Tax-Aware Retirement Planning, Chicago

What Illinois actually exempts

Illinois allows you to subtract the federally taxed portion of qualified retirement income when calculating state tax. In practice that covers Social Security, pension income, distributions from 401(k) plans and IRAs, and government plan income, including amounts converted from a traditional IRA to a Roth.

For a retired household this is a genuine structural advantage, and it is worth understanding precisely rather than loosely. It does not mean retirement is untaxed. Federal tax applies to all of the same income. What the subtraction removes is the second layer, and with it the state-level cost of any decision that increases income in a given year.

The consequence is narrower than people assume and more useful. There is no state bracket to manage alongside the federal one, which means every timing decision, every withdrawal and every conversion gets evaluated against a single set of federal consequences. That simplifies the modeling considerably and it concentrates the stakes.

The three things it does not reach

The subtraction is generous but specific, and three common items sit outside it.

• Capital gains in a taxable brokerage account. These are not retirement income and are subject to the state's flat rate, alongside the federal treatment. That makes the taxable account the one place where an Illinois retiree still has a state-level decision to make, covered in capital gains in retirement.
• Earned income. Part-time or consulting work after retirement is wages, taxed normally at the state level, and it can also affect other calculations if you have not yet reached full retirement age.
• Property tax. Untouched by any of it, and for a long-tenured suburban homeowner frequently the largest fixed cost in the plan. It belongs in the spending projection as its own line, with an assumption about growth.

Illinois also levies its own estate tax at a threshold well below the federal one, which a surviving spouse cannot inherit the unused portion of. That is covered in the Illinois estate tax.

Why withdrawal order matters

Three account types, three tax treatments. Taxable accounts are taxed on the gain, on their own schedule. Tax-deferred accounts produce ordinary income on every dollar withdrawn. Roth and HSA withdrawals, when qualified, do not raise your income at all.

That last property is the one most households underuse. Raising income has knock-on effects beyond the bracket itself, so an account that funds spending without raising income is valuable precisely in the years when something is being measured against your income.

General illustration. Qualification rules apply to Roth and HSA withdrawals, and this is not tax advice. See using a health savings account in retirement.

There is no universally correct order. Drawing taxable first preserves deferral but can leave low brackets unused in the very years they are widest. Drawing tax-deferred first uses those brackets but accelerates income. The right sequence is the one modeled against your own numbers and revisited annually, which is what tax-aware retirement planning covers as a service.

The conversion window

For most households there is a stretch between the last paycheck and the start of Social Security and required distributions when income is the lowest it has been in decades, and the lowest it will be again. That window is finite, it closes on a known date, and it is the main reason conversions get modeled at all.

Converting during it means paying tax now, at a rate you can see, to remove future ordinary income and shrink the balance that required distributions will eventually be calculated from. Whether that trade is worth making depends on your current rate against your expected future rate, on how the tax is paid, and on what else the added income touches in the same year.

Two cautions. Converting is a taxable event, and paying the tax from the converted amount itself substantially weakens the case for doing it. And a steady pension narrows the window considerably, because income you cannot switch off is already occupying the bracket room a conversion would have used. The mechanics of what forces the issue later are in required minimum distributions.

The two-year delay nobody plans for

Medicare premiums are tiered by income, and the income used is from a return filed two years earlier. A conversion or a large withdrawal therefore carries a second cost that arrives long after the decision looks finished, and it surprises people every year.

The tiers are cliffs rather than slopes: crossing one by a small amount moves the whole premium to the higher tier. That makes the final increment of income in a year worth watching closely, and it is the single strongest argument for modeling a conversion before executing it rather than after. There is also a form for appealing a surcharge triggered by a one-off event such as retiring, covered in Medicare late enrollment penalties and IRMAA appeals.

Added income can also pull more of your Social Security benefit into taxation at the same time, which is a separate effect running in parallel. The Social Security tax torpedo covers that interaction.

What a planning year looks like

Tax-aware planning is a yearly rhythm rather than a one-time exercise.

1. Early in the year. Project the year's income from the plan: what is already fixed, what is discretionary, and roughly where that lands.
2. Through the year. Fund spending from the account the sequence calls for, and note anything unusual, such as a property sale or a one-off expense.
3. Autumn. The decision point. With most of the year's income known, size any conversion, any harvesting, and any charitable giving against the room actually left.
4. At filing. Compare what happened against what was projected, with your CPA, and carry the difference into next year's assumption.

The autumn step is the one that gets skipped, and it is where most of the value sits. Decisions made in December with the year's income largely known are better decisions than the same ones made in January on an estimate.

Where the CPA line sits

This practice does not prepare tax returns and does not give tax advice. The division is clean: your CPA files the return and advises on tax; the planning work supplies the projection, the sequencing and the modeling of what a given decision would do before it is made.

That division only works if the two sides talk. A conversion sized without the preparer's input is a guess, and a return filed without knowing what the plan intended for next year loses information. Where there is no CPA, the planning still happens, and we are glad to work alongside one you choose. New federal deductions for retirees covers two provisions worth raising with yours.

Serving Worth

Worth sits on the Cal-Sag Channel just north of the Palos Heights office, a compact village of long-tenured households. The work here often starts before any tax question does: consolidating accounts scattered across a long career, so that there is a single picture to sequence withdrawals from in the first place.

For Worth households that means tax-aware withdrawal sequencing coordinated with your CPA, retirement income planning that states which account funds which year, investment management built for the distribution phase, and Medicare enrollment timing mapped against the retirement date. The office is minutes away, so reviews happen in person.
