The role of accountants is now to do tax planning for their clients. The best accountant is one that drags you into his or her office once a year to look at your finances and plan a strategy to limit what you will pay the IRS. This should occur at some point during the beginning of the tax year, not a week before your tax returns are due!
Unfortunately, a majority of accountants never took this step since they were to busy preparing the mountain of tax returns the federal and state governments now require. The evolving role of accountants, however, has let them return to the traditional position of coming up with proactive strategies to limit your tax bill. This is more interesting for them and obviously beneficial for you.
Many thought tax software would eliminate much of the need for accountants. Ironically, the changes in their duties has returned them to their traditional role of giving tax planning advice.
