What WTS Hansuke does

WTS Hansuke (legal entity: Hansuke Consulting Limited) is a UK-based financial services consulting firm headquartered in the City of London with a registered office in Watford. Founded in 2016 and operating as a member firm of the WTS Global tax practice network — which spans 100+ countries — the firm specializes exclusively in tax advisory, compliance, and regulatory reporting for financial institutions. Its core client base comprises investment banks, prime brokers, custodians, fund administrators, and capital markets participants, with service lines covering tax compliance and advisory, tax transparency (FATCA/CRS/AEOI), investment taxes, tax integrity, tax outsourcing, assurance, and capital markets advisory (securities lending, repo, collateral, EMIR/REFIT, T+1 settlement).

The firm's core technology offering is its proprietary AEOI Reporting Service, which automates FATCA and CRS compliance across 80+ jurisdictions. It uses up-to-date regulatory schemas, generates XML lodgement files with human-readable documentation, and is hosted on a Citrix ShareFile secure portal with double-layered passwords and a digital audit trail for tax administration inquiries. The Digital services practice extends this into process automation (RPA/low-code), data strategy, data quality, vendor selection, and outsourcing, with stated use of AI for pattern matching and anomaly detection in regulatory, finance, and tax data. The firm also operates the Tax Files Podcast, hosts the annual Financial Services Tax Conference (FSTC), runs the Hansuke Gakkō training academy, and publishes whitepapers on emerging regulatory regimes such as the German MiKaDiv withholding tax and UK CRS 2.0.

WTS Hansuke operates on a professional services model (quote-based project engagements and ongoing advisory retainers) combined with managed-services revenue from AEOI reporting. The go-to-market is sales-led, targeting CFOs, Heads of Tax, and tax directors via direct advisory engagement, industry conferences, webinars, and thought leadership content. The firm is ICAEW accredited and GDPR compliant, with no disclosed external funding or institutional ownership — it operates as an independently-managed boutique within the WTS Global network.
