Federal individual returns (Form 1040) for tax year 2025 are due April 15, 2026. C-corporation returns (1120) are also due April 15. S-corporation and partnership returns (1120-S, 1065) are due March 17, 2026. If you need more time, an extension gives you until October 15 — but any tax owed is still due in April.

Yes — we are fully bilingual in English and Mandarin. We also frequently translate foreign documents (bank statements, employment contracts, gift letters from family abroad) for inclusion in U.S. tax filings.

If your combined foreign account balances exceeded $10,000 at any point during the year, you must file an FBAR (FinCEN 114) by April 15 (auto-extended to October 15). Higher thresholds also trigger Form 8938 with your tax return. See our FBAR guide.

Pricing depends on complexity. A simple individual return typically starts around $350; business returns (1120-S, 1065) typically start around $900; monthly bookkeeping starts around $300/month. We provide a fixed-fee quote after the initial consultation — no surprises.
