James Harnsberger. Enrolled Agent.
James Harnsberger is a tax professional and strategic consultant with more than thirty years of experience in the U.S. tax system. As an Enrolled Agent — the credential conferred directly by the U.S. Department of the Treasury — he holds unrestricted rights to represent taxpayers before the Internal Revenue Service at every administrative level. His work is defined by clinical precision and a deep mastery of tax law, with a practice focused on high-stakes IRS Appeals and sophisticated Business Tax Planning.
Core credentials
Federally licensed tax practitioner authorized by the U.S. Department of the Treasury. EAs are the only tax professionals licensed directly by the federal government to represent taxpayers at every administrative level of the IRS.
A graduate of the National Tax Practice Institute. The designation is reserved for practitioners who have completed the Institute's three-year curriculum in taxpayer representation and defense.
A specialized legal framework applied to tax documentation, procedural compliance, and the construction of administrative records.
Trained in the methodology of business valuation — a discipline central to mergers, acquisitions, and estate planning.
Areas of expertise
IRS Appeals & Representation
James has spent more than two decades inside audits, examinations, and the appeals process. He works on behalf of taxpayers in emerging and high-scrutiny areas, including Cryptocurrency Tax Consulting and Foreign Bank Account Reporting (FBAR). His approach is proactive: corrective action taken before an investigation begins, with attention to the safe-harbor protections built into IRS procedure.
Strategic Business Tax Planning
As CEO of ITWS Financial Services and SMIB Management, Inc., James integrates advanced tax models into operational business strategy. His work spans:
• Accountable Reimbursement Plans (ARP) and Medical Expense Reimbursement Plans (MER).
• Section 475 Elections for professional traders.
• Industry Segmented Assessment Modeling (ISAM) — a proprietary methodology for deep-dive business analysis.
Innovation in Financial Technology
James works at the intersection of tax law and artificial intelligence. He is the architect of the ATLAS-5 platform, an agentic AI framework designed to automate complex multi-tiered workflows while holding to a standard of visibility, measurability, and accountability.
The VMA standard
James operates under the VMA Standard — Visibility, Measurability, Accountability. Whether he is structuring a Special Purpose Corporation for a family office or defending a client in a civil fraud examination, the work is bound to those three principles: every step traceable, every outcome measurable, every recommendation attributable.
James is also an accomplished visual artist. He works in psychological cartography — pen and ink, intricate, structurally dense — and in acrylic painting, including the fair-entered Vertical Pulse.
The same instinct that draws him to those forms shows up in his tax practice: the precision, the structural depth, the willingness to spend hours mapping a system until its logic is visible.
“Taxation is not just a statutory obligation; it is a landscape of complex variables that require both mathematical precision and strategic foresight.”
Professional licensing & representation
Atlas One is a tax professional firm led by an Enrolled Agent (EA). Enrolled Agents are federally authorized tax practitioners who have demonstrated technical expertise in the field of taxation. Unlike attorneys and CPAs, who are state-licensed, EAs are the only tax professionals licensed directly by the U.S. Department of the Treasury to represent taxpayers before all administrative levels — including examination, collection, and appeals — of the Internal Revenue Service.
How we work
Atlas One serves a small number of ultra-high-net-worth families. We do not custody assets, sell securities, or accept commissions. We work alongside your existing counsel — attorneys, CPAs, bankers, and family-office staff — with a brief that arrives every morning, a partner that answers personally, and a strategist that remembers everything.
