Wealth preservation plans are important. But plans are only as good as the execution of the plan.
Supportable valuation of appreciable assets should be the primary focus for those who have a need (estate tax) or desire (gift tax) to report the value of their investments in real estate, businesses, funds, securities, notes, etc. to the IRS and state taxing authorities. Reasonable, defensible valuations reduce unwanted scrutiny and may eliminate professional fees required to respond to the IRS and state tax inquiry, not to mention penalties and interest, if assessed.
