US founders and Cyprus: what a move can't fix

If you are a US citizen or green-card holder, the honest answer is the one nobody selling a company wants to give: moving your business to Cyprus does not get you out of US tax. The United States taxes its people on worldwide income no matter where they live, and a whole apparatus of rules — controlled foreign corporations, GILTI, Form 5471 — is built precisely to follow profit into a foreign company you own. Cyprus can still earn its place in a US founder’s structure. But it does that as a complement to US compliance, not as a way around it, and starting from that truth saves a lot of expensive disappointment.

Cyprus optimises the non-US side of your affairs. It cannot switch off the US side.

Citizenship-based taxation is the fact everything else bends around

Most countries tax you on where you live. The United States taxes you on who you are. A US person stays inside the US system after relocating to Nicosia, to Dubai, or anywhere else — the passport, not the address, is the trigger. That single feature is why the usual offshore playbook does not translate: you cannot become a tax non-resident of the US by leaving it. Everything below follows from that.

CFC rules and GILTI reach into the company

When a US person controls a foreign corporation, the controlled-foreign-corporation regime can tax certain company profits in the owner’s hands before a cent is distributed. GILTI — the global intangible low-taxed income rules — was designed to pull the profit of exactly the kind of asset-light, IP-heavy company that founders build into the US net annually, regardless of whether you paid yourself. There are credits for foreign tax paid and elections that can soften the outcome, and the 1984 US-Cyprus treaty and the foreign tax credit exist to reduce double taxation. But “reduce double taxation” is not “no US tax”. The mechanics belong with a US adviser; the takeaway is that a Cyprus company is visible to, and reachable by, the US system.

The paperwork is not optional

Ownership of a Cyprus company usually brings US information filings with it. Form 5471 reports your interest in the foreign corporation; separate rules cover foreign financial accounts. These are information returns, but the penalties for getting them wrong or filing late are steep and largely automatic. A founder who sets up in Cyprus without lining up US filing help has not simplified their life — they have added obligations. Budget for a US preparer as part of the cost of the structure, not an afterthought.

What Cyprus still does for a US founder

None of this makes Cyprus pointless for an American — it makes the pitch narrower and more honest.

• A real EU operating base. A 15% corporate rate, EU market access and a credible place to employ people and hold IP. For a business that genuinely needs European substance and customers, that is the point, tax aside.
• Treaty and credit relief. The US-Cyprus treaty and the foreign tax credit are there to stop the same income being fully taxed twice. Used properly, Cyprus tax paid is generally creditable against US tax, so the structure is about managing the total, not stacking two full bills.
• Non-US people around you use it fully. Co-founders, spouses and staff who are not US persons can be Cyprus tax residents and non-dom in the ordinary way — 0% Special Defence Contribution on dividends, the whole benefit. The US limitation is personal to US persons, not to the company.

The wider Cyprus tax system is worth understanding on its merits, and the 2026 reform made the non-US case stronger — but read it knowing which parts apply to you.

Where the line actually sits

The cleanest way to think about it: Cyprus governs your Cyprus tax, and the US governs your US tax, and for a US person the second one does not go away. If your reasons for Cyprus are operational — EU presence, hiring, IP, non-US partners — the structure can be excellent. If your only reason is to stop paying US tax, Cyprus cannot deliver that, and any provider implying otherwise is setting you up for a Form 5471 problem. This is also why the “is Cyprus a low-tax haven” question needs a careful answer rather than a slogan — we take that apart in is Cyprus a tax haven.

What this means for you

If you are a US founder, plan the Cyprus side and the US side together from day one. Model the Cyprus company tax against your US position with advisers on both ends before you commit — a rough Cyprus estimate on the tax calculator is a starting point, not the whole picture. If you want the Cyprus structure built cleanly around your US reality rather than in denial of it, tell us how you are set up and read forming a Cyprus company from the USA first.
