How to Combine Onshore and Offshore Entities

Building a smart mix of onshore and offshore entities can sharpen your tax efficiency, protect intellectual property, streamline operations across markets, and make your company more valuable at exit. Done poorly, it triggers audits, banking headaches, and restructuring costs that dwarf any savings. I’ve helped founders, CFOs, and investors design cross-border structures for years, and the winners all follow the same playbook: keep it commercially sound, document everything, and match profits with real substance.

What “Combining Onshore and Offshore” Actually Means

You’re blending entities in higher-tax countries (onshore) with those in lower-tax or strategically located jurisdictions (often called offshore, though many are well-regulated and onshore in practice). The goal isn’t to hide profits. It’s to:

Allocate functions to the best location for that activity.

Prevent double taxation while respecting local rules.

Support growth, fundraising, and an eventual exit with clean, auditable structures.

A simple example: a US parent holds IP in Ireland, operates a regional sales hub in Singapore, and runs a procurement company in the UAE. Each entity has real people, real contracts, and arm’s-length pricing that matches its role.

Core Principles Before You Pick a Jurisdiction

Align tax with value creation. Profit should follow where decisions, risks, and people live. Paper shells are audit magnets.

Substance over form. Office lease, payroll, directors, and board minutes matter as much as your org chart.

Transparency by design. Assume tax authorities, banks, and buyers will review intercompany agreements and TP files.

Keep it as simple as possible. Every extra entity adds annual filings, audits, and risk. If it doesn’t clearly earn its keep, don’t form it.

Plan for exit early. Buyers pay less for messy structures. Clean allocations and IP ownership cut diligence time and earn trust.

Choosing Jurisdictions: What Actually Matters

Key evaluation criteria

Corporate tax rate and incentives: Not just the headline rate—look at patent boxes, R&D credits, and real-life eligibility.

Treaty network: Treaties reduce withholding taxes on cross-border dividends, interest, and royalties. Thin treaty networks can wreck your cash flow.

Substance and CFC rules: Economic Substance Rules (ESR), Controlled Foreign Corporation (CFC) rules, and anti-hybrid regulations can blunt tax benefits if you don’t meet tests.

Banking and payments: Can you open accounts and accept card payments? Time-to-bank ranges from 4–12 weeks in many places.

Legal predictability: Familiar courts, robust corporate law, and investor acceptance matter for financing and M&A.

Compliance friction: Audit thresholds, VAT/GST registration, statutory accounts, and director residency requirements add recurring costs.

Common jurisdictions and typical roles

United States: Parent for US-focused companies; strong investor familiarity; complex international tax (GILTI, Subpart F), but deep capital markets.

United Kingdom: Holding and operating company with solid treaty network, R&D incentives, and deep talent markets.

Ireland: Popular for IP holding and EMEA HQ; 12.5% trading rate; strong substance expectations; excellent treaty network.

Netherlands: Distribution hubs and holdings; good treaties, but anti-abuse rules tightened in recent years.

Singapore: Regional HQ for APAC; competitive 17% rate with incentives; strong banking; credible substance environment.

UAE: Regional operating and distribution hubs; 9% corporate tax for most businesses; favorable logistics and growing treaties; ESR applies.

Hong Kong: Territorial tax system for profits sourced outside HK; strong banking and trade ecosystem; substance and TP enforcement increased.

Luxembourg, Switzerland: Institutional-friendly for holdings/finance; case-by-case due to substance and Pillar Two considerations.

BVI/Cayman/Jersey: Fund, SPV, or IP holding uses with tight investor/legal frameworks; need robust substance to avoid reputational and tax risk.

No single jurisdiction “wins” across the board. Match your map to where your customers, leadership, engineers, and capital live.

Common Structure Patterns That Actually Work

1) Parent-HoldCo + Regional OpCos

Parent in home country (e.g., US/UK).

EMEA HoldCo in Ireland or Netherlands; APAC HoldCo in Singapore.

Local operating subsidiaries under each HoldCo.

Why it works: Clean legal separation by region, easier divestitures, treaty access for dividends, and straightforward governance.

2) IP Company + Operating Companies

IPCo in Ireland or UK (or in some cases, Singapore).

