One thing is becoming clear...stay the hell out of Illinois. Those property taxes are brutal. Plus a 4.95% flat income tax and a sales tax. Ouch! Seems excessive, why does anyone stay and put up with this?
Let's just call it 5%. They aren't fooling me by making it 4.95% as if that's closer to 4 than 5% with little deductible. They didn't fool me when they raised it to 5% some years back under the premise of it being temporary, decreased it years later to 3.75% (which was still higher than it had been), but ~5% soon became permanent as I fully expected.
Illinois income tax is 65% higher than what it was most of my career, and there's very little I can deduct off my income. My property taxes have increased 56% since I bought my house while its value is about 20% higher . With local sales taxes added, I'm paying close to 10%. Illinois also charges a gasoline tax on top of the federal taxes. Is there any relief? Well, most grocery items are taxed at 1%, and IL doesn't tax SS and retirement income just yet, but some pro-tax folks can't stop talking about taxing retirement income so that we can keep paying those government pensions and healthcare. The move to a progressive tax structure has never caught any steam.
You're already paying more taxes due to increased home valuations and income increases over time, so percentage increases on top of that make you feel like you're getting hit twice as hard - increases on top of increases.
Why does someone stay? Different reasons. First, many are leaving. I have heard IL is among the top states for people leaving. 10 years ago, things didn't seem quite as bad. And, in my case, I'm living in a LCOLA as far as the cost of homes in good neighborhoods, which helps offset some of the high tax burden. But, my main reasons for staying are family/friends in the area and the fact that I have a senior IT job that I like (own office, no cubicle) that pays well that I will most likely FIRE from in 2019 or 2020. So that's right around the corner, and I have been investigating relocation options for the last 6 months. I want to do some traveling around to different areas before I make any final decisions.
