1. What Is Unadjusted Basis For QBI?

The Unadjusted Basis is a key calculation for Qualified Business Income (QBI) deductions under Section 199A. It represents the original cost of qualified property minus any accumulated depreciation, used to determine the deduction limit for pass-through businesses.

2. How Does The Calculator Work?

The calculator uses the Unadjusted Basis formula:

Where:

• \( \text{Cost} \) — Original acquisition cost of the asset (USD)
• \( \text{Depreciation} \) — Total accumulated depreciation taken on the asset (USD)
• \( \text{Unadjusted Basis} \) — Resulting basis used for QBI calculations (USD)

Explanation: This calculation determines the unadjusted basis immediately after acquisition of qualified property, which is crucial for determining the W-2 wage and qualified property limitation under Section 199A.

3. Importance Of Unadjusted Basis Calculation

Details: Accurate unadjusted basis calculation is essential for maximizing QBI deductions, ensuring tax compliance, and proper tax planning for small businesses and pass-through entities. It affects the deduction limit calculation for specified service trades and businesses.

4. Using The Calculator

Tips: Enter the original cost of the qualified property and the total accumulated depreciation in USD. Both values must be non-negative numbers. The calculator will compute the unadjusted basis for QBI purposes.

5. Frequently Asked Questions (FAQ)
