Many people use TurboTax or H&R Block to file their taxes online. It’s usually quick and easy, and, for some filers with very simple tax situations, it may work. But online software can only use the numbers it’s given. It isn’t able to talk to you about your financial or employment situation, possible deductions you may not know about, or your future goals.
National chain services like H&R Block and Liberty Tax do provide a certain level of human interaction. But their tax preparers have minimal training and are basically walking you through software similar to TurboTax. Your finances are too important to leave to a machine.
