Your salary offer says $85,000 per year. But when your first paycheck arrives, the number looks very different. That gap between what you earn and what you actually keep is one of the most important financial concepts to understand — and it goes far beyond income tax alone.
This guide walks you through every deduction that transforms your gross income into net income, shows you how to calculate each one, and reveals strategies to maximize what ends up in your pocket.
Skip the manual math. Our free calculator handles federal tax, state tax, FICA, and all major deductions.
Try the Net Income Calculator →Gross income is the total amount you earn before any deductions. For W-2 employees, this includes your base salary or hourly wages, overtime pay, bonuses, commissions, tips, and any other compensation from your employer.
For freelancers and self-employed individuals, gross income is your total revenue minus business expenses — this is called net self-employment income, and it becomes the starting point for your personal tax calculations.
Your W-2 Box 1 (Wages, tips, other compensation) may differ from your total gross pay. It excludes certain pre-tax deductions like 401(k) contributions, HSA contributions, and some insurance premiums. Box 1 is the number that actually matters for income tax purposes.
Before income tax is calculated, certain deductions reduce your taxable income. These are called "above-the-line" or pre-tax deductions, and they lower both your federal and state tax liability.
In 2026, you can contribute up to $23,500 to a traditional 401(k) ($31,000 if you're 50 or older). Every dollar you contribute reduces your taxable income dollar-for-dollar. Someone earning $85,000 who contributes $10,000 to their 401(k) is taxed as if they earned $75,000.
If you have a high-deductible health plan, you can contribute up to $4,300 (individual) or $8,550 (family) to an HSA. This is the only account that is triple tax-advantaged: tax-deductible going in, tax-free growth, and tax-free withdrawals for qualified medical expenses.
Employer-sponsored health insurance premiums are typically deducted pre-tax, meaning they reduce both your income tax and FICA tax liability. This is a significant benefit — if your employer plan costs $600/month, you save roughly $180–$250 per month in taxes compared to buying insurance with after-tax dollars.
FSAs allow up to $3,300 in pre-tax contributions for healthcare expenses. Dependent care FSAs allow up to $5,000 for childcare. Unlike HSAs, FSA funds generally don't roll over (though some plans allow a $640 carryover in 2026).
The United States uses a progressive tax system. This means your income is divided into portions, and each portion is taxed at a different rate. A common misconception is that earning more money pushes your entire salary into a higher bracket — in reality, only the income within each bracket is taxed at that rate.
| Tax Rate | Taxable Income Range | Tax Owed |
|---|---|---|
| 10% | $0 – $11,925 | 10% of taxable income |
| 12% | $11,926 – $48,475 | $1,192.50 + 12% over $11,925 |
| 22% | $48,476 – $103,350 | $5,578.50 + 22% over $48,475 |
| 24% | $103,351 – $197,300 | $17,651 + 24% over $103,350 |
| 32% | $197,301 – $250,525 | $40,199 + 32% over $197,300 |
| 35% | $250,526 – $626,350 | $57,231 + 35% over $250,525 |
| 37% | Over $626,350 | $188,769 + 37% over $626,350 |
A single filer with $75,000 in taxable income: $1,192.50 (10% bracket) + $4,386 (12% bracket) + $5,835.50 (22% bracket) = $11,414 in federal income tax. Their effective federal tax rate is 15.2% — well below their 22% marginal rate.
State taxes add another layer of complexity. Rates range from 0% (nine states have no income tax) to 13.3% (California's top rate). Most states use progressive brackets similar to the federal system, while some use a flat rate.
| Category | States | Top Rate |
|---|---|---|
| No Income Tax | AK, FL, NV, NH*, SD, TN, TX, WA, WY | 0% |
| Low Tax (under 5%) | IN, AZ, PA, CO, UT | 2.5–4.4% |
| Moderate Tax (5–8%) | GA, NC, VA, MA, WI | 5.2–7.0% |
| High Tax (8%+) | CA, NY, NJ, HI, OR | 8.0–13.3% |
*New Hampshire taxes dividends and interest at 4%.
Some cities also impose local income taxes — New York City (up to 3.876%), Baltimore, Detroit, and several cities in Ohio, Kentucky, and Pennsylvania. These compound on top of state taxes.
FICA (Federal Insurance Contributions Act) is a mandatory payroll tax split between you and your employer:
You pay both the employer and employee portions — that's 12.4% for Social Security and 2.9% for Medicare, totaling 15.3%. However, you can deduct half of this (the employer-equivalent portion) on your tax return, and the Qualified Business Income deduction may further reduce your liability.
After all taxes are calculated, some deductions come from your remaining pay:
Your net income number tells you what you take home, but it doesn't tell you what that money can actually buy. Purchasing power depends on three critical factors:
A $100,000 salary in San Francisco has dramatically less purchasing power than the same salary in Indianapolis. The median rent in San Francisco is roughly 3.5× higher, groceries cost 30–40% more, and transportation expenses are elevated. Use cost-of-living calculators to compare what your net income means in different locations.
With inflation running at 2.5–3.5% in recent years, your money loses purchasing power over time. A $75,000 net income in 2026 buys roughly what $65,000 bought five years ago. This makes salary growth targets essential — if your raises don't exceed inflation, you're effectively taking a pay cut.
Two people with the same gross income can have vastly different net incomes based on their tax strategy. Maximizing pre-tax retirement contributions, choosing the right filing status, timing deductions, and leveraging tax credits (like the Child Tax Credit or Earned Income Tax Credit) can save thousands of dollars per year.
Let's calculate the net income for Maria, a software engineer in Austin, Texas:
| Component | Amount |
|---|---|
| Gross Annual Salary | $120,000 |
| 401(k) Contribution (10%) | −$12,000 |
| HSA Contribution | −$4,300 |
| Health Insurance Premium | −$7,200 |
| Adjusted Gross Income | $96,500 |
| Standard Deduction | −$15,000 |
| Taxable Income | $81,500 |
| Federal Income Tax | −$13,214 |
| State Income Tax (Texas: 0%) | $0 |
| Social Security (6.2% of $120,000) | −$7,440 |
| Medicare (1.45% of $120,000) | −$1,740 |
| Annual Net Income | $77,106 |
| Monthly Net Income | $6,426 |
| Effective Tax Rate | 35.7% |
Maria's $120,000 salary becomes $77,106 in take-home pay — a 64.3% retention rate. Living in Texas (no state tax) and maximizing pre-tax accounts significantly boost her net income compared to peers in high-tax states.
