The Opportunity: We are building a modern, digital-first tax service to support sole traders and self-employed individuals ahead of Making Tax Digital (MTD) for ITSA in 2026. To make this a reality, we are hiring our first Tax Operations Manager, a senior tax specialist who will design, implement and manage the operational and compliance foundations of the Bolst Tax service.

This role is ideal for someone who thrives in early-stage environments: someone who can build structure from scratch, collaborate closely with cross-functional teams, and confidently manage tax service partners while owning the compliance and operational backbone of a new service.

You will work closely with the Head of Growth, Product, Operations and our tax service partners to create scalable workflows, ensure HMRC and AML compliance, and prepare the business for significant growth as we enter the MTD era. This is a pivotal position shaping the future of Bolst Tax within Indigo, with significant opportunity for career growth.

What You Will Lead:

• Operational Model & Service Design: Shape the end-to-end operational model for the Bolst Tax service. Build scalable processes, controls and workflows aligned to HMRC requirements.

Support non-MTD for ITSA workflows and compliance requirements.
• Compliance, Governance & HMRC Engagement: Act as the primary HMRC Representative for Bolst, including responding to compliance checks and enquiries. Support the MLRO by helping define and manage AML processes and partner oversight. Ensure the service meets all regulatory requirements for SA returns for sole traders, self-employed individuals and landlords. Develop audit and governance processes, including QA checks, risk controls and auditing frameworks.
• Outsourced Partner Management: Manage and oversee performance of our tax preparation outsource partners. Oversee the additional outsource partners responsible for independent QA auditing. Build strong relationships, ensuring delivery against SLAs, KPIs and compliance standards. Contribute to the evaluation and onboarding of future partners as the service scales.
• Product & Cross-Functional Collaboration: Work closely with the Product team, providing tax expertise to shape compliant workflows and user journeys. Participate in discovery workshops, requirement reviews and testing of compliance outcomes. Collaborate with Customer Success, Operations and Growth teams to ensure smooth, accurate and efficient service delivery.
• Operational Leadership & Future Team Growth: Provide day-to-day leadership of tax operations, ensuring continuous improvement and high-quality delivery. Support the creation of documentation, SOPs and internal knowledge bases. As the division grows, contribute to hiring, mentoring and supporting a blended tax/operations team.

• Strong technical expertise in Personal Tax and Self Assessment for sole traders, self-employed individuals and landlords.
• Experience managing tax operations, compliance frameworks or outsourced tax delivery.
• A solid understanding of AML, governance, risk and HMRC requirements.
