What the OIDMTC actually pays for
The Ontario Interactive Digital Media Tax Credit is a refundable credit, administered by Ontario Creates alongside the CRA, on the eligible Ontario labour that builds a qualifying product. For a product you develop and sell or license yourself, the credit runs at 40% of eligible labour, and eligible marketing and distribution spending also qualifies, capped at $100,000 per product. For a product developed under a fee-for-service agreement, the rate is 35% on eligible labour, with no marketing component. Eligible labour reaches both your Ontario employees and arm's-length Ontario-resident individual contractors — one reason contractor residency belongs in the ledger from day one. Program criteria also include the 80/25 rule: broadly, at least 80% of the labour to develop the product must be paid to Ontario-based individuals, and at least 25% must be wages of your own employees, so a studio built entirely on offshore outsourcing plans itself out of the credit. Criteria move with provincial budgets, so we confirm the current published rules before a dollar of refund enters your forecast.
Own product or work-for-hire: the rate follows the deal
| Question | Own product | Fee-for-service product |
|---|---|---|
| Who sells it to the public | You do | The purchaser does |
| Credit rate on eligible Ontario labour | 40% | 35% |
| Marketing and distribution costs | Eligible, up to $100,000 per product | Not eligible |
| Typical deal shape | Self-published, or advance against royalties | Work-for-hire development agreement |
The classification is decided by the contract, which means it is decided before the contract is signed — or it should be. An advance-against-royalties deal where you keep the IP is a different credit than a work-for-hire agreement paying the same dollars, and the gap compounds over a multi-year build. Timing has its own geometry: a claim gathers eligible labour from a window of roughly three years before the product is completed, so a long build does not lose its early payroll — but only if the records from those early years were kept to claim standard. We read the credit consequences into the deal memo, not out of the wreckage.
SR&ED and the OIDMTC share a payroll — split it on purpose
SR&ED pays for experimental development: work attacking genuine technological uncertainty, which in a studio usually means engine and tools work, novel netcode, procedural systems — not level design, art production or balancing. A Canadian-controlled private corporation earns the enhanced federal credit at a refundable 35% on qualified expenditures, which is why CCPC status is protected at incorporation and after. The catch is that the two programs meet in the middle of your payroll: the same labour dollar cannot be claimed under both, and assistance under one program reduces the base of the other. Planned, that is an allocation exercise — this programmer's uncertainty-driven engine work to SR&ED, that team's production labour to the OIDMTC, tracked per person and per task as the year runs. Discovered at filing, it is a compromise in which both claims shrink. Ontario layers its own research credits on top of the federal claim, which sweetens the SR&ED side of the line without changing the logic: decide the split while the work happens. Mapping that split — by project, by person, with the time tracking to hold it up — is the core of the studio engagement inside Tax Planning & Advisory.
The refund is taxable fuel — budget it that way
Credit refunds are government assistance: they reduce expense pools or enter income, so a refund never lands whole. Planning treats it as pre-tax fuel — real, large, worth every hour of documentation, but budgeted net. The corporate rate side helps: with the small business deduction, roughly 12.2% applies to the first $500,000 of active income in Ontario, so a profitable studio keeps most of what the credits return. The remaining questions are timing ones. A year-end can be chosen to suit the certificate cycle rather than inherited from the incorporation date. Instalments deserve a fresh look in any year a refund distorts income. And founder pay wants planning against the studio's shape: lean salaries through development years when every dollar is burn, a deliberate salary-dividend mix once a launch year lands profit at the corporate rate. Each of these gets a decision on the calendar, not a scramble in April; the cash-flow side of waiting for refunds belongs to the CFO conversation.
