Every English-language article about GILTI stops at the US border. They explain IRC §951A, walk through the §962 election, and leave US citizens abroad thinking the problem is solved once the US return is filed. If you live in Spain, that is half the story — and the missing half costs real money. Spain runs its own parallel anti-deferral regime under Art. 91 LIRPF, amended by Ley 11/2021 to align with ATAD II. A US citizen who owns a Delaware C-Corp and moves to Madrid can face simultaneous inclusion events on two tax returns, in two countries, with only partial credit relief available. This article covers the intersection that nobody else is writing about.
1. Why GILTI articles ignore Spain — and that’s expensive
I’ve reviewed every major English-language article ranking for “GILTI expat” and “GILTI Spain.” Greenback, Bright!Tax, 1040Abroad, ExpatTax Professionals — they are all US-first. They cover the mechanics of IRC §951A, explain why the §962 election matters for individuals, and walk through Form 5471 filing obligations. Not one of them mentions Art. 91 LIRPF.
That gap is understandable from a US CPA perspective. Their client’s Spanish tax return is someone else’s problem. But for the US citizen who is now a Spanish tax resident — who files both an IRS Form 1040 and a Spanish Modelo 100 each year — “someone else’s problem” is still their problem. Two inclusion events, two tax charges, one set of assets. The Foreign Tax Credit coordination between the two systems is not automatic, not clean, and not self-executing.
The practical consequence: founders who incorporated a Delaware C-Corp before their Barcelona relocation, tech executives who hold offshore holdcos, and HNWI investors with Cayman fund structures frequently discover the Spain CFC exposure only at tax season — after the window to restructure has closed. Pre-move modeling across both regimes is not optional. It is the difference between a manageable effective rate and a rate that exceeds the economics of the underlying investment.
2. GILTI basics: IRC §951A, who triggers, and the effective rate
GILTI — Global Intangible Low-Taxed Income — was introduced by the Tax Cuts and Jobs Act of 2017 and codified at IRC §951A, effective for taxable years beginning after 31 December 2017.
Who is caught. Any US person (IRC §957(c)) who is a US shareholder — meaning a US citizen, green card holder, or US-resident alien who owns, directly or indirectly, ≥10% of the total combined voting power or value of a CFC — must include their pro-rata share of the CFC’s GILTI in gross income for the year. Ownership is measured under the attribution rules of IRC §958.
What is GILTI. GILTI is defined as the excess of the US shareholder’s net CFC tested income over a net deemed tangible income return (NDTIR): 10% of the CFC’s qualified business asset investment (QBAI). In plain terms: GILTI = passive-like income of CFCs that earns a return above 10% on tangible assets. For holding companies, IP boxes, or service CFCs with minimal fixed assets, the QBAI deduction is near zero — GILTI inclusion approaches 100% of net income.
The individual rate problem. For an individual US taxpayer without the §962 election, GILTI is included as ordinary income at up to 37% federal marginal rate, with no §250 deduction available. The §250 deduction — which reduces GILTI inclusion by 50% (37.5% after 2025 under TCJA sunset projections) — is available only to domestic corporations under the statute as written.
The corporate effective rate. A domestic C-Corp receiving GILTI takes the §250 deduction, reducing the inclusion to 50% of GILTI. At 21% corporate rate, effective GILTI tax = 10.5%. A deemed-paid Foreign Tax Credit under §960(d) — limited to 80% of foreign taxes paid — applies on top, potentially reducing the effective rate further. The §250 deduction percentage is scheduled to fall to 37.5% post-2025 under current TCJA sunset rules, raising the corporate effective rate to approximately 13.125%. Legislative outcome remains uncertain as of May 2026.
3. The §962 election: mechanics, deadline, and Form 8993
IRC §962 was enacted in 1962 — long before GILTI existed — to prevent US individuals from being taxed more harshly than US corporations on CFC inclusions. Post-TCJA, it has found new life as the primary rate-reduction tool for individual GILTI taxpayers.
What §962 does. An individual US shareholder makes an election under IRC §962(a) to be treated, solely for purposes of Subpart F inclusions (including GILTI, which is treated as a Subpart F-like inclusion for most purposes), as if the amounts were received by a domestic corporation. The consequences:
- The §250 deduction becomes available, reducing GILTI inclusion by 50% (current law).
- The deemed-paid Foreign Tax Credit under §960(d) becomes available — limited to 80% of CFC-level foreign taxes attributable to the GILTI inclusion.
- The net inclusion is taxed at the corporate rate (21%), not the individual marginal rate.
The second-level tax trap. §962(d) provides that if the earnings underlying the §962 inclusion are later actually distributed to the individual, the distribution is taxed again as dividend income — with a partial credit for tax already paid under the §962 election. This second-level tax means the §962 election defers some tax rather than eliminates it. For US citizens in Spain, that deferred second-level tax will be paid on the Spanish Modelo 100 as well (as a qualified dividend or, if the Treaty applies, at the Treaty rate).
