Mark Anderson, US CPA in Thailand & US Expat Tax Help

  Every year, thousands of Americans living abroad open their laptop, fire up a tax software platform, and assume that if the software accepts their inputs, they must be doing it right. That assumption is costing them thousands of dollars in missed exclusions, triggering IRS audits, and generating FBAR penalties that dwarf the cost of professional help. The choice between an expat CPA consultation and DIY tax software is not simply a matter of convenience or price — it is one of the most financially consequential decisions an American abroad makes each filing season. This guide breaks down exactly where DIY software fails, what professional US expat tax services cover that software cannot, and how to know which path is right for your specific situation in 2026. Why DIY Tax Software Was Not Built for Expats The major tax software platforms — TurboTax, H&R Block, FreeTaxUSA — were engineered for domestic filers. While several have added international features over time, the exp...

  Running a business from abroad as an American comes with freedom, opportunity, and a tax compliance burden that most domestic entrepreneurs never face. The IRS taxes US citizens on worldwide income regardless of where they live or where their business operates — and in 2026, the agency is deploying advanced AI and data-matching systems that flag inconsistencies with greater precision than ever before. For expat business owners, clean and accurate US bookkeeping is no longer a back-office nicety. It is one of the most powerful audit-prevention tools available, and the foundation on which all quality US expat tax services are built. This guide explains exactly which IRS audit triggers expat business owners face, how poor recordkeeping creates those risks, and what professional US bookkeeping delivers that protects your business year-round. Why Expat Business Owners Face Elevated Audit Risk The IRS uses a system called the Discriminant Information Function (DIF) to score every ta...

  Filing season arrives every year, and for Americans living abroad, it brings a degree of complexity that no domestic tax software was ever designed to handle. The United States taxes its citizens on worldwide income regardless of where they live — and the rules governing exclusions, credits, foreign account reporting, and state obligations change annually. Before you file a single form, scheduling an expat CPA consultation is not simply good practice. In 2026, it is the single most important step you can take to protect your finances. This guide explains exactly what a US expat tax advisor does before filing season, what critical decisions get made in that consultation, and why the cost of skipping it can far exceed the cost of the consultation itself. What the US Tax System Actually Requires of Americans Abroad Many expats still believe that paying taxes in their host country satisfies their US obligations. It does not. The IRS requires US citizens and green card holders to fi...

  For Americans living abroad, the FBAR is one of the most important — and most misunderstood — annual reporting requirements under US law. Many expats only discover they needed to file after receiving a frightening IRS notice. Whether you are new to foreign account reporting or years behind on compliance, understanding how FBAR filing services work in 2026 can protect you from penalties that can be financially devastating. This guide explains exactly what the FBAR is, who must file, the 2026 deadlines, what happens if you miss them, and how professional FBAR reporting services help you stay fully compliant. What Is the FBAR? FBAR stands for Foreign Bank Account Report, officially filed as FinCEN Form 114. It is not a tax form — it is a financial disclosure report submitted to the Financial Crimes Enforcement Network (FinCEN), a bureau of the US Treasury Department. The FBAR is filed separately from your federal tax return and has its own deadlines and penalty structure. Per the ...
