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.
When you place assets in an irrevocable trust, it's as if you transferred control of them to a separate person. The trust files its own tax return, based on whatever income the assets earn over the year. It also gets to take deductions: if your trustee donates money to charity, the trust takes the write-off. The trust can take a deduction equal to 100 percent of its income for the year, but no more than that.
