The IRS can apply corporate income tax payments in excess of the regular tax liability to the full amount of the taxpayer's mandatory repatriation tax, even where the taxpayer has elected to pay that tax over eight years pursuant to Section 965(h).
Holding
The U.S. Court of Federal Claims held that Pitney Bowes Inc.’s entire $24.4 m mandatory repatriation tax liability was part of its 2017 income tax liability, even though the company had elected to pay the tax in instalments through to 2025. The IRS therefore correctly retained $21.4 m of the excess tax payments and applied them against the outstanding repatriation tax liability without any payment of overpayment interest.
Judge Carolyn N. Lerner granted the Government's motion for summary judgment and denied Pitney Bowes' motion for partial summary judgment.
The ruling dismissed the company's claim for at least $3.12m in interest.
Why It Matters
First judicial resolution of the specific issue. The Court identified the treatment of overpayment interest under the Section 965(h) installment election as a first-impression issue. Other disputes involving United Parcel Service and Wells Fargo were pending before the same Court.
Installment elections do not separate the underlying tax liability by year. Section 965(h) allows taxpayers to spread payments across eight years. It does not divide the original tax liability into separate annual liabilities for purposes of determining whether an overpayment exists.
Refund and interest calculations depend on total liability. Taxpayers cannot establish a refundable overpayment merely because their estimated payments exceed their income tax liability calculated without Section 965. The calculation must include the full repatriation tax liability.
Late IRS guidance does not change the statutory result. The Court acknowledged that the IRS announced its overpayment-retention policy only four days before the first installment deadline. Nevertheless, the statutory treatment controlled.
The decision addresses the interaction between Sections 965, 6402, 6403, and 6611. It does not invalidate Section 965(h) installment elections or impose underpayment interest on timely installments.
Key Facts
Congress enacted Section 965 as part of the Tax Cuts and Jobs Act on December 22, 2017. The provision imposed a one-time mandatory repatriation tax on certain previously untaxed foreign earnings attributable to U.S. shareholders.
Pitney Bowes held interests in foreign corporations with accumulated untaxed earnings and reported the resulting liability on its 2017 federal income tax return.
Its tax position included:
Regular 2017 income tax liability, excluding repatriation tax: $4,493,046.
Payments exceeding regular income tax liability: $36,227,230.
Total Section 965 liability: $24,390,637.
First installment required under Section 965(h): $1,951,251.
Actual designated first installment payment: $3,000,000.
Additional payment credited toward the second installment: $1,048,749.
Excess payments the IRS retained against the remaining Section 965 liability: $21,390,637.
Overpayment interest sought by Pitney Bowes: at least $3,124,262.11.
Pitney Bowes elected to pay its repatriation tax in eight annual installments rather than paying the full amount with its 2017 return.
The company requested a refund of the $36.2 million that exceeded its regular income tax liability. The IRS instead refunded only part of that amount and applied $21.4 million to the remaining repatriation tax installments scheduled from 2019 through 2025.
The dispute arose partly from the timing of IRS guidance. On March 13, 2018, the IRS instructed taxpayers to make separate payments for their regular income tax and Section 965 liabilities.
On April 13, 2018, the IRS issued revised guidance explaining that it would retain excess regular income tax payments and apply them against future Section 965 installments. The announcement came four days before the April 17, 2018, first installment deadline.
An August 2, 2018, IRS technical advice memorandum further explained that taxpayers could not have an overpayment for 2017 until they had satisfied their entire income tax liability, including amounts subject to the Section 965(h) installment election.
Pitney Bowes filed suit on April 14, 2025. Both parties agreed that the material facts were undisputed and sought judgment on the legal question.
Statutory and Regulatory Framework
Section 965(a) imposed a one-time inclusion of certain accumulated foreign earnings in income for the applicable transition tax year.
Section 965(h) allowed taxpayers to elect to pay the resulting net tax liability in eight annual installments. The payment schedule required 8% of the liability in each of the first five years, 15% in the sixth year, 20% in the seventh year, and 25% in the eighth year.
Section 6315 treats estimated income tax payments as payments toward income taxes imposed under Subtitle A of the Internal Revenue Code, which includes Section 965.
Section 6402(a) authorizes the IRS to credit an overpayment against a taxpayer’s other federal tax liabilities.
Section 6403 governs overpayments involving installment taxes. It requires applying excess installment payments to unpaid installments before allowing the remaining amounts to be credited or refunded under Section 6402.
Section 6611 provides interest on tax overpayments. For amounts applied as credits, Section 6611(b) generally measures interest from the overpayment date through the due date of the liability receiving the credit.
Treasury Regulation Section 301.6611-1(b) generally prevents recognition of a tax overpayment until the taxpayer has satisfied the entire tax liability.
The central distinction concerns the difference between the tax imposed for a particular year and the dates on which Congress permits payment.
Arguments
Pitney Bowes argued:
Section 965(h) established separate payment dates for the eight installments. Only the first installment was payable in April 2018.
Payments that exceeded the regular 2017 income tax liability and the first repatriation tax installment constituted an overpayment eligible for a refund or interest.
Section 6403 did not authorize the IRS to apply payments originally designated for regular income tax against future repatriation tax installments.
Section 6402 permitted credits only against liabilities that had become due, not installments with future payment deadlines.
The IRS’s separate payment instructions supported treating regular income taxes and repatriation tax installments independently.
The absence of underpayment interest on timely repatriation tax installments supported treating those amounts as not yet due.
