The 2026 tax filing season now open marks an important financial milestone for millions of Americans, including households and business owners across Seattle. Whether you expect a refund or anticipate owing taxes, understanding deadlines, filing options, and preparation steps can save you time, stress, and potentially money.
This guide breaks down exactly what Seattle residents need to know right now, with practical insights to help you file accurately and avoid costly mistakes.
When Did the 2026 Tax Filing Season Open?
The Internal Revenue Service officially opened the 2026 tax filing season on January 26, 2026, and began accepting federal individual income tax returns for tax year 2025.
Taxpayers are required to file their returns and pay any taxes owed by April 15, 2026.
The IRS expects roughly 164 million individual tax returns to be submitted this year, with most filed electronically.
What this means for Seattle residents: Filing early can reduce identity theft risk, speed up refunds, and give you time to correct errors if needed.
Why This Filing Season Matters More Than Usual
Several tax law provisions enacted in 2025 are now taking effect and could impact credits, deductions, and total tax liability.
While additional IRS guidance may follow, many taxpayers could see changes in their refund expectations due to these updates.
Practical takeaway: Do not assume your refund will mirror last year’s results. Even small regulatory changes can alter your tax outcome.

How Fast Will You Get Your Refund?
