LLC vs S-Corp: The Real Tax Difference

For a small business in New York City, the LLC vs S-Corp question almost always comes down to profit, because the two are not really alternatives in the first place. An LLC is your legal entity, formed under New York state law when you file Articles of Organization with the Department of State. An S-corp is a federal tax election you can place on top of that LLC. So the real LLC vs S-Corp question isn’t “which one do I pick,” it’s “should my LLC make the S-corp election or stay taxed the default way,” and in New York City the honest answer leans toward “later than you’d think,” because the city makes the math worse than it is almost anywhere else in the country.

Start with the federal layer, because that’s where the savings come from. A default LLC pays self-employment tax on all of its net profit. That’s 15.3% total — 12.4% for Social Security up to the 2026 wage base of $184,500, plus 2.9% for Medicare with no cap, and an extra 0.9% Medicare surtax once your income crosses $200,000 single or $250,000 married filing jointly. An LLC that elects S-corp status under Subchapter S splits the owner’s pay into a reasonable W-2 salary, which gets payroll tax, and distributions, which don’t. The distribution piece is the only savings. Federally, that starts to make sense around $80,000 to $100,000 of net profit, once the savings beat the $2,000 to $5,000 a year an S-corp adds in payroll, a separate return, and bookkeeping. Below that profit band, a default LLC usually wins on total cost.

Now the New York City problem, which is the part that catches people and the reason the LLC vs S-Corp answer is different in the five boroughs. New York City does not recognize S-corp status at all. The city taxes your S-corp under the General Corporation Tax as if you never made the election, per the NYC Department of Finance. So part of the federal self-employment tax you saved by taking distributions gets clawed back by the city’s corporate-level tax. The practical effect: the LLC vs S-Corp break-even in NYC sits higher than the national rule of thumb. We’ve watched businesses that would clearly benefit from an S-corp in New Jersey or Texas come out roughly even in New York City once the GCT lands in the calculation. That’s not a reason to never elect. It’s a reason to run the city tax before you do.

There’s a state layer sitting between the two. New York doesn’t automatically honor your federal S election. You file a separate Form CT-6 with the New York State Department of Taxation and Finance, or the state taxes your entity as a C-corporation at the state level, which throws away the benefit on your state return. And one genuinely useful piece of good news: New York’s Pass-Through Entity Tax (PTET) lets a profitable S-corp pay state tax at the entity level and effectively work around the federal $40,000 SALT cap on your personal return, recovering deductions you’d otherwise lose. For a higher-income NYC owner, PTET can be worth real money, and it partly offsets the GCT sting. Both belong in the same calculation, which is the whole point: the LLC vs S-Corp answer in this city has more moving parts than the federal version.

Here’s a concrete example of how the LLC vs S-Corp comparison plays out locally. A Brooklyn consultant clears $130,000 in net profit. Federally, electing S-corp status with an $80,000 salary and a $50,000 distribution saves roughly $6,000 to $7,000 in self-employment tax under the IRS S-corporation rules. But the NYC GCT takes a bite the consultant wouldn’t pay in most other cities, so the real net savings might land closer to $3,000 to $4,000 after the city tax. Still worth doing at that profit level, but not the headline number a generic online calculator would show. Below about $90,000 of profit, a New York City business often finds the S-corp barely breaks even once you stack the city tax on top of the added compliance costs. The election isn’t wrong there, it just isn’t paying for itself yet.

One more thing specific to operating in the city. Because New York City taxes the entity itself under the General Corporation Tax, the value of the S-corp election in the LLC vs S-Corp comparison depends partly on how much of your work and income is actually sourced to the city versus elsewhere. A consultant who lives in Manhattan but bills clients all over the country has a different GCT exposure than one whose entire book of business is local, and that changes the break-even. We also see owners forget that the GCT has a minimum tax tied to receipts, so even a low-profit year carries a city bill the S-corp structure doesn’t escape. None of this kills the strategy. It just means the clean federal LLC vs S-Corp math you’d run for a business in Florida needs a city overlay before you trust the result in the five boroughs.

