Best Tax Filing Services for US Expats in 2026

Filing US taxes from abroad is not optional. Every US citizen and green card holder must file an annual federal tax return, no matter where they live. But most mainstream tax software was built for domestic filers and struggles with the forms expats need: Form 2555 (Foreign Earned Income Exclusion), Form 1116 (Foreign Tax Credit), Form 8938 (FATCA), and FinCEN 114 (FBAR).

This guide compares the best options available in 2026 -- from DIY software to full-service CPA firms -- so you can pick the right tool for your situation and budget.

DIY Software: File It Yourself

MyExpatTaxes -- Best All-in-One Expat Software

MyExpatTaxes was created in 2018 by Americans living abroad and is designed specifically for expat tax situations. It covers all the forms expats typically need -- FBAR, FATCA (Form 8938), FEIE (Form 2555), FTC (Form 1116), and treaty claims (Form 8833) -- all included in the base price. No upsells for individual forms.

Pricing: $189 for federal filing. Free human support included at every tier. Awarded "Best Expat Tax Software" by The Balance. 4.8/5 on Trustpilot (2,000+ reviews).

Limitations: No state tax filing. More expensive than Expatfile for simple returns. No support for complex business structures (need CPA for that).

Best for: Expats who want one tool that handles everything including FBAR, FATCA, and treaty claims.

Expatfile -- Most Affordable Specialized Option

Expatfile focuses on simplicity and speed. Many users report completing their return in under 15 minutes. It handles the core expat forms (FEIE, FTC) well and has a clean, modern interface.

Pricing: $119 (Standard), $159 (Premier with Child Tax Credit), $499 (Unlimited with CPA review). FBAR is an extra $59. 5 stars on Trustpilot (7,000+ reviews).

Limitations: No FATCA (Form 8938), no treaty claims (Form 8833), no state returns. FBAR costs extra. Not suitable for complex situations (PFICs, rental income abroad).

Best for: Straightforward expat returns (salary + FEIE/FTC) on a budget.

H&R Block Expat -- Hybrid DIY + Professional

H&R Block offers both DIY software and full-service preparation for expats. The DIY tier includes Form 2555 and Form 1116. The professional tier connects you with a tax advisor who handles everything.

Pricing: DIY from $109. FBAR is an extra $49. Full-service starts at $349. Advantage: state tax filing is supported.

Limitations: Missing Form 8938 (FATCA) and Form 8833 (treaty). The DIY interface is not as expat-focused as MyExpatTaxes or Expatfile.

Best for: Expats who want a recognized brand with the option to escalate to a professional.

TurboTax and TaxAct -- General Software

TurboTax and TaxAct can generate Form 2555 and Form 1116, and TurboTax can produce Form 8938 for FATCA. However, neither can file FBAR -- you must do that separately through the BSA E-Filing system. Neither supports Form 8833 for tax treaty claims.

Pricing: TurboTax starts at $69 (but expat forms require the Premier tier at $129+). TaxAct starts at $49.

Best for: Simple cases with no foreign bank accounts over $10K and no treaty claims needed.

Full-Service CPA Firms: Let a Professional Handle It

If your tax situation involves PFICs, foreign rental income, self-employment across borders, catch-up filing (Streamlined Procedure), or you simply want peace of mind, a CPA firm specializing in expat taxes is the way to go.

TFX is the most established firm in the space with 25+ years of experience. 100% success rate with the Streamlined Filing Compliance Procedure for delinquent filers.

How to Choose: Decision Framework

Key Forms Every Expat Should Know

• Form 1040 -- your standard US federal tax return (required for all).
• Form 2555 -- Foreign Earned Income Exclusion (FEIE). Excludes up to ~$126,500 of foreign-earned income (2026).
• Form 1116 -- Foreign Tax Credit (FTC). Credits taxes paid to a foreign country against your US tax bill.
• FinCEN 114 (FBAR) -- Report of Foreign Bank Accounts. Required if aggregate foreign accounts exceed $10,000 at any point. See our FBAR Filing Guide.
• Form 8938 (FATCA) -- Statement of Specified Foreign Financial Assets. Higher thresholds than FBAR. See our FATCA guide.
• Form 8833 -- Treaty-Based Return Position Disclosure. Needed to claim tax treaty benefits.

Free Options

The IRS Free File program is available if your adjusted gross income (AGI) is under $84,000. Partner software (including some TurboTax and TaxAct versions) is free for federal filing. However, these free versions typically don't support the expat-specific forms. You'll still need to file FBAR separately and may need to upgrade for Form 2555.

Key Deadlines for 2026

• April 15, 2026 -- Standard federal tax return deadline (automatic 2-month extension to June 15 for expats).
• April 15, 2026 -- FBAR deadline (automatic extension to October 15).
• June 15, 2026 -- Extended deadline for US citizens and residents living abroad.
• October 15, 2026 -- Final extended deadline (must request extension by April 15).

Bottom Line

For most US expats, MyExpatTaxes offers the best balance of coverage and ease of use -- it handles FBAR, FATCA, FEIE, FTC, and treaty claims in one platform. Expatfile is a great budget option for simple returns. If your situation is complex (PFICs, foreign rental, catch-up filing), invest in a specialized CPA firm like Greenback or TFX.

Whatever you choose, do not ignore your filing obligation. The penalties for non-compliance (especially FBAR) are severe, and the IRS has increasingly effective tools to find unreported foreign accounts.
