Short version: if you’ve already elected S-corp status and your net profit reliably clears the mid-$40,000s, Gusto Solo is the simplest way to run compliant owner payroll without hiring a bookkeeper. If your one-person business is outgrowing solo — contractors, seasonal help, benefits on the horizon — Rippling’s broader platform is worth pricing out before you commit. If you want a legacy provider and don’t mind a sales call instead of a published price, ADP RUN stays in the conversation too. None of this is a nudge to elect S-corp status in the first place; that decision belongs with a CPA who can see your actual numbers, not a payroll vendor’s marketing page.
Who should skip this whole comparison? Anyone who hasn’t filed Form 2553 yet. Anyone whose net profit is thin or lumpy month to month. And anyone hoping payroll software will tell them what a “reasonable” owner salary should be — it won’t, and neither will this article. What we can do is show the real cost of running S-corp payroll across three solo revenue tiers, what each platform actually includes, and where the math typically stops making sense.
What actually counts as “reasonable compensation” for an S-corp owner?
The IRS doesn’t publish a formula. Its guidance on S-corp compensation lays out a facts-and-circumstances test: your training and experience, the duties you actually perform, the time and effort you put in, pay for comparable work, your history of distributions versus wages, and any compensation agreement or formula your business uses. Corporate officers who provide services are generally treated as employees for FICA, FUTA, and federal withholding purposes, and the IRS is explicit that once a shareholder-employee takes cash or property from the business, the S-corp is expected to report an appropriate and reasonable salary before anything else moves as a distribution.
That’s the whole mechanism: wages get hit with payroll tax, distributions generally don’t. The temptation is to set salary as low as you can defend and take the rest as distributions. The risk is that “as low as you can defend” is doing a lot of work in that sentence — the IRS can reclassify distributions as wages if your salary wasn’t reasonable, plus penalties and interest. You may also come across claims that recent federal tax legislation changed how reasonable compensation gets calculated for S-corps; as of this writing, IRS guidance still describes the same facts-and-circumstances test rather than a new fixed formula, so treat any claim of a settled percentage as unverified until a CPA confirms it against current guidance. This is the point where a CPA or enrolled agent earns their fee. The software below can execute a salary once one is set; it can’t set it for you.
The 12-month true-cost model: three solo revenue tiers
Adjectives don’t settle this decision — arithmetic does. Here’s how the calculus shifts as net profit climbs, assuming in every case the owner has already elected S-corp status and is now deciding how to run payroll.
Persona A: the $45,000 side-hustle S-corp
At this level, the payroll platform itself is often the biggest line item relative to the benefit. Gusto’s own marketing puts a typical solo owner’s bill around $55 a month for Gusto Solo — roughly $660 a year — before any CPA time spent determining and documenting a defensible salary. On $45,000 of net profit, that’s a meaningful bite, layered on top of whatever a tax professional charges for the S-corp return itself. This is the tier where the honest, if unglamorous, answer is often to stay a sole proprietor a while longer. That’s an editorial heuristic used on this site, not an IRS rule, so treat it as a starting point for a conversation with a CPA rather than a verdict.
Persona B: the $90,000 solo consultant
Here the math tends to flip. There’s enough profit that splitting it between a defensible salary and distributions can meaningfully reduce the share exposed to payroll tax, and a fixed, predictable platform fee becomes a rounding error against the potential savings rather than the main event. This is also the tier where automated quarterly filing genuinely earns its cost: Form 941 is due by the last day of the month following each quarter, and missing that cadence carries penalties that dwarf a $55 monthly software bill. Keep in mind that payroll filings are separate from your personal quarterly obligations — if you’re taking distributions alongside a salary, you may still owe personal quarterly estimated taxes, covered in our quarterly estimated taxes guide for solo owners.
Persona C: the $180,000 agency-of-one
At this income, the Social Security wage base becomes a relevant input — for 2026 it sits at $184,500, meaning Social Security tax stops applying to wages above that level while Medicare tax keeps applying regardless. That doesn’t mean the goal is to engineer a salary near the wage base; it’s simply one more factor a CPA weighs alongside comparable pay and business cash flow. The bigger question at this tier is usually whether you need payroll alone or a fuller operating platform. If you’re adding contractors, weighing benefits, or expect to hire, Rippling’s integrated approach or ADP RUN’s larger service model may justify their higher, or harder-to-see, pricing. If you’re staying a true business-of-one, that added complexity may be paying for features you’ll never open.
| Platform | Est. annual cost, one owner | Pricing model |
|---|---|---|
| Gusto Solo | ≈ $660/year at the advertised ~$55/month | Published, solo-specific |
| Rippling | ≈ $576/year at the published “starting at” rate ($40/month base plus $8/month per user) — treat as a floor, not a guarantee | Starting price plus custom quote (contested) |
| ADP RUN | Not published for a single owner | Quote required |
The Rippling figure deserves a flag: Rippling’s main pricing page says it issues custom quotes, while its small-business page advertises a starting rate. Both statements are currently live on Rippling’s own site, so the honest read is “starting around there, confirm with sales” rather than a fixed number.
