Its been awhile since I've written. In the runs of my reports taxes are much higher than I actually pay. For NC state taxes, it probably has to do with the tax rate which has changed to a flat 5.75%. The state tax rate I'm calculating is over 6% in your program. For Federal Taxes my average tax rate from your report is around 25%, but the average tax rate I'm actually paying is <20%.
Have you thought of having the ability for users to input tax rates. For example I would put in 5.75 for NC. I would also put in the actual average tax rate I'm paying for Federal taxes.
What are your assumptions for deductions. Naturally state income and property taxes are quite important. So are charitable contributions, but I'm not sure how you take those into account.
Lastly, for Regular Asset Income how do you distinguish between realized and unrealized gains? Do you assume all dividends are qualified?
