Partial Packet Functionality in K1 Aggregator
The article explains that with the new Partial Packet functionality in K1 Aggregator, users can upload federal, state, and K-3 forms immediately when received, rather than waiting for an entire packet to arrive. This streamlines workflows by eliminating manual PDF merging, enabling earlier data review and accelerating tax prep during busy periods.
Overview
K1 Aggregator's Partial Packet feature allows you to upload portions of K-1 packets as they arrive, eliminating the need to wait for complete packages before beginning your processing workflow. This functionality enables you to upload federal K-1s, state K-1s, and K-3s immediately upon receipt, significantly accelerating your tax preparation process during busy seasons.
Benefits
