Thank you, I've read the link and my understanding is as per following example. I'm ignoring the 3K exemption each year. Assuming each inheritance was from a Class A Donor.
Person A received an inheritance of 332,084 in July 2011. No tax liability that year. They then received 6K in July 2012. Tax due 1,800.
Person B received an inheritance of 80K in July 2011. No tax liability that year. They then received 252,084 in July 2012. Add both sums together 332,084. This exceeds current 250K limit by 82,084. Tax due is 24,625.
If this is correct Person A has a distinct advantage. Is this correct.