Gusto Solo, Rippling, and ADP RUN: what each one actually does
If none of these three fit — say you’re not yet an S-corp, or you need a plan for more than one payroll recipient — our broader payroll software roundup covers options built for teams rather than a single owner.
Gusto Solo
Gusto Solo is built specifically for solopreneurs and one-employee S-corps, and it shows: guided help filing Form 2553, a reasonable-salary calculator that offers a starting range rather than a verdict, automated tax withholding, quarterly filings, W-2 and 1099 generation, and a compliance hub that tracks deadlines for you. Pricing runs $49 a month base plus $6 a month per payroll recipient, and Gusto markets the typical solo bill at around $55 a month as of 2026 — check the live rate before you commit, since these figures move.
The honest limitation: Gusto itself points out that an accountant still matters for the S-corp election, estimated tax planning, and owner health insurance or HSA questions. It’s payroll execution, not tax strategy. Gusto also files forms only for the quarters when payroll actually runs, so any gap in your own payroll history is still on you to track. Skip Gusto Solo if you haven’t elected S-corp status yet, or if your business has grown past “just me” — Gusto’s Simple, Plus, and Premium tiers price differently and may fit better once you add employees or contractors beyond yourself.
Rippling
Rippling is less a payroll product and more a platform that happens to include payroll — HR, IT, time tracking, and benefits all live under one roof, and Rippling says payroll can run on your own schedule at no extra charge, with support for federal, state, and local filings plus W-2 and 1099 generation. For a solo owner who expects to add people soon, that breadth can save a future migration headache.
The honest limitation: pricing is genuinely hard to pin down from the outside. You may need a sales conversation to get a real number, and for a single owner who only needs compliant payroll, Rippling’s platform depth is likely more than you need today. Skip it if all you want is simple owner payroll at a price you can see without a call.
ADP RUN
ADP RUN carries the brand recognition of a payroll company that has been running this exact process for decades, and its small-business pages emphasize service and support alongside the standard payroll mechanics — direct deposit, tax filing help, and packages built around headcount.
The honest limitation: ADP’s public pages don’t advertise a simple one-owner price the way Gusto Solo does. Pricing depends on pay frequency, how many people you pay, and how often that changes, which means solo cost comparison requires requesting a quote rather than reading a page. Skip it if transparent, published pricing matters more to you than brand pedigree.
Where S-corp payroll fits in your financial OS
Payroll compliance sits in the Foundation layer of a solo operator’s financial stack — it isn’t glamorous, but everything else, from tax filings to retirement contributions to loan applications that ask for W-2 income, depends on it being right. It pairs directly with your entity-election decision and your bookkeeping system, and it has a real downstream effect on retirement planning: to make an employee-side 401(k) deferral as an S-corp owner, you generally need W-2 wages to defer from. The 2026 employee deferral limit is $24,500, with an overall defined-contribution limit of $72,000 once employer contributions are added, and the 2026 IRA limit sits at $7,500 ($8,600 if you’re 50 or older). Skip the S-corp-and-payroll conversation and you also skip that lever. For readers building out the rest of the stack, our S-corp election guide and solo 401(k) guide go deeper on both pieces.
One more solo-specific detail worth knowing: if your S-corp reimburses you for business mileage under an accountable plan, the 2026 standard mileage rate is 72.5 cents per mile from January through June and 76 cents per mile from July through December — a small administrative detail, but one more thing your payroll or bookkeeping workflow should track accurately rather than estimate.
Skip S-corp payroll software entirely if…
You haven’t actually filed the S-corp election yet — see our guide to paying yourself as a freelancer first. Your net profit is inconsistent enough that a fixed monthly software fee feels risky some months. You’re still weighing entity types and haven’t run the numbers with a CPA. Or you simply don’t yet know what a defensible salary looks like for your role — that conversation needs to happen before any platform gets involved, not during onboarding.
Bottom line
For most solo owners who’ve already made the S-corp election and are clearing somewhere around $60,000 to $90,000 or more in net profit, Gusto Solo is the platform built for exactly this job — published pricing, guided setup, and automated filings that keep you off the IRS’s radar for the wrong reasons. Rippling earns a look once you’re adding people or benefits beyond yourself. ADP RUN is worth a quote if brand and support matter more to you than seeing a price up front. None of these platforms replace a CPA’s judgment on what your salary should actually be — that’s the one number in this whole article you shouldn’t set alone.
