Built over years. Undone by one rule you never saw.
Years of planning can be undone by one buried amendment. Heed watches every jurisdiction your structure touches, at the depth your counsel would if they never slept.
The risks that don't make headlines.
The most expensive changes never make the news. They are the technical amendments, the anti-avoidance rules, the reporting expansions that quietly redefine what counts as compliant.
- A holding-company jurisdiction tightened economic substance rules and your structure no longer qualifies.
- An exit-tax expansion in your home country narrowed the window to relocate cleanly.
- Trust reporting rules expanded under DAC8 / CARF, and the new disclosures weren't on anyone's radar.
- A treaty MLI update changed the withholding rate on cross-border dividend flows from your investment company.

Coverage as broad and granular as your structure.
Heed maps the jurisdictions, entities and asset classes that matter to you, then watches them with the same depth your tax counsel would, if they had unlimited time.
Every jurisdiction in your structure
Multiple jurisdictions, including sub-national rates for US states, Swiss cantons, Canadian provinces and Spanish autonomies.
Entity, trust and holding rules
Substance, CFC, anti-hybrid, beneficial-ownership and trust reporting changes wherever your structures sit.
Exit taxes and relocation windows
Exit-tax proposals, lock-in periods and pre-arrival regimes that determine the cost of moving, or staying.
Asset-class-specific rules
Capital gains, dividends, crypto, real estate, art and collectibles, tracked at the level of detail that drives decisions.
What Heed changes for a structure like yours.
Defending the existing structure
