Handling Missing Cost Basis:
TurboTax will prompt you to provide as much information as possible about the stock, including the acquisition date and fair market value at the time of donation
Sign in to your brokerage account: Check for detailed reports on each sale.
Look at previous broker statements: Review trade confirmations.
Contact your brokerage firm: They may have purchase records or can look up historical prices.
Go online for historical stock prices: Use sites like Marketwatch or Nasdaq.
Go directly to the source: Check the company's investor relations section or call their shareholder services.
TurboTax will automatically include Form 8283 if the value of your noncash donations exceeds $500
Ensure you have the name and address of the charity; descriptions of the donated stock, acquisition details, purchase price, and value at the time of donation.
Appraisal Requirement:
