About OBBB Tax Guide
A free calculator to help working Americans understand and claim their OBBB deductions.
Our Mission
The One Big Beautiful Bill Act represents the most significant tax reform for working Americans in decades. However, complex legislation often means that eligible taxpayers miss out on savings simply because they don't understand what they're entitled to claim.
OBBB Tax Guide was created to bridge that gap. We provide clear, accurate information about each OBBB deduction and an interactive calculator that walks you through the process step-by-step.
Our goal is simple: ensure every working American can easily understand and claim the tax savings they've earned.
Who We Are
OBBB Tax Guide was built to solve a simple problem: the IRS released Schedule 1-A on March 2, 2026, and millions of workers are eligible for new deductions they don't fully understand. We built a free calculator that handles all the edge cases — phase-outs, filing status limits, and deduction interactions — so you can see exactly what you're owed.
Our calculator is based on the official IRS Schedule 1-A instructions (IR 2026-28) and is regularly updated as new guidance is released. We cover all six OBBB deductions in one place — most other tools only handle overtime.
