"Miscalculation" is very misleading and does not mean that the math is wrong - it means that the IRS changed something else on the tax return and now the EIC calculates differently. Usually the change they made changed the AGI due to unreported income, and that in turn changes the amount of EIC. The letter should tell you exactally what else they changed with it the actual reason.