Section 6611 required compensation for the period between the original excess payment and each subsequent installment payment date.
The government argued:
Section 965 imposed the full repatriation tax liability for a single tax year. The installment election changed payment timing without changing when the underlying liability arose.
Estimated payments for 2017 applied toward the taxpayer’s entire income tax liability, including Section 965.
Sections 6402 and 6403 authorized the IRS to retain excess payments and apply them against unpaid repatriation tax installments.
No overpayment existed for purposes of Section 6611 while part of the taxpayer’s total 2017 liability remained unpaid.
Congress separately governed underpayment and overpayment interest and did not require identical treatment.
Court’s Reasoning
1. The entire repatriation tax liability belonged to one tax year. Section 965(a) required taxpayers to include certain accumulated foreign earnings in income for the applicable transition tax year. The statute did not distribute that income inclusion across the eight installment years. Pitney Bowes reported its entire $24,390,637 repatriation tax liability on its 2017 return. Judge Lerner concluded that Section 965(h) changed when the taxpayer could satisfy that liability but did not change the tax year to which it belonged.
2. Congress expressly provided different treatment for real estate investment trusts. The Court compared Section 965(h) with Section 965(m), which established special rules for real estate investment trusts. Section 965(m) expressly permitted qualifying trusts to include portions of their repatriation tax income over eight separate years.
Congress did not include comparable language in Section 965(h). The difference supported the conclusion that an ordinary Section 965(h) election deferred payments without distributing the underlying income inclusion across future years.
3. Existing installment-tax decisions supported the IRS’s treatment. The Court relied on three decisions involving tax liabilities payable in installments. In Blair v. United States ex rel. Birkenstock, the Supreme Court ruled that paying more than a scheduled installment did not create a refundable overpayment while the taxpayer still owed part of the total annual tax. In Matson Navigation Co. v. United States, the Court of Claims similarly determined that an overpayment did not exist until payments exceeded the taxpayer’s total tax liability. In Estate of Bell v. Commissioner, the Ninth Circuit permitted the IRS to apply excess payments from earlier installments against future estate tax installments.
Judge Lerner considered these decisions consistent with the statutory distinction between an installment payment and satisfaction of the full tax liability.
4. Sections 6402 and 6403 authorized the application of excess payments. Pitney Bowes argued that Section 6403 applied only to amounts specifically paid as installments of the repatriation tax. The Court rejected that reading. Section 6315 treats estimated income tax payments as payments toward income taxes imposed under Subtitle A. Section 965 falls within that subtitle. Section 6403 also addresses amounts paid toward the total tax liability, regardless of whether the taxpayer originally paid them as installments.
The Court further concluded that Section 6402 supplied independent authority to apply qualifying overpayments against other tax liabilities. Together, these provisions supported the IRS’s allocation of Pitney Bowes’s payments to the remaining repatriation tax liability.
5. Future installment dates did not prevent the IRS from recognizing the underlying liability. Pitney Bowes emphasized that Section 965(h) specified dates when each installment had to be paid. The company also relied on statutory acceleration provisions that make remaining installments immediately payable after certain events, such as a cessation of business.
Judge Lerner distinguished the payment timing from the year Congress imposed the liability. An acceleration event changes when the IRS can require payment of the remaining installments. It does not establish that the underlying tax liability arose separately in each installment year.
The Court also rejected the company’s reliance on Fruehauf Corp. v. United States, which concerned the treatment of deficiency interest under a different regulatory framework. Unlike the contingent interest liability in Fruehauf, Pitney Bowes’s repatriation tax liability was fixed when it filed its 2017 return.
6. The absence of underpayment interest did not establish a right to overpayment interest. Section 965(h) allows taxpayers to pay scheduled installments without incurring underpayment interest merely because they have not paid the entire liability immediately. Pitney Bowes argued that the government could not treat the entire tax as an existing liability for overpayment purposes while allowing later installment payments without interest.
The Court rejected that argument because Sections 6601 and 6611 separately govern interest on underpayments and overpayments. Congress could authorize interest-free installment payments without requiring the IRS to pay interest on funds applied against the outstanding tax.
The Court relied on Marsh & McLennan Cos. v. United States for the principle that the tax code does not require symmetrical treatment of underpayment and overpayment interest.
7. The timing of IRS guidance did not override the statute. The Court acknowledged that the IRS’s rollout created practical difficulties. The agency announced its policy of retaining excess payments on April 13, 2018, only four days before the initial installment deadline. Taxpayers who expected refunds or credits against their 2018 estimated payments could therefore face unexpected payment shortfalls.
Nevertheless, the Court concluded that the statutory provisions authorized the IRS’s treatment. The late announcement and separate payment instructions did not create an entitlement to overpayment interest.
Result
The Court of Federal Claims granted summary judgment for the United States, denied Pitney Bowes’s motion for partial summary judgment, and directed the clerk to enter judgment, rejecting the company’s claim for at least $3,124,262.11 in overpayment interest.
The Takeaway
The decision makes a significant distinction for taxpayers who have elected installment payments under section 965(h) in that deferring the payment of tax does not constitute a deferral of the recognition of the tax liability for the purposes of computing overpayments and interest.
Its immediate relevance extends beyond Pitney Bowes because similar questions were pending in United Parcel Service, Inc. v. United States, No. 25-641, and Wells Fargo & Co. v. United States, No. 26-557.
The decision comes from a trial court and doesn't in any way resolve those separate proceedings or create binding appellate precedent.
