The Illinois Department of Revenue (IDOR) is advising taxpayers to be vigilant when preparing tax returns in order to avoid several common errors which can lead to delays, rejections, or even penalties.
Common Filing Errors to Avoid
* Missing or Incorrect Bank Account Information - Taxpayers expecting refunds should choose direct deposit to their bank accounts to get refunds promptly. They should verify their account and routing numbers and ensure the correct information is entered on their returns.
* Failure to Report All Income - Taxpayers are required to report all sources of income including wages, dividends, freelance work, and investment earnings. Underreporting income can result in penalties and interest charges.
* Incorrect Filing Status - Wrong filing status can have significant consequences on tax liability and refunds.
* Mathematical Errors - Tax returns that include basic math errors, especially in calculations of credits, deductions, or taxable income, are flagged, resulting in delays.
* Missing Deductions or Credits - Taxpayers may be eligible for various tax deductions and credits. Failure to claim these credits or deductions can have taxpayers paying more tax than they really need to.
* Not Signing or Dating Returns - Unsigned or undated tax returns are considered incomplete.
* Filing Paper Returns Too Late - Paper returns take longer to complete and process, and delays can result in missing the filing deadline. IDOR recommends filing electronically for faster processing.