The honest answer for most small NYC businesses: stay a default LLC until your profit is comfortably into six figures, then run the actual numbers including the GCT and the PTET before you elect. Don’t trust a national rule of thumb in a city that doesn’t follow national rules. If you want that comparison done right, our entity formation and structuring team runs the full LLC vs S-Corp analysis with the New York City tax baked in, so you’re deciding on your real numbers instead of guessing. An S-corp is not right for every NYC business, and in this city, electing too early is an even more common and expensive mistake than it is everywhere else. The LLC vs S-Corp decision rewards patience here in a way it doesn’t in lower-tax states. And if you’ve already elected and are second-guessing it after seeing your first city tax bill, that’s worth a conversation too. An S-corp election can be revoked, though doing so has its own timing rules and a five-year wait before you can re-elect, so it’s not a decision to flip back and forth on. Get the LLC vs S-Corp call right once, with the New York City numbers in front of you, and you won’t have to revisit it every spring.

The S-corp election saves money in exactly one way, and understanding the LLC vs S-Corp difference here is mostly about understanding that single mechanism. It comes down to how your pay gets taxed for Social Security and Medicare. On a default LLC, every dollar of net profit is subject to self-employment tax. On an S-corp, only the part you pay yourself as a salary is. The rest comes out as a distribution that skips self-employment tax entirely. That gap, salary versus distribution, is the whole game. There is no second mechanism hiding behind it, which is why the LLC vs S-Corp savings are easier to understand than most people assume.

Let’s put real numbers on it, because this is the kind of thing that only makes sense with a worked example. Self-employment tax is 15.3% — 12.4% for Social Security up to the 2026 wage base of $184,500, plus 2.9% for Medicare with no income ceiling. If you’re over $200,000 single or $250,000 married filing jointly, there’s an extra 0.9% Medicare surtax stacked on top. On a default single-member LLC reporting $130,000 of profit on Schedule C, you’d owe self-employment tax on about 92.35% of that (the IRS lets you knock off half the tax before computing the base), which is roughly $18,400 for the year, before any income tax even enters the picture. The IRS explains the structure on its self-employment tax pages and lays out the broader S-corporation rules here.

Now elect S-corp status with that same $130,000 in profit. You pay yourself a reasonable salary — say $80,000 — and take the remaining $50,000 as a distribution. Payroll tax (which is the same 15.3%, just collected through payroll instead of on Schedule SE) applies only to the $80,000 salary, costing about $12,240 in Social Security and Medicare. The $50,000 distribution pays zero self-employment tax. Your savings: roughly $6,000 for the year. Same profit, same business, same write-offs, same client list. The only thing that changed is that $50,000 moved from the self-employment-taxed column into the distribution column. That’s the entire LLC vs S-Corp tax advantage in one sentence.

Notice what the S-corp does not do, because this is where bad advice lives. It doesn’t give you new deductions. It doesn’t lower your income tax — that $130,000 is still income to you either way, salary plus distribution, taxed at your regular rates. It doesn’t change your liability protection, which came from the LLC, not the tax election. The Qualified Business Income deduction is available to both a default LLC and an S-corp if you qualify. The only thing the election changes is the self-employment tax on the distribution portion of your profit. If anyone pitches you an S-corp on the basis of secret write-offs or magic deductions, they’re wrong, and I’d be skeptical of the rest of their advice too.

The catch — and it’s a real one that the internet glosses over — is that those savings have to clear the cost of running an S-corp. You now have to run payroll and file Form 941 every quarter, file Form 940 annually for federal unemployment, issue yourself a W-2 in January, file a separate Form 1120-S by March 15, and keep clean books with a real balance sheet. That’s $2,000 to $5,000 a year in added cost. At $130,000 of profit, saving $6,000 against $3,000 in costs nets you a solid $3,000 a year. At $50,000 of profit, that same $3,000 in costs would swallow nearly all of a much smaller savings, and the election goes from smart to pointless. So the LLC vs S-Corp answer flips entirely depending on where your profit sits.

