What Is Section 909? Splitter Arrangements and Suspended Credits

Section 909 of the Internal Revenue Code is the foreign tax credit rule that suspends a credit whenever the person who pays a foreign tax and the person who reports the related income for U.S. purposes are not the same. The suspended tax stays frozen — uncreditable, and excluded from earnings and profits calculations — until the related income actually lands on a U.S. return.¹ The rule exists to shut down structures that would otherwise let a multinational group claim a Section 909 foreign tax credit years before the matching income shows up in the U.S. tax base.

The Splitting Event That Triggers Suspension

Everything in Section 909 turns on whether a “foreign tax credit splitting event” has occurred. The statute defines this in one line: a splitting event exists when the income related to a foreign tax payment is, or will be, taken into account by a covered person rather than by the person who paid the tax.¹ The focus is the person mismatch. Timing is not the trigger by itself.

When a splitting event exists, the foreign tax becomes a “split tax.” The related income is whatever income or earnings and profits the split portion of foreign tax relates to under the applicable splitter arrangement rules. Both amounts have to be tracked separately from the taxpayer’s normal foreign tax credit pools.

Who Counts as a Covered Person

Section 909 does not treat every unrelated-party mismatch as a splitting event. The other side of the transaction has to be a “covered person,” measured from the payor of the foreign tax. That covers:

Any entity in which the payor holds at least a 10 percent interest by vote or value, direct or indirect.
Any person holding at least a 10 percent interest in the payor.
Anyone related to the payor under the constructive ownership rules of Sections 267(b) or 707(b).
Any other person Treasury designates by regulation.

The 10 percent threshold and the related-party rules together sweep in most entities inside a controlled foreign corporation chain or a concentrated partnership structure.¹ If you are looking at a multinational group, assume the counterparties are covered persons and work from there.

The Splitter Arrangements That Cause Most Cases

Treasury regulations identify specific splitter arrangements that produce these mismatches. Three come up most often, and each depends on a difference between how the U.S. and a foreign jurisdiction classify an entity, an instrument, or a loss.

Reverse Hybrid Entities

A reverse hybrid is treated as a corporation for U.S. tax purposes but as fiscally transparent, like a partnership, under foreign law.² Because the foreign country looks through the entity, it taxes the U.S. owner directly on the income as it is earned. For U.S. purposes, the entity is a separate corporation, and the U.S. owner does not recognize that income until a distribution, a Subpart F inclusion, or a GILTI inclusion. The regulations treat a reverse hybrid as a splitter whenever the payor pays foreign tax on the reverse hybrid’s income.³

Loss-Sharing Arrangements

Many countries let affiliated companies share losses through group relief or consolidated returns. A loss-sharing splitter arises when one group member’s loss could have offset that same member’s own income, currently or in a prior year, but is instead used to offset another member’s income for foreign tax purposes. The group that surrendered the loss effectively reduced the foreign tax on income that, from the U.S. perspective, belongs to a different taxpayer.³ The U.S. system does not follow that cross-group offset, so the tax gets split.

Hybrid Instruments

Hybrid instrument splitters involve instruments treated as equity for U.S. purposes but debt under foreign law, or the reverse. In a U.S. equity hybrid instrument, the owner includes income for foreign tax purposes and the issuer takes a foreign deduction, but no matching income inclusion happens for U.S. purposes. A U.S. debt hybrid instrument runs the other way: the issuer pays foreign tax on income that, for U.S. purposes, is deductible interest.³ In either version, the tax and the related income sit with different persons for U.S. purposes.

How and When the Suspended Tax Is Released

Once a foreign tax is classified as a split tax, it cannot be credited, cannot be deducted for foreign tax credit purposes, and cannot enter earnings and profits until the related income is recognized.¹ There is no expiration date. The suspension continues indefinitely until the income event happens.

