The cost of finding out a year late.

Expat tax mistakes are rarely about big decisions. They're about the small assumptions you carried over from home that quietly stopped being true.

You assumed your home-country tax treaty still covered your pension, until it didn't.

Your host country changed how foreign-source income is treated and your accountant only flagged it in March.

A double-tax treaty renegotiation altered the dividend withholding rate you'd been using to plan.

You crossed a residency threshold in your home country during a long visit and re-triggered worldwide tax.

The countries connected to your life, all in one view.

Heed connects your home country, host country, and anywhere your income or assets sit, then watches them for changes that affect you specifically.

Home-country residency tests

Centre of vital interests, habitual abode, day counts, and tie-breaker rules so you don't accidentally re-trigger tax residency.

Host-country regimes and reliefs

Impatriate regimes, foreign-source carve-outs, and remittance rules, including the changes that tighten them.

Double-tax treaties and withholding rates

Treaty renegotiations, MLI updates, and changes to withholding tax on dividends, interest, royalties and pensions.

Reporting obligations across borders

FATCA, CRS, foreign-account reporting, and the deadlines that move year to year.

What expats use Heed for.

Tracking your home country

Stay on top of rule changes back home so a visit, an inheritance, or a property sale doesn't catch you off guard.

Mastering your host country

Monitor the regime you moved under, and the proposals that could change it before your next renewal.

Coordinating with your advisor

Bring real-time intelligence to every meeting, so the conversation is about decisions, not catch-up.

We don't file your taxes. We make sure nothing surprises you.

Heed is a monitoring and intelligence platform. We don't prepare returns, give legal or tax advice, or replace your accountant. We give you and your advisors a head start on every rule change, threshold, and proposal that touches your setup, so the work you do together stays proactive instead of reactive.

Understand your obligations. Optimise your position.
