If your BC corporation has a December 31 year-end, the decisions you make in the next eight weeks will shape your corporate and personal tax bill for the year — and most of them cannot be made after the calendar turns. Year-end tax planning is not aggressive avoidance; it is the disciplined timing of income, deductions, and owner compensation so you do not pay a dollar more than you owe, and so cash leaves the business in the most efficient order. For an established BC company that has weathered the pandemic, this is the most valuable financial exercise of the fourth quarter.
Let me walk through the moves that matter, with the BC and federal rates that apply in 2021, and a worked example tying them together.
Start with the rate environment you are planning into
A Canadian-controlled private corporation (CCPC) earning active business income in BC pays a combined small-business rate of about 11% on the first $500,000 of active income — that is the federal 9% net rate plus BC's 2% provincial small-business rate. Income above the $500,000 small-business limit, or income that does not qualify, is taxed at the BC general combined rate of roughly 27% (15% federal plus 12% provincial).
That gap — 11% versus 27% — is the engine behind a great deal of year-end planning. Keeping qualifying active income within the small-business limit, and not inadvertently grinding that limit through passive investment income, is worth real money.
Salary versus dividends: the owner's central decision
The classic owner question is how to pay yourself: salary, dividends, or a mix. There is no universal answer because it depends on your personal marginal rate, your need for RRSP room and CPP contributions, and the corporation's income level. But the principles for 2021 are stable:
- Salary is deductible to the corporation, creates RRSP contribution room, requires CPP contributions, and is taxed at your personal rate. It must be reasonable for services rendered.
- Dividends are not deductible to the corporation (they are paid from after-tax profits), do not create RRSP room or CPP, and are taxed more lightly in your hands because of the dividend tax credit. The integration system is designed so the combined corporate-plus-personal tax is roughly neutral, but timing and bracket effects make the mix matter.
A common, sound approach for owner-managers is enough salary to maximize RRSP room and desired CPP, with the balance taken as dividends — but the right split is genuinely specific to your numbers. Decide and execute before December 31, because salary must be paid (or properly accrued) and dividends declared within the year to count.
Time your capital purchases
If you are planning to buy equipment, vehicles, or technology in the near future, the timing relative to year-end affects your deduction. Capital cost allowance (CCA) — the tax depreciation you claim — generally only begins once an asset is available for use. Buying and putting an asset into service before December 31 can pull a deduction into the current year rather than the next.
Be aware of the half-year rule, which limits your first-year CCA on most additions to half the normal rate. Enhanced first-year write-offs available in this period can change the calculus on certain assets, so model the specific asset before you buy. The point is simple: a purchase you were going to make anyway may be worth accelerating by a few weeks to capture the deduction sooner — but never buy something you do not need just for a deduction, because you are spending a dollar to save a fraction of it.
Accrue bonuses correctly
A corporation can declare a bonus to an owner-manager or employee before year-end, deduct it in the current year, and defer paying it — and the tax on it in the recipient's hands — into the following year, provided it is paid within 180 days of the corporation's year-end. This is a legitimate, well-established tool to deduct in 2021 while shifting the personal income recognition into 2022. It only works if the bonus is genuinely declared and recorded before year-end and actually paid within the 180-day window.
A worked example: Sunova Trades Inc.
Consider a fictional BC contracting company with a December 31 year-end. Before any year-end planning, it projects $560,000 of active business income for 2021. The owner takes a modest salary and has not yet decided on additional compensation.
Scenario A — do nothing. All $560,000 is taxed at the corporate level. The first $500,000 is taxed at roughly 11% (≈ $55,000), and the $60,000 above the small-business limit is taxed at roughly 27% (≈ $16,200), for corporate tax of about $71,200.
Scenario B — declare a $60,000 owner bonus before December 31. The bonus is deductible, pulling taxable income down to exactly the $500,000 small-business limit. Corporate tax becomes roughly 11% on $500,000 ≈ $55,000 — a corporate saving of about $16,200. The $60,000 bonus is paid within 180 days and taxed in the owner's hands in 2022 at their personal rate. The owner has effectively moved $60,000 out of the 27% bracket and into personal income they were going to draw anyway, while deferring the personal tax by a year.
The lesson is not that bonuses are always right — it is that the marginal dollar above the small-business limit costs more than two and a half times the dollar below it, and year-end is your one chance each year to manage which side of that line your income falls on.
Do not let passive income quietly grind your small-business rate
There is a trap that catches profitable BC corporations that have accumulated investments inside the company. If your corporation (together with any associated corporations) earns more than $50,000 of passive investment income in a year, your $500,000 small-business limit begins to grind down, and it is eliminated entirely once passive income reaches $150,000. The effect is that active income you expected to be taxed at roughly 11% gets pushed into the roughly 27% general rate.
This matters at year-end because some of the levers are timing-sensitive. If you are near the $50,000 passive threshold, deferring the realization of a capital gain or interest into the new year, or rebalancing how investments are held, can preserve your small-business rate on a large block of active income. The arithmetic is stark: losing even part of the small-business limit can cost more in extra corporate tax than the passive income itself generated. Any BC corporation holding meaningful investments should check its passive-income figure before December 31, because this is one of the few year-end items where a small amount of planning protects a disproportionately large amount of tax.
Clean up shareholder loans before they bite
One more item that is easy to defer and expensive to ignore: shareholder loan balances. If you have drawn money from the corporation during the year that is recorded as a shareholder loan, those amounts generally must be repaid within one year of the corporation's year-end, or the full balance can be added to your personal income — a harsh result. Year-end is the moment to review the shareholder loan account, decide whether to repay it, convert it to salary or dividends, or document it properly with interest. Sorting this out in December, as part of the salary/dividend decision, is far cheaper than discovering an income inclusion when the return is prepared months later.
A pre-December 31 checklist
- Project full-year active business income and see whether you are near or above the $500,000 small-business limit.
- Check passive investment income, which can grind the small-business limit if it exceeds $50,000.
- Decide your salary/dividend mix and execute it within the year.
- Accelerate planned, genuinely needed capital purchases so assets are available for use before year-end.
- Consider an owner bonus to manage income at the small-business line, payable within 180 days.
- Clean up shareholder loan balances and confirm GST/PST and payroll remittances are current.
Key takeaways
- In BC for 2021, active income up to $500,000 is taxed around 11%; income above that runs near 27% — a gap worth managing.
- Decide and execute your salary-versus-dividend mix before December 31; both have to occur within the year to count.
- Time capital purchases so assets are available for use before year-end, mindful of the half-year rule.
- A bonus declared before year-end and paid within 180 days deducts in 2021 while deferring personal tax to 2022.
- Never spend a dollar purely to save a fraction of it — plan around purchases you were already going to make.
Good year-end planning is not about paying less than you owe; it is about never paying more, and about choosing the order in which cash leaves the company.
