Top 10 Bookkeeping & Income Tax Mistakes Ontario Realtors Make
…and How to Avoid Them with Proper Systems & Support
Running a successful real estate business in Ontario requires more than closing deals—it also means staying on top of your finances, tax deadlines, and CRA requirements. Unfortunately, many realtors lose money every year because of avoidable bookkeeping errors and misunderstood tax rules.
Below are the 10 most common mistakes realtors make, along with guidance to keep your business compliant, profitable, and stress-free.
- Not Setting Money Aside for Income Taxes (and CPP)
Because taxes aren’t deducted from commission cheques, many realtors spend first and think about taxes later. This leads to painful April surprises.
Solution: Set aside 25–35% of every commission into a separate tax savings account.
- Treating HST as Income
Realtors often see the full deposit—including HST—and assume it’s all theirs.
Reality: HST is not income; it’s a trust amount owing to CRA.
Solution: Track HST as a liability, not revenue.
- Not Setting the HST Portion Aside
Even if they know HST isn’t theirs, many realtors still spend it.
Solution: Move the 13% HST from each commission into a separate bank account so it’s ready for your return.
- Not Knowing What Expenses Are Legitimately Deductible
Realtors frequently under-claim deductions, meaning they pay more tax than necessary. Commonly missed expenses include:
- Marketing, photography, staging
- Brokerage/desk fees
- Cell phone & internet (business portion)
- Vehicle expenses
- Home office deductions
Solution: Keep clear records and learn which expenses qualify.
- Claiming Expenses That Aren’t Deductible
Some realtors over-claim items such as personal clothing, family travel, or 100% of meals and entertainment.
Solution: Understand CRA rules and document the business purpose for each expense.
- Mixing Business and Personal Accounts
Using one account for everything leads to messy, expensive year-end cleanups and missing deductions.
Solution: Open dedicated business accounts and use them consistently.
- Poor Record-Keeping and Missing Receipts
CRA can deny any deduction you can’t support. Many realtors lose money simply because receipts are lost or incomplete.
Solution: Use an app to photograph receipts immediately. Note who the meeting or purchase was for and why.
- Incorrect Vehicle and Home-Office Claims
Two areas CRA reviews closely:
- Vehicle: No mileage log = no reliable business percentage.
- Home Office: Must meet CRA’s use-of-home-for-business rules.
Solution: Track kilometres carefully and calculate home-office space accurately.
- Missing Filing & Payment Deadlines
Self-employed realtors face:
- Personal tax payment due April 30
- Filing deadline June 15
- Possible quarterly instalments
- HST filing deadlines based on your reporting frequency
Solution: Use a calendar system and automate reminders.
- Choosing the Wrong Structure (or Misusing a PREC)
A Personal Real Estate Corporation can be beneficial—but only when used correctly and at the right income level.
Solution: Consult a tax professional before incorporating or adjusting your compensation strategy.
