The 92.35% adjustment accounts for the employer-equivalent portion of SE tax.
| Component | Rate | Applies to |
|---|---|---|
| Social Security | 12.4% | Up to annual wage base |
| Medicare | 2.9% | All net SE income |
| Additional Medicare | 0.9% | Income above threshold |
So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.
Worked example: $80,000 net freelance income
| Step | Calculation | Amount |
|---|---|---|
| Net SE income | — | $80,000 |
| SE tax base (× 92.35%) | $80,000 × 0.9235 | $73,880 |
| SE tax (× 15.3%) | $73,880 × 0.153 | $11,304 |
| Deductible half of SE tax | $11,304 ÷ 2 | $5,652 |
| Federal income tax (est.) | On ~$74,348 AGI | ~$10,000 |
| Total estimated tax | — | ~$21,300 |
Set aside 25–35% of net income for combined federal, state, and SE taxes.
So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.
Quarterly estimated payment schedule
| Quarter | Income period | Due date |
|---|---|---|

| Q2 | Apr 1 – May 31 | June 15 |

| Q4 | Sep 1 – Dec 31 | January 15 |
Underpayment triggers penalties — pay at least 90% of current year tax or 100% of prior year tax (110% if high income).
So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.
