Chicago-Area Sales Taxes Changed Again in 2026: Here’s What Small Businesses Need to Know

If you own a retail, restaurant, grocery, or liquor business in Chicago, 2026 has brought a surprising number of changes to the taxes you’re responsible for collecting.

And because apparently sales tax in Illinois was not already complicated enough, these changes took effect on three different dates, involve multiple taxing authorities, and in one particularly frustrating case may require businesses to distinguish between alcohol their customers intend to drink on-site and alcohol they’re taking with them.

So you might want to grab a drink of your own as we break down what changed, when it changed, and most importantly, what small business owners need to do about it.

January 1: Illinois Eliminated the State Grocery Tax — But Not Really

Effective January 1, 2026, Illinois eliminated its statewide 1% sales tax on qualifying groceries.

Which sounds totally straightforward until you learn that the same legislation allowed municipalities and counties to enact their own 1% grocery tax to replace it. And, of course, many did. (Wouldn’t you, if you were in an area that just got its state budget cut?)

So, in municipalities like Chicago that adopted the replacement tax effective January 1, the amount customers paid on groceries didn’t change — just where that 1% was going and how retailers report it.

The Illinois Department of Revenue specifically warned retailers that they are responsible for determining whether the municipality where they make sales (or the county, for sales in unincorporated areas) has enacted the local grocery tax or not. IDOR subsequently issued a compliance alert after discovering that some retailers had stopped collecting the tax when they shouldn’t have.

(Big freaking surprise: you tell small business owners that on top of the long list of other things they have to navigate, now they also have to figure out whether their municipality enacted a tax that they’ve just been told was repealed… and you say there was confusion? Sigh.)

And if you’re in the Chicago area, there’s another layer: because the regional transit tax on qualifying groceries never went away; the part that was repealed didn’t include this portion. In fact, this part was recently increased by another quarter-point (more on that later).

What businesses should do: If you sell groceries, verify the current rate for every location where you make sales using the Illinois Department of Revenue Tax Rate Finder. Don’t assume that “Illinois eliminated the grocery tax” means your POS should be programmed to stop charging 1%. (Qualifying “groceries” generally means food for human consumption off-premises. Alcohol, soft drinks, candy, cannabis-infused foods, and food prepared for immediate consumption are excluded and taxed at the applicable higher rate.)

March 1: Chicago Changed the Way It Taxes Alcohol (But Only When Sold “To-Go”)

This one makes me insane.

Until this year, Chicago imposed its liquor tax on a per-gallon basis, generally collected upstream by the distributor or wholesaler.

Effective March 1, 2026, Chicago replaced that system for alcohol sold for off-premises consumption with a tax equal to 1.5% of the retail purchase price.

For a straightforward package-liquor store, this is relatively easy to understand. If you sell someone a $20 bottle of wine to take home, you collect 30-cents of Chicago liquor tax, in addition to the other applicable sales taxes (of which there are plenty).

Retailers with active Chicago Package Goods licenses are required to collect the tax at the point of sale, remit it monthly to the Chicago Department of Finance by the 15th of the following month, and file an annual return through Chicago Business Direct.

But bars & restaurants are different from retailers.

Alcohol sold for on-premises consumption remains subject to the old per-gallon tax, collected through distributors (not the end-user aka retail purchaser).

Which raises a question that should be obvious to anyone who has ever operated a restaurant, brewery, wine bar, hotel, or other business that sells alcohol both ways:

How exactly is the business supposed to know which tax treatment applies to the alcohol when it buys it?

The City’s own FAQ tells distributors and wholesalers to stop charging the per-gallon tax on alcohol delivered to Package Goods license holders. But it also says:

“Only alcoholic beverages to be sold for on premises consumption should continue to be taxed on a per-gallon basis.”

Imagine a restaurant buys a case containing 12 identical bottles of Pinot Noir (my personal favorite, in case any particularly kind and generous readers were wondering). During the week, it opens eight bottles for customers dining at the restaurant and sells four unopened bottles to customers to take home.

The eight dine-in bottles are subject to the old gallonage-tax system, charged by the distributor to the restaurant (a cost to be passed on to end-users via the bottle price).

The four take-home bottles are subject to the new 1.5% retail-price tax, charged directly to the end-user by the restaurant as a tax which then will be reported and remitted to the City).

But at the time the restaurant bought the case, they were all the same bottles. Now you’ve got some that are taxed by the distributor based on volume and strength, and others taxed by the retailer based on price.

This isn’t merely a theoretical concern. Chicago alcohol-law firm Christopoulos Law Group has cautioned that the change affects retailers’ pricing, POS systems, tax reporting and compliance procedures. The Illinois Hotel & Lodging Association circulated the City’s FAQ to its members as well — and hotels are an especially good example of businesses that can have restaurants, bars, room service, minibars and package sales operating under the same roof.

Is tax treatment determined by:

1. the seller’s license/category,
2. how the inventory was purchased from the distributor,
3. whether the container is opened,
4. the customer’s stated intent at checkout,
5. where the customer actually consumes it, or
6. some combination of those?

The City’s FAQ is remarkably terse considering those possibilities.

They did provide a transition rule for inventory already on hand March 1: retailers take a credit against the new tax for Chicago gallonage tax previously paid on that inventory, and they must maintain inventory records supporting the credit (similar to how the bag tax was initially handled when it was implemented, to account for everything that was purchased prior to the new tax).

But the larger question remains: for businesses legitimately selling alcohol for both on- and off-premises consumption, the new rules appear to require the business — and potentially its distributor — to know the eventual sales channel of its inventory.

Look, I support taxation as a public-policy tool. But it’s gotta be something small business owners can actually implement, not like the cray-cray ones like this.