Operating companies in customer markets (e.g., Germany, US, Australia) licensed to use IP.

How profits flow: Ops pay royalties to IPCo under arm’s-length agreements. IPCo must have R&D leadership and control over development and exploitation decisions.

3) Limited-Risk Distributor (LRD) or Commissionaire for Sales

Regional entity acts as LRD: buys from parent and resells locally, earning a stable margin (often 2–5% operating margin).

Commissionaire: sells in its name but risk and title stay with principal; earns commission (often 3–8%).

This limits volatility and supports predictable, defendable TP.

4) Shared Services Center (SSC)

Centralize back-office functions: finance, HR, procurement, support.

Cost-plus model (typical markup 5–12% depending on function and comparables).

This allocates routine profits to the SSC while higher-margin returns stay with entrepreneurial risk-takers.

5) Captive Finance or Treasury

Intra-group lending, cash pooling, and FX executed from a treasury company in a stable jurisdiction.

Must meet thin-cap rules, interest limitation (e.g., EBITDA-based), and anti-hybrid rules. Arm’s-length interest is key.

Example architectures by business model

SaaS: IP and product in Ireland/UK; sales hubs in US, EU, Singapore; SSC in a cost-effective location; clear intercompany license.

E-commerce: Procurement/fulfillment in UAE/HK; LRDs in destination markets; VAT/OSS compliance; returns handling locally.

Consulting/Agencies: Principal entity where leadership and sales sit; staffing subsidiaries or EORs in delivery countries; avoid hidden PEs via secondments and contracts.

Manufacturing: IPCo for intangible returns; principal manufacturing with contract manufacturers under clear pricing; regional distributors with modest margins.

Tax Mechanics Without the Jargon Trap

Permanent Establishment (PE)

If you’re “doing business” in a country (offices, dependent agents closing deals, warehouses), you may have a PE and owe local tax. The line keeps moving. Sales teams habitually negotiating and concluding contracts in-country will likely create a PE. Use LRDs or commissionaires with well-defined authority limits, and train teams to follow them.

Transfer Pricing (TP)

Set prices between related companies as if they were independent. For most groups:

Services: Cost-plus with a supportable markup (5–12% is common; IT/engineering services can justify higher).

Distribution: Target an arm’s-length operating margin (2–5% for limited-risk distributors; more for full-risk distributors).

IP licenses: Percentage of revenue or profit split; ranges vary widely by sector and IP uniqueness.

Financing: Interest rate aligned with credit rating, collateral, and currency; document comparables.

Document in a master file and local files, and refresh annually. Many audits begin with “show me your TP policy.”

Withholding tax (WHT) and treaties

Dividends, interest, and royalties can face 5–30% WHT outbound. Mitigate with:

Treaty planning: Place holdings in treaty-friendly jurisdictions and satisfy Limitation on Benefits (LOB) clauses.

Domestic exemptions: EU Parent-Subsidiary Directive, participation exemptions, and domestic WHT exemptions where available.

Substance: Shell HoldCos get treaty benefits denied.

CFC rules and US-specific traps

CFC regimes (US, UK, many EU countries) attribute low-taxed foreign income back to the parent.

US GILTI: Imposes a minimum tax on certain foreign earnings of US shareholders; blending and high-tax exclusions may help.

Subpart F and PFIC rules create additional complications. Model US shareholders’ impacts early.

OECD BEPS and Pillar Two (Global Minimum Tax)

Groups with consolidated revenue €750m+ face a 15% minimum effective tax under Pillar Two (GloBE). Even below the threshold, many countries adopted similar thinking in audits. Substance-based carve-outs and safe harbors help, but modeling is essential if you’re scaling.

Indirect taxes: VAT/GST and DSTs

VAT/GST registration triggers can be low or even zero for digital services. Use OSS/IOSS in the EU to simplify.

Market-specific Digital Services Taxes (DSTs) target certain online revenues. Watch nexus thresholds and compliance filings.

For e-commerce, duties and import VAT planning often saves more than corporate tax tweaks. Optimize HS codes and Incoterms.

Customs and trade

Preferential tariffs via FTAs, bonded warehouses, and free zones can materially reduce cost of goods sold.

