What Is Line 10100 (Or 101) On Your Tax Return?

When tax season approaches, being strategically organized and having your income taxes in order keeps you way ahead of the game when it comes to filing your return. A perfect way to stay on top of the game is to have clear comprehension of the terminology used on your return. This especially helps to avoid missing out on any benefits you are entitled to or having to deal with any tax debt issues. A fundamental section of your tax return to complete accurately is Line 10100 (formerly specified as 101), which deals with your employment income.

Let’s take a look at the details to help you navigate your way around the form.

Employment Income


Employment income qualifies as any earnings an individual has accumulated from:

  • Salaries
  • Wages
  • Honorariums
  • Bonuses
  • Tips (only those that would appear on a T4)
  • Commissions

What do we mean by Tax Lines? 

Tax lines refer to a filing system which the government and the Canada Revenue Agency (CRA) use on tax reporting forms. Every line on your form represents a different aspect of your tax return, and all  lines are now 5 numbers long.

 

What does 10100 represent on your Tax Return?

Formerly regarded as Line 101 (until 2019) this line is one of the few lines that almost  every Canadian taxpayer must pay attention to and fill out correctly on their return, as it is how Canada Revenue Agency can understand and determine how much employment income each person is declaring.

 

Why is it important to file taxes even if you have no income?

If you work for at least one conventional business, Line 10100 will be displayed as “Box 14” on a T4 tax slip which you receive from your employer(s). The total number of T4 slips you receive for a tax year makes up Line 10100 on your federal tax return, meaning income accrued through multiple employers must be declared individually.

 

Where Can You Find Line 10100 On Your Tax Return?

When you view a completed federal tax return dated 2019 or later, Line 10100 is the first line located under “Step 2 – Total Income”, which should be on Page 3 of your T1 – Income Tax and Benefit Return (also known as a T1 General Form).

Forms can be found online through tax filing software or by simply downloading it through the CRA MyAccount app. However, depending on the tax software you are using, the line could appear under another section.

Important Tax Return Line changes taxpayers should bear in mind


In recent years, the CRA has gradually altered many tax lines in Canada from 3 or 4 numbers to a 5-digit code in order to create a more efficient way of tax reporting. Below we have detailed some of the most significant tax lines you should note changes of:

Tax Line 10100 vs. Tax Line 10400 vs. Tax Line 15000


When managing your federal and provincial/territorial taxes at the same time a lot of uncertainties may arise. To simplify things we have noted 3 particular tax lines that can be easily confused:

Line 10100

This line refers only to employment income, which is anything that appears on a T4 tax slip in box 14.

 

Line 10400

Line 10400 refers to less-traditional income that must be reported. This includes royalties, health benefits and payments received from overseas. These incomes should be declared on Line 10400 of the federal tax return and are not to be declared on a T4 slip.

 

Line 15000

Line 15000 includes all income, including income from employment, investments, interest, taxable gains, RRSPs and all other sources.

Income Sources Reported On Line 10400


There are certain main income types that should not be declared on Line 10100 of your federal or provincial/territorial taxes. These incomes must be put on Line 10400 (Other Employment Income), which is exclusively on your federal tax return:

Clergy Housing Allowance

Any regular payments which clergy members receive from the government to fund housing or utilities.

Sales Tax Rebates

Certain provinces and territories require you to report sales tax credits, like GST and HST as taxable income.

Veteran Benefits

Health, disability, financial and death benefits for Canadian forces members past or present. Veterans families are shown on Box 127 of a T4A slip.

Net Research Grants

An organized payment plan for professionals to cover costs related to government-approved research projects such as travel, assistance, and any equipment.

Wage-Loss Replacement Plans (WLRP)

An employer-employee arrangement that provides temporary payments to employees who lose income for different reasons.

Royalties

Business or trade income made when companies are using a licensed property or asset that you own for profit (for example artists or musicians).

Non-Canadian Employment Income

Income earned annually from foreign employers (all currencies must be reported in Canadian Dollars/CAD).

Medical Premium Benefits

Paying a premium to be included in an employee health plan, means participants can claim  payments as medical expenses on their taxes.

Taxpayers must report profits, losses and contributions made through any company investment plans, known as trust accounts.

Premiums of Group Term Life Insurance Plan

This initiative pays out in the case of the death or disability of current/former workers but is taxable only to the employer.