If the City has published detailed guidance explaining exactly how mixed-use businesses are supposed to track and document this, please send it my way… because I haven’t found it yet.

What businesses should do: If you sell any alcohol for off-premises consumption, confirm that your POS is properly identifying those sales and collecting the new 1.5% tax. If you sell alcohol both on- and off-premises, talk to your distributor and accountant or bookkeeper about how purchases are being classified and how you are documenting the two types of sales. Definitely don’t assume your POS, distributor, or accounting system handled this automatically. I can say from personal experience that this is not just unlikely, but probably impossible.

And remember that this affects your pricing; one tax is paid by the business to the distributor and needs to be wrapped into the retail price of the bottle; the other tax is charged by the business to the customer, but then has to be remitted to the City (and is no small feat to track and file), so that extra work needs to be taken into account as well when pricing.

Sigh again. (Wonder why accounting costs are going up? Just one of many reasons.)

August 1: Sales Tax Went Up Throughout the Chicago Region

As of August 1, 2026, the Northern Illinois Transit Authority — formerly the Regional Transportation Authority, or RTA — increased its occupation and use tax by 0.25%. The increase applies throughout Cook, DuPage, Kane, Lake, McHenry and Will counties.

For ordinary general-merchandise sales in Chicago, this increased the combined sales-tax rate from 10.25% to 10.50%, making us almost the highest in the country, especially considering that restaurant meals have Chicago’s separate restaurant tax layered on top, and establishments in the MPEA district have yet another tax. Alcohol now has the separate liquor-tax issue we’re discussing. And we also have a state income tax, unlike some of the other high-sales-tax cities.

(To clarify, this isn’t technically a City of Chicago sales-tax increase. The additional 0.25% comes from NITA, one of several taxing authorities whose taxes combine to create the rate customers eventually pay at the register.)

From the perspective of a retailer who needs the correct number programmed into a POS system, however, you probably don’t care about the details. The important thing to know is that the rate changed August 1st.

The NITA increase doesn’t apply only to ordinary retail merchandise. IDOR says it also applies to qualifying groceries, drugs and medical appliances, titled property, cannabis, and aviation fuel (not that this likely applies to anyone reading my blog), although those items don’t share the same overall combined tax rate. Again, the best place to figure out what to charge for which type of tax (or if a consumer, what you should be paying), is the Illinois Department of Revenue Tax Rate Finder.

What businesses should do: Check your August transactions and make sure your POS or sales platform began using the new rate on August 1. If it didn’t, fix it now and calculate the tax you should have collected since the effective date. Remember that the business generally owes the correct tax whether or not it actually collected enough from its customers.

While you’re at it, make sure you don’t have any random items on the “Back to School Sales Tax Holiday” list from IDOR that you’re selling Aug 7-16th. I complain to my state rep about this one every year. How do they expect small business owners to charge or not charge sales tax on an item-by-item basis? Make sure those protractors, lunch boxes and chalk are tracked properly, because “The sales tax rate that must be used during the holiday period is the rate currently in effect on the date of the holiday minus 5%.” Honestly?

One More 2026 Change for Businesses Selling Remotely to Illinois

There is another sales-tax change worth mentioning if you sell to customers outside your physical location, and some of them are based in our fair state of Illinois. And this one’s actually good news for small businesses.

Effective January 1, 2026, Illinois eliminated the old 200-transaction threshold portion of its rules to determine when remote retailers and marketplace facilitators are required to collect Illinois destination-based sales tax (a concept known as nexus), but they kept the economic nexus rules. An out-of-state remote retailer without physical presence in Illinois has economic nexus when it has: $100,000 or more in cumulative gross receipts from sales of tangible personal property to Illinois purchasers during the applicable preceding 12-month lookback period.

This change reduces the number of small remote sellers required to collect Illinois tax. Someone selling 250 $20 widgets into Illinois used to trigger nexus despite having only $5,000 of Illinois sales.

As before, if you make online or other destination-based sales to Illinois, it’s worth confirming that your sales-tax calculations are applying the current sourcing rules correctly.

By the way, an indication of how seriously IDOR wants businesses to get the location right: for certain destination sales where the taxpayer fails to provide enough information to determine the proper location, IDOR says it can assess tax on those receipts at a 15% rate. So that’s a dang good incentive to get the address right.

So What Should You Do?

If any of these changes apply to your business, I recommend reviewing your systems now rather than waiting until your next sales-tax return reconciliation — or, worse, an audit — to discover a problem.

Specifically:

1. Check the sales-tax rates programmed into your POS system. If you’re in the six-county NITA region, make sure the August 1 increase was implemented.
2. If you sell groceries, verify your local grocery-tax rate using the IDOR Tax Rate Finder.
3. If you sell alcohol for off-premises consumption in Chicago, confirm that you’re collecting the new 1.5% liquor tax.
4. If you sell alcohol both on- and off-premises, determine how you’re distinguishing and documenting those sales and how your distributor is treating the inventory.
5. If you make destination-based sales, review the 2026 Illinois sourcing changes.
6. Pull a few actual customer receipts. Don’t just look at the settings screen in your software. Calculate the tax independently and make sure the amount the customer is actually being charged is correct.

That last step is one I strongly recommend. I’ve seen plenty of situations over the years where everyone assumed a tax change had been implemented correctly because someone updated something somewhere in the software. Just walk up to the front counter and buy something. The receipt is where you find out whether it worked right or not.

Sales tax has always been one of those areas where small businesses are expected to act as unpaid tax collectors for multiple layers of government, while somehow keeping track of which agency changed which rate, on which product, in which jurisdiction, effective on which date.

This year isn’t making that job any easier for our Chicago clients and small business friends.

But correcting a sales-tax problem shortly after it happens is generally a whole lot less painful than discovering months or years later that you’ve been collecting the wrong amount all along.
