CO| Effective April 1, 2026, all Colorado surplus lines policies, endorsements, audits, and cancellations with effective dates on or after January 1, 2022 that were not previously reported to the Colorado Division of Insurance must be filed through SLIP+ for States, and a 3% Colorado surplus lines tax will apply, though transactions effective between January 1, 2022 and December 31, 2024 will not incur the 0.175% SLIP+ transaction fee. The notice provides step-by-step examples for filing additional premium and return premium endorsements when original policies were reported in the legacy system or not reported at all, emphasizing that separate SLIP+ transactions are required for the original policy (often at 0 premium) and each unreported endorsement, with surplus lines tax but no SLIP+ fee applied in the specified date range.
It also notes that return premium filings exceeding the premium on the related new/renewal will trigger questions requiring coordination with the SLIP+ team and DORA to resolve tax inquiries and credits, and advises that additional training scenarios will be provided before the April 1, 2026 implementation.
