What our customers say about us

Working with Sanders U.S. Tax Services has been excellent. Mr. Sanders is very competent and extremely reliable. I am really glad that I found this contact online and look forward to continuing our good working relationship!

I never look forward to the time of year I have to file my tax return (Dutch and US). Sanders helped me. Very knowledgable, very patient. I'll be back next year. Thanks!

Very pleased with the excellent service. No more EY for me.

I moved to Switzerland about 8 years ago and filing my U.S. tax returns has been a hassle ever since. I just realized I massively overpaid for the last years. I have now moved to Sanders US Tax and am very happy about it.

Frequently asked questions

Do I need to file a U.S. gift or estate tax return even if no tax is due?

Often, yes. Many situations don’t create an actual tax liability, but a filing can still be required—and this is especially common in international/cross-border cases.

When can a non-U.S. person be subject to U.S. estate tax?

Even if someone is not a U.S. citizen and not U.S. resident, U.S. estate tax may apply if they own U.S.-situated assets (for example U.S. real estate, certain tangible property located in the U.S., or securities of U.S. companies).

How is “residency” determined for U.S. estate tax purposes?

Estate tax uses a different concept than income tax. A person can be treated as resident for estate tax based on U.S. domicile (generally tied to physical presence and intent), even if they are not a resident for U.S. income tax purposes—or vice versa.
