You can but you have to apply now for gun season. For bow you can buy tags over the counter later on.

For gun seasons, go the the Illinois DNR website. You have to apply for a specific county, or hunting area. Then wait. If you draw a tag theywill mail it to you.

Good luck. This is the worst state when it comes to gun hunting for deer. Bowhunting, thats another story, buy all the tags you want and take all the does you want.

Good Hunting,
