On the Foreign form there are lines for Pension income exempt under a tax treaty, Other pension income and Exempt portion. If the pension income isn’t entirely exempt from taxation, use the line Other pension income. Use the Exempt portion line if a pension entered on Other pension income is partially exempt.
Income reported on Pension income exempt under a tax treaty and Other pension income go to line 11500 of the T1 jacket. However, entries for Pension income exempt under a tax treaty and Exempt portion appear on line 25600 as deductions, thus offsetting their entries on 11500.
