I filed and suspended when I turned 66 (I'm 67 now). I salary increased substantially this past year so will my PIA be recalculated to reflect the higher 35 year average when I actually take benefits at age 70?

Hi,

Yes, Social Security automatically recalculates the benefit rates of beneficiaries who have earnings high enough to raise their benefit amount, even if their benefits are in suspense (https://www.ssa.gov/pubs/EN-05-10070.pdf).
