<prompt> Human: Since Im in school, Ive been getting a few thousand back each year in my tax return. Im thinking that, instead of having my current employer withhold a portion of my paycheck, I would invest that money into something for a year and then use money from there to pay my taxes. So far Im thinking the Robinhood app would be the way to do it as long as I spread it around safely. What do you all think?  <response>: Do not invest money when you need it in less than a year.