It’s also worth saying what happens to the savings as your income climbs, because the LLC vs S-Corp gap doesn’t grow forever in a straight line. Once your salary passes the 2026 Social Security wage base of $184,500, the 12.4% Social Security piece stops applying to additional salary, so the bulk of what’s left to save shifts to the 2.9% Medicare portion (plus the 0.9% surtax over $200,000 single or $250,000 married filing jointly). The practical effect: a very high earner already paying themselves a six-figure salary captures most of the S-corp benefit on the Medicare side, and the marginal savings on each additional distribution dollar shrink. That’s not a reason to skip the election at high income, where the dollars are still large. It’s a reason not to assume the percentage savings hold steady as you scale.

The other catch is the salary itself. The savings grow the more you take as distribution, which tempts owners to pay themselves a tiny salary and pull the rest out untaxed. The IRS watches this closely and will reclassify an unreasonably low salary as wages, with back taxes and penalties attached. So the LLC vs S-Corp savings are real but bounded. You can only push the distribution as far as a salary you could defend with a straight face. If you want to see the salary-versus-distribution split run against your actual numbers, our individual tax preparation team does exactly that as part of return planning. The savings are genuine. They’re just narrower, more conditional, and more dependent on your specific profit and salary than the headline pitch makes them sound. The short version of the LLC vs S-Corp money question: an S-corp is a self-employment-tax play, nothing more, and it only pays when your profit is high enough to support a reasonable salary with a real distribution left over. Get that one fact straight and you’ll see through most of the hype written about it. Everything else is detail on top of that single lever. And remember the cost side never goes away. Even in a great year, the S-corp savings in the LLC vs S-Corp comparison are the gross self-employment-tax reduction minus the payroll, the separate 1120-S, and the bookkeeping. We always quote clients the net number, not the gross, because the gross is what gets people excited and the net is what actually lands in their pocket. A $6,000 reduction that costs $3,000 to capture is a $3,000 win, full stop, and that’s the figure worth deciding on.

The break-even in the LLC vs S-Corp decision is the profit level where the self-employment tax you save by electing S-corp status finally exceeds the extra cost of running one. As a rule of thumb, that’s somewhere around $80,000 to $100,000 of net profit. Below that band, a default LLC usually wins on total cost. Above it, the S-corp pulls ahead and keeps widening the gap as profit grows. But “rule of thumb” is doing real work in that sentence, because the exact break-even moves with your salary, your state, and your city. There is no universal number, and anyone who quotes you one is skipping the part that matters.

Here’s why the band sits where it does. The savings come from taking part of your profit as a distribution instead of salary, skipping the 15.3% self-employment tax on that slice — 12.4% for Social Security up to the 2026 wage base of $184,500, plus 2.9% for Medicare with no cap. The cost is the $2,000 to $5,000 a year an S-corp adds: payroll processing, Form 941 every quarter, Form 940 once a year, a W-2, a separate Form 1120-S due March 15, and the bookkeeping to support all of it. Break-even is simply the profit level where the first number gets bigger than the second. That’s the whole LLC vs S-Corp calculation, boiled down to one comparison.

Walk it up the ladder with a $50,000 reasonable salary held constant, so you can see the break-even appear. At $60,000 of profit, your distribution is $10,000, saving about $1,530 in self-employment tax — less than the cost of running the S-corp, so you actually lose money electing. At $80,000 of profit, the distribution is $30,000, saving about $4,590. Subtract roughly $2,500 in added costs and you net around $2,000. Thin, but positive. At $120,000 of profit, the distribution is $70,000, saving about $10,700, and the added costs barely register against it. At $200,000 of profit, the distribution is $150,000, saving roughly $20,000 (the Social Security cap of $184,500 starts to factor in around here, but the Medicare piece keeps running on every dollar), and the election is an emphatic yes. The IRS lays out the self-employment tax mechanics that drive every one of those figures, and the S-corporation rules that make the split possible.

