The Illinois Department of Revenue (IDOR) has issued a reminder to taxpayers regarding the process for correcting errors on previously filed state income tax returns. If taxpayers identify mistakes such as miscalculations, missed deductions, or unreported income, they are required to file an amended return.
"Taxpayers who discover an error on a previously filed state income tax return—such as a miscalculation, a missed deduction, or unreported income—they are required to file an amended return to correct the mistake," states the IDOR.
This guidance aims to ensure that all tax filings are accurate and up-to-date. Taxpayers should review their past submissions and take appropriate action if discrepancies are found.
