High income amounts
We have observed numerous situations in which Efilers have inadvertently entered extremely high income amounts in fields on the returns and transmitted these amounts.
We are encouraging Efilers to review and verify the entries before transmitting their returns. High amounts in certain fields may be valid in some situations but in some cases, there appears to be confusion with placement of the decimal point (eg., an intended amount of $1234.56 is transmitted as $123456.00)
