Position Summary

We are seeking a Tax Senior Manager to join our Manufacturing team. The Tax Senior Manager, Manufacturing serves as a strategic leader responsible for overseeing complex, multi‑service tax engagements for manufacturing clients and driving long‑term client and firm success. This role manages executive‑level client relationships, integrates cross‑functional services, and applies advanced technical and industry expertise to deliver high‑value federal, state, and international tax compliance and advisory solutions tailored to manufacturing businesses.

The Tax Senior Manager, Manufacturing acts as a trusted business advisor, develops future leaders, and contributes to portfolio growth, market expansion, and specialty practice development. This position balances exceptional client service with firm priorities while modeling GMCO's values, culture, and commitment to excellence.

What you’ll be doing

• Lead and manage complex, multi‑service tax engagements for manufacturing clients at the executive level—anticipating deliverable timelines, resolving issues before escalation, and aligning internal resources for seamless execution—ensuring compliance with applicable federal, state, and local tax laws, regulations, and firm methodology, and preparing deliverables for shareholder review with accuracy and strategic presentation tailored to the audience.
• Evaluate and provide expert guidance on federal and multi‑state corporate and partnership tax matters for manufacturing clients, including entity structure optimization, cost segregation and fixed asset strategies, IRC Section 199A deductions, UNICAP rules under IRC Section 263A, manufacturing tax credits (including R&D/IRC Section 41 credits and energy credits), and the tax implications of inventory accounting methods; serve as a recognized technical authority in these areas and shape technical strategy across specialty manufacturing engagements.
• Advise on international tax matters relevant to manufacturing clients, including transfer pricing policies, GILTI, BEAT, FDII, and cross‑border supply chain structures; identify exposures and opportunities arising from multinational manufacturing and distribution operations.
• Manage engagement economics with strategic foresight and financial discipline—overseeing pricing, budgeting, billing, scope management, staffing, and workflow efficiency across multiple concurrent complex engagements—optimizing resource allocation and making delivery decisions that balance client needs against GMCO's long‑term profitability goals.
• Build and deepen executive‑level client relationships by proactively tracking evolving client priorities and communicating throughout the year on engagement status, emerging issues, legislative and regulatory developments, and tax planning opportunities specific to manufacturing; influence client strategy, help clients navigate industry‑specific tax trends and regulatory changes, and identify opportunities to enhance their tax positions.
• Act as a trusted business advisor by integrating cross‑functional services, connecting complex client challenges to GMCO's full suite of offerings, and owning portfolio growth targets through cross‑selling, identification of new market opportunities, and leadership of go‑to‑market strategies.
• Lead, mentor, and develop staff, senior associates, and managers through on‑the‑job coaching, internal CPE, engagement and annual performance evaluations, and career development guidance; drive succession planning, offer stretch opportunities, support recruitment of top talent, and build a pipeline of future firm leaders.
• Model ethical leadership and proactive risk management by identifying and mitigating risks, mentoring others in professional conduct, and contributing to external publications and technical forums that advance GMCO's thought leadership and industry presence in manufacturing taxation.
• Champion organizational change and firm culture by contributing practical solutions, modeling adaptability, leading firm‑wide initiatives, and promoting GMCO's brand through industry speaking engagements, published insights, and participation in professional organizations; demonstrate a firm‑first mindset in all resource, delivery, and growth decisions.
• Demonstrate and uphold core values including integrity, quality, innovation, stewardship, and inclusivity in all aspects of client service and team leadership.

What makes you a fit

• Education: Bachelor’s degree in Accounting, Business, Finance, or a related field.
• Experience: A minimum of 7+ years of recent public accounting experience in tax, including demonstrated leadership of complex tax engagements for manufacturing, industrial, or related commercial clients.
• Specialty: Broad and advanced exposure to federal and multi‑state corporate and partnership taxation as applied to manufacturing businesses, including experience with cost of goods sold analysis, inventory method elections (LIFO/FIFO), IRC Section 263A/UNICAP, accounting method changes, tax depreciation strategies, R&D tax credits, energy credits, and manufacturing deductions; recognized expertise across a wide variety of multi‑state tax issues including nexus, apportionment, and combined filing considerations.
• Technical Skills: Advanced technical proficiency in federal corporate and partnership tax compliance, multi‑state income and franchise tax, IRC Section 199A pass‑through deductions, IRC Section 41 R&D credits, cost segregation analysis, bonus depreciation and Section 179 planning, UNICAP computations, ASC 740 tax provisions, transfer pricing fundamentals, GILTI/FDII/BEAT considerations, accounting method changes, and tax research and consulting across multi‑entity manufacturing structures.
• Leadership: Demonstrated experience managing managers and developing future leaders, including succession planning and talent strategy.
• License: Active CPA license required.
• Communication: Exceptional executive communication skills, with the ability to translate complex technical matters into clear, strategic insights for clients and firm leadership; experience contributing to external publications or technical forums a plus.
• Software: Highly proficient with Microsoft Office and tax compliance software platforms (e.g., CCH Axcess Tax, Thomson Reuters UltraTax); adaptable to emerging technologies.
• Project Management: Strong ability to manage multiple complex engagements and competing priorities in a fast‑paced, high‑performance environment.