Keep proper origin documentation; buyers will ask during diligence.

Substance and Operational Reality

What “substance” looks like

Local directors and board meetings in the jurisdiction; decisions recorded and consistent with authority.

Office space with staff performing the entity’s core functions.

Payroll, local vendors, and everyday operational footprints.

Decision logs, travel records, and calendars demonstrating where key decisions were made.

I’ve seen audits hinge on meeting calendars and Slack logs. If major decisions are made in London but your board minutes say Dubai, expect questions.

Banking and payments

Multi-currency accounts and payment processors that support your markets are critical.

Banking KYC delays kill timelines. Budget 6–12 weeks for new accounts and prepare a tight package: org chart, UBOs, source of funds, business plan, sample contracts.

Consider a global transaction bank or payment service provider for smoother multi-entity collections and settlements.

People and HR

Employer of Record (EOR) is useful for a quick start, but long-term reliance can create PE and misclassification risks.

Secondments need intercompany agreements and charge-backs; manage shadow payroll for outbound assignees.

Immigration planning: visas tied to the entity support substance and reduce PE risk created by long-term visitors.

Data and IP control

GDPR and other data-residency rules affect where you can host and process data.

Standard Contractual Clauses (SCCs) for EU data transfers and data processing agreements between group entities are non-negotiable.

Keep IP ownership aligned with where development leadership and risk control actually sit. Cost-sharing agreements for R&D can be powerful when done right.

Profit Repatriation and Funding Flows

Funding the group

Equity for long-term capital; intercompany loans for flexibility. Watch thin-cap and interest deduction limitations (often ~30% EBITDA).

Avoid hybrid mismatch arrangements that trigger denials of deductions or double inclusion.

Cash pooling or netting centers can cut FX and working capital costs—document treasury policies.

Moving profits

Dividends: Simple but may face WHT; use treaties/participation exemptions to reduce or eliminate.

Royalties: Allow IP returns to flow to IPCo; watch local caps and WHT.

Interest: Lends flexibility; ensure arm’s-length and monitor interest limitation rules.

Services/management fees: Charge for real services at cost-plus; avoid “head office fees” without substance.

A blended approach usually works best. For example, LRD margins in market, royalties to IPCo, and cost-plus for shared services—each with clear benchmarking.

Documentation and Compliance Calendar

Must-have documents

Intercompany agreements: Licenses, services, distribution, financing, cost-sharing.

Transfer pricing policy: Master file, local files, benchmarking studies; refresh annually.

Board minutes, decision logs, director appointment letters, and meeting schedules.

Economic substance filings: Annual ESR in jurisdictions like UAE, Cayman, Jersey.

UBO/PSC registers and filings; CRS/FATCA classification and reporting.

VAT/GST registrations and evidence of cross-border treatment; e-invoicing where required.

Reporting frameworks to watch

Country-by-Country (CbC) reporting: Generally for groups over €750m revenue.

DAC6/MDR: Reportable cross-border arrangements in the EU if certain hallmarks are met.

Pillar Two/GloBE: For large groups; safe harbors and transitional rules are evolving.

Local payroll and social security filings; shadow payroll for secondees.

Build a calendar across entities with filing owners, due dates, and a single source of truth for documents. Missed filings often surface in M&A diligence.

Step-by-Step Implementation Plan

Phase 1: Discovery and design (2–4 weeks)

Map business model: where customers, teams, IP, and leadership sit today and in 24–36 months.

Identify regulatory triggers: licenses, VAT/DST, payroll, data residency.

Build a strawman structure with 2–3 options; model tax and cash impacts.

Phase 2: Jurisdiction selection and modeling (2–6 weeks)

Compare 3–4 candidate jurisdictions per function using the criteria above.

Run tax sensitivity: WHT with/without treaties, CFC impact, Pillar Two exposure, VAT flows.

Choose final architecture with advisors and your board.

Phase 3: Setup (6–12 weeks, sometimes longer for banking)

Incorporate entities and appoint directors; draft constitutional documents.

Open bank accounts and payment processor relationships; prepare enhanced KYC pack.

Phase 4: Intercompany framework (4–8 weeks, overlaps)

Draft and sign intercompany agreements.

