(Sec. 2) Allows married couples who file a joint tax return to elect to conduct their business activities as a qualified joint venture without being treated as a partnership. Defines "qualified joint venture" as a trade or business entity in which the only members are a husband and wife who materially participate in such venture. Allows participating spouses to conduct their individual business activities as sole proprietors and divides their items of income and expense in accordance with their respective interests in such venture.

(Sec. 3) Requires the Secretary of the Treasury to notify a taxpayer of: (1) any unauthorized use of such taxpayer's identity (suspected identity theft) which the Secretary uncovers during an investigation of false statements or tax returns; and (2) any criminal charges brought against an individual who is using the identity of such taxpayer.

(Sec. 4) Extends from nine months to two years the period in which the Internal Revenue Service (IRS) may return property that has been wrongfully levied and for bringing a civil action for wrongful levy.

(Sec. 5) Allows taxpayers to recontribute to their individual retirement accounts (IRAs), without penalty or limitation, amounts that were wrongfully levied by the IRS. Requires the IRS to pay interest on IRA amounts that were wrongfully seized.

(Sec. 6) Allows the IRS to use any means of mass communication (e.g., the Internet) to publish unclaimed refund amounts.

(Sec. 7) Prohibits the Secretary from allowing the payment of taxpayer refunds to any refund anticipation loan business whose business practices are predatory.

Allow a transferor of a USRPI to furnish a non-foreign affidavit to a qualified substitute (i.e., a person responsible for closing the transaction involving a USRPI or the transferee's agent).
