Why cross-border accounting in the UK is different (HMRC, IFRS vs UK GAAP)
UK cross-border accounting ties every decision to HMRC guidance, UK GAAP or IFRS, and tax treaty outcomes. A strong approach maps where profits are booked, how VAT is treated on EU and non-EU flows, and who has compliance responsibility. That is why UK-led policy, documentation and filing calendars are essential for multinational SMEs.
In practice, you must decide early which standards govern group reporting. Many UK groups report under IFRS for consolidation, then maintain entity ledgers under UK GAAP. You also need positions on permanent establishment risk, withholding tax, and country-by-country obligations, plus controls for multi-currency, intercompany pricing and cross-charge evidence. We bring these threads together into one plan and calendar, then we operate it month by month.
Our work product includes HMRC-ready memos, filing timetables, and reviewer notes your board can sign.

If you are comparing advisers, our roundup of the top international tax consultants in the UK sets out what good cross-border advice looks like.
Our services
Our UK team runs a complete cross-border programme, from tax and VAT to reporting, payroll and treasury. Each service below plugs into one calendar, one data flow and one contact. Need board-level input as well? See our CFO Services.
International tax planning
International tax planning aligns your structure, treaties and cash flows so profits are taxed once and documented. We assess permanent establishment exposure, treaty relief, withholding, hybrid risks and cross-charges, then set a policy that matches your operating model.
You get clear positions on where value is created, how profits are allocated, and how management fees, IP and cost sharing are priced. We also map filing triggers by jurisdiction and build a calendar you can follow.
Deliverables include a tax strategy memo, treaty positions, intercompany cross-charges, and a filing timetable tied to HMRC deadlines. For UK entities, we integrate with Tax Planning for Limited Companies and manage overseas registrations via our Foreign Companies service so group and local compliance stay in sync.
VAT and sales tax compliance
Cross-border VAT hinges on supply chains, incoterms, and place-of-supply rules. We register where needed, operate returns, and document decisions on reverse charge, import VAT and distance sales. For EU trade we handle OSS/IOSS where appropriate, and for non-EU flows we evidence zero-rating or local VAT as required.
Our process starts with a transaction map by country and product or service. We then decide on registrations, invoicing formats, e-invoicing needs, evidence retention, and refund routes for foreign VAT. We also align VAT postings so your general ledger and VAT returns reconcile cleanly.
You receive a VAT matrix, registration plan, filing calendar and monthly controls. For online sellers, see our Ecommerce page. For groups centralising finance in the UK, our Corporate Accountant service connects management accounts to VAT ledgers so audits run faster.
Transfer pricing compliance and documentation
Transfer pricing must be defensible under OECD guidelines and HMRC practice. We set or review intercompany pricing using accepted methods such as CUP, Resale Minus, Cost Plus and TNMM, then maintain the master file and local files that tax authorities expect to see.
We start with a functional analysis across entities, then benchmark margins with independent comparables. Where helpful, we consider advance pricing agreements, year-end true-ups and intercompany agreements that match the policy. We also create audit-ready evidence, including pricing memos, tested party selection and adjustments.
Your outputs include a documented policy, benchmarking pack, local file templates, and a calendar for updates. We route controls through finance so transactions, invoices and journals match the policy each month. For governance across markets, our Risk Management support embeds transfer pricing checks into your close checklist so reviews are repeatable.
Cross-border mergers and acquisitions support
We support buy-side and sell-side deals with tax structuring, financial diligence and post-close integration. Pre-deal, we model structures for treaty outcomes, withholding, interest limitation and loss use. During diligence, we test tax exposures, indirect tax, payroll, and the integrity of management accounts.
Post-close, we align charts of accounts, intercompany routes, and reporting bases so group consolidation works from month one. We also schedule local filings and registrations that follow a change of control. Explore our Due Diligence and M&A pages for related detail.
