Hi, I am a Illinois resident and currently doing an internship in Florida. I will be here only for 13 weeks and my expected income from this internship is $9880. I also have other sources of income from Illinois, so my expected total income for this year will be around 45~50K. I heard that when I file an income tax report in Illinois, I will have to pay state income tax to Illinois for the Florida income portion, since Florida does not collect income tax. Out of the income of $9880, how much should I put aside? Thank you in advance for your answers.
