Illinois LLC Business Licenses — Step 7 of 8
Illinois has no general statewide business license — but Chicago and other municipalities have their own requirements, and most businesses selling goods or services need a state sales tax account.
Illinois has no blanket statewide general business license. Check the actual municipality, business category and professional board for license requirements, fees and renewal periods. Use the current destination-specific tax lookup rather than treating Chicago’s example rate or a license-cost range as universal. Beginning January1,2026, remote-retailer nexus uses $100,000 or more of relevant Illinois receipts in the preceding12-month period, evaluated quarterly; the200-transaction test is removed.

Illinois's Licensing Landscape
Illinois leaves most day-to-day licensing decisions to cities and counties, with a few statewide requirements layered on top:
- No general statewide business license — Illinois doesn't require every LLC to hold a basic statewide operating license.
- Check Chicago’s actual license category, fee schedule and renewal term; do not use a generic $500–$1,000 range for every business.
- Free sales tax account for taxable sales — register on MyTax Illinois for a Retailer's Occupation Tax number if you sell goods or taxable services.
- Regulated professions need state-level licensing — cosmetology, real estate, and private investigation are notable examples requiring an IDFPR (Illinois Department of Financial and Professional Regulation) license.
- No statewide contractor license — HVAC, plumbing, and electrical contractors are licensed at the municipal level, so requirements vary by city or county.

Getting Your Sales Tax Account
- Register through MyTax Illinois — no fee to obtain a Retailer's Occupation Tax number, which functions as your sales tax account.
- The general state sales-tax component is 6.25%; verify the current destination-specific local and special rates.
- Illinois uses destination-based sourcing for remote sales — you charge tax based on where your customer receives the product, not where your business is located.
- Remote sellers trigger nexus at $100,000 — revenue-only, since Illinois eliminated the 200-transaction threshold effective January 1, 2026. Marketplace sales are generally excluded from your own threshold calculation when the marketplace collects and remits on your behalf.
- Groceries are now exempt from state sales tax — effective January 1, 2026, though individual municipalities may adopt their own local 1% grocery tax.
Illinois's PPRT catches out-of-state founders off guardMulti-member Illinois LLCs owe a 1.5% Personal Property Replacement Tax that most other states don't have — it's separate from sales tax and separate from individual income tax. We cover the full details, with a calculator, in Step 8.
