Important limits
This is a simplified screening estimate. It does not model deductions, prior taxable gifts, portability, valuation rules, credits, graduated rates, state estate or inheritance taxes, generation-skipping transfer tax, or filing requirements.
Do not use this result for estate planning or filing without qualified tax and legal review.
