The SSA deducts $1 for every $2 you earn over the $19,560 limit

IMO Best to retire then file SS. Then live off your assets in this order - Govt and structured annuities first, market investments last. The market tracks to inflation much better than govt plans so you assets will rise faster than your receivables.
Thanks! I was perusing that doc last night!
Not planning on SS being available in its current form anyways so invest accordingly.
