A personal blog by Vasily Vitalyev on cross-border tax, personal finance, and the practical side of building a life across borders.

Important: Nothing on this blog is financial, tax, legal, or investment advice. I write from personal experience and public sources. You are responsible for your own decisions and for verifying anything that affects your taxes, your money, or your residency. When stakes are high, talk to a licensed professional in your country.

What this blog is about

If your life crosses borders — through work, family, business, or just curiosity — most of the standard tax and personal finance content online won’t help you. Generic articles assume one country, one tax system, one set of rules. Real cross-border situations are messier than that.

This blog covers the topics I work through in my own life and with people I help: residency rules, tax treaties, foreign earned income, expat banking, FATCA and CRS, retirement accounts in multiple jurisdictions, real estate abroad, and the operational side of moving between countries.

About me

I love cars

I’m Vasily Vitalyev. I’m CTO at CelluNous, a mobile company, and I’m a business advisor for Taixable, a cross-border tax planning platform. I’m not a licensed tax advisor, lawyer, or financial planner. I write here as a practitioner and an interested observer of how cross-border tax actually works in practice.

If you want to know more about me, my background, and how this site is run, see the About page.

Topics I cover

International tax — residency, treaties, foreign income, FEIE, FTC, treaty tie-breakers
Personal finance abroad — multi-currency banking, retirement accounts across countries, investing as a non-resident
Country guides — focused looks at specific destinations: Spain, Portugal, UAE, and more
Expat living — healthcare, schools, family logistics, the day-to-day operational reality
Cross-border banking — opening accounts in multiple countries, FATCA / CRS reporting, fintech vs. traditional
Digital nomad — when the lifestyle works, when it doesn’t, and the tax traps along the way

Other writers on this blog

This is primarily my blog, but two collaborators contribute occasional posts on topics close to their own experience:

Sarah Chen writes about offshore real estate and personal finance for non-residents.
Marcus Holloway writes about practical mobility — banking, healthcare, and the operational side of moving abroad.

About Taixable

I sometimes mention Taixable in posts where the platform is genuinely the right tool for the situation — usually when someone needs to model out a multi-country tax outcome before making a decision. I’m a business advisor for the company, so disclose that openly. I don’t get paid per click or per signup; if I link to it, it’s because I think it’s useful for the situation in the post. When other tools are better for the job (Wise, IRS publications, HMRC guidance, country-specific resources), I link to those instead.
