The calculation YttriumNitrate mentioned is done globally at retirement for your 35 highest earning years. So if you've already made $371,700 in wages ($885*12 months*35) that had SS taken out of them over your entire lifetime,* you've already go the highest bag for buck part of your social security check covered for life. If you make it to $2.25M ($5336*12 months * 35 years), the value of additional social security eligible wages drops again.
I could see trying to game the system if you're below $371,700 in covered wages and expect to retire before you hit that cap. At that point, each extra $100 of social security eligible income means paying $6.20 in taxes, but increases your annual social security checks by $2.57 (the equivalent of buying an annuity with 41.5% annual return). Even if you figure in the likely cuts to SS's payouts in coming years, and that fact you'd likely also end up paying some additional taxes in the process of trying to increase your social security eligible income, that remains a pretty good deal. However, if you expect to have earned more than that amount in SS covered wages by retirement, I wouldn't worry about it.
*There is even an inflation calculation that adjusts the value of wages earned in earlier years upwards, so the actual cut off is likely less than that.
**Our numbers are slightly different but it's just because these were also adjusted for inflation between 2016 and 2017.
