CARF | ARKK

ARKK converts crypto-asset transaction and user data into validated XML for CARF reporting, centralising every jurisdiction into one dashboard. Most firms have no existing process for CARF, the tax transparency regime modelled on CRS, and the first CARF report is due by 31 May 2027.

Manual or spreadsheet-based reporting can't keep pace with transaction volumes or shifting jurisdiction schemas, and a late or malformed return invites regulator penalties. ARKK validates every return against each jurisdiction's schema before you file, removing that risk.

+ What is CARF reporting?

CARF (Crypto-Asset Reporting Framework) is an OECD-led tax transparency initiative requiring crypto-asset service providers to identify and report information on their crypto-asset users, similar in structure to FATCA and CRS but built specifically for digital assets. Institutions must determine user tax residency and report transactions and balances to the relevant authorities to prevent offshore tax evasion via crypto-assets. 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 CARF 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 CARF 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 crypto and data systems?

Yes. The ARKK platform is source-agnostic, connecting to data from any system, whether an exchange platform, wallet provider 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.

+ What are the risks of managing CARF?

Many crypto-asset service providers still manage reporting through home-grown spreadsheet templates with scattered ownership and limited controls. As scrutiny intensifies, these approaches create material risk: XML errors and miscategorised transactions lead to rejected filings, missed reporting obligations trigger easy regulator fines, and manual processes struggle to scale as jurisdictions and transaction volumes grow. With authorities increasingly cross-checking data against other filings, data quality matters more than ever.
