Illinois HOA board only gives details of budget after it's been voted on

Does a HOA have an obligation to provide a copy of the budget to homeowners prior to the board voting for approval?

How many days prior does the HOA have to provide the copy of the budget before the next homeowners meeting, in which the board will vote for approval?

I don't think our HOA board is doing this. They only talk about the budget and its details at the meeting.
