Would you like to get some more insight into your financial history? Would you like advice on what to do in the future based on more data then what’s currently sitting in all of your accounts and portfolios?
If you’ve been working with the same accountant then maybe it’s fairly easy. Otherwise you’re trying to use tools like Mint.com to give insight based on what you have currently and/or for however long you’ve used the service.
How about a service or adding on the ability to an existing service that takes as many past tax forms as possible scanned in and generates analysis based on that historical information as well.
You already have major financial info. collected in your tax forms, how can we make those more useful?
