Taxes for Expats vs Expatfile: Full-Service vs DIY Expat Tax Filing

TFX and Expatfile solve different problems: TFX is professional preparation, while Expatfile's lower-priced core plans are self-service software.

What this issue means for Americans abroad

TFX currently publishes a federal expat return starting at $450, with additional international forms charged where relevant.

Expatfile currently lists Standard at $119, Premier at $159 and Investor at $199 per return. It also advertises a $499 Unlimited full-service option, which is a more direct comparison with a professional-preparation firm than its DIY plans.

The main decision is therefore not simply $450 versus $119. It is whether you want to prepare through software or hand preparation to a professional workflow.

A practical way to work through it

Start with the filing obligation before deciding which exclusion, credit, treaty position, information return, or reporting exception might apply. U.S. citizens and resident aliens abroad are generally taxed on worldwide income, but the mechanism for reducing double taxation and the forms required depend on the income, asset, account, entity, and country involved.

1. List every international form you expect to need, not just Form 1040.
2. Decide whether you want DIY software, professional review, or full preparation.
3. Compare the all-in price for FBAR, FATCA, business, investment, and catch-up work.
4. Check who is responsible for final return review and filing.

Common mistakes to avoid

• Comparing unlike service tiers as if they were equivalent.
• Choosing a DIY plan when your required form is unsupported.
• Assuming a professional-service headline price includes every international information form.

Do not assume that paying tax in another country, being below a local filing threshold, or using a foreign account automatically removes a U.S. filing or information-reporting requirement. Conversely, do not assume every foreign asset requires every international form. The definitions and thresholds differ by regime.

Records worth gathering before you file

Keep the documents that establish ownership, dates, balances, income, taxes paid, exchange-rate conversions, and your residence/work pattern. For accounts and assets, year-end values may not be enough because some U.S. reporting tests use the highest value during the year. For treaty or totalization positions, keep the official certificates or statements supporting the position.

When professional preparation may be useful

Specialist help becomes more valuable when several international systems overlap—for example, a foreign company plus salary, a pension plus investment accounts, several missed years, a move between countries, or a filing position that depends on a treaty. The useful comparison is the complete form set and review scope, not just the cheapest advertised base return.
