What South Dakota does differently
South Dakota levies no personal income tax, so the entire question here is federal. The election saves payroll tax on the distribution and nothing else, there is no state layer for it to move, and no state return for the S-corp's owners to reconcile.
The South Dakota detail
South Dakota has no personal or corporate income tax for ordinary businesses, so an S corporation owes no state income tax, no entity-level charge and no minimum. The recognition question is effectively moot here. A bank franchise tax exists but reaches financial institutions only, which is the single thing to check before assuming this page applies to you: if you run a bank, a trust company or certain lenders, you are in a different regime with its own rates. For everyone else the only recurring cost is the annual report, $55 filed electronically or $70 on paper.
How much salary to pay yourself
Enter your figures above and press Calculate.
Less salary means less payroll tax, so the arithmetic always points at the smallest salary you can justify. That is exactly why it is not a number to optimize: compensation has to be reasonable for the work you do, and the penalty for getting it wrong is reclassification plus back payroll tax. The cheapest row here is the riskiest one.
| Salary share | Salary | Distribution | Total tax | vs sole proprietor |
|---|---|---|---|---|
| 20% | $20,000 | $76,970 | $13,543 | $8,821 |
| 30% | $30,000 | $66,205 | $15,345 | $7,019 |
| 40% | $40,000 | $55,440 | $17,147 | $5,218 |
| 50% | $50,000 | $44,675 | $18,949 | $3,416 |
| 60% | $60,000 | $33,910 | $20,750 | $1,614 |
What this assumes
- Single filer, standard deduction, the business as the only income.
- 40% of profit taken as salary in the headline figures.
- $1,500 a year for payroll and a separate 1120-S, a cost estimate, not a tax figure, and it varies by provider.
- Comparing against a sole proprietorship. If you already trade through an LLC, some state fees are owed either way and are not a cost of electing.
- Anything listed as not modeled above is genuinely owed, it is excluded because it does not depend on profit, not because it is nil.
What these words mean
- Franchise tax
- A charge for the privilege of operating as a company in a state. Despite the name it has nothing to do with franchises, and it is often owed whether or not the business made money.
- Entity level
- A tax charged to the company itself, before any profit reaches the owners, as opposed to a tax the owners pay on their own returns.
- S corporation election
- Asking the tax office to treat your company as a pass-through, so profit is taxed to you rather than to the company. The owner takes a salary and the rest as a distribution, which is what saves payroll tax.
- Distribution
- Profit paid out to a company’s owner that is not salary. It is not subject to payroll or self-employment tax, which is the whole point of the S corporation election. And why the salary has to be defensible.
