• State and local taxes vary and may require separate calculations
• Consider tax-advantaged strategies to minimize your liability

Common Deductions and Credits

Many taxpayers can reduce taxes through:

• Standard deduction or itemized deductions
• Retirement account contributions
• Education credits
• Child tax credit
• Mortgage interest deduction

The 1099 Difference

A 1099 contractor and a W-2 employee doing identical work take home very different amounts from the same headline number.

	W-2 at $85,000	1099 at $85,000
FICA	7.65% ($6,503)	15.3% ($12,010)
Health insurance	Employer-subsidised	Yours entirely
Paid leave	15–25 days	None
Unemployment insurance	Covered	Not eligible
Retirement match	Often 3–6%	None

A 1099 rate needs to be roughly 25–35% above the W-2 equivalent to reach the same position.

Against that, contractors deduct genuine business expenses — home office, equipment, mileage, software, health insurance premiums — and can use a Solo 401(k) with a much higher combined contribution limit than an employee plan.

Note that worker classification is not a choice. The IRS applies behavioural, financial and relationship tests; misclassification carries back taxes and penalties for the payer.

A Note on These Figures

Brackets, thresholds and the standard deduction shown here are for tax year 2024, filed in 2025, and they are indexed to inflation every year. State tax is not included and ranges from nothing at all (Florida, Texas, Washington and six others) to 13.3% in California.

This is an estimate, not tax advice. Anything involving equity compensation, multiple states, self-employment or a life change is worth an hour of a professional's time.

Worked Through the Brackets

On $85,000 of gross income, filing single, taking the $14,600 standard deduction — so $70,400 of taxable income:

Bracket	Range	Income taxed here	Tax
10%	$0 – $11,600	$11,600	$1,160
12%	$11,600 – $47,150	$35,550	$4,266
22%	$47,150 – $100,525	$23,250	$5,115
Total			$10,541

That is a 12.4% effective rate against a 22% marginal rate. The two answer different questions: the marginal rate is what the next dollar costs, and it is the one that decides whether a 401(k) contribution or an extra shift is worth it. The effective rate is what you actually paid, and it is the one to budget against.

The Same Income, Different Sources

Source	Federal tax on it
Wages (above)	$10,541
Self-employment profit	$10,541 income tax plus $12,010 SE tax
Long-term capital gain of $10,000	$1,500 at 15%

Where income comes from changes the bill more than how much of it there is. A self-employed filer at this level pays roughly $12,010 that an employee never sees, because there is no employer paying the other half of FICA.
