Mega Deduction Calculator

Medical and dental equipment: eligible

Clinic equipment is mostly Class 8 at 20%. A professional corporation buying a $150,000 imaging unit used to deduct $15,000 in year one; under the Mega Deduction it deducts the full $150,000.

Examples of clinical and diagnostic equipment

  • dental chairs and CAD/CAM milling units
  • imaging equipment (CBCT, ultrasound, digital X-ray)
  • lasers, autoclaves and sterilization systems
  • physiotherapy and rehab equipment

Planning tip

Professional corporations still pay the small business rate on eligible income, so the deferral is worth less per dollar than for a general-rate corporation. Run both scenarios.

CCA Class 8 · regular rate 20% declining balance · half-year rule normally applies in year one.
