Didnt maximize deductions and credits
Many readers saw returns where the client lost out on the full value of a deduction or credit, through either the carelessness or ignorance of the previous preparer.
Not checking eligibility for credits
With the IRS cracking down on various credits, good tax preparers find themselves explaining to clients that their previous preparer shouldnt have allowed them to take the EITC, the American Opportunity Tax Credit, or whatever the case may be, because theyre not actually eligible for it.
