Calculating efficiency over a period of time can identify opportunities to reorganize staffing, or add or remove employees based on the company's volume of business, and an individual employee's long-term productivity can factor into merit increases and bonuses.
While trusts avoid probate, they don't avoid taxes. A transfer from a revocable trust will be taxed the same way as a transfer made through a will. Someone who inherits money from a revocable trust receives it tax-free, but the estate might have to pay estate tax on everything that it contains before distributing it.
State taxes on family trusts vary, but federal laws require family trusts to pay taxes on income it keeps but not on any that is distributed. A trust that earns $50,000 and distributes it all to trust beneficiaries pays no income tax. The beneficiaries pay income taxes on funds given to them.
