If you’re counting on receiving a refund that’s similar to last year’s, you may want to adjust your thinking. The IRS has cautioned some filers’ tax refunds may be less this year due to changes in the amounts for the Child Tax Credit, Earned Income Tax Credit and Child and Dependent Care Credit.

No matter whether you receive a tax refund or not, it’s important to avoid errors and meet all IRS deadlines when filing your taxes, which starts by knowing these key dates on the tax season calendar.

Important Dates and Deadlines for Tax Season 2023

The following is a schedule of the most important days and events of this year’s tax season, but you’ll want to pay special attention starting in April! You need to know about these deadlines whether you work for an employer, work for yourself, or both.

  • January 14: The IRS Free File is set to open to the public in January, when taxpayers begin filing their returns through the third-party partners of the IRS Free File program. The exact date is unknown at this point, but last year, the IRS Free File opened on Jan.14.
  • January 17: This is the deadline for estimated tax payments for the fourth quarter of 2022. If you work for an employer who withholds taxes from your paycheck, you don’t have to pay estimated quarterly taxes, but many self-employed people do.
  • January 23: This is the official start of the 2023 tax season and the date that the IRS will begin accepting and processing returns from tax year 2022.
  • January 27: This date has been designated Earned Income Tax Credit Awareness Day, which the IRS’s website says is “to raise awareness of valuable tax credits available to many people — including the option to use prior-year income to qualify.”
  • April 18: TAX DAY IS HERE — and for the fourth year straight, it will arrive after its regularly scheduled date of April 15. The delays in 2020 and 2021 were pandemic-related. However, last year, the IRS pushed back the deadline for filing 2021 tax returns and for paying taxes owed because of the Emancipation Day holiday in Washington, D.C. In 2023, the fact that April 15 falls on a Saturday and the Emancipation Day holiday on the following Monday, April 17, is also why the deadline is later. April 18 is also the last day to request an extension. You must e-file or postmark your returns, or file the Individual Tax Return Extension Form for Tax Year 2022 by midnight.
  • April 18: This date is also important because it’s the last day to make contributions to retirement accounts like traditional IRAs, both deductible and not, and Roth IRAs. This is regardless of whether or not the IRS grants you a filing extension. Additionally, April 18 is the deadline for filing estimated quarterly taxes for the first quarter of 2023.
  • April 19: If you live in Maine or Massachusetts, you must file your 2021 tax return or request an extension — and pay what you owe either way — the day after the rest of the country. Select New Englanders have Patriots’ Day to thank for the one-day reprieve.
  • June 15: Contractors, gig workers, and others whose self-employment requires them to pay estimated quarterly taxes must have their second-quarter checks in the mail by this date.
  • Sept. 15: Self-employed workers must have their third-quarter 2022 estimated tax payment postmarked by this date to avoid IRS penalties.
  • October 16: If you were granted a filing extension back on April 18, your time has run out. The due date to file your 2021 tax returns — and this time there’s no more wiggle room — is Oct. 16.
