## How It Works

Enter your company profile (corporation type, taxable capital, province) and R&D expenditures. The calculator instantly estimates your:

- **Federal ITC** — 35% enhanced rate (CCPCs, first $3M) + 15% basic rate

- **Provincial Credit** — Rates vary: Ontario 8%, Quebec 14-30%, BC 10%, Alberta 8%, Manitoba/NB/NL/NS/YT 15%

## Key Calculation Rules

- **Expenditure Limit**: $3M for CCPCs, phases out between $10M-$50M taxable capital
- **Proxy Method**: 55% of directly-engaged salaries added as overhead (PPA)
- **Traditional Method**: Claim actual overhead if directly related and incremental
- **Contract Payments**: 80% of SR&ED contract costs are eligible
- **Qualifying Corporation**: Prior-year income ≤ $500K (phases out with capital) for full refundability
