A better starting point

From uncertainty to informed professional judgment.

Tax Authority Navigator is being developed to help practitioners research complex questions, understand relevant exceptions and competing interpretations, and document their analysis. It is a research aid—not a substitute for independent professional review.

Research grounded in authority

Focus on relevant tax law and its application to the facts, with citations that practitioners can examine.

See the important exceptions

Surface missing facts, material limitations, and alternative interpretations that can change the conclusion.

Keep a useful workpaper

Turn research into a structured record that can be reviewed, qualified, and retained within a professional workflow.

Why we're building this

Built with a practitioner's perspective.

Throughout my career in tax practice, I've seen how often experienced professionals turn to forums and colleagues when an issue demands research. Those conversations can be useful, but a client's tax position deserves more than an unsupported opinion.

Our goal with Tax Authority Navigator is to make rigorous, practical, authority-supported research more accessible—while keeping professional judgment where it belongs: with the practitioner.
