The Foundation of Precision: Education & Technical Mastery

Bridging the gap between complex financial standards and advanced information systems to provide audit-proof business intelligence.

Osheen Haghnazarian

Founder and Principal Tax Strategist

Osheen Haghnazarian is the founder of Osheen’s Taxes, a Glendale-based firm specializing in advanced tax planning, S-Corp strategy, and fiduciary compliance. As a CTEC Registered Tax Preparer in the State of California with an active PTIN (Preparer Tax Identification Number) from the IRS, Osheen ensures that every return is filed with strict adherence to state and federal regulations.

In an era of digital finance, high-level tax strategy requires more than just an understanding of the tax code; it requires a deep mastery of the systems that power modern business. My dual-background in Accounting and Computer Information Systems allows me to analyze your financial health from both a regulatory and a structural perspective.

Professional Regulatory Frameworks

My practice is built upon strict adherence to the highest global and domestic financial standards. I apply these frameworks to ensure every client’s records are prepared with the same rigor expected of public corporations:

  • Reporting Standards: Comprehensive application of GAAP (Generally Accepted Accounting Principles) and IFRS (International Financial Reporting Standards).
  • Auditing Excellence: Mastery of GAAS (Generally Accepted Auditing Standards), PCAOB (Public Company Accounting Oversight Board) standards, and Forensic Audit methodologies.
  • Compliance & Controls: Deep knowledge of SOX (Sarbanes-Oxley) compliance and the COSO internal control framework to mitigate risk and prevent financial errors.

Accounting Information Systems & Data Architecture

I leverage advanced technology to streamline financial workflows and provide geospatial/temporal analysis that national tax chains cannot offer:

  • Systems Development: Expertise in the SDLC (System Development Life Cycle) and Agile methodologies including SCRUM, RAD, and JAD to optimize business processes.
  • Big Data & Analytics: Proficient in Apache Hadoop, Hive, Pig, and MapReduce, utilizing IBM Bluemix cluster computing and Tableau for high-level data visualization.
  • Enterprise Software: Advanced command of ERP systems, SAP, QuickBooks, SQL, Python, and Java.
  • IT Infrastructure: Comprehensive understanding of Network & IT communications, including AWS, Athena, and LAN/Firewall configuration to ensure your financial data is secure.

Advanced Digital Strategy Toolset

To manage complex marketing and business operations for my clients, I utilize a world-class tech stack:

  • Ad-Tech & Search: Kenshoo, Marin Software, SearchForce, and Omniture Search Center.
  • Development & Design: React/React Native, Adobe Photoshop, Zeplin, and Miro.
  • Workflow & Logistics: Jira, Asana, VersionOne, and MS Visio for architectural mapping.

Why This Matters for Your Business

When you work with Osheen’s Taxes, you aren't just getting a tax preparer. You are gaining a Systems Auditor who understands how your data flows from your server to your bank account and, ultimately, to your tax return. This ensures that your S-Corp or Trust is not only compliant but also optimized for the digital economy.
