Understanding taxes can feel like reading another language. Each form has rows of numbers. Many look similar, but they do not mean the same thing. One line, however, stands out. Line 15000 plays a major role in your tax return. It does more than list a number. It shows the full amount of money you earned in a year before any deductions, claims, or credits.
This line gives the Canada Revenue Agency (CRA) the full picture of your financial life. It also helps banks, schools, landlords, and benefit offices decide how much support you should get. If you need a loan, apply for rent relief, or request aid for education, many forms will ask for the number from Line 15000.
This line was known as Line 150 until a few years ago. The CRA updated its format and turned many old numbers into five-digit versions. That is why Line 150 is now called Line 15000. But the meaning is the same. It still gives your total income before anything else gets subtracted.
Knowing what goes into this number helps you in many ways. You can answer income questions with confidence. You can avoid filing errors. You can track how your money moves through the system. This article explains everything you need to know about Line 15000 in plain, easy English.
What Line 15000 Means on Your Tax Return
Line 15000 shows your total income for the year. This means every dollar you earned that counts as taxable income. It includes income from jobs, self-work, retirement, government support, and even certain types of investments. It does not reduce or adjust anything yet. That happens later on the return.
Think of Line 15000 as the starting point. It stands near the top of your tax form. From there, the CRA looks at deductions and credits to lower what you owe. But before that happens, they use this line to get your gross income.
This number gives others a look at how much money you brought in over the year. That is why schools, lenders, and aid programs may ask for it. It gives them a clear, honest view of your total earnings, no matter where the money came from.
Many people see this number and think it shows what they take home. It does not. Your paycheck after tax looks smaller because that is your net pay. Line 15000 lists everything before tax. That is why it often appears higher than expected.
Where Can You Find Line 15000?
You can see this line in a few official places. First, look at your personal income tax return, also called the T1 General. The number sits in the first pages under the section marked “Total Income.” You will see it near the top before deductions and credits appear.
You can also find it in your Notice of Assessment. This is the summary the CRA sends you after they review your return. The number will be listed in bold along with your other totals. If you created a CRA My Account, you can also view it online by checking your tax records.
Another way to track your total income is to add up your tax slips. These slips include T4s from employers, T5s from banks, and T4As for other types of income. Each one shows part of your yearly total. The final sum becomes your Line 15000 amount.
If you forget where to look, you can ask your accountant or use certified tax software. Most digital tax tools show the line clearly during the review stage. Always double-check the number before you submit your return.
Where to Find Line 15000 on Your T4 Slip
Many people try to find Line 15000 directly on their T4 slip. That number does not appear on the slip. A T4 shows your earnings from a single job. It lists your employment income in Box 14. This is only one part of your total income.
Line 15000 is the full income from all sources. You must add Box 14 from all T4 slips you receive. You also need to include other slips like T5s or T4As. These show interest, dividends, and other types of income. The CRA uses all of these to calculate Line 15000 on your return.
So, if you are looking at your T4 and cannot find Line 15000, check your T1 General tax return instead. That is where the full amount appears.
How to Calculate Line 15000 from Your T4
You can calculate Line 15000 by adding all of your taxable income slips together. Start with your T4 slips. Look at Box 14. This shows your total employment income from each job. If you worked more than one job, add up all the Box 14 values.
Then check your other slips. If you received a T4A, T5, or a pension slip, include those amounts. You must also include income from self-employment or rental activity. These amounts usually come from your own records or business forms.
When you add all your taxable income together, you get the number for Line 15000. This is your total income before any deductions or credits.
Sarah worked two jobs in 2023. Her first T4 showed $28,000 (Box 14), and the second showed $15,000. She also earned $2,000 in freelance income and $500 in interest from a savings account.Her Line 15000 total would be:
$28,000 + $15,000 + $2,000 + $500 = $45,500
How Line 15000 Affects Your Benefits, Loans, and Taxes
This line may look small on the page, but it carries weight in many areas of life. It is not just for tax purposes. It helps decide your access to government help, financial products, and housing support.
Let’s say you apply for a student grant. The agency will ask for your or your parent’s income from Line 15000. That helps them know how much support you need. If you apply for subsidized housing or health programs, the same thing happens. The staff will ask for your full income. This line gives them the answer.
Banks also check Line 15000 when you apply for loans, credit cards, or a mortgage. They need to know your income before offering credit. A strong income can help you qualify for better rates. A lower one may require more paperwork or guarantees.

Even when you apply for provincial benefits, such as the Ontario Trillium Benefit or Alberta Child and Family Benefit, the government will review Line 15000. It tells them if your income falls within their limits.
Because of these reasons, it helps to know this number and keep it ready. It is more than just a tax number. It is a tool for life.
Where to Enter Line 15000 on Income Tax and Benefit Forms
Some forms from the government or banks will ask you to enter Line 15000 from a past tax return. This is common when you apply for programs like OSAP, CRA relief, or housing support.
To enter the number correctly, go to your T1 General tax return for that year. Look in the Total Income section. Line 15000 shows your full income before deductions. If you do not have a paper copy, you can log in to CRA My Account to view or download it.

Is Line 15000 the Same as Line 14 on T4?
No, these lines are not the same. Line 14 appears on a T4 slip and shows income from one job. It does not include any other income you earned during the year.
Line 15000 shows your total income from all sources. This includes all your T4s, plus income from self-employment, investments, pensions, and more.
If you earned income from several places, your Line 15000 will be higher than any single Line 14. That is why you should not use Line 14 as a full income figure when filling out forms.

How Line 15000 Affects Your Refund
Many people expect a refund at tax time. Others try to avoid owing extra. Line 15000 helps shape the outcome. A higher total income means you may owe more tax. A lower one could lead to more credits and a better refund.
Still, Line 15000 is just the beginning. Once you list your total income, your return shows the deductions you claim. These may include RRSP contributions, union dues, and support payments. The result becomes your net income. More deductions mean lower taxes, even if Line 15000 stays high.
Your refund depends on the mix between income, tax paid, and credits received. That is why it helps to track both your gross income and your deductions. Knowing your Line 15000 helps you plan ahead and estimate your refund before filing.
How to Correct Mistakes in Line 15000
Mistakes happen. If you enter the wrong income or forget to report something, you can fix it. The CRA lets you change a filed return using their “Change My Return” option online. You can also fill out a paper form and mail it in.
Always use the correct slips when adjusting your income. If you missed a T4 or T5, add it now. If your employer made a mistake on your slip, ask them for a new one. The CRA may ask for proof, so keep all documents ready.
Fixing your return early helps avoid bigger problems later. Wrong income could affect your benefits, your refund, or even your ability to apply for aid. It is always better to catch errors before the CRA does.
Does Line 15000 Work the Same in All Provinces?
Line 15000 follows the same rules in every province and territory. It is part of the federal tax return. The CRA uses one system across the entire country.
This means the number shows the same thing in Ontario, Alberta, Quebec, and all other regions. It always reflects your total income before deductions.
Some local forms may ask you to enter Line 15000. Even then, they still use your federal return as the source. You do not need to change anything based on where you live.
No matter your location, this line stays the same across Canada.
