Gusto vs OnPay 2026: Which Payroll Should You Use?

Why this comparison matters

Gusto and OnPay are the two most frequently compared payroll tools in the SMB market, and for good reason. They share an identical base pricing structure ($40/month + $6/employee), cover all 50 states, include automatic tax filing, and target the same market segment: US small businesses that want a cleaner alternative to ADP or Paychex.

The difference is not price, it is which problems each tool solves best. Gusto was built to make payroll simple for any small business; OnPay was built to handle the payroll scenarios that general tools do poorly. Understanding that distinction is the key to choosing correctly.

G2 scores: Gusto 4.6/5 from 11,246 reviews; OnPay 4.8/5 from 408 reviews. OnPay's higher average score from a smaller base suggests extremely satisfied users in a specific segment, consistent with a tool that does a narrow job exceptionally well.

Head-to-head comparison

Choose Gusto when

You need benefits administration. OnPay does not offer a benefits brokerage marketplace. If you want to offer health insurance, dental, vision, FSA, or HSA through your payroll platform, you need Gusto Plus. This is the clearest deciding factor.

You want a broad integration library. Gusto connects to 100+ tools. If your stack includes BambooHR, Carta, Lattice, or niche accounting software, verify Gusto has the integration. OnPay's integration library is much smaller.

Your team is office-based with standard pay structures. Salaried employees, hourly employees with straightforward overtime, no tips, no agricultural pay, Gusto Simple handles this cleanly and the onboarding experience is better than OnPay's.

You want a mobile admin app. Gusto has a well-rated mobile app for running payroll, approving time-off requests, and managing employees on the go. OnPay does not.

Choose OnPay when

You have tipped employees. FICA tip credit calculation, tip credit enforcement, and tip pooling management are built into OnPay at no extra cost. Gusto requires manual workarounds for the same scenarios.

You need same-day direct deposit. OnPay includes same-day ACH in its base price. Getting equivalent timing from Gusto requires the Plus plan at $80/month base, double the cost.

You run a nonprofit. FUTA exemption configuration and department cost centers for grant allocation are native OnPay features. Multiple nonprofit HR managers in G2 reviews specifically switched from Gusto to OnPay for these.

Support quality matters more than feature breadth. OnPay's US-based support consistently out-rates Gusto's in G2 comparisons. If payroll errors need fast resolution, this is a meaningful differentiator.

You run agricultural or multi-rate payroll. Piece-rate pay, seasonal worker payroll, Form 943, and multi-rate overtime blending are all handled natively in OnPay.

The real decision framework

Answer these three questions: (1) Do you have tipped employees, multiple pay rates, nonprofit status, or agricultural workers? → OnPay. (2) Do you need benefits administration or performance reviews in the same tool? → Gusto Plus. (3) Does neither of the above apply and you just need clean, reliable payroll? → Gusto Simple (better UX) or OnPay (better support + same-day deposit) are equally valid, try both free trials and choose based on which interface your admin prefers.

Pricing worked example at 5, 15, and 30 employees

Headline rates hide real cost, so run the math on actual team sizes. Gusto Simple charges a $49/month base plus $6 per person. OnPay uses a flat $40/month base plus $6 per person with no separate tiers - one plan, every feature included. The base-fee gap is where OnPay pulls ahead for small teams.

At 5 employees, Gusto Simple runs $49 + (5 x $6) = $79/month, while OnPay runs $40 + (5 x $6) = $70/month. That $9 monthly difference ($108/year) matters when you are a 5-person shop watching every line item.

At 15 employees, Gusto Simple is $49 + (15 x $6) = $139/month versus OnPay at $40 + (15 x $6) = $130/month. Still a $9/month spread, since both charge the identical $6 per-person rate. The base fee is the only structural difference, so the dollar gap stays flat as you grow.

At 30 employees, Gusto Simple reaches $49 + (30 x $6) = $229/month and OnPay hits $40 + (30 x $6) = $220/month. OnPay stays $9/month cheaper at every size. The catch: many growing teams outgrow Gusto Simple and move to Gusto Plus ($80 base + $12/person) for next-day direct deposit, time tracking, and multi-state payroll at no extra state fee. At 30 employees Gusto Plus jumps to $80 + (30 x $12) = $440/month - double OnPay. OnPay's flat model wins on raw price; you pay Gusto's premium for the deeper feature set described below.

Bottom line: if cost is the deciding factor and you need standard W-2 payroll, OnPay is consistently cheaper. Gusto's price climbs once you need Plus-tier features, so confirm which tier you actually require before comparing.

Benefits and HR depth: Gusto's advantage

Both providers broker health insurance and run benefits deductions, but Gusto offers materially more HR surface area, which is why it scores 4.5/5 on G2 with a heavy small-business following. Gusto operates as a licensed health insurance broker in 39 states, letting you shop medical, dental, and vision plans directly inside the payroll dashboard with deductions syncing automatically. OnPay also brokers health, dental, and vision in all 50 states, but its plan-shopping and administration experience is thinner.

Where Gusto separates itself is the financial and HR add-on stack: integrated 401(k) through Guideline, workers' comp via pay-as-you-go billing, FSA/HSA/commuter benefits, 529 college savings, and Gusto Wallet with employee savings accounts and on-demand pay (Cashout). For a team that wants to offer a modern benefits package without bolting on five separate vendors, Gusto consolidates it.

