Yes, If you had multiple jobs that combined totaled over $12,400 you will have to file a tax return. The income from any one W-2 must be combined into a total of all income to determine if you have to file.
Also, you may want to file, because any Federal or State income tax that was withheld could come back to you as a refund. You will not get a refund if you don't file.
You may be able to file for free with TurboTax.
