My LLC had no profits. Do I still need to file the 1040-NR?

It depends on whether there was income connected to the US and on your situation. The LLC itself may still owe Form 5472 even with zero revenue. We confirm it in the initial consultation.

What happens if I don't file?

The IRS applies penalties and interest on unpaid tax, and you lose the right to claim deductions, treaty benefits and withholding refunds.

30% was withheld from my dividends. Can I get some of it back?

If your country has a tax treaty with the US, or the withholding exceeded your actual tax, the 1040-NR is the mechanism to claim the refund.

Can I file the 1040-NR myself?

You can. But the form changes with your income type, treaty and structure. A typical mistake costs more than the accountant's fee. Our service exists so it is filed correctly and on time.

Do you work in Spanish?

Always. The entire process, consultation, preparation and filing, is with accountants who speak your language.

Form 1040-NR: preparation & filing

Form 1040-NR, the US Nonresident Alien Income Tax Return, is filed by people who are not US tax residents but earn income there: LLC profits, wages, professional fees, rental income or dividends. You do not need to live in the US to have a filing obligation. Having income connected to the country is enough.

We review your case, determine whether you must file, and handle the entire process, with an accountant who explains every step in your language. Our team has prepared returns for founders across Latin America and Spain for more than two decades.

Who files a Form 1040-NR.

The 1040-NR applies whenever a non-resident has income connected to the United States. The most common cases:

Foreign owners of an LLC: if your single-member LLC earns income connected to the US, the profit is reported on your personal 1040-NR. Progressive rates run from 10% to 37%.
Foreign partners in a multi-member LLC: the partnership reports each partner's share, and you settle your portion with the 1040-NR.
Non-residents with US-source wages or professional fees: income for work connected to the United States is reported here.
Owners of US real estate with rental income: rent from US property is US-source income, and belongs on the 1040-NR.
Anyone recovering excess withholding: if more was withheld than you owed, the 1040-NR is how you claim the refund.

The 1040-NR and Form 5472.

If you are the sole foreign owner of an LLC, your company files Form 5472 (with a pro-forma 1120) every year to report transactions with you, and you file the 1040-NR when there is income connected to the US. They are separate obligations, with separate penalties: failing to file the 5472 starts at $25,000; a missed 1040-NR generates penalties and interest on the tax owed, and forfeits your right to refunds or treaty benefits.

You do not need to live in the United States to have a US return. Having income connected to the country is enough.

We coordinate both, so your tax year is complete and nothing is left open.
