A corporation was about to lose its small business rate to passive income. We restructured to protect the deduction.
A corporation with growing investment income was approaching the passive-income threshold that grinds down the small business deduction. We reviewed the investment mix, moved assets into a more efficient structure, and managed the annual passive income below the threshold. The low small business rate on active income was preserved.
Planning has to be in place before the transaction. The salary-versus-dividend mix, the timing of a capital purchase and the choice of year-end all change the outcome, but only prospectively.
Why it bites: Almost every planning opportunity we see missed was available and simply not taken in time; very few are recoverable after year-end.
A CCPC files its T2 within six months of year-end, with the balance due two months after (three where the small business deduction is claimed). The 9% federal small business rate applies to the first $500,000 of active business income.
Why it bites: The filing and payment deadlines differ, and interest runs from the payment date. Filing on time while paying late still costs money.
Every engagement above was priced as a fixed fee agreed before the work started, and paid only once the client had reviewed the result. If any of this looks like your situation, the first step is a free 15-minute call — we will tell you plainly whether there is anything worth doing.
