Tax Structure Advisory

Required Inputs

Entity/Group Description: Current corporate structure, entity types, and jurisdictions of incorporation and operation.
Business Objectives: Expansion, restructuring, IPO readiness, M&A, or operational efficiency.
Revenue Geography: Where revenue is generated and where customers are located.
Key Functions & Assets: Where management, IP, employees, and tangible assets reside.
Target Jurisdictions: Countries or states under consideration for new entities or migrations.

Execution Steps

1. Current Structure Assessment

Map the existing group structure and identify pain points:

Dimension	Current State	Issue Identified
Entity types	[C-corp, LLC, etc.]	[Mismatch with objectives?]
Jurisdictions	[List]	[High-rate jurisdictions without offsetting benefits?]
Intercompany flows	[Dividends, royalties, services, interest]	[Withholding tax leakage?]
Functional substance	[Where are people, decisions, assets?]	[Substance gaps?]
Tax attributes	[NOLs, credits, basis]	[At risk of expiration or forfeiture?]
Effective tax rate	[Current blended ETR]	[Above benchmark for industry?]

2. Entity Structure Options Analysis

Evaluate entity type alternatives against the business objectives:

Entity Type	Tax Treatment	Liability Protection	Flexibility	Best Suited For
C-Corporation	Entity-level tax (21% US federal); dividends taxed again to shareholders	Full	IPO-ready; unlimited shareholders	Operating companies, PE-backed, public companies
S-Corporation	Pass-through; single level of tax; limited to US shareholders	Full	Max 100 shareholders; one class of stock	Domestic owner-managed businesses
LLC (partnership-taxed)	Pass-through; allocations flexibility; self-employment tax issues	Full	Highly flexible operating agreement	JVs, real estate, multi-owner businesses
Limited Partnership	Pass-through; limited partners have no SE tax; GP has unlimited liability	Limited partners only	GP/LP structure	Investment funds, family holding structures
Branch / PE	Taxed as extension of foreign parent; no withholding on profit remittance	None (parent liable)	Simple but PE risk	Market entry, construction projects, temporary operations
Subsidiary	Separate legal entity; local tax on profits; withholding on distributions	Full	Independent operations	Permanent market presence, regulatory requirements
Holding Company	Participation exemption on dividends/gains; treaty access; IP/financing hub	Full	Central cash management	Group structuring, dividend routing, IP holding

3. Jurisdiction Comparison Framework

Compare candidate jurisdictions for holding or operating entities:

Factor	Jurisdiction A	Jurisdiction B	Jurisdiction C	Jurisdiction D
Corporate income tax rate	___%	___%	___%	___%
Participation exemption	Yes/No (conditions)
Treaty network breadth	___ treaties
Withholding tax: dividends	___% (treaty rate)
Withholding tax: interest	___%
Withholding tax: royalties	___%
CFC rules applicable?	Yes/No (scope)
Substance requirements	[Description]
Anti-avoidance (GAAR)	[Scope]
IP box / patent box	Yes/No (rate)
Group relief / consolidation	Yes/No
Capital gains tax on share sales	___%
Thin capitalization rules	[D:E ratio or EBITDA %]
Exit tax on migration	Yes/No
Time to incorporate	___ weeks
Ongoing compliance cost	$___K/year

Key holding company jurisdictions to evaluate (when applicable):

Netherlands: Participation exemption, wide treaty network, innovation box (9%), fiscal unity.
Luxembourg: Participation exemption, IP regime, SOPARFI structure, wide treaty network.
Ireland: 12.5% rate, IP regime (6.25%), EU membership, knowledge development box.
Singapore: Territorial system, 17% rate, extensive ASEAN treaties, no capital gains tax.
UAE: 0% corporate tax (qualified free zone entities), no withholding taxes, limited treaty network expanding.
Switzerland: Cantonal rates vary (12-14% effective), IP box, principal company regimes.
Hong Kong: Territorial (8.25%/16.5%), no withholding on dividends, no CFC rules.
UK: 25% rate but no withholding on dividends, wide treaty network, patent box (10%).