The reason there’s no single magic number is that the break-even depends entirely on your reasonable salary, and that’s the variable people forget. If your work commands a $90,000 salary, you need much more profit before there’s a meaningful distribution to save on — your break-even might be $130,000 instead of $90,000. If a defensible salary for your role is only $45,000, you reach break-even sooner. So a contractor and a consultant with identical profit can land on completely different answers to the LLC vs S-Corp question, purely because the going market rate for their labor differs. Anyone who hands you a flat “elect at $X” without first asking what you actually do for a living is guessing, and probably guessing wrong.

Then there’s geography, which is where New York scrambles the standard answer. In New York City, the break-even is higher than the national figure, because the city taxes S-corps under the General Corporation Tax and doesn’t recognize the S election at all, per the NYC Department of Finance. The city’s corporate-level tax claws back part of your federal savings, pushing the profit you need to come out ahead higher than the usual $80,000 to $100,000. New York’s PTET election can offset some of this by recovering federal SALT-cap deductions blocked by the $40,000 cap, but the net effect is that a NYC business should run its own numbers rather than trust a generic threshold built for the rest of the country. The LLC vs S-Corp break-even is a local question dressed up as a national one.

There’s a timing angle to the break-even that owners rarely think about until it bites. The S-corp election generally takes effect for a full tax year, so if your profit only crosses into S-corp territory partway through the year, you’re still carrying the payroll and the separate 1120-S for the whole year. A business that has a breakout fourth quarter and ends up at $95,000 of profit didn’t earn that evenly, and the compliance cost doesn’t prorate. This is part of why we tell clients with lumpy or seasonal income to look at a two- or three-year average rather than a single strong year before committing. The LLC vs S-Corp break-even is a recurring annual test, not a one-time gate you pass once and forget. If next year’s profit drops back under the line, you’re paying for an S-corp that isn’t earning its keep that year.

The practical takeaway on the LLC vs S-Corp break-even: don’t elect on a rule of thumb. Electing too early is the single most common expensive mistake we have to unwind — owners who filed Form 2553 at $45,000 of profit and then spent more on payroll and the second return than they ever saved in self-employment tax. Wait until your profit is steady and clearly past break-even for your specific salary and your specific location, then file. Lumpy profit that crosses the line one year and falls back the next is a reason to wait, not to jump. If you’d like the calculation run on your actual figures, our bookkeeping and tax teams can build the comparison and tell you whether the election pays off this year or whether you’re better off waiting another season. The LLC vs S-Corp break-even isn’t a number you read off a chart. It’s a number you calculate from your own profit, your own defensible salary, and your own state and city, and it can shift from one year to the next. That’s exactly why a quick annual check beats a one-time guess that you never revisit. The last thing worth saying on the break-even: the cost of being wrong is asymmetric. Wait one year too long to elect and you’ve left maybe a few thousand dollars of self-employment-tax savings on the table for that year. Elect a year or two too early and you’ve not only spent more than you saved, you’ve signed up for payroll runs, quarterly filings, and a March 15 corporate deadline that you now carry indefinitely. Given that the LLC vs S-Corp downside of electing too soon outweighs the downside of waiting, when the numbers are genuinely borderline, we lean toward waiting one more season.

You don’t choose between them. This is the single biggest misunderstanding in the whole LLC vs S-Corp debate: an LLC can elect to be taxed as an S-corp, and for most owners that’s exactly the right setup. You keep the LLC as your legal entity and add the S-corp tax treatment on top of it. There’s no need to dissolve anything, form a corporation from scratch, or pick one structure at the expense of the other. The legal wrapper and the tax election are two separate decisions, and they sit on top of each other comfortably. Treating the LLC vs S-Corp choice as either/or is what leads people to waste money they didn’t need to spend.

Here’s how it actually works. Your LLC already exists as a legal entity under your state’s law — in New York, formed by filing Articles of Organization with the Department of State. To change how that entity is taxed, you file Form 2553, Election by a Small Business Corporation, with the IRS. That one form tells the IRS to stop treating your LLC as a disregarded entity or partnership and start taxing it under Subchapter S instead. Your LLC keeps its name, its EIN, its bank accounts, and its contracts — all of it. On paper with the state, nothing changes. Only the federal tax treatment shifts. The legal entity and the tax status are genuinely independent of each other, which is the key insight behind the whole LLC vs S-Corp question.

