How much does it cost to register a business name in Iowa?

The name itself is free to search. Filing the entity is what costs money: $50 for an LLC and $50 for a corporation, then biennial report, $30 online (llc) / $45 (corp), due april 1 of odd-numbered years.

How many new businesses start in Iowa each year?

The Census Bureau counted 37,944 business applications in the twelve months to August 2026, +14.2% on the year before. Not every application becomes a registered entity, but each one is a name someone intends to use.

Does an Iowa registration protect my name in other states?

No. It protects the name inside Iowa's registry only. Nationwide protection comes from a federal trademark, which is why the checker runs the USPTO search alongside the Iowa lookup.

What does an Iowa LLC name have to end with?

One of the state's accepted designators — LLC, L.L.C., L.C. and Limited Liability Company. The checker searches the name with and without the suffix, because the suffix alone never makes a name distinguishable.

Can I reserve a business name in Iowa before I file?

Yes. The Iowa Secretary of State charges $10 to reserve a name for 120 days. A reserved name shows as taken to everyone else's search.

Iowa business name generator — every idea checked against Secretary of State records

Iowa is one of the cheapest states to run a small company from: a $50 formation and a $30 report every two years. Filings through Fast Track are accepted almost instantly, so the name search is the only real gate — and Iowa's registry treats 'Company' and 'Co.' as the same word when judging whether two names are distinguishable.

How to land a name that's actually available in Iowa

Start with the registry. Search the Iowa registry for the exact name; it's the check that decides whether you can file at all.
Then the two checks the state doesn't do. A federal trademark reaches across state lines, and the .com decides whether customers find you — both run here automatically.
Lock it in. Iowa will hold it for 120 days for $10. The system of record is the Iowa Secretary of State; confirm there before paying a filing fee.

Already have a name in mind?

You don't have to start from ideas — the same checker verifies a specific name. Enter the exact name you're considering and it's searched against the Iowa registry, federal trademark filings, and domain registrars in one pass.

Iowa naming rules: what the Iowa Secretary of State will and won't accept

Every Iowa filing is screened for a single thing before anything else: the name must be distinguishable upon the records of the Secretary of State. Swapping 'Inc.' for 'LLC', adding 'The', or changing a comma does not make a name distinguishable here. For an LLC the accepted endings are LLC, L.L.C., L.C. and Limited Liability Company; corporations take Corporation, Corp. and Incorporated.

A few words are gated. In Iowa that list includes Bank, Trust, Insurance, Cooperative and Engineer — using one implies a regulated activity and the filing will be held until the relevant regulator consents.

The fees are straightforward: forming an LLC costs $50, a corporation $50 and a name reservation is $10 and holds the name for 120 days. Fast track filing online is usually immediate.

After you file: Biennial report, $30 online (LLC) / $45 (corp), due April 1 of odd-numbered years. An entity that stops filing loses good standing, and with it the exclusive claim to its name.

As published by the Iowa Secretary of State, (515) 281-5204 — fee schedule. Fees change; confirm before filing.

Name ideas that fit Iowa — and clear its registry

The generator starts from what your business does and who it serves, then checks each idea against the Iowa registry, the federal trademark register and domain availability before it shows it to you.

When an idea clears, Iowa lets you hold it: a name reservation costs $10 and lasts 120 days — enough time to finish the paperwork without watching the name every morning.

Remember the suffix: an Iowa LLC name has to end in LLC, L.L.C. and L.C., and the generator appends it before checking so what you see is what you'd file.

How busy is Iowa right now?

In the year to August 2026, Iowa recorded 37,944 new business applications — +14.2% on the year before, the 38th-highest total of any state and 11.7 per 1,000 residents (ranked 48th per person). April was the busiest month with 4,281 applications, and Iowa accounts for 0.6% of all U.S. filings.

The busier the state, the more the obvious names are gone; the generator's job is to find the ones that are still open.

How Iowa decides whether a name is taken

Three things the Iowa Secretary of State looks at, and one it doesn't:

Status. Only entities in an active status hold their names. Dissolved, revoked and withdrawn registrations release the name — with the caveat that a very recent lapse can still be reinstated, which our result notes when it applies.
Distinguishability. Your name must differ from every active Iowa name by more than punctuation, spacing, capitalisation or the entity designator. Two names that read the same aloud are usually treated as the same name.
Designator. The recorded name of an LLC ends in an LLC designator and a corporation's in Inc., Corp. or an accepted equivalent; leave it off and the filing is returned.
Not trademarks. The registry never checks the USPTO. A name can be free in Iowa and still infringe a federal mark, so run both — the checker on this page does.

Naming rules, fees and reservation windows come from Iowa statute and change; treat the Iowa Secretary of State's current guidance as final before you file. This is a practical guide, not legal advice.

About the Iowa Secretary of State

The Iowa Secretary of State maintains Iowa's registry of corporations, LLCs, and other registered entities — it is the system of record for Iowa business names. Useful official resources:

Official Iowa business entity search — the state's own lookup.
Iowa Secretary of State — official website — filings, forms, fees, and contact details.

Confirming the result on the Iowa Secretary of State's site

Treat the checker as the fast filter and the state's own search as the final word. Once a name comes back clear here, open the Iowa entity search and type the name the way it will appear on the formation document — designator and all. Read down the list of matches rather than stopping at "no exact match": look at each record's status (only active ones block you) and at how close the spelling is, because Iowa rejects near-duplicates as well as duplicates. If the name is still clear, reserve it or file the same day; registrations are first-come, first-served and the registry moves daily.
