Your quiet location log. Always running. Never uploading.
⊞ Get it on Microsoft StoreAggressive tax authorities are making it essential to be able to prove your domicile and tax residency. whereWUZi can help by logging your location every day.
State tax authorities have gotten far more aggressive about pursuing people they believe still owe them money, and the fights are landing squarely on the wealthy and the mobile. New York City has begun taxing nonresident owners of pied-a-terre apartments, and California lawmakers have floated a wealth tax aimed at billionaire residents. Attorneys who handle residency disputes report a steady rise in formal audits as remote work and multiple homes make it harder than ever to pin down where someone actually lives.
Proving where you actually spent your time is harder than most people expect. Memories fade, receipts get lost, and credit card statements only show where you spent money -- not where you slept. whereWUZi builds a dated, automatic record of your presence every day in the background, creating exactly the kind of contemporaneous documentation that can become an important piece of the puzzle in establishing domicile and tax residency.
