Your rights under 765 ILCS 710/1

Under 765 ILCS 710/1, landlords in Illinois must return a tenant's security deposit — or the balance after lawful deductions — within 45 days after the tenancy ends and the tenant vacates the unit. Along with the return, the landlord must provide a written, itemized statement of any deductions within 30 days. Failure to provide this statement is independently actionable.

If a landlord fails to return the deposit within 45 days, Illinois law provides for 2x the wrongfully withheld amount as damages.

Illinois requires landlords to pay interest on security deposits held for longer tenancies. The current rate is approximately 5.01% per year. Interest must be paid when the deposit is returned.
