Understanding the 2026 Tax Filing Season: Key Forms and Considerations

As taxpayers prepare for the 2026 tax filing season, many anticipate larger refunds, prompting some to file their returns sooner. However, experts caution against rushing the process, emphasizing the importance of having all necessary tax forms to avoid potential delays and complications.

Taxpayers must be aware of various information returns that employers and financial institutions provide, including Forms W-2 and 1099. These forms report income and other financial transactions to both the taxpayer and the IRS, facilitating the agency's ability to identify discrepancies. April Walker, a senior manager for tax practice and ethics at the American Institute of CPAs, highlights that "one of the best ways to avoid [an IRS audit] is to make sure that you are fully and completely reporting everything." Errors or omissions can lead to an automated CP 2000 notice from the IRS, which outlines missing information and proposed adjustments.

The 2026 filing season may present unique challenges due to a 27% reduction in the IRS workforce and leadership turnover, as noted in a report by the National Taxpayer Advocate. These factors could result in delays in taxpayer services, making it crucial for individuals to file their returns accurately the first time. Taxpayers can expect to receive various forms throughout the filing season, with many arriving in late January, while others, such as 1099s for investments, may not be available until mid-February or later.

This tax season, some filers will encounter Form 1099-DA for the first time, which reports digital asset transactions from the previous year. Additionally, taxpayers claiming new deductions for tip or overtime income may need to calculate their qualified income independently, as employers may not report these figures on W-2s or 1099s. Other forms, such as 1098-E for student loan interest and 5498 for individual retirement account contributions, will assist filers in claiming tax credits and deductions.

Critics express concerns regarding the IRS's ability to manage the increased workload amid staffing reductions. The National Taxpayer Advocate's report indicates that these challenges could hinder the agency's efficiency in processing returns and addressing taxpayer inquiries, potentially leading to frustration among filers.

Experts recommend that taxpayers remain vigilant in ensuring their returns are complete and accurate. The AICPA advises that while many forms are expected early in the season, some may require additional time, underscoring the importance of patience and thoroughness in the filing process.