The timing matters, and it trips people up constantly. To have the S election apply for the current tax year, you generally file Form 2553 within two months and 15 days of the start of that year — so by March 15 for a calendar-year business. Miss that window and the election usually takes effect the following year instead. The IRS does allow late-election relief in many cases if you have reasonable cause and file the right paperwork, and we use that relief fairly often for clients who decided mid-year they wanted S-corp treatment after the deadline passed. It’s fixable. It’s just cleaner, and a lot less paperwork, to file on time and not lean on the relief provisions.

Let me show you why “you don’t have to choose” saves real money, because the LLC vs S-Corp confusion has a price tag. A freelancer formed a single-member LLC two years ago and now clears $140,000 in profit. A well-meaning friend tells them they need to “become an S-corp” to save on taxes, and they almost pay a lawyer $1,500 to dissolve the LLC and incorporate a brand-new entity from scratch. They didn’t need any of that. They file one Form 2553, keep the existing LLC exactly as it is, start running payroll at an $85,000 salary, and take the remaining $55,000 as a distribution — saving roughly $6,500 a year in self-employment tax. Total cost to make the change: one form and a payroll setup. The LLC they already had did all the legal work. The election did all the tax work. The lawyer and the dissolution were a solution to a problem that never existed.

There’s a state wrinkle in New York worth flagging on top of the federal election. The federal Form 2553 handles the IRS, but New York requires a separate state S election on Form CT-6, filed with the New York State Department of Taxation and Finance. File the federal one and forget the state one, and New York taxes your LLC as a C-corporation at the state level — a common and entirely avoidable error that we fix for new clients all the time. And remember, New York City won’t recognize the S election no matter what you file, taxing the entity under the General Corporation Tax regardless of your federal and state elections. So in the city, the LLC vs S-Corp math has a third moving part the rest of the country never deals with, and it pays to have someone track all three.

It’s worth clearing up one related point, because it confuses people in the LLC vs S-Corp conversation. Electing S-corp status does not turn your LLC into a corporation in any legal sense. You don’t suddenly owe annual corporate minutes, a board of directors, or shareholder meetings under corporate law, because your entity is still an LLC governed by your operating agreement and your state’s LLC statute. The “S-corp” label is purely a federal tax classification. That’s actually one of the quiet advantages of running an LLC with an S-election instead of forming an actual corporation and electing S status: you get the salary-and-distribution tax treatment while keeping the lighter governance and flexibility of an LLC. Same tax result, less corporate formality. For most solo owners and small partnerships, that combination is the sweet spot, which is why it’s the setup we recommend most often once the numbers justify the election.

So the answer is clean: an LLC electing S-corp taxation is not only allowed, it’s the standard path for owners past the break-even. You’re not giving up your LLC, and you’re not trading one structure for another. You’re giving the same entity a different tax coat. The IRS guidance on LLCs confirms that an LLC can choose corporate, including S-corporation, tax treatment without changing its legal form. If you want help deciding whether to make the election and filing the forms correctly at both the federal and New York level, our entity formation and structuring team does this regularly and will make sure the IRS, the state, and the city paperwork all line up the way it should. So treat the LLC vs S-Corp choice for what it really is: not a fork in the road where you give up one path to take the other, but a tax setting you can switch on top of the LLC you already have, when and only when the numbers say it’s worth it. Keep the entity. Add the election when it earns its place. That sequencing is what saves the money and avoids the wasted legal fees.

Yes — and this is the part of the LLC vs S-Corp tradeoff that the savings pitch almost always skips over. The moment your LLC elects S-corp status, you take on real compliance work that a default LLC never has to deal with. Two things in particular: you have to run actual payroll for yourself, and you have to file a separate business tax return every single year. Neither is optional, and both cost money. This is exactly why the election doesn’t pay off below a certain profit level. The compliance burden is fixed, so the S-corp side of the LLC vs S-Corp comparison only wins once your tax savings clearly outrun it.