Prepare TP master file and initial local files; set markups/margins in ERP.

Implement SSR and SLA metrics for shared services; create invoice templates.

Phase 5: Operational rollout (4–12 weeks)

Hire key personnel; sign lease; establish IT stack and controls.

Train sales and finance teams on who can sign contracts, pricing authorities, and invoice flows.

Update terms of service and customer contracts to reference the right contracting entity.

Phase 6: Stabilize and review (ongoing)

Monthly: Reconcile intercompany balances; true-up TP margins.

Quarterly: Review substance and PE risks; adjust staffing and board cadence.

Annually: Refresh TP studies; file ESR; revisit structure vs. strategy.

Budget and timeline realities

Initial setup for a three-entity structure (HoldCo, IPCo, OpCo): $50k–$150k including legal, tax, TP, and banking.

Ongoing annual costs per entity: $10k–$50k for accounting, audit, TP updates, and compliance.

Banking timelines are the biggest wildcard. Start applications early and maintain strong reference letters.

Practical Case Studies

Case 1: US SaaS expanding to EMEA and APAC

Situation: US C-Corp with 40% revenue overseas, engineers in the US and Poland, outbound enterprise sales ramping in Germany and Singapore.

Structure:

US parent owns IP initially.

Irish IP and EMEA operating company; Singapore sales hub and SSC.

Poland dev subsidiary services IPCo on cost-plus 12%.

Mechanics:

EMEA sales via Irish contracting entity; local German LRD earns 3% margin.

IP assignment and cost-sharing from US to Ireland as leadership shifts; royalty back to IPCo.

Singapore sells to APAC customers; SSC charges cost-plus 7% to group entities.

Outcome:

Clean regional P&L, reduced WHT via treaties, and strong banking footprint.

During diligence, buyer appreciated documented IP migration and clear TP files; zero surprises.

Case 2: EU e-commerce with procurement in Asia

Situation: DTC brand with US and EU customers, suppliers in China and Vietnam, returns centers in Germany and the US.

Structure:

Netherlands HoldCo, UAE procurement and logistics entity, EU LRDs for local VAT and returns.

Mechanics:

Procurement entity buys, arranges freight, and sells to LRDs; earns 4% net margin.

LRDs handle local VAT through OSS/IOSS where applicable; returns processed locally.

Outcome:

Reduced import duties through optimized HS codes, better shipping terms, and clarity for marketplace VAT rules.

Case 3: UK consulting firm with global delivery

Situation: UK-based leadership, consultants across India and the Philippines via EOR.

Structure:

UK principal company; India and Philippines subsidiaries replace EOR for key staff.

Clear secondment agreements for UK experts on projects abroad.

Mechanics:

Delivery subsidiaries charge cost-plus 15% (reflecting specialized skills).

Avoided unintended PEs by limiting UK staff authority in client locations and contracting through the UK principal.

Outcome:

Lower delivery cost, fewer PE risks, and cleaner client contracting. Faster collections via local invoicing.

Common Mistakes That Cost Real Money

Brass-plate entities: Mailbox companies with no staff or real decision-making. Banks and tax authorities see through this quickly.

Treaty shopping without substance: Using a HoldCo for WHT savings but failing LOB tests leads to denials and back taxes.

Ignoring PE risk: Salespeople habitually negotiating contracts in-country without a local entity or policies.

Sloppy transfer pricing: No benchmarking, margins all over the place, and no intercompany agreements. Auditors love this.

VAT neglect: Registering late, misapplying place-of-supply rules, or ignoring marketplace facilitator rules.

Over-complication: Too many entities and flows. If your CFO can’t whiteboard it clearly, simplify.

Banking last: Treating bank onboarding as paperwork rather than a critical path item.

IP misalignment: Claiming IP resides where there are no engineers, no product managers, and no decision-making.

EOR forever: Relying on EOR long-term in major markets, then facing PE assessments and employee misclassification.

Poor change management: Contracting entity changes not reflected in customer contracts or invoicing; revenue recognition chaos.

Governance That Stands Up in Audits and Diligence

Board cadence and decision trail: Schedule quarterly in-jurisdiction board meetings; maintain agendas and resolutions tied to actual decisions.

