The Earned Income credit is added to the refund meter as
you enter your income and personal information.
As
you lower your taxable income with deductions, you may lower the amount of your
Earned income Credit, thus lowering the dollar amount you see on the refund
meter.
The more information you
enter, the more accurate the refund meter will be, and will not be totally accurate (and thus truly
meaningful) until you have entered all of your information including
all income and expense/deductions.
