Best Payroll Software for Small Business in 2026

You just hired your first employee, or your second, and you’ve been manually calculating tax withholdings in a spreadsheet while quietly dreading what happens when you file the wrong quarterly amount with the IRS. Or you’re already using ADP, you’ve never fully understood what you’re paying, and your monthly bill just went up without a clear explanation. Either way, payroll software for a small business should do three things: run payroll without you knowing much about tax law, file your federal and state payroll taxes automatically, and not nickel-and-dime you for every form at year-end. I’ve set up payroll for small businesses ranging from sole proprietors to 40-person teams, and the short list is shorter than most roundups suggest.

Key Takeaways

Gusto is the best overall payroll software for most small businesses — but it raised its Simple plan from $40 to $49/month in March 2026, narrowing its value edge over competitors. At $49/month + $6/employee, a 10-person team pays $109/month. That’s still reasonable for what’s included, but it’s no longer the clear-cut cheapest option it was 18 months ago.

OnPay at $40/month + $6/employee is the best-value alternative to Gusto for small businesses that want full-service payroll with no tier gating. Every feature OnPay offers — multi-state payroll, unlimited payroll runs, HR tools, W-2/1099 filing — is included at one price regardless of headcount.

Square Payroll at $35/month + $6/employee is the best pick if you already use Square for point-of-sale. The native integration means tips, hours, and overtime flow directly into payroll without manual data entry, which removes the main reconciliation headache for retail and restaurant operators.

Avoid building your payroll on ADP or Paychex as a small business unless you specifically need their compliance depth for a complex or multi-state setup. Neither publishes pricing, both use aggressive upselling via sales calls, and most small businesses pay more than they need to for services a simpler platform handles just as well.

What to Look for in Payroll Software

Payroll for a small business has one non-negotiable requirement: full-service tax filing. That means the software calculates your federal, state, and local payroll taxes, pays them on your behalf, and files the quarterly 941 and annual W-2s and 1099s automatically. If you’re manually downloading forms and mailing quarterly checks to the IRS, you’re not using full-service payroll — you’re using a calculator.

Full-Service vs Self-Service Payroll

Full-service payroll (Gusto, OnPay, Square, Rippling) files and pays your taxes for you and carries the tax penalty liability if something goes wrong due to the software’s error. Self-service payroll (Wave Payroll in some states, DIY options) gives you the numbers but leaves you to file everything yourself. For a small business owner without a bookkeeper, self-service is a tax mistake waiting to happen. Always confirm which type you’re buying before you run your first payroll.

Pricing Structure Matters More Than the Base Price

The original observation most payroll software comparisons skip: the monthly base fee is the least important number in the equation. What matters is the total cost at your actual headcount, whether multi-state payroll is included or costs extra, and whether year-end W-2 and 1099 filing is included or billed as a surprise in January. Gusto and OnPay both include year-end processing in all plans. ADP and some legacy providers charge separately per W-2 form delivered to employees. Those per-form fees add up on a 25-person team.

The Multi-State Trigger

If you have employees in more than one state, your payroll tool needs multi-state support — and many entry-tier plans don’t include it. <cite index=”30-1″>Gusto will not process multi-state payroll on the Simple plan — the moment you hire someone in a second state, you’re forced to upgrade from Simple ($49 + $6/employee) to Plus ($80 + $12/employee).</cite> On a 15-person team, that single hire in another state jumps your monthly bill from roughly $139 to $260. Know your growth plan before you pick a plan tier.

Best Overall Payroll Software — Gusto

<cite index=”29-1″>Gusto is the most widely used payroll platform for small businesses in the US, serving more than 400,000 businesses.</cite> Its Simple plan at $49/month + $6/employee (following the March 2026 price increase from $40) covers full-service payroll for a single state, unlimited payroll runs, automated tax filing, W-2 and 1099 year-end processing, employee self-service, basic onboarding tools, and health insurance administration — all in a clean, browser-based interface most business owners can navigate without a payroll background.

Plan Breakdown and Real Team Costs

<cite index=”24-1″>Gusto pricing in 2026 runs: Simple at $49/month + $6/employee; Plus at $80/month + $12/employee; Premium at $180/month + $22/employee. The Contractor Only plan starts at $35/month + $6/contractor.</cite>

Real monthly costs at common team sizes:

• 5 employees, Simple: $49 + $30 = $79/month
• 10 employees, Simple: $49 + $60 = $109/month
• 10 employees, Plus: $80 + $120 = $200/month
• 20 employees, Simple: $49 + $120 = $169/month
• 20 employees, Plus: $80 + $240 = $320/month

Plus is worth it specifically when you need multi-state payroll, next-day direct deposit, or Gusto’s built-in time tracking. If your team is in one state with standard two-day direct deposit, Simple covers you fully .Gusto also goes head to head with ADP in a full comparison — our Gusto vs ADP guide covers the hidden fees, per-run charges, and which one actually costs less for a small business once all fees are included.

