Pricing is constantly changing throughout the year as the tax filing season progresses. But I can tell you that if you buy basic, and then later upgrade it to Deluxe for exemple, then your total price paid (basic plus the upgrade cost) will be more than if you just purchased Deluxe from the get-go.
Use the website at https://turbotax.intuit.com/personal-taxes/cd-download/ and see if that helps you figure out the most cost effective option. Generally, if you have more than just W-2 income to report, the basic version just won't cut it in many cases.
Also on that website you can scroll all the way to the bottom and select "view forms" to see what tax filing forms are included with each version also.
Then if you want, post back here with the details of your income sources and we'll try to help you confirm your selection will meet your needs without having to learn "the hard way" you need to upgrade to the next higher version.
