Delaware taxpayers should prepare for an important tax season, as the deadlines and procedures for the 2026 personal income tax returns are slightly different from the federal schedule. Tax season officially opened on January 26, 2026, with refunds expected to begin being issued on February 16. However, it’s essential for taxpayers to note that Delaware’s personal income tax returns are due later than the federal deadline, specifically on April 30, 2026.
Unlike many states that align their tax deadlines with the federal due date of April 15, Delaware allows residents and non-residents alike until the end of the month to file their individual income tax returns. It’s worth mentioning that if the due date falls on a weekend or a holiday, taxpayers will have until the next business day to file without facing penalties.
For those who require more time, Delaware offers an extension to file until October 15, 2026. It’s crucial for taxpayers to remember, however, that while extensions apply to filing, any taxes owed must be paid by the original April 30 deadline to avoid penalties and interest.
Taxpayers can conveniently file their returns online via the Delaware Taxpayer Portal at tax.delaware.gov, where they can also pay their taxes, check their refund status, and submit requests for extensions. Electronic filing is recommended as it typically speeds up the process and reduces the likelihood of errors that can lead to delays. For those who prefer traditional methods, paper forms and instructions are available through the Division of Revenue’s website.
The Division of Revenue has noted that while they generally begin issuing refunds on February 16, actual timing can vary significantly. Factors such as fraud prevention and identity verification processes may lead to delays, particularly for paper submissions or returns needing additional review. Taxpayers will have the option to track their refund status through the online portal once their return is filed.
For individual taxpayers who anticipate owing a substantial amount in state taxes, it may also be necessary to make quarterly estimated tax payments throughout the year. These payments are typically set for April 30, June 30, September 30, and January 31 of the following year.
As the tax season unfolds, Delawareans are encouraged to plan ahead to ensure timely filing and payment, thus minimizing stress and maximizing the likelihood of receiving refunds promptly. This proactive approach can provide peace of mind during this busy period.
