2024 Tax Filing Deadlines for Business Entities

Based on the provided documents, here are the comprehensive filing deadlines for various business entities in 2024:

C Corporations

For domestic C corporations and foreign C corporations with an office or place of business in the United States, the income tax return (Form 1120) is due on the 15th day of the fourth month following the close of the taxable year. Tresuary Reg. 1.6072-2

For calendar year C corporations, this means:

  • Due date: April 15, 2024
  • Extension: An automatic 5-month extension (until September 15, 2024) is available for C corporations with a December 31 year-end by filing Form 7004 before the original due date.

Special cases:

  • For C corporations with a fiscal year ending on June 30 (for tax years beginning before January 1, 2026), the return is due on the 15th day of the third month following the close of the taxable year. Short periods ending in June are treated the same way. Tresuary Reg. 1.6072-2
  • For C corporations with a June 30 fiscal year-end, a 7-month extension is available (instead of the standard 6-month extension). IRC § 6081(b)

S Corporations

S corporations must file their income tax returns (Form 1120-S) by the 15th day of the third month following the close of the taxable year. Tresuary Reg. 1.6072-2

For calendar year S corporations:

Partnerships

Partnership returns (Form 1065) made on the basis of the calendar year must be filed on or before the 15th day of March following the close of the calendar year. For fiscal year partnerships, returns must be filed on or before the 15th day of the third month following the close of the fiscal year. IRC § 6072(b)

For calendar year partnerships:

  • The due date is March 17, 2024 (since March 15 falls on a Saturday). Partners must be provided with a copy of their Schedule K-1 (Form 1065) and, if applicable, Schedule K-3 (Form 1065) by this date. An automatic 6-month extension can be requested by filing Form 7004.

Foreign Corporations

The due date for foreign corporations filing Form 1120-F depends on whether they have an office or place of business in the United States:

Information Returns (Forms 1099)

Returns made under section 6041 on Forms 1096 and 1099 for the 2023 calendar year must be filed on or before February 28, 2024, if filed on paper, or March 31, 2024, if filed electronically. Tresuary Reg. 1.6041-6

The required filing date for Forms 1099-B (relating to proceeds from broker and barter exchange transactions) is February 28, 2024, for paper filing. Under regulations, a person required to file at least 10 returns during calendar year 2024 must file those returns electronically. T.D. 9972

Failure to file information returns timely can result in penalties. For example, for the 2023 calendar year, if Forms 1099-MISC are filed after the deadline but within 30 days, there’s a reduced penalty of $50 per form. If filed after 30 days but on or before August 1, 2024, the penalty is $100 per form. If filed after August 1, 2024, the penalty increases to $250 per form.

Form 1042 (Withholding Tax Return)

The electronic filing requirements apply to Forms 1042 required to be filed for taxable years ending on or after December 31, 2023. These forms are due on or after March 15, 2024. Notice 2024-26

Estimated Tax Payments

For individuals (including business owners who pay estimated taxes): There are 4 required installments for each taxable year, due on:

  • 1st installment: April 15
  • 2nd installment: June 15
  • 3rd installment: September 15
  • 4th installment: January 15 of the following taxable year

For 2024, a calendar year taxpayer’s estimated tax payments are due on April 15, 2024; June 15, 2024; September 15, 2024; and January 15, 2025. IRS – Publication 559: Survivors, Executors and Administrators

Trusts and Estates (Form 1041)

An automatic 5½-month extension of time to file Form 1041 can be requested by filing Form 7004. The extension is automatic, so no signature or reason for the request is required. Form 7004 must be filed on or before the regular due date of Form 1041.

An extension of time to file a return doesn’t extend the time for payment of tax due. The total income tax estimated to be due on Form 1041 must be paid in full by the regular due date of the return.

Special Considerations

Weekend and Holiday Rules

If the due date falls on a Saturday, Sunday, or legal holiday, the corporation can file on the next day that isn’t a Saturday, Sunday, or legal holiday.

If the filing deadline falls on a Saturday, Sunday, or legal holiday, the deadline is extended to the next day that is not a Saturday, Sunday, or legal holiday, per IRC § 7503.

For example, traditionally, the filing deadline for individual tax returns is April 15. However, if this date falls on a weekend or a legal holiday in the District of Columbia, the deadline is extended until the following business day.

Disaster Relief

The IRS provides relief, including postponing various tax filing and payment deadlines, for any area designated by the Federal Emergency Management Agency (FEMA) as a disaster area. If a taxpayer’s address of record is in a disaster area locality, individual and business taxpayers automatically get the extra time without having to ask for it.

Electronic Filing Requirements

A person required to file at least 10 returns during calendar years 2024 and after must file those returns electronically. Failure to correctly file these returns electronically by August 1, 2024, can result in penalties. T.D. 9972

Important Notes

  • Whenever possible, you should take action before the listed due date. If you’re late, you may have to pay a penalty as well as interest on any overdue taxes. In addition to civil penalties, criminal penalties may be imposed for intentionally not paying taxes, for intentionally filing a false return, or for not filing a required return.
  • You can use certain private delivery services (PDSs) designated by the IRS to meet the timely mailing as timely filing/paying rule for tax returns and payments.
  • When correcting previously filed employment tax returns, the due date for filing the correction depends on the original form. For example, if on June 10, 2024, an employer discovers an error with Form 943 filed for the 202312 tax period, they must file Form 943-X by January 31, 2025, to qualify for an interest-free tax adjustment.

Remember that these deadlines are specific to the 2024 tax year, and it’s always advisable to consult with a tax professional regarding your specific situation and to verify any changes to tax deadlines that may occur after this information was provided.
