Before you start filling out your tax forms, you can get a rough estimate of your taxes with the TaxCaster app from TurboTax. Perhaps you want to ease your mind before you get started. Or you need to decide to file for an extension or to run out and put some money in an IRA. Maybe you want to plan for a big splurge when you get your refund. Answer a few questions, enter your yearly income and find out how much money you owe in minutes.
This app is not for people who run their own business, freelancers or consultants who file taxes using a Schedule C, or other special circumstances. Still, you can play around with income amounts to see your tax obligation at different income levels. H&R Block Mobile also has a tax estimator.