Payroll first. As an S-corp owner who works in the business, you’re now an employee of your own company, and you have to pay yourself a reasonable salary through formal payroll. That means withholding income tax, Social Security, and Medicare from your paychecks, remitting those withholdings to the government on schedule, and filing Form 941 every quarter to report federal payroll taxes. Once a year you also file Form 940 for federal unemployment tax, and you issue yourself a W-2 each January, the same form any employer hands any employee. Most owners don’t do this by hand. They pay a payroll service a few hundred dollars a year to run it, file the forms, and keep the deadlines straight. And to be clear, you can’t just move money from the business account to your personal account and call it salary. The IRS wants the actual payroll machinery with the actual filings behind it.

Then the separate return, which is the other half of the LLC vs S-Corp compliance jump. An S-corp files its own Form 1120-S every year, and the deadline is March 15 — a full month before your personal Form 1040 is due on April 15. That earlier deadline catches people off guard their first year as an S-corp, because they’re used to thinking April. The 1120-S reports the business’s income and expenses and generates a Schedule K-1 for you, which carries your share of the profit over to your personal return. So you’ve gone from filing one return to filing two, and the business one comes due first. Miss the March 15 deadline and the late-filing penalty stacks per shareholder per month, which adds up fast even for a one-owner S-corp where you’re the only shareholder.

There’s a bookkeeping requirement hiding inside all this too. An S-corp needs clean books — a real balance sheet, tracked basis, documented distributions, and a clear record of the salary-versus-distribution split in case the IRS ever asks how you arrived at your numbers. The IRS reasonable-compensation guidance is the reason that documentation matters: if you can’t show how you set your salary, an auditor can set it for you. A default single-member LLC can sometimes get by on loose records and a Schedule C cobbled together at year-end. An S-corp can’t. If your books are currently a shoebox of receipts and a bank app, the cost and effort of getting them into real shape is part of the price of the election, and it’s a part people forget to budget for.

Here’s the math that makes the point concrete. Suppose your LLC clears $70,000 in profit and a reasonable salary for your work is $55,000. Elect S-corp status and your distribution is only $15,000, saving about $2,300 in self-employment tax for the year. But now you’re paying maybe $600 a year for payroll, $1,200 or more for the separate 1120-S return, and a few hundred for the cleaner bookkeeping — call it $2,500 in added cost. You spent $2,500 to save $2,300. You went backward. That’s the mistake we see constantly in the LLC vs S-Corp decision: owners who elected for the tax savings without accounting for the compliance bill, and ended up paying more than they saved while also signing themselves up for quarterly filings they now have to track forever.

One practical warning we give every new S-corp client, because it’s the cash-flow surprise that catches first-timers. When you run payroll, the tax money leaves your account throughout the year as withholding and payroll deposits, instead of sitting in your business account until you scramble to pay it at filing time. That’s actually healthier discipline, but it feels different, and you have to plan for it. You also can’t skip a quarter because money is tight. The Form 941 filing and the deposits are due on the IRS schedule whether or not you ran a profitable quarter. So part of saying yes to the S-corp side of the LLC vs S-Corp decision is committing to a steadier, more structured cash rhythm than a default LLC owner who just sweeps profit whenever they want. If your income is erratic enough that making payroll on schedule would be a strain, that’s a real mark against electing, separate from the pure tax math.

So plan for the work, not just the savings. If the numbers clearly justify it — generally once profit is comfortably past $80,000 to $100,000 for your salary level, and higher than that in New York City because of the General Corporation Tax — then the payroll and the second return are a fair price for the self-employment tax you’ll save year after year. If they don’t, staying a default LLC keeps your life simpler and your costs lower, and there’s no shame in that. The LLC vs S-Corp choice isn’t about prestige, it’s about whether the savings beat the bill. Our business management team handles the payroll, the 1120-S filing, and the bookkeeping for S-corp clients, so if you do elect, the compliance side gets run for you instead of landing on your desk every quarter and every March. If you’d like us to run the LLC vs S-Corp numbers on your actual profit and tell you whether to elect this year, start a new client inquiry and we’ll take it from there.