Currency risk management and hedge accounting
Foreign exchange can erase margin if left unmanaged. We build an FX policy that sets exposures, horizons and instruments such as forwards and options, then connect treasury actions to accounting entries under IFRS 9 or UK GAAP.
You get a forecast-driven exposure view, trade execution rules, documentation for hedge relationships, and journals that reflect effectiveness testing. We coordinate with your banks or platforms, and we reconcile realised and unrealised results in monthly reporting. If you need a reliable basis for hedge sizing, our Business Financial Forecasting service can provide it.
Global payroll and HR compliance
Global payroll requires consistent data, local compliance and clear handoffs. We run UK payroll and coordinate overseas providers so pay, tax and social security are filed correctly. Where inbound or outbound assignees are involved, we manage shadow payroll and A1 or totalisation positions.
We set cutoffs, calendars and controls for gross-to-net, benefits, and equity reporting, then reconcile payroll to your ledgers each month. Employees are paid on time, filings are accepted, and year-end forms are issued accurately. For details on UK processing see Payroll, and for mobile employees see Expats.
Financial reporting and auditing for international groups
Group reporting succeeds when local ledgers, eliminations and currency translation work as one system. We prepare or review consolidations under IFRS, reconcile UK GAAP entities, and produce disclosure-ready notes. Where statutory audits apply, we coordinate auditors and keep close calendars and deliverables aligned.
Our monthly model standardises chart of accounts, intercompany reconciliations, FX translation and cash flow, then rolls forward into quarter and year-end packs. You receive board-ready management accounts and audit-ready files with supporting schedules. For assurance specifics see Financial Statement, and for board support and planning cadence see Virtual CFO Services.
Process: how we onboard and deliver across jurisdictions
A clear process keeps multi-country finance on track. We start with discovery and a document request, then map entities, flows and filings into one calendar. Next, we standardise charts, VAT codes and intercompany routes, then align reporting bases. Finally, we operate monthly controls and refine the plan each quarter.
- Week 1 to 2: discovery, access setup, risk scan.
- Week 3 to 4: policy and calendar sign-off, templates issued.
- Month 2: first close following new controls, filing checks.
- Month 3 onward: steady-state operations with quarterly improvements.
You will have a single UK engagement lead and a ticketed helpdesk for tasks and status. Governance includes board-ready packs and HMRC-ready memos. Ready to confirm scope and timelines? Contact us, or go straight to scheduling and Book a Call.
Tools and platforms we use
Execution relies on proven systems. We work natively in Xero, Sage 50 and Sage 200, and we consolidate in NetSuite or group reporting models we design. For data capture we use Dext and Hubdoc. For VAT determination and filings we integrate Avalara or native returns where appropriate.
Payments and FX routing can run through Wise Business, Revolut Business or TransferMate, tying back to the ledger each day. Our workflow and approvals are managed in a shared portal, with close checklists aligned to your audit needs. For forecasting and board cadence, see Virtual CFO Services.

Comparison: UK GAAP vs IFRS for cross-border filers
UK GAAP and IFRS differ on recognition and disclosure in ways that affect multi-country groups. Many UK groups keep UK GAAP for stand-alone entities and use IFRS for consolidation. The table highlights practical differences that influence policies, systems and audit files. For assurance deliverables, see Financial Statement.
| Area | UK GAAP (FRS 102) | IFRS |
|---|---|---|
| Revenue recognition | Policy-driven with fewer detailed rules | IFRS 15 five-step model |
| Financial instruments | Simplified categories and disclosures | IFRS 9 classification, hedge accounting detail |
| Leases | FRS 102 Section 20, less pervasive right-of-use | IFRS 16 on-balance-sheet model |
| Consolidation | Exemptions more common for small groups | Full IFRS group reporting expected |
| Disclosures | Generally lighter | Broader and deeper note requirements |
UK GAAP is the UK’s reporting framework. IFRS is the international standard set by the IASB.
