Pre-tax deductions explained
Pre-tax deductions lower your taxable income, reducing both federal and state income tax (and often FICA):
- 401(k) / 403(b): Traditional contributions reduce taxable income now; taxed in retirement. 2024 limit: $23,000 ($30,500 if 50+).
- HSA (Health Savings Account): Triple tax advantage—pre-tax contributions, tax-free growth, tax-free withdrawals for medical expenses. 2024 limit: $4,150 individual, $8,300 family.
- Health insurance premiums: Employer-sponsored plan contributions are typically pre-tax.
- FSA (Flexible Spending Account): Pre-tax dollars for healthcare expenses. 2024 limit: $3,200 per employer.
- Dental/Vision insurance: Premiums usually deducted pre-tax.
FICA taxes: Social Security and Medicare
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare:
- Social Security: 6.2% employee + 6.2% employer on wages up to $168,600 (2024). Self-employed pay 12.4%.
- Medicare: 1.45% employee + 1.45% employer on all wages (no cap).
- Additional Medicare Tax: 0.9% on wages over $200,000 (single) or $250,000 (married filing jointly). Only the employee portion applies.
State income tax rates
State taxes vary significantly:
- No income tax: Alaska, Florida, Nevada, New Hampshire (taxes dividends/interest only), South Dakota, Tennessee, Texas, Washington, Wyoming
- Flat tax states: Colorado (4.4%), Illinois (4.95%), Indiana (3.23%), Michigan (4.25%), North Carolina (4.75%), Pennsylvania (3.07%)
- Progressive tax states: Most states use brackets like federal tax, ranging from ~1% to 13.3% (California top bracket)
This calculator uses simplified average or flat rates for each state. Actual state tax depends on your specific situation, local taxes, and state-specific deductions.
What reduces take-home pay?
Beyond taxes and pre-tax deductions, these items may appear on your pay stub:
- Roth 401(k): After-tax retirement contributions (doesn't reduce taxable income)
- Garnishments: Court-ordered payments for child support, student loans, or debts
- Union dues: Regular membership fees
- Life/disability insurance: Optional coverage premiums
- Commuter benefits: Pre-tax transit/parking (up to $300/month in 2024)
How to increase take-home pay
- Adjust W-4 withholdings: If you consistently get large refunds, you may be over-withheld
- Maximize pre-tax benefits: HSA, FSA, commuter benefits, dependent care FSA
- Review health plan options: Lower premium plans increase take-home but may cost more overall
- Consider Roth vs. traditional: Roth 401(k) doesn't reduce current taxes but provides tax-free retirement income
- Check for errors: Verify your filing status and allowances on your W-4
