CCA Class 50 (55%): Computers & Systems Software

The fastest mainstream CCA class — and right now it's faster than its own rate: computer hardware acquired after April 15, 2024 and in use before 2027 is 100% deductible in year one.

What Goes in Class 50

The statute calls it "general-purpose electronic data processing equipment and systems software" — acquired after March 18, 2007. In practice:

  • Laptops, desktops, and workstations
  • Servers, on-premise storage, and rack hardware
  • Monitors, printers, scanners, and other directly-connected peripherals
  • Systems software — the operating system that ships with the machine

What people put here by mistake:

  • Application softwareClass 12, at 100%
  • Network switches, routers, and cabling — Class 46, at 30% (currently sharing the same 100% first-year window)
  • Phones — usually Class 8; smartphones sit near the boundary, so pick a position and apply it consistently
  • Point-of-sale terminals and specialized control hardware — often Class 8, because they aren't "general-purpose"

The 100% Window, and What Follows It

Budget 2024 made computers one of three "productivity" classes (44, 46, 50) eligible for full first-year expensing: acquired after April 15, 2024, available for use before January 1, 2027. Buy $8,000 of laptops in 2026, deduct $8,000 in 2026 — no schedule, no remainder.

Miss the window and Class 50 is still quick. Under the Reaccelerated Investment Incentive (through 2029), year one claims 1.5× the 55% rate:

$8,000 of Hardware, Bought InYear 1Year 2Year 3
2026 (100% expensing)$8,000.00
2027 (RIIP, 82.5%)$6,600.00$770.00$346.50
2018 (half-year rule, for contrast)$2,200.00$3,190.00$1,435.50

Same $8,000 either way — the difference is purely when you get it. For hardware you're planning to buy anyway, the 2026 deadline is a real scheduling consideration.

Class 50 Gotchas

  • Fully expensed hardware still walks out the door. Laptops are the most-lost, most-stolen asset category a business owns. A zero UCC doesn't end the need to know who has which machine.
  • Selling old hardware creates income. Once the pool is at zero, any proceeds from selling machines come straight back as recapture.
  • Old registers carry old computer classes. Depending on vintage, earlier machines sit in Class 10, 45, or 52 — if you inherited an old asset list, don't assume everything labelled "computer" is Class 50.

Class 50 Questions

Laptops, desktops, servers, monitors, and printers are Class 50 — general-purpose data processing equipment and its ancillary hardware. Phones are usually Class 8: common practice treats cell phones as ordinary equipment, though smartphones sit close to the Class 50 boundary. Network switches and routers are Class 46, which currently shares Class 50's 100% first-year window. The base rates (20%, 30%, 55%) diverge again after 2026, so the sorting is worth doing carefully.

Hardware must be acquired after April 15, 2024 and available for use before January 1, 2027. A computer bought in 2026 qualifies; one bought in 2027 falls back to the Reaccelerated Investment Incentive — 82.5% in year one (1.5× the 55% rate) through 2029. If a meaningful hardware refresh is coming, doing it before the end of 2026 deducts the whole cost at once.

Only systems software — the operating-system layer acquired with the hardware. Application software you buy outright (accounting, design, industry tools) is Class 12 at 100%. Cloud subscriptions are current expenses, not capital assets at all.
