When Does Tax Season Start in 2026? Tax season is a critical time for millions of Americans, marking the period when individuals and businesses file their federal income tax returns for the previous year. For 2026, this means filing taxes for the 2025 tax year. If you’re wondering, “When does tax season start in 2026?” you’re not alone—this query spikes every year as people prepare to meet deadlines and maximize refunds. In this comprehensive guide, we’ll cover the expected start date, important deadlines, recent tax law changes, and essential tips to get ready. Drawing from official IRS resources and trusted financial experts, we’ll help you navigate the 2026 tax filing season smoothly.
What Is Tax Season and Why Does the Start Date Matter?
Tax season refers to the window when the Internal Revenue Service (IRS) accepts and processes federal income tax returns. It typically runs from late January through mid-April, with extensions available until October. Knowing when tax season begins in 2026 is crucial for early filers who want quick refunds, as the IRS processes returns on a first-come, first-served basis. Delaying could mean longer wait times, especially if you owe taxes or need to amend returns.
The start date also signals when tax software like TurboTax or TaxAct becomes fully operational for e-filing, and when employers must issue forms like W-2s and 1099s. Preparing early can help you avoid last-minute stress and potential penalties for late filing.
Expected Start Date for Tax Season 2026
As of late December 2025, the IRS has not yet officially announced the exact start date for the 2026 tax filing season. However, based on historical patterns and projections from reliable sources, the IRS is expected to begin accepting individual tax returns in late January 2026. In previous years, such as the 2025 tax season, filing opened on January 27.
Industry experts anticipate the 2026 season could kick off as early as January 26, 2026, which falls on a Monday—aligning with the IRS’s preference for weekday starts to ensure smooth operations. The official announcement is typically made in early January, so check the IRS website for updates. If you’re an early filer, mark your calendar for late January to submit your 2025 taxes promptly.
Key Tax Deadlines for 2026
While the start date sets the beginning, several milestones define the 2026 tax season. Here’s a breakdown of essential dates for individuals:
- January 15, 2026: Due date for the fourth quarter estimated tax payment for the 2025 tax year (if applicable).
- January 31, 2026: Employers must provide W-2 forms to employees, and payers must issue 1099 forms for non-employee compensation.
- April 15, 2026: Federal income tax return due date for most individuals (Form 1040 or 1040-SR). This is also the deadline to request a six-month extension using Form 4868, though any taxes owed must be paid by this date to avoid penalties.
- October 15, 2026: Extended filing deadline for those who requested an extension by April 15.
- Other Estimated Tax Payments: For the 2026 tax year, payments are due on April 15, June 16, September 15, and January 15, 2027 (adjusted for weekends/holidays).
Note that if April 15 falls on a weekend or holiday, the deadline shifts to the next business day. For fiscal-year taxpayers, deadlines align with their tax year end.
| Date | Deadline Description |
|---|---|
| January 15, 2026 | Q4 2025 estimated taxes due |
| Late January 2026 | Expected tax season start (IRS acceptance of returns) |
| January 31, 2026 | W-2 and 1099 forms issued |
| April 15, 2026 | 2025 tax returns due (or extension request) |
| October 15, 2026 | Extended filing deadline |
Tax Law Changes and Inflation Adjustments for 2026
The IRS has already released inflation adjustments for the 2026 tax year, which affect brackets, deductions, and exemptions. Key updates include:
- Standard Deduction: Increases to $32,200 for married couples filing jointly, $16,100 for singles, and $24,150 for heads of household.
- Tax Brackets: Adjusted upward by about 7% to account for inflation, potentially keeping more income in lower brackets.
- Exemption Amounts: For estate taxes, the exemption rises to $90,100 for unmarried individuals (phasing out at $500,000).
These changes aim to prevent “bracket creep” due to inflation. Consult IRS Publication 509 for a full tax calendar and detailed adjustments.
How to Prepare for the 2026 Tax Filing Season?
The IRS encourages taxpayers to “Get Ready” early to ensure accurate and timely filing. Here are actionable steps:
- Gather Documents: Collect W-2s, 1099s, mortgage interest statements (Form 1098), and records of deductions like charitable contributions or medical expenses.
- Create or Update Your IRS Online Account: Use IRS.gov to view past returns, make payments, and track refunds.
- Choose Filing Method: E-file for faster processing—over 90% of returns are filed electronically. Free File options are available for those with adjusted gross income under $79,000.
- Consider Professional Help: If your situation is complex (e.g., self-employment, investments), consult a tax advisor.
- Plan for Refunds or Payments: If expecting a refund, file early; direct deposit can deliver funds in as little as 21 days. If owing, set up a payment plan via IRS.gov.
By starting preparations now, you can avoid common pitfalls like missing documents or underpaying estimated taxes.
