See what the retained earnings sitting in your corporation are likely costing you in tax every year — and the opportunity you're leaving on the table by letting that cash sit.
Estimates only. Use rough numbers — precision isn't the point of this tool.
What this cash is likely costing you in tax each year — versus growing it in a tax-sheltered structure.
This tool gives you a directional estimate. Your actual situation — what you hold, how it's taxed, your active income, your timeline — changes the picture.

Book Your Strategy SessionEducational tool only — not tax, legal, or financial advice. This calculator produces directional estimates using simplified, top-marginal 2026 corporate tax assumptions and does not reflect your specific facts. It assumes your corporate investment income is fully taxable (interest, dividends, rents). If your returns are mostly capital gains, only the taxable half is taxed each year, so your real drag may be lower. A portion of corporate tax on investment income is refundable when you pay taxable dividends — timing and amount vary. The "tax-sheltered structure" scenario assumes a properly designed, exempt corporate-owned permanent insurance policy; insurance carries its own costs and rules, and growth is tax-sheltered only within exempt-policy limits. The $50,000 passive-income threshold grinds the federal small business deduction ($5 of business limit per $1 over $50k, eliminated at $150k); Ontario and New Brunswick keep their provincial small business deduction.
