SR&ED Taxable Capital Limit: What a Large Round Does to Credits

How does taxable capital cut the SR&ED limit and the small business deduction?

A Canadian-controlled private corporation (CCPC) loses part of two benefits when its taxable capital employed in Canada for the previous tax year passes set thresholds. Both cuts are straight-line, and both count the capital of associated corporations (section 127; section 125).

The CRA confirms the SR&ED range above for tax years that began on or after December 16, 2024; earlier tax years used a narrower range.

What makes a case not simple:

• Associated companies. A founder's holding company or another controlled company adds its capital to the total and shares both limits.
• The round ends CCPC status. Then the enhanced credit is gone, not just reduced. See losing CCPC status to foreign investors.
• SAFEs and notes. How they count depends on the balance sheet.
• A short tax year. Both limits are prorated.

What to gather: year-end balance sheets for the last two years, the cap table with every SAFE, note, option and warrant, and the T2s and balance sheets of any company that may be associated.

What is taxable capital employed in Canada, and does the money we raised count?

Yes, the money raised counts. Taxable capital starts from the year-end balance sheet: share capital, retained earnings, contributed surplus and other surpluses, plus loans and advances to the corporation, bonds and notes it issued, and other debt outstanding more than 365 days (section 181.2). Any deficit is subtracted.

Share capital counts at the amount raised, whether the cash is still in the bank or already spent; spending lowers taxable capital only through the deficit (below). Cash and government securities do not reduce it. The investment allowance does: shares of, and loans or bonds issued by, other corporations, interests in partnerships, and long-term debt of a financial institution held at year-end. Shares of a subsidiary, such as a US operating company, fall in this list.

Amounts come from the balance sheet presented to shareholders, prepared under generally accepted accounting principles, without consolidation or the equity method (section 181). For a corporation whose permanent establishments are all in Canada, taxable capital employed in Canada is all of its taxable capital (Regulation 8601).

Do SAFEs, convertible notes and preferred shares count before they convert?

Usually yes, because the money is on the balance sheet either way. Preferred shares are share capital. A convertible note is indebtedness represented by a note, which section 181.2 lists. A SAFE is not named in the Act: it counts as equity or surplus if the balance sheet shows it in equity, and as a loan, advance or other debt if it shows it as a liability. Whether a short-term liability that is neither a loan nor a note counts can turn on the classification, so treat a SAFE as unsettled until the year-end statements are final.

A separate question, whether convertible rights count toward control and CCPC status, is answered in losing CCPC status to foreign investors.

Do our accumulated losses lower taxable capital?

Yes. A deficit deducted in shareholders' equity at year-end is subtracted from capital (section 181.2). A startup that raised a large amount and spent much of it on research may have taxable capital well below the total raised. The deficit is the accounting deficit on the balance sheet, not the tax losses carried forward on the T2.

Which year's taxable capital cuts which year's limits?

Each year's limits use the previous tax year's taxable capital. For a stand-alone corporation, the SR&ED limit, the qualifying income limit and the business limit all look at its taxable capital for the immediately preceding tax year (section 127; section 127.1; section 125). For an associated group, each company's capital is taken for its last tax year that ended in the previous calendar year. A corporation that was associated last year but is not this year uses this year's capital for the business limit (subsection 125(5.1)).

So a round closed this year lowers next year's limits, not this year's. A tax year shorter than 51 weeks has its SR&ED limit and business limit prorated by days over 365. For year-end choices, see choosing or changing a year-end.

Does closing the round before or after year-end change which year is hit?

It can. The test reads the balance sheet at the end of the previous tax year, so money received on or before that year-end counts for the following year's limits, and money received after it counts one year later. A note funded before year-end counts in that year-end balance sheet even if the priced round closes later; a SAFE usually does too, depending on how it is classified. Closing dates are usually set by the investors' terms; treat the tax effect as one input, and confirm both year-ends' balance sheets before relying on it.

How does the SR&ED expenditure limit shrink as taxable capital grows?

The expenditure limit is $6 million × ($75 million − prior-year taxable capital) ÷ ($75 million − $15 million), never more than $6 million and never below nil (subsection 127(10.2)). Qualified spending up to the limit earns the enhanced 35% credit; spending above it earns the basic 15% credit.

