Online Taxman
(this site) is where it started. US expat tax preparation and compliance for Americans abroad, including back taxes, foreign asset reporting, non-resident returns, and planning for people earning in more than one country.
Vincenzo Villamena is a CPA and the founder of Online Taxman, Global Expat Advisors, and Entity Inc. He is a Forbes Business Council contributor, co-author of a book on US taxes for Americans abroad, and a frequent podcast guest.

Vincenzo Villamena, CPA, has spent more than two decades in tax, accounting, and cross-border finance. His background includes a tenure at a Big Four accounting firm in New York City and years in private equity, working across audit, tax, valuation, and deal structuring. He founded Online Taxman after leaving that career and moving abroad himself. The firm exists because he needed what it now provides: US citizens keep filing US returns no matter where they live, and very little about that process is built for them.
Over 15+ years, Online Taxman has grown into a globally distributed team of CPAs, enrolled agents, and international tax specialists who have filed more than 25,000 returns for clients in 182 countries. Vincenzo holds a Master of Accounting and a Bachelor of Business Administration with distinction from the University of Michigan's Stephen M. Ross School of Business, and he is a licensed Certified Public Accountant.
Vincenzo built each of his three firms around a different stage of an international life. Together they cover living abroad, structuring across borders, and entering the US market.

serves founders coming the other direction. Non-US residents forming and running a US company, with incorporation, federal and state compliance, and bookkeeping.
If your situation calls for one of the others, we will say so. Clients often start with an expat return here and move into structuring work with Global Expat Advisors years later, and non-US founders who come to us to open a US company are usually better served by Entity Inc.
Behind all three is a shared bench of international tax specialists and Vincenzo's view that compliance should not be the reason someone gives up on the life they want.
Vincenzo hosts the Online Taxman YouTube channel, where he works through the questions clients actually bring him: how the Foreign Earned Income Exclusion interacts with the Foreign Tax Credit, what the streamlined procedure really involves, and which pieces of expat tax advice circulating online are wrong.
Written with John Hamilton, CPA, his co-founder at Online Taxman, the book covers the rules that affect Americans abroad most often: the Foreign Earned Income Exclusion, the Foreign Tax Credit, foreign asset reporting, and what happens when filings have been missed.

Start with Online Taxman if you need US returns prepared, back filings brought current, or foreign asset reporting handled. Global Expat Advisors is the better fit when the question is how to structure assets, entities, or an estate across several countries rather than how to file for one year.
If you are a US citizen or green card holder, Online Taxman. If you are a non-US resident who wants to form and run a US company, Entity Inc. is built for that.
