Cross-Border Accounting, IFRS/US GAAP & ITIN Support
A foreign parent reporting under IFRS, a U.S. subsidiary keeping GAAP books, owners who need ITINs and a tax footprint on two continents - we work across all of it, in four languages.
Two frameworks, one set of numbers
International groups operating in the U.S. live in two accounting worlds at once: the parent reports under IFRS while the U.S. entity needs US GAAP books - or the reverse. The differences are not cosmetic: revenue timing, lease measurement, impairment models, development costs and financial instrument classification can all diverge. Bridging them badly means consolidation adjustments nobody can explain a year later.
We are specialists in exactly this bridge. Big Four–trained in both frameworks, we build conversion workpapers, dual-reporting processes and policy mappings that make the differences explicit, documented and repeatable - and we support the individuals behind the business with ITIN and IRS services in their own language.
For international businesses
Framework bridging & reporting
- IFRS ↔ US GAAP conversions: full framework conversions and recurring GAAP-to-IFRS (or IFRS-to-GAAP) reporting packages for consolidation
- Policy mapping: a documented bridge - standard by standard - between parent and subsidiary accounting policies
- US subsidiary setup: entity structure, accounting systems and tax registrations for inbound businesses
- Multi-currency accounting: functional currency assessment and FX translation done correctly
Cross-border tax
- Inbound structuring support: coordinating with your home-country advisors on how the U.S. piece fits
- U.S. compliance: federal and state filings for foreign-owned entities, including the information returns that carry severe penalties when missed
- Withholding and treaty positions: getting the paperwork right before payments cross the border
For international individuals & families
ITIN & IRS support, in your language
- ITIN applications and renewals: end-to-end preparation with document guidance - see our dedicated ITIN services page
- IRS correspondence: notices, penalty abatement and representation handled confidently
- Multi-language service: English, Arabic, Spanish and Chinese - the whole engagement, not just the brochure
- State residency questions: part-year and dual-residency filings when you move into or out of a state mid-year

Frequently Asked Questions
Our parent company reports under IFRS. Can you keep our U.S. books in GAAP and still feed the consolidation?
Yes - that is one of our most common engagements. The U.S. entity gets proper GAAP books for its own statutory and tax needs, and we maintain a documented conversion bridge that produces the IFRS reporting package your group consolidation needs each period, on the group’s timetable.
I need an ITIN for myself and my spouse. Do we have to mail our passports?
Usually not - there are alternatives to mailing original documents, and we walk you through exactly which route fits your documents and timeline. Our ITIN application guide covers the process step by step, and we handle the application end to end.
Which languages do you actually work in?
English, Arabic, Spanish and Chinese - and that means the actual work: meetings, explanations and correspondence, not just a translated homepage. Technical deliverables (memos, financial statements) are in English as U.S. practice requires.
