Partnership to Build America Act of 2013 - Establishes the American Infrastructure Fund (AIF) as a wholly-owned government corporation to provide bond guarantees and make loans to state and local governments and non-profit infrastructure providers for transportation, energy, water, communications, or educational facility infrastructure projects (Qualified Infrastructure Projects [QIPs]). Requires AIF also to make equity investments in QIPs such entities sponsor.

Directs the Secretary of the Treasury, acting through the AIF, to issue American Infrastructure Bonds with an aggregate face value of $50 billion. Requires proceeds from the sale of the bonds to be deposited into the AIF.

Amends the Internal Revenue Code to allow U.S. corporations to exclude from gross income qualified cash dividend amounts received during a taxable year from a foreign-controlled corporation equal to the face value of qualified infrastructure bonds the corporation has purchased.

Prohibits allowance of a foreign tax credit to the excluded portion of any dividend received by a U.S. corporation. Prohibits also the allowance of a deduction for expenses related to that excludable portion.
