So I've decided to start a Roth IRA but talking to a few colleagues of mine they said that there's a few fees and stuff that comes with it such that if you don't put in quite a bit of money each year then it's not worth it. I only make about $3-5k a year in the summer and use roughly $1.8k through the school year. I also like to leave a little bit in case of emergencies so that makes it about $1k-3k a year that I can put into an IRA, is that enough?
Also, slightly unrelated question but I've read that taxable income is income after subtracting exemptions. Since I make so little such that all my income is exempt, does that mean I have no taxable income?
