FYI, Credit Karma is providing free online tax filing regardless of your income.
In general, I think online tools become worth their cost when you are claiming mutliple deductions and have income from various sources across more than one state. Otherwise, the 1040EZ is where you should start.
just remember that credit karma makes all it's money from selling you credit cards... so by using them to fill out your taxes you give them all the info on your income info to further "personalize" these ads
After logging in to TurboTax (for the first time in a tax year) it asks you if it can share your data with its parent company (Intuit). Declining works and doesn't have any impact on TurboTax. However, based on how the UI for that looks like it might not be obvious for some people that data-sharing is optional.
