The process begins before the K-1s are even received. As early as Q4 of the prior year, the accounting team should coordinate with the company's investment partners and external tax preparers. These conversations help set expectations for delivery timing, anticipated income or loss, and any known one-time events that could impact reporting. For example, if a major asset sale or reorganization is expected in a fund, that should be flagged so the accounting team is ready to record and reconcile the impact once the K-1 arrives.
