What this file is

This file is a content skill that loads on top of cross-border-workflow-base. It implements the global landscape of preferential IP tax regimes that comply with the OECD BEPS Action 5 Modified Nexus Approach (published October 2015, refined through the FHTP peer review process).

Tax year coverage. Current for fiscal year 2025, reflecting:

• OECD FHTP 2024 peer review conclusions
• Hungary patent box regime conformity confirmed
• Cyprus IP box at 80% deduction (effective rate ~2.5%)
• Italian patent box converted in 2021 to an "iper-deduzione" (super-deduction of 110% on R&D costs related to IP — different mechanism from a classic patent box; analysed separately)
• Pillar Two interaction — many IP boxes produce ETRs below 15%, triggering top-up tax exposure (see pillar-two-globe-minimum-tax.md)

The reviewer is the customer of this output. IP box claims are heavily scrutinised in tax audits. Every output must be reviewed by a credentialed practitioner (typically a Big 4 international tax specialist or local tax counsel) before any claim is filed.

Section 1 — Scope statement

This skill covers:

• Modified nexus approach mechanics — qualifying IP, qualifying expenditure, overall expenditure, uplift, embedded income.
• Country regime matrix — rate, scope, mechanism (deduction, exemption, separate rate, super-deduction), grandfathered legacy regimes if any.
• Computation walk-through for the principal regimes.
• Pillar Two interaction — when patent box income triggers GloBE top-up tax.

This skill does NOT cover:

• R&D tax credits — see rd-tax-credits-matrix.md.
• IP amortisation / depreciation — see country corporate tax skills.
• Transfer pricing of IP — see transfer-pricing-workflow-base.md.
• Withholding tax on royalties — see withholding-tax-matrix.md.
• Italian super-deduction (iper-deduzione) beyond a reference — fundamentally different mechanism.

Section 2 — The OECD Modified Nexus Approach (MNA)

2.1 The formula

[T1] Eligible income for the preferential rate:

Eligible IP Income × Nexus Ratio = Income qualifying for the preferential rate

Nexus Ratio = (Qualifying Expenditure × 1.3) ÷ Overall Expenditure
            (capped at 100%)

Where:

• Qualifying expenditure = R&D expenditure incurred by the taxpayer directly, plus payments to unrelated third parties for R&D
• Overall expenditure = qualifying expenditure + acquisition costs of the IP + related-party R&D outsourcing
• The 30% uplift is the "uplift expenditure" — credit for IP improvement value beyond pure R&D spend

2.2 Qualifying IP (under MNA)

[T1] Three categories:

1. Patents — including pending applications, utility models, plant varieties
2. Copyrighted software
3. Other IP that is "functionally equivalent to a patent" — limited to:
   • Other IP rights that are non-obvious, useful, novel, AND certified through a transparent process by a competent government agency
   • The OECD restricts category 3 to companies with annual gross revenue < EUR 50 million AND no more than 7.5% of qualifying IP income is from this category

[T1] Marketing intangibles (trademarks, brand value, customer lists) are NOT qualifying IP under MNA. Pre-MNA regimes that included them have been grandfathered or repealed.

2.3 Tracking obligation

[T1] Taxpayers must track, on an IP-by-IP basis OR product/family-by-product/family basis:

• Qualifying expenditure
• Overall expenditure
• Income from each qualifying IP

Product-family tracking is allowed where IP-by-IP is "exceptionally difficult". The product family must be a coherent class of products with shared underlying IP.

2.4 Grandfathering

[T1] Pre-MNA regimes for IP existing before 30 June 2016 benefit until 30 June 2021 (with limited national extensions). After this date, all regimes must apply MNA.

3.2 Asia-Pacific

3.3 Notable absences

Section 4 — Computation walk-through

Step 1 — Identify qualifying IP

For each potentially qualifying IP asset:

• Confirm category (patent, software, equivalent-to-patent under MNA category 3)
• Confirm legal protection in the jurisdiction(s) relevant under each regime's nationality rules
• Confirm registration / grant date

Step 2 — Identify IP income

[T1] IP income types:

• Royalty income from licensing the IP
• Embedded IP income — income from the sale of products that incorporate the IP, allocated to the IP via a transfer-pricing-style methodology
• Gains on disposal of the IP
• Damages and compensation in respect of the IP

[T1] Allocation of embedded IP income is the hardest practical question. Common methods:

• Comparable royalty rate ÷ sale price
• Residual profit split where the IP is a key driver
• Profit split between IP-related and non-IP-related profit drivers

Step 3 — Compute nexus ratio per IP / family

Numerator   = Qualifying Expenditure × 1.3
Denominator = Qualifying Expenditure + Acquisition Cost + Related-Party R&D Outsourcing
Nexus Ratio = MIN(1, Numerator ÷ Denominator)

Step 4 — Compute qualifying income

Qualifying Income = (Eligible IP Income − Allocable Costs) × Nexus Ratio

Allocable costs include: direct R&D costs (typically expensed during the period), allocated overheads, IP maintenance costs, depreciation of acquired IP.

