Federal Tax Deadlines for Individuals in 2026

For most taxpayers, the federal tax year runs from January 1 to December 31. Here are the key dates you need to remember:

• April 15, 2026: Deadline to file your 2025 individual income tax return (Form 1040) or request an extension. If you owe taxes, payment is due by this date to avoid penalties.

• October 15, 2026: Final deadline to file your 2025 tax return if you requested an extension by April 15.

• June 15, 2026: Deadline for U.S. citizens or residents living abroad to file their tax returns or request extensions.

• January 15, 2026: Fourth quarter estimated tax payment due for 2025 if you pay quarterly.

  
  

Missing these deadlines can result in late fees and interest. Barrett Accounting and Tax Services can help you prepare and file on time, ensuring you avoid costly mistakes.

Important Dates for Small Businesses and Self-Employed in Georgia

Small business owners and self-employed individuals face additional deadlines. Here’s what you need to track:

• March 15, 2026: Deadline for S corporations and partnerships to file their 2025 tax returns (Forms 1120S and 1065) or request extensions.

• April 15, 2026: Deadline for sole proprietors and single-member LLCs to file individual returns including Schedule C.

Georgia also requires businesses to file state income tax returns and pay sales tax on time. The state deadlines generally align with federal dates but confirm with the Georgia Department of Revenue for any updates.

Georgia State Tax Deadlines to Remember

Georgia residents and businesses must meet state tax deadlines in addition to federal ones. Key dates include:
