When you split your pension with your spouse, you will still see the full amount of the pension being split on that spouse's tax return.
The full amount of the pension being split is reported in the Total Income section of the tax return (Line 11500 - Pension Income).
Then the amount you are splitting with your spouse is deducted from your return in the next section to arrive at Net Income (Line 21000 - Deduction for Split Pension Amount).
The receiving spouse will only have one entry on Line 11500.