What Makes Gusto Worth It

No per-run charges (unlimited payrolls including off-cycle runs for bonuses), W-2 and 1099 generation included in all plans, and a genuinely clean interface that doesn’t require training to run payroll on day one. It integrates natively with QuickBooks Online, Xero, FreshBooks, and most accounting tools, so your bookkeeping and payroll sync without CSV exports.

The Honest Limitations

<cite index=”29-1″>The most repeated criticism across review sites is inconsistent support — priority support and HR advisors sit on the Premium plan, and the mobile app trails the desktop experience.</cite> Gusto has also raised its Simple base fee twice in 12 months, which makes multi-year budgeting harder than it used to be. And for businesses with complex hourly workforces — restaurants with tip pooling, shift-based retail, multi-location operations with variable schedules — Gusto’s scheduling and time tools aren’t purpose-built for that complexity.

Best Budget Alternative — OnPay

OnPay at $40/month + $6/employee is the best payroll alternative for small businesses that want Gusto-level functionality without tier gating. Every feature is included in one plan: multi-state payroll, unlimited payroll runs, W-2 and 1099 filing, HR tools, garnishment processing, and onboarding support — no upgrade required regardless of which state you hire in.

Why OnPay Beats Gusto on Simplicity

<cite index=”31-1″>OnPay offers simpler pricing with no feature lockout — unlike Gusto, where hiring a single employee in a second state forces a plan upgrade that doubles your per-employee cost.</cite> For a business with employees in two or three states, OnPay’s flat structure saves $31/month on the base fee compared to Gusto Plus, plus $6/employee/month on every person. A 15-person multi-state team pays roughly $130/month on OnPay versus approximately $260/month on Gusto Plus. That gap is real money.

OnPay’s Limitation

OnPay’s ecosystem is smaller than Gusto’s. Fewer native integrations, less name recognition among accountants and bookkeepers, and its benefits administration options (health insurance, 401k) are more limited than Gusto’s broker network. For a business that wants full health insurance administration alongside payroll, Gusto’s benefits infrastructure is meaningfully deeper .If you are also evaluating Rippling as a more complete HR and payroll platform, our Rippling vs Gusto comparison breaks down exactly when Rippling’s modular pricing justifies the premium over simpler payroll tools.

Best for Square POS Users — Square Payroll

Square Payroll at $35/month + $6/employee is the best payroll option for retail stores, restaurants, coffee shops, and any business already using Square for payments. Tips entered in Square POS flow directly into payroll calculations, hours tracked in Square’s timeclock sync automatically, and the entire reconciliation problem that plagues mixed-system setups disappears.

The Contractor-Only Plan

Square Payroll’s contractor-only tier is $6/contractor/month with no base fee — the cheapest contractor payment option among full-service payroll providers. If your business has no W-2 employees and only pays 1099 contractors, Square’s contractor plan handles payments and 1099 filing at a lower cost than Gusto’s $35/month contractor plan.

Where Square Falls Short

Square Payroll’s HR features are minimal compared to Gusto or OnPay — basic employee profiles but no performance tools, limited onboarding, and no built-in benefits administration. For a business that just needs to pay people and file taxes, that’s fine. For a business building out HR processes alongside payroll, Square will leave gaps.

Best for QuickBooks Users — QuickBooks Payroll

If you’re already on QuickBooks Online and your accountant lives in that system, QuickBooks Payroll Core at $45/month + $6/employee is the path of least resistance. Payroll data syncs directly into QuickBooks without any manual journal entries or integration setup, which removes the biggest bookkeeping headache for businesses that pay a CPA by the hour to reconcile payroll entries.

The Trade-Off on Price and Features

QuickBooks Payroll Core is slightly more expensive than Square ($35) but cheaper than Gusto Simple ($49) at the base tier, and its main value is the QuickBooks sync rather than any payroll feature that outperforms competitors. Premium at $80/month + $8/employee adds same-day direct deposit and HR support. Elite at $125/month + $10/employee adds a personal HR advisor and tax penalty protection (the software pays any penalties caused by its own errors). For a business already paying for QuickBooks, the bundled pricing sometimes includes payroll at a discount — worth checking the current QuickBooks billing page before adding it separately.

