The Louisiana Department of Revenue says more than $17.5 million in unclaimed state tax refunds is waiting for nearly 23,000 individual and business taxpayers. How Louisiana Taxpayers Can Claim Their RefundTaxpayers who received the letter have two options. They can visit the Louisiana Department of Revenue’s Unclaimed Refund webpage and provide the requested information through the secure Louisiana Taxpayer Access Point portal. Refunds that remain unclaimed will be transferred to the Unclaimed Property Division of the Louisiana State Treasurer’s Office, as required by state law. A few minutes of attention could reunite thousands of Louisiana taxpayers with money that already belongs to them.
