According to the Internal Revenue Service, there are an estimated 1.3 million taxpayers who are owed a total of $1.3 billion in unclaimed refunds for tax year 2017. The IRS estimates that the refund amount of more than half of the unfiled returns is greater than $865. "The IRS always has a three-year window for filing a federal tax return and 2017's money is waiting to be claimed. To be clear: this $1.3 billion is just from unclaimed tax refunds for taxpayers who haven't filed yet, even though these taxpayers paid taxes throughout the year through withholdings," said Mark Steber, Chief Tax Information Officer at Jackson Hewitt. "Taxes are complicated enough and worrying about filing past tax returns only adds to the complexity. It's important to work with trusted Tax Pros to help navigate any complex tax issues that may arise for taxpayers."
