Illinois Requirements

RequirementDetails
Commercial-building mine subsidence coverageIn non-exempt counties, included at a separately stated premium unless waived in writing; in counties exempted under §807.1, made available on policyholder request. For policies issued or renewed on or after January 1, 2027, no deductible or retention applies. 1,3,4

What to Watch for in Illinois

  • Check for Mine Subsidence Coverage

    The automatic inclusion rule applies only where the county is not exempt under §807.1; in an exempt county the insurer must make mine subsidence coverage available if the policyholder requests it. The Mine Subsidence Insurance Fund maintains the exempt and non-exempt county list, so ask your broker to confirm the insured building’s county status and whether the quote reflects a request or written waiver. 3,2

  • Track the 2027 Deductible Change

    Effective January 1, 2027, policies issued or renewed on or after that date may not apply a deductible or retention to mine subsidence damage. If your renewal crosses that date, ask the insurer to show the applicable endorsement and deductible treatment in writing. 1,4

  • Confirm the Policy Limit

    The statute requires the coverage component but does not set the commercial building’s full policy limit in the cited section. Ask for the mine subsidence limit and its stated premium on the actual quote. 1

  • Compare the Actual Commercial Form

    The Illinois Department of Insurance says commercial property, flood, and earthquake rates and rules do not need to be filed in the state. Ask your broker to explain the terms in your quote and provide the form and endorsements you would buy. 2

Surplus-lines tax and stamping office

Reported tax rate: 3.5% of taxable premium plus a 0.04% stamping fee; separate 1% fire marshal tax on taxable fire premium When Illinois is the insured’s home state, the broker reports and remits a 3.5% tax on gross taxable surplus-line premium less returned taxable premium. The separate SLAI stamping fee is 0.04% for policies effective on or after January 1, 2023; a 1% fire marshal tax also applies to taxable fire premium. 9,8,12,13,10

Surplus Line Association of Illinois

  • Illinois guaranty fund limits: For covered claims against a member insurer, the Illinois Insurance Guaranty Fund generally caps its obligation at $500,000 per claim; workers’ compensation claims are excepted from that dollar cap. This fund does not protect policies issued by nonadmitted surplus-lines insurers. The net-worth exclusions apply to covered claims against member insurers. 10
  • Illinois FAIR Plan: If you cannot obtain basic property coverage in the voluntary market, the Illinois FAIR Plan offers a residual-market option for eligible property. Check its current eligibility and coverage limits before relying on it for a commercial location. 11

Providers With Documented State Licenses

These providers publish a national listing for Commercial property; the state records document licenses for the entities and roles shown below. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Illinois. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

  • ERGO NEXT InsuranceNext First Insurance Agency, Inc.Insurance producer · checked 2026-09-28ERGO NEXT’s current license table lists Next First Insurance Agency, Inc. in 50 jurisdictions, including Washington, DC; New York is excluded because its table rows name Next Insurance Services and AP Intego, not Next First. The table is company-reported; it does not establish product availability or provide state-regulator verification for each entry. 18
  • RisklyticsRisklytics, Inc.Insurance producer · checked 2026-09-28Risklytics’ licensing page lists its Massachusetts resident agency license plus state license records in Arizona, Colorado, Illinois, Indiana, New Jersey, Ohio, Texas and Washington; it identifies the NPN record date as September 10, 2026. This list is company-published and not a product availability map. 19
  • TechInsuranceSpecialty Program Group LLCInsurance producer · checked 2026-09-28TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. 20
  • VouchVouch Specialty Insurance Services, LLCInsurance producer, Surplus-lines broker · checked 2026-09-28Vouch’s licenses page, effective January 16, 2025, lists producer licenses in all 50 states and DC. Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. 21
