Error Code 95365
Error issue: There are entries for capital gains on T3 information slips and CRA has indicated that there may be a rounding issue.
Customer action: For all T3 slips in your return: - Remove the amount from Box 52, if applicable (leave it blank) - Enter the sum of Box 52 + Box 53 in Box 53 - Ensure Box 53 equals the amount in Box 21 If the error persists, try rounding the box amounts (21 and 53) to the nearest dollar and submit via NETFILE once more. Try filing after April 7, 2025.
Expected resolution date: Adjustments were made to the production system on April 7, 2025 to address erroneous instances of this error code due to rounding issues.
