How is payroll calculated?

Payroll calculation follows these steps: (1) Calculate Gross Pay = Base Salary + Allowances + Bonuses + Overtime, (2) Subtract Pre-tax Deductions (401k, health insurance, HSA), (3) Calculate FICA: Social Security 6.2% + Medicare 1.45%, (4) Calculate Federal Income Tax using IRS brackets, (5) Apply State/Local Taxes, (6) Subtract Post-tax Deductions. Net Pay = Gross Pay - All Deductions - Taxes.

What percentage is taken out of a paycheck?

Total payroll deductions typically range 20-30% of gross pay: Federal Income Tax (10-37% based on bracket), FICA Taxes (7.65% - Social Security 6.2% + Medicare 1.45%), State Income Tax (0-13.3% varies by state), Pre-tax Benefits (0-10%), Post-tax Deductions (varies). For a $60,000 annual salary, expect approximately 23-28% total deductions, leaving 72-77% as net pay.

FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare programs. For 2025: Social Security is 6.2% on wages up to $176,100, Medicare is 1.45% on all wages (no cap), Additional Medicare of 0.9% applies to wages over $200,000. Employers match Social Security and Medicare (but not additional Medicare). Total FICA for most employees is 7.65% of gross pay.

What is the difference between gross pay and net pay?

Gross Pay is total earnings before any deductions (base salary + bonuses + overtime + allowances). Net Pay (take-home pay) is what remains after all deductions and taxes. Formula: Net Pay = Gross Pay - Pre-tax Deductions - FICA Taxes - Federal Tax - State Tax - Post-tax Deductions. Example: $5,000 gross monthly becomes ~$3,800 net after deductions (76% take-home).

Are 401(k) contributions taken before or after taxes?

Traditional 401(k) contributions are PRE-TAX, reducing taxable income and lowering current tax liability. Roth 401(k) contributions are POST-TAX, paid with after-tax dollars but grow tax-free. Example: $5,000 gross with $250 traditional 401(k) = $4,750 taxable income. With Roth 401(k), full $5,000 is taxable but distributions are tax-free in retirement. 2025 contribution limit: $23,500 (under 50).

How do I calculate overtime pay?

Overtime is calculated at 1.5× regular hourly rate for hours over 40 per week (US federal law). Formula: Overtime Rate = (Annual Salary / 2,080 hours) × 1.5. Example: $60,000 annual = $28.85/hour regular rate. Overtime rate = $28.85 × 1.5 = $43.27/hour. For 5 overtime hours: $43.27 × 5 = $216.35 additional pay. Some states have daily overtime rules.

What states have no income tax?

Nine US states have no state income tax (as of 2025): Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (only taxes dividends/interest). This means higher take-home pay as employees only pay federal taxes, FICA, and local taxes (if applicable). However, these states may have higher sales, property, or other taxes.

How much Social Security tax will I pay?

Social Security tax is 6.2% on wages up to $176,100 for 2025. Maximum annual Social Security tax: $176,100 × 6.2% = $10,918.20. Your employer matches this amount. If you earn $60,000, you pay $3,720 annually ($310/month). If you earn over $176,100, you pay the maximum. Self-employed pay both portions (12.4%) up to the wage base.

Can my employer deduct money from my paycheck?

Legal deductions include: (1) Mandatory taxes (federal, state, FICA), (2) Court-ordered garnishments (child support, tax liens, student loans), (3) Voluntary deductions with written consent (benefits, 401k, union dues). Employers CANNOT deduct for: cash register shortages (in most states), uniforms/tools, damages/breakage, if it brings pay below minimum wage. All deductions must comply with federal and state labor laws.

How do I change my tax withholding?

Submit a new Form W-4 to your employer's HR/payroll department. Reasons to adjust: marriage/divorce, birth of child, second job, large refund/tax bill. Increase withholding: reduce allowances or request additional amount. Decrease withholding: increase allowances if eligible. Use IRS Tax Withholding Estimator to determine correct amount. Changes typically take effect within 1-2 pay periods. Review withholding annually or after major life changes.

1. Gross Pay Calculation

Gross Pay = Base Salary + Overtime + Bonuses + Allowances

Example: $5,000 base + $200 overtime + $500 bonus = $5,700 gross pay

2. Taxable Income

Taxable Income = Gross Pay - Pre-tax Deductions

Example: $5,000 gross - $250 (401k) - $200 (health insurance) = $4,550 taxable income

3. FICA Taxes (Social Security & Medicare)

Social Security = Taxable Income × 6.2%

Medicare = Taxable Income × 1.45%

Example: $4,550 taxable × 6.2% = $282.10 Social Security, $4,550 × 1.45% = $65.98 Medicare

4. Federal Income Tax

Federal Tax = Taxable Income × Tax Rate %

Example: $4,550 monthly with a 12% rate = $546 federal tax

5. Net Pay (Take-Home)

Net Pay = Gross Pay - All Deductions - All Taxes

Example: $5,000 - $450 (deductions) - $894 (taxes) = $3,656 net pay (73.1% take-home)
