Private contractors typically keep somewhere between 60% and 67% of their gross billings once self-employment tax, federal and state income tax, and ordinary business costs are paid. On gross earnings that run from roughly $45,000 to well over $200,000 a year depending on the field, that take-home share is what actually lands in your bank account. The question of how much private contractors make after taxes comes down to three moving parts: the 15.3% self-employment tax that replaces an employer’s payroll contribution, the regular income tax that applies to whatever is left, and the deductions and retirement contributions that pull the taxable base back down.
A Worked Example From Gross to Take-Home
Picture a technology contractor who bills $150,000 across the year. After $20,000 in business expenses, net self-employment income is $130,000. Self-employment tax on that figure runs about $18,400 (92.35% of $130,000, taxed at 15.3%). Federal income tax applies on top, though the deduction for half of the self-employment tax, the qualified business income deduction, and any retirement contributions all shrink the taxable base before the brackets are applied. After federal and state income tax, this contractor is likely to keep somewhere between $90,000 and $100,000.
That is the pattern across most independent work: gross billings look generous, but roughly a third of them belong to taxes and overhead before you spend a dollar on yourself.
Why Self-Employment Tax Takes the First Bite
The single biggest tax difference between a contractor and a W-2 employee is that you pay both halves of Social Security and Medicare yourself. Under 26 U.S.C. ยง 1401, the combined self-employment tax rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.1Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax
A handful of rules shape what you actually owe:
- The tax applies only once your net earnings reach $400 for the year.2Office of the Law Revision Counsel. 26 USC 1402 – Definitions
- It is calculated on 92.35% of net self-employment income, not the full amount, because employers do not pay payroll tax on their own share of FICA.3Internal Revenue Service. Topic No. 554, Self-Employment Tax
- The 12.4% Social Security portion applies only to the first $184,500 of combined wages and self-employment income in 2026. Earnings above that cap are taxed only at the 2.9% Medicare rate.4Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet
- An extra 0.9% Medicare surtax applies to self-employment income above $200,000 for single filers or $250,000 for married couples filing jointly.1Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax
A solo contractor netting $100,000 after expenses owes roughly $14,130 in self-employment tax alone, before any income tax is calculated.
Typical Gross Earnings by Field
Where you fall inside the $45,000 to $200,000-plus band depends heavily on the work.
In technology, a general freelance programmer averages around $85,000 a year, with top earners above $100,000. Specialists in penetration testing, cloud-security architecture, and AI can bill above $150 an hour and gross well into six figures with a full client roster.
Locum tenens physicians earn some of the highest contractor rates in any field. Hourly rates average around $215 across all specialties, with anesthesiology and oncology ranging from $300 to $500 per hour. A full day in those specialties can produce $2,400 to $4,000. Traveling nurses on contract assignments during peak demand often bring in $3,000 to $6,000 per week.
General contractors in residential construction typically charge 15% to 20% of total project budget as their management fee. On a $500,000 custom home, that is a gross fee of $75,000 to $100,000, out of which the contractor pays administrative costs and their own income. Independent electricians and plumbers charge between $65 and $175 per hour. Solo tradespeople in cabinetry or flooring commonly earn $45,000 to $85,000 a year through referral work.
Private military and security contractors overseas have historically commanded daily rates of roughly $500 to $1,500, with hazard pay, lodging, and per-diem stipends added on top. A six-month rotation in a high-threat region can produce gross earnings of $90,000 to $160,000 before taxes.
Management consultants charge on a project basis rather than hourly. A full organizational audit or market-entry strategy can run from $10,000 to $100,000 depending on scope and the consultant’s track record.
Deductions That Rebuild Your Take-Home
The self-employment tax rate looks brutal in isolation, but contractors get access to deductions that W-2 employees do not. Used together, they can meaningfully narrow the gap between gross and net.
Half of Self-Employment Tax
You can deduct the employer-equivalent half of your self-employment tax from gross income on Schedule 1, which lowers the figure used to calculate income tax. No itemizing required.5Office of the Law Revision Counsel. 26 USC 164 – Taxes On $100,000 of net earnings, that deduction is about $7,065.
