Form 7004 Due Dates for 2025 Tax Year
As an extension form, the deadline to file IRS Form 7004 and request an additional 6 months of time to file your business or estate tax return will be based on the type of form you are requesting the extension for and the end date of said business’s tax year.
Businesses owners must file Form 7004 extension for the 1120, 1120S, 1065, 1041 tax returns within the due date. Form 7004 provides businesses an additional 6 month of time to file their business tax returns. Businesses operating as a Single Member LLC or Sole Proprietorship must file Form 4868 to obtain a tax extension.
The deadline/due date for Form 7004 extension will differ based on the organization’s tax year (Calendar tax year vs Fiscal tax year and the return for which the 7004 extension is being requested).
