  • Graduation from ADA-accredited dental school
  • Active license in good standing for 5+ years
  • No disciplinary actions or pending investigations
  • Completion of Illinois jurisprudence examination

Records must remain accessible to patients upon request. Purchase agreements should specify post-sale records access procedures.

Patient Notification Guidelines

• Notify active patients (seen within 24 months) via mailed letter 30 days before transition
• Post practice sale notice in office waiting area
• Update practice website and phone greetings
• Ensure HIPAA-compliant records transfer procedures

Tax Considerations for Illinois Sellers

Illinois tax treatment of practice sales requires careful planning to minimize tax burden.

Illinois State Income Tax

• Flat Rate: 4.95% on all income including capital gains (as of 2024)
• No Preferential Capital Gains Rate: Illinois taxes capital gains as ordinary income
• Local Taxes: Some Illinois municipalities impose additional taxes; verify local requirements

Tax Calculation Example:

• Practice sale capital gain: $600,000
• Illinois state tax: $600,000 × 4.95% = $29,700
• Federal long-term capital gains (assuming 15% bracket): $90,000
• Total estimated tax burden: $119,700

Property Tax Considerations

If your practice includes real estate:

• Illinois property taxes are among the nation's highest (2nd highest property tax burden nationally)
• Real estate sale may trigger reassessment concerns
• Consider 1031 exchange if reinvesting in like-kind property
• Separate real estate from practice sale for tax optimization

Tax Planning Strategies

• Asset Allocation: Negotiate purchase price allocation to maximize goodwill (capital gains treatment) and minimize equipment recapture (ordinary income)
• Timing: If possible, sell in lower-income years to minimize capital gains bracket
• Installment Sales: Spread gain over multiple tax years through seller financing
• Retirement Planning: Maximize 401(k) and IRA contributions in sale year
• Charitable Strategies: Donor-advised funds or charitable remainder trusts for philanthropic goals

Professional Guidance Essential: Work with Illinois-based CPA experienced in dental transitions. Illinois tax rules combined with federal treatment create complexity requiring specialized expertise.

Common Mistakes Illinois Sellers Make

• Weak patient communication: Poorly managed transitions cause 20-30% patient attrition.

Chicago-Specific Considerations

Chicago practices have unique factors:

• Commercial Lease Complexity: Chicago leases often include percentage rent, common area maintenance escalations, and complex assignment provisions. Legal review essential.
• Parking Premium: Practices with dedicated parking command significant premiums in Chicago's dense neighborhoods.
• Neighborhood Demographics: Chicago neighborhoods vary dramatically in demographics and economics—know your market.
• Insurance Networks: Chicago has high managed care penetration—understand your network contracts and reimbursement rates.
