Every paycheck in America has three mandatory federal deductions. Understanding each one helps you verify your stub is correct and plan your budget accurately.
Federal income tax is withheld based on your gross pay, filing status, and the elections on your W-4. The U.S. uses progressive brackets — you pay a lower rate on the first dollars earned and a higher rate only on income above each threshold. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married filing jointly (IRS Revenue Procedure 2025-32). Income below your standard deduction is not taxed at all.
Social Security is withheld at a flat 6.2% on wages up to $184,500 in 2026. Once your cumulative wages for the year hit $184,500, Social Security withholding stops for the remainder of the year. Your employer matches your 6.2% contribution.
Medicare is withheld at a flat 1.45% on all wages with no cap. High earners above $200,000 (single) or $250,000 (married filing jointly) pay an additional 0.9% on wages above that threshold.
These are the official 2026 brackets per IRS Revenue Procedure 2025-32, made permanent by the One Big Beautiful Bill Act signed July 2025.
| Rate | Single Filers | Married Filing Jointly |
|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 |
| 12% | $12,401 – $50,400 | $24,801 – $100,800 |
| 22% | $50,401 – $105,700 | $100,801 – $211,400 |
| 24% | $105,701 – $201,775 | $211,401 – $403,550 |
| 32% | $201,776 – $256,225 | $403,551 – $512,450 |
| 35% | $256,226 – $640,600 | $512,451 – $768,700 |
| 37% | Over $640,600 | Over $768,700 |
Remember: these rates apply only to taxable income — your gross pay minus the standard deduction and any pre-tax contributions.
The table below shows verified 2026 calculations for single filers, monthly basis, before state income tax. All figures calculated using IRS 2026 brackets, $16,100 standard deduction, and FICA rates confirmed from IRS Publication 926.

State income tax is the factor that creates the biggest difference in take-home pay between workers at the same salary level. It ranges from 0% to 13.3%.
| State | Income Tax | Extra on $75k vs No-Tax State |
|---|---|---|
| Alaska, Florida, Nevada, NH, SD, TN, TX, WA, WY | 0% | — |
| Pennsylvania | 3.07% flat | −$2,303/yr |
| Illinois | 4.95% flat | −$3,713/yr |
| New York | 4%–10.9% progressive | −$3,800–$5,200/yr |
| California | 1%–13.3% progressive | −$4,000–$6,000/yr |
The One Big Beautiful Bill Act, signed July 4, 2025, created a new federal deduction for qualifying overtime pay for 2025–2028. Non-exempt W-2 employees can deduct up to $12,500 (single) or $25,000 (married filing jointly) of FLSA-required overtime premium pay from their federal taxable income.
Important: this is a deduction claimed on your annual tax return, not an exemption from withholding. Your employer still withholds federal tax from overtime paychecks. The deduction phases out for single filers earning above $150,000 AGI.
Contributing to pre-tax accounts reduces your taxable income before federal and state taxes are calculated, lowering your withholding on every paycheck.
| Account | 2026 Limit | Tax Benefit on $75k Salary |
|---|---|---|
| 401(k) employee contribution | $24,500 | Up to $5,390/yr in federal tax savings |
| Traditional IRA | $7,500 | Up to $1,650/yr (if deductible) |
| HSA (individual) | $4,400 | Triple tax advantage — deductible, grows tax-free, tax-free withdrawals |
| Health FSA | $3,400 | Saves FICA + income tax on medical spending |

For most Americans earning $40,000 to $120,000, the effective federal income tax rate runs 10 to 22 percent after the standard deduction. Add Social Security at 6.2 percent and Medicare at 1.45 percent and total federal withholding typically runs 18 to 30 percent of gross pay, depending on income and filing status.
A single filer earning $50,000 in 2026 pays approximately $3,820 in federal income tax, $3,100 in Social Security, and $725 in Medicare. Total federal deductions of about $7,645 leave roughly $42,355 net before state taxes. In a no-tax state like Texas, that is your take-home. In New York subtract another $2,103 per year; in California $1,049 (bracket-exact, single filer).
Nine states have zero state income tax in 2026: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Residents keep roughly $2,100 to $7,900 more per year than the highest-tax states, depending on salary level (engine-computed range for $50,000–$100,000 salaries).
Overtime is taxed at the same rates as regular pay — there is no special overtime tax rate. However, the One Big Beautiful Bill Act of 2025 created a new federal deduction on the overtime premium portion up to $12,500 per year for single filers, claimed on your annual tax return rather than withheld on each paycheck.
Filing status dramatically changes withholding. Married Filing Jointly has a $32,200 standard deduction versus $16,100 for single, nearly doubling tax-free income. A $75,000 salary pays about $4,640 in federal tax annually for MFJ versus $7,670 for single — a difference of over $250 per month in take-home pay.
