OBBBA International Tax Changes in 2026

Today we're going to talk about something that affects virtually every US person with international operations, offshore investments, or cross-border structuring: the OBBBA international tax changes in 2026. The One Big Beautiful Bill Act, signed on July 4, 2025, was sold as a vehicle to make the 2017 TCJA provisions permanent. And it did that. But it also rewrote the rules for how the US taxes foreign earnings, export income, inbound payments, estates, and even remittances.

If you own a CFC, export goods or services, hold IP offshore, or are thinking about expatriating, the rules have shifted under your feet. Let's get into it.

GILTI to NCTI: The New Minimum Tax on Foreign Earnings

The biggest headline change first. GILTI (Global Intangible Low-Taxed Income) is dead. Long live NCTI (Net CFC Tested Income). And no, this is not just a rebrand.

Under the TCJA, the GILTI regime subjected the offshore earnings of US-owned Controlled Foreign Corporations to a minimum US tax. The Section 250 deduction was set at 50%, which against the 21% corporate rate produced a 10.5% effective rate on foreign CFC income. That deduction was scheduled to drop to 37.5% after 2025, which would have pushed the effective rate to 13.125%.

The OBBBA intercepts that sunset and permanently fixes the Section 250 deduction at 40%. The math: 21% x (1 - 0.40) = 12.6%. That's your new permanent effective NCTI tax rate. This was intentionally calibrated to sit just below the 15% Pillar 2 global minimum tax threshold while keeping a competitive edge for US-domiciled IP.

But here's the part that catches people off guard. The OBBBA completely eliminates the Qualified Business Asset Investment (QBAI) allowance. Under GILTI, your CFC's tax base was reduced by a deemed 10% return on tangible depreciable property. In other words, "routine" manufacturing returns from physical assets were carved out of what was supposed to be an "intangible" income tax. That exemption is gone.

What does this mean practically? If you run asset-heavy operations offshore (manufacturing, logistics, infrastructure), every dollar of net tested income now gets hit with the 12.6% rate. There is no more carve-out for physical capital. A CFC with $500 million in factory equipment used to shield $50 million annually from the GILTI base. Under NCTI, that $50 million shield evaporates entirely.

Now for some good news. The OBBBA significantly improves Foreign Tax Credit (FTC) mechanics for NCTI:

• FTC haircut reduced: Previously, only 80% of foreign taxes paid by your CFC were creditable against GILTI. The OBBBA bumps this to 90%. A CFC paying a 14% foreign effective tax rate (14% x 0.90 = 12.6%) generates enough credits to zero out your residual US NCTI liability entirely. That 14% number is your new magic benchmark for transfer pricing and supply chain structuring
• Expense apportionment eliminated: Under the TCJA, domestic interest expense and R&D expenditures were allocated to the GILTI basket, artificially depressing your FTC limitation. The OBBBA kills this. Interest and R&E expenses are now allocated strictly to US-source income, meaning your NCTI FTC limitation is calculated on the gross foreign inclusion without arbitrary reductions. If you've been dealing with stranded foreign tax credits for years, this is significant relief
• New PTI haircut: To prevent double-dipping, distributions of previously taxed NCTI income now face a 10% FTC haircut, effective for distributions after June 28, 2025

So how does this play out in practice? Let's say Company X has a CFC in Germany paying a 15% local rate. Under the old system, with the 20% FTC haircut and expense apportionment eating into the limitation, Company X was likely paying residual US tax on top of the German tax. Under NCTI, that 15% German rate (well above the 14% breakeven) combined with 90% creditability and zero expense allocation means Company X owes nothing additional to the US on those earnings. That's real, measurable cash savings.

FDII to FDDEI: The Export Incentive Gets a Makeover

Symmetrically, the OBBBA renames and restructures the US export incentive. Foreign-Derived Intangible Income (FDII) becomes Foreign-Derived Deduction Eligible Income (FDDEI). Notice the word "intangible" got dropped. That's not an accident.

The FDDEI Section 250 deduction is set at 33.34%, producing an effective rate of exactly 14% on qualifying export income (21% x (1 - 0.3334) = 14%). This is deliberately aligned with the 14% foreign tax rate that zeros out NCTI liability. Congress built a unified 14% target rate across the entire cross-border tax code. Say what you will about the politics, but the math is elegant.

The QBAI elimination actually works in your favor here. Under FDII, domestic manufacturers were penalized by their own capital investment: the more factories and equipment you owned in the US, the higher your "deemed tangible return," which reduced your FDII-eligible income. The OBBBA removes this entirely. If you're a domestic manufacturer exporting physical goods, you can now apply the 14% rate to your gross eligible export income without that arbitrary reduction tied to your domestic asset footprint.

