Is it right for you?

  • Are you operating as an S-corp, single-member LLC, or sole proprietor? The answer changes which software you need and whether you're paying yourself as a W-2 employee.
  • Do you have clients in multiple states? If so, you need multi-state payroll tax filing, not every tool charges the same for it.
  • Will you be mixing W-2 employees and 1099 contractors? Some tools handle both cleanly; others are clunky for hybrid workforces.
  • Do you want the software to file and pay payroll taxes automatically, or are you comfortable doing that yourself to save money?
  • Are you already using QuickBooks Online, Xero, or another accounting platform? Native integration will save you hours of reconciliation.
  • Do you need solo 401(k) support baked in, or are you managing retirement contributions separately through a brokerage?

Quick verdict

For most solo consultants running an S-corp, Gusto's Simple plan is the clearest starting point, it handles S-corp salary + distributions, automated federal/state tax filings, and solo 401(k) in one place without requiring an accountant to set it up. If budget is the main constraint, Patriot's Full Service Payroll at $37/month is the most cost-effective option that still handles all tax filings automatically.

The short answer: what consultants actually need from payroll software

Payroll for consultants is deceptively complex. If you're a sole proprietor taking an owner's draw, you technically don't need payroll software at all, you pay self-employment tax on net profit and make quarterly estimated tax payments. But the moment you elect S-corp status (which many consultants do once income clears roughly $50,000–$60,000 per year to save on self-employment tax), you become both employer and employee, and you need a proper payroll system.

The S-corp structure requires you to pay yourself a 'reasonable salary' via W-2 payroll, withhold and remit FICA taxes (Social Security and Medicare), file Form 941 quarterly, and issue yourself a W-2 at year-end. The remaining profit flows to you as an owner's distribution, which is not subject to self-employment tax, that's the tax savings. But this structure also means you can't skip a payroll run without creating IRS exposure.

Consultants who work across multiple states face an additional layer: if you or any employees work from different states, you may owe payroll taxes and need to register in those states. If you bring on subcontractors, you need 1099-NEC generation at year-end. And if you want to maximize retirement contributions through a solo 401(k), both employee and employer contributions, your payroll software needs to handle those deductions cleanly without you manually reconciling everything each pay period.

Quick comparison: payroll software pricing for consultants

The four tools most commonly used by independent consultants and small consulting firms are Gusto, Patriot Software, QuickBooks Payroll, and OnPay. Each has a meaningfully different pricing model, and the cheapest monthly base fee doesn't always translate to the lowest total cost when you factor in per-employee fees and add-ons.

SoftwareBase Fee/MonthPer Employee/MoTax Filings IncludedBest For
Gusto Simple$40$6Yes (federal + state)S-corp owners, solo + small teams
Patriot Full Service$37$5Yes (federal + state + local)Budget-conscious solo consultants
QuickBooks Payroll Core$45$6Yes (federal + state)Existing QuickBooks Online users
OnPay$40$6Yes (federal + state)Multi-state, HR-focused consultants
Wave Payroll$20 (self-service) / $35 (full-service)$6Full-service plan onlyFreelancers wanting free accounting bundled

Note: QuickBooks Payroll is frequently bundled with QuickBooks Online accounting software. If you're already paying for QBO (which starts at $35/month for Simple Start), adding payroll can be cost-effective. Patriot Software's pricing shown is at regular (non-promotional) rates. Wave's self-service plan at $20/month requires you to file your own payroll taxes, not a good fit if you want true hands-off compliance.

Gusto: The S-Corp Consultant's Default Choice

Gusto is the most widely recommended payroll tool among independent consultants running S-corps, and that reputation is largely earned. The Simple plan at $40/month plus $6 per employee per month gives you full-service payroll with automated federal and state tax filings, direct deposit, W-2 generation, and a self-service employee portal. For a solo S-corp owner paying themselves a salary twice a month, the math works out to $52/month, a reasonable price for full compliance.

Where Gusto stands out is usability. The setup flow for paying yourself as an S-corp shareholder-employee is straightforward: you enter your reasonable salary, set a pay schedule, and Gusto handles withholding calculations for federal income tax, Social Security, Medicare, and state taxes. It also supports officer-only payroll, meaning you don't need to set up a complex org structure just to pay yourself.

