When do k 1s have to be mailed

In the United States, the deadline for mailing Form K-1 (Schedule K-1) to shareholders is typically March 15th of each year, unless the partnership's tax year is a calendar year, in which case the deadline is April 15th.

Form K-1 is used to report the share of income, deductions, credits, and other items from a partnership to the Internal Revenue Service (IRS) and to the individual partners. The form is typically prepared by the partnership and mailed to each partner by the deadline.

Here are some key dates to keep in mind:

It's important to note that these deadlines apply to the mailing of the Form K-1, not the filing of the partnership tax return (Form 1065). The partnership tax return is typically due on March 15th or April 15th, depending on the partnership's tax year.

If you're a partner in a partnership, it's a good idea to check with your partnership or tax professional to confirm the deadline for receiving your Form K-1 and to ensure that you receive it on time.
