OAS Tax Slips are generally available from February 1 each year via My Service Canada Account (MSCA). This gives the individuals who receive OAS an opportunity to check their T4A(OAS) details prior to preparing their income tax report.
T4A(OAS), the Statement of Old Age Security, is a form provided by the Service Canada to individuals who have received Old Age Security (OAS) during the previous calendar year. It provides details about taxable OAS income, eligible supplements, and any income tax deducted from payments.
What Are OAS Tax Slips?
OAS Tax Slips, officially known as T4A(OAS),, Statement of Old Age Security, are official documents issued by the Government to inform you about the Old Age Security benefits you have received in the current tax year. In most cases, people get their T4A(OAS) slip if they have received OAS benefits in the previous year.
You will need this form for reporting your income from OAS on your Canadian income tax form. Your OAS Tax Slip can have information such as:
- Old Age Security pension payments
- Guaranteed Income Supplement (GIS) amounts
- Income tax deducted from OAS payments
- Benefit adjustments or recovery amounts
When Are OAS Tax Slips Available in Canada?
The OAS Tax slips are generally available online via My Service Canada Account from February 1st onwards every year. In case of hard copies, the T4A(OAS) slip is typically sent by mail by the last day of February. The electronic copy of the slip is the quickest method for getting the tax details since you get the slip instantly without any delay through mail.

| OAS pension | Taxable Old Age Security income |
| Supplements | Eligible supplement payments |
| Tax deducted | Income tax withheld |
| Adjustments | benefits adjustments and recovery |
Checking your slip prior to the tax filing will ensure accuracy of the income you report to the government.
Can You Find Your OAS Tax Slip via CRA My Account?
T4A(OAS) can be accessed by you through CRA My Account when CRA gets the information regarding the slip from Service Canada. Nonetheless, My Service Canada Account is the main online source through which OAS Tax Slips can be accessed because Service Canada distributes the T4A(OAS) slip to the individuals. This implies that if your slip is not showing on CRA My Account, then probably the information has not been sent there yet.
What To Do If My OAS Tax Slip Is Missing
In case you have not yet received your OAS tax slip, try checking online before requesting an extra copy. You may:
- First check “My Service Canada Account.”
- Make sure that your mailing address is right.
- After processing, check “CRA My Account.”
- Contact Service Canada in case you can’t access your slip.
Getting the electronic copy will probably be faster than getting a new copy of the paper one.
Common Mistakes When Checking OAS Tax Slips
Choosing The Wrong Tax Year
The T4A(OAS) reflects income from the previous year. It is important to make sure that the tax year chosen is the right one before downloading the slip.
Using A Screenshot Rather Than An Official Slip
A screenshot taken from your account online cannot be used as a tax document. Use the PDF file available via My Service Canada Account.
Confusing OAS & CPP Tax Slips
OAS & CPP benefits are reported separately and use different tax documents.
| Benefit | Tax slip |
|---|---|
| Old Age Security | T4A(OAS) |
| Canada Pension Plan | T4A(P) |
If you are receiving both benefits, you might have to consider both tax slips for your tax return.
Why Keeping Your OAS Tax Slip Is Important
Your OAS Tax Slip will allow you to:
- Properly report your OAS income.
- Ensure your benefits for the year.
- Review your tax deductions.
- Keep accurate financial records.
It is always good practice to keep copies of government tax forms as this can be useful in the future while filing your taxes.
Prepare For Tax Season With Your OAS Tax Slips
By accessing your OAS Tax Slips earlier on, you will be able to go through the information and ensure that everything is accurate. You need to ensure that everything listed matches the Old Age Security benefits that you have received and save copies for your tax documentation purposes in the future.
In case there is any information that appears to be wrong or missing, you need to get in touch with Service Canada immediately to save yourself any trouble. Taking a few minutes to verify your tax documents can help make the filing process smoother and reduce the chance of errors when reporting your government benefit income.
