Key Federal Tax Deadlines for 2023

Key Takeaways
  • Individual income tax returns are typically due by April 15, unless the date falls on a weekend or holiday. That said, the IRS is very lenient when it comes to granting a six-month extension.
  • Generally, partnerships, multi-member limited liability companies (LLCs) and S corporations (S corps) must file their income tax returns by March 15, unless they operate on a fiscal year. Similar to individual returns, a six-month extension is available.
  • In addition to the tax filing deadline, businesses must also comply with distribution deadlines for W-2s and 1099s.
  • Self-employed individuals need to comply with deadlines for making quarterly estimated tax payments to avoid underpayment penalties.

What Is the Individual Federal Income Tax Deadline for 2023?

The last day to file individual federal income tax returns is usually April 15, unless this date falls on a weekend or holiday. For 2023, April 15 falls on a Saturday, which pushes the deadline to Monday, April 17. However, Monday is Emancipation Day, which defers the deadline to Tuesday, April 18.

Did you know?
If you reside in the state of California, your filing deadline has been extended to May 15, 2023 due to the season’s extreme winter storms. The extension aims to help alleviate some of the stress many have endured during this trying time.

What Is the Deadline To File an Extension?

Typically, the Internal Revenue Service (IRS) will grant a six-month extension of the tax filing deadline to anyone who requests it. You can request an extension by filing Form 4868. If you opt for an extension this year, your filing deadline will be Oct. 16, 2023.

Note that the extension gives you more time to file your return, not more time to pay your tax obligation. If you have not withheld an adequate amount of federal taxes from your paychecks or made estimated quarterly payments for other than W-2 income, you need to estimate the amount of tax you owe and make a payment to the IRS by April 18, 2023.

For U.S. citizens and resident aliens living abroad, the tax filing deadline for 2022 returns is June 15, 2023.

What Are Other Federal Tax Deadlines for 2023?

For partnerships, multi-member limited liability companies (LLCs) and S corporations (S corps), income tax returns are typically due on or before March 15, unless they operate on a fiscal year basis.

For businesses that operate on a fiscal year basis, returns are typically due on or before the 15th day of the third month after the close of the fiscal year. In instances where the due date falls on a weekend or holiday, the due date is moved to the next business day.

In addition to the tax filing deadline, businesses also need to be aware of the deadlines for distributing W-2s and 1099s to their labor forces. For self-employed individuals, you need to be aware of the deadlines for making quarterly estimated tax payments to avoid underpayment penalties.

Other Important 2023 Tax Dates

Beyond the deadlines outlined above, there are several other important tax dates to keep on your personal-finance radar. These dates pertain to when the IRS begins accepting certain information, due dates for certain forms and actions and cut-off dates for making contributions to IRS-qualified savings plans.

  • Jan. 23, 2023
    The commencement of the 2023 tax season. This is the first day the IRS will begin accepting and processing 2022 tax returns.
  • Feb. 15, 2023
    The deadline to reclaim your exemption from W-2 withholdings. If you claimed an exemption from W-2 withholdings last year, you need to refile a Form W-4 to continue the exemption. Doing so only makes sense if you anticipate having no tax liability.
  • April 3, 2023
    The deadline for taking your first annual required minimum distribution (RMD) if you turned 72 in 2022.
  • April 18, 2023
    The deadline to make individual retirement account (IRA) and health savings account (HSA) contributions for the 2022 tax year.
  • Dec. 31, 2023
    The deadline for taking your annual RMD, assuming you’ve been responsible for taking one in previous years. If you’ve never had to take one, the Secure 2.0 Act of 2022 may have extended things for you. Unless you reach the age of 73 prior to the end of 2023, you do not need to begin taking an RMD this year. Incidentally, if you turned 72 in 2022, after taking your first RMD by April 1, 2023, you must also take your 2023 RMD by the end of the year.

All dates noted are subject to change by the IRS. As a result, it’s a good idea to periodically check the IRS website for updates throughout the year.

Other Frequently Asked Questions About Tax Deadlines

What happens if you miss a tax deadline?
If you owe taxes and miss a filing deadline, you will be subject to a failure-to-file penalty, a failure-to-pay penalty, as well as interest. If you do not owe taxes, you won’t face any monetary repercussions. However, unless you file your taxes, you won’t be able to recover any overpayments held by the IRS. Generally, after three years the overpayments become the property of the IRS.
What should you do if you owe more than you can afford to pay?
If you owe taxes and do not pay them by the deadline, you will be subject to penalties and interest. However, you can limit the penalties by paying as much as you can and establishing an installment plan with the IRS to repay the balance.
Can I refile my taxes if I made a mistake?
Generally, you have three years to file an amended return. So, if you make a mistake on your 2022 filing, you can file an amended return any time prior to April 18, 2026. That said, you cannot file an amended return until the initial return has been processed by the IRS. To file an amendment, you need Form 1040-X and any forms or schedules you’re modifying or didn’t include with your initial return.
Do tax deadlines vary by state?
Most states adopt the federal deadline for income tax returns. However, some states maintain their own deadlines. Check with your state tax authority for specifics.
