The federal government has enacted legislation in past years to jumpstart the economy with an IRS stimulus plan. Using this, millions of dollars in tax money are refunded back to the American people in hopes that it will get pumped back into the economy through purchases and consumerism. The IRS offers an Economic Stimulus Payment Calculator so that taxpayers can estimate the amount that they will receive from the government. Those with lower incomes receive larger sums of money. It is important to understand, however, that only those individuals and families who complete their tax returns are eligible for the stimulus checks.
