IL HB3480

Restricts grounds for declaring a tax sale in error by requiring errors made by assessors or county officials to be "material to the tax sale" and excluding errors in property description, physical characteristics, location, or pictures.

Removes provision allowing a sale in error when a bankruptcy petition is filed after the tax sale; instead permits a sale in error only if a bankruptcy petition was filed prior to the tax sale and an automatic stay is active on the sale date.

Makes the $100 fee paid by tax purchasers in counties with 3,000,000+ inhabitants nonrefundable.

Requires notice of expiration of the redemption period to be delivered to the sheriff (or coroner/private detective in certain circumstances) at least 5 months prior to redemption expiration, rather than 3-6 months.

Clarifies that when a sale in error is declared under Section 22-35, the tax purchaser may retain a lien on the property until paid with 5% annual interest, rather than having the entire sale set aside.
