FAQ — TAX PREPARATION IN ILLINOIS
Does Illinois have a state income tax?

Chicago has specific compliance rules for businesses but no separate city income tax.
Do remote workers need multi-state filings?
Often yes, especially those with CA/NY/TX employers.
Do Illinois landlords need depreciation support?

As a small business owner in Illinois, how do the 2026 state income tax rates for corporations and individuals affect my pass-through entity's tax obligations?
For 2026, Illinois maintains a flat individual income tax rate of 4.95% and a corporate income tax rate of 7.00%. If your small business is structured as a pass-through entity (like an S-Corp or LLC), your business income will be taxed at the individual rate on your personal return, plus the 1.5% Personal Property Replacement Tax (PPRT) that applies to all businesses in Illinois. Understanding this distinction is crucial for accurate tax planning and estimated payments.
When are the estimated tax payment deadlines for self-employed individuals in Illinois for the 2026 tax year, and are there any specific state penalties for underpayment?
For the 2026 tax year, estimated tax payment deadlines for self-employed individuals in Illinois generally align with the federal schedule: April 15, June 15, September 15, and January 15 of the following year. Illinois does impose penalties for underpayment of estimated tax if you don’t pay at least 90% of your current year’s tax liability or 100% of your prior year’s tax liability through withholding or estimated payments. Our service can help calculate these to avoid penalties.
Can I deduct my property taxes paid to my local Illinois municipality (e.g., Cook County) on my 2026 state income tax return, or is this only a federal deduction?
While property taxes paid to your local Illinois municipality are generally deductible on your federal income tax return, subject to the SALT cap, they are not directly deductible on your Illinois state income tax return. Illinois does not have a provision for deducting local property taxes when calculating your state taxable income. However, there are potential property tax credits available for certain homeowners, which we can help you explore.
