Looking at the 2026 Tax Planner, I am having a difficult time understanding how Quicken is calculating the over 65 tax exemption. It appears to add the $12K for married couples fine, if you do not exceed the $150K threshold. But, if you do go over that limit, the deduction does not appear to be calculated based on the IRS rule invoked. It is suppose to be decreasing the $12K by $.06/dollar over the limit. I have this calculation in an Excel s/s, and the two calculations do not match. Since Quicken does this calculation "behind the scenes", I cannot see how they are doing the actual calculation. Has anyone else experienced an issue with the deduction calculation?
