Frequently asked questions
- Who is responsible for tracking cost basis? Individual taxpayers are responsible for tracking the cost basis of their noncovered investments and for calculating and reporting the holding period and any realized gain or loss on the sale of those investments.
- What happens if you don’t know the cost basis of a stock? The IRS expects you (the shareowner) to maintain records that identify the cost basis of your securities. If you don’t have adequate records, you might have to rely on the cost basis that your brokerage firm reports, or you may be required to treat the cost basis as zero, which could mean owing more in taxes.
- Does a company legally have to provide cost basis information to shareowners? Yes, a company is legally required to provide cost basis information to shareholders for shares purchased on or after January 1, 2011 due to regulations enacted by the Emergency Economic Stabilization Act of 2008. This means brokers, mutual funds and other financial institutions must report the cost basis of securities to their clients, including on Form 1099-B for tax purposes.
- Does a company legally have to provide cost basis information to shareowners prior to January 2011? No, a company was not legally required to provide cost basis information to shareholders before January 1, 2011. The mandatory cost basis reporting rules for brokers and transfer agents only came into effect on that date due to legislation passed in 2008. This means any shares acquired before January 1, 2011 are considered “noncovered” and do not require cost basis reporting.
- What if I can’t find the cost basis of old stock? You can call the company’s shareholder services department for help. For shares purchased more than 10 years ago, public libraries or law school libraries will have back issues of newspapers such as USA Today. Use these back issues to find the high and low price on the date of purchase.

Important information about protecting your Alliant Energy Corporation stock from escheatment:
Alliant Energy Corporation is required to “escheat” (report and transfer to a state unclaimed property division) your shares in Alliant Energy Corporation and/or uncashed dividend checks if they are considered abandoned property under relevant state law. Several factors might cause your shares and/or dividend checks to be considered abandoned property, such as: returned mail, lack of contact with our transfer agent (EQ Shareowner Services) on an annual basis, or uncashed checks. Once your shares and/or dividend funds have been escheated, you will need to file a claim with the relevant state for the return of your property.
What can you do to help prevent the escheatment of your shares/dividends? Maintain activity on your account via annual communication with EQ Shareowner Services either by phone, mail, email, or by logging into your shareowner account on their website at shareowneronline.com to verify your account information. In some states, voting your proxy also counts as contact for unclaimed property purposes. Please be sure to keep your address up to date and promptly cash all dividend and sale proceeds checks.
Did you receive a letter from EQ Unify? The letter is legitimate. It is legally-required due diligence to contact shareowner accounts with no shareowner-initiated activity for at least three years. Dividend reinvestment or ACH deposit of cash dividends is not considered shareowner-initiated activity.
To keep your account active, please call EQ Shareowner Services Customer Care at 1-800-356-5343 immediately. Provide your account number and let the representative know you are calling to make contact and keep your account active.
Moving forward, you will need to make contact annually to keep your account active. Other forms of shareowner-initiated activity include an additional voluntary cash contribution and submitting an account authorization form to make updates to your account (e.g., banking information, automatic investments, change dividend reinvestment election, update address, sign into your account online).
