Accounting for International Companies — IFRS, US GAAP, Local.

Offshore and mid-shore jurisdictions impose wildly different reporting requirements, and founders often discover compliance gaps only when penalties arrive or banking relationships freeze.

Zero-tax jurisdictions with economic substance rules

• BVI, Cayman Islands, Bermuda: No corporate income tax, but economic substance reporting is mandatory for entities engaged in relevant activities (holding, IP, finance, shipping, headquarters). You must file an annual Economic Substance Notification, demonstrate adequate employees, premises, and decision-making in-jurisdiction, and risk penalties (up to USD 400,000 in the BVI) plus strike-off for non-compliance.
• UAE free zones (RAKICC, JAFZA, ADGM, DIFC): Historically zero-tax, but UAE corporate tax (9% on profits >375,000 AED) applies from 1 June 2023 for most mainland and free-zone entities. Qualifying Free Zone Persons may still enjoy 0% if they meet substance and non-mainland-income conditions. Annual audited accounts, ESR filings, and UBO registers are compulsory.

Mid-shore and territorial regimes

• Hong Kong: Territorial tax (16.5% profits tax on Hong Kong-source income). Audited accounts, profits tax return, business registration renewal. Non-Hong Kong source claims require robust documentation (contracts, IP licences, offshore bank statements).
• Singapore: 17% corporate tax with exemptions for first SGD 200k. Audited accounts (unless small company exemption), ECI estimate, corporate tax return (Form C-S/C), XBRL filing. Transfer pricing documentation required if related-party transactions exceed SGD 15m.

Full-scope jurisdictions

• UK: Corporation tax return (CT600), statutory accounts filed at Companies House, self-assessment for directors if resident. CFC rules apply if UK parent controls offshore entities earning passive income without substance.
• US (Delaware C-corp, LLC): Federal 1120 or 1065, state franchise tax (Delaware: annual report + franchise tax ~USD 400–800), beneficial ownership reporting (FinCEN BOI filing). US persons face GILTI and Subpart F on foreign earnings, plus FATCA Form 8938/FBAR for offshore accounts.
• EU (Ireland, Luxembourg, Cyprus, Malta): Full IFRS or local GAAP accounts, corporate tax return, ATAD compliance (CFC, hybrid mismatch, interest limitation), DAC6 reportable arrangements, UBO register (PSC equivalent), and annual returns. Pillar Two (15% minimum effective tax) applies if consolidated group revenue exceeds €750m.

Iverex maps your group structure to applicable regimes and builds a compliance matrix with deadlines, substance thresholds, and reporting triggers for each entity.

Economic substance requirements (ESR) emerged post-BEPS to prevent treaty shopping and brass-plate structures. If your offshore entity engages in a relevant activity—holding company, intellectual property, financing, shipping, fund management, headquarters, distribution centre, service centre, or lease-finance—you must demonstrate genuine local presence.

Core substance tests

• Directed and managed in the jurisdiction: board meetings, quorum, signatories resident or physically present.
• Core income-generating activities (CIGA) conducted locally: for a holding company, CIGA includes strategic decisions on acquisitions, disposals, and financing; for an IP company, R&D or brand management; for a finance company, loan origination and credit risk.
• Adequate employees, premises, and expenditure: proportionate to activity scale. A USD 50m IP holding with zero employees and a registered-agent address will fail.

Reporting and penalties

• Annual Economic Substance Notification (typically filed within 12 months of year-end).
• If engaged in relevant activity, a detailed Economic Substance Return (employees, premises, CIGA evidence, financial summary).
• Non-compliance triggers automatic exchange of information with tax authorities in the UBO's jurisdiction, fines (BVI: up to USD 400,000), and potential strike-off.
• Cayman Islands: Economic Substance Act penalties up to KYD 100,000 plus automatic reporting to the EU.

Iverex approach

We conduct a substance health check for every offshore entity: map CIGA requirements, assess current footprint (employees, office, board composition), and design a remediation plan if shortfalls exist. For holding companies, we arrange nominee directors with genuine decision-making authority, documented board meetings, and audit trails. For IP or finance entities, we coordinate with local service providers (legal, accounting, admin) to ensure CIGA can be evidenced.

