Corporate Income-Tax Modeling Reviewer
Job Description
The opportunity
IXO is seeking corporate income-tax practitioners to build realistic work samples and evaluate AI attempts against them. The role follows a company’s facts from source records to tax calculations, supporting documentation and a defensible recommendation.
Work products you will develop
Assignments use simulated trial balances, intercompany contracts and deal files. Within your specialty:
• Calculate quarterly and annual current/deferred tax provisions under ASC 740, including effective-rate reconciliations and jurisdictional cash-tax forecasts.
• Prepare federal-return examples, state apportionment schedules and international tax workpapers, checking that calculations tie to the supplied records.
• Analyze tax attributes and limitations, including NOLs and section 163(j), and relevant cross-border frameworks such as GILTI, FDII, BEAT and Pillar Two for the period specified.
• Examine transfer-pricing and intercompany policies, producing benchmarking analyses, studies and master/local-file documentation.
• Identify acquisition or restructuring tax exposures, develop diligence findings and structuring memoranda, and evaluate uncertain-tax-position reserves under FIN 48.
Deliverables include checked provision and return calculations, transfer-pricing support, diligence findings and decision memos. Explain assumptions and remaining uncertainties so an independent reviewer can reproduce the analysis.
Required and preferred experience
You need at least four years of corporate income-tax experience in-house or at a Big Four firm, with substantive depth in provision/compliance, international tax/transfer pricing or M&A tax. Experience limited to individual returns, payroll tax or sales tax does not qualify.
CPA, a taxation-focused JD or LLM, EA or CTA qualifications are preferred rather than mandatory. Tax-equity experience and hypothetical-liquidation-at-book-value (HLBV) modeling are additional advantages. No single credential substitutes for the required corporate-tax practice.
Assessment may include a provision from a mock trial balance, a transfer-pricing benchmarking memo and a transaction-tax recommendation, reviewed against stated criteria.
Engagement and pay
US-based contributors work remotely with IXO at $105 • $130/hr USD. Approximately 15 hours per week is an indicative planning level; actual scope, hours, duration and rate are agreed before starting. These are evaluation work products, not live filings.
Use public, synthetic or explicitly authorized materials. Do not disclose confidential taxpayer, employer or client information.
