BNA (subscription required) is reporting that Sen. Mary Landrieu (D-LA) has introduced an estate tax reform bill. Although not a full repeal and not as costly as Sen. Jon Kyl’s (R-AZ) compromise, it would still cost $245 billion over ten years. Sen. Landrieu’s bill calls for a $5 million per-spouse exemption with a rate of 35 percent that would increase for estates worth more than $10 million. Prompted by a request from Senate Majority Leader Bill Frist (R-TN), the House passed a version of estate tax reform similar to Kyl’s last week. However, Frist has failed to assemble the 60 votes needed to end debate, and so estate tax is stalled in the Senate. And Landrieu’s bill, if passed, might torpedo the whole estate tax repeal endevor as the conference report may not pass the House. When the House began debating Rep. Bill Thomas’ (D-CA) estate tax reform bill, he was ardent in his resistance to compromise: "This is not a first offer. It is the only offer to the majority leader's request the chairman intends to offer."
