Has anyone at Intuit noticed that their CPP Income Optimizer is seriously flawed. The formula for calculating monthly CPP benefits if you delay receiving payments until after age 65 produces an incorrect answer. It appears that they plugged in a formula some time ago, but haven't updated it. Just as an example, if you input a figure of $1,000 as the amount of monthly benefit that you would receive at age 65, the number that the TurboTax calculation provides for monthly benefits if you delay payments until age 70 is $1,300. The correct figure is $1,420. The calculation is actually quite simple and it is available on the Service Canada website (not CRA) and is also used correctly by various calculators and spreadsheets available on the internet. The problem, of course, is that since the monthly benefits calculation is incorrect, this feeds into the calculation of total lifetime benefits. Because of the error in the TurboTax formula, this can make a dramatic difference in the total benefits calculation which, in turn, means the result returned by the optimization function is not accurate.
