As we step into 2024, it’s crucial to start planning for the upcoming tax season. Whether you’re an individual taxpayer or a business owner, being aware of your state’s tax filing deadlines well in advance can help you avoid potential penalties or fines. This article will guide you through key points and dates related to state tax filing deadlines in 2024.

Why are state tax filing deadlines important?

State tax filing deadlines determine the due date by which all taxpayers must submit their income taxes along with any other relevant documentation. Each state sets its own deadlines, which may differ depending on the type of taxpayer (individual vs. business), the type of income earned, and the total amount of taxable income.

Failing to meet the deadline can result in various penalties, including late fees, interest charges on unpaid taxes, and even legal action against non-compliant taxpayers.

Important Dates for State Tax Filing Deadlines

Here are some important dates that you should mark on your calendar:

  • January 29th, 2024: Official start date for the tax season.
  • April 15th, 2024: Federal Income Tax Return Deadline (unless an extension is granted).

Several states align their deadlines with the federal government, while others have their own schedules. For instance, states like Colorado, Kentucky, and Massachusetts align their deadlines with the federal government, while states like New Jersey and Oregon prioritize earlier filings.

Note that some states may offer extensions beyond these initial standardized deadlines based on certain circumstances. However, it does require submitting formal applications before the relevant authority within adequate time periods.

Keeping Track Of Important Dates

With so many dates to keep in mind, it’s easy for taxpayers to get overwhelmed. To avoid missing any important deadlines, it is advisable to create a calendar schedule with detailed timeframes and also accounts for any additional extensions that may be relevant. This ensures adequate time to prepare relevant documentation and other requirements.

Several digital tools, such as Google Calendar, can be leveraged, which allow alerts to be set beforehand before the due date. There are state revenue service-affiliated software or third-party solutions like TurboTax, H&R Block, etc., available too.

Tips For Smooth State Tax Filing

Here are some tips that can help make state tax filing smoother:

  • Be organized: Keep accurate records of all your income sources.
  • Understand Your Forms: Stay informed on forms like W-2s, 1099s.
  • E-filing: If possible, try E-filing instead of traditional paper-based submissions. This is especially valuable during ongoing uncertainties related to the Covid Pandemic.
  • Look up potential deductions. Many states offer various types of incentives, including credits based on specific investments made. Therefore, it’s worth cross-checking prior to the filing deadline.

By being aware of these nuances in advance and executing properly, you should have a smooth experience overall concerning the upcoming tax season. Remember: Mark your calendars and plan well ahead!


In conclusion, filing state taxes by their respective deadlines is essential for staying compliant under tax regulations. By marking important dates early on, maintaining accurate bookkeeping records, double-checking all documents, and exploring deductions where applicable, you could save both money and time. Investing a bit extra in pre-planning will pay off in the long run while avoiding costly penalties associated with non-compliance.

Penalties range from interest accrued on outstanding balances, late fees charged as a percentage of overdue amounts owed, such as.5% per month (or fraction thereof) up to a maximum of 25 percent, and collection actions like wage garnishment, levies, liens/payment plan defaults, among others.
