StudioTax also makes it easy to play around with different scenarios since it quickly recalculates the entire tax form when you change a value in any field. To take advantage of this, we played around our RRSP contributions (we each had room for one final contribution from our 2012 income) and donations to see if we needed to claim the entire values to minimize our tax, or if we could carry any of it over to the following year(s). In my case, I needed all of my RRSP contribution plus all of the donations that we each made in order to reduce my taxable income. But we were able to carry forward some of Rich's RRSP deduction to next year since applying all of it did not further reduce his tax burden. It was a matter of repeatedly running the "Wizard" option, fiddling with the RRSP deduction number and then checking the recalculated tax owed until we could not bring down the tax owed any further.
donation here in order to help fund future versions of the program. They accept credit cards, pay pal or cheque. We will definitely make a contribution to thank them for making our lives so much easier.
