1. What is Qualified Business Income (QBI)?

Qualified Business Income (QBI) is the net income from a qualified trade or business, used to calculate the QBI deduction under Section 199A of the Internal Revenue Code. This deduction allows eligible taxpayers to deduct up to 20% of their QBI.

2. How Does the Calculator Work?

The calculator uses the QBI calculation formula:

\[ QBI = Net Income - \left(\frac{1}{2} \times W2 Wages + 2.5\% \times UBIA\right) \text{ limit} \]

Where:

$ Net Income $ — Total business net income
$ W2 Wages $ — Total W-2 wages paid by the business
$ UBIA $ — Unadjusted Basis Immediately After Acquisition of qualified property
$ \frac{1}{2} $ — 50% wage component multiplier
$ 2.5\% $ — UBIA component percentage

Explanation: The calculation determines the deductible QBI amount by subtracting the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of UBIA from the net business income.

3. Importance of QBI Calculation

Details: Accurate QBI calculation is essential for maximizing tax deductions under Section 199A, ensuring compliance with tax regulations, and optimizing business tax strategy for pass-through entities.

4. Using the Calculator

Tips: Enter net income in dollars, W-2 wages in dollars, and UBIA (unadjusted basis) in dollars. All values must be non-negative numbers representing valid business financial data.
