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.

  • What is the filing deadline for Form 8308?

    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.

  • Is there a penalty for late filing?

    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.

  • Can I use the same PDF for multiple exchanges?

    No. Each exchange requires its own completed Form 8308. Use the fillable PDF to create a new document for every transaction.

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

    While a tax professional can help ensure accuracy, the fillable PDF and step‑by‑step instructions on Formize make it straightforward to complete the form yourself.

  • Where do I mail the completed Form 8308?
