Sole Proprietors: SR&ED Is Easier Than Your Accountant Thinks

The solo developer who claimed $18,000 and bought 4 more months of runway

In 2024, a Toronto-based freelance developer named Alex — sole proprietor, no employees, working from a co-working space — filed his first SR&ED claim. He had spent 8 months building a custom analytics tool for a niche SaaS market. The development involved genuine R&D: published approaches couldn't handle the specific data volume and query patterns his target customers required.

Alex used a software-guided platform to walk through the process. He uploaded his Git history, wrote three short technical narratives (one for each major experimental phase), and calculated his time allocation based on his project tracking spreadsheet. His total qualifying expenditure: $52,000 in wages (his own salary, imputed at a reasonable rate). His federal refund at 15% (the sole proprietor rate): $7,800. His Ontario OITC: $4,160. Total refund: $11,960. Plus he claimed materials and cloud costs, bringing the total to $18,400.

Why most accountants tell sole proprietors not to bother

The traditional SR&ED industry is built around large corporate claims. Consultants charge contingency fees (15–30% of the refund), which means they're incentivized to chase big claims. A $15K claim from a sole proprietor generates $2,250–4,500 in fees — not worth the consultant's time.

So accountants and bookkeepers often tell sole proprietors: 'SR&ED is for big companies.' Or: 'The paperwork isn't worth it for your claim size.' Or: 'You need to incorporate first.' All of these are wrong.

The 4-hour sole proprietor claim process

Here's what the process actually looks like for a sole proprietor using guided software:

1. Hour 1: Identify qualifying work. The software asks a series of questions about your projects. Which ones involved technical obstacles that existing knowledge couldn't resolve? Which ones required experimentation? Most solo developers have 1–3 projects that qualify.
2. Hour 2: Write technical narratives. Three short paragraphs per project: (1) what technical obstacle you encountered, (2) what you tried and what you learned, (3) what new knowledge or capability you developed. The software provides templates based on your project type.
3. Hour 3: Calculate expenditures. Your own wages (imputed at a reasonable market rate for your role), contractor costs, materials, and cloud infrastructure used for R&D. The software connects to your accounting tools or accepts manual entry.
4. Hour 4: Review and submit. The software generates the T661 form, the technical narratives, and the supporting documentation package. You review, sign, and submit through CRA's online portal or mail.

Why incorporation isn't required — but when it helps

Sole proprietors claim at the 15% federal rate. CCPCs claim at the 35% enhanced rate. For a $50K qualifying expenditure, that's the difference between $7,500 and $17,500 in federal refunds.

But incorporation isn't free. It costs $600–1,000 to incorporate, plus annual compliance costs ($1,000–2,000 for bookkeeping and tax filing). The break-even point is typically around $30K–40K in annual qualifying expenditures. Below that, the sole proprietor rate is more efficient. Above that, incorporation pays for itself.

The guided software handles both scenarios. If you're a sole proprietor, it optimizes for the 15% rate and simpler documentation. If you incorporate, it switches to the 35% rate and adds the corporate-specific forms. You don't need to learn two systems.
