Before you invest company cash, give it a job. Some of it covers next month's payroll. Some belongs to tax instalments or an equipment purchase. Only the amount beyond those commitments can support a longer plan.
A larger bank balance can make an owner feel ready to invest while a late customer payment still leaves the company short. Start with current records and a cash forecast.
Set aside money for bills before you invest
- List payroll, tax, loan payments, supplier bills and committed purchases, including their due dates.
- Keep enough cash for late customer payments, seasonal changes and slower months.
- Set aside money you'll need personally, including the tax on taking it out of the company.
- Compare uses for the amount that remains: business investment, debt repayment, owner pay or longer-term investing.
Compare each choice using the same dates and cash needs. Money invested for years may not be available when a bill comes due. Selling at the wrong time could leave you short.
Include the tax when you take the money out
Leaving profit in a corporation may let you invest more now. But the corporation may pay tax on investment income. You may also pay personal tax when you take the money out. Include both in the comparison. The rules depend on the type of income.
A corporation may get some investment tax back when it pays taxable dividends. Include those refunds as well as the personal tax on the dividends. Leaving either out can give the wrong picture.

Investment income can affect business tax
For a Canadian-controlled private corporation with the full $500,000 federal business limit, the passive-income reduction removes $5 of that limit for each $1 of adjusted aggregate investment income above $50,000. It reaches the full limit at $150,000. Associated companies' amounts are combined, generally using taxation years ending in the preceding calendar year.
For illustration, $80,000 of adjusted aggregate investment income would reduce a full $500,000 limit by $150,000, leaving $350,000 before any other reduction. That's a reduction in income eligible for the small business rate, not a $150,000 tax bill.
This illustration assumes a full-year limit with no allocation, assignment or taxable-capital reduction. An allocated limit changes the calculation. The income measure has specific inclusions and exclusions; portfolio value and total cash received aren't substitutes for it.

The tax cost depends on how much business income qualifies and on federal and provincial rules. Losing part of a limit you would not use may not cost you any tax this year.

A holding company needs a reason
Moving investments into an associated holding company doesn't give the group a fresh $50,000 passive-income threshold. An extra company also brings setup, legal, filing and administration costs.
Compare the intended benefit with those costs and the tax treatment of the proposed transfer. Asset protection depends on the legal structure and facts; a holding company doesn't automatically protect every asset or qualify a future share sale for an exemption.
When keeping the cash available comes first
Keep cash available if you still need to pay taxes, customers may pay late or a purchase is coming up. Loan terms may also limit what you can take out. Paying yourself now can create extra cost if the business needs you to lend the money back later.
Bring your current financial statements, investment records, corporate tax records and personal spending needs. Mention plans to sell or change the business. The review should show what money you could use, when you could use it and what could change the result.
