How SLTax360 Files Delaware Surplus Lines Taxes

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

Each Delaware transaction we file is itemized into its components: surplus lines tax (3%). 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 Delaware filings are submitted: SLTax360 keeps the Delaware rates, rules, deadlines and reports, and prepares each filing for submission through your own Delaware portal account, either by your team or by ours on a supported plan. There is no direct electronic filing integration for Delaware today, and we would rather say so than call it automated. You keep your own Delaware licence and portal login either way.

Whether you're an MGA filing a handful of Delaware 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 Delaware calculation (no signup required).
