The deadline for filing tax returns depends on the country and type of filer:

• In the United States for the 2024 tax year (filed in 2025), individual tax returns are due by April 15, 2025. If more time is needed, taxpayers can file Form 4868 to request an extension until October 15, 2025. Further extensions may be granted until December 15, 2025, for special circumstances. Taxes owed should still be paid by April 15 to avoid interest.

• In Australia, individual tax returns must be lodged by October 31 each year if self-lodged. Tax agents may have later lodgment schedules if engaged before October 31.

• In the United Kingdom, self-assessment tax returns for the tax year ending April 5, 2025, must be submitted by October 31, 2025, for paper returns and January 31, 2026, for online returns. Tax payments are also due by January 31, 2026.

These deadlines cover the most common scenarios for individuals in these countries. Other deadlines apply for businesses, expats, and special circumstances.
