Request to Reduce OAS Recovery Tax
The T1213OAS form, or Request to Reduce Old Age Security Recovery Tax at Source, is used in Canada for taxpayers who receive Old Age Security (OAS) benefits and wish to reduce the amount of recovery tax withheld at the source. Here’s why you might need to fill out this form:
- Income Estimates: If you anticipate that your annual income will be lower than the threshold for the OAS recovery tax (also known as the OAS clawback), you can submit the form to reduce the amount of tax deducted from your OAS payments during the year. This is useful for those whose income fluctuates year to year or who have one-time deductions that would lower their taxable income.
- Manage Cash Flow: By reducing the tax withheld, you can improve your monthly cash flow. This is particularly beneficial for seniors who rely on their OAS benefits as a significant part of their income and need more cash available throughout the year.
- Avoid Overpayment: Filling out the T1213OAS can help avoid significant overpayments of tax throughout the year, which would otherwise have to be claimed as a refund when filing an annual tax return.
The form requires you to provide details about your expected income and deductions so that the Canada Revenue Agency (CRA) can determine the appropriate amount of tax to withhold. It’s a good way to adjust withholdings to better match your actual tax liability, making financial planning easier.

Submitting the T1213OAS form
To submit the T1213OAS form, or the Request to Reduce Old Age Security Recovery Tax at Source, you will need to follow a few steps:
- Obtain the Form: First, you need to get a copy of the T1213OAS form. You can download it from the Canada Revenue Agency (CRA) website or order a paper copy directly from the CRA.
- Complete the Form: Fill out the form with accurate information regarding your expected income for the year. This includes reporting any deductions or credits you plan to claim that could affect your income level.
- Gather Supporting Documents: Along with the completed form, you’ll need to provide supporting documentation that justifies the reduction in your OAS recovery tax. This might include documents related to your income, deductions, or any changes in your financial situation.
- Submit the Form and Documents: You need to mail the completed form and any supporting documents to the CRA. The address to which you should send the form can be found on the form itself or on the CRA website. Make sure to send it to the specific address listed for handling T1213OAS forms to avoid delays in processing.
- Wait for Approval: After submitting the form, the CRA will review your application. If they approve your request, they will adjust the tax withheld from your OAS payments accordingly. If more information is needed, they may contact you.
It’s a good idea to submit the form well in advance of when you want the changes to take effect, as it can take some time for the CRA to process your request. Additionally, keep a copy of the form and your supporting documents for your records.
