WHO WE WORK WITH

If any of these sound familiar,
we should talk.

You're a US citizen living abroad earning $100K+ and you've been told FEIE is the answer — but no one has walked you through whether FEIE or Foreign Tax Credit actually saves you more in your specific country.

You haven't filed US taxes in two, three, or five years and you don't know how deep the hole is or how to come back without massive penalties.

You're a digital nomad with income in multiple currencies, multiple countries, and a US passport — and your current CPA in the US has no idea what to do with you.

You're an international founder who needs a US LLC or C-Corp to access US payment processors, US clients, or US investors — and you don't know which entity, which state, or how it interacts with your home-country tax.

You're paying double tax somewhere you shouldn't be, or single tax somewhere you should be paying, and you can't get a straight answer from anyone.

WHAT EXPATS SAY

From the expats and founders
who finally got it sorted.

Sarah — US expat founder in Lisbon, Portugal
Sarah, US Citizen · Founder · Lisbon, Portugal
5 years back taxes filed. Zero penalties.

I'd been living in Portugal for five years and hadn't filed US taxes once. I was terrified. Vincenzo's team walked me through Streamlined Filing, got me fully compliant, and I didn't pay a single dollar in penalties. They genuinely understood the expat situation in a way my old US accountant never did.

Marcus — UK founder in London
Marcus, International Founder · UK Citizen · London
US LLC set up. Stripe live in 14 days.

I'm a UK founder trying to access US payment processors and US clients. Online Taxman set up my US LLC, handled the EIN, got my Stripe account approved, and structured the whole thing so I'm not double-taxed. Fourteen days from first call to live US business.

Priya — US digital nomad in Bali
Priya, Digital Nomad · US Citizen · Bali
FEIE to FTC switch. Saved $11K year one.

I'd been claiming FEIE for three years because my previous CPA told me to. Vincenzo modelled both FEIE and Foreign Tax Credit for my actual situation in Indonesia and showed me FTC saved me $11,000 in year one. He's the first accountant who actually did the math instead of defaulting.

ABOUT VINCENZO

Hi, I'm Vincenzo.
I built this firm for people like you.

Vincenzo Villamena, CPA — Founder, Online Taxman

I'm a US-licensed CPA. I started my career at PricewaterhouseCoopers in New York handling Fortune 100 audits and M&A. I later partnered at 4 Corners advising high-net-worth clients on private equity and business structuring. I have a Bachelor of Business Administration and a Master of Accounting with distinction from the University of Michigan's Ross School of Business.

I founded Online Taxman after I transitioned to working remotely from South America myself — and realised almost every American expat I met was getting the same incomplete advice from CPAs back in the US who'd never lived abroad and didn't understand how FEIE, FTC, foreign entity structuring, and US compliance actually fit together.

I co-authored US Taxes For Americans Abroad. I contribute to the Forbes Business Council. And I built this firm so American expats, digital nomads, and international founders could finally get US tax handled properly — by people who actually understand the situation, entirely remotely, from wherever you live.

QUESTIONS BEFORE YOU BOOK

Common questions before the call.

Yes. The first 20-minute call is at no cost. We use it to understand your residency, income structure, and current tax position. If we're not the right fit, we'll tell you on the call.

Probably less trouble than you think. The IRS offers a programme called Streamlined Filing Compliance Procedures specifically for expats who fell behind without intent to evade. Most clients catch up with zero or minimal penalties. We handle the full submission.

Yes. Through our sister venture Entity Inc., we set up US LLCs and C-Corps for international founders who need to access US payment processors, US clients, or US investors. We handle entity formation, EIN, registered agent, banking introductions, and ongoing US compliance.

It depends entirely on which country you live in, your income level, and your tax situation in your country of residence. The honest answer is: we model both for your specific situation. Default advice without modelling usually leaves money on the table.

Online Taxman is remote-first. We work with American expats, digital nomads, and international founders in 80+ countries. Everything happens online. Our team is based across multiple time zones to cover global client needs.

You'll receive a calendar confirmation and a short pre-call questionnaire about your residency, income, and current filing status. On the call, Vincenzo or a senior team member reviews your situation, identifies the right service path, and outlines pricing. If we move forward, you'll receive a written engagement letter with flat-fee pricing.

One firm. One call. One decision.

If you're an American expat, a digital nomad, or an international founder and you're ready to get US tax handled properly — book the free 20-minute call.
