After you file

Instead of claiming exempt, you could enter extra allowances to limit how much is withheld from your paycheck,  In your case, you are OK, since you have enough  personal exemptions,  standard deduction,  & credits, etc to keep your income from being taxable.  But if your income increases, be careful about saying you are exempt.  With the new tax laws it will be interesting.  New W-4's will be coming out soon and there will be no personal exemptions.
