Thinking about leaving Illinois for Boca Raton? Here is how the tax picture changes, how to establish Florida residency properly, which communities fit North Shore and western-suburb buyers, and how to time your purchase.
Every fall I take a handful of calls that start the same way: "We've spent our last winter in Chicago." Some of these families have wintered in Palm Beach County for years. Others have never spent more than a long weekend here. Either way, the move from Chicago to Boca Raton is one of the most common relocations I help with, and it rewards planning more than almost any other.
This guide covers what I walk Chicago-area buyers through before they ever tour a home: the tax picture, how to establish Florida residency properly, which communities tend to fit people coming from the North Shore or the western suburbs, and how to time the purchase.
The Tax Picture: Why the Math Changes So Much
For most of my Illinois clients, taxes are the conversation that starts the move. The differences are structural, not marginal.
- State income tax. Illinois levies a flat personal income tax of 4.95%. Florida has no state personal income tax. For a household with significant wage, business, or investment income, that difference alone can be meaningful every single year.
- Estate tax. Illinois has its own estate tax, with an exemption of $4 million — far below the federal threshold. Florida has no state estate or inheritance tax. For families with substantial estates, this is often as important as the income tax savings, and it is worth a conversation with your estate attorney early.
- Property tax. Illinois property taxes are among the highest in the country, and Cook, Lake, and DuPage County owners feel it. Florida property taxes are not trivial on a luxury home — millage in Boca Raton is real money — but the homestead protections below change how that bill behaves over time.
The income tax savings get people to call. The estate tax and the homestead cap are usually what make the decision permanent.
Florida Homestead: The Part Most Relocating Buyers Underestimate
Once Florida is your permanent residence and you own your home as of January 1, you can apply for the homestead exemption with the Palm Beach County Property Appraiser. The application deadline is March 1. Homestead gives you two things:
- An exemption of up to $50,000 off the assessed value.
- The Save Our Homes cap, which limits annual increases in your assessed value to 3% or the change in CPI, whichever is lower — no matter how fast the market moves.
That cap is the quiet engine. In a rising market, the gap between market value and assessed value can widen year after year. One caution: when a home sells, its assessment resets for the new owner. The taxes the seller pays are not the taxes you will pay, and I always have my buyers estimate the post-purchase bill before they write an offer.
Establishing Residency the Right Way
Buying a house in Boca Raton does not, by itself, make you a Florida resident. States with income taxes — Illinois included — can and do look closely at whether a move is genuine. The families who handle this cleanly tend to do the following:
- File a Declaration of Domicile with the Palm Beach County Clerk.
- Get a Florida driver's license (new residents are expected to do so within 30 days), register vehicles here, and register to vote in Palm Beach County.
- Apply for homestead on the Florida home.
- Move the things that signal where you actually live: primary physicians, the bank relationship, club memberships, safe deposit box, the family photos and heirlooms.
- Keep an honest record of days spent in each state.
If you are keeping a home in Winnetka, Hinsdale, or the Gold Coast, the documentation matters even more. I am not a tax advisor, and residency rules have nuances I will always send you to a CPA or tax attorney for. My job is making sure the real estate side — closing timing, the January 1 ownership date, the homestead filing — lines up with the plan your advisors build.
Where Chicago Buyers Tend to Land
There is no single "Chicago neighborhood" in Boca Raton, but I do see patterns in what people are looking for.
If You're Coming From the North Shore
Buyers from Lake Forest, Winnetka, and Glencoe often want lake-life equivalents: water, established trees, and a sense of permanence. Royal Palm Yacht & Country Club is the natural first look — deepwater canals, fast Intracoastal access, and an exclusive golf and yacht club. Homes there span from renovated classics to new estates well into eight figures. Highland Beach, the quiet barrier-island town just north of Boca, appeals to those who want to wake up on the ocean without a downtown around them.
If You're Coming From the Western Suburbs
Families from Naperville, Hinsdale, or Oak Brook often prioritize space, schools, and a gated, amenity-rich community. West Boca's private clubs fit that profile well. The Oaks, Boca Falls, and St. Andrews Country Club each offer security, larger lots, and club life — but they live very differently, from membership structure to the age of the housing stock. Newer construction such as Boca Bridges draws buyers who want a turnkey home without renovation risk.
If You're Coming From the City
Gold Coast and Lincoln Park buyers sometimes miss walkability more than they expect. East Boca near Mizner Park, and downtown Delray Beach along Atlantic Avenue, give you restaurants and an evening scene within a short walk or drive — with the beach at the end of the street instead of the lakefront path.
What Surprises Chicago Buyers Once They're Here
- Insurance is a line item you underwrite before you buy. Windstorm coverage, roof age, impact glass, and flood zone all affect what a home costs to own. I get quotes started during the inspection period, not after.
- Club membership is its own decision. In many Boca communities, equity or mandatory memberships carry initiation fees and annual dues that should be part of the budget from day one.
- Construction standards are different. Florida's building code has been strengthened repeatedly for wind. The year a home was built, or when it was substantially updated, matters more here than it does in Illinois.
- Getting back is easy. Palm Beach International and Fort Lauderdale-Hollywood both run nonstop service to O'Hare, and Boca Raton's own airport handles private aviation. Most of my Chicago clients keep business and family ties without much friction.
Timing the Move
Chicago buyers often plan around the school year and the first freeze. From a real estate standpoint, a few dates matter more:
- January 1. Owning the home as your permanent residence on January 1 is what qualifies you for homestead that tax year. A December closing can be worth a full year of the exemption and the start of your Save Our Homes cap.
- Season. Inventory and competition in Boca's luxury market typically build from late fall into spring as seasonal buyers return. Shopping in the fall often means more room to negotiate and more attention from sellers who want to close before the new year.
- Your Illinois sale. If you are selling in Chicagoland, spring is usually that market's strongest window. Many clients buy here first, establish residency, and list their Illinois home in the spring. We plan financing and bridge options around that sequence.
How I Work With Relocating Buyers
Buying from more than a thousand miles away requires a broker who does more than send listings. Before you fly down, I build a short list around how you actually live, preview homes in person, and send honest video walkthroughs — including what a listing's photos leave out. When you arrive, we see only the homes worth your time. Through contract, inspection, insurance, and closing, you deal with me — not an assistant, not a showing coordinator.
If you are weighing a move from Chicago to Boca Raton, I'm happy to walk through the timing, the communities, and the numbers with you — no pressure, just a clear picture. Reach out to Julian Rizzuto Flancbaum at LPR Properties, and let's talk about what the next chapter looks like.
