How to fill out Illinois ST-1 Form (Quarterly/ Monthly Tax)
1st Quarter filing due April 20th!

I made this video primarily for my own memory but thought it might be helpful for others.
*Includes how to calculate how much taxes you owe to the state.
Please note: I'm not an accountant, tax preparer or a state employee, just a small business owner that needs to file taxes!