4. Operating Structure Design

Define the functional role of each entity in the group:

Entity Role	Function	Key Tax Consideration
IP Holding Company	Owns and licenses IP to operating entities	Royalty withholding rates; IP box eligibility; DEMPE substance
Financing Company	Provides intercompany loans; manages group treasury	Thin cap rules; interest deduction limits; arm's length interest rates
Management / Principal Company	Employs key decision-makers; bears entrepreneurial risk	Must have genuine substance; risk of PE for other entities
Operating Entities	Conduct local business operations	Local tax compliance; TP on intercompany charges
Regional Holding Company	Holds shares in operating subs in a region; dividend conduit	Participation exemption; treaty access for withholding reduction

For each entity, document the substance requirements: number of qualified employees, local board members, local decision-making, physical office, and operating expenditure.

5. Dividend Repatriation Planning

Design the cash repatriation path from operating entities to the ultimate parent:

Flow	From	To	Gross Amount	WHT Rate	Treaty Applied	Net After WHT	Participation Exemption?
Operating dividend	OpCo [Country]	HoldCo [Country]	$___M	___%	[Treaty]	$___M	Yes/No
Intermediate dividend	HoldCo [Country]	Parent [Country]	$___M	___%	[Treaty]	$___M	Yes/No
Total repatriation cost							___% leakage

Treaty shopping analysis: Verify each entity in the dividend chain satisfies:

Limitation on Benefits (LOB) provisions in US treaties
EU Parent-Subsidiary Directive conditions (for EU entities)
Principal Purpose Test (PPT) under MLI Article 7
Local beneficial ownership requirements

6. Effective Tax Rate (ETR) Modeling

Calculate the blended group ETR under each structural scenario:

ETR = Total Group Tax / Total Group Pre-Tax Income

Where Total Group Tax =
  Sum for each entity of:
    (Local taxable income x Local statutory rate)
  + Withholding taxes on intercompany flows
  - Foreign tax credits utilized
  - Tax incentives / holidays applied
  + CFC inclusions at parent level (if any)

Scenario	Structure Description	Estimated Group ETR	Annual Tax Savings vs. Current	NPV of Savings (10-year)
Current	[As-is structure]	___%	Baseline	Baseline
Option A	[Description]	___%	$___M	$___M
Option B	[Description]	___%	$___M	$___M
Option C	[Description]	___%	$___M	$___M

7. Anti-Avoidance Risk Assessment

Evaluate each structural recommendation against anti-avoidance frameworks:

Risk Category	Description	Likelihood	Impact	Mitigation
BEPS alignment	Does the structure align with OECD BEPS Actions 2-6?	Low/Med/High	[Tax adjustment + penalties]	[Ensure substance matches profit allocation]
GAAR exposure	Could any jurisdiction invoke General Anti-Avoidance Rules?	Low/Med/High	[Structure unwound; tax reassessed]	[Demonstrate commercial rationale beyond tax]
Substance over form	Would any entity be treated as lacking economic substance?	Low/Med/High	[Look-through; benefits denied]	[Maintain minimum substance in each entity]
Economic substance laws	Do entities meet local economic substance requirements (Cayman, BVI, Channel Islands, UAE)?	Low/Med/High	[Penalties, strike-off]	[Substance plan per entity]
CFC rules	Will parent jurisdiction tax passive income of low-tax subsidiaries?	Low/Med/High	[Current inclusion at parent rate]	[Active business exemption; high-tax exclusion]
Permanent establishment	Could activities in a jurisdiction create an unintended PE?	Low/Med/High	[Unexpected local tax filing + liability]	[Limit authority of local agents; avoid fixed place of business]
Transfer pricing challenge	Are intercompany transactions priced at arm's length?	Low/Med/High	[Adjustment + double taxation]	[Robust TP documentation; benchmark studies]

8. Permanent Establishment Risk Analysis

For each jurisdiction where the group has activities but no registered entity:

Factor	Jurisdiction A	Jurisdiction B
Fixed place of business?	Yes/No — describe
Employees or dependent agents?	___ people; authority to conclude contracts?
Duration of activities	___ months
Digital PE risk (under local rules)	Yes/No
Construction PE threshold	___ months (treaty)
Services PE threshold	___ days in any 12-month period
PE risk level	Low/Med/High
Recommended action	[Register / Limit activities / Monitor]

