Overview
Dr. Sarah Williams is a tenured professor at Mississippi State University who also consults for various institutions across the country. When she came to us, she was struggling with:
- W-2 income from MSU plus 1099 income from consulting work
- Multi-state tax filing requirements (Mississippi, Tennessee, Alabama)
- Complex retirement contribution options (403(b), 457, IRA)
- Educator expenses and professional development costs
- Student loan interest deduction eligibility
Without proper planning, she was overpaying taxes and missing valuable deductions. She needed expert guidance to navigate her complex tax situation.
The Challenge
Professor taxation involves several complex considerations:
- Multi-State Filing: Properly allocating income and avoiding double taxation across multiple states

- Business vs. Employee Expenses: Determining what consulting expenses are deductible
- Educator Deductions: Understanding available deductions specific to educators
Our Approach

- Deduction Maximization
- Tax Planning
1. Multi-State Tax Coordination
We analyzed all state filing requirements:
- Determined which states required filing based on consulting work
- Properly allocated income to avoid double taxation
- Claimed appropriate credits for taxes paid to other states
- Ensured compliance with Mississippi resident filing requirements
2. Retirement Contribution Strategy
We maximized Dr. Williams' retirement savings:

3. Deduction Identification
We identified numerous overlooked deductions:
