Frequently Asked Questions
Net pay is calculated by subtracting all deductions from your gross pay:
- Start with gross pay (your total earnings before any deductions)
- Subtract pre-tax deductions (401(k), health insurance premiums, HSA contributions, etc.)
- Calculate and subtract taxes on the remaining taxable income:
- Federal income tax (based on your W-4 and tax brackets)
- State income tax (varies by state)
- Social Security tax (6.2% up to annual wage base)
- Medicare tax (1.45% on all earnings, plus 0.9% additional for high earners)
- Subtract post-tax deductions (Roth 401(k), disability insurance, garnishments, etc.)
The result is your net pay, also called "take-home pay" — the amount that actually gets deposited into your bank account.
Yes. You can adjust your federal tax withholding by submitting a new Form W-4 to your employer. The IRS redesigned the W-4 form in 2020, removing allowances and making it easier to match your withholding to your tax liability.
Consider adjusting your withholding when:
- You consistently receive large tax refunds (meaning you're overwithholding)
- You frequently owe taxes when filing your return (underwithholding)
- Your life circumstances change (marriage, divorce, new child, buying a home, second job, etc.)
Use the IRS Tax Withholding Estimator tool to determine the right withholding for your situation.
Pre-tax deductions are taken from your gross pay before taxes are calculated, reducing your taxable income and thus reducing the amount of tax you pay. Common pre-tax deductions include:
- Traditional 401(k), 403(b), or 457 plan contributions
- Health, dental, and vision insurance premiums
- Health Savings Account (HSA) contributions
- Flexible Spending Account (FSA) contributions
- Commuter benefits
- Dependent care FSA contributions
Post-tax deductions are taken after taxes have been calculated and withheld. These include:
- Roth 401(k) or Roth IRA contributions
- Disability insurance premiums
- Life insurance premiums (usually)
- Union dues
- Wage garnishments
- Charitable contributions (usually)
Pre-tax deductions generally provide immediate tax savings, while post-tax deductions like Roth contributions may provide tax advantages later.
Social Security tax (also known as OASDI - Old Age, Survivors, and Disability Insurance) is calculated at a flat rate of 6.2% on wages up to the annual wage base limit. For 2025, the wage base limit is $168,600 (up from $160,200 in 2024).
This means:
- You pay 6.2% on all earnings up to $168,600
- Any earnings above $168,600 are not subject to Social Security tax
- The maximum Social Security tax per employee in 2025 is $10,453.20 ($168,600 × 6.2%)
Your employer also pays a matching 6.2% contribution. If you're self-employed, you pay both portions through self-employment tax (12.4% total).
Unlike Social Security, Medicare tax (1.45%) has no wage base limit and applies to all earnings. Plus, individuals earning over $200,000 ($250,000 for married filing jointly) pay an additional 0.9% Medicare surtax on earnings above that threshold.
Bonuses are typically subject to different withholding rules than regular wages:
- Percentage method: Most employers withhold a flat 22% federal tax rate for supplemental wages (bonuses, commissions) up to $1 million
- Aggregate method: Some employers add the bonus to your regular paycheck and withhold based on the combined amount, which might result in more withholding
Overtime pay (typically 1.5x your regular hourly rate) is taxed as regular wages but can temporarily push you into a higher tax bracket for that pay period, leading to higher withholding. However, your actual tax liability is based on your total annual income, so you may get some of this back when you file your tax return.
Both bonuses and overtime are also subject to Social Security and Medicare taxes, plus applicable state and local taxes.
As of 2025, nine states do not collect state income tax on wages:
- Alaska
- Florida
- Nevada
- New Hampshire (taxes investment income only)*
- South Dakota
- Tennessee
- Texas
- Washington
- Wyoming
*New Hampshire doesn't tax wages but does tax investment income (interest and dividends).
Keep in mind that states without income tax generally make up for this revenue through other taxes, such as higher property taxes, sales taxes, or other fees. Additionally, if you work in a state with income tax but live in a state without income tax (or vice versa), you may still be subject to income tax in the state where you work.
The main differences between W-2 employees and 1099 contractors relate to tax withholding, benefits, and work arrangements:
| W-2 Employee | 1099 Contractor |
|---|---|
| Employer withholds income taxes | Responsible for paying own income taxes quarterly |
| Employer pays 50% of FICA taxes (7.65%) | Pays full self-employment tax (15.3%) |
| May receive employer-sponsored benefits | No employer benefits |
| Employer controls work schedule and methods | Greater autonomy over work schedule and methods |
| Limited business expense deductions | Can deduct business expenses on Schedule C |
If you're a 1099 contractor, you'll need to set aside money for taxes, consider making quarterly estimated tax payments, and track business expenses carefully.