Delegations of authority: Who can approve pricing, sign contracts, and hire. Keep it consistent across legal entities.

Controls over intercompany: Monthly reconciliations, clear invoice timing, and variance analysis on margins.

Risk and compliance dashboard: Track filings, ESR, VAT, payroll, and KYC renewals. Assign owners and backups.

In M&A, diligence teams go straight to intercompany agreements, TP studies, bank letters, and board minutes. Make those your strongest artifacts.

Legal and Regulatory: The Non-Tax Essentials

AML/KYC and UBO transparency: Expect requests from banks and marketplaces for UBO documentation and source-of-funds.

Data privacy: SCCs for EU data transfers; data mapping to support RoPA (records of processing activities) and DPIAs when needed.

Employment and immigration: Local contracts, statutory benefits, and visa policies aligned with actual roles.

Licensing: Payment, lending, brokerage, crypto, healthcare, or marketplace activities can trigger licenses. Solve early.

Insurance: D&O for HoldCos, professional indemnity for services, product liability for e-commerce, cyber insurance for SaaS.

Tools and Partners That Make This Easier

ERP/accounting: A system that supports multi-entity, multi-currency, and intercompany (e.g., NetSuite, Microsoft Dynamics, Xero with add-ons).

TP and benchmarking: Subscription databases for comparables; a documented TP calendar to refresh studies annually.

Global payroll and HRIS: Platforms with entity-aware payroll and EOR options.

Compliance tracking: A shared calendar with task owners; consider GRC tooling if you run a larger group.

Advisors: Use a lead coordinator (often your international tax counsel) who can orchestrate local providers. Cheap incorporators can be expensive when something breaks.

A Practical Checklist

Strategy and design

Clarify where revenue, people, and IP will be in 24–36 months.

Pick jurisdictions using tax, banking, and operational criteria.

Model tax and cash impacts, including WHT and CFC exposure.

Setup

Incorporate entities and appoint resident directors where needed.

Open bank accounts; secure payment processing.

Intercompany framework

Draft and sign IP licenses, services, distribution, and loan agreements.

Establish TP policy with benchmarks; load margins into ERP.

Implement billing cadence for intercompany charges.

Substance

Hire key roles; lease space; run board meetings in jurisdiction.

Maintain decision logs and support for place of effective management.

Compliance

Build a filing calendar: ESR, UBO/PSC, VAT, CbC, DAC6/MDR, payroll.

Prepare master file and local files; update annually.

Align data privacy (SCCs, DPAs) and insurance coverage.

Operations

Train teams on contracting entities and authorities.

Align customer contracts and invoices with the new structure.

Monitor PE risks and adjust policies or entity footprint.

Ongoing

Monthly intercompany reconciliations and TP margin checks.

Quarterly governance reviews and substance check-ins.

Annual structure review against business goals and law changes.

When a Simple Structure Is Best

If you’re sub-$5m revenue with one or two core markets, a parent plus one foreign subsidiary may be all you need. Focus on:

Getting paid and staying compliant with VAT/sales tax.

Avoiding PE risk with clear sales protocols.

Building basic TP documentation even if flows are small.

You can layer in IP or HoldCos later without scaring investors or buyers.

Personal Notes from the Trenches

Banks trump tax. I’ve seen perfect tax plans stall for months because a bank didn’t like the customer profile. Build banking early with robust documentation and references.

Put finance in the room early. Sales-driven designs often forget VAT, resulting in back taxes and margin hits.

Train your people. Most PE problems start with well-meaning sales teams overstepping authority. A one-hour training and a cheat sheet save a lot of money.

Keep a “one-page map” of your structure. Every quarter, review it with your leadership team. If you can’t explain the why for each entity, you probably don’t need it.

Final Thoughts

Combining onshore and offshore entities isn’t about chasing the lowest tax rate. It’s about building a durable, bankable, and saleable operating model that matches how your business actually runs. Choose jurisdictions for specific roles, back them with real substance, and price intercompany transactions as independent parties would. If you document well and keep things straightforward, you’ll gain the flexibility to scale globally without leaving landmines for your auditors—or your future buyer.
