What you’ll be doing

• Lead and manage tax engagements for manufacturing clients across the full engagement lifecycle — planning, issue identification, technical analysis, workpaper preparation, and final deliverable review and sign-off — ensuring compliance with applicable federal, state, and local tax laws, regulations, and firm methodology, and preparing deliverables for shareholder review with accuracy and professional presentation tailored to the audience.
• Evaluate and advise on federal and multi-state corporate and partnership tax matters for manufacturing clients, including entity structure considerations, UNICAP rules under IRC Section 263A, IRC Section 199A deductions, manufacturing-related tax credits (including R&D/IRC Section 41 credits and energy credits), tax depreciation planning, inventory accounting method elections (LIFO/FIFO), and multi-state income tax compliance; prepare and review workpapers supporting federal and state compliance filings.

• Manage engagement economics with financial and operational discipline — overseeing pricing, budgeting, billing, scope management, staffing, and workflow efficiency across multiple concurrent engagements — while driving accountability and timely execution against profitability targets.
• Develop relationships with client executives by proactively communicating throughout the year on engagement status, emerging issues, legislative and regulatory developments, and tax planning opportunities specific to manufacturing; help clients understand relevant industry trends and emerging issues, identify opportunities to enhance their tax positions, and leverage prior engagement history to improve continuity and client experience.
• Collaborate across service lines to deliver integrated solutions, identify opportunities to connect client needs to GMCO's broader service offerings, and view all interactions — including networks and proposal opportunities — as potential avenues for business growth.
• Lead, mentor, and develop staff and senior associates through on-the-job coaching, internal CPE, engagement and annual performance evaluations, and career development guidance; coordinate scheduling, support recruitment of quality talent, model professionalism and work-life balance, and hold team members accountable to performance and deadlines.
• Demonstrate and uphold core values including integrity, quality, innovation, stewardship, and inclusivity in all aspects of client service and team leadership.
