Why are refunds taking longer for the 2016 tax filing season?We are taking additional steps to protect Illinois taxpayers from identity theft and fraud. To ensure the security and confidentiality of taxpayer information, we have initiated a review process to combat against fraudulently filed returns. As a result of the new security measures, refunds may take longer to process this year than in previous years....Is the refund delay related to the budget situation in Illinois?No. Tax refunds are not subject to appropriation and, therefore, not being held up due to the absence of a state budget.
