles all federal, state, and local filings regardless of location. Gusto handles them for the states you select in your plan; the Simple plan covers one state only.
• Year‑end forms (W‑2, 1099): Included in both, but OnPay e‑files them at no extra charge even for large volumes.
• Time tracking: Free with OnPay; Gusto requires the Plus plan ($80 base).
• HR resource library and compliance alerts: OnPay includes basic HR document templates and a compliance library. Gusto’s Plus tier adds more robust HR tools like employee handbooks and on‑boarding checklists.
• Integration with accounting software: Both integrate with QuickBooks, Xero, and other platforms. Gusto’s integrations are deeper and more polished, a genuine advantage for firms already running QuickBooks Online or ADP for benefits.
• Employee self‑service portal: Gusto’s portal is more modern, with a highly rated mobile app. OnPay’s portal is functional but less sleek.

ADP and Paychex, the legacy giants, bundle similar features but typically cost far more for small companies, often starting above $100 per month plus per‑employee fees that get murky fast. Next to those, both Gusto and OnPay are a bargain. But between the two, OnPay’s features‑per‑dollar ratio wins for the under‑20 crowd.

Multi‑State Payroll Without the Upgrade Fees

Remote work reshuffled small business geography. If your company has even one employee in a different state, you are a multi‑state employer in the eyes of the IRS and must comply with each state’s unemployment insurance, withholding rules, and reporting deadlines. A business that hires a marketing contractor in Texas while based in Arizona triggers multi‑state obligations.

OnPay was built from the start to handle multi‑state payroll with no premium. You register with the new state’s agencies, add the employee, and the system applies the correct tax rates automatically. Gusto’s multi‑state feature works well, but the cost barrier is real: you skip past the Simple plan directly to Plus. For a five‑person team with two states, that’s OnPay’s $70/month versus Gusto Plus’s $140/month. Over a year, OnPay saves $840.

A digital marketing agency with 8 employees, spread across California, Texas, and New York, runs a monthly payroll of about $52,000. OnPay charges them $40 base plus $6 per person, totaling $88/month. Gusto would require the Plus plan at $80 base and $12 per person, coming to $176/month. That saves the agency $1,056 per year, enough for a new laptop or a modest advertising push.

Industry data supports just how prevalent the multi‑state challenge has become. The SBA reports that the number of small firms with remote workers grew sharply after 2020, and state tax agencies have only stepped up enforcement. Platforms that nickel‑and‑dime this need are costing business owners real money.

When Gusto Is the Better Choice

It would be misleading to present OnPay as universally superior. Gusto earns its higher price tag in several specific scenarios. The crossover point where Gusto’s bundled HR and benefits start to justify the extra cost is around 25 employees. Below that, OnPay’s all-in pricing typically wins; above it, the value of integrated health insurance and 401(k) setup can tip the scales.

First, businesses with more than 50 employees often outgrow OnPay’s HR toolkit. Gusto’s Plus and Premium plans offer full employee handbooks, performance review templates, and compliance alerts that can replace a dedicated HR staffer. Gusto also provides a benefits brokerage where you can set up health insurance, 401(k) plans, and commuter benefits through one dashboard, something OnPay can do but often requires third‑party partnerships.

Second, Gusto integrates more tightly with QuickBooks Online, Xero, and Square. If your accountant lives inside QuickBooks and you want every payroll journal entry to map perfectly, Gusto’s sync is nearly seamless. OnPay’s integration works, but users report occasional mapping glitches with class tracking.

Third, Gusto’s employee‑facing experience is genuinely polished. The mobile app, digital pay stubs, and self‑onboarding flows get high marks in reviews from Forbes Advisor and NerdWallet. If you want your team to feel like they work at a tech‑forward company, which can matter for retention, Gusto delivers that experience better.

Fourth, OnPay lacks a native mobile app. For businesses with hourly workers who check pay stubs from their phones, the mobile‑responsive site can be clunky. Gusto’s app is smooth and often reduces the number of payroll questions managers field. If you have a mobile‑first workforce, this alone may justify Gusto’s higher price, even for teams under 25 employees.

The tradeoff is that you pay a premium for the polish. For small businesses without an HR department, Gusto’s bundled HR support can actually be a cost‑effective alternative to hiring a part‑time consultant. So the calculation shifts once your headcount passes a threshold. Evaluate whether you need streamlined compliance (OnPay wins) or a light‑touch HR department in a box (Gusto wins).

Hidden Fees and Long‑Term Value

Both platforms are straightforward about what you pay, but fine print exists. OnPay does not charge setup fees, cancellation fees, or extra for filing year‑end forms. Gusto likewise avoids hidden fees on the core plans; however, some add‑ons, like full‑service state tax registration for new jurisdictions, can incur one‑time fees if you need them handled manually. Call it the “we’ll do it for you” surcharge.

