What 1099 Income Really Costs in Tax
- Self-employment tax (SS + Medicare, both halves)$11,30414.1%
- Federal income tax$5,3446.7%
- Take-home pay$63,35379.2%
A 1099 contractor pays 15.3% in payroll tax instead of 7.6% — there is no employer to pick up the other half. But that headline rate is wrong in both directions: the tax is charged on 92.35% of your net income, half of it is deductible, and the QBI deduction takes 20% off the income tax base. This index shows the resulting bill at every income level, plus what the same gross would have been as a W-2 employee.
By income level
Net self-employment income before business expenses, single filer, standard deduction, full 20% QBI. "Keeps" is what is left after both taxes.

The four steps everyone skips
1. The 92.35% base. Self-employment tax is computed on 92.35% of net earnings, not on the full amount. The missing 7.65% represents the employee-side FICA the law treats as already deductible. On $50,000 that alone removes $3,825 from the base.
2. You pay both halves. 12.4% Social Security + 2.9% Medicare. The employer half does not disappear because you became your own employer; you are it now.
3. Half is deductible, but not as a credit. Half of self-employment tax reduces adjusted gross income, which in turn reduces income tax. Treating it as a credit (subtracting it directly from the tax) overstates the benefit.
4. QBI, then the brackets. The 20% qualified business income deduction is applied after the half-tax deduction and the standard deduction, and it is capped at 20% of taxable income before it. Applying it to gross income inflates the deduction.
1099 vs W-2 at the same gross
A job paying $75,000 and a contract paying $75,000 are not the same offer. The gap below is the employer half of payroll tax plus the income-tax difference the deductions create — before counting benefits, tools, or unpaid time.
| Gross | 1099 keeps | W-2 keeps | Freelance premium needed |
|---|---|---|---|
| $40,000 | $32,573 | $34,320 | $9,120 |
| $45,000 | $36,421 | $38,338 | $10,601 |
| $50,000 | $40,268 | $42,355 | $12,084 |
| $55,000 | $44,115 | $46,373 | $13,570 |
| $60,000 | $47,963 | $50,390 | $15,058 |
| $65,000 | $51,810 | $54,408 | $16,548 |
| $70,000 | $55,658 | $58,075 | $18,038 |
| $75,000 | $59,505 | $61,593 | $19,530 |

| $100,000 | $77,635 | $79,180 | $28,807 |
| $110,000 | $84,587 | $86,215 | $33,048 |
| $120,000 | $91,538 | $93,250 | $37,311 |
| $130,000 | $98,490 | $100,121 | $41,592 |
| $140,000 | $105,441 | $106,956 | $45,886 |
| $150,000 | $112,392 | $113,791 | $50,192 |
| $175,000 | $129,540 | $130,879 | $61,413 |
| $200,000 | $146,569 | $148,927 | $72,908 |
| $250,000 | $185,508 | $183,182 | $86,913 |
The last column is the extra invoice volume needed just to match the W-2 take-home at the same tax structure — the rough "20–30% contractor premium" people quote comes from this arithmetic, not from a rule of thumb.
Quarterly estimates are not optional
There is no withholding on 1099 income, so the IRS expects four payments a year. The amounts above divide cleanly into four, but the two safe harbors are what actually decide whether a penalty applies: pay 100% of last year's tax (110% if AGI exceeded $150,000), or 90% of this year's.
What this index does not model
State income tax, self-employment health insurance, retirement contributions, the QBI phase-out above $201,775 of taxable income for service businesses, S-corp elections, and the home-office and mileage rules. Each of those moves the answer by hundreds to thousands of dollars; the per-income pages say which ones are missing rather than quietly assuming zero.
Questions
Is all 1099 income subject to self-employment tax?
Net income after ordinary business expenses, yes. The threshold is $400 of net self-employment income — below that there is no self-employment tax, but the income is still reportable.
Why is my effective self-employment tax lower than 15.3%?
Because the base is 92.35%, which already makes the effective rate about 14.13% of gross, and because Social Security stops at $184,500 while Medicare continues. High earners see the combined rate fall well below 15.3%.
Does a 1099 contractor get the standard deduction?
Yes — business expenses come off on Schedule C first, then the standard deduction applies to the resulting income like anyone else's. The two are not alternatives.
