Serving Founders in 50+ Countries: The Biggest U.S. Tax Mistakes We Help Fix

At Bookmate, we’ve built our service with one group in mind: global founders running U.S. businesses. While we’re headquartered in the U.S., our clients span more than 50 countries—and counting.

If you’re managing a U.S. LLC, C Corporation, or earning U.S.-source income as a nonresident, we’re here to help you stay IRS-compliant, no matter where in the world you’re based.

Why Your Country Matters in U.S. Tax Filing

The country you live in affects:

  • Which forms you need to file (like 5472, 1120, or 1040-NR)
  • Whether you need to file as an individual, business, or both
  • How payments to you or your company are treated by the IRS
  • Whether U.S. tax treaties apply to your income

That’s why we tailor our guidance based on your residency, entity structure, and business activity in the U.S.

Where Our Clients Are

Here are just a few of the countries we frequently support:

Canada: Founders from Canada often open U.S. LLCs or C Corps to serve American clients or access U.S. investors. We help them file Forms 1120, 5472, or 1040-NR, and clarify when treaty benefits may apply.

Europe (including the UK): Whether it’s the United Kingdom, Germany, France, the Netherlands, or Spain, we support European founders launching U.S. companies for e-commerce, SaaS, or remote consulting. We handle multi-member LLC filings (1065), single-member LLCs with 5472, and personal nonresident returns when needed.

Latin America: Entrepreneurs from Brazil, Mexico, Argentina, Colombia and beyond use U.S. entities for Stripe access, payment gateways, and client acquisition. We help structure these setups properly and file all IRS-required forms—often 1120 + 5472 or 1040-NR.

Asia & the Pacific: From India to Singapore to the Philippines, we support founders building U.S.-based tech startups, digital agencies, or online stores. Many operate via Delaware C Corps or Wyoming LLCs. We manage their IRS filings, including pro forma 1120s and cross-border compliance.

Middle East & Africa: We serve growing numbers of founders in the UAE, South Africa, Nigeria, and more. Many start U.S. companies for global credibility or to work with U.S. partners. We guide them on proper structure and handle 5472/1120 or 1040-NR filings as needed.

Australia & New Zealand: Startups from this region often target the U.S. market early. We help them form and manage their compliance as they grow, ensuring their U.S. taxes are handled properly from day one.
