US tax season checklist 2027 for expats and digital nomads: key documents, deadlines, and steps

The 2027 US tax season can be particularly challenging for expats and digital nomads, with requirements like the FBAR, Foreign Earned Income Exclusion (FEIE), and specific deductions. This checklist helps you organize every step, from gathering documents to filing the correct forms before official deadlines. Use this list in Foco to track each task, set reminders, and avoid penalties for late submissions.

Why this checklist is essential for you

As an expat or digital nomad, you must report worldwide income but can also access tax benefits like the FEIE (up to $120,000 for 2026) or the Foreign Housing Exclusion. Additionally, if you have foreign bank accounts totaling over $10,000 at any point during the year, you must file the FBAR (FinCEN Form 114) by April 15, 2027, with an automatic extension available until October. This checklist covers all forms, deadlines, and actionable steps to ensure compliance.

In Foco, create a project called 'Taxes 2027' and use this list to break tasks into stages: document collection, calculations, filing, and follow-up. Assign due dates and reminders for critical deadlines like the FBAR or Form 1040 extension to stay on track.

• Gather all W-2, 1099 forms, and proof of income from US and foreign sources
• Collect bank statements for all non-US accounts to determine the maximum balance for the year (FBAR requirement)
• Obtain records of foreign housing expenses (rent, utilities) for the Foreign Housing Exclusion or deduction
• Verify eligibility for the FEIE (Physical Presence Test or Bona Fide Residence Test)
• Calculate total foreign earned income and compare it to the 2026 FEIE limit ($120,000)
• Download Form 1040 and Schedule 1 to report income and apply the FEIE (Form 2555 or 2555-EZ)
• Complete FinCEN Form 114 (FBAR) if the combined balance of foreign accounts exceeded $10,000 at any time during the year
• Check if you need to file Form 8938 (FATCA) for additional foreign assets (thresholds vary by filing status and residency)
• Request an automatic extension for Form 1040 (Form 4868) if you need more time to file (until October 15, 2027)
• Pay any estimated taxes owed by April 15, 2027, to avoid interest and penalties
• Review if your country of residence has a tax treaty with the US and whether it applies to your income (Form 8833)
• Consult a tax professional specializing in expat taxes if you have complex income (e.g., investments, business, or cryptocurrency)
• Submit the FBAR electronically via the BSA E-Filing system by April 15, 2027 (automatic extension to October)
• File Form 1040 and attached forms (2555, 8938, etc.) by April 15 or your extended deadline
• Save digital copies of all filed forms and supporting documents for at least 7 years
• Check your refund status on the IRS portal (Where’s My Refund?) if expecting a refund
• Update your mailing address with the IRS (Form 8822) if you moved during the year