If you are a US person or UK tax resident controlling an offshore entity, substance failures may also trigger CFC or GILTI exposure, compounding tax and compliance risk. Our ESR service integrates with your wider tax structure to ensure substance satisfies both local regulators and home-country anti-avoidance rules.

International Financial Reporting Standards (IFRS) are the global equivalent of GAAP, required or permitted in over 140 jurisdictions. Choosing between IFRS and local GAAP—or preparing both sets of accounts—depends on your domicile, banking relationships, investor expectations, and M&A readiness.

When IFRS is mandatory or advantageous

• EU entities: Listed companies must use IFRS; unlisted may use local GAAP (UK GAAP FRS 102, German HGB, etc.).
• BVI, Cayman, Bermuda, Seychelles: No prescribed standard, but banks and institutional investors demand IFRS for lending and investment committees.
• UAE free zones: Accounts must be audited; IFRS is standard.
• Singapore: Locally incorporated companies use Singapore Financial Reporting Standards (SFRS), which are IFRS-aligned but with nuances (e.g., revenue recognition, leases).
• M&A readiness: Buyers and PE funds expect IFRS or US GAAP for due diligence. Restating three years of local GAAP accounts to IFRS mid-process is expensive and delays closing.

Local GAAP alternatives

• UK FRS 102: Simplified standard for UK SMEs; fewer disclosures than IFRS, no fair-value revaluation unless property.
• US GAAP: Required for US-incorporated entities (Delaware C-corp, Wyoming LLC taxed as C-corp). Key differences vs IFRS: no asset revaluation, different lease and revenue recognition, deferred tax treatment.
• Hong Kong GAAP: HKFRS, virtually identical to IFRS but with small-company exemptions.

Trade-offs

Dual reporting

Some clients maintain statutory accounts in local GAAP (e.g., UK FRS 102 for UK subsidiary, US GAAP for Delaware C-corp) and consolidated IFRS management accounts for the holding company and investors. This dual approach minimises compliance burden at operating level while providing IFRS numbers for board, lenders, and exit readiness.

Iverex prepares accounts under IFRS, UK FRS 102, US GAAP, or SFRS, and coordinates with Big Four or mid-tier audit firms worldwide. If you are preparing for a trade sale, we backdate IFRS restatements to provide three-year Quality of Earnings comparability.

Transfer pricing (TP) governs the pricing of goods, services, IP licences, and financing between related entities. Arm's-length pricing is mandatory under OECD TP Guidelines (adopted by 140+ countries) and local legislation, with penalties for non-compliance ranging from adjustments and interest to reputational damage and MAP disputes.

When transfer pricing documentation is required

• Threshold triggers: Vary by jurisdiction. Singapore: related-party transactions >SGD 15m. UK: no de minimis, but HMRC focuses on >£50m. UAE: all related-party transactions, starting 2024 corporate tax.
• Related parties: >25% common ownership or control, including parent-subsidiary, sister companies, and shared UBO.
• Cross-border and domestic: Most regimes require TP for international transactions; some (US, UK, EU post-ATAD) apply TP to domestic intercompany arrangements if one party is loss-making or tax-exempt.

OECD three-tier documentation

1. Master File: Group overview, value chain, key IP, financing, supply chain. Due once consolidated revenue exceeds €750m.
2. Local File: Entity-specific functional analysis, comparability study, method selection (CUP, RPM, CPM, TNMM, profit split), benchmarking database (e.g., Orbis, RoyaltyStat). Required in most jurisdictions for material intercompany transactions.
3. Country-by-Country Report (CbCR): Allocation of income, taxes paid, employees, and assets by jurisdiction. Mandatory for MNE groups with revenue >€750m, filed in ultimate parent jurisdiction and exchanged via OECD CbC MCAA.

Common intercompany arrangements

• Management fees: HoldCo charges OpCo for strategy, governance, compliance. Arm's-length fee typically 3–8% of OpCo revenue or cost-plus 5–15% of costs incurred.
• IP royalty: Parent licences trademarks, software, or patents to subsidiaries. Benchmarked against CUT (comparable uncontrolled transactions) or CPM with DEMPE (development, enhancement, maintenance, protection, exploitation) analysis.
• Intra-group loans: Interest rate must reflect credit risk, currency, tenor. Use LIBOR/SOFR + margin derived from credit rating or comparable debt.
• Cost-sharing: R&D or shared services split by allocation key (headcount, revenue, usage).