Deadline and mechanics. The §962 election is made on the individual’s federal income tax return for the year to which the election applies. There is no separate stand-alone form — the election is made by attaching a statement identifying: (a) each CFC to which it applies; (b) the total Subpart F/GILTI income included; and (c) the §960 deemed-paid credit claimed. Form 8993 must also be attached to compute the §250 deduction. The election is annual — it must be renewed each year; it does not carry forward automatically.
Treasury Regulations. The §962 election mechanics are governed by Treas. Reg. §1.962-1 through §1.962-3. The interaction with GILTI is addressed in Treas. Reg. §1.951A-1 through §1.951A-7 and the GILTI high-tax exclusion at Treas. Reg. §1.951A-2(c)(7).
4. Spain’s parallel CFC regime: Art. 91 LIRPF + Art. 100 LIS after Ley 11/2021
Spain has operated a transparencia fiscal internacional (TFI) — CFC — regime since Ley 43/1995. The regime was substantially overhauled by Ley 11/2021, de 9 de julio (BOE-A-2021-11473), which transposed the EU Anti-Tax Avoidance Directive II (ATAD II, Directive 2017/952/EU) into Spanish law, effective 1 January 2021.
Two parallel tracks:
- Art. 91 LIRPF — applies to Spanish-resident individuals. If conditions are met, the individual must include in their IRPF base the undistributed positive income of the non-resident entity, attributed in proportion to their ownership.
- Art. 100 LIS — applies to Spanish-resident companies. Parallel mechanics but integrated into corporate income tax (IS). Relevant when the holding structure involves a Spanish SL interposed between the individual and the CFC.
The four cumulative conditions under Art. 91 LIRPF (post Ley 11/2021):
-
Control threshold: the individual holds, directly or indirectly, ≥50% of the share capital, voting rights, assets, or profit-participation rights of the non-resident entity. Note: this is 50%, not the 10% US shareholder threshold under IRC §957 — but in founder and HNW scenarios (100% ownership being common), both thresholds are met simultaneously.
-
Low-tax test: the effective tax rate borne by the entity in its country of residence is less than 75% of what would have been due under Spanish corporate income tax (IS) rules on the same income. The IS general rate is 25%, so the threshold is an effective rate of less than 18.75% in the foreign jurisdiction. A Delaware C-Corp paying US federal corporate tax at 21% on its profits clears this threshold — but only if its effective rate (after deductions, credits, and GILTI offsets) is actually ≥18.75%. In many cases involving IP, loss carryforwards, or R&D credits, the effective US rate at the entity level is lower.
-
Passive income: the entity earns qualifying passive income — dividends, interest, royalties, income from leased real estate, capital gains from financial assets, insurance income, and income from finance and credit operations. The list was expanded by Ley 11/2021 relative to the pre-ATAD II version.
-
Passive income threshold: passive income items listed in Art. 91.3 LIRPF together exceed 15% of the entity’s total income for the tax period (Art. 91.4 LIRPF). Note: the “dos tercios” (two-thirds) figure appearing in Art. 91.3.i is a separate unrelated-parties exclusion for financial/service income — not the de minimis floor.
All four conditions must be met simultaneously. If the C-Corp earns principally active trading income and passive income is below 15% of total (Art. 91.4 LIRPF de minimis), Art. 91 LIRPF does not trigger — even if conditions 1, 2, and 3 are individually satisfied.
Post-2021 changes that matter. Pre-Ley 11/2021, the low-tax test used a nominal rate comparison. Post-2021, it uses effective rate — a much tighter standard. Additionally, the “valid commercial reasons with economic substance” defense (analogous to the US check-the-box purpose doctrine) was tightened: the entity must demonstrate real economic activity in its country of residence, with genuine human and material resources, and the structure must not have been set up primarily to achieve a tax advantage.
5. The double-exposure trap: concrete math
Let us run the numbers on a realistic scenario.
Facts: Alex is a US citizen. He owns 100% of a Delaware C-Corp (“AlphaCorp”). AlphaCorp earns $200,000 of passive income (interest on loans and dividends from portfolio investments) in calendar year 2025. AlphaCorp pays zero US corporate income tax because it has sufficient R&D credit carryforwards. Alex has been a Spanish tax resident since January 2025 (under the general LIRPF regime — not Beckham).
US side — GILTI inclusion:
- AlphaCorp is a CFC (Alex owns 100%, a US person with ≥10% ownership).
- GILTI = net CFC tested income − NDTIR. AlphaCorp has minimal tangible assets (QBAI ≈ $0). GILTI ≈ $200,000.
