Rock And Roll Heaven by The Righteous Brothers. This talks about numerous music stars who died too young. First verse: Jimi gave us rainbows is Jimi Hendrix. Janis took a piece of our hearts is Janis Joplin. Otis took us all to the dock of the bay is Otis Redding. Remember Jim that way is Jim Morrison.
The idea is that even if you earn too much to contribute to a Roth IRA directly, you can open a Traditional nondeductible IRA and convert it to a Roth; there is no income limit on Traditional nondeductible IRAs or conversions.
(Also, at that low a tax rate, nobody would contribute to a Traditional IRA; a Roth IRA would be much better.) So the answer is, you can put $1000 into your Traditional IRA. If you somehow had it over-withheld so that you only got $900 from your paycheck, then you would get $100 from somewhere else to contribute.
