WebOct 1, 2024 · PTPs are by default taxed as corporations; however, if the gross income of a PTP consists of 90% or more of certain types of passive income, it is treated as a partnership. The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems. PTP is employed to synchronize financial transactions, mobile phone tower transmissions, sub-sea acoustic arrays, and networks that require precise timing but lack access to satellite navigation signals.
