State Comparison

Illinois LLC vs Maryland LLC (2026)

Written for owners based in Illinois.

Verdict: for most owners, form where the business is based

Maryland's $100 formation fee is below the $150 Illinois charges, but Form 1 costs $300 every April 15 against a $75 Illinois report, so the recurring bill is four times higher and year one is $400 against $225. The penalty is percentage-based rather than flat: a late Form 1 draws one tenth of one percent of the county assessment plus interest, and failing to file lets SDAT assess at twice the estimated value of your personal property. Bringing that entity into Illinois costs another $150.

A figure shown as "from" is the least the state can charge, not a price. Tennessee's report is $300 for up to six members and $50 for each member above six, its franchise tax is the greater of $100 or 0.25% of Tennessee net worth, Wyoming's report is the greater of $60 or $.0002 per dollar of in-state assets, Kentucky's entity tax is $175 up to $3 million of gross receipts and graduated above it, and New York's annual filing fee is graduated on New York source gross income. A total that contains one of those is shown as "from" for the same reason. Costs include every mandatory state charge: the filing fee, the report fee (annualised where a state files biennially), any state entity-level tax shown in its own row above, a one-time publication cost where the state publishes a rate for it, and any one-time registration charge a state requires before the LLC may trade. Two exclusions follow from that wording. Arizona and Nebraska require publication and publish no rate, so no newspaper cost is carried for either and their totals are not the whole cost. Alaska's $50 annual state business licence is a separate charge from the Secretary of State fees and is not carried here either. Annualising makes the 1, 3 and 5 year rows a cost of ownership rather than a payment schedule: a biennial state charges its whole report fee in the years it falls due and nothing in between. Entity-level taxes that only apply after a corporate election, or above an owner or income threshold, are excluded and flagged on the state's own cost page. New York's publication cost is carried at a $250 floor, roughly $200 of newspaper cost in a low-cost county plus the $50 Certificate of Publication fee. No county-clerk-designated New York City newspaper publishes a rate card, so the four-figure NYC estimates in wide circulation cannot be traced to a primary source and are not asserted here; budget for materially more than the floor if you file in a NYC county. Every fee was verified against the state's own fee schedule, statute, or revenue authority on 29 July 2026. Excludes registered agent and legal fees.

Filing Fees & Formation Costs

Illinois charges $150 to form an LLC, while Maryland charges $100. Maryland is $50 cheaper upfront. The cost that usually gets overlooked: if you form in Maryland but operate in Illinois, you must also register as a foreign LLC in Illinois (a $150 filing) and maintain a registered agent in Maryland (typically around $150 per year). That puts the realistic first-year cost of the Maryland route at roughly $400, versus $150 for simply forming in Illinois. Only one side of this comparison is knowable: Maryland publishes a standard turnaround (6 to 8 weeks), while Illinois publishes no standard processing time, so the two can't be ranked against each other on speed.

Taxes: Illinois vs Maryland

Both Illinois and Maryland levy a personal income tax on pass-through business income, and your LLC's profits will be taxed where you live and operate. Forming in Maryland doesn't change what an Illinois-based owner pays. Illinois levies a flat 4.95% personal income tax. Maryland LLCs owe a $300 minimum annual Personal Property Return fee.

Privacy & Asset Protection

Neither Illinois nor Maryland offers anonymous LLC formation: both states require owner or manager information on public filings. Maryland requires an authorized person on the Articles and files a Personal Property Return; management information is available on public filings. Business owners who prioritize privacy typically form a holding company in a state like Wyoming or New Mexico instead. Both states provide charging-order protection for LLC members, and for most small businesses the practical difference in asset protection between the two is minimal.

Annual Maintenance Costs

Illinois LLCs file an annual report ($75, due in the anniversary month), and Maryland LLCs file an annual report ($300, due April 15). If you form in Maryland while operating in Illinois, you maintain filings in both states, Maryland's report plus Illinois's equivalent for your foreign registration, and pay a Maryland registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Maryland route to roughly $525 a year, versus about $75 to keep a domestic Illinois LLC in good standing. The tax inside those totals: Maryland LLCs owe a $300 minimum annual Personal Property Return fee.

When Maryland Actually Makes Sense

Forming in Maryland makes sense in a few specific situations: your business genuinely operates in Maryland, with a real office, employees, or property there, or you're relocating to Maryland in the near future. For a typical small business based in Illinois, none of these usually apply. Registering a Maryland LLC to do business back home means $150 in Illinois foreign-registration fees, on top of Maryland's $100 formation fee, while Illinois's own annual report runs $75 a year and is due in the anniversary month. When in doubt, form where you actually do business.
