Property Taxes During Probate in Illinois: Who Pays and When

📘 Part of Inheriting a House in Illinois: The Complete Guide

Property taxes during probate in Illinois are the bill nobody warns you about. The mortgage servicer calls. The insurance company writes. The county treasurer does neither, because the county does not know your mother died. It just keeps sending a bill to the name on the deed, and that name is now the name of an estate.

Families find out about this in one of two ways. Either the executor opens the mail and sees it, or the bill goes unpaid long enough that the county starts the process it uses for every unpaid parcel in its jurisdiction, and a letter arrives that sounds far more alarming than the first one did. The first way is much easier.

This guide covers who is responsible for the tax bill while an Illinois estate is open, where the money comes from when the estate has no cash, what happens to the senior and homestead exemptions the house used to carry, and what to do in the first week.

The bill does not pause because someone died

There is no probate hold on a property tax bill. Illinois property taxes are charged to the parcel, not to the person, and the parcel does not care about the state of the estate. Opening an estate, closing one, waiting on a will contest, waiting on an out-of-state heir: none of it changes the billing cycle.

Two things follow from that, and they are worth saying plainly.

• An unpaid bill accrues consequences on the county's schedule, not on the family's. Those consequences are set by Illinois law and administered by the county collector, and they are the same for an estate as for anyone else.
• Somebody has to actually pay it. The estate is a legal entity that owns a house; it is not a person who notices mail.

The bill itself is usually the easiest part of an estate to keep clean, because the amount is knowable and the payment is public. In Cook County you can look up a parcel and see what is owed, what has been paid, and whether anything is outstanding, at the Cook County Treasurer. The collar counties all publish the same thing on their own treasurer sites.

Who actually pays it

In the ordinary case, the estate pays, and the payment is an expense of administration: money spent preserving estate property so it can be sold or distributed. The Illinois Probate Act of 1975 sets out the duties of a representative, including preserving what the estate owns, and the full text is available from the Illinois General Assembly.

In practice, one of four things is happening:

1. There is an escrow. If the house still has a mortgage and the servicer escrows taxes, the servicer pays the bill out of the escrow account and the family's job is to keep the mortgage current. The bill still arrives; it is a copy.
2. The estate has cash. The representative pays from the estate account. Keep the receipt with the estate records.
3. The estate has no cash but will. An heir or the representative advances the money personally and is reimbursed later out of the sale or out of estate funds. This is normal and legitimate, and the paper trail is the whole thing. Write down what was paid, when, from which account, and for which parcel.
4. Nobody is paying. This is the case that turns into a problem, and it almost always comes from a gap in assumption rather than a refusal. Everyone thought somebody else had it.

If several heirs will share the house, decide out loud, in writing, who is fronting the money and how they get it back. Our guide on multiple heirs and one house covers the wider version of that conversation.

What happens to the exemptions

This is the part that surprises people, and it is the reason a second bill can be larger than the first.

Illinois property tax exemptions attach to a person and their use of the home: a homeowner exemption for an owner who lives there, plus additional exemptions for a senior homeowner, for a senior with a qualifying income, for a veteran with a disability, and a few others. Every one of those is about the human being who lived in the house.

When that person dies, the basis for their exemptions ends. It usually does not end on the next bill, because Illinois bills a year behind: the bill you are holding is for a year the person was alive. It ends on a later bill, which means the number can rise after the family has already made a plan around the old one.

Two practical consequences:

• Do not budget a sale off last year's tax bill. If the house is going to be sold, and especially if an heir is deciding whether to keep it, ask what the bill looks like without the exemptions the person who died was claiming.
• Do not assume an exemption carries over to an heir. A surviving spouse who lives in the home is in a different position from a child who lives in another state. The Cook County Assessor's exemptions page explains which exemptions exist and who qualifies; the collar county assessors publish their own. If someone is going to live in the house, that person applies in their own name when they qualify, in the cycle the assessor runs.

There is also an appeal question. If the assessed value looks wrong, an estate can appeal the assessment the same way an owner can, in the window the assessor and the board of review publish. That window is a date on a calendar, not a rule of thumb, so get it from the assessor's office rather than from an article.

Cook County and the collar counties are not the same

The counties in the Chicago area run on their own cycles, publish their own installment schedules, and handle unpaid parcels through their own collectors. Cook County bills in two installments; the collar counties also bill in installments, on their own dates.

For an executor, what matters is less the mechanics and more this: look up the parcel in the county where the house actually sits, on that county's treasurer site, and read what it says. Do not carry a Cook County assumption into Will or Lake County. Our county guides for Cook, DuPage, Will, Lake and Kane cover how each court runs; the treasurer is separate from the court, and separate again from the assessor.

What to do in the first week

• Find the parcel number. It is on any old tax bill, on the deed, and on the county's property search.
• Look the parcel up on the county treasurer's site and write down what is paid and what is outstanding.
• Find out whether a mortgage servicer is escrowing the taxes. If it is, keep the mortgage current and the taxes take care of themselves.
• Put the next installment date on an actual calendar, with one named person responsible.
• Keep a single folder: bills, receipts, and a note of who paid what from where.
• If money is genuinely not available, say so early to the people who can help. A plan made in advance has options. A plan made after a notice arrives has fewer.

Frequently asked questions

Does the property tax bill stop while the estate is in probate?

No. Illinois property taxes are charged against the parcel and the billing cycle continues regardless of whether an estate is open, closed, or contested. Probate changes who signs the check, not whether one is owed.

Can the taxes be paid out of the sale instead of now?

Often yes, and it is common. At a closing, outstanding property taxes are typically settled out of the proceeds by the title company, which is why a house with unpaid taxes can still be sold. What you cannot do is let the county's own process run its course while waiting for a sale that has not been scheduled. If a sale is the plan, talk to a title company early so you know what will be paid at closing and what has to be handled first.

Who is responsible if the estate has no money at all?

Practically, whoever wants to keep the house from accumulating a problem. Legally, the expense belongs to the estate, and a person who advances estate expenses out of pocket is ordinarily entitled to be reimbursed from the estate. Document it. An undocumented advance between family members is how a straightforward reimbursement turns into an argument two years later.

Will the exemptions come off right away?

Not usually on the very next bill, because Illinois bills for a prior year. They come off later, which is exactly why families get caught: the plan was made around an old number. Ask the assessor's office what the bill looks like without the exemptions the person who died was claiming.

The house is empty. Does that change the tax bill?

Not in itself. Vacancy affects insurance far more than taxes, and that one is urgent in a different way. Our guides on vacant home insurance after a death and winterizing an empty inherited house cover it.
