Tax Planning Strategies Every Canadian Business Owner Should Know Before Year-End

Every year I sit down with my clients about 90 days before their fiscal year-end. The conversation is always the same: "How do we keep more of what we've earned?" The answer isn't aggressive loopholes. It's disciplined planning with the tools the tax code already gives you.

Review Your Salary vs. Dividend Mix

If you own a corporation, how you pay yourself matters. Salary is deductible to the company (reduces corporate tax) but creates personal income tax and CPP obligations. Dividends are not deductible (paid from after-tax corporate income) but are taxed at lower personal rates through the dividend tax credit.

The optimal mix depends on your personal situation. Do you need RRSP room? (Only salary creates it.) Are you maximizing CPP contributions? (Only salary counts.) What's your personal tax bracket? I've seen clients save $8K to $15K per year just by optimizing this split instead of taking all salary or all dividends.

According to the CRA, the small business deduction saves qualifying corporations $50K to $73K per year in federal taxes on the first $500K of active income. Make sure you're taking full advantage.

Accelerate Expenses, Defer Revenue

If your year-end is December 31 and you're having a profitable year, consider pulling expenses into this year and pushing revenue into next year where legally possible.

Buy that equipment in December instead of January. Pay January's rent in December (prepay). Stock up on supplies you'll use in Q1. These are all legitimate ways to reduce this year's taxable income.

On the revenue side, if you can delay invoicing a December project until January without affecting the client relationship, that income shifts to next year. Don't play games here, but timing within a few days is standard practice.

Capital Cost Allowance

If you need equipment, vehicles, or technology, buying before year-end lets you claim CCA (depreciation) in the current year. The Accelerated Investment Incentive Program allows most businesses to claim up to 1.5 times the normal first-year CCA deduction.

For a $50K vehicle purchased before year-end, the first-year CCA deduction could be $22,500 instead of $15,000 under the accelerated rules. That's a real tax reduction, and you were going to buy the vehicle anyway.

SR&ED Tax Credits

If your business does any research and development work (and the definition is broader than most people think), you may qualify for Scientific Research and Experimental Development credits. This is one of the most generous tax incentives in Canada. Qualifying Canadian-Controlled Private Corporations can receive a 35% refundable investment tax credit on the first $3M of eligible expenditures.

I've had clients recover $30K to $100K in SR&ED credits they didn't know they were eligible for. If you're developing new products, processes, or technology, talk to a specialist before year-end.

Write Off Bad Debts

Check your AR aging. Any receivables that are genuinely uncollectable should be written off before year-end. A $15K bad debt write-off at a 12% corporate tax rate saves you $1,800 in taxes. It also cleans up your balance sheet and gives you a more accurate picture of your financial position.

Document your collection efforts before writing anything off. The CRA may ask you to prove the debt was genuinely uncollectable.

Maximize Deductible Expenses

Review your expense categories for anything you're missing. Common ones that get overlooked: home office expenses (if you work from home), automobile expenses (log your business kilometres), professional development, industry association fees, and business insurance premiums paid in advance.

Plan Your Personal Draws

If you've been pulling money out of the company throughout the year as shareholder draws, make sure those are properly documented as salary, dividends, or shareholder loan repayments before year-end. Unclassified shareholder draws create tax headaches. Your accountant needs to know the intended classification before they prepare the corporate return.

What to Do 90 Days Before Year-End

1. Pull your year-to-date P&L. Estimate where you'll land on December 31 (or your fiscal year-end). This is your baseline.
2. Model salary vs. dividend scenarios. What combination minimizes your total tax bill (corporate + personal)?
3. List planned purchases. Anything you need in Q1 of next year that could be purchased before year-end?
4. Review AR for bad debts. Anything over 180 days that you'll never collect?
5. Talk to your accountant. Not in March during tax season. Now, when there's still time to act.

The Bottom Line

Tax planning isn't about gaming the system. It's about using the rules that already exist to keep more of what you've earned. The difference between planning and not planning is often $10K to $30K for a business doing $500K to $2M in revenue.
