U.S. Tax Defense & Advisory for Cross-Border Individuals and Businesses

High-Stakes Compliance for Foreign Owners, Resident Aliens, and U.S. Expats.

Operating across borders doesn't just increase your tax complexity—it increases your risk. In an era where a single missed information return (like Form 5472) triggers automatic penalties starting at $25,000, you don't need a tax preparer; you need a U.S. tax architect.

O & G Tax and Accounting Services provides audit-defensible U.S. tax compliance and advisory services for individuals, families, investors, and businesses. Whether you are operating U.S. LLCs, navigating lawful permanent residence, or managing cross-border U.S. tax obligations, we help ensure the U.S. tax system works for you — not against you.
