Are Tenants Entitled to Interest on Their Security Deposit in Illinois?
Illinois law does require landlords to provide interest on held security deposits, but only in some situations, and some cities, like Chicago, have different rules regarding interest on security deposits. The current interest rate in both Illinois and Chicago is 0.01%.
By Illinois state law, landlords must pay interest on security deposits if they own 25 or more units (either in one building or in a complex of buildings) and the security deposit is held for six months or more.
In Chicago, tenants are entitled to interest if their security deposit is held for longer than six months. In this case, the landlord owes interest from the first day of the lease term. Dwelling units in owner-occupied premises containing six or fewer units are exempt from this rule.
When a tenant is entitled to interest on their security deposit, it must be either credited towards rent or paid to the tenant directly within 30 days after the end of each 12-month rental period if the accrued interest is $5 or more. However, the $5 limit does not apply in Chicago, so interest must always be paid to eligible tenants on an annual basis.
