MAJOR TRANSITION: Effective January 1, 2025, all policies and endorsements must be filed through the SLIP+ online system per HB 1119. Pre-2025 policies continue using legacy Colorado SLT system or paper forms. Simplified diligent search process effective January 2025: broker attestation waives 3-declination requirement. Multi-state allocation rule: 100% tax to Colorado if insured is headquartered in CO.

Filing Methods

  • SLIP+ Online Portal (2025+)
  • Colorado SLT System (pre-2025)
  • Paper Forms (pre-2025)

Filing Steps

  1. 1Policy Disclosure Required: "This contract is delivered as surplus line coverage under the Nonadmitted Insurance Act. The insurer issuing this contract is not licensed in Colorado but is an eligible nonadmitted insurer. There is no protection under the provisions of the Colorado Insurance Guaranty Association Act."
  2. 2Claims-Made Additional Disclosure: "This policy is a claims-made policy which provides liability coverage only if a claim is made during the policy Period or any applicable extended reporting Period."
  3. 3Non-Complying Auto Additional Disclosure: "This policy does not meet the statutory requirements of this State's financial responsibility laws. It does not provide liability coverage for bodily injury and property damage."
  4. 4Out-of-Country Coverage Additional Disclaimer: "This policy is issued by an insurance company that is not regulated by the Colorado Division of Insurance. The insurance company may not provide claims service and may not be subject to service of process in Colorado. If the insurance company becomes insolvent, insureds or claimants will not be eligible for protection under Colorado insurance law."
  5. 5Effective 1/1/2025: File all new/renewal policies through SLIP+ at https://slip.slasclearinghouse.com
  6. 6Pre-2025 policies: Continue using legacy Colorado SLT system or paper forms
  7. 7Diligent Search Simplified: Broker can attest in writing that they are familiar with the insurance market and risk cannot be placed in admitted market, OR accept producer affidavit - this WAIVES 3-declination documentation requirement
  8. 8Multi-State Allocation: If insured is headquartered in Colorado but has locations in other states, 100% of tax is payable to Colorado
  9. 9Monthly Reports: Report in month/year of policy effective date, not transaction date
  10. 10Quarterly Affidavits: Only required if business was submitted during that quarter
  11. 11Zero Business Filing: Required even for periods with no activity
  12. 12Form F Eligibility Application: Updated bi-annually on January 1 and July 1 - use appropriate version based on filing date
  13. 13Transaction Fee: 0.175% SLAS Clearinghouse fee applies to gross premium (premium plus taxable fees) for 2025+ policies, refundable pro-rata for returns/cancellations

Required Forms

  • SLIP+ Online Filing Portal (for policies effective 1/1/2025+)
  • Colorado Surplus Lines Tax System - SLT (for pre-2025 policies)
  • Independently Procured Insurance Premium Tax Report Form (for direct placements pre-2025)
  • Form F - Eligibility Application (bi-annual, voluntary)
  • Statement/Affidavit of Diligent Effort
  • Quarterly Affidavit (due 15th of month following quarter end, only if business submitted)

Common Issues to Avoid

  • Filing 2025+ policies through legacy system instead of SLIP+
  • Filing pre-2025 policies through SLIP+ (should use legacy SLT or paper)
  • Not filing monthly reports by 15th of each month
  • Missing March 1 annual deadline for statement and tax payment
  • Allocating tax to multiple states when insured is headquartered in Colorado (100% should go to CO)
  • Obtaining 3 declinations instead of using simplified broker attestation process
  • Not filing quarterly affidavits when business was submitted
  • Using wrong Form F version (must match Jan 1 or July 1 update period)
  • Confusion between independently procured (direct) vs surplus lines (broker) processes
  • Not including required policy disclosure language on contracts
  • Forgetting to affix disclosures to declaration page (copies must be maintained by broker)
  • Not accounting for 0.175% transaction fee on 2025+ policies

Helpful Tips

  • System transition cutoff is January 1, 2025: Policies effective on/after this date MUST use SLIP+
  • SLIP+ Single Account: One SLIP+ account needed per agent for all participating states
  • Simplified Diligent Search: Write attestation stating familiarity with market and inability to place in admitted market - saves time on 3-declination documentation
  • Colorado Headquarters = 100% Tax: No need to allocate if insured is headquartered in CO
  • Monthly Reporting: Report transactions in the month/year of policy effective date
  • Quarterly Affidavits: Only file if you submitted business that quarter - no need for zero business affidavits
  • Form F Timing: Applications filed Jan 1-June 30 use Jan 1 version; July 1-Dec 31 use July 1 version
  • Eligibility List is Voluntary: Application and fees optional if company wishes to be included
  • Alien Insurers: If on NAIC Quarterly Listing, no filings required (but fee required for eligibility list)
  • Transaction Fee Refunds: 0.175% fee is refundable pro-rata for return premium and cancellations
  • SLAC Not Collecting Tax: Surplus Lines Association of Colorado is active but not gathering tax data on behalf of DOI
  • Electronic Filing Only: Colorado DOI only accepts electronic filing - no paper submissions

Important Notes

Independently procured insurance (direct placement) uses different form/process than surplus lines (broker placement). 0.175% SLAS transaction fee applies to 2025+ policies. No export list. Voluntary eligibility list with Form F bi-annual updates (Jan 1 and July 1). Colorado does not allow domestic surplus lines insurers. SLAC active but NOT collecting tax data.