Gusto's benefits integrations are also relevant to consultants. It connects directly with several solo 401(k) providers, health insurance brokers, and HSA administrators, useful if you're trying to build a benefits package without a full HR team. The software integrates with QuickBooks Online, Xero, and FreshBooks for accounting sync. One real limitation: Gusto's support has drawn consistent criticism from users who report long wait times and inconsistent answers, particularly around state tax registration issues. If your S-corp is newly formed or you're adding a new state, plan to do some of that groundwork yourself rather than relying on Gusto's support team.

Patriot software: the budget-first option that actually works

Patriot Software's Full Service Payroll plan at $37/month plus $5 per employee per month is meaningfully cheaper than competitors and includes federal, state, and local payroll tax filings. For a solo consultant paying themselves, this comes out to approximately $42/month, roughly $10/month less than Gusto's equivalent. Over a year, that's $120 in savings, which isn't life-changing but is real.

Patriot's interface is more utilitarian than Gusto's, but it gets the job done. It supports W-2 employees and 1099 contractors, handles unlimited payroll runs per month, offers direct deposit, and provides an employee self-service portal. The software also offers an accounting add-on starting at $20/month if you want to consolidate. For consultants who already work with a bookkeeper or CPA who handles their QuickBooks, Patriot may be redundant on the accounting side, but as a standalone payroll tool, it's solid.

The main trade-off with Patriot is features and integrations. It doesn't have the breadth of Gusto's benefits ecosystem or the same depth of integrations with third-party HR tools. If you plan to add employees, offer health benefits, or want a polished onboarding experience, Patriot starts to show limitations. But for a solo consultant or a small 2–3 person consulting firm that just needs reliable, affordable payroll and tax filing, Patriot delivers exactly what it promises at a price that's hard to argue with.

What real users say: common complaints and praise

Across reviews on G2 and Capterra, Gusto consistently earns ratings in the 4.4–4.6 out of 5 range. The most common praise centers on ease of use during initial setup, clean interface design, and the automated tax filing removing a major compliance burden. Gusto's G2 score as of 2025 sits at approximately 4.5/5 across several thousand reviews, a strong signal for a B2B software product at this price point.

The most consistent complaints about Gusto from small business and consultant users involve customer support and pricing increases. Multiple users on forums like Reddit's r/smallbusiness and r/financialindependence have noted that Gusto's support response times degraded as the company grew, and that the platform raised prices without much notice. Several S-corp consultants have noted that Gusto doesn't automatically remind you to pay estimated quarterly taxes on your distribution income, you still need to track those separately or use a tool like QuickBooks Self-Employed alongside your payroll software.

Patriot Software earns praise specifically from price-sensitive users. On Capterra it holds a 4.8/5 rating, with reviewers frequently calling out the customer support team as a differentiator, Patriot still offers phone support during business hours (9 AM–7 PM ET, Monday–Friday), which larger competitors have largely moved away from. The consistent complaint is that Patriot's reporting is basic, integrations are limited, and the interface feels dated. For consultants who want simple, affordable, and reliable, and don't need a polished modern UI, Patriot's user satisfaction is genuinely high. QuickBooks Payroll draws mixed reviews from consultants: users who are already inside the QBO ecosystem love the native sync, but those who switched from QBO to another accounting tool often feel trapped paying for a bundled product they don't fully use.

Multi-state payroll: what consultants need to know

Multi-state payroll is one of the most underestimated complications for consultants. If you're a New York-based IT consultant with clients in California and Texas, the question is where your work is physically performed. If you're working remotely from New York for a California client, you generally owe New York taxes only. But if you travel to client sites, or if you hire a team member who lives in a different state, you create nexus in that state and need to register as an employer there.

All four major tools, Gusto, Patriot, QuickBooks Payroll, and OnPay, support multi-state payroll. However, the setup burden and cost vary. Gusto charges no additional fee for multi-state payroll on its paid plans, but you are responsible for completing state employer registrations before running payroll in a new state. Gusto does offer a registration service but it comes at an additional cost and has received mixed reviews for accuracy and speed. OnPay is frequently cited by accountants who work with multi-state small businesses as being particularly clean in its multi-state handling, with clear state-by-state tax setup and a one-flat-fee pricing model.