Step 5 — Apply the regime rate

Tax on Qualifying Income = Qualifying Income × Preferential Rate
Tax on Non-Qualifying Income = Non-Qualifying Income × Standard Rate

Step 6 — Pillar Two interaction (FY 2024+)

[T1] If the entity's jurisdictional ETR (per pillar-two-globe-minimum-tax.md) falls below 15% due to patent box income, the GloBE Top-up Tax applies at the IIR or UTPR level. The patent box benefit may be partially or fully clawed back.

[T2] Mitigations under Pillar Two:

• The QDMTT in the IP-box country captures the top-up tax locally rather than ceding it to a parent jurisdiction
• The Transitional CbCR Safe Harbour may apply through FY 2026 if the simplified ETR test is met (15% for FY 2023/24, 16% for FY 2025, 17% for FY 2026)
• The substance-based income exclusion (SBIE) may reduce the top-up base where the IP-holding entity has payroll and tangible assets locally

Section 5 — Edge cases and special rules

5.1 Acquired IP and the nexus ratio

Acquired IP is in the denominator (overall expenditure) but NOT in the numerator. Heavy IP acquisition drives nexus ratio toward zero. The 30% uplift on qualifying expenditure partially offsets this but cannot exceed 100%.

5.2 Related-party R&D outsourcing

R&D outsourced to related parties is in the denominator only (not the numerator). This is the central mechanism that pushes substance into the IP-holding jurisdiction.

5.3 Family-by-family tracking elections

Each regime sets thresholds for when product-family tracking is permitted (typically: IP-by-IP impossible or impracticable). Tax authorities require advance documentation justifying the family.

5.4 Tax loss interaction

In a loss year for IP-related activities, the unused regime benefit is generally lost. Some regimes (e.g., Belgium Innovation Income Deduction, Netherlands Innovation Box) allow carryforward.

5.5 Transferred IP

When IP is contributed to or sold to the IP-box company:

• The acquisition cost falls into overall expenditure (reducing nexus ratio)
• Pre-MNA acquired IP may benefit from grandfathering only until the regime sunset
• The OECD's "tracking and tracing" requirement applies — historic expenditure must be reconstructed

5.6 Combined IP-box + R&D super-deduction

Some jurisdictions allow stacking (Italy 2021+, Switzerland). Most cap the combined benefit (Switzerland 70%). Verify the country rule.

5.7 Singapore IDI — discretionary status

Singapore's Intellectual Property Development Incentive (IDI) is awarded by the Economic Development Board. The concessionary rate (5/10/15%) is bespoke per company, conditioned on business spend, employment, and IP-creation activities in Singapore.

5.8 US FDII and OECD MNA non-compliance

FDII applies a partial deduction yielding ~13.125% effective rate on Foreign-Derived Intangible Income. The OECD FHTP has rated FDII as not MNA-compliant. The US has not modified FDII. For Pillar Two purposes, FDII tax is included in Adjusted Covered Taxes — but ETR may still fall below 15%.

Section 6 — Output specification

The reviewer brief must include:

1. IP inventory — every patent, software, plant variety, etc., with legal status and country of protection.
2. Income allocation — royalty income identified directly; embedded IP income allocated using a documented methodology.
3. Nexus ratio computation per IP or family, with the numerator/denominator tracking sheet.
4. Qualifying income per regime per year.
5. Tax saving vs the standard rate (sensitivity to nexus ratio and income allocation).
6. Pillar Two impact — ETR analysis post-IP-box benefit; top-up tax exposure if any.
7. Grandfathering schedule for pre-MNA assets.
8. Reviewer questions — open items flagged as [T2] or [T3].

Section 7 — Self-checks

• IP category confirmed within the MNA scope (patent / software / equivalent-to-patent).
• Marketing intangibles excluded from claim.
• Nexus ratio numerator includes only own + unrelated-party R&D.
• Acquired IP and related-party outsourcing in denominator only.
• 30% uplift applied but capped so ratio ≤ 1.
• Embedded IP income allocated using a defensible TP method.
• Family tracking justified if used; IP-by-IP otherwise.
• Pillar Two ETR impact assessed and Top-up Tax modelled.
• Grandfathering of pre-30-June-2016 IP applied within sunset.
• Output flags every [T2]/[T3] item for reviewer judgement.

Section 8 — Prohibitions

• Do not claim a patent box benefit for marketing intangibles (trademarks, brands, customer lists).
• Do not include related-party R&D in qualifying expenditure — only in overall expenditure.
• Do not apply Italian "iper-deduzione" alongside another country's classic patent box on the same expenditure — double benefit is prohibited and likely treaty-abused.
• Do not ignore the Pillar Two top-up tax exposure on patent box benefits — for in-scope MNE groups (>EUR 750m global revenue), the effective benefit may be neutralised.
• Do not advise on relocating IP to an IP-box jurisdiction without considering exit tax in the originating jurisdiction (often a deemed disposal at fair market value).

Section 9 — Disclaimer

This skill and its outputs are provided for informational and computational purposes only and do not constitute tax, legal, or financial advice. Patent box claims face significant audit scrutiny, OECD peer review may move regimes off the approved list, and Pillar Two materially changes the benefit. Every output must be reviewed and signed off by a credentialed international tax practitioner before any claim is filed.