What's the catch? For IP-heavy companies, the OBBBA explicitly excludes from the FDDEI base any income from:

• Sales, exchanges, or dispositions of intangible property
• Property subject to depreciation, amortization, or depletion
• Section 367(d) deemed transfers (IP migrations to foreign affiliates)

This is a direct hit on offshore IP migration strategies. Historically, a US company moving IP offshore via a Section 367(d) transfer could claim the FDII deduction on the resulting deemed royalty stream. Now that income gets taxed at the full 21% rate with no deduction.

The statute also includes a related-party anti-abuse rule: try to intercompany-transfer IP within a consolidated group before a foreign sale, and the property is still treated as "excludable" (hint: Congress saw that one coming).

However, standard royalty income from licensing IP to foreign third parties or affiliates from a US domicile remains fully eligible for the 14% FDDEI rate. The message is clear: keep your IP in the United States and license it outward. Move it offshore and you pay full freight.

BEAT Increases: The Inbound Minimum Tax

The Base Erosion and Anti-Abuse Tax, or BEAT, is the US's minimum tax on inbound investment. It targets multinationals that strip profits out of the US via deductible intercompany payments (royalties, interest, management fees) to foreign affiliates.

Under the TCJA, the BEAT rate was scheduled to jump from 10% to 12.5% in 2026. The OBBBA blocks that cliff and permanently sets the rate at 10.5% (11.5% for banks and securities dealers). While 10.5% is technically higher than the 2025 rate of 10%, it's meaningful relief compared to the 12.5% that would have otherwise kicked in.

Now I know what you're thinking: did Congress try to make BEAT even worse? Yes. The Senate proposed dropping the base erosion percentage threshold from 3% to 0.5% and eliminating the $500 million gross receipts safe harbor. Had that passed, virtually every cross-border operation in the US would have been caught in the BEAT net. The final law rejected those expansions entirely. The $500 million test and the 3% threshold (2% for financial institutions) remain intact.

Perhaps most importantly, the OBBBA makes permanent the favorable treatment of domestic tax credits under BEAT. The R&D credit, Low-Income Housing Tax Credit, Renewable Electricity Production Credit, and Section 48 Investment Credit can now permanently offset tax calculated under the BEAT regime. Without this fix, those credits would have been worthless for foreign-parented companies starting in 2026 because claiming them would have widened the BEAT gap, creating a phantom cash tax that completely defeated the purpose.

Estate and Gift Changes: $15 Million and the Shift to Income Tax Planning

The OBBBA permanently raises the federal estate, gift, and generation-skipping transfer (GST) tax exemptions to $15 million per individual ($30 million for married couples using portability), inflation-adjusted starting in 2027. The TCJA exemptions were temporary and set to sunset to roughly $6 million. The 40% top rate stays, and the step-up in basis at death under Section 1014 remains fully intact.

So what does this mean for you? For the vast majority of affluent families, federal estate tax is now a non-issue. The planning conversation shifts from "how do I avoid estate tax" to "how do I get income tax efficiency and basis management right."

This has immediate practical consequences for existing estate plans. If you have a credit shelter or bypass trust drafted under the old rules, you need to review it now. Funding a bypass trust up to the new $15 million maximum might not provide meaningful estate tax savings but could deny your surviving spouse the step-up in basis at death on those assets. That's an avoidable capital gains disaster for your heirs. Consider John and Sarah, a married couple with $25 million and a bypass trust drafted in 2018. Under the new exemption, that trust locks in John's original cost basis permanently, denying the step-up when Sarah passes. If the assets have $5 million in unrealized gains, their children face over $1 million in unnecessary capital gains tax. The fix is straightforward (a trust amendment or decanting), but only if you do it.

The OBBBA also enhanced Qualified Small Business Stock (QSBS) under Section 1202:

• Gross asset threshold: Raised from $50 million to $75 million for eligible issuers
• Gain exclusion cap: Increased to the greater of $15 million (inflation-adjusted) or 10x the taxpayer's basis
• Tiered holding periods: 50% exclusion for 3 years, 75% for 4 years, 100% for 5 years (for stock issued after July 4, 2025)

This is where the bill intersects directly with expatriation planning under Section 877A. The $15 million unified credit creates a powerful pre-expatriation gifting strategy. The "covered expatriate" net worth threshold remains fixed at $2 million. Execute a $13 million gift to a foreign trust before renouncing, and you drop below $2 million, entirely avoiding covered expatriate status and the mark-to-market exit tax. The IRS scrutinizes pre-expatriation gifts aggressively, so timing and documentation matter. Our cross-border advisory services cover the full sequence.

Other 2026 Section 877A thresholds: the average annual net income tax test rises to $211,000 (from $206,000), and the mark-to-market gain exclusion increases to $910,000 (from $890,000).

