Every LLC and corporation registered in Illinois pays an annual report fee that includes the Illinois franchise tax. It’s the kind of charge that surprises business owners who already have enough on their plate with federal and state income taxes. Here’s what matters right now: Illinois is phasing this tax out, but it’s not gone yet. You still have filing obligations through the transition period.
This article covers how the franchise tax actually works, who still owes it, what the phase-out timeline looks like, and what you should do to stay compliant without overpaying. We’ll walk through the exact numbers, deadlines, and exemption thresholds so you can handle this quickly and move on to running your business.
What Is the Illinois Franchise Tax and Who Pays It?
The Illinois franchise tax is a fee the state charges businesses for the privilege of being incorporated or authorized to operate in Illinois. You can think of it as the cost of maintaining the legal structure that shields your personal assets from business liabilities. It’s completely separate from your state income tax, and the state collects it alongside your annual report filing with the Illinois Secretary of State.
How the Tax Is Calculated
The franchise tax is based on your company’s paid-in capital, which is the total amount of money and property that shareholders or members have contributed to the business. Illinois applies a rate of 0.1% (one-tenth of one percent) to that figure. So if your corporation has $1 million in paid-in capital, the base franchise tax comes out to $1,000.
There’s a minimum payment to keep in mind, too. Even if your paid-in capital is very low, you’ll still owe at least $25 in franchise tax. And here’s where things trip people up: the tax isn’t calculated on revenue or profit. A business that lost money all year long can still owe franchise tax because the calculation looks at your capital structure, not your earnings. That distinction really matters for newer businesses that are still investing heavily and haven’t turned a profit yet.
The Illinois franchise tax is based on paid-in capital, not revenue or profit, so even businesses operating at a loss may owe this tax.
Which Entities Are Subject to This Tax
Not every business entity in Illinois owes the franchise tax. It specifically applies to corporations (both C-Corps and S-Corps) and LLCs that are organized in Illinois or registered to do business here as foreign entities. Sole proprietorships and general partnerships don’t owe it because they don’t file formation documents with the Secretary of State in the same way.
If you formed an LLC or incorporated in another state but you’re operating in Illinois, you’re still on the list. The state considers you a “foreign” entity authorized to transact business here, and that authorization carries the same franchise tax obligation. This catches quite a few business owners off guard, particularly those who incorporated in Delaware or Wyoming for liability reasons but run their actual operations out of the Chicagoland area. The bottom line is straightforward: if you filed paperwork with the Illinois Secretary of State to exist or operate as a business entity, you should assume the franchise tax applies to you until the phase-out fully takes effect.
The Phase-Out: How Illinois Is Eliminating the Franchise Tax
Here’s the good news: Illinois is getting rid of the franchise tax. The state passed legislation to phase it out gradually, which means your obligation shrinks each year until the tax disappears entirely. But “phasing out” isn’t the same as “already gone,” and the transition period still requires you to file correctly and pay attention to the changing thresholds.
Timeline and Exemption Thresholds
The phase-out kicked off with tax year 2020 and follows a staggered schedule that raises the exemption amount each year. In practical terms, if your paid-in capital falls below the exemption threshold for a given year, you owe $0 in Illinois franchise tax. You still need to file your annual report, though.
The exemption jumped significantly over the past few years. For tax year 2024, the first $5,000 of liability was exempt. According to the Illinois Department of Revenue, the franchise tax is fully eliminated for tax years ending on or after January 1, 2024, with the final returns due in 2025. That said, if you have an outstanding balance from a prior year or you filed late, you could still owe money. Don’t assume you’re in the clear without checking your account with the Secretary of State first.
The Illinois franchise tax is fully eliminated for tax years ending on or after January 1, 2024, but businesses with outstanding balances or late filings from prior years may still owe.
If your entity’s annual report period straddles the cutoff, the timing of your fiscal year-end determines which rules apply. Calendar-year filers are in the clear going forward, but fiscal-year filers with periods ending before January 1, 2024, should double-check their final obligation.
