Mega Deduction Calculator

The Mega Deduction for construction and trades contractors

Strong years mean big tax bills, and most contractors buy equipment in the fall anyway. Timing those purchases before year-end now erases a large slice of the bill.

Three things to know

  • Excavators, skid steers and lifts you were going to buy in spring are worth more bought in Q4
  • Work trucks and cargo vans that are not passenger vehicles are expected to qualify
  • Tools and shop equipment over $500 (Class 8) go from a 20% write-off to 100%