- Alex does not make the §962 election. GILTI taxed at 37% marginal rate.
- US federal GILTI tax: $200,000 × 37% = $74,000.
- No deemed-paid credit available (AlphaCorp paid $0 in US corporate tax).
Spain side — Art. 91 LIRPF CFC imputation:
- Condition 1: Alex holds 100% of AlphaCorp — met.
- Condition 2: AlphaCorp’s effective rate = 0% (credit carryforwards wiped tax). 0% < 18.75% — met.
- Condition 3: income is dividends and interest — qualifying passive income — met.
- Condition 4: 100% of income is passive — exceeds the 15% threshold under Art. 91.4 LIRPF — met.
- All four conditions met. Spain imputes $200,000 to Alex’s IRPF base.
- Alex’s IRPF marginal rate on income above €300,000: 47% (general base rate + savings base nuances — passive income goes to base del ahorro capped at 28% under Art. 66 LIRPF for portfolio income at current rates, but CFC imputation under Art. 91.10 LIRPF is added to the base general, taxed at progressive rates up to 47%).
- Spain IRPF tax on €200,000 imputed CFC income (≈ $200,000 at par): approximately €94,000 (at 47% marginal — simplified; actual depends on full income profile).
Combined exposure without credit relief: $74,000 (US) + €94,000 (Spain) on the same $200,000 of underlying corporate income — an aggregate effective rate exceeding 80% at current USD/EUR parity. This is the double-exposure trap.
6. Foreign Tax Credit coordination: baskets, Treaty, and the limits of relief
US side — GILTI basket. Since the TCJA, GILTI has its own separate foreign tax credit limitation basket under IRC §904(d)(1)(A). Foreign taxes allocated to the GILTI basket cannot offset tax on other income baskets (general limitation, passive, etc.) and vice versa. The deemed-paid credit under §960(d) is limited to 80% of the foreign taxes paid by the CFC that are allocable to GILTI tested income. For a US individual making the §962 election, the credit reduces the effective GILTI rate but rarely eliminates it.
Spain side — credit for US tax under Art. 80 LIRPF and the Treaty. Art. 80 LIRPF provides a general credit for foreign taxes paid on income included in the Spanish tax base, up to the Spanish tax liability on that income. Art. 23 of the US–Spain Convention for the Avoidance of Double Taxation (BOE-A-1991-5325, in force since 1990) provides a credit mechanism: Spain credits the US tax paid on income that is taxable in both countries.
The coordination problem. The credit on the Spain side requires that the tax was actually paid to the US Treasury. A §962 election creates a corporate-equivalent tax at the individual level — it is paid to the IRS — but the computation and attribution rules are complex, and Spanish tax advisors unfamiliar with §962 mechanics sometimes fail to claim it correctly. Moreover, if the US tax arises from a §962 election and is subsequently partially recovered by the §962(d) second-level tax credit on distribution, the net US tax paid (the creditable amount) changes year-by-year.
The GILTI high-tax exclusion as an upstream solution. Treas. Reg. §1.951A-2(c)(7) allows a GILTI high-tax exclusion (GILTI HTE): if the effective foreign tax rate on the CFC’s tested income exceeds 18.9% (90% of 21%), the income may be excluded from GILTI entirely. A Delaware C-Corp paying a blended US effective rate above 18.9% after all deductions and credits can potentially use the GILTI HTE to remove the US GILTI inclusion — and if GILTI is excluded on the US side, the imputed income on the Spain side may also be reduced (because the low-tax condition under Art. 91 LIRPF may no longer be met). This is the cleanest coordination outcome — but it requires genuine tax payment at the entity level.
7. When the §962 election helps — and when it doesn’t — from Spain’s perspective
The §962 election is exclusively a US-side tool. It reduces the US effective rate on GILTI, unlocks a deemed-paid credit, and reduces the net US tax actually paid. From Spain’s perspective:
It helps — indirectly. By creating a larger documented US tax payment (via §960(d) deemed-paid credit mechanics), the §962 election can increase the creditable amount available against Spain’s Art. 91 LIRPF charge under Art. 80 LIRPF and the Treaty. The more US tax that is demonstrably paid (not merely accrued), the larger the Art. 80 credit on the Spanish return. Net: the §962 election reduces the combined effective rate.
It does not eliminate the Spain charge. Art. 91 LIRPF is triggered by Spanish domestic conditions (control, low tax, passive income ratio). A US individual making the §962 election is still taxed at 21% at the entity level — which, depending on the CFC’s blended rate, may or may not satisfy Spain’s 18.75% low-tax threshold. If the C-Corp’s effective US tax rate (after all credits) is below 18.75%, Spain’s CFC regime still triggers.