Illinois Franchise Tax vs. Other State Business Taxes
It helps to see how the Illinois franchise tax compares to similar charges in nearby states and beyond. Some states never had one, while others still impose them with no end date in sight. Here’s a quick comparison so you can put Illinois’s phase-out in context:
| State | Tax Type | Basis | Status |
|---|---|---|---|
| Illinois | Franchise Tax | Paid-in capital | Fully phased out (2024) |
| California | Franchise Tax | Net income ($800 minimum) | Active |
| Delaware | Franchise Tax | Authorized shares or assumed par value | Active |
| Texas | Franchise (Margin) Tax | Revenue-based margin | Active |
| Indiana | None | N/A | No franchise tax |
The takeaway? Illinois business owners are catching a real break. States like California and Delaware continue to collect franchise taxes with no phase-out on the horizon, and those obligations can be far steeper. California’s $800 minimum alone exceeds what most small Illinois entities ever owed. If you operate across multiple states, though, keep in mind that eliminating the Illinois franchise tax doesn’t free you from similar charges elsewhere. Each state has its own rules, and keeping track of all of them is where things get complicated fast.
How to Stay Compliant and Reduce Your Tax Burden
The Illinois franchise tax may be on its way out, but your filing obligations are still very much alive. Between annual reports, state income taxes, and federal returns, there’s a lot that requires your attention each year. The good news? There’s also a lot of room to save money when you approach things with the right plan in place.
Filing Requirements and Deadlines
Your annual report with the Illinois Secretary of State is still required whether or not you owe franchise tax. The filing fee is $75 for both domestic corporations and LLCs. If you miss the deadline, your entity can fall into “not in good standing” status, which creates real problems when you’re trying to secure financing, sign contracts, or sell your business. Ignore it long enough, and the state can administratively dissolve your entity altogether.
On the income tax side, Illinois follows federal due dates. C-Corps file by April 15 (or the 15th day of the fourth month after their fiscal year ends), while S-Corps and partnerships file by March 15. Extensions give you more time to file, but they don’t give you more time to pay. If you owe money and you’re late, penalties and interest start adding up right away. The IRS business tax page is a solid reference for keeping federal deadlines organized alongside your Illinois obligations.
Illinois Business Tax Compliance Step By Step
Here’s a step-by-step process you can follow each year to stay on top of your Illinois business tax compliance:
- Confirm your entity status: Log into the Illinois Secretary of State’s business database and verify that your entity is active and in good standing before tax season kicks off.
- File your annual report on time: Note the anniversary month of your incorporation or LLC formation. That’s when your report is due, not the calendar year-end.
- Reconcile paid-in capital records: Even though the franchise tax is phased out going forward, check that you don’t have an outstanding liability from prior years that could trigger penalties.
- Prepare and file federal and state income tax returns: Gather your financial statements, identify all eligible deductions and credits, and file by the applicable deadline or request an extension with a payment estimate.
- Review estimated tax payments: If your business expects to owe more than $500 in Illinois income tax, you’re required to make quarterly estimated payments to avoid underpayment penalties.
Sticking to these steps keeps you out of trouble and makes sure you’re not leaving deductions on the table.

FAQs
Do I still need to file an annual report in Illinois if I no longer owe franchise tax?
Yes, every LLC and corporation registered in Illinois must file an annual report with the Secretary of State regardless of whether any franchise tax is due. Failing to file can result in your entity losing good standing status or being administratively dissolved.
Can I get a refund for Illinois franchise tax I overpaid in prior years?
If you overpaid before the phase-out took full effect, you may be eligible to request a refund or credit by contacting the Illinois Secretary of State’s office. It is worth reviewing your past filings to confirm whether any overpayment occurred.
How do I know if my business still has an outstanding Illinois franchise tax balance?
You can check your entity’s status and any remaining balances through the Illinois Secretary of State’s online business database. Unpaid amounts from tax years before the full elimination can still accrue penalties, so verifying your account is important.
Are sole proprietors or freelancers in Illinois subject to any franchise-style business tax?
No, sole proprietorships and general partnerships are not required to pay this type of tax because they do not file formal formation documents with the state. Only entities like LLCs and corporations that register with the Secretary of State have this obligation.
What happens if my Illinois LLC or corporation falls out of good standing?
Losing good standing can prevent you from entering contracts, obtaining business loans, or completing a sale of your company. If the issue goes unresolved for an extended period, the state can involuntarily dissolve your entity, which creates additional legal and financial complications.
