In 2017 I was finishing my Spring semester in college. I had an internship from January-April, which I filed under 1 address. Then From May-August I moved to DC but subleased so didn't have an official address, however for my new internship I was filed under the address I lived at in DC. In September, I moved back to North Carolina for a full-time job, of course under address #3. So now I have 3 different W-2s under different employers with 3 different addresses. Will this be a problem when doing my taxes for 2017?
For the federal taxes, it is no problem at all.
For state taxes, just be aware that you probably had state tax withheld from multiple states. Look at your W-2’s closely to determine where all of your state taxes were sent. You may need to file a state tax return with more than one state.
