This answer only applies to partners with linked returns.

When you first add credits and deductions from shared sections, Wealthsimple Tax will allocate them to the person who will benefit most from claiming them.

Once you and your partner have finished your returns, clicking Check & Optimize will run thousands of calculations to determine who should claim what credit, how you should split it, or whether you should carry it forward to a future year. Once the optimizer finishes, the Optimized Credits & Deductions table will appear and the optimized amounts will be applied.

Before you submit your return, you can review and change how we’ve allocated the amounts.

Here is the list of credits that get optimized.
