Summary

Lets a court decide disputes about using the special payment plan under section 6166 for paying estate tax, or whether that plan has stopped applying to an estate or to property in the estate. Only the person in charge of the estate (the executor) or someone who agreed to make the 6166 payments may bring the case. If more than one person agreed to pay, they all must be joined in the case. The court will not act until the person has used all IRS steps to get a decision. If the IRS does not decide, the person is treated as having exhausted IRS steps after 180 days if they tried in a timely way to get the decision. If the IRS sends its decision by certified or registered mail, any case must be filed before the 91st day after that mailing. The normal 2-year time limit to sue for a tax refund is paused during the 90-day period after that mailing and, if a Tax Court case is filed under this rule, until the Tax Court’s decision becomes final.
