Three Key Takeaways
- Illinois promised a complete franchise tax repeal by 2024, then reversed course mid-pandemic, leaving corporations in a compliance holding pattern that shows no sign of ending soon.
- For most small and mid-sized Illinois businesses, the actual dollar liability has been largely eliminated by a $10,000 exemption, but the annual filing obligation is fully intact, and missing it can cost you your good standing or trigger dissolution.
- Bills to accelerate the repeal are pending in the General Assembly but remain stalled in committee, which means this tax isn’t going away on any predictable timeline.
If you incorporated in Illinois more than a few years ago, you may have heard at some point that the franchise tax was being phased out. Maybe you stopped paying close attention to it. Maybe you assumed the annual filing wasn’t a priority anymore.
That assumption can get you into real trouble.
The Illinois franchise tax still exists. The annual report is still due. And the consequences of not filing are significant even when the dollar amount you owe is zero. This article covers what the tax is, what happened to the repeal, what’s still legally required today, and what you should be doing right now regardless of what the legislature does next.
What the Illinois Franchise Tax Actually Is
The Illinois franchise tax is an annual levy on corporations — both domestic (incorporated in Illinois) and foreign (incorporated elsewhere but authorized to do business here) — for the privilege of operating in the state. It is separate from your income tax return, calculated differently, filed with a different agency, and due on a different schedule.
The tax is based on paid-in capital, not on what your business earns. Paid-in capital is essentially the amount shareholders have contributed to the corporation in exchange for stock. For most corporations, that’s the sum of the capital stock and additional paid-in capital figures on the balance sheet — lines 22 and 23 on Schedule L of federal Form 1120 for C-corps. The annual rate is 0.1% of the Illinois-allocated portion of that capital, with a $25 minimum and a $2 million cap.
Two calculation methods are available: an allocation factor method that prorates capital based on Illinois property and business versus total everywhere figures, or election to pay on 100% of total paid-in capital.
One important structural note: this is primarily a C-corp and S-corp compliance obligation. LLCs taxed as partnerships are generally not subject to the franchise tax in the same way, though foreign corporations registered to do business in Illinois are also covered. S-corporations should also be aware of Illinois’s separate replacement tax obligation, which runs on a different calculation and filing track entirely.
Key Takeaway: The franchise tax isn’t tied to your profits. A restaurant or construction company with modest annual revenue but significant paid-in capital could owe more than the current exemption covers. Know your paid-in capital figure before assuming you owe nothing.
The Repeal That Wasn’t
In 2019, Illinois enacted legislation that would have eliminated the franchise tax entirely by 2024, with escalating exemptions along the way. It was a genuine commitment — or appeared to be one.
Two years later, in the early months of the pandemic, with state finances under pressure and a revenue hole to manage, the legislature reversed course. It “repealed the repeal,” scaling back the phase-out to a slow, incremental exemption increase with no statutory end date.
The exemption has risen over time: $1,000 in 2021, $5,000 in 2024, $10,000 starting in 2025. Each step has effectively zeroed out the actual dollar liability for the vast majority of small and mid-sized businesses — but the tax itself has never been repealed, and the annual filing requirement has never gone away.
Why does Illinois keep it on the books? The franchise tax has historically generated roughly $200 million annually for the state’s General Revenue Fund. Advocates for repeal , including the Illinois Policy Institute and the Taxpayers’ Federation of Illinois, have argued for years that most neighboring states have already eliminated similar levies and that the administrative compliance burden it imposes on businesses is wildly disproportionate to the revenue it generates. State budget officials have been unwilling to absorb that revenue loss all at once, particularly given Illinois’s chronically tight fiscal position.
Several bills in the current General Assembly have attempted to either accelerate the phase-out or eliminate the tax outright for domestic corporations. HB5526, introduced in February 2026, proposes raising the exemption to $100,000 in 2027 and eliminating the tax for domestic corporations entirely by 2028–2029. As of this writing, that bill and similar proposals remain in the Rules Committee with no clear path to a floor vote.
The practical implication: don’t plan around a repeal that hasn’t happened. Until legislation passes and is signed into law, the current rules govern.
