A recent Wall Street Journal illustration of the upcoming tax changes used four example households.

The lowest household income used? $180,000 per year — for a retired couple! — which is more than 94% of all households.

The other examples:

• Single person, $230,000 (97th percentile)
• Single parent, $260,000 (1.5% of all US households)
• Married couple, $650,000 (top 1% of all households)

Median household income in the US, by the way, is a little over $45,000 per year.