Check for contract terms. Both companies operate month‑to‑month with no long‑term lock‑in, which is crucial for seasonal businesses like Mark’s landscaping firm. He ramps up in spring, adds employees, and winds down in winter. OnPay’s per‑person billing makes it simple to scale up and down without paying for idle seats. Gusto calculates charges similarly, so no meaningful difference there.

Over five years, the cumulative savings with OnPay for a ten‑person multi‑state business can exceed $6,000, assuming no rate changes. That sum could fund a new truck, a marketing campaign, or simply sit in a high‑yield business savings account at a bank like Chase or an online institution such as SoFi earning interest. When framed that way, the choice is clearer.

How We Evaluated

We built pricing models for teams of 3, 10, 20, and 50 employees across single‑state and multi‑state configurations. We used publicly available rate cards from OnPay and Gusto, verified against Forbes Advisor and NerdWallet reviews. Payroll error risk calculations drew from the Bureau of Labor Statistics data compiled by the National Association of Women Business Owners and from the Internal Revenue Service. Total small business payroll figures came from the U.S. Small Business Administration. We did not rely on company‑provided marketing materials alone; every claim was cross‑checked against at least two independent sources.

We also considered the role of the Consumer Financial Protection Bureau (CFPB) and Federal Reserve in shaping payment and employment regulations, though they do not directly oversee payroll apps. Their oversight of paycheck protection and small business lending underscores the compliance ecosystem that these apps navigate.

Frequently Asked Questions

Is OnPay really cheaper than Gusto for all small businesses?

For companies with fewer than 20 employees and single‑state needs, OnPay is almost always cheaper. The difference is modest ($9/month for 10 employees single‑state) but grows to $100/month or more when you need multi‑state filing. For firms with 50+ employees, Gusto’s bundled HR tools can offset its higher subscription cost.

What does OnPay include that Gusto charges extra for?

Multi‑state payroll, time tracking, next‑day direct deposit, and a basic HR library are all part of OnPay’s $40 base. Gusto requires at least the $80 Plus plan to unlock time tracking and multi‑state support, and its Simple plan lacks next‑day deposit unless you pay an additional fee.

Can Gusto handle payroll in all 50 states?

Yes, Gusto can file taxes in every state and the District of Columbia, but you must be on the Plus plan or higher. The Simple plan limits you to one state.

Which app is better for a business with mostly 1099 contractors?

Both handle 1099 workers equally well and allow unlimited contractor payments. If contractors are the bulk of your workforce, the price gap shrinks because per‑employee fees for 1099 workers are often the same or lower. OnPay’s lower base still gives it a slight edge.

Does OnPay integrate with QuickBooks and other accounting tools?

Yes, OnPay integrates with QuickBooks Online, Xero, and several other platforms. The integration is solid, though some accountants report that Gusto’s QuickBooks sync is more polished and requires less manual cleanup.

What happens if a payroll mistake occurs, does either service cover penalties?

Both providers file taxes on your behalf and assume responsibility for errors they cause. If a tax notice arises from a mistake the platform made, Gusto and OnPay will work with the taxing agency and typically cover the penalty and interest. You must provide accurate data; mistakes due to your own mis‑classification or incorrect hours are not covered.

How is customer support? Which has better help?

OnPay offers phone, email, and chat support included in the base price, with no extra charge. Gusto provides phone support on the Plus and Premium plans; Simple plan users can access email and chat. Third‑party reviews generally rate Gusto’s support slightly higher for responsiveness, but OnPay’s team is known for deep payroll knowledge. Both are far ahead of the industry giants ADP and Paychex for small‑business support experience.

Can I switch from Gusto to OnPay mid‑year without messing up my taxes?

Yes, you can switch payroll providers at any time. The new provider typically imports your year‑to‑date payroll data so tax forms remain accurate. OnPay offers migration assistance at no extra charge. It’s best to transition at the start of a quarter to avoid mid‑quarter filing complexity.

Does either platform offer a mobile app for employees?

Gusto has a highly rated mobile app where employees can view pay stubs, update W‑4s, and request time off. OnPay provides a mobile‑responsive website but does not have a native app, which may be a drawback for teams that live on their phones.

Is Gusto worth the higher cost for a company with 10 employees?

If you operate in a single state, do not need built‑in time tracking, and value a polished employee portal, Gusto Simple at $109/month may be worth the extra $9 over OnPay. But if you plan to add workers across state lines or want to avoid upgrade fees when your needs change, OnPay’s all‑in pricing is safer.
