What this model assumes
- General nonfarm Schedule SE method for one individual. Net earnings are 92.35% of net profit; the regular $400 filing threshold is applied.
- Your Social Security wages exclude your spouse’s wages. For a joint return enter both spouses’ Medicare wages, but this simplified model assumes only the individual has self-employment earnings.
- Additional Medicare shown is the incremental tax on these self-employment earnings, not the separate tax on wages. It is not deductible as half of SE tax.
- Excludes optional methods, church/ministry rules, exempt earnings, railroad compensation, totalization agreements, income taxes, and state taxes.
