Estimate the self-employment tax savings from electing S-corporation tax treatment for your LLC. Below the snapshot table you'll find the break-even income range and the payroll compliance cost that offsets the SE tax savings.
Use last year's Schedule C net income or your forecast for the current year. The calculator splits that figure into a reasonable-salary portion, which stays subject to payroll tax, and a remainder taken as distributions, which escapes self-employment tax under S-corp treatment. The size of that distribution portion is where the tax saving lives, so an accurate net-income figure drives an accurate estimate.
The IRS requires an S-corp owner-employee to draw a reasonable salary for the work performed before taking distributions. The rule-of-thumb starting point is 40 to 60 percent of net income, calibrated to industry comparables from sources like BLS wage data and RC Reports. A salary set too low to inflate the tax-free distribution invites IRS reclassification, which recaptures the saved payroll tax and adds penalties and interest.
The tool computes self-employment tax under the default LLC classification, then computes payroll tax on the salary portion under S-corp treatment, subtracts about $1,500 per year in payroll compliance cost, and reports the net saving. The compliance cost covers a payroll service and the extra tax filings an S-corp requires. Net saving, not gross tax difference, is the number that decides whether the election is worth it.
The tool returns one of three verdicts: stay in the LLC default, treat the case as marginal, or elect S-corp. Below roughly $40,000 of net income the compliance cost outweighs the saving; between $40,000 and $60,000 the answer depends on industry and reasonable-salary latitude; above $60,000 the election pays off. The verdict pairs with a dollar figure so the tradeoff is concrete.

2026 Social Security wage base: $168,600. Additional Medicare 0.9% above $200,000 single. Assumes $1,500/yr payroll compliance cost. IRS requires a "reasonable salary" - too low risks reclassification. Not tax advice; consult a CPA.

Assumes 15.3% SE tax up to $168,600 SS wage base + 2.9% Medicare above. S-corp scenario assumes $1,500/yr payroll compliance cost subtracted from gross SE savings. 'Reasonable salary' is a rule-of-thumb estimate; actual depends on industry, role, and locale per IRS reasonableness test. Not tax advice - consult a CPA.
S-corp election pays off once net business income clears $40,000 to $60,000 per year. Below that band the roughly $1,500 annual payroll compliance cost eats the self-employment tax saving; above it the saving wins. Inside the band the answer turns on industry norms and how much room you have to set a defensible reasonable salary. Above $60,000 the election reliably produces net savings, which grow with income. Above the $168,600 Social Security wage base the 12.4 percent Social Security portion caps out, so the biggest incremental savings taper, but the 2.9 percent Medicare saving on the distribution portion continues on every dollar.
A reasonable salary is the wage an S-corp owner-employee must pay themselves for the work they perform before taking tax-favored distributions. Setting it too low is the single biggest audit risk in the whole strategy. The IRS tests reasonableness against industry comparables, time devoted to the business, and role complexity. A salary set artificially low to enlarge the distribution portion invites reclassification of those distributions as wages, which recaptures the saved payroll tax and adds penalties and interest. The 40-to-60-percent guideline is a starting point, not a safe harbor; calibrate it against BLS wage data or an RC Reports study for your role and locale.
You elect S-corp treatment by filing IRS Form 2553. An existing entity files by March 15 to apply the election to the current tax year; a new entity has 75 days from formation. After the election, the LLC files Form 1120-S each year and issues Schedule K-1s to its members, and the owner has to run real payroll to pay the reasonable salary. Payroll services such as Gusto or ADP run $40 to $80 per month. A missed Form 2553 deadline can still qualify for late-election relief under Rev. Proc. 2013-30 when the entity meets the reasonable-cause conditions.
No. The entity remains an LLC under state law after an S-corp election. Only the federal tax classification changes. The liability shield, the operating agreement, the registered agent, and the Secretary of State records all stay exactly as they were. S-corp is a tax election layered on top of the LLC, not a conversion to a corporation. That means an anonymous LLC keeps its anonymity and its charging order protection while gaining the payroll-tax treatment, so the privacy and asset-protection features of the formation state are untouched by the election.
No. S-corp shareholders must be US citizens or resident aliens, so a non-US-resident owner cannot elect S-corp treatment. The default pass-through or a C-corp election are the available paths. A C-corp election is open to non-residents but introduces a 21 percent corporate tax plus 30 percent withholding on dividends paid to the foreign owner, which costs more than it saves for most small businesses. Non-resident owners who want to reduce US tax focus instead on whether their income is effectively connected to a US trade or business, since income that is not effectively connected escapes US income tax without any election.
The estimate covers federal self-employment and payroll tax only. It leaves out federal and state income tax, the qualified business income deduction, and state-level payroll or franchise obligations. Some states tax S-corp income differently from pass-through income, and a few impose an entity-level tax that erodes the federal saving. The estimate also assumes a flat $1,500 payroll compliance cost, which varies with provider and filing complexity. Treat the output as a decision guide for the payroll-tax question, then confirm the full picture, including income tax and state rules, with a CPA before filing Form 2553.
