Pilot Income in South Carolina: Post-Tax Estimator

How US Federal Income Tax Is Calculated on Your Salary

The US federal income tax system is progressive and marginal: tax rates apply only to the portion of your income within each bracket—not to your full salary. This is the most important concept to understand before reading any salary tax estimate.

Step 1: Determine Gross Income Include all W-2 wages, salary, tips, and any other compensation. Overtime and bonuses count as ordinary income.

Step 2: Subtract Pre-Tax Deductions 401(k) traditional contributions, HSA contributions, and employer-sponsored health/dental/vision premiums reduce your gross income *before* federal income tax is computed (though FICA still applies to gross).

Step 3: Apply the Standard Deduction (2026)

• Single filers: $15,000
• Married Filing Jointly: $30,000
• Head of Household: $22,500

This is the amount of income completely exempt from federal tax. Only the remainder is your taxable income.

Step 4: Apply the 2026 Federal Tax Brackets

| Bracket | Single Filer | Married Filing Jointly | Head of Household | |---|---|---|---| | 10% | $0 – $11,925 | $0 – $23,850 | $0 – $17,000 | | 12% | $11,926 – $48,475 | $23,851 – $96,950 | $17,001 – $64,850 | | 22% | $48,476 – $103,350 | $96,951 – $206,700 | $64,851 – $103,350 | | 24% | $103,351 – $197,300 | $206,701 – $394,600 | $103,351 – $197,300 | | 32% | $197,301 – $250,525 | $394,601 – $501,050 | $197,301 – $250,500 | | 35% | $250,526 – $626,350 | $501,051 – $751,600 | $250,501 – $626,350 | | 37% | Over $626,350 | Over $751,600 | Over $626,350 |

Worked example – $80,000 salary, single filer:

• Standard deduction: $15,000 → Taxable income: $65,000
• 10% on $11,925 = $1,193
• 12% on $36,550 ($48,475 − $11,925) = $4,386
• 22% on $16,525 ($65,000 − $48,475) = $3,636
• Total federal income tax: $9,215 (effective rate: 11.5%)

📋 FICA: Social Security and Medicare Taxes

FICA taxes are separate from income tax and fund Social Security retirement/disability and Medicare:

| Component | Employee Rate | Employer Rate | Wage Cap | |---|---|---|---| | Social Security | 6.2% | 6.2% | $176,100 (2026) | | Medicare | 1.45% | 1.45% | No cap | | Additional Medicare | 0.9% | None | Earnings above $200,000 (single) |

FICA applies to gross wages before any deductions. Once you've earned $176,100 in 2026, Social Security withholding stops for the rest of the year—you'll see a noticeable bump in take-home pay at that point.

💡 How Pre-Tax Deductions Reduce Your Tax Bill

Every dollar you contribute to a traditional 401(k), HSA, or employer health plan reduces your federal and (usually) state taxable income:

| Pre-Tax Deduction | 2026 Limit | Tax Savings at 22% Bracket | |---|---|---| | 401(k) Traditional | $23,500 ($31,000 if 50+) | Up to $5,170 federal | | HSA (self-only) | $4,300 | $946 federal | | HSA (family) | $8,550 | $1,881 federal | | Health Insurance Premium | Employer-determined | Varies |

Key insight: A single filer contributing $23,500 to a 401(k) on an $80,000 salary reduces their taxable income from $65,000 to $41,500—pushing them from the 22% bracket into the 12% bracket on most of their income.

🔄 W-4: Controlling Your Withholding

The Form W-4 you submit to your employer controls how much federal income tax is withheld per paycheck. Key elections:

• Step 3 (Dependents): Reduces withholding by the Child Tax Credit amount ($2,000 per child)
• Step 4(b) (Deductions): If you plan to itemize, enter estimated deductions above the standard deduction to reduce withholding
• Step 4(c) (Extra withholding): Add a flat amount if you have multiple jobs or other income not subject to withholding

Refund vs balance due: A large refund (>$1,000) means you over-withheld—you gave the IRS an interest-free loan. Ideally, aim for $0–$500 refund or owe. The IRS withholding estimator at irs.gov/W4app can help you calibrate precisely.
