You find out at filing time. That is the problem.

Most people learn about a tax law change that affects them from their accountant, at filing time, often months after it took effect. By then the deadlines that would have let them act have passed. The information was public the day it changed. Nobody was watching it for them.

Why you hear about tax changes too late

Tax rules change constantly: residency thresholds, capital gains treatment, exit charges, and reporting obligations. Most of it is published in government gazettes, parliamentary records, and tax-authority bulletins that no individual reads. Advisers are engaged to file, not to monitor. So the gap between a change and the moment you learn about it is usually a full tax year.

What a tax early-warning system is

A tax early-warning system monitors tax law across the jurisdictions you are exposed to and alerts you the moment a change touches your situation, before it reaches your return. It is not a filing tool, an accounting package, or a calculator. It is the layer that tells you something moved while you can still act on it.

Who needs to watch tax law in more than one country

Anyone whose exposure crosses borders. Digital nomads and expats living across two or three jurisdictions a year, where a day count can flip residency. High-net-worth individuals with capital gains, crypto, or offshore structures, where one rule change can move a meaningful sum. Advisers and family offices who need a single workspace to watch every jurisdiction their clients touch.

How Heed works

1. Set your profile: tax residency, the countries you spend time in, your income types, and your asset classes.
2. Heed monitors primary legislation daily across the jurisdictions we cover, with AI-assisted extraction and human review before anything publishes.
3. You get an alert only when a change matches your specific exposure, not a generic bulletin that applies to nobody in particular.
4. The Residency Tracker and the Change Feed turn each alert into a decision, before a deadline instead of after it.

Common questions

How can I track international tax law changes in real time?

Heed tracks changes across the jurisdictions it covers and sends personalised alerts based on your residency and income types. Start with the free Tax Situation Roast, then the Signal tier from $12 a month begins the ongoing watch.

What is the 183-day rule and why does it matter?

Many countries treat you as tax resident once you spend 183 days there in a year, though the exact test varies by jurisdiction. Cross that line unaware and you can owe tax in a country you were only passing through. Heed's Residency Tracker counts your days per country and warns you before you approach a threshold.

Is Heed a replacement for my accountant?

No. Heed is the early-warning layer, not a filing service or a substitute for a qualified adviser. It tells you when something changes so you and your accountant can act in time, rather than discovering it at filing.

Start with the Roast

The fastest way to see this in practice is the Tax Situation Roast, a free, no-account read on where a jurisdiction's rules could catch you out. It is the front door. Signal, the entry tier, is where the continuous watch begins.