Here are strategic ways to legally increase your take-home pay:
- Review your W-4 withholding: Ensure you're not overwithholding. Use the IRS Withholding Calculator to optimize.
- Maximize pre-tax benefits:
- Contribute to 401(k)/403(b) plans (reduces taxable income)
- Use Health Savings Accounts (HSAs) if eligible
- Utilize Flexible Spending Accounts (FSAs) for healthcare or dependent care
- Take advantage of commuter benefit programs for transportation costs
- Choose the right health insurance plan: Balance premium costs against expected healthcare needs
- Consider tax credits: Research eligibility for credits like the Child Tax Credit or Education credits
- Manage your income timing: If possible, defer income to lower-income years or accelerate deductions in high-income years
Remember that tax-reduction strategies should be part of a broader financial plan that balances current needs with future goals like retirement savings.

Understanding Your Paycheck: The Complete Guide
Anatomy of a Paycheck Stub
A typical paycheck stub contains important financial information about your earnings and deductions:
| Section | What It Shows |
|---|---|
| Gross Earnings | Total pay before any deductions |
| Pre-tax Deductions | Health insurance, retirement plans, FSA/HSA contributions |
| Taxable Wages | Amount subject to taxes (gross pay minus pre-tax deductions) |
| Tax Withholdings | Federal, state, local taxes, Social Security, Medicare |
| Post-tax Deductions | Roth contributions, garnishments, disability insurance |
| Net Pay | Final take-home amount |
| YTD Totals | Year-to-date accumulation of all categories |
Pay Period Comparisons
Different pay periods affect how your annual salary is distributed:
| Pay Frequency | Periods/Year | Calculation |
|---|---|---|
| Weekly | 52 | Annual salary ÷ 52 |
| Bi-weekly | 26 | Annual salary ÷ 26 |
| Semi-monthly | 24 | Annual salary ÷ 24 |
| Monthly | 12 | Annual salary ÷ 12 |
Did you know?
If you're paid bi-weekly, you'll receive 26 paychecks per year, which means twice a year you'll receive three paychecks in a month instead of two. These "extra" paychecks can be excellent opportunities for additional savings or debt reduction.
Progressive Taxation Explained
The U.S. employs a progressive tax system, meaning different portions of your income are taxed at different rates. Many people misunderstand this, thinking a raise could push them into a higher bracket and result in less take-home pay overall—this is not true.
For example, if you're single with a $60,000 taxable income in 2024:
- First $11,600 is taxed at 10% = $1,160
- Income from $11,601 to $47,150 is taxed at 12% = $4,266
- Income from $47,151 to $60,000 is taxed at 22% = $2,827
- Total federal income tax = $8,253 (effective rate of ~13.8%)
If you received a $10,000 raise, only that additional amount would be taxed at 22%, not your entire income.
2024 Federal Tax Brackets (Single Filer)
| Income Range | Tax Rate |
|---|---|
| $0 - $11,600 | 10% |
| $11,601 - $47,150 | 12% |
| $47,151 - $100,525 | 22% |
| $100,526 - $191,675 | 24% |
| $191,676 - $243,725 | 32% |
| $243,726 - $609,350 | 35% |
| Over $609,350 | 37% |
Understanding FICA Tax Changes Throughout the Year
For high-income earners, your paycheck size changes throughout the year due to the Social Security wage base limit. In 2024, once you've earned $160,200, Social Security tax (6.2%) stops being withheld from your paycheck.
Example: $200,000 Annual Salary
Monthly salary: $16,667
Social Security tax (early months): $1,033 per month
After reaching wage base (around October): Social Security tax drops to $0, resulting in approximately $1,033 more take-home pay per month for the remainder of the year.
Social Security Wage Base History
| Year | Wage Base Limit | Maximum Tax |
|---|---|---|
| 2025 | $168,600 (projected) | $10,453 |
| 2024 | $160,200 | $9,932 |
| 2023 | $160,200 | $9,932 |
| 2022 | $147,000 | $9,114 |
| 2021 | $142,800 | $8,854 |

- Dependents: Children and other dependents that qualify for tax credits
- Other Income: Non-job income like interest, dividends, or retirement
- Deductions: Itemized deductions that exceed the standard deduction
- Extra Withholding: Additional amount to withhold from each paycheck
Complete a new W-4 whenever your personal or financial situation changes or if your tax return shows you need to adjust your withholding.
W-4 Best Practices
- Use the IRS Tax Withholding Estimator tool for accuracy
- Complete a "paycheck checkup" after major life changes
- Review annually in January to account for tax law changes
- Consider additional withholding if you have multiple income sources
- Consult a tax professional if your situation is complex