The surprising case where §962 is counterproductive. If the §962 election causes the US effective rate to appear low (because the §250 deduction reduces the tax base, not raises the rate), and the deemed-paid credit is then limited by the GILTI basket, the net US tax documented could be lower than without the election — potentially reducing the Art. 80 LIRPF credit on the Spanish side. This is a model-before-you-elect situation.
8. Case study: “Liam” — US founder, Spain resident, Delaware C-Corp, $500k passive income
Profile. Liam is a 38-year-old US citizen. He founded a Delaware C-Corp in 2018 (call it “NovaCorp”). He owns 100% of the shares. NovaCorp holds a portfolio of private credit instruments generating $500,000 of interest income per year. NovaCorp has minimal tangible assets — QBAI ≈ $0. Liam relocated to Barcelona in January 2024 and applied for the Beckham regime. His application was approved. He will be under Art. 93 LIRPF (Beckham) for tax years 2024–2029, reverting to the general LIRPF regime from 1 January 2030.
Years 1–6: Beckham window (2024–2029)
US side. Liam is a US shareholder of a CFC. GILTI = $500,000 (near-zero QBAI). Without the §962 election, GILTI is taxed at 37%: US GILTI tax = $185,000. With the §962 election: GILTI inclusion after §250 deduction (50%) = $250,000, taxed at 21% = $52,500. Liam files Form 8993 and attaches the §962 election statement. NovaCorp has historically paid $0 in US corporate tax (R&D credits consumed). No deemed-paid credit available. Net US GILTI tax with §962 election: $52,500. Savings vs. no-election: $132,500 per year.
Spain side. Liam is under the Beckham regime (Art. 93 LIRPF). His Spanish tax base is limited to Spanish-source income. Art. 91 LIRPF CFC imputation is income attributed from NovaCorp, a foreign entity — not Spanish-source income. Art. 91 LIRPF does not apply during the Beckham window. Spain charges $0 on the NovaCorp income during years 1–6.
Combined: years 1–6. Effective combined rate: $52,500 US tax / $500,000 income = 10.5%. Favorable.
Year 7 (2030): reversion to general LIRPF
US side. §962 election continues. US GILTI tax: $52,500 (same as above).
Spain side. Liam is now under the general LIRPF regime. Art. 91 LIRPF analysis:
- Condition 1: 100% ownership of NovaCorp — met.
- Condition 2: NovaCorp’s effective US rate after §962 election economics: 21% applied to the §962 “corporate” base — but at the entity level, NovaCorp pays $0 (it has consumed all credits). Effective entity-level rate = 0%. 0% < 18.75% — condition 2 met.
- Condition 3: $500,000 of interest income — qualifying passive — met.
- Condition 4: 100% passive — met.
Spain imputes $500,000 to Liam’s IRPF base general (Art. 91.10 LIRPF). At 47% marginal rate (top bracket for residents in Catalonia including regional surcharge): Spain IRPF charge ≈ $235,000.
Credit relief. Liam can claim a credit under Art. 80 LIRPF for US taxes paid: $52,500 credited against $235,000. Net Spain tax after credit: $182,500.
Combined year 7: $52,500 (US, §962) + $182,500 (Spain, net of credit) = $235,000 on $500,000 income. Effective combined rate: 47%. The Beckham cliff is steep.
Lesson: The six-year Beckham window gives Liam breathing room to restructure NovaCorp before year 7. Options include: (a) converting NovaCorp to a Delaware LLC ( disregarded entity for US purposes, potentially reclassified as transparent for Spain purposes); (b) distributing retained earnings before reversion under year-6 Beckham treatment; (c) increasing NovaCorp’s QBAI to reduce GILTI inclusion; (d) converting passive income to active trading income to break Art. 91 LIRPF condition 3/4. All four require careful modeling — the LLC conversion has its own transfer tax and US exit charge analysis.
The planning horizon is the six Beckham years. If Liam does nothing before 2030, year 7 is a 47% combined rate event. If he restructures in year 5 or 6, the tax cost of restructuring is borne under Beckham-favorable treatment. The window matters.
Conclusion
GILTI and Spain’s Art. 91 LIRPF are not alternatives. They are cumulative. Every US citizen who holds a CFC-classified entity and becomes a Spanish tax resident needs to model both regimes before making the move — or before the Beckham window closes. The §962 election is a US-side rate optimization tool; it does not cancel the Spanish charge. Foreign Tax Credit coordination under Art. 80 LIRPF and the US–Spain Treaty provides partial relief but rarely full elimination.
The pre-move restructuring window is the most valuable and most underused planning opportunity available to US founders and HNW investors relocating to Spain. Once you are a Spanish tax resident and the entity has accumulated earnings, the options narrow and the costs of restructuring rise.
If you own a US entity, are considering or have completed a Spanish relocation, and have not modeled your Art. 91 LIRPF exposure, the analysis should happen now — not at your next filing deadline.
