Sidestep costly Line 15000 tax return errors with our expert guidance and clear advice.
Line 15000 (previously Line 150) represents your total income on your Canadian tax return. This line combines all your income sources for the year, including employment income, self-employment earnings, rental income, and investment returns. Getting this number right matters – mistakes can trigger CRA reviews or leave money on the table.
As a Calgary-based accounting firm, we regularly help clients correct Line 15000 errors before they cause problems. Here are the most common mistakes we see and how you can avoid them.
1. Missing Income Slips
The most frequent error occurs when taxpayers forget to include all their income slips. The CRA receives copies of your T4s, T5s, and other income documents directly from employers and financial institutions. They will flag any missing amounts.
To avoid this:
- Create a checklist of expected tax slips based on your income sources
- Compare against last year’s return to spot potential missing items
- Check your CRA My Account for slips you might have missed
- Wait until late March to file to ensure you have all documents
2. Incorrect Reporting of Self-Employment Income
Self-employed individuals often make mistakes calculating their business income for Line 15000. Some common errors include:
- Mixing personal and business expenses
- Missing eligible deductions
- Incorrect reporting of GST/HST amounts
- Poor record-keeping throughout the year
If you’re self-employed in Calgary, our tax specialists can help you accurately report your business income and maximize legitimate deductions.
3. Investment Income Reporting Errors
Investment income can be tricky to report correctly. People often:
- Forget to include foreign investment income
- Misreport capital gains and losses
- Incorrectly calculate dividend tax credits
- Overlook reinvested distributions from mutual funds
Keep detailed investment records and consider working with a tax professional if you have complex investment income.
4. Rental Income Miscalculations
Calgary property owners who rent out space need to report this income on Line 15000. Common mistakes include:
- Not reporting rental income from short-term rentals
- Claiming ineligible expenses
- Incorrect allocation of expenses for partially rented properties
- Missing documentation for repairs and maintenance
5. Pension and Benefits Reporting
Retirees and benefit recipients sometimes struggle with:
- Missing CPP or OAS payments in their calculations
- Incorrect reporting of foreign pensions
- Overlooking taxable benefits
- Wrong treatment of lump-sum payments
Tips for Accurate Line 15000 Reporting
Follow these practices to get your total income right:
Keep Organized Records
Create a system to track all income sources throughout the year. Save digital copies of tax slips and important documents.

Review Previous Returns
Compare current year income sources with past returns to spot potential oversights.
