Worked example
A sole proprietor couple pays their 12-year-old $12,000 in 2026
These are the calculator's prefilled defaults: a married couple filing jointly with $200,000 of taxable income from a sole proprietorship pays their child, who is under 14, $12,000 of W-2 wages for real work. The parents are under the Social Security wage base.
Inputs
| Tax year | 2026 |
|---|---|
| Parent filing status | Married filing jointly |
| Parent taxable income (before paying child) | $200,000 |
| W-2 wages to child | $12,000 |
| Child age | Under 14 |
| Business type | Sole prop / single-member LLC |
| Parent over the Social Security wage base | No |
Calculator output
| Parent marginal rate | 22.0% |
|---|---|
| Income tax saved | $2,453 |
| SE tax saved | $1,696 |
| Payroll taxes added | $0 |
| Child's tax | $0 |
| Net federal savings (estimate) | $4,149 |
The child is under 18 and the business is a sole proprietorship, so no Social Security or Medicare tax applies to the wages. The parent's self-employment tax drops by 15.3% of 92.35% of the $12,000, or $1,696. The $12,000 deduction comes off income taxed at 22%, less the $848 drop in the parent's deduction for half of SE tax, so it is worth $2,453 of income tax. The child's wages fall under the 2026 standard deduction, so the child owes no federal income tax. This is an illustration of the math, not a promised result.
