About US Tax Portal & Methodology
US Tax Portal was engineered to bring speed, transparency, and clarity to everyday personal finance. While traditional financial calculators are burdened with heavy ad trackers, email gates, and slow loading times, our platform delivers instant, verifiable take-home pay calculations in milliseconds.
Our Calculation Methodology
Every estimate generated on our portal utilizes standard formulas derived directly from official government tax agencies:
1. Federal Income Tax
Computed using 2025/2026 IRS progressive tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) after automatically factoring in the standard deduction ($15,000 for single filers).
2. FICA Withholding
Integrates the mandatory 6.2% Social Security tax up to the statutory wage ceiling ($176,100 limit), alongside the standard 1.45% Medicare tax and 0.9% additional surtax over $200,000.
3. State Personal Income Taxes
Precisely mapped to individual state tax statutes across all 50 states — including 0% states (Texas, Florida, Washington, etc.), flat-tax states, and progressive tiered states.
4. Zero-Bloat Cloudflare Edge
Powered by Astro and Cloudflare's global edge network, delivering 100/100 Core Web Vitals performance with zero client tracking bloat.
