Summary

The Tax Court can make people pay money when a taxpayer starts or keeps a case just to delay things, when the taxpayer’s claim is clearly baseless, or when the taxpayer unreasonably skips available administrative steps. If a lawyer or other person needlessly drags out a case, the court can make that lawyer pay the extra costs, expenses, and attorney fees that caused. If the lawyer is arguing for the Commissioner of Internal Revenue, the United States may be made to pay those extra costs in the same way a district court would handle it. If a taxpayer brings a suit under section 7433 and the taxpayer’s position is frivolous, the court can fine the taxpayer up to $10,000. In other civil tax cases outside the Tax Court, money awards to the United States for sanctions, penalties, or costs can be assessed by the Secretary and collected like a tax. On appeal, an order from a Court of Appeals or the Supreme Court that awards money to the United States can be filed in a district court and enforced like any other district court judgment, and the Secretary may collect it like a tax.

(3)In connection with any appeal from a proceeding in the Tax Court or a civil proceeding described in paragraph (2), an order of a United States Court of Appeals or the Supreme Court awarding monetary sanctions, penalties or court costs to the United States may be registered in a district court upon filing a certified copy of such order and shall be enforceable as other district court judgments.
