Altessa’s focus is tax accounting and advisory. Engagements do not include audit, review, or other attest services.
Every engagement begins with the business issue, the reporting deadline, and the people responsible for delivering. The scope follows the work your company needs—not a standard package.
Discuss the milestone, existing reporting process, team capacity, and decisions that need attention.
Agree on priorities, deliverables, responsibilities, and timing. For readiness engagements, identify gaps and sequence remediation.
Work through the technical analysis and reporting tasks, coordinate with stakeholders, and keep open items visible.
Document conclusions, transfer knowledge, and help the team carry the work into the next reporting cycle.
Tax accounting support grounded in the realities of a finance team’s reporting calendar.
Altessa Advisory is a boutique practice focused on IPO readiness, ASC 740, transaction tax accounting, and interim tax leadership.
The approach connects complex accounting questions to practical business decisions. Engagements combine technical analysis, clear documentation, and hands-on execution with your finance and tax teams.
Whether the priority is a public-company milestone, a challenging provision cycle, or a gap in senior leadership, the work is scoped around the deliverables and deadlines that matter.
A defined review of tax accounting, disclosures, processes, and capacity, with prioritized findings and a remediation roadmap.
Senior ownership during a vacancy or transition, or ongoing part-time leadership tailored to your team’s needs.
A clearly scoped provision, transaction, carve-out, technical accounting, or disclosure workstream.
Continuity on technical decisions and reporting priorities across quarterly closes and business changes.
A few practical details about working with Altessa.
No. Altessa also supports private companies and established public companies with tax accounting, provisions, transactions, controls, and interim leadership. IPO readiness is one part of the practice.
Yes. An engagement can complement your internal team, external tax advisers, and auditors. Responsibilities and deliverables are agreed at the outset so the work is coordinated.
Interim support fills a temporary leadership need, such as a vacancy or transition. Fractional support provides ongoing senior involvement on a part-time basis. The cadence and scope depend on your company’s reporting needs.
We first discuss your priorities, deadlines, available information, and required deliverables. The proposal then sets out the scope, responsibilities, timing, and fee arrangement before work begins.
A brief description of the issue, your next reporting or transaction milestone, and where the team needs support. Confidential documents can be shared later through an agreed secure channel.
Tell us about your reporting deadline, transaction, or tax leadership needs. We can discuss the right scope of support for your company.
