Doing Your 2015 Taxes on Windows: Turbo Tax

It’s no coincidence that you might recognize the names of the most popular online tax services. Each of them started their lives as traditional tax software that you installed on your Windows PC. TurboTax is the biggest of the three household names, and their traditional software is still available.

TubroTax hasn’t changed all that much. The TurboTax Deluxe features both state and federal programs, with access to Schedule A forms. If you have a regular job or receive 1099 forms for being a freelance or independent contractor, this is the version for you. Filing just your federal return with this version costs you $34.99. Adding in state costs another $36.99.

TurboTax Premiere grants users access to the forms and options they need for claiming their financial investments and properly filing any property rentals that they profit from.  Besides Schedule A, buyers get access to Schedule D financial instruments. These include ESPPs, socks and bonds. It’s Schedule E that includes “rental property income and tax deductions,” Intuit says. This version costs $54.99. Adding state to that is an additional $36.99, just like with the Standard Edition.

For everything in your life, there’s TurboTax Home & Business. Besides the other forms from cheaper versions, Schedule C items are included in this version, business tax deductions, self-employment and small business income being the big additions. This version costs $79.99, plus the $36.99 add-on for state.

What You Need to Know

Those are just the two biggest options to choose from. Some people have had a great experience with smaller outfits like TaxAct. If the service isn’t one of these three, you want to be sure that you read reviews before you input any of your personal information or provide a credit card. Look for comments on how easy the interface was to use. Keep a look out for anyone mention additional fees that weren’t made clear up front.

If you decide to go with a program that you install on your Windows machine, remember to save the files that the program leaves for you in a safe place besides your PC, like a flash drive. These files are helpful if anything happens to your PC and you need that information in the future.

Good luck with your 2015 taxes. Note that you don’t even need your computer in some cases. iPhone and Android apps allow you to do your taxes with your smartphone too. Gotta Be Mobile breaks down the apps you need for your taxes here.
