Operating System

Senior tax leadership without the senior hire.

ArtisanTaxOS powers fractional Head of Tax engagements for mid-market companies in energy and financial services. Big 4 caliber expertise, embedded in your team, at a fraction of the cost.

The Problem

Your company outgrew its CPA firm. You can't justify a $400K Head of Tax.

Mid-market companies face a brutal gap. The tax complexity of a large enterprise, without the budget for a dedicated tax department. The Big 4 will sell you partner hours at $800/hr with associates doing the work. Regional firms don't have the specialization. You need someone who has sat in the Head of Tax seat, not someone who advises from outside it.

Artisan Tax closes that gap. One embedded leader. Full strategic ownership. No overhead.

Capabilities

What fractional tax leadership actually looks like

01

Embedded Leadership

Not a consultant who drops in quarterly. A fractional Head of Tax who joins your leadership calls, owns the tax function, and drives strategy as if they were full-time.

02

Cash Tax Savings Reviews

Comprehensive reviews that find money left on the table. R&D credits, energy transition incentives, multistate optimization, entity structuring. Real savings, not theoretical models.

03

M&A Tax Diligence

Tax due diligence for acquisitions, divestitures, and restructuring. Identifying exposures and opportunities before the deal closes, not after.

04

Multistate & Energy Tax

Deep specialization in state and local tax for energy companies. Nexus analysis, apportionment strategy, and IRA credit optimization from someone who built the practice at Deloitte.
