Do 401k and IRA Contributions Reduce My Social Security Benefits?

Mike Piper, author of The Oblivious Investor Blog, explains:
“pre-tax contributions that you make to an employer-sponsored retirement plan such as a 401(k) reduce your income tax, but they do not reduce your Social Security tax. The same goes for traditional IRA contributions, as well as contributions to a SEP or SIMPLE IRA.
And because they have no effect on the amount of your income that’s subject to Social Security taxes, pre-tax contributions to an IRA, 401(k), 403(b), etc. do not reduce the Social Security benefits that you will eventually receive.”
