The S-Corp $80k Threshold Is a Lie

There's no magic $80,000 line. Whether an S-corp election pays depends on two things the rule of thumb never mentions: the salary you pay yourself, and the income tax that salary changes through the QBI deduction. At a 60% salary and the other default assumptions of our S-Corp Savings Calculator, it pays off between $57,263 and $222,474 of net profit, and again from $263,978 — above $222,474, the salary is still paying Social Security tax after a sole proprietor's has stopped at the wage base; from $263,978, the QBI wage limit takes the deduction from a sole proprietor with no payroll, and the salary keeps it. Below $263,978 of net profit, it never saves more than about $1,934 a year at these assumptions. At $80,000 itself, the election saves about $528 a year.

If you have any 1099 income, you have almost certainly run into the number: "Once you hit $80,000 in net self-employment income, elect S-Corp."

It's repeated everywhere — Reddit, Twitter, every solopreneur blog. The number sounds precise, almost official. It isn't. This article walks through where it comes from, what it leaves out, and why the salary you'd actually pay yourself matters more than any single income figure.

Where the $80k number comes from

The rule of thumb prices payroll tax alone. As a sole proprietor or single-member LLC you pay self-employment tax of 15.3% on 92.35% of your profit. As an S-corp you pay the same rate on your salary only, so the saving is the tax on the part of profit you take as distributions — and it has to cover what the S-corp costs to run.

Priced that way, at a 60% salary and with $2,500 a year of overhead, the election starts paying at $50,510 of net profit. The popular napkin version comes out lower still, because it charges self-employment tax on all of your profit instead of 92.35% of it.

So why does everyone say $80k? Partly because a salary at that share of profit only looks defensible once profit is high enough that the salary still reads as market pay on its own. And partly because the payroll-only math leaves out the other half of the answer.

What the napkin math leaves out: income tax

The 20% QBI deduction is figured on qualified business income, and an S-corp owner's salary is not qualified business income. Below the QBI threshold ($201,750 of taxable income for a single filer in 2026), electing shrinks the deduction, and your income tax goes up.

At $150,000 of net profit, electing S-corp saves about $1,286 a year. It saves $7,424 of payroll tax, against $2,500 of overhead and $3,639 more federal income tax (the salary cuts your QBI deduction from $24,661 to $10,123).

Above the threshold the salary works the other way. A business that isn't a specified service business can take the deduction only up to a limit set by the W-2 wages it pays; a sole proprietor with no payroll pays none, and your salary counts. At $308,500 of profit the deduction is $400 as a sole proprietor and $21,477 as an S-corp, and the election saves about $8,861 a year.

The "reasonable salary" question is everything

The IRS rule: S-Corp owners must pay themselves reasonable compensation for the work they actually perform — meaning what you'd pay an outside hire to do your job. The rule has no precise formula, but the IRS has won most challenges where owners paid themselves dramatically below market wages.

Here is what the salary share alone does, with every other assumption held at the calculator's defaults (a single filer with no other income, the standard deduction, and $2,500 a year to run payroll and file the extra Form 1120-S return — our own planning estimate, not a quote):

At a 50% salary, it starts paying off at $37,710 of net profit. At 70%, it starts paying off at $282,215 of net profit.

So if you're a freelance designer whose defensible salary is most of what you net, the election may not pay at your income at all. If your profit has outgrown what the role would pay an outside hire, the salary can defensibly be a smaller share of it — and that, not a fixed income line, is when the arithmetic starts to work.

The hidden costs everyone underestimates

Here's what an S-Corp actually costs:

• Payroll service: a subscription you pay every month, forever. Required to actually run yourself a real W-2 paycheck.
• Form 1120-S preparation: a second return, filed every year on top of your 1040. More complex than Schedule C, and priced accordingly.
• State entity tax: nothing extra in most states, but not everywhere. California taxes an S-corp's net income at 1.5%, with a minimum of $800 a year — but an LLC that elects stops paying the $800 annual LLC tax and the receipts-based LLC fee, so this calculator counts only the difference.
• Bookkeeping: hours of your time each month, or what it costs to hand that off. Required to keep books that separate salary from distributions.
• A smaller QBI deduction: below the QBI threshold, the salary comes out of the income the deduction is figured on. Every figure in this post already counts it.
• Lost retirement room (sometimes): a Solo 401(k)'s employer contribution is figured on your W-2 salary as an S-corp, and on net self-employment earnings as a sole proprietor — so a lean salary can shrink your tax-deferred space.

Get real quotes before you elect. The figures in this post assume $2,500 a year to run payroll and file the extra Form 1120-S return — our own planning estimate, not a quote; if your own quotes come in higher, every breakeven above moves up with them.

The 5-year lock-in nobody mentions

Here's the part that surprises people: once you elect S-Corp and revoke, the IRS won't let you re-elect for 5 years. So if you elect in a strong year, business slows for two years, and you revoke to save the admin — you're stuck without the option for 5 years even if income recovers.

For income that fluctuates significantly year-to-year (most freelancers and consultants), this is a real cost. Sole prop / single-member LLC has no commitment. S-Corp commits you to years of admin overhead unless you want to give up the option entirely.

The actual decision framework

Three criteria to clear before electing:

1. Sustained profit where the election is worth the admin — at the salary you'd actually pay, and not one good year: a few years of trajectory.
2. A defensible salary that's well below your net income — meaning your role isn't pure billable hours where the IRS will argue all of it is wages. Software engineers, designers, consultants, content creators: usually defensible. Real estate agents, sales pros: often harder.
3. You're committed to the admin overhead — payroll service, separate bank account, real W-2 paychecks. If the answer is "I'll figure it out," you'll forget a quarterly payroll deposit and the IRS will disallow your distribution treatment retroactively.

Use the calculator

The S-Corp Savings Calculator uses a 60% salary and counts both the payroll tax the election saves and the income tax the salary changes. Compare its number against the admin cost you were actually quoted — not the $2,500 it assumes — and against the salary you'd really pay yourself.

The bottom line

The $80k threshold is a directional rule of thumb, not a cutoff. At a 60% salary and this site's default assumptions:

• Below $57,263: it costs more than it saves.
• From $57,263 to $222,474: it saves at most about $1,934 a year.
• From $222,475 to $263,977: it costs more than it saves again.
• From $263,978 up: it saves money — about $6,626 a year at $300,000.

The election is also semi-permanent (a 5-year wait to re-elect after revoking), so don't make it on one good year. Wait for the trend.
