I'm starting a graduate program in 2017 where I'll get a stipend. I don't think I'll receive a W2 because I won't be working for the wages, so I don't think I can contribute to my IRAs while I'm in school. Obviously there is no 401K either, traditional or Roth.
Do I have any options for saving for retirement in a tax-advantaged way? I know I can just use a brokerage or savings account, but I'm talking about options where either the money is contributed pre-tax or the earnings aren't taxable, like a traditional or Roth IRA/401K.
Also I'm not worried about liquidity or anything like that, so the sources I find that say "don't save for retirement as a grad student because you'll need the money while you're in school" aren't relevant to my situation. I'm specifically asking about what vehicles are available to me for tax-advantaged retirement savings.
