Retained Earnings: What to Do With Surplus Cash

When a corporation earns more profit than its owner needs to withdraw, the surplus accumulates as retained earnings. For a successful business, this is a good problem, but it is still a problem that rewards attention. Left as idle cash, retained earnings lose value to inflation and sit exposed to business risk. Invested or deployed thoughtfully, they can defer tax, build retirement capital, protect the business, or fund an eventual exit. The right choice is not universal; it depends on how much you spend, what you plan for the business, and how the tax rules treat money inside your company.

This article is for incorporated owners and professionals in Ottawa and across Ontario who are watching cash build up in their corporation and want to use it well. It lays out the main options and the trade-offs, not a prescription, which depends on your numbers and should be confirmed with your accountant.

What retained earnings actually are

Retained earnings are after-tax corporate profit that has been kept in the company rather than paid out to you. The corporation has already paid tax on this income at the corporate level; what remains is the surplus available for other uses. Because you have not yet drawn it out personally, you have not yet paid personal tax on it. That deferral is the heart of why incorporation can be valuable, and it is also why what you do with retained earnings matters so much.

Option one: reinvest in the business

The first question is always whether the business itself can use the capital productively: new equipment, additional staff, a location, inventory, or a growth initiative. If the business can earn a strong return on reinvested profit, that is often the most natural home for surplus, because it compounds the value of the enterprise you already own and understand. The caution is discipline. Reinvesting because capital is available, rather than because the opportunity is genuine, destroys value. Surplus should fund real opportunities, not fill space.

Option two: invest in a portfolio inside the corporation

Profit the business cannot usefully reinvest can be invested in a portfolio held by the corporation. This preserves the deferral, since the money has not left the company, and lets surplus grow in markets rather than sit in cash. Our note on corporate investment accounts in Canada covers how this works.

The trade-off is the passive income rules. Once a CCPC earns more than $50,000 of passive investment income in a year, its access to the small business rate begins to grind down, ending at $150,000 of passive income. Corporate investing therefore needs to be tax-aware: favouring investments that defer or reduce annual investment income, timing capital gains, and watching the threshold. Mutual funds and other market investments are not guaranteed, their values change, and past performance may not repeat, so the portfolio should match the corporation’s risk tolerance and timeline.

Option three: move surplus to a holding company

A holding company sits above the operating company and can receive surplus as tax-deferred intercorporate dividends. Owners use a holdco to protect retained earnings from operating risk, to accumulate investments outside the active business, and to help manage both the passive income rules and the purification needed to keep shares eligible for the lifetime capital gains exemption. A holdco adds filings and cost, so it suits owners with meaningful surplus rather than a newer company.

Option four: fund your own retirement

Surplus does not only serve the business; it can serve you. Drawing a reasonable salary builds RRSP room and can support an individual pension plan for older, higher-earning owners, while dividends can fund spending and personal investing. Moving some surplus into personal registered accounts shifts growth into tax-sheltered vehicles and diversifies your wealth away from a single company. Coordinating corporate surplus with your personal retirement income as a business owner is one of the most valuable uses of retained earnings.

Option five: corporate-owned insurance

For some owners, directing surplus to corporate-owned life insurance serves several goals at once: tax-sheltered growth inside the policy, a tax-free death benefit to the corporation, and a credit to the capital dividend account that can later allow tax-free capital dividends to shareholders. Insurance is offered through GP Capital Insurance Agency Ltd. and is sized to the plan. It is not right for everyone, and it trades flexibility for long-term efficiency, so it belongs in a considered plan rather than as a default.

Option six: reduce debt

Using surplus to repay corporate debt is unglamorous but often sound, especially when borrowing costs are high relative to what the surplus could safely earn. Reducing leverage lowers risk and frees future cash flow. The decision is a comparison: the certain saving from retiring debt against the uncertain return from investing, judged against your tolerance for risk.

Comparing the options

The table below is a general comparison, not advice for your situation. The best choice depends on your spending, your exit plans, and the tax rules in force.

Use of surplus	Main benefit	Main trade-off
Reinvest in the business	Compounds a business you know	Only if the opportunity is genuine
Invest in a corporate portfolio	Preserves deferral, grows surplus	Passive income rules can erode the small business rate
Move to a holding company	Protects surplus, aids purification	Added cost and complexity
Fund retirement personally	Diversifies and shelters growth	Triggers personal tax on withdrawal
Corporate-owned insurance	Tax-sheltered growth, estate efficiency	Long-term commitment, less flexible
Reduce debt	Certain, lowers risk	Forgoes potential investment return

Most owners use a blend, revisited as the business and their life change.

Keeping an eye on the exit

Retained earnings and your eventual exit are linked. A company heavy with surplus cash and investments may fail the asset-use tests for the lifetime capital gains exemption, requiring purification well before a sale. Decisions about surplus made casually in the growth years can either preserve or quietly forfeit that later advantage. This is why the ordinary question of what to do with this year’s surplus is best answered with one eye on how you will eventually leave the business.

Avoiding the idle-cash trap

The most common mistake is not choosing the wrong option; it is making no choice at all and letting surplus pile up in a corporate chequing account. Idle cash earns little, loses value to inflation, and, if held in the operating company, sits exposed to business creditors and can count against the asset-use tests for the lifetime capital gains exemption. None of this announces itself. The balance simply grows, the deferral advantage goes unused, and the eventual sale becomes more complicated than it needed to be. Treating surplus as a standing agenda item, rather than something to deal with eventually, is what separates owners who compound their retained earnings from those who merely accumulate them. The goal is not to act hastily but to decide deliberately, each year, where this year’s surplus should go.

Next step

What to do with retained earnings is rarely a single decision; it is an annual discipline that balances the business, your retirement, the tax rules, and your exit. The owners who use surplus best are those who review it each year with coordinated advice rather than letting it drift into a bank account. Our business-owner planning and investment management services are built for this.
