Introduction
For most business owners, the better choice is the state where you live and run your business. Delaware has real advantages for larger businesses seeking outside investment, but Illinois is often the more practical and cost-effective option if you're based there. Here's what actually separates the two.
Why Delaware is so popular for incorporation
Delaware is the most popular state for business formation in the U.S. because of its flexible corporate laws, investor-friendly protections, and a dedicated court system — the Court of Chancery — that handles business disputes without a jury. More than two-thirds of Fortune 500 businesses are incorporated there, and more than 93% of Initial Public Offerings have historically been for businesses registered in Delaware.
Delaware also charges a flat annual franchise fee that doesn't vary with a business's income, which gives larger businesses predictable costs. Its corporate statutes give boards and shareholders more flexibility than most other states.
That said, most of these advantages matter most to businesses raising venture capital, planning an IPO, or managing complex investor relationships. For a small business or a single-member LLC, the Delaware premium rarely pays off.
Costs and filing times compared
The upfront costs and processing times differ between the two states, and those differences can affect how quickly you're up and running. Illinois is faster at the standard tier and costs more to file initially, while Delaware is cheaper to form but slower at the standard pace.
- Standard filing time: 5 weeks in Delaware, 3 weeks in Illinois
- State filing fee for an LLC: $90 in Delaware, $150 in Illinois
- Expedited filing time: 3 business days in Delaware, 1 business day in Illinois
- Expedited filing surcharge: $100 in both states
One cost that catches people off guard: if you form in Delaware but operate in Illinois, you'll need to register as a foreign LLC in Illinois anyway — which means paying Illinois's state fee on top of Delaware's. That double-filing cost erases most of the savings for small businesses.
Tax implications for Delaware vs. Illinois LLCs
Where you form your LLC affects what taxes you owe and to whom. Both states have distinct tax structures, and understanding them helps you avoid surprises at the end of the year.
Sales tax
Delaware has no state sales tax — one of only five states without one. Illinois has a state sales tax rate of 6.25% on most tangible goods, with local rates that can push the combined rate higher depending on where you operate. If your business sells physical products, this difference is worth factoring in.
Franchise tax and annual reports
Delaware LLCs pay an annual franchise tax of $300, due June 1 each year. Illinois LLCs file an annual report with a $75 fee. If you form in Delaware but operate in Illinois, you'll owe both — the Delaware franchise tax and the Illinois annual report fee — which adds to your ongoing compliance costs.
State income tax
Illinois has a flat personal income tax rate of 4.95% and a flat corporate income tax rate of 9.5%. Delaware has a graduated income tax structure. For pass-through entities like most LLCs, the income flows to the owner's personal return — so the state where you live and file your personal taxes is what matters most, not just where the LLC is formed.
Which state is right for your business?
It depends on what your business is and where you run it. For most small business owners and solo founders, forming in the state where you live and do business is the right call — it's simpler, cheaper, and avoids the foreign registration requirement.
Form in Delaware if you're planning to raise venture capital, bring on outside investors, or eventually pursue an IPO. Delaware's legal infrastructure and investor familiarity make it the standard for those paths. Many investors and law firms expect it.
Form in Illinois if you live and work there, you're running a small business or side venture, and you're not planning to raise institutional capital. You'll avoid double-filing fees, keep your compliance in one state, and deal with one set of annual requirements. For most Illinois-based entrepreneurs, that's the cleaner path.
A tax professional can help you figure out which structure makes the most sense for your specific situation, especially if you're weighing S Corporation election or multi-state operations.
FAQ
It depends on your goals. If you live and run your business in Illinois, forming there is usually the better choice — you avoid double-filing fees and keep compliance in one state. Delaware makes more sense if you're raising venture capital or planning an IPO, since investors and law firms are familiar with Delaware's legal structure.
To register an LLC in Illinois, you file Articles of Organization with the Illinois Secretary of State and pay the $150 state filing fee. You'll also need a registered agent with an Illinois address. Standard processing takes about 3 weeks, or 1 business day with the $100 expedited fee. After formation, you'll need an Employer Identification Number (EIN) from the IRS to open a business bank account and handle taxes.
Yes. You don't need to live in Delaware to form an LLC there. But if you operate your business in another state — like Illinois — you'll need to register as a foreign LLC in that state too, which means paying that state's filing fee on top of Delaware's. For most small businesses, that extra cost and paperwork makes forming in your home state the more practical option.
Yes, but only if you actually sell to customers in Delaware. Delaware has no state sales tax, which is a real advantage for businesses operating there. If your customers are in Illinois, you'll still owe Illinois sales tax regardless of where your LLC is formed. Sales tax is based on where the sale happens, not where the business is registered.
Delaware LLCs pay a $300 annual franchise tax due June 1. Illinois LLCs file an annual report with a $75 fee. If you form in Delaware but operate in Illinois, you'll owe both fees every year — $375 combined before any registered agent costs. For a small business, that ongoing difference adds up faster than most people expect.
