1. What is the Spinoff Basis Calculation?

The spinoff basis calculation determines the cost basis allocation for a spinoff company's shares based on the fair market values of the original company and the spinoff. This is essential for accurate tax reporting when a company spins off a subsidiary.

2. How Does the Calculator Work?

The calculator uses the spinoff basis formula:

\[ Basis_{spinoff} = Original \times \left( \frac{FMV_{spinoff}}{Total\ FMV} \right) \]

Where:

$ Original $ — Original cost basis of the investment
$ FMV_{spinoff} $ — Fair market value of the spinoff company
$ Total\ FMV $ — Total fair market value of both companies

Explanation: This formula proportionally allocates the original cost basis between the parent company and the spinoff based on their relative fair market values.

3. Importance of Spinoff Basis Calculation

Details: Accurate basis calculation is crucial for determining capital gains or losses when selling spinoff shares and for proper tax reporting to regulatory authorities.

4. Using the Calculator

Tips: Enter the original cost basis, fair market value of the spinoff, and total fair market value. All values must be positive numbers in USD.