US-specific: Section 482 and GILTI interaction

US persons must comply with IRC Section 482 and maintain contemporaneous documentation. Post-TCJA, GILTI (Global Intangible Low-Taxed Income) subjects CFCs' excess returns to US tax at ~10.5% (21% × 50% deduction, after QBAI and FTCs). Aggressive profit shifting to low-tax jurisdictions triggers GILTI inclusion, eroding expected tax savings. TP policy must balance GILTI, royalty withholding, and substance in CFC jurisdictions.

Iverex approach

We design TP policies aligned with your operating model, draft intercompany agreements (management services, IP licence, loan), conduct benchmarking studies using Orbis or BvD, and prepare Local Files for audit defence. For clients nearing €750m consolidated revenue, we build a Master File and CbCR readiness roadmap 12–18 months ahead of first filing. If you face a TP audit or MAP, we coordinate with Big Four TP specialists and coordinate disputes across jurisdictions.

OECD Pillar Two (Global Anti-Base Erosion Model Rules) introduces a 15% global minimum effective tax rate for MNE groups with consolidated revenue ≥€750m. Effective from 2024 in the EU, UK, and many other jurisdictions, Pillar Two fundamentally reshapes international tax planning and compliance.

Key mechanisms

• Income Inclusion Rule (IIR): Ultimate parent jurisdiction (e.g., UK, US, France) levies top-up tax if a subsidiary's effective tax rate (ETR) in another jurisdiction falls below 15%.
• Undertaxed Profits Rule (UTPR): Backstop if no IIR applies; jurisdictions with group entities allocate top-up tax based on employees and assets.
• Qualified Domestic Minimum Top-up Tax (QDMTT): Jurisdictions (e.g., UAE, Singapore) introduce local 15% top-up to retain revenue rather than ceding it to IIR countries.
• GloBE Information Return: Annual filing per jurisdiction, detailing revenues, profits, taxes, employees, assets, and ETR calculation.

Scope and exemptions

• €750m threshold: Consolidated group revenue over four consecutive years. Once in scope, compliance is ongoing.
• Substance-based income exclusion (SBIE): Carve-out for substance (5% of tangible assets + 5% of payroll). Reduces top-up tax for entities with genuine local operations.
• De minimis exclusion: Jurisdictions with group revenue <€10m and profit <€1m excluded from GloBE calculation.

Impact on common structures

• UK parent with UAE subsidiary: If UAE entity pays 0% (pre-QDMTT) or <15%, UK IIR imposes top-up tax. UAE QDMTT (announced 2024) at 15% eliminates UK top-up.
• US parent with BVI holding company: BVI entity has no income tax. Under US IIR (not yet enacted as of 2024, but expected), GILTI rules interact with Pillar Two. GILTI effective rate ~13.125% post-TCJA (21% × 50% deduction × 1.25 inclusion) is below 15%, triggering top-up unless SBIE or other adjustments apply.
• Luxembourg IP company licensing to group: If Luxembourg IP ETR <15% (due to IP regime, notional interest deduction, or intra-group financing), parent jurisdiction's IIR captures top-up.

Compliance and planning

• ETR calculation: Aggregate covered taxes divided by GloBE income, per jurisdiction. Deferred tax adjustments, timing differences, and attribution rules are complex.
• Safe harbours: Transitional CbCR safe harbour (2024–2026), UTPR safe harbour, routine profit exclusion.
• Restructuring: Consolidating low-tax entities, increasing substance (employees, tangible assets) to maximise SBIE, re-domiciling IP to 15%+ jurisdictions, or accepting top-up tax and simplifying structure.

Iverex Pillar Two readiness

We perform a Pillar Two impact assessment for groups approaching or exceeding €750m: model ETR by jurisdiction, quantify top-up tax liability, evaluate SBIE, and simulate restructuring scenarios (relocating IP, hiring employees, unwinding conduit entities). For clients in scope, we coordinate with Big Four to prepare the GloBE Information Return, maintain safe harbour documentation, and advise on QDMTT elections in jurisdictions like Singapore, UAE, and Hong Kong.

