When is State Income Tax Due?

State income tax deadlines can vary significantly depending on the state in which you reside. Generally, most states align their tax due dates with the federal tax deadline, which is typically on April 15th. However, some states may have different schedules or additional considerations.

Common Deadlines

  • Federal Tax Day: April 15th
  • State Extensions: Many states allow a filing extension, typically up to six months, resulting in a possible due date of October 15th.
  • Quarterly Payments: If you're self-employed or earn significant non-wage income, you may need to make quarterly estimated tax payments, usually due on April 15, June 15, September 15, and January 15 of the following year.

State-Specific Variations

States such as California and New York adhere to the standard April deadline, while others like Texas and Florida have no state income tax. Always check your state's Department of Revenue website for the most accurate information regarding due dates and any applicable penalties for late payment.

Conclusion

Being aware of your state's income tax due date is crucial for tax planning and avoiding penalties. To ensure compliance, mark your calendar, and consider consulting with a tax professional if you have questions or unusual circumstances regarding your tax filings.
