Here's who could get a bigger — or smaller — tax refund

Getting a tax refund is an eagerly anticipated event, with 3 of 4 taxpayers typically receiving a check from the IRS after they file their tax return. But this year, tax experts are warning that some people may receive a smaller check than normal. 

The biggest issue that could impact tax refunds is the enhanced Child Tax Credit, tax specialists note. 

People receive tax refunds if they've paid more to the IRS throughout the year than they owe, and the tax agency then cuts a check for the difference. Some taxpayers can also claim tax credits, which are a dollar-for-dollar reduction in the amount you'll owe to the IRS. These credits are typically aimed at specific groups of taxpayers, such as parents, students or low-income workers.
