Uruguay’s 12% Tax Goes Deeper: The Look-Through Rule and the US-Expat Trap

Uruguay’s new tax on foreign income is broader than the headline 12% suggests. A fiscal-transparency rule now looks through offshore companies to tax the resident behind them.

For US expats, the exposure is real. They have no tax treaty to fall back on, so the risk of being taxed twice is genuine.

More than a 12% rate

Since 2026, Uruguay has taxed most foreign-source capital income of its tax residents at a flat 12%. That covers interest, dividends, foreign rents and certain capital gains.

The headline rate has been widely reported. Much of the coverage stopped there, and that left an important part of the rule out of view.

A fiscal-transparency rule comes with the tax, and it is less understood. It attributes income earned through a non-resident entity directly to a Uruguayan resident who is its beneficial owner.

In plain terms, the rule follows the money back to the person. The type of company or structure in the middle does not change the outcome.

How the look-through works

Say a resident holds more than 5% of a foreign company. The income that company earns can then be attributed to them personally, whatever structure they used.

In effect, the offshore company is looked through. What sits behind it is a resident taxpayer, and that is who the rule reaches.

This closes an assumption many new residents made. They believed that holding assets inside a foreign entity kept the income outside Uruguay’s reach.

Under the transparency rule, that belief no longer holds. Ownership above the 5% threshold is what matters, not the wrapper around the assets.

Why US expats are most exposed

American taxpayers face the sharpest exposure of any group. The United States taxes its citizens on worldwide income, wherever they happen to live.

There is no US-Uruguay tax treaty to soften that overlap. So the same dividends or gains can be taxed by both countries at once.

The tool that prevents genuine double taxation is the foreign tax credit. It offsets tax paid in one country against the tax owed in the other.

Claiming it correctly is the priority for anyone caught by both systems. That means using the right US forms and keeping the numbers consistent across borders.

The tightened residency incentives

Uruguay still offers new residents a choice of regimes. These include a long holiday on foreign income and a reduced flat rate.

The routes into the most generous holiday have been narrowed for new arrivals. What once was an easy entry now asks for more.

The low-presence path many people used has given way to other options. These are built around a substantial property or productive investment.

Anyone weighing a move should confirm the current thresholds first. Rules like these can shift, so it pays to check before committing.

What to do

Are you a Uruguayan tax resident with offshore holdings? Start by mapping who owns what and whether the 5% threshold is crossed.

The transparency rule can pull income onto your personal return that you did not expect. A clear ownership picture is the first step to avoiding surprises.

US taxpayers should coordinate a Uruguayan accountant with a US cross-border adviser. That way the credit is claimed cleanly on both sides.

None of this is advice, and the mechanics reward getting help early. A little planning now can prevent a costly tangle later.
