- Support the configuration, administration, optimization, and ongoing maintenance of Onesource Tax Provision and Onesource Income Tax, including templates, data imports, mappings, workflows, provision-to-return processes, troubleshooting, upgrades, and user support.
- Partner with tax stakeholders to understand process requirements, ask relevant tax and data questions, and translate business needs into scalable, controlled technology solutions.
- Extract, map, transform, validate,



and reconcile financial and tax data from general ledger, trial balance, investment, actuarial, and other source systems.
- Develop solutions using Microsoft 365 tools, Power Platform, Power BI, and approved artificial intelligence tools such as ChatGPT, Claude, and Microsoft Copilot.
- Evaluate and apply emerging technologies, including generative AI, to appropriate tax use cases while maintaining strong controls, documentation, reviewability, and data governance.
- Support quarterly and annual income tax close processes, including data preparation, validation, reconciliations, workpaper development, and issue resolution.
- Troubleshoot system, workflow, and data issues; identify root causes and coordinate timely resolution with tax, finance, accounting, information technology, vendors, and third-party consultants.
- Develop and maintain process documentation, standard operating procedures, control documentation, user guides, and training materials for tax systems and automation solutions.
- Provide training and ongoing support to tax users to promote adoption, consistent execution, and effective use of new tools and processes.
- Assist with system implementations, enhancements, integrations, testing, and technology rollouts, including coordination with external consultants.




- Contribute to other tax technology, transformation, and special projects as needed.

- Familiarity with ASC 740, corporate income tax compliance, consolidated federal income tax returns, book-to-tax adjustments, and related tax accounting concepts.
