Filling out the Illinois Tax form can be straightforward, but many people make common mistakes that can delay their refunds or lead to penalties. One major error is failing to provide complete personal information. It’s essential to include your full name, Social Security number, and the same for your spouse if filing jointly. Leaving out even one digit of the Social Security number can cause issues.
Another frequent mistake is not checking the correct filing status. Whether you are single, married filing jointly, or head of household, it’s crucial to select the right option. Choosing the wrong status can affect your tax rate and the deductions you qualify for.
Many taxpayers also overlook the income section. Ensure you report your federal adjusted gross income accurately. Mistakes in this area can lead to discrepancies that might trigger an audit. Remember, only whole dollars should be entered. Rounding can lead to errors.
Additionally, some individuals forget to include all necessary attachments. For example, if you have income from a W-2 or 1099, these forms must be stapled to your tax return. Not including them can delay processing and refunds.
Claiming exemptions incorrectly is another common pitfall. Make sure to check all applicable boxes and calculate the exemption amounts accurately. If you are 65 or older or legally blind, don’t forget to include these exemptions, as they can significantly reduce your taxable income.
People often miscalculate their total tax due. When adding lines for your tax liability, double-check your math. Errors here can lead to either underpayment penalties or overpayment, which means waiting longer for your refund.
Another mistake involves the payment section. Be sure to include all applicable payments and credits. This includes Illinois income tax withheld and any estimated payments. Missing these can result in an incorrect balance due.
Finally, many filers forget to sign and date their return. Both you and your spouse must sign if filing jointly. A missing signature can delay the processing of your return. Always review the entire form before submission to catch any overlooked details.
