Section 6166(h) Example 1 - Deficiency generated entirely by a 6166 value increase where zero tax was originally assessed

 

Section 6166(h) - Example 1

Feb-17-2016Date of death
Nov-17-2016Estate tax return due date and the return filing date. The return reports a taxable estate of $5,124,400 (which in this example is also the §6166(b)(6) adjusted gross estate) and zero estate tax due. A closely held business is included in the gross estate at a value of $3,000,000, but neither a §6166 election nor a protective §6166 election is filed with the return.
 NOTE: With these figures the §6166(a)(2) ratio for the maximum amount of tax which may be paid in installments is 58.5434%, which equals zero tax payable in installments for the return as filed (58.5434% of $0.00 tax = $0.00 payable in installments).
Apr-26-2018An IRS field examination is completed. The only changes are an increase in the value of the closely held business interest to $5,500,000 and a new Schedule J deduction for $10,794.24 deductible interest, which results in a deficiency of $856,442.30. The Estate agrees to the proposed deficiency by signing a waiver, Form 890. The Estate also files a §6166(h) election for the deficiency with the examining IRS Estate Tax Attorney and submits a catch-up payment to the Attorney to bring the account current under the §6166(a) election (made via the §6166(h) election) as of that date.
 The 1st anniversary date under the §6166(a) election was Nov-17-2017, when interest only was due (the 1st installment of tax will be due Nov-17-2021).
 

The catch-up payments due on Apr-26-2018 are:

  • the non-deferred tax, plus interest at R% thereon calculated from the return due date of Nov-17-2016 to Apr-26-2018;
  • the special-rate interest on deferred tax that would have been due on the 1st anniversary date of Nov-17-2017; and,
  • interest at R% on the unpaid special-rate interest due on the 1st anniversary date, calculated from the §6166(a) interest payment due date of Nov-17-2017 through Apr-26-2018.
 While 100% of the deficiency is attributable to the closely held business interest, §6166(a)(2) limits the portion of the deficiency that may be paid in installments to 72.1368% of the total. This methodology is explained in PLR 8846001.
This example illustrates that the §6166(a)(2) ratio determines the maximum amount of tax and the maximum amount of a deficiency that may be paid in installments, and only when the §6166(a)(2) ratio equals 1.000000 (100%) will 100% of a deficiency be eligible under a §6166(h) election to be paid in installments. This is in keeping with the principles outlined in PLR 8846001.
