SR&ED in cloud computing and infrastructure
Distributed systems, container orchestration, fault tolerance, cost per request: cloud engineering teams spend a large share of their time solving problems with no known solution. That is the definition of experimental development under SR&ED.
- Distributed architecture and fault tolerance
- Orchestration, scaling and load optimisation
- Multi-tenancy and data isolation
SR&ED applied to cloud computing
SR&ED is Canada's federal tax credit for scientific research and experimental development. A Canadian-controlled private corporation recovers up to 35 % of its qualifying expenditures as a refundable cash payment, on a base of up to $6M per year; in Québec, the CRIC adds 30 % on the first $1M. In cloud computing the base is almost entirely engineering salaries — which makes the split between qualifying work and routine operations the single decision that drives the final number.
- 01
Reliability engineering is under-claimed
Designing a failure-recovery mechanism that holds at scale without degrading latency is not maintenance. Most SRE teams book that work to "operations" out of accounting habit and remove it from the base without noticing.
- 02
Performance as technological uncertainty
When a latency or cost-per-request target cannot be met by documented means, the search for an architecture that meets it qualifies — including the approaches abandoned along the way.
- 03
Servers are not qualifying expenditures
Hosting, rented instances and licences cannot be claimed under SR&ED, contrary to a stubborn belief in this sector. What is claimable is people’s time. A claim that inflates the base with cloud invoices simply loses that line.
Examples of eligible projects
Work that commonly qualifies among our clients in this sector. This list illustrates; it does not enumerate. A project absent from it is not a project excluded.
Commonly qualifying in this domain
- Designing a distributed consistency or replication mechanism
- Scheduling and autoscaling under highly variable load
- Reducing tail latency where known optimisations fail
- Multi-tenant architecture with strict data isolation
- A migration requiring a rewrite of a component with uncertain behaviour
- High-throughput observability without degrading the observed system
The sector trap: claiming the migration itself. Moving an existing workload to a cloud provider by following a documented procedure is integration work, not SR&ED. What qualifies is the component you had to design because no procedure existed.
Frequently asked questions
Part of it. Routine operations — monitoring, patching, standard deployments — do not. Designing a deployment, recovery or scaling mechanism whose behaviour cannot be predicted from known practice is experimental development. The question is never the job title; it is the nature of the problem being solved.
No. Hosting, rented instances, storage and software licences are not qualifying SR&ED expenditures. The programme funds salaries of personnel engaged in the work, contracted R&D and materials consumed. This is the most common error in cloud sector claims.
No. Assembling existing building blocks is not SR&ED, but nothing requires you to build everything yourself. If integrating those services raises a problem whose solution cannot be derived from their documentation — a behaviour under load, an undocumented limit, a consistency constraint — the work of resolving it still qualifies.
It is an advantage rather than a problem. Pull requests, tickets, load-test results and architecture decision records are contemporaneous, dated evidence that no memo written after the fact can match. What is almost always missing is the explicit link between those traces and the uncertainty they were resolving — that layer has to be added during the year.
Hubvention is a Canadian firm specialised in public R&D funding. We work inside your engineering tools to separate qualifying work from operations, rather than having someone estimate a time percentage at year end — which is where most claims in this sector lose value or become indefensible.
