** Null Island is a companion application for individual and enterprise taxpayers who utilize Null Island’s tax compliance platform directly, through their advisors, or through their enterprise. ** USE CASES Tax Domicile | Tax Residency | Income Allocation | UBT EVIDENCE THAT COUNTS Not all applications are created equal. Some are built for casual tracking; Null Island is built for high‑stakes tax audits. With Null Island, you will walk into an audit with court-grade evidence designed to support defensible location records in high-stakes tax audits. If your evidence falls short, what’s at risk is back taxes, penalties, interest, and professional time that can run into tens or hundreds of thousands of dollars. That’s why several leading practitioners recommend Null Island: it’s designed to stand up to scrutiny and resolve audits quickly and confidently. ADMISSIBLE BY DESIGN. Admissible evidence does not happen by accident. Null Island is natively architected with audit scrutiny in mind, including in high-enforcement jurisdictions. Null Island’s platform has supported taxpayers and their advisors in several audits. WHY NULL ISLAND * Engineered for Completeness: Proprietary location algorithms are tuned for data completeness, reducing gaps that can weaken your evidence. * Evidence that agrees with itself: By bringing together travel records, expense receipts, toll records — and even selfies — alongside app location data, Null Island helps your residency story corroborate itself. * Modern under the hood: Simple on the surface. We use modern data infrastructure and intelligence behind the scenes so your day-to-day experience feels as straightforward as it should. * Case Ready: Outputs arrive in final, audit-ready form, so you or your advisor can review or submit them directly — without burning hours doing the rework.
