Due Dates for Returns and Payments

Your filing and payment obligations and due dates will generally be based on the legal form in which you operate your business:

• sole proprietorship
• partnership or limited liability company
• C corporation
• S corporation

In addition, please note that if a due date that is set by law falls on a Saturday, Sunday, or federal legal holiday, it is delayed until the next day that isn't a Saturday, Sunday, or legal holiday. However, a statewide legal holiday delays a due date only if the IRS office where you are required to file your returns is located in that state.
