FAQs

Do I need to file Form 5471?

You might if you’re a U.S. person who owns at least 10% (by vote or value) of a foreign corporation, or you meet certain control or category change thresholds. A short discovery call confirms your category.

FBAR vs FATCA (8938) — which applies?

FBAR (FinCEN 114) covers foreign financial accounts when the aggregate balance exceeds $10,000 during the year. 8938 reports specified foreign financial assets based on higher FATCA thresholds. Many taxpayers file both.

How do I avoid double taxation?

With proper sourcing and the Foreign Tax Credit (Form 1116), you can often offset U.S. tax on foreign‑sourced income. Planning determines whether credits, exclusions, or treaty claims help most.

Can you work remotely with clients outside Massachusetts?

Yes. We support clients across the U.S. and abroad via secure portals, e‑signature, and video calls.
