Staying ahead of the 2026 deadlines is essential for businesses preparing ACA, 1099, and W-2 filings. This guide highlights the key dates you need to know to stay compliant and avoid costly penalties while helping you plan, prepare, and file with confidence.
Basic Information
At the end of each year, employers must be sure they complete all filing requirements during the filing season. This includes submitting forms to the IRS and applicable states, distributing recipient copies, making corrections when needed, and ensuring everything is finished by the due dates.
Because the IRS now requires most businesses filing 10 or more forms to submit them electronically, it’s important to prepare early and verify you meet the correct filing method. Most businesses fall under this requirement. Failing to file on time, submitting in the wrong format, or submitting incorrect information can result in penalties.
As 2025 wraps up, employers will need to prepare their IRS submissions and meet all 2026 deadlines for Form 1099, Form W-2, and ACA filings.
2026 Deadlines
It’s best to begin working on your filings early so you have ample time to gather info, complete forms, and review everything for accuracy. Starting ahead of schedule helps reduce last minute errors and delays.
The chart below outlines the key 2026 deadlines for tax year 2025 forms so employers can plan ahead with confidence.

State Filing
These are only a handful of the federal IRS form deadlines. In addition to these, many states have their own deadlines and their requirements can vary significantly. Always confirm your state’s specific filing rules, due dates, and submission methods, since they may differ from federal timelines.
Many states participate in the Combined Federal/State Filing program for certain Forms 1099 including 1099-B, DIV, G, INT, K, MISC, NEC, OID, PATR, and R. States that do not participate may require a separate direct filing. You can check whether your state participates by reviewing our CF/SF list.
