I'm not sure how to shove $500 into a Roth IRA. Vanguard mins are $1000 for their funds, but you might be able to get it into a money market account or something of the like.
No tax forms, extra paper work or the like for DIRECT Roth IRA contributions. You'll receive a 5498 in May the following year from whom ever houses your account. Keep this, as it is the best way to keep track of your basis.
