The death of a partner in a two-person partnership will terminate the partnership for federal tax purposes if it results in the partnership's immediately winding up its business (Sec. 708(b)(1)(A)). If this occurs, the partnership's tax year closes on the partner's date of death. Similarly, the death of a partner in a two-person partnership generally will cause the technical termination of the partnership under Rev. Rul. 99-6. The regulations, however, provide two exceptions that prevent an immediate termination of the partnership of a two-person partnership upon a partner's death.