Release comes when the U.S. taxpayer takes the related income into account. The typical triggers are a dividend from the foreign entity, a Subpart F inclusion, a GILTI inclusion, or gain on the sale of the foreign subsidiary’s stock. When the income is recognized, a proportionate share of the suspended tax is released and treated as paid or accrued in the year of release.¹

CFCs, Partnerships, and Trusts

Section 909 has a dedicated subsection for specified 10-percent owned foreign corporations, which captures most CFCs. When a splitting event happens at the CFC level, the split tax cannot be taken into account for deemed-paid credit purposes under Section 960, and it is excluded from the CFC’s earnings and profits under Section 964(a) until the related income is recognized either by the CFC or by a U.S. shareholder.¹ Keeping the split tax out of those pools prevents it from inflating the deemed-paid credit calculation.

For partnerships, the suspension applies at the partner level, not the partnership level. The same partner-level approach extends to S corporations and trusts.¹ Each partner runs its own splitting-event analysis on its share of the partnership’s foreign taxes and related income, which adds real tracking work for partnerships with more than a handful of partners.

Overlap With Section 901(m) Covered Asset Acquisitions

Covered asset acquisitions run through Section 901(m), and Section 909 can layer on top. A covered asset acquisition happens when a transaction increases the U.S. tax basis of acquired assets without a matching increase in their foreign basis. The classic example is a Section 338 election that treats a stock purchase as an asset acquisition for U.S. purposes. Partnership interest acquisitions with a Section 754 election in place, and certain other transactions producing a U.S.-foreign basis mismatch, also qualify.⁴

Section 901(m) applies first. It calculates a “disqualified portion” of the foreign tax — the fraction attributable to the U.S. basis step-up — and permanently bars that portion from the foreign tax credit. The disqualified tax may still be deductible, but it will never be creditable.⁵ The basis difference is allocated over the asset’s U.S. cost recovery period, so the disqualification phases in with depreciation or amortization rather than hitting all at once.

Section 909 then runs on whatever survives. Foreign taxes that clear the 901(m) disqualification can still be suspended if the same transaction created a splitter arrangement. The common overlap is a covered asset acquisition involving a reverse hybrid, where both the basis step-up and the entity classification mismatch touch the same income. Complete the 901(m) calculation first, then apply 909 to what remains.

De Minimis Relief and What Section 909 Does Not Reach

Section 909 itself has no de minimis threshold. If a splitting event occurs, the tax is suspended regardless of the amount. The Section 901(m) rules do provide two safe harbors, and clearing them can eliminate both the 901(m) disqualification and any downstream 909 analysis for that transaction. A basis difference for any single relevant foreign asset is disregarded if its absolute value is less than $20,000. And the entire covered asset acquisition is exempt from Section 901(m) if the total basis differences across all relevant foreign assets are less than the greater of $10 million or 10 percent of total U.S. basis.⁶ These thresholds apply only in the covered asset acquisition context. A reverse hybrid, loss-sharing, or hybrid instrument splitter that does not involve a covered asset acquisition gets no safe harbor.

One boundary worth naming: Section 909 does not reach ordinary timing differences. A mismatch between U.S. and foreign depreciation methods, for example, does not create a splitting event, because the same entity is paying the tax and recognizing the income. The rule targets arrangements where the tax and the income land on different entities, not situations where one entity recognizes them on different schedules.

Pre-2011 Taxes Are Still in Scope

Section 909 was enacted in 2010 and generally applies to foreign taxes paid or accrued in taxable years beginning after December 31, 2010. The regulations also reach back. Pre-2011 split taxes are generally subject to suspension as of the first day of the taxpayer’s first post-2010 taxable year, and when suspended, they are removed from the post-1986 foreign income tax pools.⁷

Some pre-2011 taxes escape entirely: taxes already deemed paid under former Section 902 or Section 960 before the post-2010 effective date, taxes where the related income was already recognized before that date, and taxes paid in taxable years beginning before January 1, 1997.⁷ For groups with older international structures, this means the Section 909 review does not start cleanly in 2011. Splitter arrangements may need to be traced through historical tax pool data before the current-year analysis makes sense.
