Question 1

What is an S-corporation election and how does it save self-employment tax?

Accepted Answer

An S-corporation election (IRS Form 2553) lets an LLC or corporation pass income through to the owner while splitting it into two streams: a reasonable W-2 salary subject to payroll tax, and distributions that are not subject to self-employment tax. By contrast, all net profit of a sole proprietorship or single-member LLC is subject to the 15.3% self-employment tax up to the Social Security wage base.

Question 2

At what profit level does an S-corp election typically make sense?

Accepted Answer

The math typically works once annual net profit clears roughly $50,000 to $80,000, after accounting for the added costs of running payroll, a separate corporate tax return, and state-level S-corp fees (commonly $1,000 to $3,000 a year combined). Below that range, the added costs often eat the tax savings.

Question 3

What is reasonable compensation for an S-corp owner?

Accepted Answer

Reasonable compensation is what the business would pay an unrelated party to do the same work. The IRS evaluates training and experience, duties and responsibilities, time and effort devoted to the business, comparable salary data, and the company's overall financial condition. Setting the salary too low invites IRS reclassification and back payroll tax; setting it too high erases the S-corp tax savings.

Question 4

What rates does the calculator use?

Accepted Answer

The calculator uses 2026 estimated federal income-tax brackets, the 2026 Social Security wage base of $176,100, the 15.3% self-employment tax (12.4% Social Security plus 2.9% Medicare) with the 0.9% Additional Medicare Tax above $200,000 single / $250,000 MFJ, and the top income-tax rate for the state you select.

Question 5

How does an S-corp election change federal income tax?

Accepted Answer

It does not change federal income tax on profits already in the owner's pocket. The savings come exclusively from removing the self-employment tax on the distribution portion of the income. Owners still pay federal income tax on the full pass-through profit at their marginal rate.

Question 6

Does the calculator work for Idaho residents?

Accepted Answer

Yes. Idaho applies a flat 5.3% to the same taxable income the federal model produces, so the calculator's federal logic carries cleanly into Idaho. Other states layer in their own brackets, which the calculator applies based on the state you select.

Question 7

Is this calculator a substitute for tax advice?

Accepted Answer

No. The calculator estimates self-employment tax savings under a reasonable-comp scenario. It does not evaluate the full picture: entity formation costs, payroll setup, additional tax-return complexity, state-specific S-corp fees, retirement-plan implications, qualified business income deduction interactions, and multi-state issues all matter. Vantage Advisors evaluates those tradeoffs as part of its advisory tiers.