On the pure-HR side, Gusto Plus and Premium tiers add an employee directory, org charts, PTO policies with approvals, time tracking, project tracking, and a dedicated HR resource center with templates and compliance guidance. Premium includes access to certified HR advisors and a compliance alert system - useful if you have no in-house HR person.

OnPay covers the essentials competently: it includes HR tools, an org chart, PTO tracking, document storage, e-signing, and compliance audits at no extra cost across its single plan, which is genuinely generous for the price. But it does not match Gusto's 401(k) integration breadth, on-demand pay, or the depth of curated HR content. Choose Gusto when benefits administration and HR tooling are central to your decision - particularly if you are using payroll as the anchor for your whole people-ops setup. The premium over OnPay's flat rate buys real capability here, not just polish.

Industry specialization: OnPay's advantage for farms, restaurants, and clergy

This is OnPay's sharpest differentiator and a frequent reason to pick it over Gusto. OnPay has built genuine domain expertise for industries with messy, rules-heavy payroll, and it does not charge extra for the specialized handling.

Agriculture and farms: OnPay handles Form 943 (the annual federal tax return for agricultural employees) and understands the distinct wage and tax rules for farm labor, including H-2A visa workers. Most mainstream payroll tools, Gusto included, are built around Form 941 and treat ag payroll as an afterthought. If you run a farm, OnPay's 943 support alone can be the deciding factor.

Restaurants: OnPay manages tip credits, minimum-wage tip make-up calculations, and the FICA Tip Credit (Form 8846) so tipped-employee payroll stays compliant. It supports multiple pay rates per employee and reports tips correctly - the kind of detail that trips up generic payroll when a server works split shifts at different rates.

Clergy and churches: OnPay is unusually strong for religious organizations. It correctly handles dual-status clergy (employees for income tax, self-employed for Social Security/Medicare), housing and parsonage allowances, and the exemption from FICA withholding that applies to ministers. It also supports 501(c)(3) nonprofit FUTA exemption.

OnPay extends similar specialized handling to nonprofits, dental and medical practices, and other niche employers. Gusto serves these businesses too, but you are more likely to hit edge cases that require manual workarounds. Choose OnPay when your payroll has industry-specific tax forms or wage rules that a one-size-fits-all platform would force you to handle by hand - and you want that expertise baked into the flat $40 + $6 price rather than a premium add-on.

Support and ease of use compared

Both platforms are built for non-payroll-experts, and reviewers rate them closely on usability. Gusto carries a 4.5/5 G2 score, helped by a famously friendly onboarding flow and an interface that walks first-timers through tax setup step by step. OnPay posts a strong 4.8/5 on G2 (smaller review volume) and is frequently praised for responsive, knowledgeable US-based support reps who actually understand payroll tax.

On support channels, OnPay leans on phone, email, and chat with real humans and a reputation for hand-holding new accounts through setup and even entering prior payroll history for you at no charge. Gusto offers phone, email, and chat, but phone support hours are more limited on the Simple tier; priority support and a dedicated team come with the higher Plus and Premium tiers. If guaranteed fast human help matters and you do not want to pay up for it, OnPay's flat plan includes full support for everyone.

For day-to-day ease, Gusto's dashboard is slightly more modern and its employee self-onboarding (where new hires enter their own W-4 and direct deposit details) is best-in-class. OnPay's interface is clean and functional - less flashy, but uncluttered and fast once you know where things are.

The takeaway: OnPay edges out Gusto on support inclusivity and headline price, while Gusto wins on interface polish and the breadth of what you can self-serve. Neither will leave a small-business owner stranded - the deciding factor is usually benefits depth (Gusto) versus flat-rate value and industry fit (OnPay).

Frequently asked questions

Do Gusto and OnPay really cost the same? Close, not identical. Gusto Simple is $49/month base plus $6/employee, OnPay is $40/month base plus $6/employee. The per-employee rate matches, so the $9/month base-fee gap stays constant as headcount grows: OnPay is cheaper at 5, 15, or 30 employees.

Why does OnPay have a higher G2 rating than Gusto despite far fewer reviews? OnPay averages around 4.8/5 from roughly 400-880 reviews across G2, Capterra, and Trustpilot combined, versus Gusto's 4.6/5 from over 11,000 reviews. The smaller, more satisfied base fits a tool doing a narrower job (payroll for tipped, agricultural, and nonprofit employers) very well, rather than serving every type of small business.

Does OnPay actually beat Gusto on customer support? Reviewers consistently rate OnPay's support higher, citing knowledgeable US-based reps and full phone/email/chat access on every plan, not gated behind a higher tier. Gusto's complaints, by contrast, cluster around slow response times as the company has scaled.

Which one handles tipped and multi-rate employees better? OnPay, without extra cost. FICA tip credit calculation, tip pooling, and multi-rate overtime blending are built into OnPay's single plan, while Gusto requires manual workarounds for the same scenarios on both Simple and Plus.

Is Gusto worth the premium if I need benefits administration? Yes, if benefits matter to your decision. OnPay does not offer a benefits brokerage marketplace at all, so if you want health, dental, vision, HSA, or 401(k) administered inside your payroll platform, Gusto Plus is the only option between the two.

Which is better for a nonprofit or nonprofit-adjacent business? OnPay. Its FUTA exemption setup and grant-related cost-center tracking are native features that multiple nonprofit HR managers cite as their reason for switching away from Gusto in reviews.
