Steps
Complete the OPTins implementation and registration forms (published on content.naic.org) and submit them to have an OPTins account provisioned.
Log in to the OPTins web application and select the applicable participating state and filing type (premium tax, surplus lines tax, or other state-specific filing).
Upload the required state-specific filing form or data and enter the applicable tax and fee amounts as prompted.
Submit the filing, which routes the associated fees to the state via Electronic Funds Transfer (EFT) rather than a separate check or wire.
Retain the OPTins confirmation and submission record for compliance purposes, since it is the system of record for that state's electronic filing.
Known gotchas
OPTins is a web application/portal, not a public REST API — there is no documented programmatic endpoint for third-party software to submit filings directly; automation is generally limited to preparing data for a scripted or manual browser-based upload.
OPTins only covers states that participate in the program — confirm the specific state and filing type you need is currently listed as an OPTins participant before assuming this route applies, since not every state uses it for every filing.