9. Tax-Efficient M&A Structuring

Deal Structure	Tax Implications	Best Suited For
Asset purchase	Buyer gets basis step-up; seller faces double tax (entity + shareholder) if C-corp	Buyer-favorable; cherry-pick assets; step-up benefit outweighs premium
Stock purchase	No basis step-up (unless 338(h)(10) election); seller gets capital gains treatment	Seller-favorable; simpler; contracts/licenses transfer automatically
338(h)(10) election	Treated as asset purchase for tax, stock purchase for legal; buyer gets step-up	Compromise when buying S-corp or consolidated subsidiary
Tax-free reorganization (A/B/C/D)	Deferral of gain for both parties; continuity of interest and business enterprise required	Strategic mergers where both parties want deferral
Section 351 contribution	Tax-free contribution of assets to controlled corporation	New entity formation; restructuring
Spin-off (Section 355)	Tax-free distribution of subsidiary stock to parent shareholders	Divestiture; unlocking value; regulatory requirements
Cross-border merger	Inversion rules (Section 7874); check-the-box planning; withholding on deemed distributions	International combinations

For each transaction, evaluate:

Step-up benefit (NPV of additional depreciation/amortization deductions)
Transaction tax cost (gain recognized, transfer taxes, stamp duties)
Net benefit = Step-up benefit minus Transaction tax cost

10. Group Financing Structure

Design intercompany financing to optimize interest deductions:

Parameter	Rule / Benchmark	Application
Thin capitalization ratio	Varies by jurisdiction (e.g., 1.5:1 to 3:1 D:E)	Ensure intercompany debt does not exceed safe harbor
EBITDA limitation	30% of EBITDA (ATAD / Section 163(j))	Calculate maximum deductible interest per entity
Arm's length interest rate	Based on credit rating of borrower, not group	Benchmark using loan comparables or bond yields
Guarantee fees	0.5%-2.0% of guaranteed amount (typical range)	Charge if parent guarantees subsidiary debt
Cash pooling	Notional or physical; arm's length deposit/borrow rates	Centralize treasury; reduce external borrowing

Interest deduction capacity analysis:

Entity	EBITDA ($M)	30% Limit ($M)	Current Interest ($M)	Excess / Headroom ($M)	Action
Entity A
Entity B
Entity C

11. Tax Attribute Preservation

Assess the impact of restructuring on existing tax attributes:

Attribute	Current Value	At-Risk Event	Preservation Strategy
Net Operating Losses (NOLs)	$___M	Ownership change (Section 382 limitation)	Monitor ownership shifts; 382 limitation = FMV x long-term AFR
Foreign tax credits	$___M	Basket changes; expiration	Accelerate utilization before restructuring
R&D credits	$___M	Change in business; ownership change	Maintain qualified research activities
Basis step-up	$___M	Entity conversion; liquidation	Plan timing of conversions to maximize benefit
Capital loss carryforwards	$___M	Expiration (5 years for corporations)	Generate capital gains to absorb

Section 382 limitation calculation:

Annual limitation = FMV of loss corporation x Long-term tax-exempt AFR
Example: $100M FMV x 4.5% AFR = $4.5M annual NOL usage limit

12. Implementation Roadmap

Phase	Timeline	Actions	Key Risks	Dependencies
1. Design	Weeks 1-4	Finalize target structure; obtain tax opinions; draft intercompany agreements	Advisor alignment	Board approval
2. Entity Formation	Weeks 5-8	Incorporate new entities; obtain tax IDs; open bank accounts; appoint directors	Incorporation delays	Local counsel in each jurisdiction
3. Asset/IP Migration	Weeks 9-16	Transfer assets at arm's length value; execute IP assignments; file transfer pricing documentation	Exit taxes; valuation disputes	Valuation reports; TP benchmarking
4. Operational Transition	Weeks 13-20	Migrate employees; update contracts; redirect revenue flows; implement new intercompany agreements	Business disruption; customer confusion	HR, legal, commercial teams
5. Compliance Setup	Weeks 17-24	Register for local taxes; set up payroll; implement TP monitoring; file initial returns	Filing deadlines	Local accountants
6. Post-Implementation Review	Months 6-12	Audit intercompany flows; verify substance; confirm ETR savings; adjust as needed	Regulatory changes	Internal tax team

Migration tax considerations:

Exit taxes on asset transfers (unrealized gain taxed at departure)
Transfer pricing on IP and goodwill migration
Stamp duties and transfer taxes on real property
Employee tax and social security implications
Withholding on deemed distributions during restructuring
Anti-abuse rules on post-restructuring transactions (e.g., 2-year holding periods)
