What is Line 10100? A Comprehensive Guide to Reporting Employment Income on Your Canadian Tax Return

When it comes to filing your Canadian tax return, accurately reporting your income is of utmost importance. And that’s why you’re here! To find out an aspect of it.
Line 10100 is a crucial section on the Canadian tax return where individuals report their employment income, including salaries, wages, commissions, bonuses, tips, gratuities, and honoraria. It not only determines your taxable income but also plays a significant role in assessing your eligibility for various tax credits and benefits.
In this comprehensive guide, we’ll delve into the intricacies of Line 10100, helping you understand its significance and how to report your employment income correctly.
Locating Line 10100 on the Tax Return
To begin, let’s familiarize ourselves with the location of Line 10100 on your tax return. You’ll find this line on the third page of the T1 General Form, under Step 2 – Total Income. To make it even easier for you to identify where to input your employment income, refer to the image below, which highlights Line 10100.

Types of Income Reported on Line 10100

- Salaries and wages: This encompasses your regular earnings from employment, which you receive for the work you perform.
- Commissions: If your income is based on sales or performance, such as in sales roles, the commissions you earn should be reported on Line 10100.
- Bonuses: If you receive additional compensation for meeting or exceeding targets set by your employer, these bonuses are to be included in your employment income.
- Tips and gratuities: For professionals in service industries, tips and gratuities received from clients or customers are considered part of your employment income and should be reported on Line 10100.
- Honoraria: If you receive payments for services rendered, typically without a set fee, such as speaking engagements or writing articles, these honoraria should be included in your employment income.
Your employer usually provides these amounts in box 14 of the T4 slip. It’s essential to ensure that you have received all your T4 slips and that the amounts reported on your tax return match those on your T4s.
Distinguishing Line 10100 from Other Lines
- Line 10400 – Other Employment Income: This line is designated for reporting income that is not found on your T4 slip. Examples include foreign employment income, research grants, and income from a wage-loss replacement plan. Make sure to report such income on Line 10400 rather than Line 10100.
- Line 15000 – Total Income: Line 10100, along with Line 10400 and income from other sources like investments, rental properties, and self-employment, are combined on Line 15000 to calculate your total income for the tax year.
By clearly understanding the distinction between these lines, you can ensure accurate reporting and avoid any potential issues with the Canada Revenue Agency (CRA). Armed with the knowledge of what types of income go on Line 10100, let’s make sure you avoid some common pitfalls.

Now that you know what lies under Line 10100, it becomes very important to avoid some common mistakes.
To ensure a smooth and accurate tax filing process, it’s essential to be aware of common mistakes made when reporting employment income on Line 10100 which are listed below:
1. Missing T4 slips: One of the most common errors is failing to report income from all T4 slips. Ensure that you have received T4 slips from all your employers for the tax year. If any are missing, contact your employer or access your CRA My Account to retrieve them.
2. Incorrect amounts: Another mistake is entering incorrect amounts on Line 10100. Double-check that the amounts you enter match those on your T4 slips to avoid discrepancies.
3. Misclassification of income: Ensure that you report only employment income on Line 10100. Other types of income, such as self-employment income or investment income, should be reported on their respective lines.
Inaccurate reporting can lead to significant consequences, ranging from reassessments and interest charges to the CRA imposing penalties. Moreover, misreporting can impact your eligibility for benefits and credits, such as the Canada Child Benefit or the GST/HST credits. To avoid these issues, take the time to review your tax return carefully and seek assistance if needed.
Tips for Accurate Reporting
Got your head around the common mistakes? Awesome. Here are some tips to keep that report more accurate than ever listed below:
1. Stay organized: Throughout the year, maintain organized records of your employment income and related documents. This includes keeping track of your pay stubs, T4 slips, and any other relevant information. Having a well-organized system will make the tax filing process much smoother.
2. Utilize tax software: Consider using certified tax software that can import your T5 information directly from the CRA. This feature minimizes the chances of manual input errors and ensures that your employment income is accurately reported on Line 10100.
3. Seek professional assistance: If you find yourself in a complex tax situation or are unsure about how to report certain types of income, don’t hesitate to consult with a tax professional. They can provide valuable guidance and ensure that your tax return is filed accurately and in compliance with tax laws.
The Importance of Accurate Reporting
1. Determining taxable income: Your employment income is a significant component of your taxable income. By accurately reporting on Line 10100, you ensure that your taxable income is calculated correctly, which impacts the amount of taxes you owe or the refund you may receive.
2. Eligibility for credits and benefits: Many tax credits and benefits, such as the Canada Workers Benefit or the Canada Child Benefit, are based on your reported income. Inaccurate reporting on Line 10100 can affect your eligibility for these credits and benefits, potentially leading to missed opportunities or the need for adjustments later on.
3. Compliance with tax laws: Accurately reporting your income is a legal obligation. By ensuring that your Line 10100 information is correct, you demonstrate compliance with tax laws and avoid potential penalties or legal consequences.
4. Financial planning and decision-making: Having an accurate representation of your employment income on your tax return provides a clearer picture of your overall financial situation. This information can be valuable when making financial decisions, such as budgeting, saving for retirement, or applying for loans.
