Mega Deduction Calculator

Computer equipment: eligible

Computer hardware sits in CCA Class 50. Before immediate expensing it was written off at 55% declining balance with the half-year rule, so most of the cost dragged into years two and three. Under the Mega Deduction the whole invoice is deductible in the year the equipment is available for use.

Examples of computers, servers and laptops

  • workstations and laptops
  • servers and NAS storage
  • GPU rigs for AI, rendering or simulation
  • monitors, docking stations, networking switches

Planning tip

Hardware ordered but still in transit at year-end is not 'available for use'. Take delivery and set it up before your fiscal year closes.

CCA Class 50 · regular rate 55% declining balance · half-year rule normally applies in year one.