If you are currently sub-€750m but growing through acquisition or organic revenue, we build a Pillar Two-ready structure now—ensuring substance, transfer pricing, and entity placement optimise ETR and minimise future top-up exposure.

Automatic exchange of information (AEOI) regimes—CRS (Common Reporting Standard) and FATCA (Foreign Account Tax Compliance Act)—require financial institutions and, increasingly, offshore corporate service providers to report account holders and beneficial owners to local regulators, who exchange data with tax authorities worldwide. Non-compliance freezes bank accounts, triggers deregistration, and exposes UBOs to penalties in their home jurisdictions.

CRS (OECD Common Reporting Standard)

• Scope: 100+ participating jurisdictions (EU, UK, UAE, BVI, Cayman, Singapore, Hong Kong). Banks, custodians, and investment platforms report financial accounts held by foreign tax residents.
• Reportable information: Account holder name, address, TIN, account balance, interest, dividends, proceeds from sale of assets.
• Passive NFE (Non-Financial Entity) rules: If an offshore company is a passive NFE (investment holding, no active trade), the bank reports controlling persons (UBOs >25%) rather than the entity itself.
• Self-certification: UBOs provide CRS self-certification forms (tax residency, TIN) to banks and service providers. False declarations trigger penalties (e.g., UK: £300 initial + £60/day, plus potential criminal prosecution).

FATCA (US)

• Scope: All non-US financial institutions must report US-person account holders (citizens, green card holders, US tax residents) to the IRS via local tax authority (Model 1 IGA) or directly (Model 2).
• Withholding: Non-compliant institutions face 30% withholding on US-source payments.
• US person definition: Includes US citizens living abroad, accidental Americans, and entities with >10% US ownership (substantial US owners).
• Form 8938 and FBAR: US persons with offshore accounts >USD 50k (FBAR) or financial assets >USD 200k (Form 8938) must file annually with FinCEN and IRS. Penalties for non-compliance: up to 50% of account value.

UBO registers and PSC filings

• UK: Companies House PSC (Persons with Significant Control) register, public. Entities with UK subsidiaries or LLPs must disclose UBOs >25% ownership or control.
• EU: UBO registers per 5AMLD (Fifth Anti-Money Laundering Directive). Centralized national registers, some public, some restricted to authorities and obliged entities.
• BVI, Cayman, Bermuda: Private UBO registers maintained by registered agent, accessible to regulators and exchanged with UK/EU under ESR and AEOI.
• UAE: UBO declaration filed with Ministry of Economy; violations trigger fines up to AED 100,000.

Annual renewals and good standing

• BVI: Annual return, registered agent fee (USD 1,200–2,500), economic substance notification, government fee (~USD 1,100).
• Cayman: Annual return, registered office fee (~USD 2,000–4,000), government fee (based on share capital, ~USD 900–1,200), ESR filing.
• Delaware: Annual franchise tax (minimum USD 400, higher for high par-value or assumed par-value method), annual report.
• UAE free zone: Trade licence renewal (AED 10,000–20,000), ESR filing, audited accounts, UBO declaration.
• Singapore: Annual return (Form C-S/C), ECI estimate, ACRA filing fee (~SGD 60).

Trade-offs and pitfalls

Founders often underestimate AEOI reporting burden when opening offshore accounts. A UAE-resident UK citizen with a BVI holding company controlling a Cayman fund, banking in Singapore, must navigate CRS self-certs in Singapore, ESR in BVI and Cayman, UBO disclosure in UAE, and UK PSC if any UK entities are involved. Missing a single self-cert or late ESR filing can freeze the Singapore account, halting investor distributions.

Iverex compliance calendar

We maintain a master compliance calendar for every entity: annual return deadlines, ESR filings, UBO register updates, CRS/FATCA self-cert renewals, and audit deadlines. Our service includes CRS/FATCA self-certification review, PSC and UBO register updates, annual return filing, registered agent coordination, and audit-ready records for substance and AEOI defence. If you are a US person, we coordinate with US CPAs to ensure offshore accounts, entities, and income are disclosed on FBAR, Form 8938, Form 5471 (CFC), and 1040 Schedule B, avoiding willful or non-willful FBAR penalties (up to USD 100,000 or 50% of account per year).
