Then consider the deduction for half the SE tax.  Then consider whether the retirement savings credit will be reduced.  Also, what about state income tax?

I used it once for a Civil Service retiree who had nine years of Social Security credits and needed ten to collect benefits.  It's been about a dozen years now, and she gets $3,200 a year.  Enough to pay Medicare, and to pay me, and to pay the tax on her Civil Service pension, which would not be enough to be taxed if she hadn't made the mistake of going to work for the federal government in the first place.
