§6166(a) Regular 14-Year Election
Voluntary Interim Payments Between Anniversary Dates
In this example the return was filed on the extended return due date 6 months after the statutory return due date. The following facts exist.
  • Form 4768 was filed on the return due date with a payment of $1,750,000, which was the amount of tax that was estimated would not be deferred under a §6166 election to be filed 6 months later
  • The return was filed 6 months later with a regular §6166(a) 14-year election. A maximum deferral election was made. No payment was due with the return. The non-deferred tax due on the return due date was $1,644,858.43, which was less than the $1,750,000 actually paid.
  • Pursuant to the §6166 maximum deferral election, the overpayment of $105,141.57 was treated as a prepayment of the tax payable in installments
  • An undesignated voluntary payment of $100,000 was made in 2018. Another voluntary payment of $150,000, designated as tax, was made in 2019.
  • Anniversary date interest payments were timely made in the amounts billed by Cincinnati Campus on February 10 each year through 2021. Installment payments of tax and interest were timely made in 2022 and 2023.

Interest overpayments are allocated to tax in the same manner as the undesignated payment on May-25-2018 in this example was applied to tax.

See the Period 3 allocations above. Occasional one-cent discrepancies are due to rounding.
