How SLTax360 Files Indiana Surplus Lines Taxes

Filing surplus lines tax in Indiana means navigating Indiana's specific submission channel, fee structure, and deadline rules. SLTax360 abstracts that away: we maintain the Indiana rate configuration in a versioned table and apply it automatically to every invoice you submit.

Each Indiana transaction we file is itemized into its components: surplus lines tax (2.5%). Your audit trail then shows exactly which line went where. Confirmations are retained, deadlines are tracked, and filings are reconciled against your invoice data.

How Indiana filings are submitted: Indiana does not offer an unattended machine channel, so the platform calculates the amounts and generates the state's required file (NAIC OPTins monthly batch) for submission through your own Indiana portal account. The confirmation is stored back against the filing. You keep your own Indiana licence and portal login either way.

Whether you're an MGA filing a handful of Indiana transactions per month or a wholesaler running hundreds, the amounts, the deadline and the paperwork are handled in one place. Want to verify the numbers yourself first? Run a free Indiana calculation (no signup required).