The practical advice for most consultants is: if you're currently single-state and growing, start with Gusto or Patriot. If you already have employees in multiple states, or you know you'll be hiring across state lines, evaluate OnPay more seriously. Its $40/month + $6/employee flat pricing (no tiers) means you're not paying more for more features you don't need, and its multi-state compliance workflows are cleaner than what you get from entry-level Gusto or Patriot plans.

Consultants vs. consulting firms: different needs at different scales

The payroll needs of a solo IT consultant running an S-corp are fundamentally different from those of a 10-person management consulting firm. The solo consultant needs: S-corp owner payroll, automated quarterly tax remittances, W-2 generation, and 1099-NEC filing for any subcontractors. That's it. Gusto Simple or Patriot Full Service handle this cleanly for under $55/month.

A small consulting firm with 5–15 employees adds complexity fast. Now you need multiple W-2 employees, potentially benefits administration (health insurance, 401(k)), PTO tracking, expense reimbursement workflows, and onboarding compliance across multiple states if you hire remotely. At this scale, the conversation shifts: Gusto's Plus plan (which adds HR features) becomes relevant, as does Rippling for firms that also want IT management bundled. QuickBooks Payroll with QBO Essentials or Plus is a common choice for firms that have a dedicated bookkeeper.

Management consulting firms specifically, where employees work at client sites in different cities and states, often run into the most complex payroll tax situations. Some consultants find that mid-tier software like Gusto Plus or OnPay becomes insufficient once they cross 15 employees and have complex benefit structures. At that point, tools like Rippling (which starts around $8/month per employee for the base module, but requires platform fee negotiation) or ADP Run become relevant. Those platforms are priced higher and designed for businesses that have an HR owner, not just a solo founder doing payroll themselves.

Frequently Asked Questions

Do I need payroll software if I'm a sole proprietor consultant? Probably not. Sole proprietors don't run payroll, they pay self-employment tax on net profit and make quarterly estimated payments to the IRS using Form 1040-ES. You only need payroll software if you have employees (including yourself as an S-corp employee) or want to pay 1099 contractors through a trackable system.

Can Gusto handle S-corp owner payroll where I'm the only employee? Yes, and this is actually one of Gusto's most common use cases among small business owners. You set yourself up as an employee of your S-corp, enter a reasonable salary, choose a pay frequency (biweekly or semimonthly is common), and Gusto calculates and remits withholding automatically. You still need to make quarterly estimated payments on your distribution income separately, payroll software doesn't cover that.

How do I handle 1099 contractors through payroll software? Most modern payroll tools, including Gusto, Patriot, QuickBooks Payroll, and OnPay, let you add contractors alongside employees. You track payments made to them during the year, and the software generates and e-files 1099-NEC forms at year-end. Some tools charge an extra fee for 1099 e-filing; Patriot notably includes it at no extra charge.

What's the difference between self-service and full-service payroll? With self-service payroll (like Wave's lower-tier plan), the software calculates what you owe in payroll taxes but you are responsible for making the deposits and filing the returns yourself. With full-service payroll (like Gusto, Patriot's Full Service plan, OnPay), the software handles deposits and filings automatically. For consultants who don't want tax compliance risk, full-service is almost always the right choice.

Do any of these tools integrate with solo 401(k) providers? Gusto has direct integrations with several 401(k) providers and can deduct both employee and employer contributions automatically from payroll. QuickBooks Payroll integrates with Vestwell for 401(k) administration. Patriot does not have native 401(k) integrations, you'd need to set up contributions manually or through your plan administrator. For solo 401(k) specifically, most administrators (like Vanguard, Fidelity, or Schwab) require you to make employer contributions directly and just provide documentation from payroll software, so the integration gap matters less than you might think.

What to do next

Most payroll tools offer a free trial or free setup month. We recommend testing 2–3 options with a real payroll run before committing to an annual contract.
