Who We Help
This website uses cookies to ensure you get the best experience
Full-cycle preparation, review, and submission of FATCA reporting (IRS, via IDES/XML) and CRS/AEOI reporting. Plus: GIIN registration and restoration, FATCA certification support, and reporting corrections for prior periods.
HOW WE SOLVE IT
A structured, end-to-end review of your client classification, due diligence procedures, internal documents, core-system logic, and client files against FATCA and CRS requirements. Delivered as a written report with a clear, prioritised remediation roadmap.
HOW WE SOLVE IT
Retainer-based advisory: written and verbal responses to compliance questions as they arise, monitoring of regulatory changes in your jurisdiction, review of unusual client situations, and support ahead of regulator reviews or certification cycles.
HOW WE SOLVE IT
Practical, institution-specific training programs for Responsible Officers, compliance teams, and front- and back-office staff. Covers FATCA and CRS requirements, client identification procedures, self-certification forms, reporting, and documentation. Delivered online or in person; includes written materials and post-training Q&A.
HOW WE SOLVE IT
TINcheck: automated TIN format validation across 160+ jurisdictions, for individuals and entities. Validates formats, provides document guidance per country, checks the legitimacy of stated reasons for no TIN, covers local equivalents, and supports bulk checks. Available online (SaaS) or installed inside your own systems.
HOW WE SOLVE IT
Compliant, regulator-ready internal policies, operational procedures, KYC and self-certification forms (individuals and entities), and a defensible client classification and beneficial-ownership methodology — tailored to your institution type.
HOW WE SOLVE IT
Business requirements (functional specifications) for automating your FATCA/CRS processes: core-banking integration, self-certification form autofill, client classification workflows, TIN validation, and regulatory reporting generation. Technology-agnostic; works with any core system.
HOW WE SOLVE IT
For Financial Institutions
Your team checks foreign Tax Identification Numbers by hand, using outdated references — wrong formats and invalid 'no TIN' reasons go undetected until they become reportable errors
TIN Verification — TINcheck
Compliance knowledge sits with one person — and the team can't execute consistently when that person isn't available
Staff Training
Manual processes mean errors, delays, and staff time that doesn't scale — especially as client volumes grow
Automation & Systems
Your internal documents, KYC forms, and self-certification questionnaires were written years ago and haven't kept up with the rules
Policies, Procedures & Forms
Filings get rejected, submitted late, or built on data that doesn't hold up — and each error compounds the next
Regulatory Reporting
You can't see your own exposure until a regulator does — and by then the damage is done
Compliance Gap Audit
Every engagement is scoped to your specific situation. Below is what we deliver —
and the problem each service solves.
and the problem each service solves.
What We Do
Specific, practical guidance for US persons abroad and non-US persons with US accounts or structures: FATCA implications, FBAR obligations, account documentation, and what your financial institution expects from you.
HOW WE SOLVE IT
A clear, written summary of what is reported about you under FATCA and/or CRS — which accounts, which jurisdictions, what information, and what it means for your tax position.
HOW WE SOLVE IT
A formal tax residency determination across the relevant jurisdictions, applying domestic rules and treaty tie-breaker tests. Delivered as a written opinion with the factual and legal basis.
HOW WE SOLVE IT
Tax-aware planning before the move: residency exit and entry analysis, reporting obligations in each jurisdiction, structure review for businesses expanding across borders, and coordination with local advisors where needed.
HOW WE SOLVE IT
A move — personal or corporate — triggers tax and reporting consequences that most advisors don't anticipate until after the move is done
Relocation & Cross-Border Structuring
Two or more countries claim you as a tax resident, and you have no defensible position if either authority asks
Tax Residency & Treaty Analysis
You don't know exactly what your financial institution reports about you, to which countries, or what tax authority sees that data
Exposure Review
For Individuals & Businesses
Three steps — from first contact to a resolved situation
Compliance isn't a one-time event. We offer ongoing retainer advisory to keep your framework current as regulations evolve, your client base grows, or your personal situation changes. Many clients start with a one-off project and move to retained support.
3. Support
You receive the deliverable: an audit report, a compliance framework, regulatory filings, written guidance, or a training program — whichever matches your engagement. Everything is specific to your situation. No generic templates.
2. Solve
We start with a focused intake: understanding your institution type, jurisdiction, current processes (or personal situation), and where the gaps are. For institutions, this includes a document and system review. For individuals, it's a structured fact-gathering session. You don't need to prepare anything in advance — we guide the process.

FAQ
FATCA is a US law that requires financial institutions worldwide to identify and report on accounts held by US taxpayers. CRS is the OECD's global standard for automatic exchange of financial account information between 100+ countries. Both require financial institutions to classify clients, conduct due diligence, and submit regulatory reports. Most institutions must comply with both simultaneously.
Yes. Our practice is international by design. We have delivered projects for financial institutions in the UAE, Kazakhstan, Armenia, Cyprus, the Cayman Islands, and others — and we advise institutions remotely across Europe, Asia, and the Gulf. FATCA and CRS obligations are generally the same regardless of where an institution is based.
Yes — remediation is core to what we do. We can review what went wrong, help correct past filings, fix the underlying process, and prepare your institution for what comes next. Starting from a problem is normal; the earlier we look at it, the more options you have.
If you hold financial accounts outside your country of tax residence, the institution holding those accounts is required to report them to your home tax authority under CRS. If you have a US connection, FATCA creates additional reporting obligations. The consequences range from unexpected tax assessments to access problems with foreign accounts. We help you understand exactly what is reported and what it means for your specific situation.
Both. For financial institutions, we can prepare and support the full reporting cycle — FATCA (IRS IDES/XML) and CRS/AEOI — or advise on the process while your team executes. For individuals, we provide written guidance and, where relevant, coordinate with local tax advisors.
It starts with a consultation — usually 60–90 minutes — to understand your situation. We then scope the engagement and send a proposal. Most projects run 2–8 weeks depending on complexity. Retainer arrangements are available for ongoing support.
CARF (Crypto-Asset Reporting Framework) is the OECD's new standard for automatic exchange of information about crypto-asset transactions. It is expected to take effect for reporting in 2027 in most adopting jurisdictions. Crypto exchanges, brokers, and wallet providers that handle transactions for clients in participating countries will be required to report. If your institution operates in the crypto space, the time to start preparing is now — the implementation work is substantial.
Yes. All engagements are confidential. NDAs are available on request and are standard for institutional clients.
