We're looking for a talented Tax Manager to join our Finance team and lead tax compliance and advisory activities across our international footprint.

This is a rare opportunity to step into a broad, autonomous role where you'll work across multiple tax disciplines, partner with senior stakeholders, and gain exposure to complex global tax matters within a growing technology business.

What you'll be responsible for

You'll own tax compliance and governance across Dext's global operations, including:

• Corporate tax, VAT/GST, sales and use taxes, withholding taxes and employment taxes

• Managing compliance across the UK, US, Canada, Australia, New Zealand, Singapore, France, Bulgaria and South Africa

• Leading relationships with external tax advisors and reviewing their work

• Preparing UK corporation tax returns, tax computations and supporting schedules

• Supporting tax provisions, statutory reporting and quarterly cash tax forecasting

• Advising the business on commercial and operational tax matters

• Monitoring legislative changes and assessing impacts to the business

• Supporting transfer pricing, R&D tax credits and tax governance initiatives

• Managing tax audits, enquiries and compliance risk

Approximately 20% of the role will involve supporting wider Group tax activities in partnership with the IRIS Group Head of Tax.

About You

Experience in corporate tax compliance
Exposure to multi-jurisdictional tax obligations
CTA, ACA, ACCA, CPA or equivalent qualification (or qualified by experience)
Strong knowledge of corporate tax and indirect taxes (VAT/GST)
Excellent stakeholder management and communication skills
A proactive, organised and commercially minded approach

Experience gained within a Big 4, mid-tier practice, or an in-house tax function would be beneficial, as would experience within a SaaS, technology or high-growth business environment.
