Our experiences are very different. I want to address two points where our opinions diverge:
Your basis in property received as a gift is the same as the donor’s, unless you subsequently sell the property for less than the fair market value (FMV) at the time of the gift, in which case your basis is said FMV. This ’unless’ prevents people from gifting capital losses to other taxpayers who have capital gains that could otherwise be reduced.
Your basis in inherited property is the FMV at the time of death. Property doesn’t need to pass through probate to get the basis step-up (or step-down). Some examples of property specifically excluded from probate are accounts with named beneficiaries and property in living wills. I also believe that different states have different requirements for probate. And executors don’t have liability for the tax cheating of beneficiaries, and wouldn’t even know it had occurred.
These are my informed, though possibly not completely up-to-date opinion. Please consult a qualified tax professional before co, mmitting to any tax evasion strategies (tax avoidance = legal, tax evasion = illegal)
