Understanding Paycheck Deductions: US Edition

Your pay stub includes taxes, benefits, and voluntary deductions. Knowing what each line means helps you confirm accuracy and optimize take-home pay.

Common deductions:
- Federal and state income tax withholding: based on your W-4 and pay frequency.
- Social Security and Medicare (FICA): fixed percentages of wages.
- Retirement contributions: 401(k) or other plans reduce taxable income if pre-tax.
- Health insurance premiums: may be pre-tax deductions, lowering taxable income.

Voluntary benefits: flexible spending accounts (FSA), health savings accounts (HSA), commuter benefits, and life insurance often appear as deductions and can provide tax advantages.

When reviewing a pay stub, ensure hours, pay rate, and year-to-date totals are sensible. If withholding seems off, use a withholding estimator and update your W-4. For changes in life circumstances—marriage, new dependents, side income—revisit withholding and benefits elections.

Small adjustments can meaningfully affect take-home pay while maintaining appropriate tax compliance and benefit coverage.
