If you are a U.S. citizen, have interests in the U.S., operate a foreign business entity, or are a U.S. citizen residing in Canada, it is crucial to be informed about the significant dates and deadlines related to income tax filing obligations.

At Wave Tax, we recognize the complexities involved in tax filing for our clients, and we have outlined the relevant U.S. tax filing deadlines that may pertain to you.

The primary deadline for submitting U.S. income tax returns to the Internal Revenue Service (IRS) is April 15. However, U.S. citizens or residents whose tax domicile and residence are substantially outside the United States and Puerto Rico are granted an automatic extension until June 15 (June 17 in 2024).

Additional Extensions

Additional extensions can be obtained by taking proactive measures, such as filing Form 4868, which provides an automatic extension to October 15.

Alternatively, you may submit a letter of explanation to the IRS; if accepted, this can extend the deadline by an additional two months to December 15 (December 16, 2024).

Moreover, filing Form 2350 allows for a special extension for U.S. expatriates to fulfill specific Foreign Earned Income Exclusion (FEIE) requirements, thereby extending the filing deadline to meet these criteria.

🛑 But careful, an extension to file your income tax return does not extend the deadline for tax payment. To avoid incurring penalties or late payment interest, it is essential to pay your taxes on time or simultaneously with the filing of an extension.

📌 Important: Dates are subject to annual adjustments and revisions. The deadlines listed below represent the applicable due dates for filing tax returns or forms in 2024 concerning the 2023 tax year.
