How Much Does an S-Corp Cost to Run? The Real Annual Price in 2026

The designer above is a composite, not an actual EntityIQ client, and every number below is a theoretical 2026 figure rounded for readability. But the cost stack is real, and it is the part most calculators skip. An S-Corp election lowers the self-employment tax on the profit you take as distributions. It does not lower it on the salary you have to pay yourself, and it comes with a payroll and filing burden that a sole proprietor never touches. The question is never just "how much will I save." It is "how much will I save after the cost of the election."

What the election actually changes

As a sole proprietor or single-member LLC, you report business profit on Schedule C of your Form 1040 and pay self-employment tax under IRC §1401. That tax is 15.3% (12.4% Social Security plus 2.9% Medicare) on 92.35% of your net earnings, with the 92.35% multiplier set by IRC §1402(a)(12). There is no separate business return and no payroll.

After you elect S-Corp status, the business files its own return, Form 1120-S, and you become its employee. An owner who works in the business has to be paid reasonable compensation as W-2 wages before taking distributions. The IRS has held this position since Rev. Rul. 74-44, and it is the single most litigated S-Corp issue. Running payroll means filing Form 941 each quarter, Form 940 once a year for FUTA, and issuing a W-2. A sole proprietor files none of that, so the payroll stack is a genuine new cost the election creates.

The cost stack, line by line

The employer half of FICA, 7.65% of wages, is not a new cost. As a sole proprietor you already pay both halves of that same 15.3% through self-employment tax on your profit. The S-Corp just relabels part of it as employer FICA on your salary. The real savings come from the distribution portion, which carries no FICA or self-employment tax at all, and the real costs are the compliance items, not the payroll tax on the wages you were always going to owe. Here is what those compliance items run.

A word on the small federal item. FUTA is set by IRC §3301 at 6.0% on the first $7,000 of each employee's wages, with the $7,000 base fixed by IRC §3306(b)(1). Nearly every employer earns the full 5.4% state credit under IRC §3302, which drops the effective rate to 0.6%, or $42 per employee per year. It is small, but a sole proprietor pays zero FUTA on their own earnings, so it belongs on the list. One relief for the smallest S-Corps: if total receipts and total assets are each under $250,000, the 1120-S skips the balance sheet on Schedule L and the reconciliations on Schedules M-1 and M-2, per the Form 1120-S instructions, which keeps the bookkeeping lighter.

Two theoretical owners, same cost, opposite result

The cost stack is roughly fixed. The savings scale with profit. That is why the same $2,000 in annual cost is trivial for one owner and fatal for another. Both owners below have no other W-2 job, so every profit dollar is exposed to self-employment tax. The figures are payroll-tax only. Income tax and the §199A QBI deduction move separately.

Owner A saves about $11,249 in payroll tax before costs, because $85,000 of profit moves out of the 15.3% base as distributions. After roughly $1,900 in payroll, 1120-S, and filing costs, she keeps about $9,349. Owner B saves only $2,416 before costs, because her smaller distribution shelters less. California layers an entity-level 1.5% S-Corp tax on net income with an $800 minimum franchise tax on top of the federal compliance stack. On a small profit, that $800 floor alone can wipe out the payroll-tax savings. A theoretical owner with $55,000 of profit who saves about $2,416 in payroll tax can end the year a few hundred dollars behind once the $800 California minimum and the payroll and 1120-S costs are counted. The $800 minimum and 1.5% rate come straight from California's Franchise Tax Board.

The break-even point

There is no single number, but the election tends to go underwater below roughly $40,000 to $50,000 of net profit. Below that, the payroll-tax savings on a modest distribution are small enough that a $1,500 to $3,000 annual cost stack eats most or all of them. Above about $80,000 of profit with no other high W-2 wages, the savings usually clear the cost several times over. For a single-owner S-Corp, the recurring cost usually lands between $1,500 and $3,000 a year. That covers payroll processing for one employee, the premium a preparer charges for a separate Form 1120-S on top of your Form 1040, federal unemployment tax capped at $42, state unemployment tax, and whatever annual report or franchise fee your state charges. High-fee states push the total higher, and a reasonable compensation study, if you buy one, adds a few hundred dollars more.

Two factors shift the line. A high salary requirement in your field shrinks the distribution that generates the savings, which pushes break-even higher. And a high W-2 job outside the business can erase most of the benefit, because your other wages may already have carried you past the $184,500 Social Security wage base, leaving only the 2.9% Medicare slice to save on. I walk through that trap in the guide on the Social Security wage base and S-Corp savings.

Do not decide from a rule of thumb. Run your own profit, your own salary, and your own state through a calculator that accounts for all of it, like the EntityIQ S-Corp tax calculator, and see where you land after costs. For the profit threshold in more detail, see the S-Corp break-even income guide, and for the salary side, the reasonable compensation guide.
