How to do it
Determine your business structure: sole proprietor, LLC, corporation, partnership
Register your business entity with the Iowa Secretary of State (for LLCs and corporations) - file online at sos.iowa.gov/business or in person/by mail
Obtain an EIN (Employer Identification Number) from the IRS at irs.gov if forming an entity, hiring employees, or operating as a partnership
Register with the Iowa Department of Revenue for a Retail Sales Tax Permit (also called Streamlined Sales Tax Registration) if you sell taxable goods or services in Iowa - register online at tax.iowa.gov; free to register; required to collect and remit Iowa sales tax
Register with Iowa Workforce Development for unemployment insurance if you have employees - iwd.iowa.gov
Check with your city or county for local business licenses - most Iowa cities require a local business license; county requirements vary; unincorporated areas may not require a county license
Check for industry-specific state licenses: contractors, health professionals, real estate agents, cosmetologists, engineers, and many others require state professional licenses through the Iowa Professional Licensing Bureau or specific state agencies
Renew entity biennial report with Secretary of State; renew local license per municipality schedule

County-specific variations apply
Iowa cities each independently administer local business licenses. Iowa does not have a statewide county-level business license requirement. Larger cities (Des Moines, Cedar Rapids, Davenport, Sioux City, Iowa City, Dubuque, Waterloo, Ames, West Des Moines) have their own business license portals and requirements. In unincorporated county areas, typically only state registration is required. Verify with your specific city or county before operating.
