Claim the disability tax credit

This option will be available to you if you have applied and been approved to claim the disability tax credit (DTC) for:

• Yourself
• Your dependant(s)
• Your spouse or common-law partner

If not, it will not be shown.

For more information on who is eligible for this credit and how to apply, refer to What is the DTC.

If do not want to claim the DTC, select Next to bypass this credit and continue to "Change my return".

You can claim the DTC on one or more of your returns by using this option. It will apply both the federal and provincial or territorial credits to their maximum amounts, if available, for each year:

• Disability amount for self
  • Select each year you want to claim the DTC for. Do not select years for returns you have already claimed it on.
• Disability amount transferred from a dependant
  • If you have one eligible dependant, select each year you want to claim the DTC for. Do not select years for returns you have already claimed it on.
  • If you have multiple dependants you are eligible to claim the credit for in the same tax year(s), select all the dependants and tax year(s) you want to claim, including any dependant(s) already claimed on your return(s).
• Disability amount transferred from your spouse:
  • Select each year you want to claim the DTC for. Do not select years for returns you have already claimed it on.
  • If needed, you can update your spouse’s or common-law partner’s adjusted taxable income on lines 351/36100 and 5912/59120. For more information, refer to Schedule 2.
• For all types of claims:
  • If you or the person you are claiming the credit for are under 18 years of age at the end of the year, enter any related child care expenses or attendant care expenses that you or another individual claimed in the year. For more information, refer to Attendant care and care in a facility and the federal, provincial, or territorial worksheets.

After you make your selections and update the required fields, select Next. We will ask if you want to make any further adjustments to your return(s).

• Select Yes if you would like to make more changes. This will take you to the Select the year screen where you can choose which year you want to make changes to.
• Select No if you do not have any more changes to make. This will take you to the Provide additional information screen, followed by the Review and submit screen that will show you a summary of your changes.

Select the year

Select the year you want to change from the list of available years in the drop-down menu. Then select Next.

Generally, you can request a change only to a tax return for any of the 10 previous calendar years. For example, if you make a request in 2024, changes must relate to the 2014 or later tax returns.

If you want to change a return for a year that does not appear in the list in the drop-down menu, send the request to your tax centre in writing.

If you select a year you have already completed, the entries you made in the Provide Additional Information step for that year will not be saved. You will have to redo the step.

Additional options in "Change my return"

You can make online requests to apply these losses:

• Carry-back amounts, such as:
  • Capital losses
  • Non-capital losses
• Carry-forward amounts, such as:
  • Farming losses
  • Fishing losses
  • Restricted farm losses

You can make an online election to split pension income.

Search for tax line feature

Enter either:

• A line number from the income tax and benefit return, such as "12600"
• Text to describe the line you want to find, such as "rental income"

From the search results list, find the line you want to change and click on it. For example, click on line 12600 to change rental income.

If you want to go to a specific section of the return, select that section from the drop-down menu below the Search box. For example, you can find line 12600 by selecting Total Income in the drop-down menu.

Change a line

If you use the Search feature, the cursor will appear in the New Amount box of the line you want to change. Enter the dollar amount you want to show on your return after the change is complete.

If you select the section of the return from the drop-down menu, enter the new amount in the box beside the line you want to change. If the line does not appear, use the Search feature to enter the line and select it to add it to the related section below. Enter the dollar amount of the change you want to make in the New Amount box.

Add amounts from tax information slips

Use this option to add amounts from the tax information slips that are on file with the Canada Revenue Agency (CRA).

The slips are grouped together based on their type and labeled with their last "Date modified." If the date is bolded, it means we changed the slip after the most recent (re)assessment.

Some slips have additional fields you can change as needed. If this applies, update these fields before adding your slips:

• Exchange rate
  • If a slip is not reported in Canadian dollars, enter the rate used to convert this to $CAN. You can find these rates on the Bank of Canada website. The default rate is 1.00.
• Percentage of slip claimed
  • If a slip has income from a joint account, enter the percentage of the slip you are claiming on your return. The default amount is 100%.

You have 2 options:

• Add selected slips to my return
  • Select each slip you want to add to your return from the list and select this option to have them added to the Old Amount reported on your return.
  • Add only the slips you have not previously reported on your return to avoid duplicating the amounts.
• Match all slips to my return:
  • Select this option to total all of the information slips shown in the list and change the New amount reported on your return to equal the sum of their values.

After selecting one of the options, you may be asked to determine the line for the amounts to be reported on.

Then you will get a summary of the changes you are requesting. You will be able to remove a change from the list or modify any of the values listed to match any additional information you have.

If you agree with what is shown on the summary, select Add changes to include these amounts to your existing request. 

You can add any additional changes or review your request before submitting the changes.

Provide additional information

After making changes, you may need to provide more information:

• A mandatory correction – Provide the identified information before you can submit your change.
• A mandatory question – Respond yes or no and select Continue.
• An optional correction – You may want to provide more information if the warning applies to your tax situation.

After each stage, select Confirm my answers to continue with your request.

If you select Back to return to the Change my return main page, the entries you made during this step will not be saved and you will have to make corrections or answer questions again.

If no additional information is needed, and all responses have been provided, select Next to get to the Review and submit page.

Review and submit your changes

The Review and submit page summarizes the changes you made.

• Old Amount is the dollar amount currently showing on your return
• Change Amount is the dollar amount of the increase or decrease you are requesting
• New Amount is the dollar amount you want to show on your return after the change is completed

You may get a message stating that certain amounts were changed automatically. You can see the results of these changes in the summary for each year.

If you want to make other changes, select Edit. This will take you to the Provide Additional Information step for this year and you will have to redo the step.

If you want to make changes to another year, select Add another tax year (when available).

If you do not need to make further changes, read the certification statement, tick the box to agree, and select on Submit changes.
