How can I see why my tax refund was reduced by $3500 when I put my husbands T4 information into his return. I want to see exactly what changes and why.

The joint declaration is favorable when there is a significant disparity between the incomes of the two partners. It allows you to benefit from a family quotient, a mechanism that considers the composition of the household and could reduce the tax payable.

It's on a complete return you can compare.

Thank you for choosing TurboTax.
