Should I claim 1 or 2 exemptions on my w-4. Im single no kids.

I am a government contractor. With the last contract, which lasted 5 years, I had 1 federal withholding on my pay stub the entire time. We just started the current one on 1 Sept 17 and I now have 2. I don't know what I did wrong on my W-4. I do not want to owe money at tax time. Should I change it?

Yes you should change it ... and to make up for the error claim zero allowances on line 5 for the rest of the year... then if you like the usual refund you used to get then change it to one allowance at the beginning of the year.

Thank you Critter#2.
