FAQ
  • Do I need to file Form 8308 for every partnership interest sale?

    Yes, you must file a separate Form 8308 for each Section 751(a) exchange of a partnership interest, unless a Form 1099‑B is required for the same transaction.

  • Can I file Form 8308 electronically?

    The IRS does not currently accept electronic submissions for Form 8308. You must print the completed PDF and mail it to the IRS address provided in the form’s instructions.

    Form 8308 must be filed by the due date (including extensions) of the partnership’s return (Form 1065) for the tax year in which the exchange occurred.

    Failing to file Form 8308 on time can result in penalties for the partnership and the partners involved. The penalty amount depends on the length of the delay.

  • Do I need a tax professional to complete Form 8308?
