I've run into an issue with how the tax planner handles SE Health Insurance premiums. I've tried entering them in 2 ways -
- in the planner Adjustments → Allowable S.E. Health Insurance Deduction field
- in the planner Business Income or Loss Schedule C → Unspecified Business Expense field
I believe doing so should be equivalent, but that's not what the planner summary reports shows.
In case 1, there is no change in the Business Income or Total Income values; i.e., the values reported are the same as if there were no SE Insurance premium payments. There is a decrease in the Taxable Income, but the Self Employment Tax is much larger so that the Tax Due is larger (apparently it caculates the tax based on the larger value for Business Income).
In case 2, the planner report the appropriate decrease in the Business Income and Total Income fields as well as a decrease in the Tax Due (in my case it turns into a refund).
Seems like a bug to me… or am I missing something?
