IP Patent Box Matrix

IP / Patent Box Regimes Matrix v0.1

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

• 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%) ([T1])
• Qualifying expenditure — R&D expenditure incurred by the taxpayer directly, plus payments to unrelated third parties for R&D ([T1])
• Overall expenditure — qualifying expenditure + acquisition costs of the IP + related-party R&D outsourcing ([T1])
• The 30% uplift (uplift expenditure) — credit for IP improvement value beyond pure R&D spend ([T1])

2.2 Qualifying IP (under MNA)

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 Pre-MNA regimes that included them have been grandfathered or repealed.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

2.3 Tracking obligation

• IP tracking obligation — 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. ([T1])

2.4 Grandfathering

• Grandfathering of pre-MNA regimes — 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. ([T1])

3.3 Notable absences

Notable absences from patent box regimes

Country	Note
United States	No patent box. FDII (Foreign-Derived Intangible Income) deduction effectively reduces the rate on certain foreign-derived intangible income to ~13.125% (post-2018 deduction; under OBBBA P.L. 119-21 effective rate adjusted). FDII is NOT MNA-compliant per OECD review but remains in US law.
Germany	No patent box. Continues to oppose patent box regimes as harmful tax competition.
Brazil	No formal patent box; some sector-specific innovation incentives.
Russia — Skolkovo and IT incentive	Reduced rates for certain IT and R&D categories, broader than a classic patent box.

Section 4 — Computation walk-through

Step 1 — Identify qualifying IP

• Steps to 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

• 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 — common methods — 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 ([T1])

Step 3 — Compute nexus ratio per IP / family

• Nexus ratio computation — 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 formula — 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 and non-qualifying income — 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+)

• Pillar Two top-up tax on patent box income — 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. ([T1])
• 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 ([T2])

Section 5 — Edge cases and special rules

5.1 Acquired IP and the nexus ratio

• Acquired IP treatment in 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

• Related-party R&D outsourcing treatment — 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

• Family tracking election thresholds — 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

• Tax loss year interaction with regime benefit — 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

• Transferred IP rules — 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

• Stacking IP-box and 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 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

• US FDII and 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

• 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).
