Less stress at tax time: Having the confidence to do your own taxes will make filing less draining. Preparing your return will take less time, and you'll be less likely to procrastinate. Free tax preparation: Once you've learned how to complete your filing correctly, you won't need a tax preparer. Because your return affects your finances, you'll also have more of an incentive to get it right than a third party. Many people don't realize they're still liable for mistakes on their tax forms, even if they were prepared by someone else.
