How do I determine the cost basis?”---> I guess you can visit the websites of the stock company(ies) whose stock you received as a gift and check the investor relations section. Many companies display historical stock information, such as price and dividends paid on specific dates. If the company doesn't have the information, then you can also go to a financial website that provides stock price and dividend history.
