Frequently Asked Questions

Does NOTICENINJA automatically assign notices?

Yes, NOTICENINJA is corporate tax notice compliance software that automates key workflows including notice assignments. The platform employs a rule-based system that can manage multiple level rules and ensure notices are directed to the appropriate stakeholder. As a result, you’ll never have to worry about notices being misdirected or slipping between the cracks.

Can it generate reports to show how things are going?

Yes, NOTICENINJA’s dashboards and advanced reporting capabilities will give you a bird’s eye view of the tax notices your organization receives – and deep insight into liabilities and opportunities. With NOTICENINJA’s tax notice management and resolution software, you can accurately assess where notices are coming from and how much time and money you expend per jurisdiction. That insight will allow you to get to the root cause of your tax compliance challenges, so you can reduce notice volume and better manage workloads.

Does your company offer services to help with backlogs?

Yes, we do.

Backlogs are common and can create a vicious cycle. When organizations have a backlog of notices to respond to – and lack the manpower to tackle them – it’s easy for notices to fall by the wayside. When notices aren’t addressed promptly, issuing agencies will send duplicate or sequential notices, which exacerbates the existing backlog.

If your organization is struggling, NOTICENINJA can help close out your backlog of notices – and empower you to remain backlog-free. The platform’s automated workflows and due date tracking and document management functionalities enable organizations to resolve notices within 30 days, eliminating the cycle of follow-up notices and growing backlogs.

Can NOTICENINJA track agency agents (Contacts) by phone and email?

Yes, NOTICENINJA’s tax resolution software has a module that allows you to track and manage all agency contacts and other related information. Within the module, you can view contacts’ addresses, links and login information, which eases traditional change management challenges. Users can also include notes about specific jurisdictions and contacts to streamline notice resolution.
