Why We Built Residance
For globally mobile individuals, tax residency is rarely accidental. It's the result of where time is spent, how often, and under which rules. And those rules are becoming less forgiving.
Residance was built to solve a very specific problem: helping high net worth individuals and their advisors maintain clarity and control over tax residency exposure — before thresholds are crossed, not after.
The Problem No One Enjoys Talking About
Tax residency rules are deceptively simple on the surface. Spend too many days in the wrong place, and you may trigger obligations you never intended to create.
In practice, it's far more complex.
States and countries are tightening enforcement. Audits increasingly rely on digital trails. Historical assumptions about flexibility, intent, or informality are being tested — and often rejected. For individuals who move frequently, the margin for error is shrinking.
Yet most people still track their days using spreadsheets, calendar guesswork, or fragmented location histories. These methods are fragile. They fail quietly. And they tend to break at exactly the moment precision matters most.
Why Now
The landscape has changed.
High-tax jurisdictions are under pressure to increase revenue, and residency enforcement has become a reliable lever. In the U.S., states like California and New York continue to scrutinize physical presence with greater sophistication. Internationally, governments are aligning data sources and closing loopholes that once provided ambiguity.
At the same time, lives have become more mobile. Private aviation, remote work, multiple residences, and flexible schedules make it easier than ever to cross borders — and just as easy to cross a line without realizing it.
This combination — stricter enforcement and increased mobility — creates risk. Not theoretical risk, but operational risk that compounds quietly over time.
What Was Missing
We couldn't find a tool that treated residency tracking with the seriousness it deserves.
Most travel apps focus on memories. Most location tools focus on convenience. Most tax tools assume static lives.
Residance is different. It's designed specifically for people who need to stay under residency thresholds across multiple jurisdictions, while still living globally. It doesn't offer advice. It offers clarity — accurate, current, and always available.
The goal isn't to optimize aggressively or push limits. The goal is to know where you stand, at all times, so decisions are made intentionally.
Built for Precision and Discretion
Residance tracks presence passively and efficiently, with the option to plan ahead, adjust records, and export detailed reports when needed. It's built to be consulted quietly, not constantly.
For family offices, it provides a clean operational layer that supports broader tax and legal strategies. For individuals, it removes uncertainty from an area where uncertainty is costly.
Staying Ahead of the Line
Tax residency isn't something you want to think about after the fact. Once a threshold is crossed, the conversation changes — often permanently.
Residance exists to keep that conversation hypothetical.
If your life spans states or countries with complex residency rules, knowing your numbers isn't optional. It's foundational.
That's why we built Residance.