The revenue election can flip this. A CCPC that is not associated with any other corporation throughout the year may elect to compute its limit on the same range applied to average annual revenue over the three preceding fiscal years, from $15 million to $75 million, instead of taxable capital (subsections 127(10.31) and 127(10.6)). Associated CCPCs must all elect together (subsection 127(10.32)). For a startup with large capital and little revenue, the election can restore the full limit. The election is made on a prescribed form; the CRA policy says that form and an allocation schedule are to be published in the fall, so check the current form before filing. With fewer than three preceding fiscal years, the average uses the years there are, and a fiscal year under 51 weeks is annualized (subsection 127(10.64)).

What credit do we get above the limit, and is any of it still refundable?

Spending above the limit earns the basic 15% credit. Whether any of it comes back in cash depends on whether the CCPC is a qualifying corporation: its prior-year taxable income, with associated companies', must not exceed a qualifying income limit of $500,000 reduced on the same $15 million to $75 million taxable capital range (section 127.1). The CRA policy states: "Where a CCPC's income limit is reduced to zero, it is not a qualifying corporation."

A loss-making startup with prior-year taxable capital below $75 million usually stays a qualifying corporation, because its nil taxable income is under a reduced but positive limit. At $75 million or more, the CRA treats the company as not qualifying, so the basic credit can only reduce tax; unused credits carry back 3 tax years and forward 20 (CRA).

How does the small business deduction shrink, and does it matter before we have profit?

The business limit is $500,000 × ($50 million − prior-year taxable capital) ÷ ($50 million − $10 million), never below nil (subsection 125(5.1)). The T2 guide confirms the business limit reaches nil at $50 million. When the passive-income reduction is larger, that one applies instead; see holding and investment corporations.

A startup with no taxable income loses nothing from this cut that year, because the deduction only lowers tax on active business income. It matters once the company is profitable and its capital is still above $10 million. For rates and the deduction in general, see how corporations are taxed.

Do our investors' or founders' other companies count toward the total?

Only companies associated with yours. Corporations are associated when one controls the other, when the same person or group controls both or through certain links between related people who each control one of them (section 256). A founder's holding company that controls the startup, or a second company the same founder controls, is associated. A minority venture fund that does not control the startup usually is not, but a group of shareholders that controls both companies can be. For this test, rights to acquire shares, such as options, warrants, SAFEs and convertible notes, are treated as exercised (subsection 256(1.4)).

Associated CCPCs add their taxable capital together for both cuts, and share the limits on Schedules 23 and 49 (CRA). If they do not file the allocation agreement within 30 days of a CRA request, the CRA allocates the limit itself (subsection 127(10.4)).

Which T2 schedules show the calculation?

Example

All figures are illustrative and in Canadian dollars. Each company has a December year-end, its permanent establishments are all in Canada, and it is a stand-alone CCPC.

Series A closed in March

• Year 1 (round year): The company raises C$25 million in March. Its prior year-end taxable capital was C$4 million, so the full C$6 million SR&ED limit applies this year.
• Year 2: Year 1 closes with C$29 million of share capital and a C$7 million deficit, so taxable capital is C$22 million. The SR&ED limit becomes C$6 million × (75 − 22) ÷ 60 = C$5.3 million. The business limit becomes C$500,000 × (50 − 22) ÷ 40 = C$350,000, which costs nothing while the company has no profit. With nil prior-year taxable income, it is still a qualifying corporation, so basic credits on spending above C$5.3 million are partly refundable.

Series B pushes capital past the top of the range

Prior year-end taxable capital is C$90 million after a C$80 million Series B, and average revenue is C$2 million. The company spends C$3 million on current SR&ED work.

• Without the revenue election: the limit is nil, and the CRA treats the company as not a qualifying corporation. It earns C$450,000 (15% of C$3 million) that can only reduce tax or be carried back or forward. Before the round, the same spending earned C$1.05 million (35%), fully refundable.
• With the revenue election: average revenue is under C$15 million, so the full C$6 million limit applies and the C$1.05 million credit on current spending is fully refundable.

Closing on December 20 or January 5

A C$30 million round funded on December 20 sits in that year-end balance sheet, takes taxable capital above C$15 million and lowers the next year's limits. Funded on January 5, it first appears at the following year-end, so the cut starts one year later.

• SAFEs or notes sit on the year-end balance sheet, or you are weighing the revenue election: the numbers depend on classification and a new form; get corporate tax help.
• You need to file the claim or want to know when the refund arrives: see claiming SR&ED on your corporate return.
• Grants or IRAP funding reduce the spending: see IRAP and other government funding.
• The company earns investment income: the passive-income limit may cut the small business deduction instead; see holding and investment corporations.
