## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability s-corp-reasonable-salary-employment-tax-savings-calculator-2a7c9322 -d '<json body>'
```

Example prompt: I'm filing as single and my S-corp has $180,000 in business profit this year — how much would I save on employment taxes if I set my reasonable salary at $75,000 and take the rest as a distribution?

## When to prefer this

Use this endpoint when you need a fast, focused calculation of the employment tax savings from the S-corp reasonable salary strategy — specifically the difference between SE tax on full sole-proprietor profit versus FICA on an S-corp salary plus a tax-exempt distribution. Prefer this over a full tax estimator when the user only wants to understand the payroll tax arbitrage of the S-corp election, not their complete federal/state income tax picture.

## Known failure modes

- reasonableSalary exceeds businessProfit — logically invalid split, may return zero or negative savings
- businessProfit or reasonableSalary below 0 or above maximum — validation error
- Missing required businessProfit or reasonableSalary fields — 422 or 400 error
- Invalid filingStatus value outside enum — schema validation failure
- Very low salary relative to profit may be flagged as outside IRS reasonable compensation norms (informational, not blocking)

## How this service works

S-corp reasonable-salary employment-tax saving: SE tax a sole proprietor pays on all profit vs FICA an S-corp pays on just the salary, with the distribution that escapes self-employment tax.

## Output

Returns a breakdown comparing total self-employment tax owed as a sole proprietor (on all profit) versus FICA taxes owed as an S-corp (on the salary portion only), the distribution amount that escapes self-employment tax, and the net employment tax savings from the S-corp structure.
