ARKK automates FATCA and CRS reporting for financial institutions, converting fund and account data into validated XML and centralising every jurisdiction into one dashboard. FATCA requires institutions worldwide to identify and report US persons to the IRS. CRS is the OECD's multilateral equivalent, under which over 100 jurisdictions exchange account holder tax residency data with each other.
Most firms still manage this with spreadsheet templates that break when a new jurisdiction joins CRS or a Nil Return is missed. With authorities now using AI to cross-check CRS data against other filings, the cost of an XML error or late submission has never been higher. ARKK removes that risk, validating every return against each jurisdiction's schema before you file.
Aggregate
Centralise all FATCA and CRS data across funds, entities, and jurisdictions into a single, governed data foundation.
Calculate
Determine reportable balances, income, and account values per holder, validated against each jurisdiction's schema for consistency.
File
Submission-ready XML filed to each authority's portal across 100+ jurisdictions, including automatic Nil Returns where required.
Govern
Enterprise-grade governance with full accountability and an audit trail at every stage of the reporting lifecycle.
How the ARKK Automation Platform works
The Platform is modular, so whether you need the full FATCA and CRS process automated or just the final XML conversion, you only implement what you need and go live in weeks.

+ What is FATCA and CRS reporting?
FATCA (Foreign Account Tax Compliance Act) is a US law requiring foreign financial institutions to identify and report information on their US account holders, while CRS (Common Reporting Standard) is the global equivalent covering 110+ participating jurisdictions. Both regimes require institutions to determine the tax residency of their account holders and report balances and income to the relevant authorities to prevent offshore tax evasion. Compliance is annual and submitted in XML, a process that is complex to manage manually across multiple jurisdictions, each with its own portal and schema.
+ How does ARKK automate FATCA and CRS compliance?
The ARKK Automation Platform delivers the complete process in four steps: aggregating data from any source system into a single governed environment, calculating reportable balances and values per account holder, filing submission-ready XML to each jurisdiction's portal, and providing enterprise-grade governance and a full audit trail across every stage. The platform is modular, so institutions can implement the full end-to-end process or simply the final XML conversion.
+ How long does it take to implement ARKK's FATCA and CRS solution?
The ARKK Automation Platform is designed to be operational in weeks, not months. The modular structure means implementation scope is defined by what you need, so institutions that require only the XML conversion component can go live faster than those implementing the full end-to-end process. Your dedicated Customer Success team provides guidance throughout onboarding and extended support around reporting deadlines.
+ Does ARKK integrate with existing fund and data systems?
Yes. The ARKK platform is source-agnostic, connecting to data from any system, whether an ERP, fund administrator feed, or spreadsheet-based process. Data is ingested once and reused across multiple reporting processes without limits on volume or complexity, removing the need to re-extract or reformat data for different jurisdictions.
+ How is data secured on the ARKK platform?
ARKK software is ISO 27001 certified, the internationally recognised standard for information security management. The platform includes customisable workflows, defined team roles, and built-in validations, ensuring that access controls and data integrity are maintained throughout the reporting lifecycle.
+ Does ARKK handle Nil Returns and new CRS jurisdictions?
Yes. ARKK automatically manages Nil Return obligations for jurisdictions such as the Cayman Islands, BVI, and the UK, where a return is required even with no reportable accounts. As new countries join the CRS list, their schemas are added to the platform, so your process does not break when your reporting footprint expands.
+ What are the risks of managing FATCA and CRS in house?
Many institutions still manage FATCA and CRS through spreadsheet templates with scattered ownership and limited controls. As scrutiny intensifies, these approaches create material risk: XML errors and miscategorised data lead to rejected filings, missed Nil Returns trigger easy regulator fines, and manual processes struggle to scale as jurisdictions and account volumes grow. With authorities now using AI to cross-check CRS data against other filings, data quality matters more than ever.
