Running a website from Seneca: the Illinois rules
A website doesn’t need a special license, but the business behind it follows the same Illinois rules as any other.
- Illinois taxes general merchandise at a 6.25% state Retailers’ Occupation Tax rate, with a preferential 1% rate on qualifying drugs and medical appliances; municipalities and counties add local rates. Illinois Department of Revenue
- Illinois has no statewide general business license; cities and counties impose their own taxes and may require zoning permits, so the city or county clerk is the place to check. In Seneca, that means asking LaSalle County and the Village of Seneca. Official source
- Illinois splits the DBA filing: a sole proprietorship or general partnership registers the assumed business name with the county clerk, while a corporation, LLC or LLP registers an assumed name with the Secretary of State. Assumed Business Name Act, 805 ILCS 405
