However, those entities get the name “flow-through” or “pass-through” because they do not pay income tax.
As a flow-through, your business’s income and losses get passed on to the partners, owners, and shareholders. So when your flow-through entity files a Form 1065 to the IRS, you must also issue Schedule K-1s to each partner or shareholder for them to report on their individual returns. For this reason, if you plan on electing to extend your tax deadline, be sure and let all partners and shareholders know so they can do the same!
​
What Individuals and C Corps Need to Do By Their Tax Dead line As an individual (including sole proprietors) or corporation, your taxes are due on the fifteenth day of the fourth month of your fiscal year or the fifteenth day of the tenth month if you file an extension. This means you will file your taxes or an extension on April 15, 2019, and pay any tax liability you owe. If you ask for an extension, you will file taxes by October 15, 2019, but you will still need to pay taxes by April 15.

What Exempt Organizations (Nonprofits and Charities) Need to Do By Their Tax Deadline As an exempt organization, such as a nonprofit or charity, you will file taxes on the fifteenth day of the fifth month of your fiscal year or the fifteenth day of the eighth month if you file an extension. For your 2018 return, you will need to file your taxes or an extension by May 15, 2019. If you ask for an extension, you will have until August 15, 2019 to file your return.
