Planning in Huntley
Local focus

Retirement planning for Huntley, including Sun City.

Huntley is home to Sun City, Del Webb’s 55-and-over community of nearly 5,500 homes. If you live there or are planning a move, the big questions tend to arrive in the same order: selling the old house, Medicare costs, and how to turn savings into income.

The move year. Selling your previous home is often the largest transaction in a decade. Most married couples can exclude up to $500,000 of gain on a home they have owned and lived in for two of the last five years ($250,000 if single). Gain above that is taxable, and it also counts as income for Medicare premiums.

Medicare looks back two years. Part B and Part D premiums are set by your income from two years earlier. A home sale, a large IRA withdrawal, or a Roth conversion this year can raise what you pay two years from now. We plan big income years with that lookback in view.

Turning savings into income. When to claim Social Security, which accounts to draw from first, and how to use the years before required distributions begin are tax decisions as much as investment decisions. Illinois doesn’t tax Social Security, IRA, 401(k), or pension income, so the planning centers on federal brackets and Medicare costs.

A hypothetical example: a couple moves to Sun City after selling a home with $600,000 of gain. $500,000 is excluded; the other $100,000 is taxable that year and can raise their Medicare premiums two years later. Knowing that before closing changes how much IRA money they take out that year.

We look at your tax return and your portfolio together, so choices like these are planned before they happen, not sorted out at tax time. See our retirement planning services.

If you want the plan without moving your accounts, start with the Retirement Tax & Income Review →, a one-time, flat-fee plan that answers whether you can retire and stay retired, and how to withdraw money from your accounts to lower your lifetime tax bill.

Common questions
FAQ

Huntley questions, answered.

Q.01

How far is your office from Huntley?

Our office is at 850 S McHenry Ave, Suite D, in Crystal Lake. From downtown Huntley it’s about 15 to 20 minutes: Algonquin Road east, then Randall Road north to McHenry Avenue. From Sun City, take Route 47 north to Algonquin Road; plan on about 25 minutes. Virtual meetings are available if you’d rather skip the drive.

Q.02

We’re moving to Sun City. Will we owe tax on selling our old house?

Often not, or less than you’d expect. Most married couples can exclude up to $500,000 of gain on a primary home they’ve owned and lived in for two of the last five years ($250,000 if single). Gain above that is taxed as a capital gain and counts toward Medicare premiums two years later, so it’s worth running the numbers before you close.

Q.03

Does Illinois tax my retirement income?

Illinois doesn’t tax Social Security or qualified retirement income such as IRA, 401(k), and pension distributions. Federal tax still applies, and Illinois still taxes interest, dividends, and capital gains. For most retirees, the planning that matters most is federal brackets and Medicare premiums.

Q.04

Why did my Medicare premium go up?

Part B and Part D premiums rise at certain income levels, based on your tax return from two years earlier. A one-time event, like a home sale or a large IRA withdrawal, can trigger a higher premium two years later. If your income dropped because you retired, you can ask Social Security to use a more recent year with Form SSA-44.

Q.05

Huntley is in two counties. Does that matter for my property taxes?

Yes. Huntley sits in both McHenry and Kane counties, and each county runs its own assessment and appeal calendar. Senior property tax exemptions are also applied for through your county, so check which county your home is in before assuming a neighbor’s deadline applies to you.
