Understand the gap between what you earn and what you keep. Learn to calculate your net income after taxes, deductions, and withholdings.
There's often a significant gap between your salary and what actually lands in your bank account. That $85,000 job offer? You'll likely take home somewhere around $58,000-$65,000 after taxes and deductions. Understanding exactly how that number is calculated empowers you to negotiate better, budget accurately, and make informed financial decisions.
This guide breaks down the complete process of calculating net income from gross pay, covering federal taxes, state taxes, payroll deductions, and voluntary withholdings.
Gross income is your total compensation before any deductions. For salaried employees, it's your annual salary. For hourly workers, it's hours worked times hourly rate, plus overtime. It also includes bonuses, commissions, tips, and other taxable compensation.
Net income (also called take-home pay) is what remains after all mandatory and voluntary deductions are subtracted from your gross income. It's the money you actually receive in your paycheck and can use for living expenses, savings, and discretionary spending.
Key takeaway: Gross income is what you earn. Net income is what you keep. The difference can be 25-40% of your gross pay.
Paycheck deductions fall into three categories: mandatory taxes, payroll taxes, and voluntary deductions. Here's what each includes:
The federal government taxes your income progressively — higher income portions are taxed at higher rates. For 2024, the seven federal tax brackets for single filers are:
| Tax Rate | Taxable Income Range (Single) | Tax Owed |
|---|---|---|
| 10% | $0 – $11,600 | 10% of taxable income |
| 12% | $11,601 – $47,150 | $1,160 + 12% over $11,600 |
| 22% | $47,151 – $100,525 | $5,426 + 22% over $47,150 |
| 24% | $100,526 – $191,950 | $17,168.50 + 24% over $100,525 |
| 32% | $191,951 – $243,725 | $39,110.50 + 32% over $191,950 |
| 35% | $243,726 – $609,350 | $55,678.50 + 35% over $243,725 |
| 37% | Over $609,350 | $183,647.25 + 37% over $609,350 |
Important: these rates apply to your taxable income, not your gross income. Taxable income is reduced by the standard deduction ($14,600 for single filers in 2024) or itemized deductions.
Most states impose their own income tax on top of federal taxes. Rates vary dramatically:
Some cities also impose local income taxes, such as New York City (up to 3.876%) and various municipalities in Ohio, Pennsylvania, and Kentucky.
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare:
Your employer matches both Social Security and Medicare contributions, effectively doubling the amount going into these programs.
These are withholdings you choose to have taken from your paycheck:
For salaried employees, this is straightforward — your annual salary. For hourly workers, multiply your hourly rate by hours worked per year (typically 2,080 for full-time). Include all taxable compensation: bonuses, commissions, overtime pay, and tips.
Reduce your gross income by pre-tax contributions like 401(k), HSA, FSA, and some health insurance premiums. These lower your taxable income, reducing your tax burden.
Subtract the standard deduction ($14,600 single / $29,200 married filing jointly for 2024) or your itemized deductions from your adjusted gross income. This gives you your taxable income.
Use the progressive tax brackets to calculate your federal income tax. Remember: each dollar is only taxed at the rate of the bracket it falls into, not your highest bracket rate.
Apply your state's income tax rate to your taxable income (some states use gross income). Add any local or city taxes that apply.
Calculate 6.2% for Social Security (up to the wage base) plus 1.45% for Medicare. Add the additional 0.9% Medicare tax if applicable.
Remove any after-tax deductions like Roth 401(k) contributions, charitable donations through payroll, union dues, or garnishments.
Let's walk through a complete calculation for someone earning $85,000 per year in California:
| Category | Calculation | Amount |
|---|---|---|
| Gross Annual Salary | — | $85,000 |
| 401(k) Contribution (5%) | $85,000 × 5% | -$4,250 |
| Adjusted Gross Income | $85,000 - $4,250 | $80,750 |
| Standard Deduction | — | -$14,600 |
| Taxable Income | $80,750 - $14,600 | $66,150 |
| Federal Income Tax | Progressive brackets | -$9,733 |
| California State Tax | Progressive brackets | -$4,259 |
| Social Security (6.2%) | $85,000 × 6.2% | -$5,270 |
| Medicare (1.45%) | $85,000 × 1.45% | -$1,233 |
| Health Insurance | Employer plan | -$2,400 |
| Annual Net Income | Total deductions | $57,855 |
| Monthly Take-Home Pay | $57,855 ÷ 12 | $4,821 |
From $85,000 gross to $57,855 net — that's a 32% reduction. The effective tax rate is about 11.4% federal and 5% state, with FICA and insurance making up the rest.
Contributing to a 401(k) or HSA reduces your taxable income dollar-for-dollar. For example, increasing your 401(k) contribution from 5% to 10% on an $85,000 salary saves you over $1,000 in federal taxes while building your retirement savings.
If you consistently get large tax refunds, you're over-withholding — essentially giving the government an interest-free loan. Adjust your W-4 to increase your take-home pay and put the difference to work in savings or investments.
Tax credits directly reduce your tax bill, dollar for dollar. Common credits include the Child Tax Credit ($2,000 per child), Earned Income Tax Credit (up to $7,430), Child and Dependent Care Credit, and education credits like the American Opportunity Credit.
If you have geographic flexibility, living in a state with no income tax (Texas, Florida, Nevada, Washington) can save thousands annually. On an $85,000 salary, moving from California to Texas saves over $4,000 per year in state taxes alone.
Self-employed individuals face a different calculation. You're responsible for the full 15.3% FICA tax (both employer and employee portions), plus quarterly estimated tax payments. However, you can deduct half of the self-employment tax and business expenses before calculating income tax.
Key differences for self-employed workers:
Understanding your net income is foundational to sound financial planning:
Gross income is your total earnings before any deductions — your salary, bonuses, commissions, and other compensation. Net income (take-home pay) is what remains after federal taxes, state taxes, Social Security, Medicare, health insurance premiums, retirement contributions, and other deductions are subtracted. Net income is typically 60-75% of gross income.
The average American worker pays about 25-35% of their gross income in combined federal, state, and payroll taxes. This includes federal income tax (10-37% depending on bracket), state income tax (0-13% depending on state), Social Security (6.2% up to the wage base), and Medicare (1.45%). The exact amount depends on your income level, filing status, deductions, and state of residence.
Your paycheck reflects net income, not gross. The difference comes from mandatory deductions (federal/state taxes, Social Security, Medicare) and voluntary deductions (health insurance, 401k contributions, HSA, life insurance). Together, these can reduce your paycheck by 25-40% of your gross salary.
Net income excludes taxes. It is your income after all taxes and deductions have been removed. For employees, it's your take-home pay. For businesses, net income is revenue minus all expenses including taxes.
The US uses a progressive tax system with marginal tax brackets. Each bracket applies only to income within that range. For example, if you're single and earn $100,000, you don't pay 24% on all of it. You pay 10% on the first $11,600, 12% on income up to $47,150, and 22% on income up to $100,525. Only the income in the highest bracket is taxed at that rate.
