The cost of doing nothing
Sticking with the status quo isn't the easy option.
It may seem easier to keep managing notices the way you always have — but nothing about fees, accumulating interest, lost licenses, liens, and levies is easy. Unresolved notices don't sit still. They compound.
Penalties & interest
Every missed deadline adds fees and interest that quietly erode your bottom line.
Sequential notice backlog
When notices aren't addressed, agencies send duplicate and sequential notices — and the backlog spirals.
Liens & levies
Ignored balances escalate into liens and levies against your accounts and assets.
Lost licenses & standing
Unresolved compliance issues can put business licenses and good standing at risk.
Missed deadlines & lost files
Spreadsheets and email threads make it easy to lose a notice — and a deadline — entirely.
Wasted team hours
Skilled staff burn time hunting, re-keying, and chasing notices instead of doing higher-value work.
System Capabilities & Benefits
Everything your team needs to stay ahead of notices.
Collaboration
A team-based approach lets you share information, communicate, and resolve notices together — so everyone stays on the same page.
Boost Efficiency
Automated processes cut manual work by 50%. Centralize notices, POAs, and reports to reduce response times and improve your bottom line.
Stay Compliant
Automated routing, responses, and payments decrease response time and reduce notice volume — ensuring better compliance with regulators.
Peace of Mind
A clear, organized process for resolving notices reduces the risk of missed deadlines, lost files, and costly mistakes.

What the platform does
One operating system. Every core module.
From intake to resolution, NOTICENINJA covers the full lifecycle of tax and compliance work in a single, audit-ready platform. Start with the core system, then license the complete platform — or build yours from the modules and add-on features below.
The core system
Included with every subscriptionNotice tracking powered by Kata™ — every notice enters the system through Kata's agentic ingestion and flows into the notice workflow. The core system also includes the template letter library, SSO sign-on, and email integration.
