If you are clueless about filing your income tax returns, you need the services of a tax preparer. And let's face it: most of us fall into this category. The U.S. tax code proves to be so confusing that over 80% of taxpayers give up on managing alone, including the head of the IRS.
As a tax preparer, you need to know your way around taxing legislation and regulations because if you do not, it will come back and bite you, you know where, fairly soon. This is not the kind of thing you would want to be bluffing with.
And even if your work is spotless, your client might still forget to sign the documents before submitting them, which is what happens to over a million taxpayers, nationwide, every year. So if you decide to be a tax preparer, rest assured, people who master this profession will never have to look hard for clients.
