Frequently Asked Questions

You can register your business name via the Missouri Secretary of State (SOS) Business Division portal (click here to visit).

Useful information:

– You can find information about the fees and the required filing forms here.

– Just like other states, Missouri has a requirement for the registration of a fictitious business title if you’re not operating the company under your own name.

– If you don’t want to deal with an online registration, it’s also possible to submit the required forms by mail to the Missouri Secretary of State office address (listed above).

To register your business name, you’ll need to go through the following steps:

– Fill out all of the forms and submit them via the Missouri Secretary of State online portal.

– Provide the address of the business and the address of the business owner (these can be changed when you apply for the renewal of your business registration).

– Pay the fees and provide evidence these have been addressed.

– If you are not ready to register your company yet, you can reserve a name of preference for a period of 60 days.

Once you go through with the process, your name registration will remain valid for a period of five years.

As far as fictitious names in Missouri are concerned, there’s no requirement for uniqueness. Numerous entities could be operating under the same fictitious names.

When it comes to business names, however, you need to choose a title that’s distinguishable from all of the other registered business names.

Keep in mind that a Missouri name filing does not prevent a national entity from another state from pursuing legal action against you due to the fact that your title is the same. Hence, you should be very careful about business title selection and you should do sufficient research.

It’s always best to opt for a title that’s distinctive and original. You’ll be free from legal worries and you’ll also benefit from enhanced marketing opportunities this way.
