The Internal Revenue Service says an estimated 26,300 taxpayers in Virginia could be owed federal tax refunds for 2010.
    
The IRS says in a news release that it's holding more than $22 million in unclaimed refunds for Virginians who didn't file a federal tax return in 2010.
    
Half of the potential refunds are estimated at $568.
    
The IRS says some people might not have been required to file tax returns because they didn't earn enough income. Taxes were still withheld from their wages, or quarterly estimated payments were made.
    
Taxpayers must file a return for 2010 no later than April 15 in order to collect the refunds.
    
The IRS says refunds might be held if these taxpayers also haven't filed returns for 2011 and 2012.
