2024 Important Tax Deadlines & Dates for Individuals & Businesses

The IRS will open for business on January 29. This is the day the agency will start accepting and processing tax returns for the 2023 tax year. If you file before then, your tax preparer will just hold onto your return until then. The agency issues most refunds in less than 21 days.

Its Free File program income limit has been increased to $79,000 for 2023. Eligible taxpayers can file their taxes at no cost through participating softwares.

For individuals, the last day to file your 2023 taxes without an extension is April 15, 2024. If you have a business that operates on a fiscal year basis, your return is typically due on or before the 15th day of the third or fourth month (depending on the type of business entity) after the close of your fiscal year. In instances where this due date falls on a Saturday, Sunday, or legal holiday, the due date is moved to the next business day.

The easiest way to check a refund's status is by using Where's My Refund? on IRS.gov or the IRS2Go app.

January 29

  • Tax filing season begins. The IRS begins to accept and process federal tax returns Jan. 29. Note that if you applied for certain credits, like the earned income tax credit or the additional child tax credit, the agency will not issue your refund until at least mid-February.

January 31

  • 1099 deadlines. Various 1099 forms, and forms 1099-NEC,1099-MISC, and 1099-K are used to report payments that typically don’t come from an employer, such as if you work as an independent contractor, gig worker, or self-employed person or if you receive income such as interest, dividends, prize winnings, rents, royalties, or brokerage account transactions. If January 31 falls on a weekend or holiday, these forms are due to be sent the following business day.

February 15

  • Form W-4 deadline for tax-exempt status. If you were exempt from tax withholding in 2023, this is the deadline to file a new Form W-4 with your employer if you intend to reclaim the exemption for 2024.
  • Informational returns like the 1099-Bs (for income earned from the sale of certain securities) and certain 1099-MISC forms must be sent to recipients by this date.

April 15 is the Federal tax filing deadline (unless extended due to local state holiday).

  • This is the date by which you must file your taxes with the IRS. This is also the deadline to file for a tax extension. Remember, a tax extension gives you more time to submit your return, not pay your taxes.
  • HSA and IRA contribution deadline. The last day to make contributions to your health savings account or a Roth/traditional individual retirement account for the tax year 2023.

Mid-July

  • Deadline to claim 2020 tax refund. This is typically the final month to file a tax return to claim a refund for a prior-year return going back three years.

October 15

  • Filing for an extension by April 15 gives you until Oct. 15 to finalize your returns. If you miss this deadline, your return is considered late by IRS and the penalties will begin to pile on.
  • SEP and Simple IRA, Solo 401(k) contribution deadline. Those who have established any of the self-employment retirement plans listed above and who timely filed for an extension in April have until Oct. 15 to make a final contribution to these plans for the 2023 tax year.

December 31

  • 401(k) contributions deadline. If you contribute to an employer-sponsored retirement plan like a traditional or Roth 401(k), Dec. 31 is typically the last day to make a qualified contribution.
  • If you’re required to take RMDs (Required Minimum Distribution for individuals age 73 or older), you must do so by Dec. 31.
  • If you itemize deductions and want to donate to charity to reduce your taxable income, this is the last day to do it for the 2024 tax year.

Businesses - Partnerships (including LLCs), C Corps, and S Corps

March 15, 2024

  • Taxes are due for some business types (partnerships, multi-member LLCs, and S-Corporations). Businesses organized as partnerships, including multi-member LLCs, and S-Corporations need to file Form 1065, or 1120S by March 15, 2024, if they are a calendar year business. If your business uses a fiscal year, you need to file your tax return by the 15th day of the third month following the close of your tax year. For example, if your business uses an April 1 - March 31 tax year, your business tax return would be due June 15 instead of March 15.

April 15, 2024

  • Taxes for C-Corporations are due. Businesses organized as C-Corporations need to file form 1120 by April 15, 2024, if they are a calendar year business. If your business uses a fiscal year, you need to file your tax return by the 15th day of the third month following the close of your tax year.

September 16, 2024

  • Deadline for extended partnership and S-corporation returns.

October 15, 2024

  • Deadline for extended C-corporation returns.