Remittance Excise: The 1% Tax on Outbound Transfers

The OBBBA introduces something entirely new to the Internal Revenue Code: a 1% excise tax on outbound remittance transfers under new Section 4475. We covered this in depth in our remittance tax guide, but here's the summary in context of the broader bill.

The tax applies to cross-border electronic funds transfers initiated using cash, money orders, cashier's checks, or similar physical instruments through a remittance transfer provider. It's assessed on the gross principal amount of the transfer, not the transmission fee. Early House drafts proposed rates of 3.5% to 5%. The final 1% rate was a compromise during Senate reconciliation.

The key exemptions protect banked individuals:

• Transfers funded via direct withdrawals from FDIC-insured banks, credit unions, or broker-dealers are exempt
• Transfers initiated using a US-issued credit card or debit card are exempt
• Standard bank-to-bank SWIFT transfers are exempt

In other words, if you're using a traditional bank account and doing a wire transfer, you're not affected. The tax targets cash-based remittance channels (think Western Union, MoneyGram) predominantly used by unbanked individuals sending money abroad.

The compliance burden falls on the remittance transfer provider. They must collect the 1% at the point of sale, remit semi-monthly, and report quarterly on Form 720. If a provider fails to collect, they assume secondary liability. The IRS issued Notice 2025-55 granting penalty relief for the first three quarters of 2026 while providers update their systems.

The statute also includes anti-conduit provisions under Section 7701(l) (hint: if you're thinking of routing cash through intermediary channels to dodge the 1%, the statute already anticipated that).

Impact on Existing Structures: What Breaks in 2026

If you have an existing cross-border corporate structure, several things changed simultaneously on July 4th, and the compounding effects can be serious. Let's walk through the biggest ones.

Section 163(j) and the death of the CFC group election. The OBBBA reverts the Adjusted Taxable Income (ATI) calculation to an EBITDA-based model, which is favorable for domestic businesses. But for multinationals, it requires you to subtract Subpart F income, NCTI inclusions, and Section 78 gross-ups from ATI.

This kills the "CFC group election" strategy. Under prior law, US parents routinely rolled up offshore GILTI and Subpart F inclusions into their domestic ATI base, expanding capacity to deduct domestic interest expense. That's over. Let's say Company X borrowed $1 billion domestically to acquire a European target. Previously, European earnings bolstered the ATI cap. Now those foreign inclusions are excluded from ATI, and Company X faces interest deduction disallowances that may require migrating debt down to the operating CFCs to align deductions with local taxable income.

Downward attribution fix and Section 951B. The OBBBA restores the Section 958(b)(4) limitation on downward attribution, fixing the TCJA-era problem where foreign-owned corporate groups saw their non-US subsidiaries accidentally classified as CFCs. A US subsidiary of a foreign parent will no longer be deemed to own the stock of sibling foreign entities via blind attribution.

But Congress simultaneously enacted Section 951B to prevent multinationals from exploiting this fix with domestic "blocker" entities. Section 951B creates a parallel inclusion regime ensuring US entities in foreign ownership chains remain fully subject to NCTI and Subpart F inclusion based on their economic control. As you can see, they closed the loophole and the workaround at the same time.

Pro rata share inclusion timing. Under old rules, Subpart F and GILTI inclusions were recognized on the last day of the CFC's tax year. Sellers could dump CFC stock on December 30th and shift the entire year's inclusion to the buyer. The OBBBA eliminates this "last day" rule. Now, if a foreign corporation is a CFC at any point during its tax year, every US shareholder who held stock during that year must recognize their pro rata share based on the exact number of days they held the equity.

This completely rewrites cross-border M&A structuring. Purchase agreements now need interim financial closings and tax indemnities. A seller disposing of a CFC on June 30th will owe NCTI on exactly 50% of the CFC's annual income, and they'll need the buyer to provide full-year financials the following spring to comply.

On the positive side, the OBBBA permanently extends the Section 954(c)(6) CFC "look-through rule," allowing dividends, interest, rents, and royalties between related CFCs to be excluded from Subpart F income when attributable to active business operations. If you're managing a multi-entity offshore structure with trusts, this permanence is a critical lifeline for moving cash between subsidiaries without triggering phantom US tax.

The OBBBA international tax changes in 2026 are not incremental adjustments. They are structural rewrites of rules that have governed cross-border planning since 2017. If you have existing CFC structures, offshore IP, debt-funded acquisitions, or estate plans drafted under the TCJA, each one needs to be modeled against your specific facts. The opportunities are real: improved FTC mechanics, QBAI elimination benefiting exporters, $15 million exemptions. But so are the traps: expanded NCTI base, destroyed CFC group elections, IP migration penalties. The structures that worked in 2025 may produce very different results in 2026 without recalibration.
