Why Data Centres Are Different
Data centre operators deal with massive capital expenditures on equipment that may serve multiple purposes (commercial hosting, internal R&D, mixed use). The ITC rules create both opportunities and traps.
Capital Personal Property: The All-or-Nothing Test
Under ETA s.199, capital personal property follows a primary use test:
- If commercial use exceeds 50%: You claim 100% of the ITC
- If commercial use is 50% or below: You claim 0%
For a $2M GPU cluster used 51% commercially, you recover the full ~$100K in GST/HST. At 49%, you recover nothing.
What Counts as Capital Personal Property?
- Servers and server racks
- GPU clusters and AI accelerators
- Network switches and routers
- UPS systems and power distribution
- Cooling equipment (CRAC units, chillers)
Operating Expenses: Proportional Apportionment
Unlike capital property, operating expenses use proportional apportionment:
- Electricity: Claim ITCs based on exact commercial use percentage
- Telecommunications: Same proportional approach
- Rent: Based on commercial use of the leased space
- Maintenance contracts: Based on the use of the maintained equipment
Thresholds
If commercial use is below 10% or above 90%, special rules may apply. Between 10-90%, use the exact percentage.
Import Hardware Documentation (CARM)
Since the CARM (CBSA Assessment and Revenue Management) system launched, importing data centre hardware requires:
- Proper tariff classification
- GST paid at the border documented correctly
- Coordination between customs broker and GST return filing
Missing or mismatched documentation means ITCs on imported hardware get denied.
Simplified Registration Vendors in the Stack
Cloud providers like AWS, Azure, and GCP may be registered under the simplified GST/HST framework. If so, tax they charge is non-recoverable (see our article on simplified registration).
Our Detection Engine for Data Centres
We have 7 dedicated detector types for data centre operations:
| Type | What It Catches |
|---|---|
| Type 20 | BC PM&E software development exemption on GPU clusters |
| Type 21 | Alberta Bill 12 data centre equipment levy |
| Type 23 | Capital property apportionment errors (all-or-nothing test) |
| Type 24 | Operating expense apportionment errors |
| Type 25 | Simplified registration vendor trap (cloud providers) |
| Type 26 | Specified person limitation warning (2-4 year window) |
| Type 27 | CARM import hardware documentation gaps |
