IRS Filing 2026 Deadline: As per the reports, IRS tax filing 2025 income starts on January 26, 2026, because this date allows Americans to file their Form 1040 returns through electronic submission through website. If you want to check on the standard deadline, which remains April 15, 2026, for most people to submit returns and pay any taxes owed. Form 4868 can be used by taxpayers to obtain an extension that extends their filing deadline until October 15, 2026, but they need to make tax payments by April 15 to prevent penalties.

IRS Filing 2026 Deadline: Critical Deadlines

  • January 31, 2026: Employers are required to issue W-2s and also 1099 forms, which include 1099-NEC for nonemployee compensation.
  • April 15, 2026: This is the primary filing and payment deadline for individuals. This also includes quarterly estimated taxes (Q1 2026).
  • June 15, 2026: This is an automatic extension for U.S. expats abroad, but also includes taxes owed that are still due April 15.
  • October 15, 2026: Final extended filing deadline. As per the reports, no more extension dates will be given.

New for 2026, forms like 1099-DA report digital asset transactions, with electronic IRS filings due by March 31. Early filers who claim EITC or CTC can expect to receive their refunds between late February and early March.

IRS Filing 2026 Deadline: Who Must File?

Single filers under 65 must file if gross income exceeds the standard deduction, around $14,600 for 2025 (subject to updates). Collect essential documents before your appointment, which should include W-2s and 1099s, and all receipts that support your home office and charitable deduction claims.

IRS Filing 2026 Deadline: Extensions and Penalties

The first extension period lasts six months for taxpayers who file Form 4868, but they must estimate their tax liabilities because failure to do so results in 0.5 percent monthly penalties plus 5 percent interest on any unpaid amounts. Expatriates receive additional time to complete their work, but they must follow identical regulations.
