Summary

Explains how to figure a partner’s adjusted basis in a partnership interest. Start with the partner’s original basis from contributing property or from buying the interest. Increase it by the partner’s share of the partnership’s taxable income, any tax‑exempt partnership income, and depletion deductions that exceed the property’s basis. Reduce it (but not below zero) by partnership distributions and by the partner’s share of partnership losses and nondeductible expenses not charged to capital. Also reduce it by oil‑and‑gas depletion taken, only up to the partner’s share of that property’s adjusted basis. The Treasury can make rules about using a partner’s share of partnership property to figure basis when the partnership ends.