Health Insurance Premiums
Self-employed individuals can generally deduct 100% of health, dental, and vision premiums for themselves, their spouse, and their dependents as an above-the-line deduction, claimed on Schedule 1 with Form 7206. The deduction is not available for any month you were eligible to participate in an employer-subsidized plan, including a spouse’s employer plan.6Internal Revenue Service. Instructions for Form 7206
Home Office
If you use a space in your home regularly and exclusively for business, the simplified method deducts $5 per square foot up to 300 square feet, for a maximum of $1,500 a year.7Internal Revenue Service. Simplified Option for Home Office Deduction The regular method deducts the business-use percentage of actual home expenses (mortgage interest, utilities, insurance, repairs) and can produce a larger deduction when costs are high.
Qualified Business Income
The Section 199A deduction allows eligible self-employed individuals to deduct up to 20% of qualified business income from taxable income. Originally set to expire at the end of 2025, it was made permanent by the One, Big, Beautiful Bill signed into law in 2025. The full 20% applies below certain income thresholds, with a phase-out range above.8Internal Revenue Service. Qualified Business Income Deduction For a contractor netting $100,000, that is up to $20,000 shaved off taxable income.
Business Operating Expenses
Ordinary and necessary business expenses reduce net self-employment income before self-employment tax is even calculated, so each dollar deducted saves on both income tax and the 15.3% self-employment rate. Common categories include professional liability (errors and omissions) insurance, which typically runs $1,000 to $7,000 a year depending on field and coverage; equipment, software, and tools; vehicle costs (actual expenses or the IRS standard mileage rate); and continuing education that maintains or improves skills in your current field.
Retirement Contributions as a Second Lever
Self-employed retirement accounts allow much larger contributions than a standard IRA, and each dollar contributed reduces taxable income in the year it goes in.
A Simplified Employee Pension (SEP) IRA accepts up to 25% of net self-employment earnings, capped at $69,000 for 2026, with no annual IRS filing and contributions allowed up through your tax-filing deadline including extensions.9Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs)
A Solo 401(k) is available to self-employed workers with no employees other than a spouse. You can defer up to $24,500 in 2026 as the “employee” and add an employer contribution on top, up to a combined limit of $72,000.10Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits Workers aged 50 and up qualify for catch-up contributions, and those aged 60 to 63 can push the total as high as $83,250 in 2026 under enhanced catch-up rules. A Roth option is also available.
For a contractor netting $150,000, maxing a Solo 401(k) at $72,000 cuts taxable income nearly in half.
Quarterly Estimated Payments
Because no employer withholds taxes from your pay, you send the IRS estimated payments four times a year. Miss them and you owe an underpayment penalty, which accrued at a 7% annual rate (compounded daily) in the first quarter of 2026.11Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026
The 2026 deadlines are April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. You can skip the January payment if you file your full 2026 return and pay any remaining balance by February 1, 2027.12IRS.gov. Form 1040-ES (2026) Each payment should cover roughly one quarter of total expected tax liability, including both income tax and self-employment tax. Form 1040-ES or tax-preparation software can help you set the number at the start of the year.
If You Work Overseas
Contractors who live and work outside the United States for extended periods may qualify for the foreign earned income exclusion, which shields a portion of earnings from federal income tax. The 2026 maximum is $132,900 per person.13Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 To qualify, your tax home has to be in a foreign country and you must meet either the bona fide residence test (resident of a foreign country for an entire tax year) or the physical presence test (330 full days in a foreign country during a 12-month period).14Internal Revenue Service. Figuring the Foreign Earned Income Exclusion One important boundary: the exclusion cuts federal income tax, but self-employment tax still applies to the full amount of your net earnings.
Pricing to Protect Your Take-Home
Because the gap between billings and net is so wide, experienced contractors set aside 25% to 30% of every payment for taxes and price services high enough that the remaining 70% covers both operating expenses and a livable income. Treating gross billings as spendable income is the surest way to get surprised at tax time. The faster you build taxes and overhead into your rate, the closer your take-home gets to the top of that 60% to 67% range.
