This has been live on the site for about a week and I totally forgot to mention it here. Thanks to a tax class I’m about to finish (tomorrow morning I’ll be trying to figure out how to do a corporation’s income tax provision for their financial statements…), I was able to glean quite a bit of knowledge about the US personal income tax. We were supposed to make a pretty simple spreadsheet to calculate some stuff.
I took it a step further so I could provide it to customers:

My personal favorite thing about this new bonus is the “?” feature. I did a bit of digging (okay, a lot of digging) and found tons of releveant IRS information on the various line items of the 1040. So when you click on the ? you should be brought to the IRS information on the web concerning that line-item. That should help you determine if your cousin’s wife’s mother’s sister’s father-in-law, who lived with you for 7 out of the last 12 months, and for whom you provide 69% support, is a dependent (and other fun things).
Yes, it’s called the Tax Forecaster – a momentary lapse of creative juices perhaps. Although Mortgage Analyzer, Retirement Planner, Debt Snowball, and Car Maintenance Schedule certainly aren’t much better.
I suppose it’s the functionality that really counts though – and they all have function.
