SLTax360 helps insurance agencies, MGAs and wholesale brokers keep multi-state surplus lines compliance in one place: correct tax math, every deadline, and every filed report and confirmation, with direct electronic filing wherever a state allows it.
From solving one broker's problem to nationwide compliance automation
In 2020, we started working with a single insurance broker who was drowning in compliance paperwork. Their legacy system had no API connectivity to state tax authorities. Every surplus lines filing was a manual process: rekeying data, tracking deadlines on spreadsheets, and hoping nothing slipped through the cracks.
We knew there had to be a better way.
So we built a tool that could read invoices directly from email attachments. It extracted policy data, coverage codes, and tax amounts using AI and optical character recognition. This was 2020, well before AI-powered document processing became mainstream. We weren't chasing a trend. We were solving a real problem for a real client.
That tool worked. It eliminated hours of manual data entry and virtually ended filing errors. And it raised an obvious question: if one broker needed this, how many others were stuck with the same outdated workflows?
The answer was: a lot of them.
We began offering the same capabilities to other managing general agents at competitive pricing, not as a massive enterprise deployment but as a practical, affordable platform that mid-size agencies could actually adopt. We added direct API integrations to state tax systems, removing the last manual step in the filing chain.
In 2023, we integrated modern AI technologies including GPT-4 into our document processing pipeline. Processing accuracy increased, costs dropped, and we were able to handle growing volume while passing those savings directly to our clients.
Today the platform covers all 50 states and the District of Columbia: rates, rules, deadlines, filed reports and payment tracking in one place, with filings transmitted directly to the state in more than 25 of them and prepared for portal submission everywhere else. It has been running a filing bureau's daily operation in production since 2024, covering more than 17,000+ filings and over $44M+ in premium. What started as a fix for one broker's pain point has become a full compliance platform, but we've never lost sight of why we started: making compliance simpler, faster, and cheaper for the people who actually have to do it.
Surplus lines tax compliance shouldn't be this hard.
51 jurisdictions, each with different rates, fees, deadlines, and reporting requirements. Keeping up manually is a full-time job.
Rekeying invoice data into state portals is slow, error-prone, and expensive. One typo can trigger audit flags.
Software that predates state API programs means no automation, no real-time confirmation, and no way to scale.
Missed filings mean penalties, audit risk, and reputation damage. There's no margin for error in compliance work.
Traditional service bureaus charge premium rates that put real pressure on mid-size budgets. Mid-size agencies deserve better options.
