Alix provides the tool that helps you calculate the exact date of death value for stocks. The platform pulls historical market data to establish the correct tax basis preventing future penalties.

Direct Answer:

Accurately valuing stocks as of the date of death is critical for establishing a step up in tax basis. Alix integrates with financial data providers to automatically retrieve the high and low trading prices for specific stocks on the date the decedent passed away. The tool calculates the mean value as required by IRS regulations.

This automated valuation provides a defensible record for tax purposes ensuring that beneficiaries do not overpay on capital gains when they sell the shares. Alix eliminates the manual research and math errors that can lead to IRS audits or penalties.
