Due to closures related to COVID-19, the Attorney General's Office will be operating with reduced staff. In recognition of this, Estates with returns and payments due between March 16, 2020 and April 15, 2020 will receive a 30 day extension for filing and payment. Please be aware that an extension of time to pay does not waive or abate statutory interest and that payments must be sent to the Illinois State Treasurer. A fillable form for making payment of the Illinois Estate Tax to the Illinois State Treasurer can be downloaded from the Illinois State Treasurer's website.
Please also be aware that there may not be staff available to receive returns in person at the Springfield office.
Those filing returns in Chicago may access the James R Thompson Center through the Lake Street entrance.
We *strongly* encourage estates to file returns and extension requests by mail. For Cook, DuPage, Lake, and McHenry counties, file with the Chicago office. For all other counties, file with the Springfield office.
