US Payroll Guide 2026: Complete Gross-to-Net Paycheck Calculation for Employers & Employees

The Short Answer

A 2026 US paycheck is calculated in six ordered steps: (1) compute gross wages, (2) subtract pre-tax benefits (401(k), Section 125 health, HSA), (3) withhold federal income tax using the 2026 IRS brackets, (4) withhold Social Security at 6.2% up to the $176,100 wage base, (5) withhold Medicare at 1.45% (plus 0.9% over $200k), and (6) withhold state and local income tax. The remainder is your net pay — the number that hits your bank account.

2026 Federal Income Tax Brackets

The IRS adjusts brackets annually for inflation. The 2026 projections (single filer) are:

| Taxable Income | Marginal Rate |

|---|---|

| $0 – $11,925 | 10% |

| $11,925 – $48,475 | 12% |

| $48,475 – $103,350 | 22% |

| $103,350 – $197,300 | 24% |

| $197,300 – $250,525 | 32% |

| $250,525 – $626,350 | 35% |

| Over $626,350 | 37% |

Married filing jointly brackets are exactly double the single-filer bands through the 32% tier. The 2026 standard deduction is $15,000 (single), $30,000 (married), and $22,500 (head of household).

2026 FICA (Social Security + Medicare)

• Social Security: 6.2% employee + 6.2% employer, capped at the $176,100 wage base
• Medicare: 1.45% employee + 1.45% employer, no cap
• Additional Medicare surtax: 0.9% on employee wages over $200,000 (single) or $250,000 (married)

Self-employed workers pay both halves — 12.4% Social Security + 2.9% Medicare = 15.3% SECA — but deduct half above the line.

Pre-Tax Deductions That Lower Your Taxes

Not every deduction is created equal. The order matters:

• Section 125 (cafeteria plan) health premiums — reduce federal tax, state tax, and FICA
• Traditional 401(k) / 403(b) — reduce federal and state tax, but not FICA
• HSA (via payroll) — reduce federal, state, and FICA (triple advantage)
• Roth 401(k) — reduces nothing now (post-tax); tax-free in retirement
• Commuter benefits / parking (up to $325/mo in 2026) — reduce federal, state, and FICA

The Six-Step Paycheck Formula

```text

Step 1: Gross Wages = Hourly × Hours OR Salary ÷ Pay Periods

Step 2: − Pre-Tax Benefits (401k, health, HSA, commuter)

Step 3: − Federal Income Tax (2026 brackets, W-4 dependent)

Step 4: − Social Security (6.2% up to $176,100)

Step 5: − Medicare (1.45% + 0.9% surtax over $200k)

Step 6: − State + Local Tax

------------------------------------------

= Net Pay (Take-Home)

```

Worked Example — Hourly Worker in Texas

• Wage: $25/hour × 40 hours = $1,000/week gross
• Pay frequency: bi-weekly ($2,000/paycheck, $52,000/year)
• 401(k): $100 per paycheck ($2,600/year)
• Health premium: $75 per paycheck ($1,950/year)
• State: Texas (no income tax)
• Filing: single

Annualized calculation:

• . Gross: $52,000
• . Minus 401(k) $2,600 and health $1,950 → Federal taxable = $52,000 − $2,600 − $1,950 − $15,000 std ded = $32,450
• . Federal tax = 10% × $11,925 + 12% × ($32,450 − $11,925) = $1,192.50 + $2,463 = $3,655.50
• . Social Security on FICA wages ($52,000 − $1,950) = $50,050 × 6.2% = $3,103.10
• . Medicare = $50,050 × 1.45% = $725.73
• . State tax = $0 (Texas)

Annual take-home: $52,000 − $2,600 (401k) − $1,950 (health) − $3,655.50 − $3,103.10 − $725.73 = $39,965.67/year ≈ $1,537/paycheck.

Worked Example — Salaried Worker in California

• Salary: $85,000/year, paid semi-monthly ($3,541.67/paycheck)
• 401(k): 8% = $6,800/year
• Health premium: $2,400/year
• State: California (top marginal ≈ 9.3% at this income; effective is lower)

Federal: ($85,000 − $6,800 − $2,400 − $15,000) = $60,800 taxable → $7,912.50 federal tax.

FICA: ($85,000 − $2,400) = $82,600 → $5,121.20 SS + $1,197.70 Medicare.

California: ~6% effective on adjusted wages ≈ $4,700.

Estimated net: $85,000 − $6,800 − $2,400 − $7,912.50 − $5,121.20 − $1,197.70 − $4,700 ≈ $56,868/year ≈ $2,370 per semi-monthly paycheck.

States With No Income Tax (2026)

Nine states levy no income tax on wages in 2026:

• Alaska · Florida · Nevada · New Hampshire · South Dakota · Tennessee · Texas · Washington · Wyoming

Move from California to Texas at the same $85k salary and your take-home rises by roughly $4,700/year — but property tax, sales tax, and cost of living may claw some of that back.

Overtime and Your Paycheck

Overtime pay is calculated at 1.5× the regular rate for hours over 40 in a workweek under the FLSA (some states like California, Colorado, and Nevada apply daily thresholds too). Under Public Law 119-21 (the 2026 "No Tax on Overtime Act"), qualifying workers can deduct up to $12,500 single / $25,000 married of overtime premium pay from federal taxable income.

W-4 Withholding: Why Your Paycheck May Look Wrong

Federal withholding is estimated from your Form W-4 — not actual tax owed. Common reasons your paycheck under-withholds:

• Filed as single but really head of household
• Didn't claim dependents (Step 3) → $2,000 per child credit not applied
• Extra income (side gig, spouse's job) not entered in Step 2 or Step 4(c)
• Recently married but never updated the form

If you got a big refund last year, you over-withheld — update your W-4 to add allowances and boost every paycheck.

Payroll Compliance Checklist for Employers

• . Register with IRS for an EIN and each state you have employees in
• . Collect Form W-4 (federal) and state withholding form (e.g., CA DE-4, NY IT-2104)
• . Collect Form I-9 within 3 business days of hire
• . Verify Social Security number via SSNVS
• . Set up direct deposit authorization (or issue paper checks)
• . Register with state unemployment insurance (SUTA) — rates vary 0.3%–14%
• . Deposit federal tax (941/944) monthly or semi-weekly per IRS schedule
• . File Form 941 quarterly, W-2 annually
• . Comply with FLSA overtime (see our How to Calculate Overtime guide)
• 0. Post required DOL & state labor law posters

Frequently Asked Questions

How much of my paycheck goes to taxes in 2026?

For a median $60,000 single filer in a state with no income tax, expect ~18% total (federal + FICA). Add another 4–9% in high-tax states like California, Oregon, or New York.

Are bonuses taxed higher?

No — but they're withheld at a flat 22% federal supplemental rate (37% over $1M). Actual tax owed matches your ordinary bracket at tax time.

Do I pay FICA on my 401(k)?

Yes on traditional and Roth. FICA is applied before 401(k) deduction. Only Section 125 health premiums and HSA payroll contributions escape FICA.

What's the difference between exempt and non-exempt?

Non-exempt workers must be paid overtime; exempt (salaried, executive/admin/professional, earning ≥$684/wk in 2026) are not. See our FLSA exemption guide.
