Manager - Tax

Iberdrola•Boston, MA

About The Position

This role leads the management of all Networks segment sales and use tax responsibilities, including tax compliance, cost recovery, tax planning, audit defense, risk mitigation, and financial reporting (both GAAP and IFRS). The Tax Manager provides strategic insight and technical leadership through close cross-functional collaboration with Regulatory, Finance, Accounting, Supply Chain, Procurement, Legal, Engineering, Capital Accounting, and IT teams to ensure accurate tax treatment of complex utility transactions and effective recovery of indirect tax costs in customer rates. The Tax Manager oversees sales and use tax budgets, forecasts, accruals, and cost recovery projections, with a strong focus on supporting regulatory filings, rate cases, and jurisdictional reporting requirements. This role leads sales and use tax audits, refund opportunities, voluntary disclosures, exemption management initiatives, and dispute resolution efforts, while proactively identifying and managing tax risk and exposure. The role is directly responsible for supporting information requests (IRs), writing testimony, and analyses in rate cases, requiring the ability to clearly explain tax positions, assumptions, and methodologies to regulators and internal stakeholders. An important aspect of this role is leading technology-enabled process improvements that enhance how sales and use tax data is gathered, validated, controlled, and reported to meet regulatory requirements. This includes strengthening data requirements, governance, controls, and reporting tools, optimizing tax and financial systems, and transitioning work from external service providers to a scalable, high-performing in-house sales and use tax function. The Tax Manager serves as a sales and use tax subject matter expert and will provide testimony in rate cases, as needed, translating complex tax and regulatory concepts into clear, well-supported narratives. This role requires a strong, agile, and strategic manager capable of navigating complexity, balancing compliance, and cost recovery objectives, and building sustainable internal capability.
