Choose your business structure
LLC, S-Corp, C-Corp, sole proprietorship, or partnership. LLCs are most common for small businesses — they offer liability protection without C-Corp complexity. Consult an accountant before choosing.
Register with the IA Secretary of State
File your business formation documents with the Iowa Secretary of State. LLC filing fees vary by state ($50-500). Most states allow online filing.
Get an EIN from the IRS
Apply for a free Employer Identification Number at irs.gov. You need this before opening a business bank account. Takes 5 minutes online — you get your EIN immediately.
Open a business bank account
Keep business and personal finances separate. Bring: EIN confirmation letter, articles of organization/incorporation, operating agreement, and government-issued ID. Most banks require an appointment.
Get a Sioux City business license
Most Sioux City businesses need a local business license or permit. Check the Sioux City city clerk or business licensing office. Fees vary by business type ($50-500+). Some businesses need state licenses too.
Register for state and local taxes
Register with Iowa's Department of Revenue for state income tax withholding, sales tax collection (if applicable), and unemployment insurance. Sioux City may have additional city business taxes.
Get required permits
Depending on your business type in Sioux City: health permits (food), building permits (construction), home occupation permits (home-based business), signage permits, fire safety permits. Check with Sioux City's permit office.
Get business insurance
At minimum: general liability ($500K-1M), professional liability if service-based, workers' comp if you have employees. Get 3 quotes. Budget $50-200/month for a small business.
Set up accounting
Choose: QuickBooks Online ($30/month), Wave (free), or FreshBooks ($17/month). Set up from day one — reconstructing a year of transactions at tax time is painful and expensive.
Establish a web presence
Claim your Google Business Profile (free). Set up a basic website. Register social media handles. For local businesses, Google Business Profile is more important than your website for being found.
Find a CPA familiar with your industry
Find a CPA in Sioux City who works with businesses like yours. They'll save you money on your first tax return and advise on quarterly estimated payments. Ask other local business owners for referrals.
Join the local chamber of commerce
The Sioux City Chamber of Commerce offers networking, referrals, and visibility. Membership typically runs $200-500/year for small businesses. Many also offer free business workshops.
Set up quarterly tax payments
If you expect to owe $1,000+ in taxes, you must make quarterly estimated payments (April 15, June 15, September 15, January 15). Underpayment penalties add up. Your CPA can calculate amounts.