How to Choose the Right Payroll Software

The decision is more mechanical than most software choices. Run through these filters in order.

Step 1: Do You Have W-2 Employees or Just Contractors?

If you only pay 1099 contractors — designers, developers, freelancers — you don’t need a full payroll platform at all. Gusto Contractor Only ($35/month + $6/contractor), Square Contractor ($6/contractor, no base fee), or even a simple payments tool handles contractor payments and 1099 filing without the W-2 payroll overhead. Buy only what you need.

Step 2: Are You in One State or Multiple?

Single state, under 15 employees: Gusto Simple at $49/month + $6/employee or Square Payroll at $35/month + $6/employee. Both cover the basics cleanly. Multiple states: OnPay at $40/month + $6/employee is often cheaper than Gusto Plus at $80/month + $12/employee for the same multi-state capability.

Step 3: Do You Already Use Square or QuickBooks?

Already on Square for POS: Square Payroll. It removes the tip and timesheet reconciliation problem that every other platform creates. Already deep in QuickBooks: QuickBooks Payroll Core syncs payroll directly into your books without any middleware.

Step 4: Do You Need HR Tools Alongside Payroll?

Basic offer letters, I-9 and W-4 collection, employee self-service for pay stubs: Gusto Simple covers this. Time tracking, performance reviews, and HR advisory: Gusto Plus or Premium. A full HR + IT platform managing devices and apps alongside payroll: Rippling, which starts at around $8/user/month for just payroll but prices modularly and gets expensive quickly as you add HR and IT modules .If HR tools matter as much as payroll for your team, our best HR software for companies under 50 employees covers BambooHR, Homebase, and Gusto’s HR layer with real pricing comparisons.

Frequently Asked Questions

What is the best payroll software for a small business?

Gusto is the best overall payroll platform for most small businesses at $49/month + $6/employee on the Simple plan — it handles full-service tax filing, W-2/1099 year-end processing, and employee self-service in a clean interface most owners can run without payroll experience.

Is there any truly free payroll software for small businesses?

There is no genuinely full-service free payroll platform — any tool that files and pays your payroll taxes on your behalf charges a fee. Wave Payroll in self-service states costs $20/month + $6/employee, which is the cheapest entry at the low end, though you handle some tax filing yourself in self-service states.

Is Gusto better than ADP for small business?

For most small businesses under 50 employees, Gusto is the better choice — it has transparent public pricing, a simpler interface, and includes W-2/1099 year-end filing without extra fees, while ADP’s quote-driven pricing and add-on structure often ends up costing small businesses more than Gusto for comparable features.

Does Square Payroll work if I don’t use Square for payments?

Yes — Square Payroll operates independently of Square’s payment processing and can be used as a standalone payroll system without a Square POS account, though the primary advantage of Square Payroll is its native integration with Square’s time tracking and tips, which matters most for businesses that do use Square POS.

What payroll software integrates with QuickBooks Desktop?

QuickBooks Payroll (online version) works with QuickBooks Online but not QuickBooks Desktop directly. For QuickBooks Desktop users, ADP and Paychex both have integrations, and Gusto also connects via an accountant partner setup, though syncing is less seamless than native QuickBooks Online integration.

Can payroll software handle 1099 contractors and W-2 employees on the same platform?

Yes — Gusto, OnPay, QuickBooks Payroll, and Square Payroll all support both W-2 employees and 1099 contractors in the same account, handling 1099 form generation at year-end alongside W-2 forms with no separate contractor-only platform required.

How much does payroll software cost for a business with one employee?

On Gusto Simple, a business with one employee pays $49 + $6 = $55/month. Square Payroll is $35 + $6 = $41/month. OnPay is $40 + $6 = $46/month. For a business with only one or two employees, Square Payroll is consistently the cheapest full-service option.

Conclusion

For most small businesses hiring their first few employees in one state, Square Payroll at $35/month + $6/employee is the cheapest clean option — and Gusto Simple at $49/month + $6/employee is the better pick the moment you want more HR tools, benefits administration, or a wider integration ecosystem. If you’re in multiple states from the start, go OnPay at $40/month + $6/employee and skip Gusto’s forced upgrade to Plus. Whatever you pick, confirm it’s full-service — automated tax filing and payment, not just payroll calculation.