The Compliance Trap: Why a $0 Tax Bill Doesn’t Mean $0 Paperwork
This is the part that catches businesses off guard, and it’s the most important thing in this article.
The franchise tax is calculated and reported as part of the Illinois corporate annual report, which is filed with the Secretary of State, not the Department of Revenue. These are separate agencies, separate filings, and separate obligations. Your income tax return filed with IDOR does not satisfy your annual report obligation with the Secretary of State, and vice versa.
The annual report is due before the first day of your corporation’s anniversary month (the month corresponding to your original incorporation date). The filing fee is $75, regardless of how much franchise tax you owe. If your paid-in capital is modest and your franchise tax calculation comes out to $0, you still owe the $75. You still have to do the calculation. You still have to file.
The consequences of not filing are not a tax penalty; they’re a corporate status problem:
- Loss of good standing with the Secretary of State
- Inability to enforce contracts in Illinois courts while not in good standing
- Potential personal liability exposure depending on corporate structure
- Administrative dissolution of the corporation if delinquency continues
A dissolved corporation doesn’t cease to exist in a vacuum — it creates complications with contracts, banking relationships, licensing, and any future sale or financing event. Reinstating a dissolved corporation is possible but involves back-filing, fees, and time you’d rather not spend.
The state’s own behavior reinforces how seriously it treats this: Illinois ran a dedicated franchise tax amnesty program from October 1 to November 15, 2025, specifically to address the volume of delinquent filers and bring corporations back into good standing. That program has now closed. Corporations that didn’t take advantage of it are still delinquent — and the penalties and interest that were waived during the amnesty window are now back on the table.
What You Should Be Doing Now
If you’re an Illinois corporation and you have any uncertainty about your current filing status, the following steps are worth working through before your next anniversary month arrives.
- Check your standing. The Illinois Secretary of State offers a business entity search at ilsos.gov that shows whether your corporation is currently in good standing. It takes two minutes and tells you immediately whether there’s a problem to address.
- Know your anniversary month. The annual report is due before the first day of the month corresponding to when your corporation was originally formed or authorized to do business in Illinois. If you don’t know that date, it’s on your original articles of incorporation or your Secretary of State registration documents. Our Illinois business tax deadlines guide can help you map this against your other filing obligations for the year.
- Calculate your paid-in capital. For most corporations, start with Schedule L of your federal Form 1120 — lines 22 and 23. That’s your capital stock and additional paid-in capital. If there have been equity transactions during the year, changes in paid-in capital may require filing an additional form (BCA 14.30) with your annual report.
- File even if you owe nothing. If the $10,000 exemption covers your liability, the franchise tax line on your annual report will show $0. You still owe the $75 filing fee, and the report still needs to be submitted.
- Don’t bank on pending legislation. HB5526 and related bills may eventually move — or they may not. The history of this tax is a history of promises made and reversed. Treat the current law as the operative framework until something changes.
If you’re behind on past filings, the amnesty window has closed, but getting current is still far better than remaining delinquent. The path back to good standing involves back-filing annual reports and paying applicable fees and penalties, and it’s something a CPA or business attorney can help you navigate efficiently.
Get Your Corporate Compliance Right
The Illinois franchise tax has become a compliance trap precisely because its financial burden is so low. Most business owners don’t owe anything, so they stop paying attention — and the administrative obligation quietly lapses.
At Ahlbeck & Cook, we work with Illinois corporations throughout the Chicago area — restaurant operators, franchise groups, construction companies, and growing businesses — and this is one of those issues that comes up more often than it should. Getting current is straightforward. Staying current is even easier. But finding out you’ve been dissolved when a contract, a loan, or a business sale is on the line is a problem worth avoiding entirely. If you’re also navigating Chicago’s local tax obligations alongside your corporate filings, our Chicago business taxes guide covers what’s due and when.
If you have questions about your franchise tax obligations, your corporate standing, or how your paid-in capital figures into the calculation, contact Ahlbeck & Cook. We can help you get clear on where you stand and make sure the filing doesn’t fall through the cracks again.
