A county-level inheritance tax, not a state one
County Court, not District Court
Nebraska adopted the Uniform Probate Code but differs from most other UPC states by handling probate through the County Court rather than the District Court — a genuinely distinctive structural choice.
No statutory fee percentage
Personal representatives are entitled to reasonable compensation with no fixed percentage (§30-2481) — a court can review the fee if anyone with an interest in the estate objects, and the same standard applies to any attorney or professional the PR hires.
Who withholds the inheritance tax, and when
The tax is technically the beneficiary's obligation, but the personal representative typically withholds it from distributions before paying beneficiaries, and it must be paid within 12 months of death. See Capital Gains Tax on the Sale for Nebraska's separate income tax treatment of the gain itself.
