I have heard there are behind-closed-door bipartisan meetings going on in which extending or eliminating the taxable max couple with a new 'bend point' in the benefit formula which would be at a very low benefit rate such as 1 or 2%. No idea if this is getting very far behind the discussion stage. This will be another added tax on high income earners with a transfer to lower income workers (by allowing social security to keep its promises.)
Current bend points for AIME (average indexed monthly earnings from work history/taxes paid):
0-$1,286 -- 90%
$1,286-$7,749 -- 32%
$7,749 - $13,925 -- 15%
$13,925 is highest AIME based on hitting taxable max for 35 years and retiring at 67.
Benefits at these bendpoints
$1,286 -- $1,157/month, 90% of AIME
$7,749 -- $3,225/month, or 42% of AIME
$13,925 -- $4,151/month, or 30% of AIME
The rumored proposal would add a new bendpoint, say at $13,925
0-$1,286 -- 90%
$1,286-$7,749 -- 32%
$7,749 - $13,925 -- 15%
>$13,925 -- 2% (?)
A person with AIME under this proposal of, say, $30,000 per month, would get a benefit of $4,472 per month, or just under 15% of the hypothetical $30,000 of AIME. So that person would pay 12.5% of income on the additional $16,000 of monthly earnings for 35 years in order to get an additional $321 per month. Making a bad deal worse for them. But, this would be going a long way to restoring fiscal stability to social security. Another added layer of redistribution.
